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 Sellersville’s Preferred Chimney Repair Company
Wendell Pike has owned and operated Top Hat Chimney since 1999. That’s not a tagline. That’s a quarter century of showing up at somebody’s door in uniform, leaving the site cleaner than he found it, and then running into that same person at the Sellersville post office on Tuesday. People in Sellersville don’t hire us because a marketing budget told them to. They hire us because their neighbor on Diamond Street said, “Call the Top Hat guy.” Ask anyone on your street. The name gets passed around because the work holds up.
When you call us from Sellersville, a live person answers. Not a menu tree, not a call center. It may well be Wendell himself picking up. He’ll give you a straight number before a single tool comes off the truck, and that number is the number on the invoice. No bait quote, no surprise line item at the end. We’ve built our whole reputation in upper Bucks County on that one habit, and it’s the habit the national outfits can’t seem to replicate no matter how many times they change their logo.
We carry a published address and license number. Wendell puts his name on every job. That matters when you’re paying someone to climb onto a Victorian roof and rebuild a chimney that outlived your grandparents. You get background-checked, uniformed technicians who show up with a real arrival window, and if that window slips, you get a phone call. The 90-Day Done Right Promise is stamped on every single estimate and invoice, in writing, because we’d rather be held to it than hide behind fine print.
Our Chimney Repair Services in Sellersville
Mortar Repointing
Sellersville’s freeze-thaw cycles are the harshest in upper Bucks County because the borough sits inland, away from the Delaware River valley’s temperature moderation. Each winter, water sneaks into hairline cracks, freezes, expands, and pries those old mortar joints open a little wider. Repointing replaces that crumbling mortar with fresh, correctly matched mortar before the brick itself starts to break apart. On the borough’s rowhouses, a typical repointing job runs $450 to $1,200 depending on how many courses need work.

Spalling Brick Repair
Spalling is what happens when water gets behind the brick face and freezes, popping the surface off in flakes and shards. The soft, hand-fired brick in Sellersville’s mill-era housing stock is especially vulnerable after a century or more of that cycle. You’ll see it most often on chimney faces that get the brunt of the winter wind, like the exposed gable ends near Main Street hill. We remove the damaged brick, replace with matched salvaged or new brick rated for exterior masonry, and repoint around it. Spalling repair on a Sellersville chimney typically runs $600 to $1,800.

Chimney Waterproofing
Brick is porous. It always has been. The old clay brick in Sellersville soaks up rainwater like a sponge, and every freeze pushes a little more of the face off. A proper vapor-permeable waterproofing treatment, like the Gelco products we apply, stops water from getting in while still letting the masonry breathe. That matters a lot on chimneys that have already been repointed or rebuilt. Expect to spend $350 to $800 to waterproof a Sellersville chimney, and it’s the single best thing you can do after any repair to keep the new work from failing early.

Flashing Repair
Flashing is the sheet metal where the chimney meets the roof line, and in Sellersville it has been leaking quietly into attics for as long as these houses have had asphalt shingles. Old flashing rusts, lifts, and separates. Rain and snow push down through the gap. You won’t see it from the street, but water stains on the ceiling near the fireplace or a musty smell in the upstairs closet are usually the giveaway. Replacing flashing on a borough rowhouse or Victorian runs $400 to $900, and it’s one of those repairs that looks small but prevents thousands in framing and plaster damage if it’s caught late.

Trusted Brands We Service in Sellersville
We install and service liner systems from HeatShield, Gelco, Olympus Chimney, and Famco. On Sellersville jobs, the brand matters less than the fit, and we’ll tell you plainly which one suits your chimney. A coal-era flue being relined for a woodstove needs something different than a Victorian chimney being waterproofed after a crown rebuild. We stock parts locally so we’re not waiting on a UPS truck to finish a job that started Monday morning. If your chimney has a liner, cap, or crown from a brand we don’t recognize, we’ll still fix it correctly and source what’s needed. But if it’s one of those four, we’re ready same week.
Common Chimney Repair Problems We See in Sellersville Homes
- Clay tile liners cracking from gas-vent condensation. Your great-grandparents burned coal. The flue was sized for coal exhaust. Modern gas appliances vent cooler, moister exhaust, which condenses inside the old clay tiles and breaks them down from the inside out. We see this in nearly every Sellersville rowhouse chimney we scope.
- Mortar joints widening from freeze-thaw. Inland Bucks County gets sharper temperature swings than the river towns, and your mortar is paying for it. Once the joint opens past a quarter inch, water is getting in and doing damage you can’t see from the ground.
- Poor draft in coal-era flues adapted for gas. A flue built for a coal fire is oversized for a gas appliance, and oversized flues draft badly. When you add a woodstove insert or start burning wood again, that same flue accumulates creosote far faster than a properly sized modern liner would. First-degree creosote is a brush job. Third-degree is a glaze. Catch it early.
- Spalling on the soft brick of mill-era rowhouses. That brick was made locally, fired in a coal kiln, and it’s softer than anything made today. A hundred plus winters later, the face is giving out. It’s repairable if you get to it before the chimney loses its structural shadow.

FAQs - Chimney Repair in Sellersville
Because the flues were built for coal, not gas. The original clay tile liners are a century old, and after decades of gas-vent condensation eating at the tile from inside, they’re cracked and spalling in ways a brush will never fix. In Sellersville specifically, the borough’s pre-1940 housing stock makes this the rule, not the exception. When we scope one of these flues and show you the footage, you’ll see the missing chunks yourself. Relining with a system like HeatShield or DuraFlex fixes the draft and the safety problem in one job. Call (484) 603-6713 for a camera scope and a straight answer about whether yours is one of them.
Eventuelt, they won’t. The inland freeze-thaw cycling in upper Bucks County is tougher on masonry than the milder river valley weather. Mortar joints widen a little every winter. A small spalled patch grows. The key is to catch it while it’s cheap to fix. Repointing a few courses is $225 and change. Rebuilding a chimney that got ignored is thousands. We’ll give you an honest assessment and tell you plainly if the work can wait a season. Call (484) 603-6713 and we’ll take a look before the next hard freeze.
Get the flue scoped before you light one match. Those coal-era flues are oversized for gas, and oversized flues draft poorly. When you switch back to wood, the draft fails to pull the smoke and the creosote glazes the inside of the old tile far faster than a properly sized modern liner ever would. In a single burning season, a Sellersville homeowner can go from clean tile to third-degree glazing without ever seeing it from the hearth. That’s a chimney fire waiting to happen. Once a year, burn or no burn. Start with the camera. Call (484) 603-6713 and we’ll show you what the inside of your flue actually looks like, then give you a relining or rebuilding plan that fits the fire you want to burn.
No, and we’ll prove it. Nothing gets recommended without camera evidence you can watch alongside the sweep. If we tell you a liner needs replacement, we’ll show you the video of the cracked tile. If we tell you a flue can wait another season, we’ll say it out loud and put it in writing. The camera footage and a plain-English verdict, every time, no exceptions. We’ve never had to upsell a repair in Sellersville, because the old chimneys in this borough tend to make the case for themselves. If another company gave you a written estimate that doesn’t match what you’re seeing, call (484) 603-6713 for a free second opinion.
The brick was made here, fired here, and it’s soft by modern standards. Then it sat through a hundred and twenty winters of the borough’s inland freeze-thaw cycles. Water gets behind the brick face, freezes, expands, and pops off the surface in flakes. On the mill-era rowhouses near Main Street, it’s a pattern we see weekly. The fix is removing the damaged brick, replacing it with matched stock, and repointing around it, and it runs $600 to $1,800 depending on how far the damage has spread. The earlier you catch it, the smaller the repair. Call (484) 603-6713 and we’ll tell you straight whether your spalling is cosmetic or structural.
