Should you test for radon before buying or selling a home in Halifax? Yes. Roughly 36.8% of Nova Scotia homes are expected to exceed Health Canada’s radon guideline, more than double the 17.8% national average.

I’m Johnny Dulong, Family Real Estate Advisor with EXIT Realty Metro in Halifax, Nova Scotia, licensed REALTOR® (NS #NA5059). I’ve been helping buyers and sellers across Halifax Regional Municipality for 24 years, and radon is one of the inspection items I see skipped most often simply because people don’t know how common it is here. Find me at SellHalifaxRealEstate.com or call 902-209-4761.

Radon doesn’t come up in every home inspection conversation, but it probably should in Nova Scotia more than almost anywhere else in the country.

Key Takeaway

A DIY test kit costs about $50, and if mitigation is needed, a standard sub-slab depressurization system in HRM typically runs $1,500 to $3,200.

Why Radon Is a Bigger Deal in Nova Scotia Than Most Buyers Realize

Radon is a naturally occurring radioactive gas that comes up from the ground through cracks and gaps in a home’s foundation. You can’t see it, smell it, or taste it, and it’s the second leading cause of lung cancer in Canada after smoking.

Nova Scotia’s geology puts it well above the national average for radon risk. Health Canada’s guideline for acceptable indoor radon levels is 200 becquerels per cubic metre (200 Bq/m³), and close to 37% of Nova Scotia homes are expected to exceed that guideline, compared to roughly 18% nationally.

Make Sense of Radon, Government of Nova Scotia

In a 2019 Health Canada-affiliated testing initiative, more than half of the Halifax-area homes tested came in at or near that threshold, and provincial survey data has recorded readings as high as 5,012 Bq/m³ in Nova Scotia, more than 25 times the guideline, with HRM-area maximums topping out around 1,350–1,787 Bq/m³ (Spryfield East, Beechville/Regency Park).

“This isn’t a reason to panic about any specific home. It’s a reason to test, because there’s no way to know a given property’s radon level without doing it.”
Johnny Dulong, Family Real Estate Advisor

What Testing Actually Involves

Health Canada recommends a long-term test, run for a minimum of three months, since radon levels fluctuate with the seasons and a short-term test can miss the real picture.

For a real estate transaction on a tighter timeline, a short-term test, commonly 48 to 96 hours, is the more practical option and is what most home inspectors offer as an add-on to a standard inspection.

Testing Option	Typical Cost	Best For
DIY test kit	About $50	Long-term testing outside a transaction timeline
Professional short-term test	Add-on fee through your inspector	Real estate transactions on a condition-period timeline

Should You Skip the Home Inspection in Halifax? What Buyers and Sellers Need to Know in 2026

What This Means for Halifax Buyers

If you’re buying, ask your home inspector whether radon testing is included or available as an add-on before your inspection day. Given how common elevated levels are across HRM, it’s worth building into your condition period rather than treating it as optional.

If a test comes back above the 200 Bq/m³ guideline, that’s not necessarily a reason to walk away. Mitigation is a well-understood, fixable problem in most homes:

Most Halifax-area homes use a sub-slab depressurization system, which draws radon from beneath the foundation and vents it safely outside.
Professional mitigation in HRM typically runs $1,500 to $3,200 for most standard installations, with crawlspace homes sometimes landing at the higher end.
Active mitigation systems commonly reduce radon levels by 80% or more, with well-installed systems reaching up to 99%.

An elevated radon reading during your condition period gives you a concrete, priced item to negotiate, either a price adjustment, a seller-funded mitigation system before closing, or simply going in with clear eyes about a cost you’ll need to budget for afterward.

What This Means for Halifax Sellers

If your home hasn’t been tested for radon, or it’s been several years since it was, consider getting ahead of it before you list.

A few reasons this is worth doing proactively:

A recent clean test result is a concrete, positive detail you can disclose and point to, in a market where buyers are asking more questions during longer condition periods.
If your home does test high, addressing it before listing avoids a mid-transaction surprise that can stall or derail a deal during the buyer’s condition period.
It’s a reasonable, low-cost item to note on your Property Disclosure Statement alongside anything else you know about the home’s mechanical and environmental history.

This is the same logic that applies to other inspection items that surface constantly in HRM’s older housing stock: known issues addressed before listing rarely cost a sale, but issues discovered mid-transaction usually cost time, leverage, or both.

What to Do, Whether You’re Buying or Selling

If you’re buying:

Ask your home inspector whether radon testing is available as part of your inspection, and add it if it isn’t automatically included.
Budget for a short-term test during your condition period rather than assuming it isn’t necessary.
If levels come back elevated, get a mitigation quote before you finalize your decision. Most systems cost less than buyers initially expect.

If you’re selling:

Consider testing before you list, especially if your home has never been tested or it’s been more than a few years.
If you test high, get a mitigation quote and consider having the work done before listing, or disclose it clearly and price accordingly.
Keep any test results and mitigation documentation on hand to share with buyers.

Every home and every foundation is a little different, and the right approach depends on your specific property and timeline. This is exactly the kind of detail I walk buyers and sellers through as part of a complete plan, not an afterthought.

If you’re working through this for your own situation in Halifax Regional Municipality, I’m happy to walk you through the numbers and help you make a confident, well-informed decision. Book a no-pressure consultation with Johnny at SellHalifaxRealEstate.com or call 902-209-4761.

Frequently Asked Questions

How common is elevated radon in Halifax homes?

Nova Scotia has one of the highest expected rates of elevated radon in the country, with roughly 36.8% of homes projected to exceed Health Canada’s 200 Bq/m³ guideline, compared to about 17.8% nationally. A 2019 Health Canada-affiliated testing initiative found more than half of tested Halifax-area homes at or near that threshold.

How much does a radon test cost in Halifax?

A DIY test kit costs about $50 through the Lung Association of Nova Scotia and Prince Edward Island. Professional short-term testing is often available as an add-on through your home inspector for an additional fee on top of the standard inspection cost.

How long does a radon test take?

Health Canada recommends a long-term test of at least three months for the most accurate picture, since radon levels shift with the seasons. For real estate transactions on a tighter timeline, a short-term test of 48 to 96 hours is the more practical and commonly used option.

How much does radon mitigation cost in HRM?

A standard sub-slab depressurization system in the Halifax area typically costs $1,500 to $3,200, with crawlspace homes sometimes landing at the higher end. These systems commonly reduce radon levels by 80% or more, with well-installed systems reaching up to 99%.

Should I walk away from a home purchase in Halifax if the radon test comes back high?

Not necessarily. Elevated radon is a fixable, well-understood problem in most homes. An above-guideline result gives you a concrete item to negotiate during your condition period, whether that means a price adjustment, a seller-funded mitigation system, or simply budgeting for the fix yourself.

Can You Get Home Insurance for an Older Home in Halifax?

Posted on July 23, 2026 by Johnny Dulong

Can you get home insurance for an older home in Halifax? Usually yes, but insurers routinely decline or restrict coverage for knob-and-tube wiring, FPE or Zinsco panels, and aging oil tanks.

By Johnny Dulong | Family Real Estate Advisor | July 2026

I'm Johnny Dulong, Family Real Estate Advisor with EXIT Realty Metro in Halifax, Nova Scotia, licensed REALTOR® (NS #NA5059). I've been helping buyers and sellers of older Halifax homes across Halifax Regional Municipality for 24 years, and insurability is one of the quietest deal-killers I see in this market. It rarely shows up until a buyer is a week from their financing condition deadline and their broker suddenly can't bind a policy. Find me at SellHalifaxRealEstate.com or call 902-209-4761.

All of these issues, aluminum wiring, and aging roofs are common in pre-1970s HRM housing stock. Confirm insurability before you waive your financing condition, not after.

A house can sail through inspection and still fail to get insured. That's the trap. Home inspectors flag what they see; insurers decide what they'll cover. Those are two different filters, and a lot of HRM's older character stock, peninsula Halifax, Hydrostone, the older pockets of Dartmouth, Bedford, and Sackville, gets caught by the second one even when it passes the first cleanly.

No lender will fund a mortgage without proof of insurance in hand at closing. So if a property turns out to be uninsurable, or insurable only at a steep non-standard premium, that's not a cosmetic problem. It can stall or kill the deal days before closing if nobody checked earlier.

WHAT MAKES AN OLDER HRM HOME HARD TO INSURE

Four systems account for most of the insurability trouble I see in older Halifax-area homes:

Knob-and-tube wiring. This early-1900s wiring system shows up throughout Halifax's older peninsula and Hydrostone housing. Many major Canadian insurers won't write a new policy on a home with active knob-and-tube wiring at all. Others will, but only if it's confined to a small percentage of the home and kept out of high-load areas like kitchens and laundry rooms.
Aluminum wiring. Common in homes built or rewired through the late 1960s and 1970s, aluminum wiring is a known fire risk when it isn't properly terminated. Several major insurers have tightened their underwriting on it further through 2026, and coverage increasingly depends on documented repairs using approved connectors (commonly called pigtailing) by a licensed electrician.
Federal Pacific Electric (FPE) and Zinsco panels. These recalled panel brands have breakers that can fail to trip when they should, which is a recognized fire hazard. Most insurers simply won't write a new homeowner policy on a home with one of these panels still in service, full stop.
Aging oil tanks and older roofs. Insurers typically want oil tanks under roughly 10 to 25 years old depending on above-ground versus underground installation, and a roof with clear remaining service life. Both are common findings in HRM's older inventory and can trigger a decline or a requirement to replace before binding coverage.

I've written a full breakdown of the oil tank side of this on its own, and the wood stove and WETT certification angle separately. Both are pieces of the same puzzle: an insurer looking at an older home isn't just pricing the building, they're pricing every system inside it.

HOW TO CONFIRM INSURABILITY BEFORE YOU WAIVE CONDITIONS

This is the part buyers skip, and it's the part that matters most in a market where conditions are back in play. Here's what I walk every buyer through on an older HRM property:

Call an insurance broker the same week you go conditional, not after your inspection, and definitely not after you've waived financing. A broker who works with multiple carriers can tell you within a day or two whether a home is a standard risk, a non-standard risk, or effectively uninsurable as-is.
Ask the listing agent or seller for documentation on panel type, wiring type, and oil tank age. Sellers who've already had an electrical assessment or tank inspection done can move this along fast. [LINK: Nova Scotia Property Disclosure Statement | Halifax Guide → https://sellhalifaxrealestate.com/blog.html/nova-scotia-property-disclosure-statement-halifax-guide-9011401 | opens in new tab]
Get your inspector to specifically call out panel brand and wiring type in their report. A general inspection report sometimes buries this detail; ask for it explicitly. [LINK: Should You Skip the Home Inspection in Halifax?

Structure your offer with both inspection and financing conditions until insurability is confirmed, since an insurance decline can sink your financing even if the home itself passes inspection. [LINK: Johnny Dulong: Nova Scotia Offer Conditions Explained 2026 → https://sellhalifaxrealestate.com/blog.html/johnny-dulong-nova-scotia-offer-conditions-explained-2026-9030271 | opens in new tab]
If a standard insurer declines, ask your broker about non-standard or specialty markets before assuming the deal is dead. Coverage on older-systems homes is often available. It's just not a guarantee at standard rates, and premiums can run meaningfully higher.

Your specific situation, panel brand, wiring extent, tank age, roof condition, determines whether you're looking at a quick yes, a conditional yes with upgrade requirements, or a real problem. That's exactly the kind of thing worth walking through with someone who's seen this play out across hundreds of HRM closings before you're locked into a firm offer.

WHAT SELLERS OF OLDER HALIFAX HOMES CAN DO

If you're selling a pre-1970s home anywhere from the South End to Hydrostone to older Sackville or Fall River, insurability is worth getting ahead of before you list, not after an accepted offer falls apart.

Get an electrical assessment done pre-listing if you're not certain what's in your panel or walls. A clean report is a selling point you can put in front of buyers directly.
Disclose known wiring type, panel brand, and oil tank age accurately on your PDS. Buyers and their insurers will find out either way. Disclosing early builds trust and avoids a late-stage collapse.
Consider a pre-listing panel upgrade if you have an FPE or Zinsco panel. It typically costs a few thousand dollars and can be the difference between a full buyer pool and a shrinking one as more insurers tighten standards.

If you're working through an insurability question on a specific Halifax-area property, whether you're buying an older character home or trying to figure out what to disclose before you list one, I'm happy to walk you through the numbers and help you make a confident, well-informed decision.

FREQUENTLY ASKED QUESTIONS

What electrical systems make a Halifax home hard to insure?

Knob-and-tube wiring, aluminum wiring without approved repairs, and Federal Pacific Electric (FPE) or Zinsco electrical panels are the three most common insurability red flags in HRM's older housing stock. Many insurers decline new policies outright on homes with an active FPE or Zinsco panel.

Can I still buy a home with knob-and-tube wiring in Nova Scotia?

Often yes, but it depends on the insurer and how much of the home still has it. Some carriers decline entirely, while others will insure a home where knob-and-tube is limited and kept out of kitchens and laundry areas. Confirm this with a broker before you remove your financing condition.

How do I find out if a home is insurable before I remove my financing condition?

Call an insurance broker as soon as your offer is accepted, give them the panel type, wiring type, and oil tank age if known, and ask for a written indication before your condition deadline. This takes most brokers a day or two and can save you from a last-minute financing collapse.

Does an old oil tank affect my home insurance in HRM?

Yes. Most insurers set age limits on oil tanks, commonly around 10 years for above-ground tanks and stricter limits or outright decline for older underground tanks, because of leak and contamination risk.

What should Halifax sellers do if their home has outdated wiring or an old panel?

Get a professional electrical assessment before listing, disclose what you know accurately on your Property Disclosure Statement, and consider a panel upgrade if you have an FPE or Zinsco panel. It widens your buyer pool as more insurers tighten their standards.

Does your older Halifax home have vermiculite insulation?

Posted on July 21, 2026 by Johnny Dulong

Posted in Asbestos, Buying Strategy, Halifax Real Estate Blog, Health & Safety, Heritage Homes, Home Inspection, Home Insurance, New to Canada, Vermiculite

Does your older Halifax home have vermiculite insulation? Possibly. Most pre-1990 vermiculite attic insulation in Canada may contain asbestos, and only lab testing confirms it, since you can't tell by looking.

By Johnny Dulong | Family Real Estate Advisor | July 2026

I'm Johnny Dulong, Family Real Estate Advisor with EXIT Realty Metro in Halifax, Nova Scotia, licensed REALTOR® (NS #NA5059). I've been helping buyers and sellers across Halifax Regional Municipality for 24 years, and vermiculite is one of those attic materials that quietly shows up on inspection reports for older character homes far more often than people expect. Find me at SellHalifaxRealEstate.com or call 902-209-4761.

If you're buying or selling a home built or renovated before the 1990s in the Halifax peninsula, the Hydrostone, North End or South End Halifax, or an older pocket of Dartmouth, Bedford, or Sackville, this is worth understanding before an inspector pulls back the attic hatch and finds it.

WHAT VERMICULITE INSULATION ACTUALLY IS

Vermiculite is a naturally occurring mineral that expands when heated, and it was a popular loose-fill attic insulation across Canada from the 1940s through the mid-1980s, including under the federal Canadian Home Insulation Program. The most common brand sold here was Zonolite.

The problem: the largest source mine supplying vermiculite to North America, in Libby, Montana, had a natural deposit of tremolite asbestos mixed in with the ore. Vermiculite insulation from that source, which made up a significant share of what was installed in Canadian homes, can be contaminated with asbestos fibres. Not all vermiculite insulation is contaminated, but there's no way to tell just by looking at it. [LINK: Vermiculite Insulation Containing Asbestos, Canadian Centre for Occupational Health and Safety → https://www.ccohs.ca/oshanswers/diseases/vermiculite.html | opens in new tab]

Homes built or last renovated before the early 1990s are the ones most likely to have it, which puts a meaningful share of Halifax's older housing stock, character homes on the peninsula, older bungalows in Dartmouth and Sackville, in the range where this is worth checking.

WHY THIS MATTERS MORE THAN IT LOOKS LIKE IT SHOULD

Asbestos fibres in vermiculite are friable, meaning they break apart and become airborne easily whenever the insulation is disturbed. Health Canada's guidance is direct: if you know or suspect you have vermiculite insulation, avoid disturbing it. Don't rake it around, don't let anyone dig through it for storage, and keep attic access restricted, especially from kids.

There's an important nuance here that gets lost in a lot of online panic about this material: Health Canada notes there's no evidence of health risk if the insulation stays sealed behind wallboards, floorboards, or otherwise undisturbed in an attic. This isn't necessarily a demolition-level emergency. It's a material that needs to be identified, handled correctly, and factored into your decision, not something to panic over the moment it's spotted. [LINK: Health Canada Advising Canadians About Potential Risks Posed by Vermiculite Insulation, Government of Canada → https://www.canada.ca/en/news/archive/2004/04/health-canada-advising-canadians-about-potential-risks-health-posed-vermiculite-insulation-may-contain-asbestos.html | opens in new tab]

WHAT THIS MEANS IF YOU'RE BUYING

A standard home inspection in HRM is a visual, non-invasive assessment. A good inspector will recognize what vermiculite looks like, flag it in the report, and recommend testing, but a standard inspection does not include lab sampling or air quality testing on its own. [LINK: Should You Skip the Home Inspection in Halifax? What Buyers and Sellers Need to Know in 2026 → https://sellhalifaxrealestate.com/blog.html/should-you-skip-the-home-inspection-in-halifax-what-buyers-and-sellers-9011016 | opens in new tab]

If vermiculite is flagged during your condition period, here's the practical path:

Don't disturb it. Don't ask to go up and look around, don't let anyone move it, and keep the attic hatch closed until you know what you're dealing with.
Get it tested. A certified environmental testing company can take a sample and confirm whether asbestos is present, typically for a modest lab fee separate from your home inspection cost.
Build the timeline into your financing and inspection conditions. Testing and getting a remediation quote both take time, so this is exactly the kind of item worth structuring into your offer conditions rather than trying to resolve in the final days before your condition deadline. [LINK: Johnny Dulong: Nova Scotia Offer Conditions Explained 2026 → https://sellhalifaxrealestate.com/blog.html/johnny-dulong-nova-scotia-offer-conditions-explained-2026-9030271 | opens in new tab]
Decide what you're negotiating for. Depending on the result, that could mean a price adjustment, a seller-funded removal before closing, or simply proceeding with clear eyes about a future cost.

A confirmed asbestos-contaminated attic isn't automatically a walk-away. It's a known, priced, fixable problem, similar in principle to how buyers handle an aging oil tank or knob-and-tube wiring, another common finding in Halifax's older housing stock.

WHAT THIS MEANS IF YOU'RE SELLING

If your home was built or last had attic work done before the 1990s, it's worth finding out what's up there before a buyer's inspector does.

Nova Scotia's Property Disclosure Statement includes an environmental section asking about known hazardous materials, including asbestos. If you know or suspect vermiculite insulation is present, disclose it. An honest disclosure, especially paired with a recent test result if you have one, is a far stronger position than a buyer's inspector discovering it mid-transaction and wondering what else wasn't mentioned. [LINK: Nova Scotia Property Disclosure Statement | Halifax Guide → https://sellhalifaxrealestate.com/blog.html/nova-scotia-property-disclosure-statement-halifax-guide-9011401 | opens in new tab]

A few pre-listing options worth weighing with your REALTOR®:

Get it tested before you list, so you're working with facts instead of buyer assumptions.
If it tests positive, get a written remediation quote so you can decide whether to remove it before listing, offer a price adjustment, or disclose it and let the buyer factor it into their offer.
If it tests negative or the material isn't vermiculite at all, that clean result becomes a concrete, positive detail you can point to.

WHAT REMEDIATION ACTUALLY COSTS

Costs vary significantly across Canada depending on attic size, accessibility, and whether asbestos is confirmed present. As a general range, vermiculite-specific abatement (removal, disposal, and re-insulation together) commonly runs $10 to $25 per square foot depending on the province and contractor, with full attic abatement projects for a typical home landing between roughly $7,500 and $15,000. A standalone lab test or Designated Substance Survey typically runs $250 to $800, and post-removal air clearance testing often runs another $400 to $700.

No confirmed Halifax-specific pricing was available for this post, and costs quoted in other provinces don't necessarily translate directly to HRM. Treat these as general Canadian ranges, not a Halifax quote, and get written estimates from a certified local abatement contractor before you budget a fixed number.

This is exactly the kind of finding worth talking through with your REALTOR® before it becomes a surprise, whether you're structuring a buyer's offer conditions or deciding how to handle a pre-listing disclosure.

FREQUENTLY ASKED QUESTIONS

How do I know if my Halifax home has vermiculite insulation?

Look for loose, pebble-like, accordion-shaped granules in the attic, usually greyish-brown or gold in colour. Visual identification alone isn't reliable proof of asbestos content, though, only a lab test on a sample can confirm whether asbestos is present, so don't rely on appearance alone to decide it's safe or unsafe.

Is it dangerous to live in a house with vermiculite insulation?

Health Canada notes there's no evidence of health risk if the insulation stays sealed and undisturbed behind wallboards, floorboards, or in an isolated attic space. The risk comes from disturbing it, since the asbestos fibres it can contain are friable and become airborne easily when moved or agitated.

Do I have to disclose vermiculite insulation when selling my Halifax home?

If you know or reasonably suspect vermiculite insulation is present, it should be disclosed on Nova Scotia's Property Disclosure Statement under the environmental hazards section. An accurate disclosure, ideally backed by a test result, protects a seller from a dispute later far more than an incomplete or silent PDS does.

Will a standard home inspection in Halifax test for asbestos in vermiculite?

No. A standard visual home inspection can identify material that looks like vermiculite and recommend testing, but it does not include lab sampling or air quality testing. That has to be arranged separately with a certified environmental testing company if the inspector flags it.

Can I still get a mortgage or insurance on a Halifax home with vermiculite insulation?

It depends on the lender and insurer, and on whether the material has been tested and, if needed, addressed. Buyers should raise it with their mortgage broker and insurance provider as soon as it's flagged during their condition period, rather than assuming it will be a non-issue or an automatic dealbreaker.

Should you test for radon before buying or selling a home in Halifax?

Posted on July 18, 2026 by Johnny Dulong

Posted in Buying Strategy, Halifax Real Estate Blog, Health & Safety, Home Inspection, Radon Testing, Real Estate Conditions, Selling Strategy

Should you test for radon before buying or selling a home in Halifax? Yes. Roughly 36.8% of Nova Scotia homes are expected to exceed Health Canada's radon guideline, more than double the 17.8% national average.

By Johnny Dulong | Family Real Estate Advisor | July 2026

I'm Johnny Dulong, Family Real Estate Advisor with EXIT Realty Metro in Halifax, Nova Scotia, licensed REALTOR® (NS #NA5059). I've been helping buyers and sellers across Halifax Regional Municipality for 24 years, and radon is one of the inspection items I see skipped most often simply because people don't know how common it is here. Find me at SellHalifaxRealEstate.com or call 902-209-4761.

Radon doesn't come up in every home inspection conversation, but it probably should in Nova Scotia more than almost anywhere else in the country. A DIY test kit costs about $50, and if mitigation is needed, a standard sub-slab depressurization system in HRM typically runs $1,500 to $3,200. Here's what the numbers actually say, and what to do about it whether you're buying or selling.

WHY RADON IS A BIGGER DEAL IN NOVA SCOTIA THAN MOST BUYERS REALIZE

Radon is a naturally occurring radioactive gas that comes up from the ground through cracks and gaps in a home's foundation. You can't see it, smell it, or taste it, and it's the second leading cause of lung cancer in Canada after smoking.

Nova Scotia's geology puts it well above the national average for radon risk. Health Canada's guideline for acceptable indoor radon levels is 200 becquerels per cubic metre (200 Bq/m³), and close to 37% of Nova Scotia homes are expected to exceed that guideline, compared to roughly 18% nationally. [LINK: Make Sense of Radon, Government of Nova Scotia → https://novascotia.ca/make-sense-of-radon/ | opens in new tab]

In a 2019 Health Canada-affiliated testing initiative, more than half of the Halifax-area homes tested came in at or near that threshold, and provincial survey data has recorded readings as high as 5,012 Bq/m³ in Nova Scotia, more than 25 times the guideline, with some HRM homes coming in near 2,000 Bq/m³. [LINK: Geoscience and Mines Branch Open File Report, Nova Scotia Department of Natural Resources → https://novascotia.ca/natr/meb/data/ofr/ofr_me_2022-49.pdf | opens in new tab]

This isn't a reason to panic about any specific home. It's a reason to test, because there's no way to know a given property's radon level without doing it.

WHAT TESTING ACTUALLY INVOLVES

Health Canada recommends a long-term test, run for a minimum of three months, since radon levels fluctuate with the seasons and a short-term test can miss the real picture.

You have two main options:

A DIY test kit, available for about $50 through the Lung Association of Nova Scotia and Prince Edward Island, some HRM libraries, and participating MLA offices.
A professional test through your home inspector, often bundled as an add-on rather than included in the base inspection fee. [LINK: Should You Skip the Home Inspection in Halifax?

WHAT THIS MEANS FOR HALIFAX BUYERS

If you're buying, ask your home inspector whether radon testing is included or available as an add-on before your inspection day. Given how common elevated levels are across HRM, it's worth building into your condition period rather than treating it as optional.

If a test comes back above the 200 Bq/m³ guideline, that's not necessarily a reason to walk away. Mitigation is a well-understood, fixable problem in most homes:

Most Halifax-area homes use a sub-slab depressurization system, which draws radon from beneath the foundation and vents it safely outside.
Professional mitigation in HRM typically runs $1,500 to $3,200 for most standard installations, with crawlspace homes sometimes landing at the higher end.
Active mitigation systems commonly reduce radon levels by 80% or more, with well-installed systems reaching up to 99%.

WHAT THIS MEANS FOR HALIFAX SELLERS

If your home hasn't been tested for radon, or it's been several years since it was, consider getting ahead of it before you list.

A few reasons this is worth doing proactively:

A recent clean test result is a concrete, positive detail you can disclose and point to, in a market where buyers are asking more questions during longer condition periods.
If your home does test high, addressing it before listing avoids a mid-transaction surprise that can stall or derail a deal during the buyer's condition period.
It's a reasonable, low-cost item to note on your Property Disclosure Statement alongside anything else you know about the home's mechanical and environmental history.

This is the same logic that applies to other inspection items that surface constantly in HRM's older housing stock: known issues addressed before listing rarely cost a sale, but issues discovered mid-transaction usually cost time, leverage, or both.

WHAT TO DO, WHETHER YOU'RE BUYING OR SELLING

If you're buying:

Ask your home inspector whether radon testing is available as part of your inspection, and add it if it isn't automatically included.
Budget for a short-term test during your condition period rather than assuming it isn't necessary.
If levels come back elevated, get a mitigation quote before you finalize your decision. Most systems cost less than buyers initially expect.

If you're selling:

Consider testing before you list, especially if your home has never been tested or it's been more than a few years.
If you test high, get a mitigation quote and consider having the work done before listing, or disclose it clearly and price accordingly.
Keep any test results and mitigation documentation on hand to share with buyers.
