We’ve been working in the South Hills of Allegheny County for over 42 years, and Greentree is familiar territory. The borough’s post-war ranches and split-levels along streets like Mansfield Avenue and Forest Drive present chimney problems we recognize before we even park the truck. Short chimneys on steep rooflines. Coal-era flues pressed into gas service. Freeze-thaw damage that opens mortar joints every spring. Our Chimney Cleaning & Sweep team knows what to look for, and we document everything with photos you can see and a plain-English verdict.
Why Hearthstone Chimney Co. of Philadelphia Is Greentree’s Preferred Chimney Cleaning & Sweep Company
We earned our reputation in Greentree the same way we earned it everywhere else: by showing up when we say, explaining what we found without jargon, and standing behind the work. Carl Bridwell built this company in 1984 on the principle that a craftsman doesn’t need to oversell - the work speaks, and the guarantee backs it up.
Greentree homeowners call us because we’ve seen their exact house before. The 1950s brick ranch with the original clay-tile flue. The split-level on the hillside where the chimney terminates three feet below the ridge line and smoke rolls back into the family room every time the wind shifts. These aren’t hypotheticals. They’re patterns we know from decades in Allegheny County.
Our phones are staffed by a live person 24 hours a day, 7 days a week - not a voicemail, not a callback queue. Most jobs are completed in a single visit. Our technicians are background-checked, uniformed, and trained to document every inspection with photographs and a written verdict. The estimate we give is the invoice we send. No surprises on the bill.
Every job carries our 90-Day Done Right Promise - the Keystone Standard - in writing with no arguing. If it’s not right, we come back. That’s how a company that plans to be here in thirty years acts.
Our Chimney Cleaning & Sweep Services in Greentree
Level 1 Inspection
A Level 1 inspection is the baseline annual check for chimneys that haven’t changed and are performing normally. In Greentree, we recommend this for homeowners who’ve already addressed any known flue issues and are staying current. We examine the readily accessible portions of the chimney exterior, interior, and connection, checking for obstructions, creosote buildup, and basic structural soundness. For the borough’s older housing stock, though, a Level 1 is often just the starting point.
Level 2 Inspection
This is where we do our best work in Greentree. A Level 2 inspection includes everything in Level 1 plus a camera scan of the entire flue interior - critical for the unlined or improperly adapted chimneys common in post-war ranches and split-levels throughout ZIP 08003. We document every foot with photos you can see, and we deliver a plain-English verdict on what we found.
On a cold October morning, we climbed the roof of a 1950s brick split-level on Mansfield Avenue and found a classic Greentree problem: an unlined chimney originally built for coal, later retrofitted for a gas insert with a flue liner that had separated five feet down. The homeowner had smelled smoke for weeks. We cleaned out two inches of glazed creosote, installed a new HeatShield liner, and restored proper draft. Without a Level 2 camera inspection, that separation would have stayed hidden until it became dangerous.
Creosote Removal
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 Greentree. Cracked mortar lets cold air infiltrate, cooling the flue and causing incomplete combustion. The result is glazed creosote, a hard, tar-like deposit that standard brushing won’t remove.
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, creating chronic downdraft problems that push smoke back into living spaces and accelerate glazed creosote buildup - a pattern local sweeps recognize immediately in this part of the borough. We remove glazed creosote with mechanical rotary systems, not shortcuts, and we identify the root cause so it doesn’t return.
Soot Removal
Soot is the softer, powdery byproduct of complete or near-complete combustion, and it accumulates in every chimney. In Greentree’s gas-converted systems, we often find soot mixed with corrosive condensation from flue gases cooling too quickly in oversized or unlined flues. We remove it completely and check for the flue-sizing problems that cause it.
Annual Sweep
An annual sweep is the single most important maintenance step for Greentree homeowners, and October is the critical month. The freeze-thaw cycle has done its damage over the winter; spring rains may have entered through cracked crowns; and the heating season is about to begin. We schedule Greentree sweeps with enough time to address any repairs before the first hard cold. The $89 Seasonal Tune-Up covers the sweep and basic inspection - call (866) 580-4069 to book.
Fireplace Cleaning
Fireplace cleaning addresses the firebox, smoke chamber, and hearth - the visible portions that affect both safety and appearance. In Greentree’s older homes, we often find degraded firebrick and damaged smoke chamber walls that need attention before the flue itself can function properly.

Trusted Brands We Service in Greentree
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, HeatShield, and Famco - the brands that other sweeps in the Pittsburgh area call us to source. For Greentree homeowners, that means no waiting on special orders for liner components, no jury-rigged repairs with whatever was in the van, and no callbacks because a part failed prematurely. When we installed that HeatShield liner on Mansfield Avenue, we had the materials on the truck. Done right - and we stand behind it.
Common Chimney Cleaning & Sweep Problems We See in Greentree Homes
- Unlined or improperly adapted flues from coal-to-gas conversions. 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 - leaving unlined or improperly adapted flues that create serious draft and creosote hazards unique to this era of Pittsburgh-area construction. A Level 2 inspection finds what a visual check cannot.
- Spalling and mortar joint failure from freeze-thaw cycles. Western Pennsylvania’s winters regularly oscillate above and below 32°F, and exposed masonry chimneys throughout Greentree absorb moisture, freeze, expand, and crack. Annual inspection catches this before it becomes structural.
- Chronic downdraft from short chimneys on steep rooflines near I-279. 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, creating chronic downdraft problems that push smoke back into living spaces and accelerate glazed creosote buildup - a pattern local sweeps recognize immediately in this part of the borough.
- Glazed creosote in gas-retrofit systems. The combination of cool, oversized flues and incomplete combustion produces hard, glazed creosote that requires mechanical removal. Standard wire brushing won’t touch it.

FAQs - Chimney Cleaning & Sweep in Greentree
Your chimney was likely built for coal or oil and was never properly relined for gas, or the liner has separated. Gas inserts require a correctly sized, continuous flue liner to maintain adequate draft temperature; without one, combustion gases cool too quickly, lose buoyancy, and roll back into your living space. In Greentree’s hillside ranches near I-279, this combines with short chimneys on steep rooflines to create chronic downdraft. We find this exact scenario with our Level 2 camera inspection, then correct it with proper relining - HeatShield or DuraFlex, depending on your flue condition. Call (866) 580-4069 for a free estimate.
Once per year, every year, ideally in September or October before the heating season begins. Western Pennsylvania’s freeze-thaw cycle accelerates mortar and masonry damage, and spring rains may have entered through cracks you cannot see from the ground. Annual sweeping removes creosote and soot while the inspection catches freeze-thaw damage before it worsens. We schedule Greentree appointments to complete repairs before the first hard cold. Call (866) 580-4069 to book your annual sweep.
Efflorescence - mineral salts leaching from masonry as moisture moves through the brick and evaporates. In Greentree, it’s common on chimneys with failed crowns or open mortar joints from freeze-thaw damage. The white crust itself is cosmetic, but the moisture causing it is not. It indicates water intrusion that will eventually spall brick, rot adjacent framing, and deteriorate the flue liner. We identify the water entry point during inspection and repair it at the source - crown sealing, mortar repointing, or cap replacement with Copperfield or Famco components. Call (866) 580-4069 for an inspection.
Yes. Short chimneys on steep rooflines, common along Forest Drive and other hillside streets backing I-279, frequently terminate below the pressure zone created by wind moving across the roof ridge. This causes chronic downdraft that pushes smoke into living spaces and cools the flue, accelerating glazed creosote buildup. Current code would require greater height; existing chimneys may need a draft-inducing cap or extension to perform safely. We measure, diagnose, and correct this pattern regularly in Greentree. Call (866) 580-4069 for a Level 2 inspection with full documentation.
