How much does professional chimney sweeping cost in Ottawa for a two-storey home with a wood fireplace?

Professional chimney sweeping in Ottawa for a two-storey home with a wood fireplace typically costs $175 to $350, with most jobs landing in the $225 to $300 range for a standard Level 1 inspection and cleaning.

The final price depends on a few Ottawa-specific factors. A WETT-certified chimney sweep will assess creosote buildup, chimney height, and accessibility — a taller chimney or one requiring scaffolding costs more. If your chimney has heavy Stage 2 or Stage 3 glazed creosote (the hard, shiny black coating that forms during Ottawa's long heating season), you may need additional treatment or even a second sweep, which adds $100 to $150. Some sweeps include a basic visual inspection in the quoted price, while others charge separately for a Level 1 WETT inspection ($250 to $450). Always clarify what is included when you call for a quote.

Ottawa's extended heating season and cold winters mean your wood fireplace likely accumulates more creosote than fireplaces in milder climates. If you burn 4 to 8 cords of wood per season — typical for Ottawa homeowners using a fireplace as supplemental heat — a single annual cleaning is the minimum. Heavy users or those burning in cooler shoulder months should consider twice-yearly sweeps (fall and late winter) to keep creosote buildup manageable and reduce the risk of a dangerous chimney fire. Wood that is not properly seasoned (12 to 18 months of drying to reach 15 to 20 percent moisture content) produces dramatically more creosote, so burning wet or green wood will necessitate more frequent cleaning.

While chimney sweeping is not legally mandated in Ontario, virtually all home insurance companies now require proof of regular professional chimney cleaning as a condition of coverage for homes with wood-burning fireplaces, inserts, or stoves. If you have a claim related to a chimney fire and cannot produce documentation of recent professional cleaning, your insurer may deny coverage. This makes professional sweeping not just a safety best practice but an insurance requirement. Additionally, a WETT-certified sweep can identify developing problems — cracks in the flue liner, deteriorating mortar joints, water damage, or the chimney crown damage that is so common in Ottawa's freeze-thaw climate — before they become expensive repairs.

Schedule your chimney cleaning in spring (April to May) or early fall (August to September), well before the heavy heating season. Many Ottawa sweeps are booked solid by October as homeowners scramble to prepare for winter, and you may face delays or higher pricing. An early sweep also gives you time to address any repairs the sweep identifies before cold weather arrives.

When you are ready to book, you can browse WETT-certified chimney sweeps through the Ottawa Construction Network directory, or call three local sweeps to compare pricing, services included, and availability. Ask each one whether they are WETT-certified, whether a Level 1 inspection is included, and whether they can identify and document any repair needs during the cleaning.
