Why Hearthstone Chimney Co. of Philadelphia Is Claymont’s Preferred Chimney Cap & Crown Company
We’ve been crossing the state line into Claymont since 1984. Over 42 years, we’ve capped and crowned chimneys in the Heights, along Governor Printz Boulevard, and throughout the old steelmill neighborhoods where the housing stock is remarkably consistent - and remarkably aged. Claymont homeowners tend to stay put. They know their house, they know its history, and they want a technician who recognizes that a 1952 Cape Cod chimney isn’t the same as a new construction flue.
Our Chimney Cap & Crown in Claymont reputation is built on showing up when we say we will, documenting what we find with camera photos you can see, and pricing the job upfront - the number on the estimate is the number on the invoice. No renegotiating on the ladder. Background-checked, uniformed technicians; most jobs done in one visit. And every repair is backed by our 90-Day Done Right Promise in writing - if it’s not right, we come back. No paperwork, no arguing.
Our Chimney Cap & Crown Services in Claymont
Crown Repair
Crown repair is where we start with most Claymont calls. The original concrete crowns on these 1940s-1960s chimneys were poured thin to begin with, and seventy years of Delaware River humidity and freeze-thaw cycles have taken their toll. We see spalling, cracking, and washout regularly - especially on homes within a few blocks of the river where the moisture load is heavier. Our crew removes the deteriorated material, forms a proper slope for water runoff, and pours a new crown with professional-grade compounds designed for this climate. Done right - and we stand behind it.
Custom Cap
Standard big-box caps don’t fit most Claymont chimneys. The flue dimensions on these older row homes and Cape Cods vary widely, and many have multiple flues or offset configurations from decades of heating-system changes. We measure on-site and fabricate custom caps from stainless steel or copper, sourced through Copperfield and Famco, to fit your exact chimney profile. A proper custom cap keeps rain, animals, and wind-driven debris out while allowing proper draft - critical on these older systems where the margin for error is already slim.
Cap Replacement
Missing or damaged caps are common in Claymont. Sometimes the original cap blew off in a nor’easter years ago and was never replaced. Sometimes a homeowner removed it and forgot. Either way, an uncapped flue is an open hole inviting water damage, squirrel nests, and accelerated crown deterioration. We stock replacement caps in common sizes and can install a properly fitted cap the same day we assess the crown. For Claymont’s original single-flue brick chimneys, this is often the simplest and most cost-effective protection you can add.
Crown Coating
When the crown damage is caught early - minor hairline cracking, slight surface erosion - a professional-grade crown coating can add years of life without full reconstruction. We use elastomeric compounds that flex with temperature swings and seal against the humidity that Claymont’s river location delivers in spades. Not every crown qualifies. We’ll tell you straight if coating is appropriate or if you’re throwing good money after bad. Photos you can see, a plain-English verdict.

Trusted Brands We Service in Claymont
We don’t use builder-grade substitutes. For Claymont chimneys, we specify materials from Olympia Chimney, Famco, and Copperfield - brands that hold up under real Mid-Atlantic conditions. Stainless steel caps from Famco resist the salt-laden air that drifts up from the Delaware River better than galvanized alternatives. Olympia Chimney’s flue components mate properly with the clay tile liners common to Claymont’s housing stock. We keep common sizes in stock, which means faster turnaround for Claymont homeowners and fewer return trips.
Common Chimney Cap & Crown Problems We See in Claymont Homes
- Cracked clay tile liners from freeze-thaw cycles. Claymont’s position on the river means more freeze-thaw stress than inland Newark or Wilmington. Water enters through a failed crown or missing cap, saturates the liner, and expands when it freezes. Horizontal cracks and separated mortar joints are what we find on camera inspection, almost every time.
- Improperly retrofitted coal chimneys with undersized flues. A high share of Claymont’s row homes burned coal originally, then switched to oil or gas without proper relining. The flue is too small or unlined entirely. Draft problems push smoke and carbon monoxide into living spaces. Cap and crown work alone won’t fix this, but a proper cap can reduce the water infiltration that makes liner damage worse - and we’ll flag the relining issue so you know exactly where you stand.
- Missing caps and animal entry. Squirrels, raccoons, and starlings love an open flue. We’ve pulled nests from Claymont chimneys that blocked the flue entirely. The cap that prevents this costs far less than the damage a trapped animal causes, or the carbon monoxide risk of a blocked flue.
- Spalling mortar and efflorescence on river-facing chimneys. The persistent humidity from the Delaware wicks into brickwork and dissolves salts, which then crystallize on the surface. This efflorescence is a warning sign. Left alone, it progresses to spalling - faces of brick popping off - and the crown crumbles with it. We see this pattern repeatedly on homes east of Philadelphia Pike.

FAQs - Chimney Cap & Crown in Claymont
Claymont’s liners are 60-80 years old, well past their designed service life, and subjected to heavier freeze-thaw stress than inland communities due to riverine humidity. The clay tiles become brittle, absorb moisture through crown or cap failures, and crack when water expands. Call (866) 580-4069 for a Level-2 camera inspection - estimates are free.
Most likely, yes. These chimneys were not built to modern standard dimensions, and many have multiple flues or odd configurations from heating-system changes. A stock cap won’t seal properly and can actually worsen draft problems. We measure and fabricate on-site. Call (866) 580-4069 to schedule a look.
The elevated humidity wicks into brick and mortar, accelerates efflorescence and spalling, and delivers more freeze-thaw cycles than communities just a few miles inland toward Newark or Wilmington. Crowns here deteriorate faster and need more vigilant inspection. Call (866) 580-4069 for a free assessment of your crown’s condition.
Visible rust, bent or missing mesh, gaps between cap and flue, water stains on interior walls near the chimney, or animal sounds in the flue. In Claymont, we also check for caps that were never replaced after blowing off in storms - common on older homes. Call (866) 580-4069 and we’ll confirm what you need.
We can repair the crown, but we will flag the relining issue in writing. Many Claymont chimneys converted from coal to oil or gas without proper relining, which is both a code violation under Delaware requirements and a carbon monoxide hazard. The crown repair protects against water infiltration, but it does not fix draft or safety issues from an unlined flue. We’ll show you photos and explain your options. Call (866) 580-4069 for a full inspection.
