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.

AfterFast, Reliable Chimney Cap & Crown Across Airmont
A chimney cap and crown in Airmont do more than keep rain out. The cap controls draft, and the crown is the concrete shoulder that sheds water before it can soak into your brick and mortar. In Airmont, where cold air rolls off the Ramapo ridgeline and freeze-thaw cycles chew through old masonry, a worn crown or a flat, undersized cap is the most common cause of smoking fireplaces, water stains, and brick that starts to spall. We fix both, and we show you camera footage of what’s actually wrong before we recommend a thing. Call (845) 599-0832 for an estimate.
Why Top Hat Chimney Is Airmont’s Preferred Chimney Cap & Crown Company
Wendell Pike started Top Hat Chimney in 1999, and he still answers the phone. When you call about a cap or crown in Airmont, you’re talking to the owner, not a call center. Wendell has worked Rockland County for over 29 years and has been inside more Airmont chimneys than he can count. That matters here. Airmont’s chimneys are not like chimneys in Spring Valley or Nanuet. The hillside streets near the Ramapo Mountains get terrain-driven downdrafts that flatland towns never see, and a cap that works fine four miles east on Route 59 can fail completely on a colonial up by the ridgeline. Our Chimney Cap & Crown work accounts for that difference.
Our Airmont customers tell us the same thing: the last company sent a stranger, changed the price at the door, and vanished when the fireplace still smoked. We do not operate that way. The price Wendell quotes on the phone is the price on the invoice. Our crew arrives in uniform, background-checked, and we give you a real arrival window. If it slips, we call. And every job carries the 90-Day Done Right Promise in writing. One call brings us back at no cost if it is not right.
Our Chimney Cap & Crown Services in Airmont
Here is what we actually do for Airmont homes. Each of these starts with a camera inspection so you can see the problem with your own eyes before you spend a dollar.
Cap Installation
A new cap is not a one-size-fits-all purchase. On Airmont’s hillside streets north of the Ramapo ridgeline, we routinely install high-draft caps that pull smoke up and out instead of letting mountain air push it back down. For standard colonials and split-levels in flatter parts of Airmont, a basic stainless cap sized to the flue tile is usually enough. We tell you which one you actually need and why.
Cap Replacement
Caps rust, bend, blow off, or simply never fit right in the first place. Airmont’s slightly elevated position means more precipitation than lower Hudson Valley towns, and a cheap galvanized cap with no screen becomes a rust problem in five years. We replace with stainless or copper, always sized and measured to your flue, never a box-store universal that leaves gaps.
Crown Repair
The chimney crown is the concrete slab across the top of the masonry. On Airmont homes built in the 1960s through 1980s, the original crowns are cracking and eroding. Hairline cracks let water in, and one hard Rockland County winter turns hairline into structural. We cut out damaged sections, re-form the crown with the correct overhang, and re-seal. A proper crown should shed water 2 to 3 inches beyond the brick, not drip it down the face.
Crown Coating
When the crown is still sound enough to save, we apply a waterproof coating that bridges microcracks and keeps freeze-thaw damage from starting. For Airmont’s older chimneys, this is often the single best dollar-for-dollar repair we can do. If the coating is done early enough, it postpones a full crown rebuild for years. We use HeatShield and Gelco products because they hold up to the wet, cold cycles we get in Rockland County.

Trusted Brands We Service in Airmont
We install and service caps, dampers, and crown products from Olympia Chimney, Famco, HeatShield, and Gelco. That is not a name-drop list.

You get real parts with real manufacturers behind them, not the cheapest thing that fits.
Common Chimney Cap & Crown Problems We See in Airmont Homes
- Cracked clay flue tiles. Airmont’s colonials, split-levels, and cape cods are 40 to 60 years old. The original clay tile flues crack from heat and age. Moisture and creosote migrate through those cracks into the surrounding masonry, and a basic sweep never flags it.
- Eroding mortar joints on original crowns. Freeze-thaw cycling in Rockland County is aggressive. Water gets into a hairline crown crack, freezes, expands, and spalls the mortar. By the time you see a brick chip in the yard, the crown has been failing for years.
- Smoking fireplaces on hillside streets. Cold air pushing down from the Ramapo Mountains creates negative pressure in the flue. A fireplace that only smokes when the wind blows from the ridges is not a cleaning problem. It is a draft problem, and it needs a high-draft cap, not another brushing.
- Gas appliances venting into unlined flues. Modern gas furnaces and water heaters produce high volumes of moisture. When they vent into a clay-tile flue never designed for that exhaust, the excess moisture attacks the crown and upper brick. This is a camera-diagnosed repair scenario, not a guess.

FAQs - Chimney Cap & Crown in Airmont
Why do Airmont homeowners on hillside streets often need a different chimney cap than neighbors in Spring Valley?
Because Airmont sits directly at the foot of the Ramapo Mountains, and cold, dense air rolls down the ridgeline and pushes into flues on north-facing streets. That terrain-driven downdraft creates negative pressure that a standard cap cannot overcome. Spring Valley is flat. Airmont is not. Homeowners up near the mountain often need a high-draft chimney cap to stop backdrafting, while a flatland home four miles away does fine with a basic rain cap. If your fireplace only smokes when the wind comes from the ridges, that is the tell. Call (845) 599-0832 and we will test your draft before recommending anything.
Does a chimney cap and crown repair stop water damage in Airmont’s older colonials even if the flue is unlined?
It stops the damage that comes from above: rain, snow, and freeze-thaw water entry through the crown and cap. It does not fix moisture problems inside an unlined flue from gas appliance exhaust. If your colonial still has an unlined flue venting a modern furnace, the interior moisture will keep attacking the masonry even after we seal the crown. We will show you that on camera and tell you plainly if a liner is needed. We will also tell you if the cap and crown work can safely proceed without one. The answer is usually yes for now, but you should know what is coming. Call (845) 599-0832 for an honest assessment.
How does Airmont’s freeze-thaw cycle affect chimney crowns on 1960s-1980s homes?
Airmont captures marginally heavier precipitation than lower Hudson Valley towns because of its elevated, mountain-adjacent position. That extra moisture, combined with sustained Rockland County cold, means any crack in a crown fills with water, freezes, expands, and widens the crack. Repeat that 40 times in a winter and a hairline fracture becomes a broken crown. Homes built between 1960 and 1980 are at the worst stage: the original crowns are 40 to 60 years old, and they have been through decades of this. Crown coating early stops the cycle cheaply. Crown repair later costs more. Either way, we can show you the current state of your crown on camera before you decide.
Can a chimney cap fix a fireplace that smokes only when the wind blows from the Ramapo Mountains?
Yes. That exact situation is one we see on Airmont’s hillside streets. Cold air sweeping down the Ramapo ridgeline hits the top of the chimney and pushes down the flue. A standard cap does nothing for that because it is designed to keep rain out, not to manage draft. A high-draft cap changes the airflow dynamics at the flue termination and pulls smoke up even when mountain air presses down. On a colonial near the northern hillside streets by the Ramapo ridgeline, our crew found a smoking fireplace that two previous cleanings had not improved. Camera inspection showed only first-degree creosote, but a draft test confirmed negative pressure on the flue. We installed a high-draft Olympia Chimney cap and sealed the crown, and the backdraft stopped. If your fireplace only misbehaves when the wind comes from the mountains, call (845) 599-0832. This is a draft problem, and it is fixable.
Why do you insist on camera inspection before recommending cap or crown work in Airmont?
Because you should not have to take anyone’s word for it. We push a camera down the flue and put the footage in front of you before we quote a single dollar of cap or crown work. On Airmont’s older chimneys, the difference between a simple crown coating and a full rebuild is often visible only on camera. Cracked clay tile segments, failed mortar joints, negative pressure zones from the ridgeline: these are not guesses. We show you what we see, explain it in plain English, and let you decide. No camera, no recommendation. That is the rule. Call (845) 599-0832 and see for yourself.
