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.

How DuraFlex Products Fail - and How We Fix Them
- DuraFlex DVC vented gas fireplaces: delayed ignition and soot buildup. The DVC series uses a sealed combustion system that depends on precise gas-to-air ratio. In Lynchburg’s humid summers, the pilot assembly corrodes faster than in drier climates, causing delayed ignition that rattles the firebox and leaves soot on the faux logs. We pull the burner, clean the orifice with the correct DuraFlex gauge bit, and replace the pilot if the thermopile output has dropped below spec. We don’t guess - we test millivolt output before we quote.
- DuraFlex DW wood-burning inserts: creosote glazing in the flex liner. The DW insert line pairs with a flexible stainless liner that runs the full chimney height. When homeowners burn unseasoned oak from nearby Appomattox or Buckingham County, the liner develops a glazed creosote layer that standard brushes won’t touch. We use a rotary polypropylene whip system designed for .005″ corrugated DuraFlex liner, followed by a Level-2 camera inspection to confirm the flue is clean wall-to-wall.
- DuraFlex DFT direct-vent terminations: wind-driven downdraft and discolored glass. The DFT termination cap sits low-profile on the wall or roof, which works fine until a Lynchburg winter wind whips down from the Blue Ridge. The anti-recirculation baffle warps, pulling exhaust across the intake and fogging the glass permanently. We inspect the baffle geometry, replace with OEM DuraFlex or a tested equivalent, and reset the venting slope to minimum 1/4 inch per foot back to the unit so condensate drains properly.
- DuraFlex gas fireplace dampers: motor failure and stuck open/closed positions. Older DuraFlex units with the integrated motorized damper - common in 1990s and 2000s Lynchburg builds around Boonsboro and Wyndhurst - suffer from a known weak point: the actuator gears strip after roughly 15 years of heat cycling. A stuck-open damper wastes conditioned air year-round. We test the motor amp draw, and if the gearbox is shot, we source the correct DuraFlex replacement rather than jury-rigging a universal part that voids any remaining warranty.
- DuraFlex firebox refractory panels: cracking from thermal shock. The refractory panels in DuraFlex wood-burning units crack when homeowners build oversized fires or when a hidden liner leak lets moisture seep behind the panel. In Daniels Hill homes with original 1980s DuraFlex installs, we’ve seen panels that look intact from the room but are spider-webbed behind the andirons. We remove the panels, document the cracks with photos you can see, and install HeatShield refractory replacement or OEM DuraFlex panels depending on unit age and parts availability.
Our DuraFlex Fireplace Services Process
- 1
Call and schedule. A live person answers, asks what you’re seeing, and books a window. No app, no callback queue.
- 2
Arrival and protection. Our technician arrives in uniform, lays down floor protection, and listens to your description before touching anything. Russell Haines trained our team on this: “Tell me what you’re seeing, and I’ll tell you what it actually means.”
- 3
Diagnostics with documentation. We run the unit through its cycles, check gas pressure at the manifold, inspect the venting path, and run a chimney camera if the flue is involved. You get photos and a plain-English verdict - documented like an engineer, explained like a craftsman.
- 4
Parts decision and upfront quote. We identify the failed component, check OEM DuraFlex availability against quality aftermarket equivalents we trust, and quote one flat price. The number on the estimate is the number on the invoice.
- 5
Repair, test, and cleanup. We complete most DuraFlex repairs in a single visit, test-fire the unit under normal operating conditions, check CO levels at the termination, and leave the work area cleaner than we found it.
- 6
Written guarantee. Every job leaves with our 90-Day Done Right Promise in writing - Krafted right, Every time, Your home first, Standing behind it. If it’s not right, we make it right. No paperwork, no arguing.

Why Lynchburg Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve been answering the phone with a live person for over 42 years, and we plan to be in Lynchburg in thirty more. That changes how you treat a customer. Our 90-Day Done Right Promise is in writing, not a verbal shrug. Our technicians are background-checked, uniformed, and trained on DuraFlex specifics - they know the difference between a DVC and a DFT, and they carry the right parts to finish in one trip. When DuraFlex OEM is back-ordered or discontinued, we have tested relationships with HeatShield, Gelco, and other professional-grade suppliers so you’re not left heating with space heaters while you wait. Russell Haines built this company on a straightforward idea: show up when you say you will, explain what you found without dressing it up, and don’t leave until the job is right. Done right - and we stand behind it.
FAQs
No. As an independent DuraFlex service provider, we follow manufacturer-specified procedures and use OEM or equivalent professional-grade parts, which preserves warranty coverage on components still within the warranty period. We document our work with photos and parts receipts in case you ever need to file a claim. Call (540) 328-6986 if you have questions about your specific unit’s warranty status.
Common DuraFlex parts - pilot assemblies, termination caps, gaskets - arrive within 3-5 business days through our suppliers. Older series parts can take 2-3 weeks if OEM, though we often have quality aftermarket equivalents in stock that we can install same-visit. We’ll tell you before we order which route we’re taking and why.
Repair makes sense when the firebox and venting are sound and the repair cost is under roughly 40% of replacement. We replace when the unit has suffered heat exchanger failure, the liner is compromised beyond relining, or parts are obsolete and unsafe to jury-rig. Our camera inspection shows you exactly what category you’re in - no guesswork, no pressure.
Once yearly, before burning season begins. Even gas units accumulate dust on the burner, develop pilot drift, and can leak combustion gases if the venting shifts. In Lynchburg, where we see temperature swings from 20°F to 70°F across a single winter week, thermal expansion loosens vent connections over time. The $89 seasonal tune-up catches this before it becomes a problem.
Skipped maintenance leads to creosote buildup, which can ignite and cause a chimney fire, or block the flue and force carbon monoxide back into the living space. The DW series liner is especially prone to glazing because of its corrugated interior. We don’t scare-sell - we show you the camera footage and let the facts speak. If it’s clean, we say so. If it’s not, we clean it. Call (540) 328-6986 to schedule.
