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 in Norwich, CT | Top Hat Chimney
We’re an independent DuraFlex service provider, not a factory shop, and we’ve been cleaning and inspecting these stainless liners across Norwich since they first started showing up in Connecticut retrofits. What makes our DuraFlex work different here is simple: we know how the Yantic and Shetucket rivers shape what happens inside your flue. Call (860) 390-4899 and Wendell or one of the crew will walk you through what you’re actually dealing with.
Why Norwich Residents Choose Us for DuraFlex Service
Wendell Pike founded Top Hat Chimney in 1999, and we’ve been inside more Norwich chimneys than we can count. Most of them are old, and plenty of them now carry a DuraFlex liner. We’ve worked on the SS 316L, the Pro, the 304, and the Smooth Wall lines long enough to know how each one behaves in a damp river valley. Our DuraFlex sales & service work covers cleaning, inspection, and repair, but the part people remember is that Wendell will tell you straight if a sweep is needed or if the liner can wait. If it does not need doing, he will tell you that too.
We prefer OEM DuraFlex components when a liner needs parts. The interlocking seams and diameters are engineered to match, and we’ve seen too many generic aftermarket pieces cause fit and condensation problems inside old brick. For Norwich service area calls, we keep the common DuraFlex fittings and caps on the truck, which means a repair on the west side doesn’t turn into a waiting game.
Common DuraFlex Chimney Cleaning Problems We Solve in Norwich
- Corrosion in 304 stainless from river-valley condensation. Norwich’s humidity sits in the Thames valley through winter, and an uninsulated DuraFlex liner in a tall, cold mill-era chimney will sweat flue gases. Over a few seasons, that moisture attacks the 304 stainless and pits the interior wall. We catch this early with a camera, because by the time you smell it, the liner’s gone.
- Liner shifting from freeze-thaw brick movement. The brick around a DuraFlex liner in an older Norwich chimney doesn’t sit still. Water gets in the mortar joints, freezes, and the whole assembly shifts. A liner that wasn’t properly supported kinks or separates at the seams, and you lose draft. We see this in the winter months more than anywhere else in the state.
- Creosote caked into the corrugated profile. DuraFlex’s corrugated surface gives it flexibility, but it also holds creosote differently than a smooth clay tile. In fireplaces that see occasional use with less-than-dry wood, the deposits turn thick and sticky fast. We use brushes sized for the liner’s diameter and go slow rather than forcing a heavy buildup off the wall and risking damage.
- Warping near the firebox on converted coal fireplaces. Half of Norwich’s 19th-century fireplaces originally burned coal. When you convert one to a wood stove, the heat load jumps, and a DuraFlex liner in a confined flue can warp. The oversized dimensions of those old coal flues don’t help with draft either, so the liner runs hotter than it was designed to.
- Missing top plates and rain caps. A surprising number of DuraFlex installs in Norwich never got a proper top plate. Water runs down the outside of the liner, pools at the base, and seeps into the old brick. The liner’s fine, but the chimney around it is slowly rotting. This is a straightforward fix if you catch it before the flashing fails.
DuraFlex Service in Norwich: What Local Conditions Mean for Your Equipment
Here’s what most DuraFlex pages won’t tell you. In Taftville, many triple-decker chimneys share a single vertical chase, and we’ve seen plenty where one flue got a DuraFlex liner while the ones next to it were left bare. That’s a setup you need a real inspection to sort out. The heat from a lined flue transfers into the chase, and if the liner isn’t isolated, you can push carbon monoxide through the brick into an adjacent unit. When we’re called to clean a DuraFlex liner in a Taftville triple-decker, we check the whole chase, not just the one flue we’re sweeping. It’s the kind of thing that matters more in Norwich than in a town where every house sits on its own foundation with its own freestanding chimney.
We were called to a Victorian on Washington Street in Greeneville a while back. The homeowner said the house smelled smoky after every rain. The DuraFlex SS 316L liner inside was intact, but it had been installed without a top plate. Water was running down the outside of the liner and pooling at the base, rusting out the flashing and feeding the old brick. We replaced the flashing, added a proper rain cap, and sealed the crown. The liner’s still in service, and the smell’s gone. That’s the difference between cleaning a liner and understanding the house around it.
DuraFlex Models & Products We Service in Norwich
We work on the full DuraFlex line that shows up in Norwich homes. That includes the SS 316L, which handles wood and pellet exhaust, the Pro series for high-efficiency appliances, the 304 for standard gas and oil flues, and the Smooth Wall where draft and cleanability matter. When a part needs replacing, we order from the OEM line rather than patching with whatever the supply house has on the shelf. Interlocking seams are dimension-specific, and a liner that doesn’t fit its own components is a liner waiting to fail. We stock common DuraFlex caps, connectors, and tees locally so a Chimney Repair in Norwich doesn’t wait on a freight truck from out of state.

FAQs - DuraFlex Chimney Cleaning in Norwich
Yes. DuraFlex’s corrugated wall holds creosote differently than a smooth clay tile, and when you’re working inside an old Norwich brick chimney with a tight chase, you can’t just run a heavy wire brush through and call it done. We use brushes sized specifically to the liner’s diameter and take our time on the deposits that have baked onto the corrugated profile. Rushing it risks damaging the liner wall, and a damaged liner in a damp Norwich chimney is a problem that multiplies. That’s why our Norwich Chimney Cleaning & Sweep service takes the time to do it properly. Call (860) 390-4899 for a cleaning that treats the liner right.
It can, but not without checking the entire chase first. In Greeneville triple-deckers where multiple flues share one brick structure, a DuraFlex liner installed in only one flue leaves the adjacent flues to the mercy of the masonry around them. The heat from the lined flue can transfer through the brick, and without proper isolation, you risk carbon monoxide moving between units. We will always inspect the full chase before we will install or clean a liner in a shared Norwich chimney. Call (860) 390-4899 and we’ll come look.
Moisture, most of the time. The Thames River valley holds humidity and fog through the winter, and an uninsulated DuraFlex liner in a cold chimney condenses flue gases on the interior wall. Over several seasons that condensation corrodes the stainless from the inside out. Add in freeze-thaw movement in the old brick shifting the liner, and you have a failure that has nothing to do with poor manufacturing and everything to do with Norwich’s climate. Call us at (860) 390-4899 if you want a camera look at what’s actually happening inside your liner.
It can be, but the old coal flue dimensions matter. Many of Norwich’s 19th-century chimneys were built oversized for coal, and when you convert to gas, the flue is still too big. A DuraFlex liner solves the sizing problem, but if the appliance runs hot and the liner sits in a confined space, you can get warping over time. We’ll spec the right liner for the appliance and the existing masonry rather than just sliding in whatever fits. Call (860) 390-4899 to talk it through.
If the camera shows pitting, seam separation, or a kink in the liner wall, cleaning will not fix it. A liner with even a small breach lets corrosive gases into the old Norwich brick around it, and the brick will fail faster than the liner will. We’ll show you the footage and give you a plain-English verdict, every time, no exceptions. If it needs replacement, we will say so. If it needs a sweep, we will say that. Call (860) 390-4899 for a Level 2 inspection and see for yourself.
