Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Cap & Crown Across Harrison
A chimney cap and crown in Harrison typically costs $450 to $1,300 when the crown needs repair and a cap needs replacement, and most jobs are completed in a single visit. If the crown has failed and water is getting behind the brick, the work moves into rebuild territory at $1,400 to $2,600. We’ve been doing this work in Harrison long enough to know that the village’s 1920s-to-1950s brick colonials and Tudors have a particular failure pattern, and it usually shows up at the top of the chimney first. Call (914) 537-6479 and Wendell or one of his crew will walk you through what you’re seeing before a single tool comes off the truck.
Why Top Hat Chimney Is Harrison’s Preferred Chimney Cap & Crown Company
Wendell Pike put his name on this company in 1999, and he has been looking down Harrison chimney stacks ever since. The folks who call us from streets like Oakland Avenue, Halstead Avenue, and the winding lanes around Purchase aren’t calling a call center. They’re calling a local owner-operator who answers the phone and shows up in a uniform with a background check already on file.
Harrison homeowners tell us the same thing over and over: a national chain sent someone who quoted one price from a desk and a different number at the front door. That doesn’t happen here. The price you hear on the phone is the number on the invoice, before we touch a single brick. And every job, cap or crown, gets the 90-Day Done Right Promise in writing. If it’s not right, one call brings Wendell back at no additional cost.
We’re not new to Harrison. We know the difference between a chimney in the village proper and one on a three-acre Purchase estate, and we schedule for both without treating either one like a number. Response time to Harrison is usually same-week, often sooner when the weather has been doing what Westchester winters do.
Our Chimney Cap & Crown Services in Harrison
Cap Installation
Most Harrison homes we visit either have no cap at all or a rusted box-store cap that stopped doing its job years ago. An uncapped flue in a village colonial lets rain fall straight down an abandoned oil furnace flue, and that water sits there and works its way through the masonry during every freeze-thaw cycle. We size the right cap for each flue, because a cap that’s too small chokes the draft and one that’s too big doesn’t keep the weather out.

Cap Replacement
When wind off the Long Island Sound has been beating on a galvanized cap for fifteen years, replacement isn’t optional; it’s overdue. We stock quality caps in standard sizes and can have custom stainless or copper pieces fabricated locally, so a Harrison homeowner isn’t waiting three weeks on a backorder. If your existing cap is salvageable, we’ll tell you that plainly and not sell you something you don’t need.

Crown Repair
This is the work Harrison asks us about most often, and for good reason. The mortar crowns on 1920s-to-1950s brick chimneys are original, and after decades of freeze-thaw cycling they crack, spall, and start letting water into the stack. We cut out the loose material, re-form the crown with a proper overhang and drip edge, and leave you with a crown that sheds water instead of absorbing it.

Crown Coating
A full crown rebuild isn’t always necessary. When the crown is intact but the surface is porous and starting to erode, a Gelco crown coat seals it against moisture and buys real years before major masonry work. We use this on Harrison homes where the crown is still structurally sound, because the honest answer is what matters. Your flue doesn’t care how the fire looks; it cares how it breathes.

Multi-Flue Cap
The older Harrison home with both a gas furnace flue and a wood-burning fireplace flue in the same brick stack is exactly the situation a multi-flue cap is built for. These caps cover the entire top of the chimney while allowing each flue to draft independently, and they solve the problem of a single cap that only covers one flue while the other collects water and creosote behind the scenes.

Custom Cap
Some Harrison chimneys don’t fit a stock size, especially on larger Purchase properties with wide brick stacks and unusual flue spacing. We measure, spec the cap in stainless or copper, and have it built to match the masonry. It costs more than an off-the-shelf cap, but on an architectural chimney it’s the only kind that actually works and looks like it belongs there.

Trusted Brands We Service in Harrison
When we install a cap or re-coat a crown in Harrison, we’re putting our name on the work, so we only use materials we’d put on our own chimneys. That means HeatShield for flue repair, Gelco for crown and masonry coatings, and Copperfield caps when the job calls for a multi-flue or custom piece. We keep the common sizes and parts on hand for Harrison service calls, so the follow-up visit is quick when you need it. If you have a chimney that was worked on by another company and you’re not sure what’s up there, we’ll give you a free second opinion on any written estimate.
Common Chimney Cap & Crown Problems We See in Harrison Homes
- Uncapped multi-flue chimneys on village colonials. The original oil furnace flue gets abandoned after an oil-to-gas conversion, and no one ever capped it. Rain and snow go straight down, saturate the interior, and the freeze-thaw cycles in Harrison spall the crown from the inside out.
- Oversized gas flues creating condensation at the crown. A 1920s chimney sized for oil exhaust is too big for a modern gas furnace. The exhaust cools too quickly, condensation forms, and the moisture wicks up to the crown where it erodes mortar joints and pops brick faces off the top of the stack.
- Gas inserts with no proper cap on the original fireplace flue. We see this throughout Harrison’s village proper. The insert works fine, but the uncapped flue above it pulls downdrafts that push exhaust into the living room, and any occasional wood fire leaves creosote that nobody thinks to clean because the furnace is gas now. Once a year, burn or no burn. Chimneys break in the off-season too.
- Rusted or undersized caps from previous repairs. A cheap galvanized cap doesn’t survive the salt air that works its way up from the Sound, even as far inland as Harrison. And a cap sized for one flue on a multi-flue chimney leaves the other flue open to everything the sky drops on it.
Pricing for Chimney Cap & Crown in Harrison, NY
A standard single-flue cap installation in Harrison runs $350 to $550, including the cap and the work. A multi-flue cap on a colonial or Tudor with two or three flues runs $600 to $900. Crown coating with Gelco typically lands between $400 and $700 depending on crown size and condition. A full crown rebuild, where we cut out the failed mortar and re-form the crown with a proper overhang, runs $1,400 to $2,600 on a typical Harrison chimney. Custom caps on architectural stacks start around $800 and go up from there based on material and fabrication.
What changes these numbers is access. A chimney in the middle of a steep Purchase roof costs more than one on a village colonial with a low pitch. Steep-roof work carries real risk, and we price it with that in mind, using proper roof anchors and fall protection rather than hoping for the best. Call (914) 537-6479 for a firm quote. There’s no trip charge inside the county, and you get $40 off any repair over $200. Seniors and veterans always get 10% off.

FAQs - Chimney Cap & Crown in Harrison
Because the cleaning exposes what was already there. When we sweep a Harrison chimney, we’re on the roof looking at the crown, and the sweep itself often dislodges the loose mortar that was barely hanging on. That’s not the cleaning causing damage; it’s the cleaning revealing it. The camera footage and a plain-English verdict, every time, no exceptions. Call (914) 537-6479 for an exact quote and we’ll set a time.
Yes, and this is one of the most common setups in Harrison’s older homes. Each flue needs its own properly sized cap, or a multi-flue cap that covers both while letting each breathe. The gas flue and the wood flue draft differently, and a cap that’s wrong for one will cause problems for both. We’ll show you the camera footage before recommending anything.
A crown coat is a sealant layer we apply when the crown is intact but porous, and it runs $400 to $700. A full rebuild means cutting out the failed mortar and re-forming the crown, which runs $1,400 to $2,600. In Harrison, where freeze-thaw cycles work on crowns every winter, we see both. If the crown is cracked through or loose enough to wiggle with a finger, it’s rebuild time. If it’s solid but weathered, coating does the job. Call (914) 537-6479 and we’ll tell you which one you actually need, not which one costs more.
No, a cap alone won’t solve condensation in an oversized flue. The condensation happens because the exhaust cools too quickly in a chimney that was sized for oil. The real fix is lining the flue to match the new appliance, often with HeatShield or a properly sized liner. A cap helps keep rain out, but it doesn’t change the physics of exhaust temperature. If you’ve had an oil-to-gas conversion, the cap and crown are part of the picture, not the whole thing. Call (914) 537-6479 for a free estimate and we’ll look at the whole chimney.
If your cap only covers one flue, or if you can see the other flue from the ground, it’s wrong. A proper multi-flue cap spans the entire top of the chimney and has openings sized for each flue’s draft requirements. We measure each flue, check clearance and draft, and install a Copperfield multi-flue cap that fits the actual masonry, not whatever was cheapest at the hardware store. Call (914) 537-6479 and we’ll come measure.
