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.

Chimney Crown Replacement
278 reviews 15-minute callback$50 OFF · FREE INSPECTION
The chimney crown is the sloped concrete slab on top of your chimney. When it cracks or spalls, water pours straight into your masonry and flue — accelerating brick decay, rusting the damper, and eventually causing a $10K+ rebuild. We remove the failed crown and pour a properly reinforced, drip-edged replacement rated for Ontario freeze-thaw cycles.

What Toronto homeowners say about crown 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
Crown Replacement — common questions
How much does chimney crown replacement cost in Toronto?+
A full crown rebuild in the GTA typically costs $900–$2,200 in 2026, depending on chimney size and access. A surface-only crown seal (for hairline cracks) starts at $350. We quote fixed-price after a free inspection.
Crown seal vs. full crown replacement — which do I need?+
A crown seal is a surface-applied elastomeric coat and buys 5–10 years on a structurally sound crown with hairline cracks. Full replacement is required when the crown has structural cracks, spalling, missing overhang, or no drip edge. Our free inspection tells you which one your chimney actually needs.
How long does the crown replacement take?+
Most single-chimney crown rebuilds are done in one day (4–8 hours on site), plus 24–48 hours cure time before your first fire.
Is it covered by home insurance?+
Sudden damage (a storm, a tree strike) is typically covered. Wear-and-tear failure is not. We provide detailed cause-of-failure documentation with every job to support your claim.
What material do you use?+
A properly proportioned Portland-cement crown mix with steel rebar reinforcement, a 2-inch overhang with drip edge, and a Type-S mortar bond breaker between the crown and flue tile. Finished with a 10-year siloxane sealer.
