Why Hearthstone Chimney Co. of Philadelphia Is Mercerville’s Preferred Chimney Liner & Rebuild Company
We’ve worked the postwar blocks of Hamilton Township long enough to know the failure patterns by heart. The 1950s ranches along Klockner Road, the Cape Cods off White Horse Pike, the split-levels near the Trenton line - we’ve rebuilt crowns, relined flues, and documented every job with photos the homeowner can see and a plain-English verdict. Our technicians are background-checked, uniformed, and carry professional-grade materials from DuraFlex, HeatShield, and Gelco so we’re not making a second trip for parts.
Mercerville customers call us back because we show up when we say we will, explain what we found without jargon, and put the 90-Day Done Right Promise in writing - no arguing, no paperwork chase. The number on the estimate is the number on the invoice. That’s the square deal.
Our Chimney Liner & Rebuild Services in Mercerville
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most Mercerville homes with cracked or oversized clay tile. In the 08619 corridor, where original liners were sized for coal combustion and now vent natural gas, a properly sized DuraFlex stainless liner restores draft and eliminates the chronic creosote buildup we see in these post-WWII ranches. We measure the appliance, calculate the correct diameter, and install it in one visit. Done right - and we stand behind it.

Flexible Liner Systems
Some Mercerville chimneys have offsets or bends that rigid pipe can’t navigate, especially in 1960s split-levels where the flue path was never straight to begin with. Flexible liners from trusted manufacturers thread through existing masonry without dismantling walls. We inspect with our Level-2 camera first, show you the footage, then recommend flex or rigid based on what your chimney actually needs.

Liner Replacement
When clay tiles are spalled, shifted, or missing entirely, patching is a temporary bandage. Liner replacement pulls out the failed material and installs a new, code-compliant system sized for your current heating appliance. In Mercerville’s mid-century housing stock, this is often the only way to stop carbon monoxide backdrafting and satisfy your homeowner’s insurance. We handle the full job: removal, sizing, installation, and final inspection documentation.

Partial Rebuild
Not every Mercerville chimney needs to come down to the roofline. If the upper courses are sound but the crown has cracked and water has infiltrated the top four or five feet, a partial rebuild restores structural integrity without the cost of full reconstruction. We match existing brick and mortar where possible, install a Gelco reinforced cap, and warranty the work under our 90-Day Done Right Promise.

Common Chimney Liner & Rebuild Problems We See in Mercerville Homes
- Shared flue arrangements. In 1950s Hamilton Township tract construction, one chimney often served both the furnace and the fireplace - a cost-cutting shortcut that violates current NJ code. When both appliances run, exhaust can backdraft into living spaces. We separate the flues or install a dedicated liner for each appliance.
- Oversized clay liners from coal-era construction. Original flues in Mercerville’s postwar ranches were built for coal or fuel-oil boilers. After natural-gas conversion, the flue is too large for the appliance, causing poor draft, cold spots, and accelerated creosote condensation. A properly sized stainless liner solves this permanently.
- Freeze-thaw spalling in mid-century masonry. The Delaware Valley’s hard winters drive moisture into cracked mortar joints, which expands when frozen and flakes off brick faces. We’ve rebuilt crowns and repointed chimneys on Klockner Road and throughout the 08619 ZIP where this cycle has destroyed original construction.
- Humid summer infiltration through failed crowns. Mercerville’s muggy off-seasons push moisture through cracked chimney caps and eroded crowns, soaking liner walls and accelerating deterioration before the first fall fire. A Gelco reinforced cap installation stops this at the source.

FAQs - Chimney Liner & Rebuild in Mercerville
The firebox is brick and mortar; the liner protects your house from heat and combustion gases. In Mercerville’s post-WWII ranches and Cape Cods, original clay tile liners were sized for coal or fuel-oil boilers, not modern natural-gas furnaces. After conversion, the flue is oversized, draft is poor, and carbon monoxide can spill into living spaces while the firebox still looks intact. Our Level-2 camera inspection shows you the actual liner condition - photos you can see, a plain-English verdict. Call (866) 580-4069 to schedule; estimates are free.
A partial rebuild is sufficient when damage is limited to the upper masonry, crown, and cap - which is common in 1960s Cape Cods where the original crown was never replaced and freeze-thaw cycling has spalled the top courses. If the crack extends below the roofline or the chimney is leaning, full rebuild is the only safe option. We document everything with photos and give you both options when they apply. For a free assessment of your specific chimney, call (866) 580-4069.
A DuraFlex stainless steel liner for a straight flue in a typical Mercerville ranch runs $2,800-$4,200 installed, including the cap and connector. If your chimney has offsets from a 1950s or 1960s construction shortcut, or if we need to separate a shared flue, the range moves to $3,500-$5,500. We measure on site, show you the camera footage, and give you one number that doesn’t change. Call (866) 580-4069 for an exact quote - estimates are free.
No - and you should not. Shared flues were common in 1950s Hamilton Township tract construction as a cost-saving measure, but they violate current NJ code and create dangerous backdrafting when both appliances operate. Exhaust from one appliance can enter the living space through the other appliance’s vent. Our Chimney Liner & Rebuild crew separates these systems with dedicated liners for each appliance. If you suspect a shared flue, call (866) 580-4069 for immediate inspection - this is not a wait-and-see situation.
We install DuraFlex stainless steel liners, HeatShield cerfractory resurfacing systems, and Gelco caps and crowns - all professional-grade materials, no builder-grade substitutes. We also stock Olympia Chimney and Famco components for specific applications. Our trucks carry common sizes, so most Mercerville jobs are completed in a single visit without waiting on parts. Call (866) 580-4069 to discuss which brand and system fits your chimney.
