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.

Why Top Hat Chimney Is Dobbs Ferry’s Preferred Chimney Cap & Crown Company
Wendell Pike founded Top Hat Chimney in 1999, and he’s been inside more chimneys in this village than he can count. We’re not a franchise that rotated in last spring. When you call, a live person picks up, not a call center. The number you hear on the phone for your Chimney Cap & Crown work is the number on the invoice, full stop, before a single tool comes off the truck.
Ask anyone on your street. The homes in Dobbs Ferry were built for coal, converted to oil, then converted again to gas, and too many of those conversions skipped the part where you reline the flue or replace the cap that hasn’t fit right since Roosevelt was in office. We know the difference between a chimney that needs work and one that just needs a cleaning, and we’ll tell you plainly. Every job comes with the 90-Day Done Right Promise in writing. If it’s not right, one call brings Wendell back, no charge.
Dobbs Ferry customers get a real arrival window and a call if we’re running late. Background-checked, uniformed techs. Free second opinion on any competing written estimate. $40 off any repair over $200. And a 10% discount always for seniors and veterans. That’s not a promotion. It’s how we’ve done business since 1999.
Our Chimney Cap & Crown Services in Dobbs Ferry
Cap Installation
A chimney without a cap in Dobbs Ferry is an open invitation for oak leaves, maple twigs, and moss to pile up inside your flue. We install stainless and copper caps sized to your actual flue dimensions, not whatever’s on the truck. For homes with multiple flues stacked side by side, we custom-fit a cap that covers all of them without choking the draft. Call (914) 537-6479 for a free estimate.
Cap Replacement
If your current cap is rusted through, missing the mesh screen, or too small for the flue, replacement is straightforward and usually done the same visit. In Dobbs Ferry, the damp river air accelerates rust on cheap galvanized caps. We stock copper and stainless options that hold up better. The cap pays for itself the first time a raccoon tries to move in and can’t.
Crown Repair
Your crown is the concrete slab on top of the chimney that sheds water. When it cracks, water gets into the brick below, and on the south-facing chimneys in Dobbs Ferry, freeze-thaw cycles do the rest. We repair crowns properly: clean out the loose material, fill the cracks, and reslope the surface so water runs off instead of pooling. Small cracks are often a same-day fix. A crown that’s been crumbling for years may need more work, and we’ll show you the camera footage so you can see exactly what’s there.
Crown Coating
Once the masonry work on the crown is done, we seal it with Gelco, a breathable waterproof coating made for exactly this purpose. It keeps the crown from absorbing river moisture and cracking again the next winter. The coating extends the life of the repair by years, especially on older Dobbs Ferry chimneys where the original mortar has turned to sand. We apply it after the crown has been repaired and sloped, then show you the result on camera.
Multi-Flue Cap
Many Dobbs Ferry chimneys have two or even three flues running through a single chimney stack, one for the furnace, one for the fireplace, sometimes one for an old coal chute. A single cap doesn’t cover the whole crown, and water gets in between. We fabricate and install full-width multi-flue caps that seal the entire top of the chimney. That’s the right fix for most of the older homes we see above Broadway.

Trusted Brands We Service in Dobbs Ferry
We install and service caps and crowns from Copperfield, DuraFlex, and Gelco. Copperfield makes the heavy-gauge copper and stainless caps we use on many of the multi-flue jobs in Dobbs Ferry. DuraFlex relining products come into play when the flue itself is compromised, and Gelco is our go-to crown coating. We keep common sizes in stock so we’re not waiting on a parts truck from three counties away. If your chimney needs a liner, we also work with HeatShield to reline flues without a full teardown. Call (914) 537-6479 and we’ll tell you what your chimney actually needs.
Common Chimney Cap & Crown Problems We See in Dobbs Ferry Homes
- Freeze-thaw spalling on south-facing crowns. The Hudson River’s damp microclimate cycles brick and mortar through freeze-thaw stress every winter, and south-facing sides take the worst of it. Crowns crack, then crumble, and water gets into the firebox before you notice anything on the roof.
- Missing or undersized caps on coal-era flues. Dobbs Ferry homes built between 1880 and 1930 were designed for coal, not gas. The flues were never relined, and the caps, if they exist at all, don’t fit the current venting. Debris piles in, draft suffers, and carbon monoxide has nowhere to go but back into the house.
- Organic debris from overhanging canopies. On the terraced streets above the Metro-North station, mature oaks and maples sit at or above chimney height. Leaves, twigs, and moss drop straight into uncapped flues. We’ve pulled two-gallon buckets of wet leaves out of flues that looked fine from the ground.
- Original mortar crowns eroding into grit. The mortar crowns on many Victorian chimneys in the village are over a century old. They’ve been crumbling slowly for years, and the grit washes down the flashing and stains the roof every time it rains. If you see sandy material in your gutters directly below the chimney, that’s your crown falling apart.

FAQs - Chimney Cap & Crown in Dobbs Ferry
Because most chimneys in Dobbs Ferry were built with multiple flues stacked side by side, one for the coal furnace, one for the fireplace, and sometimes a third for a kitchen range. A single cap only covers one flue, leaving the rest of the crown exposed to rain and debris. We see this every week on the older homes between Main Street and the river. The right fix is a full-width multi-flue cap that seals the entire top of the chimney. Call (914) 537-6479 for a free estimate, and we’ll show you exactly what’s on your roof.
Look for sandy grit in the gutters directly below your chimney, or for small pieces of mortar on the roof deck. That grit is your crown disintegrating. Spalling gets worse each freeze-thaw cycle, and in Dobbs Ferry’s river-humid winters, those cycles happen weekly. What starts as a small crack becomes an open channel for water into the brick inside a season or two. It’s urgent enough that you should call before the next hard freeze. Estimates are free.
Depends on the cause. If the smell is from leaves and twigs decomposing inside the flue, a properly fitted cap stops it immediately. If the smell is from a rusted-open damper or a cracked crown letting rain pool on the smoke shelf, the cap helps but the crown and damper need attention too. We’ll tell you which it is, with camera footage, before we recommend a single thing. Call (914) 537-6479 to set up a look.
Usually, yes. If the masonry underneath is still sound, we clean out the loose mortar, fill the cracks, reslope the surface so water drains properly, and coat it with Gelco. That’s a same-day repair in most cases. If the brick below the crown has started to break apart, the job gets bigger, and we’ll show you the camera footage so you can see why. You’ll never get a rebuild recommended based on a story you can’t verify.
Without a cap, rain, leaves, and whatever animal decides to nest inside all enter the flue. Wet creosote becomes acidic and eats through the flue liner. Blocked flues push carbon monoxide back into the living space. In an older Dobbs Ferry home with a coal-era flue that was never relined, that’s a genuine carbon monoxide risk, not a hypothetical. A missing cap is the cheapest repair we do, and it’s the one most often skipped. Call (914) 537-6479.
What Makes Dobbs Ferry Different from Ardsley or Irvington
In Dobbs Ferry, the steep terraced streets above the Metro-North station create a canopy of mature oaks and maples that sits at or above chimney-cap height. That’s not something you see in the more open, flat neighborhoods in nearby Ardsley or Irvington. Those overhanging branches cause chronic downdrafts and deposit leaves, twigs, and moss directly into flues. On a Queen Anne on Chestnut Street, our tech found a cracked crown and a missing cap on a coal-era flue now venting a gas furnace. Rain was pooling on the smoke shelf, the damper was rusted open, and the homeowners had been smelling damp fireplace every spring for years. We installed a custom Copperfield multi-flue cap and coated the crown with Gelco, then showed them the camera footage of the repaired surface before and after. That’s the kind of problem only a local chimney person sees coming. If your house is on a hillside street with tree cover, you’re more likely to need cap and crown work than your cousin down in the flat parts of town. Call (914) 537-6479 and we’ll take a look.
