Why Hearthstone Chimney Co. of Philadelphia Is Swarthmore’s Preferred Chimney Cap & Crown Company
We’ve been providing Swarthmore Chimney Cleaning & Sweep services for over 42 years, since the company started in 1984.

Our Chimney Cap & Crown Services in Swarthmore
Multi-Flue Cap Installation
Most Swarthmore homes built between 1880 and 1930 have multi-flue chimneys, often with one flue for a converted coal furnace and another for our Fireplace Services in Swarthmore to address. A single-flue cap leaves the other flue exposed, or worse, two mismatched caps create gaps where water and animals enter. We measure each flue precisely and install a heavy-duty multi-flue cap, often from Copperfield, that covers the entire chimney top with proper overhang and screen height. This is the solution we recommend for most Yale Avenue and Dartmouth Avenue Victorians.
Crown Repair
The crown is the concrete or mortar slab that seals the chimney top between the flue tiles and the brick edge. In Swarthmore, original coal-era crowns rarely have proper overhang or slope, so rainwater runs straight down the chimney face, eroding brick and mortar joints. We rebuild crowns with proper drainage geometry, or when the damage is moderate, we apply a HeatShield crown coating that seals cracks and restores slope without full replacement. Either way, the goal is the same: water goes to the gutter, not into your flue.
Custom Cap Fabrication
Some Swarthmore chimneys, especially on the larger Queen Anne and Arts-and-Crafts homes near the SEPTA station, have unusual flue configurations, decorative chimney pots, or offset flues that no standard cap fits. We template these on-site and fabricate custom caps from stainless steel or copper that match the chimney’s dimensions exactly. A proper custom cap on a 130-year-old chimney isn’t an upgrade, it’s protection against the kind of water damage that costs ten times more to repair later.
Crown Coating
For crowns with surface cracking but solid structural integrity, we apply a professional-grade crown coating, typically HeatShield, that bridges hairline cracks and creates a waterproof, slightly flexible surface. This works well on Swarthmore chimneys where the crown is basically sound but the freeze-thaw cycle has started spider-webbing the surface. It’s less expensive than a full rebuild, and when applied correctly, it extends the crown’s life by years. We only recommend coating when the crown beneath is worth saving; if the concrete is spalling or the reinforcement is exposed, we tell you straight and price a rebuild instead.

Trusted Brands We Service in Swarthmore
We stock caps, crowns, and repair materials from professional-grade brands: Copperfield for heavy-duty stainless and copper caps, HeatShield for crown coatings and liner restoration, and Gelco for multi-flue and custom applications. These aren’t builder-grade substitutes from a hardware store; they’re the products we trust on chimneys that need to last another century. Because we carry inventory for Swarthmore’s older housing stock, we rarely need to order parts and wait. Most Swarthmore homeowners get their cap or crown problem diagnosed and fixed in the same appointment.
Common Chimney Cap & Crown Problems We See in Swarthmore Homes
- Leaf litter and nesting material block caps faster here than anywhere nearby. Swarthmore’s Tree City USA canopy of mature oaks, maples, and sycamores overhangs nearly every roofline. Technicians regularly pull out caps packed with acorns, maple leaves, and chimney swift nesting material that would be unusual in the more open streetscapes of Ridley Township or Morton. A blocked cap traps moisture, and that moisture accelerates crown spalling through freeze-thaw damage.
- Soft, century-old mortar joints erode from acidic oak leaf tannins. When leaves sit against mortar joints under a loose or missing cap, the tannins leach into the mortar and break down the bond. We’ve seen 120-year-old mortar turn to sand beneath caps that looked fine from the ground. The fix isn’t just a new cap; it’s re-pointing the top course and sealing the crown so leaves can’t collect in the first place.
- Original coal-era crowns lack proper overhang and slope. These crowns were poured flat or slightly dished, sometimes with no overhang at all. Rainwater runs down the chimney face, eroding brick and washing out mortar joints. By the time homeowners notice water stains inside, the damage has worked halfway down the chimney. We rebuild with minimum 2-inch overhang and proper slope to the edge.
- Freeze-thaw cycles from November through March destroy clay liner tiles and crown concrete. The Delaware Valley’s pattern of warm days and hard freezes lets water penetrate micro-cracks, expand, and widen them. On Swarthmore’s 19th-century chimneys with softer original mortar, this happens faster than in newer construction. Annual inspection catches it before a single winter turns small cracks into structural failure.
Pricing for Chimney Cap & Crown in Swarthmore, PA
Here’s what cap and crown work costs in the Swarthmore market. These are real ranges based on jobs we’ve completed in the 19081 zip code:
- Standard single-flue cap replacement: $280-$420
- Multi-flue cap installation: $450-$720
- Custom cap (stainless or copper): $680-$1,200
- Crown coating with crack repair: $340-$550
- Partial crown rebuild: $580-$890
- Full crown removal and rebuild: $920-$1,600
What moves the price? Height and access matter. A three-story Victorian on Yale Avenue with a steep roof costs more than a two-story bungalow with easy ladder placement. The condition of the existing crown determines whether we coat, patch, or rebuild. And custom caps require on-site templating and fabrication time.

FAQs - Chimney Cap & Crown in Swarthmore
Because Swarthmore’s mature oak, maple, and sycamore canopy drops more leaf litter per square foot than almost anywhere in Delaware County. The borough’s Tree City USA designation means heavy overhang on nearly every street, and standard mesh screens clog fast. We install caps with larger screen area or raised hood designs that shed debris better. Call (866) 580-4069 and we’ll recommend the right cap for your tree cover.
Probably. Most Dartmouth Avenue Victorians have multi-flue chimneys with offset flues, decorative brickwork, or flue tiles that don’t align with standard cap sizes. We template on-site and fabricate a cap that fits exactly, usually in stainless steel or copper. A stock cap forced onto an irregular chimney leaves gaps that let in water and animals. We’ll measure and quote while we’re there.
Yes, if the crown is structurally sound and the cracks are surface-level. We clean the crown, fill cracks, and apply a HeatShield coating that seals and waterproofs. This runs $340-$550 in Swarthmore, compared to $920-$1,600 for full rebuild. If the concrete is spalling or reinforcement is visible, we’ll tell you coating won’t last and price a rebuild instead. No upsell, just the honest call.
Three reasons specific to this borough: the heavy tree canopy accelerates cap clogging and mortar erosion from leaf tannins; the 90-130 year old housing stock has original crowns without proper overhang or slope; and the Delaware Valley freeze-thaw cycle attacks the softer mortar and clay tile in these coal-era chimneys harder than it does modern construction. Maintenance intervals here should be shorter, not longer.
The nest is likely blocking the flue, not the cap itself. Chimney swifts and squirrels are common in Swarthmore, and nesting material can completely obstruct a flue or knock clay liner tiles out of alignment. We remove the nest, inspect with a Level-2 camera so you can see the flue condition, and reinstall or replace the cap with proper screen height to prevent re-entry. Call (866) 580-4069; blocked flues are a carbon monoxide risk and we prioritize them.
On a Victorian on Yale Avenue, we found the crown cracked and a cap packed with maple leaves and swift droppings; we installed a heavy-duty copper multi-flue cap from Copperfield and sealed the crown with HeatShield coating, ending a seasonal water leak that had rotted the damper frame.
Swarthmore’s housing stock demands a different approach than standard suburban chimneys. The coal-to-modern conversion legacy means mismatched flue sizing, deteriorated clay tile liners, and century-old mortar joints are the defining problems here. Generic cap and crown advice from a national chain won’t address the specific failure modes we see on Yale Avenue, Dartmouth Avenue, and throughout the 19081 zip code, which is why our Chimney Repair in Swarthmore is tailored to these exact conditions. We know these chimneys because we’ve worked on them for over 42 years.
