We’ve been working on Drexel Hill chimneys since 1984. The housing stock here is unlike anywhere else in Delaware County. Row after row of 1920s-to-1950s brick twins line streets like Burmont Road, Marshall Road, and State Road, and nearly all of them share a single chimney chase straddling the property line. That shared masonry was built for coal boilers, converted to oil, then converted again to gas - and the oversized flues, aged mortar, and freeze-thaw damage create repair situations our crews see nowhere else. Our Chimney Repair team knows Upper Darby Township’s code expectations and how to handle the neighbor-notification conversation that comes with almost every twin-home job.
Why Hearthstone Chimney Co. of Philadelphia Is Drexel Hill’s Preferred Chimney Repair Company
Forty-two years in this region means we’ve watched Drexel Hill’s chimneys age through multiple fuel conversions and countless freeze-thaw cycles. Carl Bridwell founded this company in 1984 on a simple standard: document what you find, explain it plainly, and stand behind the repair. That standard still governs every job we run in Drexel Hill.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict - no jargon, no scare tactics. If we find a cracked flue tile in your half of a shared twin chimney, we’ll show you exactly where the break is, explain why Upper Darby Township will require both units to meet code, and walk you through the repair options. Most Drexel Hill repairs are completed in one visit by background-checked, uniformed technicians who arrive with professional-grade materials from brands like DuraFlex, HeatShield, and Gelco already on the truck.
Our 90-Day Done Right Promise applies to every Drexel Hill job in writing, with no arguing. If something isn’t right, we come back. We’ve been answering the phone with a live person for over four decades, and we plan to be here for decades more - that’s why we treat every shared-chimney conversation with the care it deserves. A botched repair on a property-line chase can sour a neighbor relationship for years.
We recently repaired a spalling brick interior on a shared chimney at a twin home on Burmont Road, where the original coal flue had been relined with a DuraFlex stainless steel liner after the homeowner’s oil-to-gas conversion - our crew worked both halves of the chase to stop water infiltration that was damaging adjacent units. Jobs like this are routine for us. They’re puzzles for less experienced operators.
Our Chimney Repair Services in Drexel Hill
Mortar Repointing
Drexel Hill’s freeze-thaw cycles are brutal on 80-to-100-year-old mortar. January temperatures swing repeatedly above and below freezing, and that expansion-contraction pattern opens hairline cracks in joints that water then penetrates and widens. On a twin home, deteriorated mortar on the exterior chase doesn’t just threaten your unit - it compromises the shared masonry your neighbor depends on too. Our repointing matches original mortar composition and compressive strength, and we grind out failed joints to proper depth rather than smearing surface patches that fail in two seasons. A typical repointing job on a Drexel Hill twin chimney runs $850-$1,800 depending on accessibility and how many courses need attention.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is everywhere on Drexel Hill’s older chimneys. It’s caused by moisture freezing inside the brick matrix, and it’s especially aggressive on stacks that lack proper crowns or flashing. We cut out spalled brick to sound substrate, install matching replacements, and address the water source so it doesn’t recur. On shared chimneys, spalling on one side often indicates systemic moisture intrusion affecting the entire chase. Our inspection will document conditions on both halves so you and your neighbor have the full picture before Upper Darby Township gets involved. Spalling repair on a Drexel Hill chimney typically ranges from $1,200 to $2,800.
Chimney Waterproofing
After repointing or spalling repair, waterproofing is not optional in Drexel Hill - it’s preventive maintenance that pays for itself. We apply vapor-permeable sealants formulated for historic masonry, not the film-forming products that trap moisture and accelerate damage. Waterproofing a Drexel Hill twin chimney runs $450-$950 and includes crown sealing, cap inspection, and flashing evaluation. Given that a single wet winter can destroy newly repointed joints, this is money spent once to avoid spending it again.
Flashing Repair
Step flashing and counterflashing on Drexel Hill’s older homes often consists of original galvanized steel that’s rusted through or was never properly integrated with the roof membrane. We fabricate custom flashing from professional-grade materials and integrate it correctly with your roofing system. Poor flashing is the leading cause of interior water damage on twin-home chimneys in this area, and the leaks rarely respect the property line - we’ve seen ceiling stains appear on the “good” side while the source was flashing failure on the other. Flashing repair typically runs $650-$1,400 in Drexel Hill.
Chimney Rebuilding
When deterioration exceeds 30 percent of the stack, partial or full rebuilding becomes the only sound option. This is more common on Drexel Hill chimneys than many homeowners expect, given the age of the housing stock and the cumulative damage from coal soot, oil residue, and decades of freeze-thaw. We rebuild with matching brick and proper structural ties, and on shared chases we coordinate with both property owners to ensure the rebuilt stack meets current Upper Darby Township code for both flues. Full rebuilding of a Drexel Hill twin chimney typically ranges from $3,200 to $4,500.
Tuckpointing
For chimneys where the mortar is sound but the aesthetic finish has weathered, tuckpointing restores the clean, narrow joint lines that were original to 1920s and 1930s construction. It’s less invasive than full repointing and can extend the life of sound mortar by improving water shedding. Tuckpointing on a Drexel Hill chimney runs $600-$1,100.

Trusted Brands We Service in Drexel Hill
We stock DuraFlex stainless steel liners, HeatShield cerfractory flue sealant, and Gelco chimney caps on our Drexel Hill-area trucks, which means most repairs don’t wait for parts orders. DuraFlex liners are especially critical for the oil-to-gas conversions common in Drexel Hill’s twin homes - the flexible design accommodates the offset flues and tight clearances that rigid liners can’t navigate in these older structures. HeatShield handles the resurfacing of eroded clay flue tiles without full relining, a cost-effective solution when the tile body is sound but the surface has degraded from years of oil soot. We don’t substitute builder-grade materials. The brands we use are the same ones specified by chimney engineers for commercial installations. They cost more upfront. They cost less over the life of the repair.
Common Chimney Repair Problems We See in Drexel Hill Homes
- Oversized coal-era flues causing backdraft in gas appliances. The original flues in Drexel Hill’s twin homes were sized for coal boilers with massive draft requirements. Modern gas furnaces and water heaters can’t generate enough flow to prevent spillage in those large bores. We measure flue dimensions against appliance BTU output and install properly sized DuraFlex liners when there’s a mismatch.
- Freeze-thaw destruction of soft historic mortar. Drexel Hill sits squarely in the Mid-Atlantic freeze-thaw belt, with January temperatures cycling repeatedly above and below freezing - a pattern that aggressively attacks the soft mortar joints and chimney crowns on 80-to-100-year-old masonry stacks. Annual chimney inspections are especially critical here because a single winter can open hairline cracks that allow water infiltration into the shared interior masonry that both halves of a twin depend on.
- Hidden flue damage in shared chimney chases. On a twin home, the chimney chase is co-owned masonry sitting on the property line - when a technician finds a cracked flue tile or spalling brick interior on one unit, the damage almost always affects the adjoining neighbor’s flue as well, and Upper Darby Township’s code enforcement expects both units to be brought into compliance together, a conversation local techs have to be prepared to initiate at almost every twin-home job.
- Failed chimney crowns and deteriorated flashing on roofs with multiple layers. Many Drexel Hill homes have had two or three roof overlays without proper flashing replacement. The accumulated weight and compromised sealants funnel water directly into the chimney structure, accelerating all other forms of deterioration.

FAQs - Chimney Repair in Drexel Hill
Upper Darby Township code enforcement treats a shared chimney chase as a single structural entity, so a defect in one flue typically renders the entire assembly non-compliant. When we find a cracked flue tile or spalling brick interior on one side, the damage pattern almost always compromises the adjoining neighbor’s flue as well - the masonry is literally the same wall. Bringing only one unit to code leaves the shared structure partially hazardous, which the township won’t approve. We document conditions on both sides during our Level-2 inspection and can present findings to both homeowners. Call (866) 580-4069 to schedule - estimates are free, and we’ll handle the neighbor conversation with the same plain-English clarity we bring to every job.
The most reliable indicator is a draft test performed during a Level-2 inspection, but warning signs include condensation staining on the flue walls, a persistent sulfur or gas odor near the appliance, and frequent pilot light failures. Drexel Hill’s original coal flues typically measure 8×12 inches or larger - modern gas furnaces need 5- to 6-inch round liners to generate proper draft velocity. An oversized flue allows combustion gases to cool and stall before reaching the top, which can cause carbon monoxide spillage into living spaces. We measure flue dimensions and appliance output on every inspection and specify DuraFlex liner sizing when there’s a mismatch. Call (866) 580-4069 for a draft evaluation - the $89 Seasonal Tune-Up includes basic draft assessment.
Mortar repointing is the most frequent repair we perform on Drexel Hill’s brick twins, driven by the combination of 80-to-100-year-old soft lime mortar and aggressive Mid-Atlantic freeze-thaw cycling. The mortar joints on these chimneys were never designed to withstand decades of thermal shock, and once joints begin receding, water penetration accelerates deterioration of the entire shared structure. We typically repoint one or both sides of a twin chimney on Burmont Road, Marshall Road, or State Road at least weekly during repair season. Call (866) 580-4069 for an inspection - catching joint failure early prevents the $3,000-plus cost of full rebuilding.
Sometimes, if the crack is strictly confined to your flue liner and the surrounding masonry is sound - but on Drexel Hill twins, cracks are rarely that isolated. The shared construction means thermal stress and moisture migration affect both flues, and Upper Darby Township’s inspectors are trained to examine the entire chase. We use our camera system to map damage extent before recommending any repair path, and we’ll show you exactly what we see so you can make an informed decision with your neighbor. Call (866) 580-4069 to schedule a documented inspection - photos you can see, a plain-English verdict.
Yes - waterproofing is essential follow-up to repointing in Drexel Hill’s climate. Fresh mortar needs 28 days to fully cure, and during that window it’s especially vulnerable to water penetration from rain and melting snow. Our freeze-thaw belt delivers multiple wet-freeze cycles every winter that can destroy newly placed joints before they harden. We apply vapor-permeable sealant formulated for historic masonry that allows the wall to breathe while shedding liquid water. The combination of proper repointing and professional waterproofing typically extends chimney life by 20-plus years on Drexel Hill homes. Call (866) 580-4069 to add waterproofing to your repair scope - we’ll bundle it for a square deal.
