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 between $350 and $1,400 depending on whether you need a simple cap replacement or a full custom multi-flue crown rebuild. Most Harrison homes built before 1945 still run original clay tile flues, and that changes the job entirely: you can’t just slap a cap on a compromised liner and expect it to hold. Wendell Pike and his crew have worked this town long enough to know which streets in the village core hide original single-wythe chimneys and which Purchase estates stack four flues in one stack. Call (914) 685-6096 and we’ll give you a straight answer before any tool comes off the truck.
Why Top Hat Chimney Is Harrison’s Preferred Chimney Cap & Crown Company
We’re not a franchise that rotated into Westchester last spring. Top Hat Chimney has been owner-operated since 1999, with a published address and license number. Wendell puts his name on every job in Harrison because he runs into you again on Saturday at the hardware store or the farmers market. That changes how the work gets done.
Harrison pulls us in two directions at once, and we’re comfortable in both. The pre-WWII village core is dense with 1920s and 1930s brick colonials and Cape Cods that still have original, unlined or under-lined chimneys. Head east past I-684 into Purchase and you’re looking at mid-century estates on two-acre wooded lots, where a single exterior chimney stack can carry four or more flues. A cap job in one part of Harrison is a $400 repair. In another, it’s a multi-flue inspection project that requires camera work on every flue before anyone touches a cap. Few companies do both well. We do both every week.
Every completed job in Harrison carries the 90-Day Done Right Promise in writing. If something isn’t right, one call brings Wendell back. No fine print, no voicemail maze. Phones are answered by a live person around the clock, and it may well be Wendell himself picking up at 2 a.m.
Our Chimney Cap & Crown Services in Harrison
Cap Installation
A properly sized cap keeps rain, squirrels, raccoons and birds out of the flue while still letting the chimney breathe. In Harrison’s village neighborhoods, we see a lot of original chimneys that never had caps at all. Homeowners assume the flue is sealed because the chimney looks fine from the lawn. It isn’t. We stock standard sizes from Olympia Chimney and Famco, so most Harrison cap installations are done in one visit.
Cap Replacement
Cap replacement in Harrison often means correcting a mistake someone else made. We routinely remove undersized caps that were installed by a handyman or a roofing crew, caps that sit so tight against the flue tile that they choke off draft and push smoke back into the house. If the old cap is rusting through at the screen or the mesh is clogged, it’s time. We size the replacement to the flue, not the opening, and use stainless or copper depending on what’s already on the roof.
Crown Repair
The crown is the concrete slab that caps the chimney structure, not the flue opening inside it. On Harrison’s 1920s and 1930s brick colonials, crowns are usually thin, poorly sloped, and unreinforced. Freeze-thaw cycles cross the 32-degree line dozens of times each Westchester winter, and every cycle widens hairline cracks in those old crowns. A cracked crown lets water into the brick, and by spring you’ve got spalled faces and loose mortar. Crown repair means removing failed material, building proper slope away from the flue, and sometimes adding a drip edge.
Crown Coating
Crown coating gets sold hard by national outfits as a $200 fix-it-all. In Harrison it’s rarely that simple. A crown coating bonds well to structurally sound concrete, but it won’t adhere to decades-old masonry that’s already crumbling. On village colonials with original crowns, we typically grind out failed mortar and repair cracks before any coating goes on. Gelco makes a crown coat we trust for this, but only after the substrate is right. If we tell you coating won’t hold, it’s because the camera didn’t lie.
Multi-Flue Cap
This is the purchase estate specialty. A single exterior stack in Purchase can carry four or five flues: one active fireplace, one decommissioned boiler, a kitchen exhaust, and two the owners never knew existed. Multi-flue caps from Copperfield or Gelco cover the full crown and have individual screened openings per flue. The real work isn’t the cap. It’s mapping every flue to its firebox and damper first. We don’t cap what we haven’t inspected.
Trusted Brands We Service in Harrison
We install and service products from Gelco, Copperfield, Olympia Chimney, and Famco. These aren’t box-store brands; they’re what chimney contractors actually run when they’re putting their own name on the work. For Harrison customers, that means replacement parts don’t sit in a warehouse in another state. We keep common cap sizes and crown materials on the truck, so most repairs don’t need a second visit.
Common Chimney Cap & Crown Problems We See in Harrison Homes
- Original clay tile liners with a new cap on top. On 1920s-1940s village colonials, the original clay tile is often cracked or missing entirely. A cap that seals the top can trap moisture inside, accelerating spalling instead of preventing it. The liner situation has to be known before the cap goes on.
- Unknown flues in Purchase estate stacks. Homeowners with four or five flues in one chimney frequently don’t know which are active and which are abandoned. A missing or undersized cap on a disconnected flue lets water and animals into the masonry while the main fireplaces keep working fine. The quiet damage is the expensive kind.
- Freeze-thaw crown failure on older brick. Westchester winters cross the freezing line dozens of times per season. Older unreinforced crowns don’t tolerate that. The face of the crown spalls off in sheets, and water works into the stack below the roofline before anyone notices from the ground.
- Creosote buildup from burning local fallen hardwood. The heavily wooded character of Purchase and the surrounding residential areas means well-meaning homeowners burn wood they felled themselves last fall. Unseasoned hardwood burns cool and dirty. We see first-degree creosote turn to third-degree glaze faster in Purchase than in more open parts of Westchester.

FAQs - Chimney Cap & Crown in Harrison
How many flues does a typical Purchase estate chimney in Harrison actually have, and why does that matter for a cap?
A single exterior chimney stack on a mid-century Purchase estate commonly carries three to five flues, and homeowners are frequently aware of only one or two of them. Two might serve active fireplaces, one belongs to a decommissioned boiler, and the rest are abandoned or never were connected. A cap decision only makes sense once every flue is identified and camera-inspected, because a disconnected flue left uncapped lets water into the masonry quietly for years. Call (914) 685-6096 and we’ll map every flue before recommending any cap work.
My Harrison colonial was built in 1930 and still has the original clay tile liner. Can I just add a chimney cap, or do I need a liner first?
If the original clay tile is cracked or missing, a cap alone can trap moisture and accelerate spalling inside the flue. The sequence matters. We camera the flue first. If the liner is intact enough to serve the appliance, a cap goes on and you’re done. If the liner is compromised, the cap install should usually wait until the flue is relined or resurfaced, and adding a cap as part of that job is straightforward. We’ll show you the footage and let you decide.
The crown on my Harrison chimney is cracked and I can see exposed brick below the cap. Is crown coating enough, or do I need a full crown repair?
Exposed brick below the cap usually means the crown has lost enough material that water is already getting into the stack, and a crown coating alone will not bond to crumbling, feathered old mortar. You’re looking at mechanical crown repair: removing the failed concrete, rebuilding the slope, adding a drip edge. Then coating becomes an option. We’ll camera from the flue side and show you exactly what the masonry looks like before we quote a dollar.
Why does creosote build up faster in Harrison’s Purchase neighborhood than in more open parts of Westchester?
Purchase is heavily wooded, and homeowners there routinely burn trees that came down on their own two acres. Wood felled one fall and burned the next winter is rarely seasoned enough, and wet or green hardwood burns cool, which drives creosote deposition hard. The same fireplace burning kiln-dried wood in a more open neighborhood won’t load up nearly as fast. In Purchase, a once-a-year sweep is a minimum, not a suggestion.
Can I put one large cap over a multi-flue chimney, or does each flue need its own cap?
Both options exist, and the right answer depends on what the flues actually do. A single full-width multi-flue cap covers the crown and has individual screened openings for each flue, but only works when all flues are mapped and the cap can be fabricated to match the existing spacing. An individually capped flue arrangement is simpler and often better when flue heights differ or one flue serves an appliance with different draft needs. For Harrison’s older stacks, we usually recommend individual caps unless the crown is being rebuilt anyway. Call (914) 685-6096 and we’ll walk through what makes sense for your chimney.
