We’ve worked Folsom’s neighborhoods for decades. The 19033 ZIP is our territory. We know the post-WWII Cape Cods along MacDade Boulevard, the brick twins clustered near Chester Pike, and the ranchers tucked behind Folsom Elementary. These houses share a common lineage: original chimneys built for coal, converted to oil, then gas, with clay flue liners now 60 to 80 years old and failing in predictable ways. That history matters when we’re sizing a new liner or deciding whether a chimney crown can be salvaged. Our Chimney Liner & Rebuild team treats every Folsom job with the patience the old masonry demands.

Our Chimney Liner & Rebuild Services in Folsom
Stainless Steel Liner Installation
Folsom’s oversized clay flues - originally engineered for coal furnaces - are the wrong size for modern gas appliances. A 6-inch stainless steel liner from DuraFlex drops the effective flue diameter to match your appliance’s BTU output, eliminating the condensation and draft failure that ruin oversized chimneys. We install these in Folsom Cape Cods and brick twins year-round, with most jobs finishing in four to six hours. The liner carries a lifetime warranty when we handle the installation.

Flexible Liner Systems
Some Folsom chimneys have offsets, corbels, or tight cleanout doors that make rigid liner insertion impossible. Flexible DuraFlex liners navigate these obstacles without dismantling the surrounding masonry. We’ve run flexible liners through Folsom’s narrow twin chimneys where a straight drop would have required a partial teardown. The material is the same professional-grade stainless; only the form changes to fit the house.

Liner Replacement
When a clay flue liner has shattered, spalled, or pulled away from the mortar joints, patching is not an option. We extract the failed liner - or work around it when extraction risks the surrounding brick - and install a new system sized precisely for your current heating appliance. In Folsom’s 1950s housing stock, this is the most common service we provide. The original liner was never meant to handle gas exhaust temperatures and corrosive condensate.

Partial Chimney Rebuild
Delaware County’s freeze-thaw cycle destroys chimney crowns and upper courses of brick faster than the stack below. A partial rebuild addresses the top three to six courses, the crown, and the flue termination without touching sound masonry lower down. On a cold February morning in a Folsom Cape Cod on Winslow Avenue, we found a 60-year-old clay flue liner shattered behind a gas-conversion water heater - oversized from the original coal furnace. We installed a 6-inch DuraFlex stainless steel liner and rebuilt the top three courses of brick. The homeowner’s next-door neighbor asked to have his twin unit inspected the same week. That’s Folsom in a nutshell.

Full Chimney Rebuild
When spalling brick, deteriorated mortar, and multiple flue failures compromise the structural integrity of the stack, we dismantle and rebuild from the roofline up - or from the foundation, if the damage extends that far. Full rebuilds in Folsom are less common than partial work, but we’ve completed them on century-old properties and on twins where deferred maintenance allowed water to destroy the wythe. Every rebuild uses matching brick and professional-grade materials from Copperfield and Gelco.

Trusted Brands We Service in Folsom
We don’t use builder-grade substitutes. Our Folsom installations rely on professional-grade materials from DuraFlex, HeatShield, Gelco, and Copperfield - brands that stand behind their products the way we stand behind our work. We stock common liner diameters and crown-forming materials locally, so most Folsom jobs don’t wait on parts. When a neighbor on your twin row needs matching work, we can often coordinate materials and scheduling to minimize disruption to both households. Done right - and we stand behind it.
Common Chimney Liner & Rebuild Problems We See in Folsom Homes
- Oversized flues producing corrosive condensate. Folsom’s original coal chimneys were built with 8-by-12 or larger clay flue tiles. Modern gas furnaces and water heaters run cooler and produce water vapor that condenses on those oversized surfaces, mixing with combustion byproducts to form sulfuric acid. The acid eats clay tile from the inside out. We see this in nearly every pre-1965 Folsom home we inspect.
- Freeze-thaw spalling on soft mortar joints. Delaware County’s winter temperatures cross 32°F repeatedly, day and night. Water infiltrates hairline cracks in mortar, expands when it freezes, and pops off brick faces or shatters flue tiles. Folsom’s chimneys suffer this more than newer suburbs to the west because the original mortar was lime-based and has weakened over 60 to 80 years.
- Shared party wall failures in brick twins. In Folsom’s post-WWII brick twins, a cracked liner on one side almost always signals an equally compromised flue on the neighbor’s side due to shared masonry party walls - so inspections routinely turn into two-job conversations. The thermal cycling and moisture migration don’t respect property lines.
- Deteriorated crowns allowing bulk water entry. The concrete or mortar cap at the top of a Folsom chimney was never meant to last 70 years. Once it cracks, water runs straight down the flue, accelerating liner damage and rusting metal dampers. A crown rebuild or a Gelco stainless steel chase cover stops this at the source.
Pricing for Chimney Liner & Rebuild in Folsom, PA
A typical stainless steel liner installation in a Folsom chimney runs $3,200-$5,800, depending on flue height, diameter, and whether the chimney needs a new crown or top-sealing damper. Partial rebuilds of the upper brick and crown typically fall between $4,500 and $8,000. Full chimney rebuilds in Folsom start around $12,000 and can exceed $18,000 for tall stacks with multiple flues or matching historic brick.
What moves the number: accessibility (steep roof pitches cost more in labor), the condition of existing masonry, whether we coordinate with a neighbor on a twin, and the appliance type we’re lining for. We provide no-hassle upfront pricing after our Level-2 inspection. The estimate is free. The number on the estimate is the number on the invoice.

FAQs - Chimney Liner & Rebuild in Folsom
Yes, but only with a properly sized stainless steel liner installed. The original clay flue is almost certainly oversized for your gas furnace and will produce dangerous condensation and carbon monoxide spillage without modification. We’ve relined dozens of Folsom Cape Cods from the 1945-1965 era. Call (866) 580-4069 to schedule a Level-2 inspection - estimates are free.
Yes. In Folsom’s brick twins, the shared masonry party wall means liner damage on one side predicts identical hidden damage on your side. Our technicians routinely find matching flue deterioration when we inspect the adjoining unit. The inspection includes photos you can see and a plain-English verdict. Call (866) 580-4069 - we’ll coordinate with your neighbor if both units need work.
Most stainless steel liner installations in Folsom run between $3,200 and $5,800, with the final price depending on flue height, diameter, and whether your chimney needs crown or damper work at the same time. We provide upfront pricing after inspection, with no surprises on the bill. Call (866) 580-4069 for a free estimate on your specific chimney.
Yes. Partial rebuilds address failed crowns, spalled upper brick, and deteriorated flue terminations while preserving sound masonry below. Most Folsom partial rebuilds involve the top three to six courses and cost $4,500-$8,000. We’ll document the condition with camera inspection photos and recommend only the work your chimney actually needs. Call (866) 580-4069 to schedule.
It often is. A cracked or missing flue liner allows combustion gases to leak through gaps in the clay tile into surrounding masonry or living spaces, producing smoke odors or elevated carbon monoxide risk. In Folsom’s aging chimneys, we’ve traced smoke smells to shattered liners behind gas inserts and to deteriorated mortar joints in the smoke chamber. This warrants immediate inspection. Call (866) 580-4069 - a live person answers 24/7.
