Why Hearthstone Chimney Co. of Philadelphia Is Collingdale’s Preferred Chimney Repair Company
We’ve worked on Collingdale chimneys for over 42 years. That means we’ve seen the same patterns repeat: coal-era clay liners cracked after gas conversions, mortar joints ground down by freeze-thaw cycles, twin-home flues that weren’t properly separated when the neighborhood was built. Our customers in Collingdale don’t call us for flashy marketing. They call because their neighbor on Ashland Avenue recommended us, or because we fixed their sister’s chimney on Clifton Avenue last winter and the job still looks solid.
Our response time to Collingdale averages under an hour. We’re based in Philadelphia, but Delaware County is our daily route - MacDade Boulevard to Springfield Road, we know the traffic patterns and the parking situations on Collingdale’s narrow streets. Every technician is background-checked and uniformed. Most repairs finish in one visit. Our 90-Day Done Right Promise covers every job in writing: if it’s not right, we come back. No paperwork, no arguing.
Carl Bridwell, our owner, still reviews photos from every Level-2 camera inspection that goes out with a Collingdale address. The verdict comes in plain English, not contractor jargon. You see what we see.
Our Chimney Repair Services in Collingdale
Mortar Repointing
Collingdale’s century-old brick chimneys were laid with lime mortar that has now turned to powder in too many places. The freeze-thaw cycle here - temperatures crossing 32°F dozens of times each winter - forces water into those joints, expands it, and pops the face off your brick. Mortar repointing in Collingdale runs $18-$28 per square foot of joint, and a typical twin-home chimney needs 30-60 square feet. We grind out the bad material to proper depth and repack with HeatShield-compatible refractory mortar, color-matched to your existing brick. Done right, it buys you 25-30 years.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic on Collingdale’s exposed end-wall chimneys. These stacks take the full brunt of wind-driven rain off Darby Creek and then freeze overnight. Once the face pops off, the inner brick soaks up more water, and the cycle accelerates. We cut out spalled units and replace with matching reclaimed or new brick, then seal with a vapor-permeable treatment. Partial spalling repairs start around $650; a full face rebuild on a twin-home stack can reach $2,400. We always check whether the root cause is a failed crown or missing cap before we quote brick work alone.
Chimney Waterproofing
Collingdale’s humid summers drive moisture into chimney masonry that winter freeze-thaw then exploits. We apply professional-grade water repellents from Copperfield - silane/siloxane formulations that let vapor escape while blocking liquid water. A typical twin-home chimney in Collingdale runs $380-$550 for full treatment, including minor crack prep. We won’t waterproof over active leaks; if your crown is cracked or your flashing is lifted, we fix that first. Waterproofing a damaged chimney just traps water inside.
Flashing Repair
The intersection where your chimney passes through the roof is the single most leak-prone point on any Collingdale home. On twin homes, this gets worse - shared wall flashings often were installed as one continuous piece in the 1920s, and decades of differential settling between units have pulled the seams apart. We remove old flashing, inspect the deck and framing for rot (common on Collingdale’s older roofs), and install new step and counter flashing with proper kickout diverters. Flashing repair in Collingdale typically costs $450-$950. If the chimney itself has shifted, we may recommend stabilization before re-flashing.
Chimney Rebuilding
Some Collingdale chimneys are too far gone for spot repair. When the stack leans, when multiple courses have lost structural integrity, when a Level-2 inspection reveals liner damage combined with exterior failure, we quote rebuilds. A partial rebuild from the roofline up on a twin-home chimney runs $2,200-$3,800; a full teardown and rebuild can reach $6,500-$9,000 depending on height and access. We reuse sound original brick where possible, match new to old, and always install a proper liner system before we close up. Carl Bridwell personally signs off on every rebuild scope.
Tuckpointing
For Collingdale homeowners who want to preserve the original appearance of their 1920s brickwork, tuckpointing replaces weathered mortar with precisely tooled joints that replicate the fine lines of historic construction. It’s slower work than standard repointing, and it costs more - $32-$45 per square foot - but on a front-facing twin-home chimney in Collingdale, the visual difference matters. We match sand content and tooling style to your existing joints.

Trusted Brands We Service in Collingdale
We don’t use builder-grade substitutes. For liner installations in Collingdale’s converted coal chimneys, we specify DuraFlex stainless steel or HeatShield cerfractory flue sealant, depending on the flue condition and appliance type. For caps, dampers, and repair components, we stock Famco and Copperfield hardware - parts we can source fast, so your Collingdale job doesn’t wait on shipping. Our trucks carry the common sizes for twin-home flue dimensions, which means most repairs start and finish the same day.
Common Chimney Repair Problems We See in Collingdale Homes
- Cracked or missing clay tile liners from coal-era chimneys. When Collingdale’s original coal furnaces were swapped for gas or oil, the flues were often left unlined or with deteriorating clay. Flue gases now leak through those cracks into interior walls. Every inspection we perform in 19023 includes a full liner evaluation - it’s not optional here.
- Oversized flues causing condensation damage. A coal flue might measure 8×12 inches; your modern high-efficiency gas furnace needs a 4-inch liner. Without proper sizing, exhaust cools too fast, condenses into acidic water, and eats mortar from the inside out. We see this on MacDade Boulevard twins constantly.
- Freeze-thaw spalling on exposed end walls. The twin homes on Clifton Avenue and Woodland Terrace with end-wall chimneys take the worst of it. Brick faces pop off in sheets after hard winters. Caught early, it’s a repointing job. Ignored for three years, it becomes a rebuild.
- Shared-flue cross-contamination in twin homes. One exterior stack, two flues, one technician who doesn’t check before rodding. We’ve cleaned debris out of neighbors’ flues that another crew deposited. Our mirror-and-drop-light verification takes 90 seconds. It happens every time.

FAQs - Chimney Repair in Collingdale
Your chimney was built in the 1920s or 1930s to serve two separate units under one roof, with one flue for each side. The exterior stack is shared, but the flues should be divided by a wythe of brick or a tile partition. Over decades, that partition can crack or deteriorate, allowing smoke and gases to cross between units. We verify flue separation with a mirror and drop light before any work begins. Call (866) 580-4069 if you suspect cross-drafting - we’ll check it with a Level-2 inspection.
Almost certainly, yes. Collingdale’s coal-era chimneys were built for 500°F+ flue gases and strong draft. Modern gas furnaces produce cooler, wetter exhaust that an unlined masonry flue cannot handle. The acidic condensation eats mortar from the inside, and the oversized flue never develops proper draft. On a recent job on Franklin Street, we repaired a 1920s brick twin’s flue where a homeowner’s DIY gas conversion left the coal-era clay liner cracked. We installed a DuraFlex stainless steel liner to properly vent their new furnace, ending years of backdrafting and carbon monoxide worries. A liner inspection costs nothing extra during our standard service call.
The Philadelphia-area freeze-thaw cycle - with temperatures repeatedly crossing 32°F throughout winter - is especially punishing on Collingdale’s century-old brick chimney stacks, accelerating spalling and mortar joint failure. Humid mid-Atlantic summers then allow moisture into those gaps, compounding interior liner damage between annual cleaning visits. We schedule more repointing and crown repair calls in Collingdale in March and April than in any other two-month period. The key is catching it before freeze-thaw turns a $600 repointing into a $3,000 rebuild. Call (866) 580-4069 for a pre-winter inspection.
Yes, if the chimney structure itself is sound and hasn’t shifted. We remove the old step and counter flashing, inspect the roof deck for rot (common on Collingdale’s older homes), and install new galvanized or copper flashing with proper kickout diverters. If the chimney has settled or tilted away from the building, flashing alone won’t seal it - we need to stabilize first. A standalone flashing repair in Collingdale runs $450-$950. We’ll tell you straight which situation you’re in after we inspect.
Repair when the damage is localized - spalling on the top few courses, mortar erosion in the upper joints, a cracked crown, or isolated flashing failure. Replace when you see structural movement (leaning, separation from the house), widespread brick loss through multiple courses, or liner damage combined with exterior deterioration that makes relining impractical. In Collingdale’s twin homes, we also factor in whether both units’ flues can be properly separated and lined. Sometimes a full rebuild with new flue construction is the only way to make both sides safe. We’ll show you the camera footage and give you both numbers - repair and replace - so you decide. Estimates are free: (866) 580-4069.
