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.

Chimney liner and rebuild work in New London, CT typically runs $1,800 to $7,500 depending on whether we’re relining a single flue or rebuilding the entire stack above the roofline. Most New London jobs take one to two days once we’re on site, and the liner installation itself is often done in a single morning. Wendell Pike and his crew have been working the tight streets and old multifamily blocks of New London long enough to know that a chimney here isn’t just yours, it may be half your neighbor’s too. Call (860) 390-4899 and we’ll give you a straight answer before a single tool comes off the truck.
Key Takeaways
- New London’s salt air from Long Island Sound eats mortar joints fast, making liner and rebuild work more urgent here than inland.
- Pre-1920 multifamily homes near downtown often share flue chases between units, so a neighbor’s failing liner can vent exhaust into your apartment.
- Stainless steel liners from DuraFlex and Copperfield are the standard fix for unlined whaling-era brick flues.
- Every job is backed by the 90-Day Done Right Promise in writing, and estimates are free.
Why Top Hat Chimney Is New London’s Preferred Chimney Liner & Rebuild Company
Wendell started Top Hat Chimney in 1999, and he’s the one who answers the phone when you call, often from the truck on his way back from a job in New London. You won’t get a call center. You get Wendell, or someone on his crew who knows exactly which block you’re on. New London customers call us because the national outfits quote one price on the phone and a different one at the door. Wendell doesn’t work that way. The number you hear up front is the number on the invoice, and the 90-Day Done Right Promise means one call brings him back if anything isn’t right.
It’s the shared flue problem that sets New London apart. In the dense blocks of attached and semi-attached buildings near downtown and around Hodges Square, two or three units often vent into one chimney. That means a chimney liner issue in one apartment is a carbon monoxide question for the whole building. Wendell has been inside enough of those shared chases to tell you exactly what you’re looking at, with camera footage to prove it.
Our Chimney Liner & Rebuild Services in New London
Stainless Steel Liner
For New London’s older brick flues, a stainless steel liner is almost always the right call. We install DuraFlex and Copperfield liners sized to your appliance and your flue, and in New London’s damp coastal air, stainless beats aluminum every time. Aluminum corrodes fast when salt mist from the Sound gets into the chase. Stainless doesn’t. A typical stainless liner install in New London runs $1,800 to $3,500 for a single flue.
Liner Replacement
When an existing liner has cracked, separated, or corroded through, we pull it and put in a properly sized replacement. In New London, we see a lot of liner failures where clay tiles were never installed in the first place, or where an old aluminum liner has rotted out from coastal humidity. A liner replacement in New London usually runs $2,200 to $4,800 depending on flue height and access.
Partial Rebuild
A partial rebuild means we take down the chimney from the roofline or from a chosen point and rebuild it with new brick, crown, and flashing. On New London’s older homes, the worst damage is almost always above the roof, where salt-laden wind off Long Island Sound has been working on the mortar for a century. Partial rebuilds in New London typically run $2,500 to $6,000 depending on how many courses we’re replacing.
Liner Repair
Not every liner needs full replacement. If the damage is localized, we can sometimes patch with a HeatShield resurfacing system, but only when the underlying flue is still structurally sound. Wendell will tell you plainly when a repair will hold and when it won’t. A liner repair in New London runs $900 to $2,200 when it’s a legitimate option.

Common Chimney Liner & Rebuild Problems We See in New London Homes
- Shared flue chases in attached multifamily blocks: Near downtown New London and along streets like Federal Street and Blackhall Street, attached homes often share a single chimney stack. One unit’s unlined, cracked flue can push exhaust into the adjacent apartment, which is why we recommend a Level 2 camera inspection any time a neighboring unit changes appliances or reports odd smells.
- Whaling-era unlined brick flues: Many New London homes built between 1880 and 1920 retain their original unlined brick flues. These were designed for coal and never relined when converted to oil or gas. Acidic exhaust eats the interior brick, and the resulting debris settles into the smoke shelf. A stainless liner solves this permanently.
- Salt-air spalling and mortar failure: Air off Long Island Sound carries salt that works into brick faces and mortar joints. In New London, even a 20-year-old chimney can show spalling that would take 50 years inland. When that masonry starts to crumble near a shared flue, exhaust and moisture get pulled backward into living spaces.
- Coastal humidity and liner sweating: Persistent sea mist keeps flue walls damp year-round in New London. Stainless liners that pass through uninsulated attic spaces in tight multifamily blocks can sweat, and that moisture collects at the base of the flue. Proper insulation and correct sizing matter more here than in dry inland towns.

FAQs - Chimney Liner & Rebuild in New London
Salt air from the Sound accelerates mortar joint spalling, metal flashing corrosion, and brick face deterioration far more aggressively in New London than in inland Connecticut towns 20 miles north. Even a recently repointed chimney can develop moisture infiltration within two to three seasons. This means liners in New London are exposed to more moisture than inland, so stainless steel is the right material, and annual inspection is non-negotiable. Call (860) 390-4899 for an exact quote, estimates are free.
Yes, and it happens in New London more than people realize because so many pre-1920 buildings share flue chases between units. If your attached neighbor connects an appliance to a shared flue without proper sizing or relining, exhaust can back up into your apartment. This is why we recommend a camera inspection any time a neighboring unit changes appliances. Wendell’s crew found two oil burners venting into a single unlined 1890s brick flue on Federal Street with clearances down to two inches from wood joists. We installed a 5.5-inch DuraFlex liner through both appliance connectors and rebuilt the crown. If you suspect a shared flue problem, call (860) 390-4899 for a free estimate.
In New London, you should budget for repointing every 8 to 12 years instead of the 20 to 25 years common inland. Salt-laden air off Long Island Sound and year-round coastal humidity keep mortar joints damp, freeze-thaw spalling breaks them down faster, and the result is earlier rebuild work. If you’re in an older multifamily block near the Thames, annual inspection is the minimum standard. Call (860) 390-4899 and Wendell will tell you what your chimney needs now and what can wait.
A stainless steel liner is almost always the right call for an unlined 1890s brick flue, and in multifamily buildings we size it for all connected appliances with proper connector runs. In New London, we’ve used 5.5-inch and 6-inch DuraFlex liners extensively for these whaling-era stacks because they handle oil, gas, and wood exhaust without corroding in damp coastal air. The alternative, leaving the unlined brick exposed, is how cross-contamination between units happens. Call (860) 390-4899 for an exact quote, estimates are free.
Third-degree creosote, the hard, glazed kind that can’t be brushed out, builds up faster in New London rental housing because of the combination of high wood and pellet stove use in older buildings and persistently damp flue walls from coastal humidity. Damp walls make creosote adhere and harden. The dense blocks of rental property near downtown and the Connecticut College area are where we see it most, especially in units where chimneys haven’t been swept in years. If you haven’t had your flue inspected this season, call (860) 390-4899, the first-degree stuff is a brush job. Third-degree is a glaze.
The Shared Flue Problem on Federal Street
On a three-family wood-frame on Federal Street, our crew found two oil burners venting into a single unlined 1890s brick flue with a missing clay tile liner and crumbling mortar. A Level 2 inspection showed the shared chase had clearances down to 2 inches from wood joists. That’s not a chimney problem. That’s a building-wide carbon monoxide risk. We installed a 5.5-inch DuraFlex stainless steel liner through both appliance connectors, rebuilt the cracked chimney crown, and replaced the rusted copper flashing before turning the system back over to the landlord. This exact situation plays out across New London’s attached housing stock, and a camera inspection is the only way to know whether your building has it.
New London sits at the mouth of the Thames River directly on Long Island Sound, and the salt-laden air from both the estuary and open water works on chimney masonry year-round. It spalls mortar joints, corrodes flashing, and keeps flue walls damp even in August. For shared flue chases in dense multifamily blocks, that dampness means exhaust and moisture get pulled backward into adjacent apartments. A chimney liner rebuild in New London isn’t just a single-home repair, it’s a neighbor-to-neighbor safety decision. One unlined, cracked flue in a shared stack can vent furnace gases into the apartment next door.
The dense blocks of attached and semi-attached homes near downtown New London, around Hodges Square, and down toward the Coast Guard Academy, were built before modern venting codes existed. Original unlined brick flues were later adapted for oil and gas appliances without proper relining. The result is what we see on nearly every older-block inspection: cracked or absent clay tile liners, clearance failures, and cross-contamination risk between units. If you live in one of these buildings and haven’t had a camera inspection, you don’t actually know what’s inside your flue. And if your neighbor hasn’t either, you’re both guessing.
Wendell has been doing this since 1999, and the one thing he won’t do is sell you work the camera can’t justify. You’ll see the footage yourself and get a plain-English verdict. If the liner can wait, he’ll say so. If it can’t, you’ll know exactly why. Call (860) 390-4899 for a free estimate. Live person answers, around the clock, and it may well be Wendell himself picking up.
