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 Liner & Rebuild in Chesapeake: What to Know First
We provide independent DuraFlex chimney liner and rebuild service throughout Chesapeake, with most liner replacements and partial rebuilds completed in a single visit after our Level-2 camera inspection. A typical DuraFlex stainless liner job runs $2,800-$4,500 depending on flue height and condition, and we quote that number upfront so there are no surprises on the bill. This page is for homeowners who already have a DuraFlex liner or are considering one, and need straight answers about what’s failing, what it costs to fix, and who in Chesapeake actually knows these systems. Call us at (757) 590-6579 - a live person answers, 24 hours a day.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW304 and SW316 flexible liners: The corrugated walls on these stainless models can develop crevice corrosion at the flex points where condensation pools, especially in Chesapeake’s humid shoulder seasons when chimneys cool slowly. We cut back to sound metal and splice in matching DuraFlex sections with factory-approved couplers, never field-welding what should be a mechanical joint.
- DuraFlex Pro series with factory insulation: The refractory blanket can settle or compress over time, leaving bare spots that overheat adjacent masonry. In the older brick homes near Great Bridge, we’ve seen this accelerate spalling in the second and third flue courses. We re-insulate with OEM-compatible blanket or switch to a pour-in vermiculite mix where the flue configuration allows better coverage.
- DuraFlex telescoping starter sections: These adjustable top pieces save time on installation but the slip joints can work loose from thermal cycling, especially on tall colonial-style chimneys common in Greenbrier. We find the gap, re-seat with high-temp sealant rated to 2,000°F, and add a mechanical lock where the original friction fit isn’t holding.
- DuraFlex ovalized liners in fireplace inserts: When an ovalized liner is forced into a round flue without proper support, it flattens at the minor axis and restricts draft. We see this on insert retrofits where the original installer cheated the transition. Our fix is a formed oval-to-round adapter with proper support brackets, not another layer of flex jammed in the gap.
- DuraFlex termination caps and storm collars: The factory stainless caps hold up well, but the storm collar sealant fails predictably after seven to ten years in Chesapeake’s UV and salt-air exposure. Water tracks down the flue and rusts the top collar from the inside out. We replace with Gelco or Famco caps where the homeowner wants a different profile, or stay DuraFlex if matching the existing system matters for warranty documentation.
Our DuraFlex Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, day or night. We book a two-hour arrival window and send a confirmation text with your technician’s name.
- 2
Level-2 camera inspection. We run a chimney camera from top to bottom and from the cleanout up, documenting every flue course, every liner joint, every mortar gap. You get the photos and a plain-English verdict before any work is discussed.
- 3
Parts decision. If your DuraFlex liner is under original warranty, we source OEM sections and couplers. If warranty has lapsed, we may recommend quality aftermarket from Olympia Chimney or Copperfield when the spec matches and the savings are real. We explain the trade-off and you decide.
- 4
The repair or rebuild. Liner replacement, partial rebuild of the top courses, or full chimney rebuild - our background-checked, uniformed techs work with the materials specified, no substitutions without your okay.
- 5
Post-repair test and documentation. We run a smoke test or draft gauge check, depending on the appliance type. You get a written report with photos, the 90-Day Done Right Promise in writing, and a maintenance schedule.
- 6
Cleanup and final walkthrough. We leave the work area as we found it. Russell Haines or your lead tech reviews what was done, what to watch for, and when to call us back.

Why Chesapeake Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve been working on Chesapeake chimneys since before the city incorporated, and we’ve seen DuraFlex products go from a niche spec to the standard in most new liner installs. That history matters when you’re diagnosing a failure - we know which batch years had the tighter corrugation profile, which cap designs collected water, and how the local clay soil shifts brickwork differently than the sandier ground up in Virginia Beach.
Our 90-Day Done Right Promise means if it’s not right, we come back. In writing, no arguing. Most jobs finish in one visit because our trucks carry DuraFlex, HeatShield, and Gelco inventory - we’re not waiting on a parts run while your flue sits open. And when Russell Haines says he’ll be there, he’s there. If the chimney’s right, you won’t hear from me until next season. That’s the point.
FAQs
No - proper installation and repair by a qualified chimney professional does not void DuraFlex’s material warranty, though we document our work with photos and serial numbers in case you ever need to file a claim. As an independent DuraFlex service provider, we follow manufacturer specs precisely and keep records you can present if questions arise. Call (757) 590-6579 if you’d like us to review your warranty status before we start.
The camera inspection decides it - we look for wall thinning below 24 gauge equivalent, multiple perforations, or insulation breakdown that can’t be patched. A single hole or loose joint usually repairs; generalized corrosion or settled blanket means replacement. We show you the footage and explain which category you’re in, with no pressure either way. Call for a free inspection and we’ll give you the straight answer.
We stock common DuraFlex diameters and couplers on our trucks, and our supplier in Norfolk carries the full catalog with next-day availability on odd sizes. Most liner repairs happen same-visit; full replacements typically schedule within a week of your go-ahead. We don’t leave chimneys open and unsafe - if weather or parts delay us, we install a temporary cap and seal at no extra charge.
Fifteen years is getting long for a flexible stainless liner in Chesapeake’s climate, but it’s not automatic retirement age. We’ve seen DuraFlex SW316 liners last twenty-plus years with dry wood, proper draft, and annual sweeping; we’ve seen SW304 fail in eight years with wet wood and poor ventilation. The camera inspection tells the real story - metal thickness, crevice depth, and collar condition don’t lie about age. Schedule yours at (757) 590-6579.
Yes - we install and repair HeatShield cerfractory flue sealant systems and Gelco stainless liners, and we’ll explain honestly when one brand suits your chimney better than another. Some flues with offset bends work better with DuraFlex flexibility; others with straight runs and minor pitting are candidates for HeatShield resurfacing at lower cost. We don’t push one brand - we match the fix to the flue.
