Booked a sweep and WETT inspection before winter. Crew arrived on time, laid down drop cloths, and walked me through the report photo by photo. Fixed pricing, no upsell — exactly what was quoted.

What Toronto homeowners say about damper repair
5.0 / 5 · based on verified customer reviews
Cracked clay liner in our 1962 fireplace. They installed a stainless liner and new cap in one day and the draft is perfect. Warranty paperwork emailed the same evening.
— David R.
Called for a raccoon in the flue. They removed it humanely, sanitized the smoke chamber, and installed a stainless cap. Fair price, no drama, and they even followed up a week later.
— Priya S.
Tuckpointing on a 90-year-old chimney. The mortar colour match is genuinely impressive — you can't tell where the new work starts. Careful, tidy crew.
— Mark T.
Full rebuild above the roofline after storm damage. Insurance-approved quote, permits handled, and finished in four days. Ten-year structural warranty in writing.
— Jennifer L.
Annual gas fireplace service and CO check. Tech spent 90 minutes doing it properly — cleaned burners, tested for leaks, calibrated the pilot. First time in years the flame looks right.
— Andrew K.
