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.

AfterFast, Reliable Chimney Repair Across Greenwich
Chimney repair in Greenwich typically runs $400-$1,800 for repointing and flashing work, while a full chimney rebuild on a backcountry estate can reach $8,000-$25,000 depending on flue count and brick condition. Most repairs we book in Greenwich are completed within one to two weeks, and we carry the materials crews need on the truck so we’re not running back and forth to a supply yard while your masonry sits open to the weather. Wendell Pike founded Top Hat Chimney in 1999, and he still takes the calls himself at (475) 375-2748. If you live off Round Hill Road or down near Binney Park, we know what your chimney was built with, what it’s been through, and what it needs before we even knock on the door.
Key Takeaways
- Greenwich backcountry estates often have four to eight fireplaces per property, and each flue needs its own liner sizing and evaluation. We inspect every one, not just the one you called about.
- Salt air in Old Greenwich and Riverside eats mortar faster than inland areas, which means repointing and crown work come up more often on coastal properties.
- We show you camera footage before recommending any repair. If it doesn’t need doing, we tell you that plainly and put it in writing.
- Every job is backed by the 90-Day Done Right Promise. One call brings Wendell and his crew back, no charge.
Why Top Hat Chimney Is Greenwich’s Preferred Chimney Repair Company
Greenwich homeowners tend to ask around before they hire. They want to know who their neighbor used, whether the quote held, and whether the crew cleaned up after themselves. We’ve built our reputation here the same way we built it in every town we serve: by answering the phone with a live person, showing up when we say we will, and doing the work the way we’d want it done on our own house.
Our Chimney Repair crews work on Gilded Age estates, 1920s colonials, mid-century capes, and everything in between. We know the difference between a Round Hill Road manor and a Cos Cob starter home, and we don’t take a one-size-fits-all approach to either. Some of our Greenwich customers call us because the national outfit they hired rotated a different tech through each visit and nobody remembered what was done last time. That doesn’t happen with us. Wendell has been inside more chimneys than he can count, and he still walks the big jobs himself.
When you call (475) 375-2748, a live person answers. You’ll get a real arrival window, and if it slips, we call you. You’ll get upfront pricing before any tool comes off the truck, and the number on the phone is the number on the invoice. That matters in Greenwich, where the houses are big and the chimney work can get complicated. Nobody wants a surprise on a six-flue estate repair.
Our Chimney Repair Services in Greenwich
Mortar Repointing
Mortar joints on Greenwich chimneys take a beating from freeze-thaw cycles, and in coastal neighborhoods like Old Greenwich and Riverside, salt-laden air accelerates joint erosion further. Repointing means grinding out the failed mortar and tuckpointing fresh mortar into the joints so the chimney sheds water again instead of absorbing it. On an older Greenwich home with original 1920s brick, repointing is typically the first repair we recommend, and it often prevents the need for a full rebuild down the line.
Spalling Brick Repair
Spalling is what happens when water gets into the brick itself, freezes, and blows the face off. We see it regularly on backcountry Greenwich estates where chimneys sat unmaintained for years while the owners lived in the city. A spalled brick isn’t just cosmetic; it opens the masonry to more water and weakens the structure. We replace the damaged brick to match the existing color and texture, then address the water source so it doesn’t happen again.
Chimney Waterproofing
Greenwich gets roughly 45 inches of rain and snow a year, and a lot of that lands on masonry that’s been absorbing water for decades. We apply Gelco or Olympia waterproofing sealants to the exterior masonry after repointing or rebuilding, so the chimney stays dry and the mortar doesn’t degrade year after year. Waterproofing is the step that turns a five-year repair into a thirty-year one, and we treat it as standard work on Greenwich chimneys, not an upsell.
Flashing Repair
Flashing is the metal joint where the chimney meets the roof. On Greenwich estates with steep roof pitches, dormers, and multiple roof lines around a single masonry stack, flashing fails faster and leaks more aggressively than on a simple gable roof elsewhere. We install and repair flashing with proper step and counter-flashing techniques, not caulk and hope. If water is staining your ceiling near the chimney in Riverside or Cos Cob, flashing is usually the first place we look.
Chimney Rebuilding
When a Greenwich chimney has extensive spalling, crushed mortar, or structural lean, repointing won’t save it. We rebuild from the roofline up, or from the firebox up if the damage runs deeper. Backcountry estates with original multi-flue stacks often need a partial rebuild above the roofline rather than a full teardown, which keeps the cost and the mess down. We’ll tell you honestly which one applies to your chimney.

Common Chimney Repair Problems We See in Greenwich Homes
- Multiple flues evaluated as one. Greenwich backcountry chimneys built between 1890 and 1940 often have four to eight flues in a single masonry stack, sized for coal fireplaces. A liner sized for one appliance often serves a modern gas insert in another flue with inadequate draft. We evaluate each flue on its own and size liners accordingly.
- Carriage house and guest cottage chimneys ignored for decades. Ancillary structures on Greenwich estates frequently have their own fireplaces and flues that haven’t been inspected since the property last changed hands. Spalling brick and failed flashing on a carriage house chimney can let water into the main structure without ever showing a leak inside the house.
- Third-degree creosote glaze from part-time residency. Many backcountry Greenwich estates are weekend homes, and the fireplaces get heavy use in winter and none in summer, which lets creosote layers set and harden. First-degree creosote is a brush job. Third-degree is a glaze, and it takes rotary cleaning equipment and patience.
- Salt-air mortar erosion on coastal chimneys. In Old Greenwich and Riverside, the combination of Long Island Sound salt spray and winter freeze-thaw cycles erodes mortar joints faster than anywhere inland. Homeowners who skip annual inspections end up needing full chimney rebuilds rather than simple repointing.
Pricing for Chimney Repair in Greenwich, CT
Here’s what we charge in Greenwich and why. Repointing typically runs $400-$1,200 depending on how many joints need work and how high the chimney sits. Flashing repair runs $350-$900 for a straightforward replacement, more if the roof around the chimney needs decking replaced too. A full chimney rebuild above the roofline on a Greenwich home runs $4,000-$12,000; a full teardown and rebuild from the firebox up can reach $25,000 on a multi-flue backcountry estate. Liners sized and installed for a single flue run $1,800-$4,500. You get camera footage before we recommend any of it. No line on the invoice is a suggestion. Call (475) 375-2748 for a free estimate, and remember we knock $40 off any repair over $200 and always give seniors and veterans 10% off.
Trusted Brands We Service in Greenwich
We install and service liners and waterproofing products from DuraFlex, Gelco, and Olympia Chimney. We use them because they hold up to the exact conditions Greenwich throws at a chimney: salt air, hard freezes, and decades-old masonry that needs a liner sized correctly, not just dropped in. We stock the common parts on our trucks, so the job in Cos Cob or Riverside doesn’t stall waiting on a shipment. When you call, ask Wendell which liner he’d put in his own house. He’ll tell you, and he’ll show you the receipts.
How We Handle Multi-Flue Estate Chimneys in Greenwich
Greenwich’s backcountry, north of the Merritt Parkway, is a different animal than Stamford or Darien. Those towns have their share of single-flue capes and colonials. Greenwich backcountry has Colonial, Tudor, and Georgian Revival estates built between 1890 and 1940, and many of them have four to eight fireplaces, each paired with an original masonry chimney. That means a single property can have a half-dozen flues we need to evaluate independently.
Those coal-era flues were sized for coal grates, not for modern gas inserts or wood-burning stoves. When a homeowner converts an original fireplace to gas, the old clay-tile liner often has too large a cross-section for the new appliance, which kills the draft and lets exhaust condense inside the flue. The fix is usually an appropriately sized stainless steel liner, but the diagnosis matters more than the liner. You can’t just slide a liner into a flue and call it done. We measure each flue, camera the interior, and tell you exactly what the draft is doing and what it should be doing.
Our crew worked on a 1920s Georgian Revival estate off Round Hill Road where the original four-flue masonry chimney had clay-tile liners spalled and cracked throughout. The smoke chamber was coated with third-degree creosote from decades of wood-burning use. We removed the failing liners, installed appropriately sized DuraFlex stainless steel flue liners, rebuilt the smoke chamber parging, and sealed the crown with Gelco waterproofing. Then the homeowner asked us to look at the carriage house chimney on the same parcel, which hadn’t been touched since the property changed hands in the 1990s. It needed a full Level 2 inspection plus tuckpointing of the spalling brick. That’s the thing about Greenwich estates: the work is never just the one chimney you called about.

FAQs - Chimney Repair in Greenwich
A single masonry chimney on a backcountry Greenwich estate can serve four to eight fireplaces, each with its own flue running up the same brick stack. Yes, it changes the scope of a repair. Every flue has to be evaluated on its own, because a liner sized for one appliance often serves a different appliance in an adjacent flue with inadequate draft. When we quote a repair on a multi-flue Greenwich chimney, the scope includes liner sizing, smoke chamber parging, and crown sealing for every flue, not just the one the homeowner called about. Call (475) 375-2748 for an exact quote on your property’s flue count, and remember we give a free second opinion on any written estimate.
Flashing fails faster on Greenwich estates because every roof penetration, dormer, and valley creates a point where water running down the roof changes direction and shears against the chimney. A simple colonial in Cos Cob has two roof planes meeting the chimney; a Georgian Revival with a gabled roof, two dormers, and a shed roof over the kitchen wing has four or five, and each one has its own flashing seam. More seams, more failure points, more water. We inspect the flashing at every roof-to-chimney intersection during a Level 2 inspection, and we replace failed flashing with proper step and counter-flashing rather than patching over it.
Yes, and in Greenwich it’s one of the most common missed items we find. Carriage houses, guest cottages, and pool houses on the same estate parcels frequently have their own fireplaces and flues that go uninspected for decades after the main house chimneys are serviced. The last time we looked at a carriage house off Round Hill Road with a 1930s brick chimney, the flue liner had spalled and crumbled, and the brick face was shedding like a snake. The owner had no idea. We bundle the ancillary chimney inspection with the main house inspection, and the marginal cost is small compared to the damage catching it late prevents.
Repointing is grinding out the failed mortar and packing new mortar into the joints; rebuilding is dismantling the brick and relaying it. If the mortar is gone but the bricks are still sound and the chimney hasn’t started leaning, repointing is enough. If the bricks themselves are spalled, soft, or missing faces, or if the chimney has a visible lean, you need a rebuild, at least above the roofline. In Greenwich we lean on the side of repointing when we can, because a full rebuild of a four-flue estate chimney is not a small job. But we won’t sell you repointing when the brick is beyond saving, and we’ll show you the camera footage either way.
Yes, it does. Salt-laden air blowing off Long Island Sound carries sodium chloride into the mortar joints. Salt attracts and holds water, and water that freezes in a joint expands and cracks the mortar. In Old Greenwich and Riverside, we see mortar joint erosion five to ten years earlier than in backcountry Greenwich properties at the same age, and we recommend waterproofing after repointing on coastal chimneys as standard practice. It’s not a scare tactic; it’s what the masonry looks like when we put a camera on it. Call (475) 375-2748 for a free estimate, and inside the county there’s no trip charge.
