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 Delaware, NJ | Hearthstone Chimney Co.
Chimney Cleaning & Sweep in Delaware for DuraFlex systems typically runs $180-$340 for a standard sweep and Level 2 inspection, with most jobs completed in a single visit. What makes our DuraFlex work here different is the concentration of 18th- and 19th-century farmhouses with original unlined fieldstone flues and aging first-generation flexible liners that other sweeps miss entirely. We are an independent chimney contractor, not a DuraFlex dealer or authorized agent, and we base every recommendation on what your flue actually needs. Call (856) 388-5580 for a free estimate.
Why Delaware Residents Choose Us for DuraFlex Service
Russell Haines and our crew have been cleaning and inspecting chimneys throughout Delaware and across the Ewing Lawrence border along Bear Tavern Road for well over a decade. Some of those customers are now on their second generation of calling us in before the cold sets in. We know how DuraFlex stainless components behave in the field because we have pulled, swept, and reinstalled them in the exact conditions Delaware presents: original unlined stone flues, improvised wood-stove retrofits, and freeze-thaw cycles that punish mortar joints.
We use genuine DuraFlex stainless liner components, caps, and top plates when replacement matches the existing system, and quality aftermarket connectors for standard adapters. Every Level 2 inspection ends with photos you can see and a plain-English verdict. Our 90-Day Done Right Promise is in writing, no arguing. If the flue is right, the fire takes care of itself.
A live person answers our phone 24 hours a day, 7 days a week. Not a voicemail. Not a callback queue. Background-checked, uniformed technicians. No-hassle upfront pricing. The number on the estimate is the number on the invoice.
Common DuraFlex Chimney Cleaning Problems We Solve in Delaware
- Creosote glazing on flexible liner walls. Delaware’s heavy wood-burning winters mean Stage 2 and Stage 3 creosote builds fast, especially when an undersized DuraFlex liner was fitted to a wood stove in an old wide fireplace flue. The restricted draft traps deposits that a standard brush won’t touch. We use rotary whipping systems designed for corrugated stainless walls.
- Corrosion at the bottom of 316 and 304 liners. Oil and propane appliances venting through Delaware chimneys produce acidic condensate that pools above masonry smoke chambers with no liner insulation. We inspect the lower liner section with a camera and replace pitted components rather than selling you another season on borrowed time.
- Compressed or creased corrugations. DuraFlex flexible liner pulled through an offset or unlined stone flue in a Delaware farmhouse often hangs up on jagged mortar shelves. Soot clings to the damaged ridges. Our field vignette from Route 519 is one example among many. We map the damage before deciding whether sweeping is safe or replacement is the honest call.
- Failed top-plate and cap connections. Western New Jersey’s freeze-thaw cycling opens mortar joints and lets water run down the outside of the liner, rotting terminations from above. We find this on Delaware chimneys every spring. A new top plate without addressing the masonry is a waste of your money, and we will tell you so.
- Improper stovepipe connections from old retrofits. Many Delaware farmhouses were converted from open hearths to wood stove inserts with jury-rigged thimbles and cleanout-door penetrations. A DuraFlex liner sized for a wide-open fireplace cannot properly vent an airtight stove. We measure the appliance, the flue, and the liner together.
DuraFlex Service in Delaware: What Local Conditions Mean for Your Equipment
Because most properties in Delaware, NJ sit off the natural gas grid, a large share of homes heat with wood, pellet, or oil, and we routinely pull DuraFlex liners that were installed decades ago as the area’s first wave of wood-stove retrofits. Those early flexible liners are now reaching the end of their service life at the same time we are finding original unlined fieldstone flues behind them that never got a proper masonry repair before the liner went in. This is not a theoretical problem. On a farmhouse along Route 519 in Delaware, we opened a 1980s-era DuraFlex Flex 316 liner that had been dropped into an original unlined fieldstone flue and found the bottom three feet crushed against a jagged mortar shelf, with Stage 3 creosote glazed across the corrugations. After a Level 2 inspection confirmed the flue was choked, we swept out the liner and turned to our Chimney Repair in Delaware to rebuild the damaged smoke chamber shelf with new masonry, and reinstalled an insulated DuraFlex Pro 316Ti liner sized to the homeowner’s airtight wood stove. The stove drafted immediately on the first test fire, and the owners are now set for the winter without pulling creosote through their living room.
This pattern is specific to Delaware’s rural housing stock. Newer suburban construction does not face it. That is why a generic sweep is not enough here.

FAQs - DuraFlex Chimney Cleaning in Delaware
Schedule a Level 2 camera inspection. We need to see whether the liner was installed with proper insulation, whether the stone flue behind it has shifting mortar or missing shelves, and whether the liner itself shows corrosion, crushing, or open seams. Many Delaware farmhouses have liners that were dropped in decades ago over damaged masonry. Cleaning alone will not fix that. Call (856) 388-5580 to book before burning season.
Yes, when the corrugations are intact and the liner is properly supported. We use polypropylene whips and controlled-speed rotary equipment, not steel brushes that can catch and tear. If the liner is already crushed or creased, we stop and show you the camera footage. Sweeping a damaged liner can make it worse. We will not do that.
The sweep may have missed glazed deposits, or the liner may be undersized for your stove. In Delaware’s old farmhouses, we often find DuraFlex liners installed in flues that were never properly resized when an airtight stove replaced an open fireplace. The restricted draft keeps creosote forming even after brushing. A camera inspection reveals which problem you have. Call (856) 388-5580 and we will sort it out.
It depends on the masonry condition. If the stone shell is sound and the mortar joints are repairable, a properly insulated DuraFlex Pro 316Ti liner is a safe, cost-effective solution that can last decades. If the chimney is structurally failing, rebuilding may be the honest recommendation. We give you the camera evidence either way. No guesswork. No upsell.
Pitting, open seams, crushed corrugations, or corrosion holes visible on camera mean replacement. We show you the footage and explain what we see. A liner that is merely dirty gets swept. A liner that is failing gets replaced. The difference is not a matter of opinion; it is visible evidence you can see for yourself. Call (856) 388-5580 for a free inspection.
