Fast, Reliable Chimney Liner & Rebuild Across Philadelphia
A stainless steel chimney liner installed in a Philadelphia row house typically runs $2,800-$4,500, while a full chimney rebuild on a shared party-wall stack can reach $8,000-$15,000 depending on height and access. Most liner replacements and partial rebuilds we handle in Philadelphia are completed in a single day, with our crew arriving from our regional base to reach Center City, South Philadelphia, and the river wards within standard scheduling windows.
We’ve been working on Philadelphia chimneys long enough to know the difference between a 1910 Point Breeze row house and a 1920s Fishtown twin. The brick is different. The mortar is different. And the way three flues are packed into one party-wall stack, each serving a different appliance in a different unit, is nothing like the detached chimneys you’ll find out in Montgomery County. When we say we understand Philadelphia chimneys, we mean we’ve spent decades tracing flues through walls that were built before the Great Depression, documenting what we find with photos you can see and a plain-English verdict you can act on. If your chimney liner is failing or your stack needs rebuilding, call (844) 803-1545. A live person answers, 24 hours a day, and we’ll schedule a Level-2 camera inspection that shows you exactly what’s happening inside your flue.
Why Hearthstone Chimney Co. Is Philadelphia’s Preferred Chimney Liner & Rebuild Company
Philadelphia homeowners don’t need a sales pitch. They need a crew that shows up when promised, does the work correctly, and stands behind it without a fight. That’s been our approach for over 42 years.
Our reputation here was built one row house at a time. We’ve replaced liners in Queen Village where the original clay flue had crumbled to powder after 130 years of service. We’ve rebuilt crowns in Old City where freeze-thaw cycles had turned mortar joints to sand. In each case, we documented the condition with camera footage, explained the repair in plain terms, and delivered a written estimate with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
Response time matters in a city where a failed liner in January means no heat. We schedule Philadelphia appointments with urgency appropriate to the season and the condition. Our technicians are background-checked, uniformed, and carry the professional-grade materials to complete most jobs in a single visit. And if something isn’t right, our 90-Day Done Right Promise means we come back and make it right, in writing, no arguing. That’s the Keystone Standard we’ve operated by since 1984.
Our Chimney Liner & Rebuild Services in Philadelphia
Stainless Steel Liner Installation
For most Philadelphia row houses with gas furnaces, water heaters, or wood-burning inserts, a stainless steel liner is the correct long-term solution. We size the liner to the appliance, not the oversized coal-era flue, using DuraFlex and Olympia Chimney products rated for the specific fuel type. In South Philadelphia and Kensington, where we’ve encountered countless unlined flues still serving 1950s-converted gas appliances, this proper sizing eliminates the chronic backdrafting and CO risk that oversized flues create. A typical stainless steel liner installation in Philadelphia runs $2,800-$4,500 for a standard single-flue application.
Flexible Liner Installation
Some Philadelphia chimneys have offsets or bends that rigid stainless cannot navigate, particularly in older homes where the flue path was never straight to begin with. Flexible liners from trusted manufacturers allow us to thread a proper venting path through compromised masonry without dismantling the stack. We’ve installed flexible liners in West Philadelphia homes where the original builder used every shortcut imaginable, and where a rigid liner would have required destructive wall access. Flexible liner installations in Philadelphia typically range from $3,200-$5,000 depending on length and complexity.
Liner Replacement
When an existing liner has failed, corroded, or been improperly sized from a previous installation, full replacement is often the only safe option. In Philadelphia’s humid summers and freeze-thaw winters, we’ve pulled out liners that lasted barely a decade because they were the wrong alloy for the fuel type or because moisture trapped behind a deteriorating crown accelerated corrosion. Our liner replacement process includes a full camera inspection of the remaining masonry, repair of any accessible damage, and installation of a correctly specified replacement. Liner replacement in Philadelphia generally costs $2,500-$4,800.
Partial Chimney Rebuild
Not every failing stack needs to come down to the roofline. In Philadelphia, where party-wall chimneys often show concentrated damage at the crown, shoulder, or above-roof portion while the lower masonry remains sound, a partial rebuild preserves what works and fixes what doesn’t. We’ve rebuilt the upper sections of chimneys in Graduate Hospital and Fairmount where spalling brick and missing mortar had opened gaps for water and flue gases, while the flues below remained structurally adequate. Partial rebuilds in Philadelphia typically run $3,500-$7,500 depending on height and the extent of brick replacement required.

Trusted Brands We Service in Philadelphia
We don’t use builder-grade substitutes, and we don’t substitute on the fly without telling you. Our trucks carry professional-grade materials from HeatShield, Gelco, and Famco, among others, so when our technician arrives at your Philadelphia home, the correct liner, cap, or crown material is already on hand. That inventory discipline is why we complete most jobs in a single visit. HeatShield’s cerfractory coating system, for instance, allows us to resurface deteriorating clay flues in certain Philadelphia applications where full relining isn’t necessary, saving the homeowner significant cost while restoring a safe, smooth venting surface. Gelco caps and Famco components handle the harsh Philadelphia freeze-thaw cycle without the premature failure we’ve seen from generic hardware-store equivalents.
Common Chimney Liner & Rebuild Problems We See in Philadelphia Homes
- Original coal-era flues never relined for gas conversion. In row houses throughout South Philadelphia and Center City, we regularly find that the 1950s-70s conversion from coal to gas left an oversize, unlined flue serving a modern appliance. The flue is too large to maintain proper draft, creating backdrafting conditions that vent carbon monoxide into living spaces. Only a Level-2 camera inspection reveals this pattern.
- Freeze-thaw destruction of soft, high-lime mortar. Philadelphia’s mid-Atlantic winter delivers repeated freeze-thaw cycling from November through March. The pre-1900 mortar in our oldest row houses absorbs moisture, expands when frozen, and spalls off in layers. By March, we’ve fielded dozens of calls from homeowners who watched chunks of brick fall from their chimney during the last cold snap.
- Multi-flue party-wall confusion. The shared chimney stack serving adjacent row house units contains multiple flues, and previous work often misidentified which flue served which appliance. We’ve found gas water heaters venting into flues still connected to a neighbor’s fireplace, and fireplace flues capped while the furnace below continues to exhaust into the wall cavity. Correct identification is life-safety work.
- Creosote stratification in seasonally used flues. Philadelphia’s humid summers allow creosote deposits in wood-burning flues to absorb moisture and stratify into harder, more acidic layers. When the homeowner lights the first fire in October, that degraded creosote accelerates liner corrosion and can contribute to chimney fires in unlined or poorly lined systems.

Philadelphia row house work is often more labor-intensive than detached-home jobs in suburbs like Lower Merion or Cherry Hill due to party-wall access constraints, tighter working conditions, and the complexity of multi-flue identification. However, our pricing reflects actual scope, not ZIP code. A straightforward liner replacement in a Philadelphia row house may cost less than a full rebuild on a large suburban home. We provide the same no-hassle upfront pricing everywhere we work. Call (844) 803-1545 for your specific estimate.
All our work is covered by the 90-Day Done Right Promise, in writing, with no arguing. If it’s not right, we come back and make it right.

We document every warranty and registration so you have it in hand. For warranty details on your specific job, call (844) 803-1545.

That’s how we’ve worked for over 42 years. Call (844) 803-1545 now. A live person will answer, and your estimate is free.
