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.

Why Top Hat Chimney Is Greenwich’s Preferred Chimney Liner & Rebuild Company
Greenwich is a town with a lot of chimneys and not a lot of patience for phone-tag. Wendell Pike started Top Hat Chimney in 1999, and he still answers the phone himself more often than not. When a homeowner off Round Hill Road or down in Riverside calls about a liner that’s flaking inside the flue, they get a straight answer: what it likely is, what it might cost, and when we can be there. No call center, no script.
Our reputation in Greenwich was built one chimney at a time. Homeowners here talk. They compare notes at the transfer station and on the sidelines at Greenwich High. They know which tradespeople actually show up, and they know the ones who quote a number on the phone and change it at the door. We don’t play that game. The price we give you before a single tool comes off the truck is the price on the invoice, every time. Wendell puts his name and license number on the work, because he runs into you again at the hardware store on Saturday.
Live phone answer, around the clock. Background-checked, uniformed crew. A real arrival window, and if it slips, we call you. That matters when you’re driving up from Manhattan on a Thursday night and need to know whether someone can get to the house before you head back Sunday. And when the job’s done, it’s done under the 90-Day Done Right Promise, in writing. If it’s not right, one call brings us back. No chasing, no voicemail box.
Our Chimney Liner & Rebuild Services in Greenwich
Stainless Steel Liner
This is the workhorse fix for Greenwich chimneys, and it’s almost always the right call when an original clay-tile liner has cracked or shifted after 80 or 100 years of heat cycling. A DuraFlex stainless liner sized correctly for the appliance, whether it’s a gas insert in a Cos Cob cape or a wood stove in a backcountry farmhouse, gives you a flue that actually drafts and won’t leak combustion gases into the house. We see a lot of these on pre-war homes where the original terra-cotta tiles were never meant to handle a modern insert’s exhaust temperatures.

Flexible Liner
When the flue has bends and offsets, which is common in older Greenwich chimneys built around timber framing, a flexible liner snakes through without tearing out the masonry. It’s faster, less invasive, and it holds up to the salt air that chews through lesser components near the top of the stack. For a gas furnace or water heater vent, this is often the cleanest repair that doesn’t involve ripping open a wall.

Liner Replacement
If your existing liner is peeling, perforated, or was oversized for the original coal-fired flue and never resized for the gas insert that’s there now, a full replacement is usually the honest recommendation. We pull the old liner, inspect the flue with a camera, and show you the footage before we quote the replacement. Greenwich homeowners don’t like being told something’s failing without seeing it for themselves. Neither would we. Camera evidence, plain-English verdict, every time, no exceptions.

Partial Rebuild
A full chimney rebuild is rarely necessary. Most of the time, the damage is concentrated in the top three to five feet of the stack where weather and salt air do their worst work: spalled bricks, failed mortar joints, a crown that’s crumbled into gravel, a flashing seam that’s opened up. We can rebuild just that section, match the mortar and brick as closely as the original, and leave the lower stack intact. In backcountry Greenwich, where chimneys can run four or five stories from footing to cap, a targeted rebuild saves thousands versus tearing down the whole thing.

Trusted Brands We Service in Greenwich
We install and service liners from DuraFlex and HeatShield, and we keep common Greenwich-size components on the truck so we’re not making you wait a week for a part to ship. DuraFlex stainless is our default recommendation for coastal.properties because it shrugs off the salt air that turns ordinary galvanized components into rust flakes within a few winters. For smaller repairs to existing flue systems, we work with Gelco and Olympia Chimney parts when the job calls for them. Four decades in, we know which materials last on Long Island Sound and which ones don’t.
Common Chimney Liner & Rebuild Problems We See in Greenwich Homes
- Salt air corrosion at the cap and crown. In Old Greenwich and Riverside, the salt-laden breeze off the Sound works on exposed metal and mortar year-round. Stainless liners hold up, but only if the cap and crown seal is intact. Once the cap loosens or the crown cracks, the liner starts corroding from the top down.
- Multi-flue stacks sized for coal, paired with modern inserts. The big backcountry estates north of the Merritt were built when coal furnaces needed huge flues with slow-moving exhaust. A modern gas insert or wood stove pushes a much smaller, hotter, faster draft. Wrong sizing means condensation, creosote buildup, and liner damage. Nearly every call in these older Greenwich homes requires at least a liner evaluation, not just a sweep.
- Carriage houses and guest cottages that haven’t been touched in decades. We regularly find the ancillary structure chimney, sometimes never inspected since the property changed hands, hiding third-degree creosote glaze or a clay liner that’s cracked through in three places. Homeowners call about the main house and don’t even think about the pool house until we point it out.
- Flashing failures from coastal freeze-thaw cycles. Greenwich winters get cold enough to freeze water that’s seeped into a tiny flashing gap, then thaw it, then freeze it again. That cycle pries the flashing loose, and the next nor’easter drives water straight down the flue chase and into the ceiling below. We see this on brick-and-stone manors all over Cos Cob and Old Greenwich every spring.
Pricing for Chimney Liner & Rebuild in Greenwich, CT
Here’s what Greenwich homeowners should expect to pay, in real numbers. A stainless steel liner installation runs $2,800 to $7,500 depending on flue height, access, and whether we’re relining a one-story ranch in Riverside or a four-story backcountry stack that needs a lift rental. A partial rebuild of the top section, where salt air damage concentrates, typically runs $1,800 to $4,200. Full chimney rebuilds are rare, and we’ll tell you plainly when a partial fix will safely get you another decade instead. Camera inspection and photo report are included with every quote, so you can see exactly what you’re paying for. Estimates are free. Call (475) 375-2748 and ask for Wendell.

Why Greenwich’s Backcountry and Coastal Divide Changes the Work
Greenwich is two different chimney towns, and the work differs depending on which side of Route 1 you’re on. Along the Sound in Old Greenwich and Riverside, salt air is the primary enemy. It accelerates mortar erosion, pits the metal components at the crown, and means a chimney that would last 40 years inland needs tuckpointing or cap replacement far sooner. Stainless steel isn’t an upsell here, it’s the only material that survives the environment. We also check flashing and the cap seal on every coastal job, because those fail long before the brick does.
North of the Merritt, in the backcountry, the story changes. These are the Gilded Age and pre-war estates, built between 1890 and 1940, with four to eight fireplaces each and original multi-flue stacks. Those flues were built for coal-era heat output, wide and slow-drafting. Now they’re paired with gas inserts or modern wood stoves that need a smaller, correctly-sized flue. The result is condensation, draft reversal, and liner damage that wouldn’t happen in a newer single-flue home in Stamford or Darien. Proper liner sizing and evaluation is a defining part of nearly every backcountry job we do in Greenwich.
On a salt-air-weathered chimney in Old Greenwich, our crew found the stainless steel liner had corroded at the cap, letting flue gases eat into the crown. The homeowner had no idea anything was wrong until the ceiling stains showed up after a heavy spring rain. We rebuilt the top three feet of the stack, replaced the liner with a DuraFlex stainless system, and sealed the flashing before the first nor’easter hit. That job is under warranty, and we’ll inspect it every year for free as part of the annual sweep.
Our Chimney Liner & Rebuild team knows the difference between a coastal corrosion failure and a backcountry sizing failure, because we’ve been working both sides of Greenwich for 29 years. If you’re anywhere in Greenwich, from the Sound up to the state forest, one call to (475) 375-2748 gets you a straight answer.

FAQs - Chimney Liner & Rebuild in Greenwich
Salt air attacks the metal components at the top of the flue first, the cap, the liner’s upper section, and the flashing, accelerating corrosion that inland chimneys might not see for another decade or two. Stainless steel holds up; galvanized components don’t. Call (475) 375-2748 for a camera inspection and we’ll show you exactly what’s corroded and what it costs to put right.
Because the original 1890-1940 multi-flue stacks were sized for coal heat, not modern inserts or stoves. An oversized flue causes condensation and draft problems that damage liners even when the fireplace sits cold most of the year. A liner evaluation tells you whether the sizes match, and it’s included with every sweep. Call (475) 375-2748 to schedule one before the burning season.
Get it on the schedule now. We routinely find third-degree creosote glaze and cracked clay-tile liners in ancillary structures that haven’t been touched since the property last changed hands. The fix is usually a liner replacement or partial rebuild, not a full teardown. Call (475) 375-2748 and we’ll start with a camera inspection, so you see the condition before deciding anything.
In most cases, yes, only the top portion needs rebuilding. Salt air damage concentrates in the upper three to five feet, where spalling and mortar erosion are worst. We rebuild that section, match the original brick and mortar as closely as possible, and leave the lower stack intact. Call (475) 375-2748 for an estimate based on your specific chimney.
Every year, at minimum, and we recommend a camera inspection every other year for coastal exposure. The salt air in Old Greenwich and Riverside deteriorates liner caps and upper-flue metal faster than inland climates. Annual inspection catches corrosion before it becomes a leak or a combustion gas issue. Call (475) 375-2748 to book a sweep and inspection; estimates are free.
