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 Roanoke, VA | Hearthstone Chimney Co.
Roanoke Chimney Cleaning & Sweep for DuraFlex liners typically runs $180-$340 for a standard sweep and Level 2 inspection, with most jobs completed in a single visit. We’re an independent chimney company - not affiliated with or authorized by DuraFlex - and we’ve installed and cleaned DuraFlex liners in hundreds of Roanoke Valley homes over the past four decades. The valley’s cold-air drainage and Victorian housing stock create liner problems you won’t find in Piedmont Virginia, which is why our sweeps camera-scope every flue before touching a tool.

Why Roanoke Residents Choose Us for DuraFlex Service
We’ve been working chimneys in the Roanoke Valley since 1984. Russell Haines, our owner, picked up the trade at Los Angeles Trade-Technical College before spending the better part of two decades on roofs from Grandin Road to Old Southwest. He and our crew have cleaned and inspected stacks along those streets as many times as some people change furnace filters. That kind of repetition teaches you things no classroom covers - like how to read a firebox the way a mechanic reads an engine, quietly and without drama.
We specify DuraFlex sales & service more than any other flexible relining system in Roanoke because it handles what this city’s old brick throws at it: oval flues, offset runs from coal-to-gas conversions, and undersized passages that newer liner systems simply won’t fit. Our technicians carry genuine DuraFlex 316L components on the truck, and our Level 2 inspections end with photos you can see and a plain-English verdict. The 90-Day Done Right Promise covers every job - in writing, no arguing. If it’s not right, we make it right.
Common DuraFlex Chimney Cleaning Problems We Solve in Roanoke
- Liner base corrosion from acidic condensate: Roanoke’s October-to-April burn season keeps liners wet and acidic far longer than Lynchburg or Charlottesville. DuraFlex 316L holds up well, but when a crown or cap has been leaking, we regularly find surface rust along the bottom 12-18 inches of the first section. We catch this during camera inspection and replace the affected length with new 316L before it pits through.
- Compression or kinking at offset bends: Old Southwest and Grandin Village chimneys have offset flue runs from original coal-to-gas conversions. A DuraFlex liner pulled through a tight offset can dent and restrict draft. That restriction accelerates creosote staging on the liner walls, which our annual sweeps remove before it becomes glazed.
- Liner-to-appliance connector gaps at the top plate: In multi-flue Victorian chimneys where one flue is still gas and another was switched back to wood, a DuraFlex liner dropped in the wood flue often doesn’t seal cleanly at the crown plate. Cold valley air and moisture drain down the annulus, rusting hardware and chilling the flue gas below the dew point.
- Crown and cap failure exposing the liner top: Our freeze-thaw cycling on the valley floor cracks crowns faster than homeowners expect. Once the top foot of a DuraFlex installation is exposed, the termination cap seal is the only thing keeping water off the stainless. We replace the crown and cap as part of the liner service when needed.
- Creosote staging in oversized flues: A DuraFlex liner sized correctly for a modern insert leaves less free volume than the original coal flue. In Roanoke’s extended cold season, that concentrated flue gas can stage creosote faster than homeowners anticipate. Annual sweeping prevents buildup that would otherwise require chemical treatment or mechanical removal.
DuraFlex Service in Roanoke: What Local Conditions Mean for Your Equipment
Roanoke sits in a bowl-shaped valley ringed by the Blue Ridge and Allegheny Mountains. Cold air drains onto the valley floor and stays there, pushing January lows well below what Piedmont Virginia cities experience and extending the active heating season from October through April. That sustained cold drives consistent fireplace and insert use, accelerating creosote staging to levels that make annual cleaning a practical necessity rather than a recommendation.
The compounding factor is the housing stock. Old Southwest, one of Virginia’s largest intact Victorian residential districts, is dense with original 1880s-1920s brick chimneys built for coal, later converted to gas, and now increasingly pressed back into wood-burning service without relining. We routinely encounter multi-flue stacks where one flue served a parlor fireplace and an adjacent flue served a coal furnace that was later capped. Homeowners have unknowingly burned wood in the capped or unconverted flue, sometimes sharing a deteriorated terra-cotta liner with a still-active gas appliance on the other side of the wythe.
That’s why our DuraFlex liner jobs in Roanoke start with camera-scoping every flue in a multi-flue stack before we assume we know which one the fireplace actually uses. A clean chimney doesn’t announce itself. Neither does a problem - until it does.
DuraFlex Models & Products We Service in Roanoke
We work with the full DuraFlex stainless relining line: the standard DuraFlex Stainless Steel Chimney Liner Kit in 316L, 6-inch and 8-inch diameters; DuraFlex 316L Flexible Relining Pipe in both round and oval profiles for the offset flues common in Roanoke’s conversions; the DuraFlex Insulated Liner Kit for exterior chimneys and unheated chase applications where valley cold would otherwise cool flue gas below the dew point; and the DuraFlex Pro Flexible Liner with termination cap for high-efficiency appliances.
We stock genuine DuraFlex liner components and termination parts because the stainless grade and wall thickness are the whole point of the system. No aftermarket copy matches the 316L spec. On caps, top plates, and connectors we’ll use quality aftermarket hardware when it’s a real upgrade - but if a liner is kinked, corroded through, or undersized for the appliance, we tell you straight that it needs to come out rather than patch over it.

FAQs - DuraFlex Chimney Cleaning in Roanoke
Most do. The original clay tile liners in Roanoke’s Victorian stock were sized for coal, not wood, and many have cracked or spalled after decades of gas conversion and disuse. Wood burns cooler and wetter than coal, producing acidic condensate that attacks damaged tile and mortar. A properly sized DuraFlex 316L liner protects the masonry and sizes the flue correctly for modern appliances. Call (540) 787-3302 and we’ll camera-scope yours to give you a straight answer.
Once per year, minimum. The extended burn season here - October through April, sometimes longer in a hard winter - stages creosote faster than in milder climates. We recommend scheduling before the first fire each fall. Call (540) 787-3302 to book your seasonal sweep.
Yes. We use polypropylene brushes sized to the liner diameter, never steel wire that can score the 316L surface. The flexible design of DuraFlex actually makes it easier to clean thoroughly than rigid pipe, since the brush follows every bend. Our technicians are trained to identify when a liner has corroded thin enough that brushing risks a breach - we switch to gentler methods and document what we find.
We can inspect and sweep both, but we clean them separately with dedicated equipment to prevent cross-contamination. In Roanoke’s old multi-flue chimneys, we also verify that each appliance is connected to the correct flue - we’ve found cases where a wood fireplace was venting into a flue still shared with a gas water heater. That’s a carbon monoxide risk we address immediately.
A kinked liner restricts draft and accelerates creosote buildup. We’ll camera-inspect to assess the severity. Minor dents sometimes can be smoothed; significant kinks or collapses require Chimney Repair in Roanoke with section replacement. We don’t patch over a liner that’s structurally compromised - we’ll show you the camera footage and explain whether repair or full replacement is the honest call.
