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.
Fast, Reliable Chimney Repair Across Greenwich
Chimney repair in Greenwich usually runs between $350 and $2,800 depending on what’s actually wrong, and the honest answer is that you won’t know the real number until someone looks inside the flue with a camera. We’ve been doing that since 1999, and around here, the camera almost always finds something the homeowner didn’t call about. If you’re in Greenwich, CT and wondering whether that crack in the crown or the water stain near the fireplace actually matters, our Chimney Cap & Crown in Greenwich service can help - call (475) 242-5865. Wendell Pike will tell you straight whether it needs attention now or can wait until spring.
Why Top Hat Chimney Is Greenwich’s Preferred Chimney Repair Company
Greenwich is not a one-size-fits-all town, and the chimneys up in the backcountry have almost nothing in common with the ones down along the Sound except that both keep us busy. Wendell Pike started this company in 1999, and he has been in and out of chimneys in Old Greenwich, Riverside, Cos Cob, and backcountry Greenwich long enough to know which builders in which decades used which mortar. That matters when a 1926 Tudor in Riverside needs repointing and a 1980s colonial in Cos Cob just needs a crown seal. You hire a national outfit and you get a crew working off a checklist. You call us and the person who answers the phone may be the same person who shows up at your door.
Greenwich homeowners tend to ask for proof before they write a check. Good. We show camera footage of every recommendation, and no repair gets suggested without it. Our Chimney Repair team works with one rule: if we cannot show you the problem on screen, we do not ask you to pay to fix it. Every job carries the 90-Day Done Right Promise in writing. If it is not right, one call brings Wendell back at no charge. We have been around 29 years, which in this town means neighbors have watched us work on three different houses on the same street and still wave when we drive by.
Our Chimney Repair Services in Greenwich
Here is what we actually do in Greenwich, and what each job typically involves. Every one of these starts with a camera inspection so you can see what we see before any tool comes off the truck.
Mortar Repointing
Greenwich masonry from the 1890s through the 1940s was built with soft, lime-based mortar that was never meant to last a century. In backcountry estates especially, that original mortar has turned to sand in the joints. Repointing means raking out the failed mortar and packing in new material that matches both the strength and the color of the original. A typical repointing job in Greenwich runs $1,200 to $3,800 depending on how many courses have failed and how high the staging needs to go. On a three-story Gold Coast stack, expect the upper range.

Chimney Rebuilding
When freeze-thaw cycles up north of the Merritt Parkway have been working on the same brick for 100 years, the top three to six courses often spall and loosen. Sometimes you can repoint; sometimes the brick itself is gone and the only safe fix is to take the stack down to solid masonry and rebuild it. In Greenwich, a partial rebuild from the roofline up typically runs $2,500 to $6,500. We use new brick matched to the existing color and profile so the repair does not advertise itself from the street. Most Greenwich rebuilds we do are on homes where a cricket diverter was never installed, so we build that in as part of the job rather than patching the symptom.

Flashing Repair
Leaks around the chimney base are almost never a chimney problem. They are a flashing problem. The salt air in Riverside and Old Greenwich corrodes galvanized flashing faster than almost anything else in the county, and once the metal fails, water gets behind the brick and into the framing. A flashing repair in Greenwich typically runs $650 to $1,900, which includes cutting out the old metal, installing new step and counter flashing, and sealing the transition correctly. On shoreline homes we recommend stainless or copper flashing rather than galvanized, because the salt will eat galvanized again in a few winters. This is one of the most common repairs we make within sight of Long Island Sound.

Chimney Waterproofing
Water is what kills chimneys in Greenwich, not fire. We apply a vapor-permeable waterproofing treatment that keeps rain and salt spray out while still letting moisture escape from the masonry. The product we use, Gelco, soaks into the brick rather than coating it like paint. A full chimney waterproofing treatment in Greenwich runs $600 to $1,400 depending on surface area and how much prep the brick needs. If your stack is original and you intend to keep it another fifty years, this is the cheapest insurance available.

Trusted Brands We Service in Greenwich
We install and service products from Gelco, Olympia Chimney, Famco, and DuraFlex because they hold up to what this town throws at them. Salt air, freeze-thaw cycling, and multi-flue estate stacks punish equipment hard. The Famco dampers we replace in Riverside are often so corroded from decades of salt exposure that the control lever snaps off in your hand. When we put a new one in, we want it to be the last one that home needs for twenty years, so we use brands we trust enough to put our name on. If something fails anyway, the 90-Day Done Right Promise means Wendell comes back and makes it right without an invoice.
Common Chimney Repair Problems We See in Greenwich Homes
- Multiple uncoupled flues in one stack. North of the Merritt Parkway, a single exterior chimney on a backcountry estate often contains three or four separate flues sharing one masonry structure. When the clay tile between them cracks after 80 to 130 years, combustion gases from one flue can migrate into living spaces served by an entirely different flue. This configuration is rare in coastal towns like Stamford or Norwalk, which is exactly why you want a sweep who has seen it before.
- Salt-air erosion on shoreline chimneys. In Old Greenwich and Riverside, the Sound’s salt-laden air works into mortar joints and accelerates spalling at the crown. Dampers and chase covers corrode far faster than they do ten miles inland, so a chimney that looked solid last fall can have a rusted-out damper and failed flashing by spring.
- Original clay tile liners at the end of their service life. The 1890s through 1940s estates in mid-country and backcountry Greenwich were built with clay tile liners that most owners have never had inspected. When those tiles crack or offset, smoke and carbon monoxide find the path of least resistance, which is often into adjacent rooms through the shared masonry.
- Freeze-thaw crown cracking on taller stacks. Greenwich winters get cold enough to freeze water that has soaked into crown mortar, and the expansion cracks the crown open a little more each cycle. Once the crown fails, water works down into the flue and the brick, and a $900 crown repair becomes a $4,000 rebuild by the time anyone notices the interior stains.

FAQs - Chimney Repair in Greenwich
We repair a single flue inside a multi-flue stack by working from the top down and from the firebox up, using no demolition beyond what the damaged flue requires. The key is the camera inspection before any work begins: we map exactly which flue serves which fireplace or appliance, confirm the internal separation between flues, and then isolate the repair to that single flue path. In Greenwich, we commonly find that the clay tile separation between flues has already crumbled, which changes the job from a simple repair to a Chimney Liner & Rebuild in Greenwich with a DuraFlex system that restores proper separation. Call (475) 242-5865 and we will show you the camera footage before we touch a brick.
If the crack in the clay tile is only a hairline and you burn one or two fires a year, you may be able to monitor it with annual inspections rather than relining immediately. But if the tile has offset, meaning the sections no longer line up, or if the crack runs through to the masonry around it, the liner is no longer containing combustion gases and the fireplace becomes a carbon monoxide risk whether you burn rarely or often. In Old Greenwich specifically, salt-air corrosion of the metal components and chimney cap often accelerates liner deterioration, so we recommend a Chimney Cleaning & Sweep - Greenwich camera inspection before making that call. Our job is to show you the footage and tell you when it can wait. Call (475) 242-5865 for a free estimate and an honest recommendation.
Because the draft problem is almost always caused by air leaking through failed mortar joints rather than by anything inside the flue itself. Greenwich homes from the 1890s through the 1940s were built with lime mortar that degrades over decades, and once the joints open up, outside air enters the flue at every level, stealing draft and cooling the exhaust gases until they no longer rise properly. Fixing the draft means sealing those joints by repointing the stack, and that is why a “simple draft problem” in Greenwich routinely ends with a repointing recommendation that the camera evidence makes obvious. Wendell will show you exactly where the air is getting in before he recommends anything. Call (475) 242-5865.
The difference is salt. In Old Greenwich and Riverside, the salt-laden air coming off Long Island Sound corrodes standard galvanized flashing in a fraction of the time it would last inland, and once the metal starts to rust through, water gets behind the brick every time it rains. What is also different is that many older shoreline homes have chimneys that were never equipped with a cricket diverter, so water and snow pile up on the uphill side of the stack and get driven under the flashing. The proper fix is stainless or copper flashing installed correctly, plus a cricket where one is missing, not another layer of tar or sealant over the old metal. In Greenwich, expect to pay $850 to $2,400 for the job done right. Call (475) 242-5865 for an exact quote, free.
You can repair the existing flue, but you cannot continue venting a gas boiler and a wood-burning fireplace through a single 1930s clay tile flue indefinitely, because a crack in that shared flue means boiler exhaust can enter the living space or fireplace smoke can back up into the boiler. The legal and safe approach in Greenwich is to reline the flue with a properly sized stainless system and, where the appliances must remain connected, to verify separation with a camera inspection after installation. On a Riverside Tudor with salt-air corrosion, the old Famco damper probably needs replacement at the same time, and the chimney crown and nearby flashing will need Heatshield repair in Greenwich attention from the same salt exposure. Wendell and his crew handle this work regularly in Riverside; call (475) 242-5865 and we will walk through your specific configuration before recommending anything.
