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 & Sweep in Chesapeake: What to Know First
We provide independent DuraFlex chimney cleaning and sweep services throughout Chesapeake, with most Level 1 and Level 2 inspections completed in a single visit. A standard DuraFlex sweep and inspection runs between $189 and $329 depending on creosote buildup and whether a camera inspection is needed. We do not quote low to get in the door and then add charges; the price we agree to is the price on the invoice.
This page is for Chesapeake homeowners with DuraFlex chimney liners, caps, or venting products who need annual maintenance, suspect a performance issue, or want a second opinion on work another company recommended. If the chimney’s right, you won’t hear from me until next season. That’s the point. Call (757) 590-6579 to speak with a live person now.
How DuraFlex Products Fail - and How We Fix Them
- DuraFlex SW stainless flexible liners develop creosote packing in the corrugation valleys, especially in Chesapeake’s humid shoulder seasons when incomplete combustion is common. The liner flexes fine, but the trapped creosote reduces draft and accelerates corrosion. We rotary-clean with poly or steel whips sized to the corrugation profile, then camera-verify the valleys are open.
- DuraFlex AL aluminum liners used in gas venting applications suffer from joint separation where the slip-fit connections meet, often hidden above the smoke shelf. Our Level 2 inspection catches this with camera work; we reseat with proper DuraFlex-compatible fasteners and sealant rated for the flue gas temperature, not generic HVAC tape.
- DuraFlex DVL double-wall black pipe in fireplace installations builds ash and soot at the telescoping joint near the appliance collar. The joint seizes, making annual removal for cleaning difficult or impossible without damage. We treat these joints with high-temp anti-seize during service and replace the telescoping section if galling has already occurred.
- DuraFlex relining termination caps in Chesapeake’s coastal wind exposure clog with leaf debris and creosote combination more aggressively than inland installations. The cap’s stainless mesh corrodes from the backside where creosote holds moisture. We pull the cap, inspect the mesh integrity, and replace with a proper DuraFlex-spec cap or a Gelco equivalent if the original is no longer manufactured.
- DuraFlex smooth-wall liners in oil-to-gas conversion jobs often show spalling at the bottom termination where condensate pools. The smooth wall drains poorly compared to corrugated alternatives. We install a condensate drain tee where the installation allows, or recommend a liner material change to HeatShield resurfacing if the appliance and code permit.
Our DuraFlex Chimney Cleaning & Sweep Process
- 1
Call intake. A live person answers, notes your DuraFlex product line if you know it, and schedules. We ask about appliance type, fuel, and any performance changes you’ve noticed.
- 2
Arrival and protection. Our technician lays floor and furniture protection, then performs a Level 1 visual inspection of accessible DuraFlex components from the firebox, appliance connection, and exterior termination.
- 3
Camera inspection. For DuraFlex liners, we run a high-resolution camera the full length to document creosote distribution, joint condition, and any deterioration. You see the footage on site; we explain what we’re looking at in plain terms.
- 4
Cleaning execution. We select tools matched to your DuraFlex model: rotary systems for corrugated stainless, controlled hand brushing for aluminum gas venting, specialized whips for smooth-wall profiles. OEM-spec parts or quality aftermarket equivalents from our Copperfield and Famco inventory.
- 5
Post-service testing and documentation. We verify draft, check all DuraFlex connections for security, and provide photos with a written condition report. The 90-Day Done Right Promise applies in writing before we leave.
- 6
Cleanup and scheduling. We haul away debris, leave the work area as found, and note your next recommended service date based on your burning habits and the DuraFlex product condition.

What moves the price: accessibility of your DuraFlex termination (steep roof pitch, multiple stories), the amount of creosote or soot buildup, and whether parts need ordering versus what we carry on the truck. We discuss all of this before work begins. Call (757) 590-6579 for a free estimate - the number we give is the number you pay.
Why Chesapeake Homeowners Call Hearthstone Chimney Co. for DuraFlex Work
We’ve been working on Chesapeake chimneys since 1984, including plenty of jobs in the older homes over near the Great Bridge neighborhood where those brick fireplaces get a real workout every winter. Russell Haines and our technicians know DuraFlex products from hands-on experience, not from a catalog. When a DuraFlex part is discontinued or backordered, we have working relationships with Olympia Chimney and Gelco suppliers to keep your system operational without a long wait.
Every job carries the 90-Day Done Right Promise in writing: if it’s not right, we come back. No paperwork to dig up, no argument. Our technicians are background-checked, uniformed, and arrive in marked vehicles. Most DuraFlex cleaning and inspection jobs finish in one visit. A square deal: no surprises on the bill.
FAQs
No, professional cleaning by a qualified chimney sweep does not void your DuraFlex warranty. The warranty covers manufacturing defects, not maintenance neglect. We document our service with photos and a written report, which actually supports any future warranty claim you might need to file. As an independent DuraFlex service provider, we follow manufacturer-compatible practices without cutting corners that could cause issues later. Call (757) 590-6579 if you have warranty paperwork you’d like us to review before service.
Yes, we stock common DuraFlex caps, termination components, and connection hardware on our service vehicles. For less common DuraFlex AL or discontinued DuraFlex DVL sizes, we source through our Olympia Chimney, Famco, and Copperfield distributors with typical delivery of two to five business days. We also carry HeatShield and Gelco equivalents where code allows and the application suits. We’ll be there when we say.
The camera inspection tells the story. If we find separations, corrosion holes, or deformation in your DuraFlex liner, we show you the footage and explain whether the issue is immediate, monitorable, or cosmetic. Many DuraFlex stainless liners in Chesapeake homes have decades of service left with proper cleaning. We do not recommend replacement unless the camera evidence supports it. Photos you can see, a plain-English verdict. Call (757) 590-6579 for a free second opinion on any written estimate.
Once per burning season for wood-burning systems, or per the NFPA 211 guideline of one-eighth inch of creosote buildup. Gas-fired DuraFlex systems typically need inspection every two to three years unless you notice performance changes. Chesapeake’s humid climate means creosote can hold moisture longer, so we see more accelerated corrosion in liners that go unswept. The $89 Seasonal Tune-Up is the most economical way to stay ahead of it.
Skipped maintenance leads to creosote accumulation that restricts draft, increases the risk of chimney fire, and traps moisture against the liner wall. In DuraFlex AL aluminum products, this moisture accelerates pitting corrosion that can perforate the liner. In DuraFlex stainless products, the corrosion is slower but the draft loss is real and measurable. Carbon monoxide spillage becomes a concern when the flue cannot evacuate combustion gases properly. We do not use scare tactics, but these are real hazards with real consequences. A scheduled sweep eliminates them. Call (757) 590-6579 to book - estimates are free.
