Will my Calgary home insurance cover a wood-burning fireplace without WETT inspection?

Most Calgary home insurance companies will NOT provide coverage for wood-burning fireplaces without a WETT inspection report, and some may cancel your policy entirely if they discover an uninspected wood-burning appliance during a claim.

While WETT (Wood Energy Technology Transfer) certification isn't technically mandatory under the Alberta Building Code, it has become the practical standard that Alberta insurance companies rely on to verify that wood-burning installations meet Canadian safety standards. Insurance companies view uninspected wood-burning appliances as unacceptable fire risks, especially given that wood stoves and fireplaces are involved in roughly 25% of residential structure fires in Canada.

The insurance risk is significant for Calgary homeowners. If you have an existing wood-burning fireplace or stove that's never been WETT-inspected, your insurance company may deny coverage for any fire-related claim — even if the fire wasn't caused by the fireplace. Some insurers will cancel your entire policy upon discovering an uninspected wood-burning appliance during a routine claim investigation or policy renewal inspection. This leaves you completely uninsured, which violates most mortgage agreements and creates enormous personal liability exposure.

Calgary's extreme climate makes WETT inspection even more critical. The city's long heating season means wood-burning appliances accumulate heavy use from October through April — six months of regular operation that accelerates creosote buildup and increases fire risk. Chinook wind events create unique draft challenges that can cause backdrafting and improper combustion if the installation doesn't meet proper clearance and venting standards. A WETT-certified technician understands these Calgary-specific conditions and can identify problems that a general home inspector might miss.

Getting a WETT inspection costs $250-$400 in Calgary — a small price compared to losing your entire insurance coverage. The inspection covers the appliance installation, chimney condition, clearances to combustible materials, and overall compliance with Canadian standards. If problems are found, you'll get a detailed report explaining what needs repair or modification to meet safety standards. Many insurance companies require re-inspection every few years for older installations.

For new wood-burning installations, hire a WETT-certified installer from the start. This ensures the work meets the highest Canadian standards and provides the documentation your insurance company needs. The installer will provide a WETT compliance certificate upon completion, which satisfies most insurance requirements without needing a separate inspection.

If you're buying a Calgary home with an existing wood-burning fireplace, make the sale conditional on a satisfactory WETT inspection — both for safety and insurance coverage. Don't assume that because a fireplace "looks fine" or was installed by a contractor that it meets current standards or will satisfy your insurance company.
