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 Cap & Crown Across New London
A chimney cap and crown replacement in New London typically runs $450 to $1,200 for standard brick or stone chimneys, and most jobs are finished the same day we start. If you’re seeing cracked mortar at the roofline, rust stains running down the brick, or water in the firebox after a coastal storm, call (860) 390-4899 and we’ll give you an upfront number before a single tool comes off the truck.
Wendell Pike started Top Hat Chimney in 1999 and has spent nearly three decades inside chimneys across southeastern Connecticut. He knows the housing stock on Federal Street, the salt line on buildings near the water, and what a shared flue in a three-family home off Broad Street looks like after ten years of coastal moisture. You’ll get a straight answer, a real arrival window, and work backed by our 90-Day Done Right Promise in writing.
Why Top Hat Chimney Is New London’s Preferred Chimney Cap & Crown Company
New London is a different animal than inland Connecticut. The salt-laden air rolling in off Long Island Sound eats metal flashing and chimney caps twice as fast as what we see 20 miles north in Norwich or Willimantic. We account for that when we spec a new cap or crown coat. That’s not something a franchise tech from out of state is going to know walking onto a three-family off Montauk Avenue.
Our customers in New London regularly mention three things: the person who answers the phone actually knows chimney work, the crew shows up inside the window they gave, and the price on the invoice matches what was quoted. That’s not a slogan. That’s how we’ve kept work coming from the same streets for years. Ask anyone on Bank Street or the blocks around Williams Park.
We’re locally owned and owner-operated. Wendell puts his name and license number on every job we do in New London. If you need a second opinion on a competing written estimate, it’s free. If you’re over 65 or a veteran, you get 10% off every job. No fine print, no boardroom language.
Our Chimney Cap & Crown Services in New London
Cap Installation
A rusted-through cap on a New London chimney is an open invitation for rain, nesting gulls, and debris to get into your flue. We install stainless and copper caps sized to your flue’s actual diameter, not whatever is on the shelf. On a three-family near the Coast Guard Academy, we routinely set caps that have to be anchored against the same wind that comes across the Sound before a nor’easter.
Cap Replacement
If your current cap is from the old round-draft style, it was probably installed for a completely different heating system than what the building runs now. New London has hundreds of pre-1920 homes that switched from coal or wood to oil and gas without ever updating the flue cap. We swap in caps rated for your current appliances and venting configuration. $40 off any repair over $200.
Crown Repair
A chimney crown is the concrete or stone slab that caps off the top of the chimney stack. It’s not the cap itself; it’s the horizontal surface the cap sits over. In New London, persistent coastal humidity and salt mist push moisture into the crown’s surface, and the freeze-thaw cycle that follows every January cracks it open. We repair crowns with a proper crown coat that slopes water away from the flue, not toward it.
Crown Coating
Instead of full crown replacement, we often seal a New London crown with a Gelco crown coat, a flexible sealant that moves with the masonry as it heats and cools. Given how fast coastal moisture works through older mortar, we recommend crown recoating every two to three seasons in New London, even on brick that was repointed recently. The camera footage and a plain-English verdict, every time, no exceptions.

Trusted Brands We Service in New London
We install and service caps, crowns, and liners from Olympia Chimney, Famco, HeatShield, and Gelco. If you have an Olympia multi-flue cap on a New London three-family that’s rusting at the seams, we can replace it before the next coastal storm window. Parts for these brands are stocked locally, so a cap swap on a home near Fort Trumbull usually happens within a week of your call. No chasing parts from a warehouse in another state.
Common Chimney Cap & Crown Problems We See in New London Homes
- Salt-driven corrosion of metal caps and flashing. The Thames River and Long Island Sound put salt in the air year-round. Steel caps that would last 15 years in Hartford rust through in under a decade on New London’s waterfront. We see the telltale orange streaks down the brickwork on homes along Pequot Avenue every spring.
- Shared flue chases in attached multifamily buildings. The dense blocks of attached and semi-attached homes near downtown New London often share a single chimney stack between two or three units. One unit’s cracked crown lets moisture into the shared chase, and suddenly the neighbor’s bedroom wall is showing efflorescence. Liability calls from landlords around the Connecticut College rental district are steady for exactly this reason.
- Crowns cracking within two to three seasons of repointing. Even a crown that looks fine in October can be carrying hairline fractures by March. Coastal humidity seeps in, January freezes, and the cycle repeats. That’s why annual inspection in New London is a necessity, not a suggestion.
- Original unlined flues from the whaling-era housing stock. A big portion of New London’s residential blocks went up between 1880 and 1920. Those original brick flues were built for wood and coal. Today they’re venting oil and gas furnaces without proper relining. We flag those on nearly every older-block inspection along Broad and Hempstead Streets.

FAQs - Chimney Cap & Crown in New London
Sound-front air carries salt that speeds up rusting on metal caps and corrosion on flashing. In practical terms, a cap that would last 12 to 15 years inland may fail in 8 to 10 near the water, and a crown that was repointed last fall can be cracked again by spring. Annual checks are the only reliable way to catch it early. Call (860) 390-4899 and we’ll schedule a free estimate before the next freeze-thaw cycle.
Yes. Shared stacks are common in New London’s older attached housing, and we handle them regularly. A multi-flue cap set over the full stack lets each unit’s flue vent independently while keeping rain and pests out. We’ll scope the top of the stack with a camera so you can see exactly what’s shared and what’s yours. Estimates are free.
A custom multi-flue cap, built to span the full masonry width. We often quote Olympia Chimney multi-flue systems for these older New London three-families because they’re engineered for the wind and salt exposure of the waterfront. The alternative of capping each flue separately leaves gaps where water can still get in.
Yes, and we saw a clear case on Federal Street where a cracked crown on a shared stack let salt-laced moisture into the chase, showing up as efflorescence in two of the three units. We installed a custom multi-flue cap from Olympia Chimney, resealed the crown with Gelco, and lined each flue with HeatShield to isolate the units and stop cross-contamination. If you’re a landlord and you’re seeing white or brown staining on interior walls near the chimney run, call us before a tenant complains.
Every two to three seasons, on most New London homes. The combo of salt-laden coastal air and freeze-thaw cycles cracks crowns faster than inland. If your crown was last coated three winters ago, plan on getting it scoped before the next heating season. The camera doesn’t lie, and neither do we. Call (860) 390-4899 for a free estimate, no trip charge inside the county.
