Do I need a WETT inspection for my Calgary wood-burning fireplace insurance?

Most Alberta home insurance companies require a WETT inspection report for homes with wood-burning fireplaces, stoves, or inserts. While not legally mandatory under the Alberta Building Code, WETT certification has become the practical standard that insurers use to verify your wood-burning appliance is safely installed and maintained.

WETT (Wood Energy Technology Transfer) is the Canadian national standard for wood-burning appliance safety. A WETT-certified technician inspects your entire wood-burning system — the appliance itself, chimney or venting system, clearances to combustible materials, and overall installation compliance with manufacturer specifications and Canadian safety codes. The inspection results in a detailed report that documents any deficiencies and confirms the system meets safety standards.

In Calgary's insurance market, most major providers including Intact, Aviva, Co-operators, and Wawanesa either require or strongly prefer WETT inspection reports for wood-burning appliances. Some insurers require the inspection before issuing a new policy, while others may request it during claims investigations or policy renewals. Without a current WETT report, you may face higher premiums, coverage exclusions for fire damage related to your fireplace, or outright policy denial. Given that wood-burning appliances are statistically higher-risk than gas or electric fireplaces, insurers use WETT certification as their primary risk assessment tool.

Calgary's extreme climate makes WETT inspections particularly important because wood-burning systems accumulate heavy use during our six-month heating season. Creosote buildup happens faster when fireplaces run regularly from October through April, and chinook temperature swings create additional thermal stress on chimney systems. A WETT inspection identifies problems like cracked chimney liners, inadequate clearances, damaged chimney crowns, or blocked flues before they become fire hazards.

WETT inspections in Calgary cost $250-$400 and should be done annually for insurance compliance and safety. The inspection covers the appliance condition, chimney interior and exterior, venting system integrity, clearances to combustibles, and proper installation of components like chimney caps and spark arrestors. If deficiencies are found, you'll receive a detailed report outlining required repairs. Once repairs are completed, a follow-up inspection confirms compliance.

Contact your insurance provider to confirm their specific WETT requirements — some want inspections within the past 12 months, others accept reports up to 2-3 years old for existing policies. For new wood stove or fireplace installations, ensure your contractor is WETT-certified and provides the inspection report as part of the installation process.
