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.
DuraFlex Chimney Liner & Rebuild in Chester: What to Know First
DuraFlex chimney liner and rebuild work in Chester typically runs $1,900 to $6,800 depending on liner length, flue condition, and whether the masonry crown and top courses need rebuilding too. Most of our DuraFlex jobs are done in one or two days, and as an independent DuraFlex service provider, we give you a written price before any work starts. If you own a DuraFlex liner that’s failing, or you’re wondering whether a rebuild is actually necessary, this page is for you. Wendell Pike and our crew have pulled failed stainless liners out of Chester chimneys for over two decades now, and we’ll tell you straight if the liner is the problem or if something else is going on. Call (804) 392-9342 and we’ll walk through what you’re seeing.
Key Takeaways
- DuraFlex liners fail in specific, identifiable ways: kinked corrugations, seam corrosion at the pop-rivet joints, and pinholes from condensate eating through the thinner wall sections.
- We are an independent DuraFlex service provider. We are not the manufacturer, and we don’t pretend to be.
- Every rebuild quote includes camera footage you can watch yourself before you spend a dime.
- Our 90-Day Done Right Promise is in writing on every DuraFlex job we complete in Chester.
How DuraFlex Products Fail - and How We Fix Them
- Pinhole corrosion at the pop-rivet seam on DuraFlex 316Ti liners. The rivets hold the corrugated stainless together, but after years of acidic condensate from gas appliances, the metal right around those rivets thins first. You won’t see it from the top of the chimney. We find it with a camera, and the fix is usually a full liner replacement with the same diameter, not a patch. Patching a pinhole on a gas flue is a temporary bandage, and we won’t sell you one.
- Kinked or flattened corrugations on DuraFlex flexible liner sections. This happens most often when an original installer forced the liner through an offset or a tight smoke-shelf transition. The corrugations collapse inward, and suddenly your draft drops off a cliff. The symptom is smoke backing into the house on windy days, or a fireplace that won’t stay lit. We fix it by pulling the old section and running a properly sized liner with a smooth, unhurried pull, not by yanking it through with a truck.
- Separation at the tee-body connection on DuraFlex Pro relining kits. The tee where a liner ties into a furnace or water heater flue takes the most heat cycling. Over years, the connection can work loose, and exhaust gases start leaking into the chimney cavity instead of going up the flue. We see this regularly in older Chester homes where the original install was done before current clearances were code. The fix is a proper reconnection with the correct adapter, not a wrap of foil tape.
- Creosote glaze bonded to the interior wall of DuraFlex liner sections. Stainless liners are smoother than clay tile, but they still accumulate creosote in wood-burning applications. When a homeowner skips annual sweeps, the creosote hardens into a third-degree glaze that regular brushes won’t remove. On a DuraFlex job, we inspect first, then use the right tool for what we find. If the liner is sound, we clean it and send you the camera report. If the glaze has thinned the walls, we tell you it’s time for replacement.
- Crown failure above the liner termination on DuraFlex installations. The liner is only as good as the crown that shields it. In Chester, freeze-thaw cycles split concrete crowns every few winters. Water gets in, runs down the outside of the liner, and rusts the top plate and clamp. The liner itself may be fine, but the top assembly fails. We rebuild the crown, reset the top plate, and often save the liner entirely. That’s one of those times where a homeowner expects a big bill and we hand them a smaller one.
Our DuraFlex Chimney Liner & Rebuild Process
- 1
You call (804) 392-9342. A live person answers. It may well be Wendell. We get the basic details and set a time that works for you, with a real arrival window.
- 2
We inspect the chimney and liner. Camera goes down the flue, we check the crown, the flashing, the fireplace or appliance connection, and the attic run if there is one. You get to watch the footage with us.
- 3
We give you a plain-English verdict. If the liner is sound and the problem is the crown or the cap, we say so. If the liner is failing, we explain exactly where and show you why. If it doesn’t need doing, we’ll tell you that too.
- 4
We price the job before any work starts. One number, written down. If we can use a quality aftermarket part that matches the OEM spec and saves you money, we’ll offer it. If the OEM DuraFlex part is the right call, we use it. No surprises at the end.
- 5
We do the work. Old liner out, new liner in, rebuild the crown or masonry as needed, reset the top plate and cap. We pull the liner carefully, no shortcuts, no kinks.
- 6
We test the draft, show you the final camera run, and hand you the 90-Day Done Right Promise in writing. If it’s not right, one call brings us back at no additional cost.

Why Chester Homeowners Call Top Hat Chimney for DuraFlex Work
We’ve been working chimneys in Chester since 1999, and Wendell Pike has had his name on the work that whole time. When a national outfit sends a different crew every season, the homeowner never knows who will show up. With us, the sweep who shows up is a background-checked, uniformed pro who gives you a real arrival window and calls if it slips. And when you call back with a problem, a live person answers. We know DuraFlex liners because we’ve pulled failed ones out of flues all over Chester, including plenty of older homes near Chester Village Green where the masonry tells its own story. If a DuraFlex liner isn’t the right fix for your situation, we carry HeatShield and Gelco as backup options and will tell you which one actually fits your chimney, not which one pays us more.
FAQs
A DuraFlex stainless liner replacement in Chester typically runs $1,900 to $2,800 for a single-story straight flue, and more if masonry rebuild work is needed. The exact price depends on flue height, access, and the condition of the existing chimney. Call (804) 392-9342 and we’ll give you a written estimate before any work begins.
Sometimes we can repair it, and sometimes replacement is the honest call. A loose top plate, a failed clamp, or a disconnected tee can often be fixed without pulling the liner. Pinhole corrosion along the rivet seams or collapsed corrugations usually mean full replacement. We’ll show you the camera footage and tell you which one you’re looking at.
Using a quality aftermarket part that meets the same spec generally does not void the original warranty, but some DuraFlex warranties specify OEM components for certain claims. We match the parts to the application and tell you when OEM makes sense and when an equivalent aftermarket part saves you money. If you have a warranty claim, we’ll help you document the failure properly.
Most DuraFlex liner replacements take one day. A partial rebuild adds another day. A full rebuild from the roofline up usually takes two to three days, depending on weather and masonry access. We give you a straight schedule before we start, and we call if anything slips.
You’ll usually notice one of three things: smoke backing into the house, a draft that drops off noticeably, or rust staining at the top plate or around the appliance connection. But plenty of failing liners show no symptoms at all until the camera finds pinholes or seam corrosion. Once a year, burn or no burn. Chimneys break in the off-season too. Call (804) 392-9342 and we’ll put a camera down there and show you what we see.
