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.

We’ve been working on Sellersville chimneys for decades. The borough’s tight rowhome blocks around Main and Church Streets, the old mill-worker cottages off Walnut Street, and the scattered Bucks County farmsteads out toward Ridge Road - each has a different chimney story, and most of them weren’t built for the appliances they’re running today. That’s why our Chimney Cap & Crown team starts every job with a Level 2 camera inspection. You see the photos. We give you a plain-English verdict. Then you decide.
A bad crown or missing cap in Sellersville isn’t a cosmetic issue. Upper Bucks County’s 25-30 inches of annual snow and brutal freeze-thaw cycles turn small cracks into spalled brick by spring. And in a borough where many chimneys were built for coal heat and now vent oil or gas appliances, moisture problems are compounded by flues that stay too cold and too wet. We document what we find. We show you before we recommend anything. That’s how we’ve operated for over 42 years.
Why Hearthstone Chimney Co. Is Sellersville’s Preferred Chimney Cap & Crown Company
Sellersville homeowners call us because we treat their chimneys like the structural systems they are, not sales opportunities. Our technicians are background-checked, uniformed, and trained to explain what they find without pushing unnecessary work. Most cap and crown jobs in Sellersville are finished in one visit with no-hassle upfront pricing - the number on the estimate is the number on the invoice.
Our 90-Day Done Right Promise covers every job in writing. If it’s not right, we make it right. No paperwork to dig up, no arguing. We answer our phones with a live person 24 hours a day, 7 days a week - not a voicemail tree, not a callback queue. When you’re staring at a water stain on your bedroom ceiling and wondering if your chimney crown is the culprit, that matters.
We know Sellersville’s housing stock. The pre-1940 brick rowhomes with their original clay-tile liners. The converted mill cottages with unlined flues nobody’s inspected in thirty years. The 18th-century stone farmhouses with multi-flue stacks that have never seen a camera. That local knowledge changes what we look for, what we recommend, and how we do the work.
Our Chimney Cap & Crown Services in Sellersville
Cap Installation
New cap installation in Sellersville runs $280-$550 for standard single-flue models, $450-$850 for multi-flue or custom-fit caps on larger or shared stacks. We size caps to your flue and your chimney’s exposure - a cap that works on a detached suburban ranch will fail on a Sellersville rowhome where wind whips down the alley between Main and Church Streets. Our techs measure on-site and install from stock, so you’re not waiting weeks for parts.
Cap Replacement
We replace rusted, wind-damaged, or improperly sized caps throughout Sellersville. A common find: a homeowner installed a big-box store cap that doesn’t actually cover the flue opening, or a “universal” fit that blew off in the first winter storm. We fabricate and install caps from Gelco and Olympia Chimney that match your flue count, size, and the local wind exposure. Replacement typically costs $340-$680 depending on access and whether the flue needs repair underneath.
Crown Repair
Crown repair is our most frequent Sellersville call from March through May, after freeze-thaw damage reveals itself. A cracked crown on a pre-1940 brick chimney lets meltwater wick straight into the mortar joints and down the flue. We grind out failed crown material, pour new concrete or apply specialized crown repair compound, and slope it to shed water properly. Typical range: $450-$950. Severe cases where the crown has separated from the brick course below run $800-$1,200.
Crown Coating
For crowns with surface cracking but sound structure, we apply professional-grade flexible crown coating - a waterproof membrane that bridges hairline cracks and stops water penetration without full rebuild. This is a smart option for Sellersville homeowners with solid crowns that just haven’t been maintained. Runs $280-$450. We only recommend coating after camera inspection confirms the underlying masonry is sound. No exceptions.
Multi-Flue Cap
Multi-flue caps are essential for many Sellersville properties - especially the shared party-wall chimneys in the borough’s historic rowhome blocks. A single cap covering multiple flues prevents water intrusion across the entire crown surface and blocks debris from every flue served by the stack. We size and install multi-flue caps from Gelco and Famco, fabricated to your chimney’s exact dimensions. Typical cost: $550-$950 installed.
Custom Cap
Odd-sized flues, decorative chimney pots, or heritage masonry that can’t accept standard hardware - we fabricate custom caps for these Sellersville chimneys. Copper, stainless, or powder-coated steel, sized and installed on-site. Custom work starts around $680 and ranges to $1,400+ for complex multi-flue or heritage installations. We show you the design before we build it.

Common Chimney Cap & Crown Problems We See in Sellersville Homes
- Freeze-thaw crown failure on pre-1940 brick. Sellersville’s original rowhomes and mill cottages were built with concrete crowns that weren’t designed for decades of upper Bucks County winters. Water enters hairline cracks, freezes, expands, and spalls the crown and the brick beneath it. By March, we’re seeing the damage.
- Oversized coal-era flues running modern low-output appliances. The original flue was built for a coal furnace or wood cookstove. Now it’s venting a 80% efficiency gas unit. The flue stays cold, condensation forms, and the crown and cap can’t keep up with the moisture load. Camera evidence separates real problems from scare tactics.
- Shared party-wall stacks with cross-contamination risk. In the rowhome blocks near Main and Church Streets, one chimney stack often serves two households. A failed cap or cracked crown on one side lets smoke, gases, and moisture migrate into the neighbor’s flue. Both owners need to know what condition their shared masonry is in.
- Efflorescence and interior liner cracking from valley humidity. Sellersville sits in a pocket near the Perkiomen Creek watershed where humidity stays elevated. That moisture accelerates deterioration in chimneys already stressed by cold, wet flue gases. White powder on your brick exterior is a warning sign.

FAQs - Chimney Cap & Crown in Sellersville
If your chimney serves more than one appliance or flue, a multi-flue cap covers the entire crown surface and protects every opening from water and debris. In Sellersville’s rowhome blocks, many chimneys vent a furnace and a water heater, or serve two households through a shared party-wall stack. A single-flue cap leaves the rest of the crown exposed. We measure your flue configuration on-site and size the cap accordingly. Call (610) 991-8179 for an exact quote - estimates are free.
Active failure shows as visible cracks that widen after winter, pooling water on the crown surface, pieces of concrete missing, or water stains on interior walls near the chimney stack. Age alone isn’t reason to rebuild. We run a Level 2 camera inspection and photograph the crown from the roof so you can see exactly what we’re seeing. Hairline cracking on a sound structure gets crown coating. Separation from the brick course or deep spalling means rebuild. You’ll know before we start. Call (610) 991-8179 to schedule.
Yes, and it’s one of the defining chimney problems in a historic borough like Sellersville. Coal burned hot and kept the flue dry. Modern gas furnaces produce lower-temperature exhaust that condenses in an oversized flue, creating chronic moisture that attacks mortar, liner, and crown from the inside. A new cap and crown help, but they can’t fix an improperly sized flue. We check liner condition with our camera before recommending any cap or crown work, and we’ll tell you plainly when the flue itself needs attention first. Call (610) 991-8179 for an inspection.
It can, and we’ve documented it in Sellersville rowhomes. We were called to a brick rowhome off Church Street where the owner smelled smoke in an upstairs bedroom whenever the neighbor’s oil furnace kicked on - classic cross-contamination through a shared party-wall stack. Our tech ran a Level 2 inspection with a camera and found the crown had a hairline crack running the full width of the shared masonry and the clay-tile flue liner had spalled near the top. We repaired the crown, installed a custom multi-flue cap sized to both flues, and showed the homeowner the camera footage before and after so she could see exactly what we fixed and why her neighbor’s side needed a look too. Shared stacks require shared awareness. Call (610) 991-8179 if you suspect cross-contamination.
We recommend crown coating only when camera and visual inspection confirm the underlying structure is sound - no separation from the brick, no deep cracking, no spalling. It’s a maintenance solution, not a rescue. For crowns that have cracked through, separated, or begun shedding pieces, we repair or rebuild. The difference is typically $280-$450 for coating versus $450-$1,200 for repair or rebuild. We show you the photos and explain which category yours falls into. No guesswork, no pressure. Call (610) 991-8179 for a free evaluation.
