Ottawa's extreme climate is especially hard on chimneys. Exposed to wind, rain, snow, and temperature swings from -35°C to +35°C, chimneys deteriorate faster than most exterior components. The freeze-thaw cycle is the primary enemy — water penetrates mortar and brick, freezes and expands, then thaws, slowly destroying the masonry from the inside out. Chimney problems range from minor maintenance (cleaning, minor tuckpointing) to major structural issues (full rebuild above the roofline). Catchin...
Chimney inspection (Level 1): $150–$300. Visual inspection of the chimney exterior and accessible interior using the WETT standard. Recommended annually for all chimneys in use. Level 2 inspections ($300–$600) use camera equipment to inspect the flue interior and are required when selling a home or after a chimney fire. Chimney cleaning/sweeping: $150–$300 per cleaning. Removes creosote buildup, blockages (animal nests are common in Ottawa), and debris. Essential for wood-burning fireplaces — c...
Wood-burning fireplace maintenance: Annual cleaning is essential. Burn only seasoned hardwood (oak, maple, ash) — softwood and green wood create excessive creosote. Use a fireplace thermometer to maintain flue temperatures above 250°F, which burns off creosote before it accumulates. Gas fireplace maintenance: Annual inspection ($150–$250) checks the pilot light, thermocouple, gas valve, and venting. Gas fireplaces produce acidic condensation that can deteriorate chimney liners — stainless steel...
WETT certification: For any work involving wood-burning appliances, hire a WETT-certified professional. WETT certification ensures the technician understands fire safety standards, proper clearances, and installation requirements. Home insurance companies often require WETT inspection reports. Masonry expertise: For tuckpointing, crown repair, and chimney rebuilds, hire a mason with specific chimney experience. Chimney masonry requires different mortar types and techniques than regular brickwor...
Chimney cleaning costs $150–$300. Cap installation costs $200–$500. Tuckpointing costs $450–$2,400. Flue relining costs $2,000–$7,000. Partial rebuild costs $3,000–$10,000. Full rebuild costs $10,000–$25,000+.
Annually for any chimney in active use (wood-burning, gas fireplace, furnace venting). Level 1 visual inspections cost $150–$300. Level 2 camera inspections ($300–$600) are required when selling a home or after a chimney fire.
Yes, if you have a wood-burning fireplace or stove. Home insurance companies in Ottawa require WETT inspection reports to provide coverage for homes with wood-burning appliances. WETT certification is not required for gas fireplaces.
Physically yes, but it's not recommended. Professional chimney sweeps have the equipment to thoroughly clean and inspect the flue, identify problems (cracks, blockages, creosote levels), and ensure safe operation. The $150–$300 cost is minimal compared to the fire risk of improper maintenance.
