Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterDuraFlex Chimney Cleaning in Amity, PA | Hearthstone Chimney Co.
Amity Chimney Cleaning & Sweep with DuraFlex liner service typically runs $180-$340 for a standard sweep and inspection, with full liner installations starting around $1,800 depending on flue height and access. We’re an independent DuraFlex specialist, not a manufacturer-authorized dealer, which means we source genuine OEM parts and compatible aftermarket components based on what your chimney actually needs, not what a corporate parts program pushes. If your Amity home has one of those oversized coal-era flues common off Scenery Hill or near Manatawny Street, call (610) 819-4281 - we’ll inspect it with a camera and tell you straight whether a DuraFlex liner is the right fix.
Why Amity Residents Choose Us for DuraFlex Service
Russell Haines has spent the better part of two decades running sweeps and inspections across Washington County, including plenty of older homes near Manatawny Street where the chimneys are as stubborn as they are historic. He learned the fundamentals at Los Angeles Trade-Technical College, then put in years of field work before the craft became second nature. These days he’s known around Montgomery County for reading a flue quietly, carefully, and without missing much. We bring that same eye to every Amity service area call.
We’re not a manufacturer-authorized DuraFlex dealer. We’re better than that - we’re independent. That means when we recommend a DuraFlex 316L stainless liner or a new top plate, it’s because your flue measurements and camera footage say so, not because a distributor’s quarterly quota says so. Our technicians are background-checked, uniformed, and carry genuine DuraFlex OEM components for critical connections alongside quality aftermarket caps and insulation kits that meet or exceed OEM specs. Most jobs finish in a single visit. The number on your estimate is the number on your invoice. And everything we do carries our 90-Day Done Right Promise - in writing, no arguing.
The chimney does not lie - and neither do we.
Common DuraFlex Chimney Cleaning Problems We Solve in Amity
- Corrosion at seam welds and top terminations - Amity’s coal-era chimneys vented sulfur-heavy bituminous fuel for decades, leaving acidic residue that accelerates 304L alloy corrosion at DuraFlex seam points. We inspect these with a Level 2 camera and replace compromised sections with 316L where the flue environment demands it.
- Compression and kinking in oversized flues - Those original 12×12 or larger coal flues in pre-1960s Amity farmhouses give a flexible liner too much room. Without proper centralizing supports, the DuraFlex settles into an S-curve that restricts draft and traps creosote at the low point. We measure, support, and verify straight runs before we leave.
- Insulation wrap failure from crown or cap leaks - Southwestern Pennsylvania’s wet winters and brutal freeze-thaw cycling find every crack in a chimney crown. Water saturates DuraFlex’s wrap or pour-in insulation, creating hot spots and reducing efficiency. We replace damaged insulation and fix the water entry point so it stays fixed.
- Appliance connector corrosion in unlined gas conversions - Amity sits in one of Pennsylvania’s most active Marcellus Shale counties, and gas insert installations have surged. A gas insert vented into an unlined oversized flue without a proper DuraFlex adapter tee corrodes the connector and snout from condensing exhaust. We see this constantly. We fix it with correctly sized liners and supported connections.
- Downdraft and spillage from flue-oversizing - A small gas appliance in a massive coal flue behaves like a straw in a bucket. The draft never establishes properly, and exhaust spills into the living space. Our Level 2 inspection documents the mismatch; our DuraFlex liner installation fixes it with a flue sized to the appliance, not the fireplace opening.
DuraFlex Service in Amity: What Local Conditions Mean for Your Equipment
Last winter, we were called to a farmhouse off Scenery Hill in Amity where the homeowner had just installed a gas log set into the original coal fireplace. The flue was a massive 12×12 unlined brick shaft, and the small gas insert was losing draft and spilling exhaust smell into the room. We ran a Level 2 inspection, then installed a 3-inch DuraFlex stainless liner with a top plate and cap, sealed the damper area, and the downdraft and odor issues disappeared immediately.
This is the Amity pattern we see again and again. Many pre-1960s Amity homes still have their original oversized coal flues, often unlined or lined with deteriorated terra cotta. Dropping a modern gas insert into that flue without a correctly sized DuraFlex liner creates dangerous downdraft and condensation issues that mimic appliance problems but are actually chimney sizing failures. The Marcellus Shale boom has accelerated conversions here, and too many installers skip the liner step because the homeowner doesn’t know to ask, or because the installer doesn’t understand coal-era flue dynamics. We do. That’s why our DuraFlex sales & service starts with a camera inspection and a plain-English verdict - photos you can see, measurements you can verify, and a recommendation based on what your specific chimney requires.
DuraFlex Models & Products We Service in Amity
We work with the full DuraFlex product line: 316L and 304L stainless steel flexible chimney liner kits, insulated flexible liner systems with wrap or pour-in insulation, direct vent and gas vent liners for appliance conversions, and the complete component line including tees, caps, top plates, and appliance connectors. For critical connections and terminations, we stock genuine DuraFlex OEM components to ensure proper fit and safety. For caps and insulation kits, we’ll recommend quality aftermarket options when they meet or exceed OEM specifications and save you money without compromising performance. We keep common Amity sizes in stock - 3-inch, 4-inch, and 5-inch diameters for gas inserts, 6-inch and 8-inch for wood-burning appliances - so most Amity jobs don’t wait on parts.

FAQs - DuraFlex Chimney Cleaning in Amity
No - not without proper sizing, insulation, and support. A 3-inch or 4-inch gas insert in a 12×12 coal flue will draft poorly and may spill carbon monoxide into your home. We measure the appliance output, calculate the required flue diameter, and install a DuraFlex liner with proper centralizers and a sealed top plate. Call (610) 819-4281 for a free inspection and sizing calculation.
Water intrusion from cracked crowns or caps saturates insulation, then freezing expands and degrades it. We inspect for this every cleaning and Chimney Repair in Amity addresses the water entry point before it ruins the liner. Call (610) 819-4281 if you’ve noticed pieces of brick or mortar in your firebox.
Smell usually means exhaust spillage from poor draft, often caused by an oversized or unlined flue. Cleaning the appliance doesn’t fix a chimney sizing failure. Our Level 2 inspection identifies whether a DuraFlex liner is the correct solution. Call (610) 819-4281 - we’ll find the real source.
We always recommend repair when the liner is structurally sound and only a component has failed - a tee, a section of insulation, a corroded cap. We replace the full liner only when corrosion or physical damage compromises the entire system’s integrity. You’ll see the camera evidence either way before we recommend anything.
A Level 2 inspection first, then flue sizing to match your gas appliance, installation of a properly insulated DuraFlex direct vent or gas vent liner, sealing the damper area, and pressure-testing the connections. Most conversions complete in one day. Call (610) 819-4281 for a free estimate - we’ll walk through your specific setup.
