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 cap replacement
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.
FAQ
Cap Replacement — common questions
How much does chimney cap replacement cost in Toronto?+
A standard stainless-steel chimney cap replacement in the GTA starts at $450 in 2026. Copper caps and multi-flue or oversized custom caps range from $650–$1,200. We quote fixed-price after a free inspection.
Can I just install a cap myself?+
Big-box caps are often the wrong size and use galvanized steel that rusts within a few seasons. A custom-fitted cap with proper fasteners and sealant protects your flue for decades and is the safer choice.
How do I know if my chimney cap needs replacing?+
Rust stains on the chimney, visible holes, a missing cap, or water/debris inside the firebox are all signs. Our free inspection confirms whether replacement or just resealing is needed.
Will a new cap fix my smoky fireplace?+
If downdrafts or wind are pushing smoke back into your home, a properly designed cap with wind-resistant baffles often solves the problem. We test draft before and after installation.
What materials do you offer?+
We stock 304 and 316 stainless-steel caps with black powder-coat or natural finishes, plus solid copper caps for heritage and high-end homes. All carry a lifetime warranty.
