Call (866) 580-4069 - a live person answers, even at 10 PM on a Sunday.
Green Tree Borough sits in the South Hills of Allegheny County, where the steep valley terrain and post-WWII ranch and split-level housing stock mean many chimneys were originally designed for coal or early oil furnaces before being converted to gas. That leaves unlined or improperly adapted flues creating serious draft and creosote hazards unique to this era of Pittsburgh-area construction. We’ve been driving out to Greentree from our Philadelphia base for over 42 years, and we know the difference between a chimney that needs a liner and one that needs a full rebuild before we even set up the ladder.
Why Hearthstone Chimney Co. of Philadelphia Is Greentree’s Preferred Chimney Liner & Rebuild Company
Our reputation in Greentree was built one brick ranch at a time. Homeowners here talk to neighbors on streets like Greentree Road and Mansfield Avenue, and word travels when a crew shows up on time, keeps the driveway clean, and explains what they found in plain English. We’ve earned strong reviews from Greentree customers who mention specifically that we photographed the inside of their flue, showed them the damage, and gave them a written estimate with no pressure.
Response time to Greentree matters, especially once October hits and the freeze-thaw cycle starts biting. We typically schedule liner inspections within 2-3 business days, and rebuild assessments within 48 hours when masonry damage has created an active safety concern. Our technicians know the local pattern: short chimneys on hillside streets backing up to I-279, original clay tile that’s crumbled after six decades, gas inserts shoved into flues never meant for them. That local knowledge saves you a diagnostic visit and gets the job scoped correctly from the start.
We’re not a one-truck operator who might answer the phone next month. We’re not a chain that sends a salesperson before a technician. We’re our Chimney Liner & Rebuild team - background-checked, uniformed, and carrying the 90-Day Done Right Promise in writing, no arguing.
Our Chimney Liner & Rebuild Services in Greentree
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most Greentree homes with deteriorated original clay tile. We install DuraFlex and Olympia Chimney stainless systems that handle gas, oil, or wood combustion and come with manufacturer warranties we honor directly. In Greentree’s 1940s-1960s brick ranches, we often find the original flue was sized for coal and is now dangerously oversized for a gas insert, which causes sluggish draft and condensation that rots the chimney from the inside. A properly sized stainless liner corrects the flue geometry and brings the system up to current NFPA 211 standards. Most Greentree stainless liner jobs run $2,200-$3,800 and finish in a single day.
Flexible Liner Installation
Flexible liners solve the offset and bend problems common in Greentree’s older chimneys, where decades of settling have shifted flue passages out of plumb. We use DuraFlex flexible stainless for offsets up to 45 degrees, which matters in split-level homes where the chimney chase zigzags between floor levels. Flexible installation avoids the costly masonry opening that rigid pipe sometimes requires. For Greentree homeowners with original construction chimneys that have settled along with the hillside terrain, flexible liner is often the difference between a $2,500 fix and a $6,000 rebuild. Typical range in Greentree: $2,000-$3,400.
Liner Replacement
When an existing liner has failed - cracked clay tile, corroded corrugated metal from a 1980s installation, or a HeatShield coating that’s reached end of life - we extract and replace. In Greentree, we see a lot of “liner” jobs that aren’t liners at all: a previous owner poured vermiculite down the flue and called it done. That doesn’t count. We remove the old material, inspect the full chimney structure with our Level-2 camera, and install a proper listed liner system. Replacement jobs in Greentree typically fall between $2,400-$4,200 depending on flue height and access.
Partial Chimney Rebuild
Western Pennsylvania’s pronounced freeze-thaw cycle - with Pittsburgh-area winters regularly oscillating above and below 32°F - accelerates spalling and mortar joint failure in the exposed masonry chimneys common throughout Green Tree. When the top courses of brick are crumbling or the crown has cracked through, a partial rebuild restores structural integrity without the cost of tearing down to the roofline. We rebuild with matching brick where possible and pour a new concrete crown with proper overhang and drip edge. Greentree partial rebuilds typically run $3,200-$5,500. We document the damage with photos you can see, explain the verdict in plain English, and give you upfront pricing before any mortar gets mixed.

Trusted Brands We Service in Greentree
We don’t use builder-grade substitutes. Our Greentree trucks stock DuraFlex flexible liners, HeatShield cerfractory resurfacing mix, and Gelco stainless components for same-day repairs when the diagnosis allows. For rebuilds, we source matching brick through Copperfield supply houses and use Famco termination caps when the original has rusted through. That parts availability matters in Greentree, where a specialty fitting for a 1950s chimney can otherwise add a week to the job. We choose brands that have been in the field long enough to prove themselves - no experiments on your home.
Common Chimney Liner & Rebuild Problems We See in Greentree Homes
- Unlined flues from original coal furnaces. Many Greentree homes were built with clay tile sized for coal combustion, then converted to gas without proper relining. The oversized flue cools too quickly, causing condensation and rapid creosote buildup that a standard cleaning won’t fix.
- Freeze-thaw masonry damage. Greentree’s exposed chimneys take the full force of Allegheny County’s winter temperature swings. Water enters hairline cracks, freezes, expands, and spalls off brick faces. Annual inspection catches this before partial collapse requires rebuild.
- Short chimneys on I-279 hillside streets. Homes along the hillside streets backing up to I-279 often have chimneys that are shorter relative to the steep roofline pitch than code would require today. This creates chronic downdraft problems that push smoke back into living spaces and accelerate glazed creosote buildup.
- Improper gas insert retrofits. A 1960s split-level with an unlined flue and a modern gas insert is a common Greentree combination we encounter. The insert runs efficiently, but the flue can’t handle the cooler exhaust temperatures, leading to corrosive condensation and hidden deterioration.
Pricing for Chimney Liner & Rebuild in Greentree, PA
Here’s what Greentree homeowners actually pay for chimney liner and rebuild work:
| Service | Typical Range in Greentree |
|---|---|
| Stainless steel liner (single flue, standard height) | $2,200 - $3,800 |
| Flexible liner with offsets | $2,000 - $3,400 |
| Liner replacement (remove old, install new) | $2,400 - $4,200 |
| Partial rebuild (top 3-5 feet + crown) | $3,200 - $5,500 |
| Full chimney rebuild | $6,500 - $12,000 |
| Level-2 camera inspection with report | $250 - $350 |
What moves the number? Flue height matters - a two-story Greentree ranch with a tall chase costs more than a single-level split-level. Access matters - steep I-279 hillside roofs require additional safety rigging. The condition of the existing flue matters - a chimney full of collapsed clay tile takes longer to clear than one with intact but cracked lining. We give you the full price before we start, and that number doesn’t change. Call (866) 580-4069 for a free estimate - we’ll scope it with the camera, show you the photos, and write it down.

FAQs - Chimney Liner & Rebuild in Greentree
Yes - an unlined or improperly sized flue is a safety hazard for any gas insert, and Greentree’s coal-era chimneys are almost always oversized for modern gas equipment. The original flue was designed for the high temperatures and strong draft of coal combustion; gas exhaust is cooler and wetter, so it condenses in the oversized passage, corroding masonry and creating creosote hazards. We install DuraFlex or Olympia Chimney stainless liners sized specifically for your insert’s BTU output and venting requirements. Call (866) 580-4069 - we’ll camera the flue and give you a written recommendation.
Most Greentree relining jobs run $2,000-$4,200 depending on liner type, flue height, and whether we need to clear collapsed original material first. A straightforward stainless liner in a single-story ranch with good access sits at the lower end; a flexible liner through multiple offsets in a hillside split-level with a full clay-tile collapse runs higher. We don’t guess - we camera first, then quote. Estimates are free.
It can be, but it’s often a combination of short chimney height relative to your steep roofline and an unlined flue that can’t generate adequate draft. On a hillside street backing up to I-279, we relined a short, steep-pitch chimney for a 1950s brick ranch homeowner who complained of smoke backing into the living room each winter. The original unlined flue had glazed creosote from decades of gas insert use, so we installed a DuraFlex stainless steel liner to fix the dangerous downdrafts and bring the chimney up to modern code. Sometimes we also need to extend the chimney height or add a proper termination cap. We’ll diagnose which applies to your home - call for a free inspection.
Yes - partial rebuild is one of our most common Greentree services, especially for 1940s-1960s homes where freeze-thaw damage has spalled the top courses of brick or cracked the crown. We rebuild from the damage point upward with matching brick, pour a new concrete crown with proper drainage, and install a termination cap that keeps water out. Most partial rebuilds in Greentree finish in 1-2 days and cost $3,200-$5,500. We photograph everything before and after, and the work is covered by our 90-Day Done Right Promise in writing.
We install DuraFlex flexible stainless, Olympia Chimney rigid stainless, and HeatShield cerfractory resurfacing systems in Greentree - all professional-grade, all listed to UL 1777. We don’t use generic or unlisted products. For rebuilds and repairs, we source Gelco components, Famco caps, and Copperfield supply materials.
