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.

Why Trust Hearthstone Chimney Co. for Your DuraFlex Chimney Cleaning?
We’ve swept and relined hundreds of DuraFlex chimney systems across Duraflex repair in Bedford and the surrounding Blue Ridge foothills. From older 316L setups to recent Pro Plus builds, we know which fittings, insulation wraps, and adapters hold up to the region’s humid summers and freeze-thaw winters. That knowledge comes from working on them, not from a certification seminar.
Russell Haines, our owner, came out of the trades program at Los Angeles Trade-Technical College with a clear sense of how work should be done and what it costs to cut corners. He’s spent the better part of two decades cleaning and inspecting chimneys across central Virginia, including older homes tucked along Daniels Hill where the masonry tells a long story. He’s known around Lynchburg for catching liner damage that other eyes have missed and for quoting a price he sticks to. When a homeowner says, “Tell me what you’re seeing, and I’ll tell you what it actually means,” we understand the bargain: plain facts, no theater.
Our technicians are background-checked and uniformed. Most jobs finish in a single visit. Every inspection ends with photos you can see and a plain-English verdict. The 90-Day Done Right Promise governs everything we do: Krafted right, Every time, Your home first, Standing behind it. In writing, no arguing.
Common DuraFlex Chimney Cleaning Problems We Fix in Lynchburg
- Corrosion pitting on 316L liner sections in damp basements. Lynchburg’s humid summers and the persistent morning moisture in the James River valley create conditions where a missing or undersized rain cap becomes expensive fast. Water tracks down the flue, pools at the tee or low spots, and begins pitting the 316L stainless from the inside out. We catch this with our camera before the liner is perforated through.
- Pro Plus insulation wrap tearing or compressing at bends. The DuraFlex Pro Plus 316L kit relies on continuous insulation to maintain safe clearances to combustibles. When that wrap tears at elbows or compresses in tight offsets, uninsulated hot spots develop. In Lynchburg’s older homes with balloon framing or lath-and-plaster chase walls, those hot spots endanger the structure and accelerate creosote glazing where the flue runs cooler.
- Liner seams separating or flexing at the appliance connector. Years of heat cycling, especially in wood-burning applications where the DuraFlex 304L or 316L sees wide temperature swings, loosen the connection between liner and appliance. Smoke spills into the basement or living space. Draft drops. The homeowner smells it before they see it.
- Clogged or reversed terminations from multi-flue cap corrosion. On steep-lot properties in Garland Hill and College Hill, hilltop wind exposure creates negative pressure that overwhelms short or uncapped stacks. A rusted-through multi-flue cap makes this worse, pulling smoke back down the flue and plastering creosote at the top of the DuraFlex run. We’ve had customers call for their third “cleaning” in two years when the flue was clean and the cap was the problem.
- Creosote odor after sweeping. When water intrusion combines with incomplete combustion in a marginal draft, creosote soaks into porous buildup or damaged insulation. A standard sweep removes the bulk, but the smell persists until the source, water entry, is stopped and any saturated insulation is replaced.
DuraFlex Parts & Our Repair-vs-Replace Approach
We stock genuine DuraFlex 316L and Pro Plus components: tees, elbows, top plates, caps, and adapters. When OEM lead times stretch or a part is discontinued, we use only UL-1777-listed aftermarket insulation and adapters that match the specification. No builder-grade substitutes.
Our rule is straightforward. If a liner is lightly rusted or has one failed fitting, we reline the section and replace the damaged component. If multiple sections are pitted through, if the insulation is saturated and compressed along most of the run, or if the original installation used 304L where 316L was needed for the appliance type, we recommend a full Pro Plus replacement. Piecemeal patches on a failing system cost more over five years than doing it right once. We’ll show you the camera footage and explain which path makes sense for your chimney and your budget.

Our DuraFlex Service Process - Step by Step
- 1
Diagnosis with Level 2 camera inspection. We run a high-resolution camera the full length of your DuraFlex liner, documenting seams, insulation condition, corrosion patterns, and creosote buildup density. You see the photos. We explain what they mean for draft, safety, and remaining service life.
- 2
Repair or install with DuraFlex-compatible components. Based on the findings, we sweep, replace caps or fittings, reline sections, or install a new Pro Plus 316L kit. Every part we use is spec-matched to your system.
- 3
Draft and pressure testing. We verify performance with a manometer, checking that draft falls within normal range for your appliance type and chimney height. On DuraFlex systems in Lynchburg’s hilltop neighborhoods, we pay particular attention to wind-induced pressure variations.
- 4
Documentation and warranty. You receive photos, a written verdict, and the 90-Day Done Right Promise. If it’s not right, we make it right. No paperwork to find, no argument to have.
DuraFlex Products We Service & Install in Lynchburg
We work with the full DuraFlex flexible liner range: 316L stainless for oil and gas applications and heavy wood-burning use; 304L for standard wood-burning fireplaces and inserts; Pro Plus 316L and 304L kits with factory insulation and UL 1777 listing; and Crown and Cap adapters for proper termination and weather protection. For DuraFlex Chimney Cleaning in Timberlake, VA and Lynchburg’s pre-1900 brick chimneys, especially the multi-flue structures common in Garland Hill and Rivermont, we frequently specify Pro Plus 316L to handle the combination of moisture intrusion risk and the clearances these narrow, unlined flues demand.
We keep common DuraFlex fittings and caps on our trucks. Most repairs don’t wait for shipping.
We Also Service These Brands
Hearthstone Chimney Co. is not a single-brand shop. We service and install HeatShield refractory repair systems for cracked clay flue tiles, Gelco chimney caps and accessories, and liners and components from Olympia Chimney, Famco, and Copperfield. If your chimney has a mix of brands from previous repairs, we know how they interface and what to watch for.
FAQs - DuraFlex Chimney Cleaning Service in Lynchburg
No. We are an independent DuraFlex service provider with no manufacturer authorization or affiliation. Our expertise comes from field experience across hundreds of DuraFlex installations and repairs in the Lynchburg area, not from a dealer program.
Failing liners show pitting, thinning, or perforation visible on camera, often concentrated at the tee or low points where water collects. A liner that merely needs sweeping will have intact metal with surface creosote or soot that brushes clean. If you’re seeing rust flakes in the firebox or smelling damp metal, that’s liner failure, not dirty flue. Call (540) 328-6986 and we’ll show you the difference on camera.
It matters more here than in drier markets. Lynchburg’s freeze-thaw cycles and humid summers mean condensation inside the flue is constant. Uninsulated or poorly insulated liners run cooler, condense more moisture, and glaze creosote faster. The Pro Plus wrap maintains temperature, reduces condensation, and protects clearances in the older, tighter chase walls common in Diamond Hill and Rivermont homes.
Usually, yes. If the liner itself is sound and the damage is limited to the cap, top plate, or storm collar, we replace those components from the top. We verify liner condition with a quick camera run before we close up. If the cap failed because of liner movement or corrosion at the top joint, we’ll tell you and show you why.
The sweep removed loose buildup, but creosote has soaked into damaged insulation, corrosion pits, or porous masonry where water has been entering. Until the water source is fixed and any saturated materials are replaced, the smell returns with humidity changes. In Lynchburg’s river-valley climate, this is a common pattern we trace to cap failure or top-plate leaks.
For occasional fireplace use, 304L is acceptable. For a wood stove or insert that burns daily through the heating season, we recommend 316L. The higher alloy resists the acidic condensates and higher burn temperatures that central Virginia’s long wood-burning season produces. If you’re converting an old coal flue in a Garland Hill Victorian back to wood, 316L Pro Plus is what we’d quote.
A standard DuraFlex sweep and Level 2 inspection runs $89 during our seasonal tune-up period. Repairs, cap replacements, or partial relines depend on access height, liner diameter, and the extent of damage we find. We quote upfront before any work begins.
