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 Sellersville
Chimney cap and crown work in Sellersville typically runs $340-$980 for a standard cap replacement with crown sealing, and most jobs are finished in a single visit. The older the home, the more likely you’re dealing with a multi-flue stack that needs more than a trip to the hardware store can solve. Call (484) 600-2977 for an exact quote before booking.
We’ve worked the tight rows and stone facades of Sellersville long enough to know that what looks like a simple cap issue often traces back to a crown that’s been quietly failing for years. Wendell Pike and his crew show up in uniform, walk the roof with you if you want, and explain what they see in plain English. No pressure. No mystery.
Why Top Hat Chimney Is Sellersville’s Preferred Chimney Cap & Crown Company
Sellersville’s housing stock doesn’t forgive shortcuts. The pre-1920 stone and brick row homes along Main Street and around East Park Avenue share chimney stacks built for coal and wood, not the gas appliances now venting through them. That mismatch creates problems a franchise tech from out of town won’t recognize. Wendell has worked these flues since 1999, and he’ll tell you when a job can wait and when it can’t.
Every visit ends with camera footage and a plain-English verdict. That’s not a selling point - it’s how we’ve always done it. If you live on Chestnut Street or over near the creek, you’ll get the same straight answer. Our Chimney Cap & Crown work is backed by a 90-Day Done Right Promise in writing. If it’s not right, one call brings us back, no charge.
Response time to Sellersville is quick. We coordinate from our Philadelphia office, but crews serve the borough directly and know the parking realities of the side streets and alleys. Calls are answered by a live person, 24/7. It may well be Wendell himself picking up at 9 p.m. when you’re staring at a water stain on the ceiling.
Our Chimney Cap & Crown Services in Sellersville
Cap Installation
A properly sized cap keeps rain, birds, and leaves out of the flue. On Sellersville’s historic row homes, that measurement isn’t standard - flue tiles vary from 8×8 to 13×13, and sometimes they’re cracked on top. We measure each flue, not just the outside of the stack, and install a cap that actually fits. Famco and Copperfield caps are what we carry most often.
Cap Replacement
Rust perforation and animal damage are the usual reasons caps fail. On shared multi-flue stacks, a missing cap on one flue lets rain into adjacent flues your neighbors are using. That’s a Sellersville-specific problem most generic advice never mentions. We replace bad caps, match the existing setup where sensible, and let you know if a larger custom cap makes more sense for the whole stack.
Crown Repair
Freeze-thaw cycling through Bucks County winters spalls mortar joints and cracks crowns at a rate you don’t see in milder counties. A cracked crown lets water pool at the flue openings and drip down into the masonry. We rebuild crowns with proper slope so water sheds away, then coat them to prevent the same failure next spring.
Crown Coating
Gelco crown coating over repaired masonry gives old crowns another decade or more. It’s a smart middle step between patching and rebuilding. On Sellersville’s older stone chimneys, where the original mortar was mixed soft and sand-rich, coating seals the surface against the acidic condensation that oversized flues produce when gas appliances retrofit into coal-era stacks.

No running back and forth, no surprises on the invoice.
Common Chimney Cap & Crown Problems We See in Sellersville Homes
- Cross-contamination in shared stacks: A neighbor’s gas appliance vents into the same multi-flue chimney your fireplace uses. A cracked liner can push carbon monoxide onto your side without visible smoke. We check this on every inspection.
- Spalled clay tile crowns: The original 19th-century flue tiles in many Sellersville row homes were never upgraded for modern appliance output. Freeze-thaw cycles break them down, and the debris blocks the flue below.
- Missing caps on adjacent flues: One open flue in a multi-flue stack lets rain and squirrels into the whole structure. Moisture spreads through shared masonry, and you get the mold and staining even if your cap is fine.
- White staining at the crown joint: Oversized vintage masonry flues condense heavily when retrofitted for gas. Acidic byproducts leach through cap-to-crown joints and streak down the limestone and sandstone facades so common on East Park Avenue and Main Street.

FAQs - Chimney Cap & Crown in Sellersville
It can affect it directly. In a shared multi-flue stack, rain entering your neighbor’s open flue soaks into the common masonry, cools the flue gases, and weakens the draft on your side. Standing water in the adjacent flue also raises humidity inside the shared structure, which can make your logs hard to light and your fire smoky. If you smell damp or see water streaks on the chimney interior, call (484) 600-2977 and we’ll camera the whole stack, both sides.
Because the original mortar was mixed by hand, often with local sand and lime proportions that don’t stand up to repeated freeze-thaw cycling. Water gets into micro-cracks, freezes, and expands, spalling the crown surface within a decade. It’s not that the mason did bad work in 1890 - it’s that the material has a limit. We repair and coat crowns with Gelco to buy them meaningful time before a full rebuild is needed.
Usually not, and forcing one on is a mistake. Many of these stacks have three or more flues, each with different tile dimensions - some 8×8, some 9×13, some oval. A box-store cap either won’t seat or will blow off in the first storm. We fabricate custom multi-flue caps, often with Copperfield’s custom shop, sized to the actual tile layout of your specific stack. That’s the only way it stays put and works.
The white staining is efflorescence - mineral salts being pushed out of the masonry by water. On a Sellersville row home, it usually means the crown has failed and rainwater is soaking down through the brick. It can also come from acidic condensation when a chunky vintage flue vents a modern gas appliance. The cap and crown work together: if either fails, the stain comes back. We repair both in one visit and show you the camera footage before and after.
Yes. When gas exhaust vents into a shared flue, the liner condition matters more than the cap style. A cracked liner on their side lets combustion byproducts cross to your side. We inspect the full stack with a camera, check both flues, and recommend a cap configuration that maintains separation. If work is needed, the price is still upfront and the estimate is free. Call (484) 600-2977 to book it.
