WETT Inspections In Ontario: Why Every Fireplace And Wood Stove Needs Annual Certification
Fireplaces and wood stoves are common features in many Ontario homes, providing warmth, comfort, and backup heat during the winter months. However, these systems also come with risks if they are not properly installed, maintained, and inspected.
That’s where WETT inspections come in. An annual WETT inspection helps ensure your fireplace or wood-burning appliance is operating safely and meets current standards—protecting both your household and your insurance coverage.
What Is A WETT Inspection?
WETT stands for Wood Energy Technology Transfer. A WETT inspection is performed by a trained professional who evaluates wood-burning appliances, venting systems, and clearances to combustible materials.
In Ontario, WETT inspections are commonly requested by insurance companies, lenders, and homebuyers. While not a government-issued certification, WETT inspections follow nationally recognized safety standards and best practices.
Why Annual WETT Certification
Fire Safety And Carbon Monoxide Risks
Wood stoves and fireplaces operate at high temperatures and involve combustion. Over time, creosote buildup, damaged venting, or improper clearances can increase the risk of chimney fires or carbon monoxide exposure.
Annual inspections help catch small issues before they become serious safety hazards.
Changes From Wear, Usage, And Renovations
Even if a system was previously approved, conditions can change. Settling, renovations, appliance upgrades, or changes to nearby materials can all affect safety compliance.
Regular inspections ensure your system continues to meet current standards—not just the standards at the time of installation.
WETT Inspections And Home Insurance In Ontario
Many Ontario insurance providers require proof of a WETT inspection for homes with wood-burning appliances. This is especially common when starting a new policy, renewing coverage, or after a claim involving fire or smoke damage.
Without a valid inspection, homeowners may face coverage limitations, higher premiums, or even policy denial. In the event of a fire, a lack of proper documentation could complicate or delay a claim.
Having an up-to-date WETT inspection provides peace of mind and clear documentation for your insurer.
When Ontario Homeowners Need A WETT Inspection
Buying Or Selling A Home
Buyers often request a WETT inspection as part of the due diligence process. Sellers may choose to complete one in advance to avoid delays during negotiations.
Installing Or Modifying A Wood-Burning Appliance
Any new installation, replacement, or modification to a fireplace, stove, or venting system should be inspected to confirm proper setup and clearances.
Insurance Renewals And Claims
Insurers may request updated WETT documentation at renewal or following a claim, particularly if the system has been modified.
What A WETT Inspection Includes
A WETT inspection typically evaluates the condition of the appliance, the venting system, the chimney, the hearth, and the required clearances from combustible materials. Inspectors also review installation details and look for signs of damage or non-compliance.
After the inspection, homeowners receive a written report outlining findings and any recommended corrections. If issues are identified, repairs may be required before certification can be issued.
Protecting Your Home And Family
Fireplaces and wood stoves can be a valuable feature in Ontario homes, but only when they are safe and properly maintained. Annual WETT inspections help reduce fire risk, support insurance compliance, and protect your home and family year-round.
If you’re buying a home, installing or upgrading a wood-burning appliance, or preparing for winter, a WETT-certified inspection is essential for safety, insurance compliance, and peace of mind.
