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 Cos Cob Homeowners Choose Top Hat Chimney
Start with the obvious: the person answering your call might be Wendell himself. Not a call center. Not a dispatcher three states away. Wendell founded this company in 1999 and still puts his name and license number on every job. Ask anyone on your street. The neighborhoods around Cos Cob Harbor and down Strickland Road know him. He’s the sweep who shows up in a marked truck, wears a uniform, and hands you a phone number that rings his pocket if anything’s wrong after he leaves.
Every job carries the 90-Day Done Right Promise in writing. If it’s not done right, one call brings Wendell back. No arguments. No “well, technically.” Just a sweep who stands behind what he did. That matters when you’re dealing with a house full of pre-war brickwork and clay flue liners that haven’t been inspected in a decade.
Customers in the Mill Pond area and the old neighborhoods off Valley Road regularly point to two things in their reviews: the price quoted on the phone is the price on the invoice, and the sweep who arrives is someone they’ve seen around town. That second part is harder to fake than any review count.
We work with products from DuraFlex, HeatShield, and Olympia Chimney when repairs go beyond a cleaning. And if another company hands you a written estimate, bring it to us. We’ll give you a free second opinion, no strings attached.
Chimney Cleaning Services We Offer in Cos Cob
Here’s what we actually do, in plain English. No upsell pressure. No recommending work your chimney doesn’t need.
Chimney Cleaning & Sweep
A full cleaning removes creosote, soot, and any debris that’s settled in your flue since the last burn season. Wendell runs a camera down the flue before and after so you see exactly what changed. Your flue doesn’t care how the fire looks. It cares how it breathes.

Chimney Repair
Cracked mortar, spalled brick, a damper that won’t close: these all fall under repair. In Cos Cob, the salt air off Long Island Sound works mortar joints harder than anyone inland deals with. We’ll show you the damage on camera before we touch it.

Fireplace Services
From gas logs to wood-burning setups, we service the firebox, the damper, and everything between. If you’re not sure whether your fireplace needs a cleaning or a rebuild, start with an inspection. Wendell will tell you when the job does not need doing.

Chimney Cap & Crown
A cracked crown lets water into your brickwork, and in Cos Cob’s freeze-thaw cycle, that water becomes a wrecking crew. Caps keep rain, birds, and harbor wind debris out. We install and repair both, and we’ll show you the before and after.

Chimney Liner & Rebuild
When a clay liner cracks or a flue has deteriorated past the point of patching, we quote the honest fix. Often that’s a DuraFlex stainless liner. Sometimes it’s a partial rebuild. Never is it a surprise we spring on you after the fact.

Why Cos Cob’s Climate & Housing Affect Chimney Cleaning
Cos Cob sits directly on the tidal Mianus River harbor, and that position does something to chimneys that inland Fairfield County towns rarely see. The salt air drawn off Long Island Sound accelerates mortar spalling and clay flue-liner cracking on the neighborhood’s predominantly pre-WWII brick chimneys far faster than you’d find up in back-country Greenwich. The Sound-facing side of a chimney often shows heavy salt efflorescence and brick face loss while the inland side looks untouched. That asymmetric pattern is a Cos Cob signature, and it means repointing quotes sometimes have to come before any cleaning begins.
Most of the homes here are early-to-mid 20th century New England colonials and Cape Cods, many still running their original clay-tile-lined brick stacks. Those stacks often served multiple fireplaces and a central boiler flue at the same time. Three or more active flues per job is common in Cos Cob. A sweep who doesn’t know these houses might miss what’s hiding in the second or third flue. Wendell has been inside enough of them to know exactly where to look.
Freeze-thaw cycles crack mortar joints every winter. But when you add tidal salt to that equation, the mortar binders degrade faster, dampers corrode sooner, and brick faces begin to powder. All of that changes how often a chimney needs attention. Once a year, burn or no burn. Chimneys break in the off-season too.

FAQs About Chimney Cleaning in Cos Cob
A standard chimney sweep in Cos Cob runs $189 to $249 for a single flue, with larger multi-flue colonials typically landing between $279 and $329. The exact number depends on flue count, creosote buildup, and whether you want a camera inspection included. Call (475) 375-2748 for a specific quote; the estimate is free and the number won’t change when the truck arrives.
Once a year, burn or no burn. Cos Cob’s salt air and freeze-thaw cycles work on your mortar and liner even during the off-season, so an annual inspection catches small problems before they become expensive ones. If you burn more than two cords a season, consider a check before and after the burn season.
You should never be told you need a new liner without seeing the camera footage yourself. At Top Hat Chimney, the camera footage and a plain-English verdict come with every inspection, no exceptions. First-degree creosote is a brush job. Third-degree is a glaze; catch it early. If the liner is cracked, we’ll show you the cracks and tell you plainly whether it can wait. Call (475) 375-2748 if you want a straight read on your flue.
Creosote builds up in layers. The first degree brushes out easily. The second needs more work. Third-degree creosote becomes a hardened glaze that can fuel a chimney fire. In a Cos Cob colonial with multiple flues that haven’t been touched in years, that risk compounds. A chimney fire can crack a liner and send heat into the framing around your flue. It costs far less to sweep than to rebuild. Call (475) 375-2748 and get it checked before burn season.
Yes, and those are often the ones that need the most attention. Birds, harbor wind debris, and rainwater find their way into unused flues. We’ll scope it, clean it, and tell you what’s safe to burn and what isn’t. The inspection tells us whether to clean and light, or clean and repair first. Call (475) 375-2748 and we’ll walk you through it.

What Cos Cob Customers Say
"Creosote build up was bad enough that he showed me a jar of it. Explained the difference between the stages and why the wood I had been burning was the cause. I have burned seasoned wood ever since."
- Gordon Selkirk"We bought a house with a fireplace nobody had touched in a decade. He ran a camera up it, found a cracked liner tile, and told me plainly not to light a fire until it was fixed. He could have swept it, taken the money and said nothing."
- Marcus Elderidge"Wendell has swept our chimney every autumn for six years now. He knows the flue better than I know it and he tells me when it does not need doing, which is not something most trades will admit to."
- Eleanor Prescott
