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 Repair in Chesapeake: What to Know First
We provide independent DuraFlex chimney repair in Chesapeake, and most jobs are completed in a single visit with no-hassle upfront pricing agreed before we start. A typical DuraFlex repair runs from $180 for localized flashing work up to $2,800 for a partial rebuild with waterproofing, and we back every job with our 90-Day Done Right Promise in writing. This page is for Chesapeake homeowners who know they’ve got a DuraFlex liner, cap, or component and need straight talk on what’s failing, what it’ll cost, and who’s qualified to fix it right. Call (757) 590-6579 anytime - a live person answers, 24 hours a day.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW 316 stainless liners in older Great Bridge homes often show seam separation at the first elbow above the smoke chamber after 15-20 years of heating cycles. The 316 alloy handles corrosion well, but the flex joints work-harden and crack in Chesapeake’s humidity swings. We cut back to sound metal and install a factory-fresh DuraFlex SW section with a proper expansion joint, not a generic clamp-together patch.
- DuraFlex 304 economy liners in rental properties and flip homes corrode from the outside in when condensation sits in uninsulated chase walls. By the time the homeowner smells smoke in the attic, the 304 wall is paper-thin. We pull a camera first, document the damage with photos you can see, and replace with 316 if the budget allows - the 304-to-316 upgrade pays for itself in this climate.
- DuraFlex Pro chimney caps on waterfront homes in South Norfolk and along the Elizabeth River lose their mesh integrity to salt-air corrosion in 8-12 years, not the 20 you’d expect inland. The stainless mesh turns to fuzz and clogs with creosote. We source genuine DuraFlex Pro replacement caps or step up to a Gelco cap with marine-grade 316 mesh if the chase geometry allows.
- DuraFlex relining jobs where the original installer skipped the top plate seal leak combustion gases into the chase cavity, staining exterior brick and rotting framing. We see this in 1970s ranch homes off Battlefield Boulevard where a handyman special “saved” $200. We pull the liner, install a proper DuraFlex top plate with silicone high-temp seal, and pressure-test before we sign off.
- DuraFlex flex-to-rigid transitions in tall two-story chimneys collapse at the coupling when the support plate was undersized or installed without a proper support bracket. The liner sags, draft fails, and the fireplace smokes into the living room. We engineer a new support system with a DuraFlex-compatible support plate and rigid riser, sized for the full weight of the assembly.
Our DuraFlex Chimney Repair Process
- 1
Call and schedule. A live person answers, asks the right questions about your DuraFlex product and symptoms, and books a Level-2 camera inspection. No deposits, no pressure.
- 2
Inspect and document. Our technician runs a camera the full length of the flue, photographs every defect, and explains what you’re seeing in plain English. You get the photos and a written verdict before any work is proposed.
- 3
Diagnose and quote. We identify whether your DuraFlex component needs OEM replacement, quality aftermarket repair, or a compatible upgrade from HeatShield or Gelco. The price on the estimate is the price on the invoice.
- 4
Repair with the right materials. We use DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, or Copperfield components - professional grade, no builder-grade substitutes. Every joint, seal, and support is checked against manufacturer spec.
- 5
Test and verify. We pressure-test or smoke-test the repair, run the camera again to confirm the fix, and clean the work area. You sign off only when you’re satisfied.
- 6
Guarantee in writing. Your 90-Day Done Right Promise is documented before we leave. If it’s not right, we come back. No paperwork, no arguing.

Why Chesapeake Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve been working chimneys in Chesapeake for over 42 years, and we’ve seen DuraFlex products since they first hit the market. Russell Haines and our crew know the difference between a DuraFlex SW and a 304 economy line without pulling the label, and we stock the parts to finish most DuraFlex repairs in one visit. If the DuraFlex component is obsolete or the geometry demands it, we carry HeatShield and Gelco alternatives that mate up properly - no cobbling, no “good enough.”
Our 90-Day Done Right Promise means if it’s not right, we make it right. In writing. No arguing. Photos you can see, a plain-English verdict, and a square deal: no surprises on the bill. If the chimney’s right, you won’t hear from me until next season. That’s the point.
FAQs
No, independent repair by a qualified chimney professional does not void your DuraFlex warranty, provided OEM parts and proper installation practices are used. We are an independent DuraFlex service provider, not affiliated with or authorized by the manufacturer, and we follow DuraFlex installation specifications precisely so your warranty stays intact. Call (757) 590-6579 if you’d like us to review your warranty terms before we start.
Most DuraFlex repairs are completed in a single visit of 3-5 hours, including inspection, repair, and testing. Full liner replacements on tall chimneys may require a second day. We tell you the timeline upfront when we quote, and we don’t leave until the work is tested and right.
We source DuraFlex, HeatShield, Gelco, and other professional-grade parts directly through our supply chain - you don’t need to hunt down components. For older DuraFlex series that are discontinued, we’ll tell you honestly and propose a compatible alternative from our multi-brand inventory.
The camera inspection decides it. Localized cracks, failed top seals, or cap damage usually justify repair. If the liner shows multiple seam failures, wall thinning over 30% of its length, or corrosion from the outside in, replacement is the safer long-term call. We show you the footage and explain both options with prices. No upsell, no alarm.
A compromised DuraFlex liner or cap lets moisture into the chase, which damages brick, framing, and interior finishes - costs multiply fast. More critically, a failed liner can leak combustion gases including carbon monoxide into living spaces, or allow chimney fires to breach the chase wall. We don’t scare-sell, but we don’t soft-pedal real hazards either. Call (757) 590-6579 for a free estimate and an honest timeline of what can wait and what shouldn’t.
