Your crown is your chimney's umbrella. When it cracks, water gets everywhere. We fix it the right way — with the right materials.
The crown is the concrete (or mortar) cap that sits on top of the chimney, sealing the brick from rain. Cheap crowns are just leftover mortar smoothed over the top — they crack in 5–10 years. Proper crowns are poured concrete with a drip edge that extends past the brick to direct water away from the masonry below.
We offer two repair tiers: crown sealing with a flexible elastomeric coating (extends life 10–15 years on a sound base), and full crown rebuild — chiseling off the old, forming and pouring a new concrete crown with proper overhang and drip edge. In Quincy's freeze-thaw climate, only the second option lasts.

Every chimney we touch in Quincy gets the same diagnostic discipline — find the actual cause, fix it properly, and document the work. Here's a closer look at the chimney crown repair problems we run into most.
If the crown is structurally sound (no major cracks, has overhang, no missing chunks), a two-coat elastomeric crown coating bonds to the concrete and extends life 10–15 years. We clean, prep, fill hairline cracks with flexible polymer, then apply the coating. Same-day job.
Crumbling crowns or those flush with the brick (no overhang) need a full recast. We chisel out the old crown, install rebar for tensile strength, form a proper 2-inch overhang with drip edge, and pour high-strength concrete. Cured under cover for 7 days — critical in coastal humidity.
A crown without a proper drip edge directs every drop of rainwater straight onto the brick below — that's how spalling starts. Our crown rebuilds always include the 2-inch overhang with a clean drip edge that throws water clear of the masonry.
Coastal Quincy crowns get hit by salt mist as well as freeze-thaw. We use UV-stable elastomeric coatings rated for marine exposure on shoreline homes. The cheaper coatings chalk and fail within 5 years on the coast — we don't install them.
Four clear steps — no vague pricing, no surprise add-ons, no rushed work.
We inspect the existing crown for crack patterns, depth, and whether it has a proper overhang. We recommend seal-only vs full rebuild based on what we find.
Cleaning, hairline crack filling with flexible polymer, two-coat elastomeric crown coating bonded to the concrete. 10–15 year service life on a sound base.
Chisel-out of old crown, install rebar where appropriate, form for proper 2-inch overhang, pour high-strength concrete, finish with drip edge. Cures for 7 days under cover.

Crown sealing: $349–$489 flat rate, typical single-flue. Full crown rebuild: $749–$1,400 depending on chimney width and access. Combined crown + cap install: $1,100–$1,900 (better value than scheduling separately). Severe cases with rotted top courses get quoted with the brick repair included.
After a crown rebuild, no maintenance is needed for 10–15 years. After crown sealing, plan to re-coat every 8–10 years on inland homes, 6–8 years on coastal homes. Pair with brick waterproofing on the courses below the crown — they're the next failure point if left exposed.
