Why Hearthstone Chimney Co. of Philadelphia Is Fort Washington’s Preferred Chimney Cleaning & Sweep Company
Fort Washington homeowners don’t call us because we’re the cheapest. They call because we’ve been here long enough to understand what “cheap” costs when a sweep misses a cracked crown or a combined flue that’s been dumping carbon monoxide into the wall cavity since the Truman administration. Over 42 years, we’ve cleaned chimneys on Susquehanna Road, along Fort Washington Avenue, and in the quiet lanes off Skippack Pike where the pre-WWII fieldstones sit back among oak and sycamore.
Our technicians are background-checked, uniformed, and trained to document every inspection with photos you can see and a plain-English verdict. Most jobs finish in one visit. Our pricing is upfront: the number on the estimate is the number on the invoice. And every job carries the 90-Day Done Right Promise in writing, no arguing - if it’s not right, we come back.
We also answer the phone. A live person, 24 hours a day, 7 days a week. Not a callback queue. Not an app.
Our Chimney Cleaning & Sweep Services in Fort Washington
Level 1 Inspection
A Level 1 inspection is the baseline for any Fort Washington chimney that’s been in regular use and hasn’t undergone major changes. We examine the readily accessible portions of the chimney exterior, interior, and connection - checking for creosote buildup, obstructions, and basic structural soundness. For newer homes in Fort Washington, this is often sufficient. For the 1910s-1950s stone and brick colonials that dominate Whitemarsh Township, it’s almost never enough on its own.

Level 2 Inspection
Level 2 is where we earn our keep in Fort Washington. Using a high-resolution camera, we inspect every surface of the flue liner, the smoke chamber, and the chimney interior - the parts you cannot see from the hearth or roof. This is non-negotiable for homes with combined flues, corbeled flue throats, or any chimney that’s experienced an operating problem, a change of appliance, or a significant weather event. On a Chestnut Hill Lane colonial built in 1924, we found an original combined flue serving both the fireplace and a converted oil furnace; the clay liner was only 6×8 inches, causing a cross-draft that kept pushing smoke into the living room. We installed a HeatShield liner sized for the fireplace alone and capped the furnace flue with a Gelco offset adapter. Without the camera, that problem stays hidden until someone gets sick or the wall smolders.

Creosote Removal
Fort Washington’s dense tree canopy, especially in the neighborhoods bordering the Wissahickon Valley corridor, creates a microclimate that keeps chimneys cooler longer into the burning season. Cooler flue temperatures mean incomplete combustion, which means glazed creosote - the hard, tar-like deposit that standard wire brushes won’t touch. We use professional-grade mechanical whips and, when necessary, chemical treatments to break down Stage 3 creosote without damaging original clay liners. This is not a job for a hardware-store brush and a shop vac.

Soot Removal
Soot is the softer, powdery byproduct of efficient combustion, but in Fort Washington’s older chimneys it often mixes with decades of fallen mortar, animal nesting, and leaf debris from those overhanging oaks. We remove it completely, using HEPA-contained vacuums so nothing settles into your living room. For homes with original coal-to-oil conversion furnaces still venting through the chimney, soot removal also reveals whether the flue is properly sized for the current appliance - a common mismatch we find in pre-WWII construction.

Annual Sweep
The National Fire Protection Association recommends annual inspection and sweeping for all wood-burning systems. In Fort Washington, we’d add: if your home was built before 1940, consider the annual sweep non-negotiable. The soft historic brick and lime mortar common here deteriorates faster under the stress of dozens of freeze-thaw cycles each winter. A clean flue is a dry flue. A dry flue freezes less destructively. It’s that simple.

Fireplace Cleaning
Fireplace cleaning in Fort Washington addresses the firebox, smoke shelf, and hearth - the areas where ash, soot, and creosote accumulate where you can see them. We clean these surfaces thoroughly, but we also check what you cannot see: whether the smoke chamber narrows dangerously, whether the damper seals, and whether the hearth depth meets modern clearances. Many original Fort Washington fireplaces were built for coal grates, not wood logs, and the geometry is wrong for modern use.

Trusted Brands We Service in Fort Washington
We don’t use builder-grade substitutes. For liner installations and repairs in Fort Washington, we specify DuraFlex stainless steel liners, HeatShield cerfractory flue resurfacing, and Gelco chimney caps and fittings. For exterior repairs and crown work, we source through Copperfield and Olympia Chimney. These are the brands that professional sweeps specify when the job has to last. We keep common sizes and fittings in stock, so most Fort Washington repairs don’t wait on a parts truck from out of state.
Common Chimney Cleaning & Sweep Problems We See in Fort Washington Homes
- Combined flues cause persistent smoke drafting problems. The fireplace and furnace flues share a single stack, a configuration standard in pre-WWII Montgomery County construction. Sweeps who don’t inspect both flues miss the root cause entirely. We camera both every time.
- Original lime mortar joints fail after freeze-thaw cycles. The Philadelphia region’s winter pattern puts Fort Washington through dozens of freeze-thaw cycles per season, which is especially damaging to soft historic brick and lime mortar. A routine sweep clears debris but never seals the joints. We flag deterioration and recommend crown sealing or repointing before water enters the wall system.
- Corbeled flue throats without dampers make standard Level 2 inspection impossible. The camera cannot navigate the corbel, so creosote buildup goes unseen. We use specialized flexible cameras and articulating heads to inspect these antique configurations, or we recommend a smoke chamber parge when access is too restricted.
- Heavy autumn leaf-and-debris accumulation blocks chimney tops. The dense tree canopy in neighborhoods bordering Fort Washington State Park and the Wissahickon Valley corridor dumps leaves, twigs, and squirrel nests into uncapped flues every October. A seasonal sweep in September prevents the chimney becoming a compost heap by Thanksgiving.

FAQs - Chimney Cleaning & Sweep in Fort Washington
You likely have a combined flue or an undersized liner causing cross-drafting between the fireplace and a furnace or boiler vent. In Fort Washington’s pre-WWII homes, this is the most common cause of persistent smoke odor after a sweep. The sweep cleaned the flue, but it didn’t fix the geometry. We diagnose this with a Level 2 camera inspection and correct it with proper liner sizing or flue separation. Call (866) 580-4069 for an exact diagnosis - estimates are free.
Yes. Fieldstone chimneys in Fort Washington often have corbeled flue throats, no dampers, and rubble-stone interiors that standard inspection protocols cannot assess. We use specialized camera equipment and may recommend a Level 2 inspection with smoke chamber evaluation. The antique construction is beautiful, but it requires a sweep who understands pre-modern masonry. Call (866) 580-4069 to schedule - estimates are free.
Annually, at minimum, and we recommend inspecting both flues even if you only use the fireplace. The conversion furnace often vents through a flue never designed for its exhaust temperature and volume, accelerating liner deterioration and creosote accumulation in the shared stack. Fort Washington’s freeze-thaw cycles make this worse. Call (866) 580-4069 to set up a maintenance schedule - estimates are free.
Most cracked crowns in Fort Washington can be repaired with professional-grade crown sealant or a poured concrete overlay if the structural integrity is sound. Full rebuilds are only necessary when the crown has separated from the flue walls or when freeze-thaw damage has compromised the brick courses beneath. We document the condition with photos and give you a plain-English verdict. Call (866) 580-4069 for an inspection - estimates are free.
Install a properly sized chimney cap with mesh screening, and schedule your annual sweep for September before the heavy drop from Fort Washington’s oak and sycamore canopy begins. The neighborhoods bordering Fort Washington State Park and the Wissahickon Valley see the worst accumulation. A cap designed for your flue size and draft requirements, not a generic hardware-store model, is essential. Call (866) 580-4069 and we’ll measure and fit the right one - estimates are free.
