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 Cleaning in Greenwich, CT | Top Hat Chimney
We provide independent Greenwich Chimney Cleaning & Sweep for DuraFlex liners across the town, from Old Greenwich shoreline colonials to backcountry estate stacks built before the First World War. Top Hat Chimney is not manufacturer-affiliated or authorized by DuraFlex, which means we tell you what the liner actually needs, not what a corporate program says to sell. The one thing that makes our DuraFlex work different here: on a single Greenwich estate call we routinely open three or four flues in one stack, each with its own liner and its own problems. Call (475) 242-5865 for a straight answer and a free estimate.
Why Greenwich Residents Choose Us for DuraFlex Service
Wendell Pike founded Top Hat Chimney in 1999 and has spent the better part of two decades running crews through chimneys all across Fairfield County. He learned building systems and ventilation at Palomar College before deciding soot and flue tile suited him better than a desk. These days he is known less for a sales pitch and more for telling homeowners straight out when a chimney just needs a cleaning and nothing else. If it doesn’t need doing, he’ll be the first one to tell you.
Greenwich homeowners call us because we know DuraFlex liners the way a mechanic knows a specific engine: what fails, when it fails, and what the salt air off Long Island Sound does to aluminum that never sees a problem ten miles inland. We keep genuine DuraFlex components on the truck for targeted repairs, and we carry the camera gear to show you exactly what we found. No inflated scope, no drama. Wendell and his crew show up in uniform, give you a real arrival window, and the price you hear on the phone is the number on the invoice. Every job carries our 90-Day Done Right Promise in writing. We also offer DuraFlex sales & service details for any liner system question you have.
Common DuraFlex Chimney Cleaning Problems We Solve in Greenwich
- Pinhole corrosion in aluminum liners near the Sound. DuraFlex AL liners in Old Greenwich and Riverside sit in salt-laden air that eats through the corrugated walls over time. You will not see it from the firebox. The camera finds the pinholes, and we show you the footage before anyone touches a brush.
- Kinked or crushed corrugated profiles in multi-flue stacks. Greenwich’s estate chimneys often hide three or four separate flues in one brick stack, and many DuraFlex liners were pulled through tight original clay tile that was never removed. A kinked liner drafts poorly and traps creosote. We see it on nearly every backcountry inspection.
- Condensate pooling at bottom tees. Long horizontal offsets on big estate chimneys leave stainless liners with standing condensate at the tee. That acidic moisture eats at the liner from the inside and smells like sulfur in the basement. Proper slope and drainage fix it; patching does not.
- Liner-to-appliance connection failures in Cos Cob and Old Greenwich. A single original flue often serves both a wood-burning fireplace and a converted oil or gas appliance. Wrong sizing at the connection causes draft reversal, and creosote builds where it should not. We rework the connection to the correct DuraFlex profile.
- Missing top termination on multi-flue estate stacks. Many Greenwich estate liners were installed before modern multi-flue cap systems existed. Unused flues sit open to rain and debris, and the liners inside corrode from the top down. A proper multi-flue cap stops it.
DuraFlex Service in Greenwich: What Local Conditions Mean for Your Equipment
North of the Merritt Parkway, in the backcountry estate district, a single exterior chimney stack commonly conceals three or four separate, uncoupled flues, one per story of a grand home. They share no internal separation beyond crumbling clay tile. That means a crack or offset on one flue silently channels combustion gases into adjacent living spaces that homeowners assume are served by entirely different chimneys. For a DuraFlex liner owner, this is not an abstract worry. We clean and camera-inspect every flue in the stack, not just the one attached to the fireplace you use. In a 1920s Tudor in Riverside, our tech found a DuraFlex AL liner with pinhole corrosion from years of salt air exposure. Creosote had leaked through those pinholes onto the original clay tile behind it, creating a hidden fire hazard. We removed the failed aluminum liner, cleaned the entire flue passage, and installed a new DuraFlex 316L stainless steel liner with a proper rain cap, restoring safe drafting without disturbing the historic brickwork. That is the norm here, not the exception.
DuraFlex Models & Products We Service in Greenwich
We service the full DuraFlex line you are likely to find in Greenwich chimneys, and when damage goes beyond what Chimney Repair in Greenwich can fix, we handle full relining: DuraFlex AL aluminum liner, DuraFlex 316L stainless steel liner, DuraFlex PRO pre-insulated liner, and DuraFlex Smooth Wall liner. We use genuine DuraFlex components when the liner is still serviceable and only needs targeted repair, such as top plates, rain caps, or tee caps. For deeper failures we are honest about replacement. If the corrugated profile is compromised or corroded beyond cleaning, we recommend full relining with a properly sized DuraFlex system rather than repeated patching. Wendell and his crew stock the common top plates, caps, and connectors locally, so most Greenwich service calls finish in one visit.
DuraFlex Service Pricing in Greenwich
Chimney cleaning for a DuraFlex-lined flue in Greenwich typically runs $180 to $340 depending on liner height, creosote stage, and how many flues are in the stack. A Level 2 camera inspection adds $150 to $300 and is worth every dollar on an estate chimney where three liners hide behind one brick face. Multi-flue cap replacement varies with stack size; we quote exact numbers before any work begins. What drives the cost here is flue count and liner condition, not square footage of the house. Call (475) 242-5865 for a free estimate and we will tell you exactly what the job needs, nothing more.

FAQs - DuraFlex Chimney Cleaning in Greenwich
Salt-laden air from Long Island Sound attacks aluminum liners at the exposed top section first, where the rain cap and storm collar trap moisture. In Old Greenwich and Riverside this happens far faster than even ten miles inland. The fix is usually a DuraFlex 316L stainless upgrade at the termination point with a properly sealed cap. Call (475) 242-5865 and we will camera the liner and show you what is happening.
Yes, but we have to verify the connection first. When one original flue serves both a wood fireplace and a converted oil or gas appliance, undersized or misaligned DuraFlex connections cause draft reversal and creosote buildup in the wrong places. We clean the liner, then camera it from top to bottom to confirm the tee and connector are sized correctly. Call (475) 242-5865 to schedule a Cos Cob inspection.
Improper installation where the installer pulled the corrugated liner through tight original clay tile without removing it first. Greenwich’s older multi-flue stacks leave almost no clearance, and the corrugations catch and crush on the way down. A kinked liner will never draft correctly until it is replaced. We see this constantly on backcountry estate work.
Yes. Many backcountry estate chimneys have three or four separate DuraFlex liners in one stack, installed before modern multi-flue cap systems existed. Unused flues sit open to rain and debris, corroding liners from the top down. We measure the stack, install a proper multi-flue cap that terminates every flue individually, and camera the whole thing so you can see the difference. Call (475) 242-5865 for a free multi-flue cap estimate.
The camera tells us. First-degree creosote is a brush job. Third-degree is a glaze, catch it early. But pinholes, kinks, crushed corrugations, or liner-to-appliance separation mean the liner is failing, and cleaning will not fix it. We show you the footage and say plainly whether the liner can stay or needs replacing. If it does not need doing, we will be the first ones to tell you. Call (475) 242-5865 for a Level 2 inspection.
