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 Top Hat Chimney Is Wellesley’s Preferred Chimney Cap & Crown Company
Wendell Pike started Top Hat Chimney in 1999, and he’s been looking down Wellesley chimneys since before some of the new construction on Washington Street was even framed. That matters here because Wellesley’s housing stock isn’t like the postwar subdivisions in Natick or Framingham. The town is full of large pre-1940 Colonials, Tudors, and Georgians with two or three masonry chimneys each, and a lot of those flues were abandoned rather than properly decommissioned when the homes converted to gas heat. We find loose bricks and sheet metal sitting on top of old furnace flues all the time. It’s a moisture pathway straight into the basement, and most homeowners never know it’s there until we show them the camera footage.
The reviews we get from Wellesley customers tend to mention the same two things: we show up when we say we will, and the price we quote on the phone is the price on the invoice. No switching, no surprise add-ons. Wendell and his crew are background-checked, uniformed, and give you a real arrival window. And if something’s not right after the job, the 90-Day Done Right Promise means one call brings him back at no cost. That’s in writing, on every job.
Our Chimney Cap & Crown Services in Wellesley
Cap Installation
A missing or rusted-out cap on a Wellesley chimney is an open invitation every time the snow starts. Given the 45 to 50 inches of snowfall the town gets most winters, plus the heavy tree canopy over streets like Dover Road and Crescent Street, uncapped flues fill with debris fast. We install single-flue and multi-flue caps matched to your flue tile dimensions, using Olympia Chimney and Famco parts that we stock locally. A standard cap installation in Wellesley runs $350-$700, and we seal every edge properly against the crown.
Cap Replacement
Rust doesn’t care how much you paid for the house. A cap that’s turned into a lace doily above your Wellesley Farms chimney needs to go, and leaving it means rain, snow, and pine needles dropping straight down the flue. We’ll pull the old one, measure the tile, and set a replacement that actually fits rather than whatever was on the shelf at a big-box store. Replacement typically runs $400-$750 in this area, and we take the old cap away with us. No leaving scrap on your roof.
Crown Repair
This is the big one in Wellesley. The town’s stock of pre-WWII brick chimneys endures a hard freeze-thaw cycle every winter, and the original mortar crowns on those stacks crack along the joints year after year. Once water gets into the crown, it migrates down into the smoke chamber and firebox, and that’s when you start seeing efflorescence and spalling brick inside the home. We repair crowns with a proper sloped finish and we treat joints with a waterproof crown coating so water runs off instead of soaking in. Crown repair in Wellesley usually runs $550-$1,100 depending on flue count and condition.
Crown Coating
If the crown is still structurally sound but showing hairline cracks, a flexible crown coating is often the smartest play. It seals the surface against the freeze-thaw cycle without a full rebuild. We use Gelco and Copperfield coatings that stand up to New England winters. Coating a crown on a typical Wellesley chimney runs $350-$650, and it extends the life of the crown by years compared to leaving it open to the weather.
The multi-flue work deserves special attention here. On a Wellesley Hills Colonial with two active flues and one abandoned furnace flue, you need a multi-flue cap that spans the full crown and locks down over the unused opening. We build custom caps through Olympia Chimney when standard sizes don’t cover the crown width, and those jobs run $1,100-$1,900 depending on dimensions and material. That’s not an upsell; it’s the only correct fix for a leaking crown over three flues.

Trusted Brands We Service in Wellesley
We work with Olympia Chimney, Famco, and Copperfield products on a daily basis, and we stock the most common sizes for Wellesley’s older chimneys. That means a cap replacement typically doesn’t sit waiting on a parts order from somewhere else. Whether it’s a Famco stainless cap for a single flue or a custom Copperfield multi-flue setup for a slate-roofed colonial, we bring the right part on the first trip. If your home has an existing DuraFlex liner, we service those too, and we’ll tell you honestly whether it’s compatible with your current appliance before recommending anything.
Common Chimney Cap & Crown Problems We See in Wellesley Homes
- Frost-jacked crowns on pre-war brick stacks. Wellesley’s freeze-thaw cycle works on mortar joints every winter. By March, we routinely see crowns with cracks you could slide a dime into, and water has already started moving into the smoke chamber.
- Abandoned furnace flues capped with loose brick or sheet metal. In Wellesley Hills and Wellesley Farms especially, homes converted from coal or oil to gas decades ago, and the old furnace flue was often just covered with whatever was nearby. That gap draws moist outside air straight into the basement and attacks the masonry liner.
- Shared or adjacent flues in attached Wellesley homes. When two fireplaces share a chimney stack and one cap fails, a neighbor’s appliance exhaust can backdraft into the other fireplace flue. We see this in attached properties near the town center where stacks were built tight against each other.
- Rusted caps from years of tree debris and moisture. The mature tree canopy over most of Wellesley means leaves, pine needles, and small branches end up on chimney crowns constantly. A cap that traps that debris rots from the inside, and by the time it’s visible from the ground, it’s been failing for a while.

FAQs - Chimney Cap & Crown in Wellesley
Most of them weren’t. On homes built before 1940 that converted to gas heat, the old furnace flue was often just capped with a loose brick or a piece of sheet metal. That’s not decommissioning; it’s a temporary cover that’s been leaking moist air into your basement for years. We confirm it with a camera inspection, and if the flue isn’t venting anything, we seal it properly at the crown. Call (781) 378-5846 and we’ll put eyes on it.
Yes. When chimneys are built close together or share a party wall, a missing or failed cap on one flue can let appliance exhaust drift into an adjacent fireplace flue. It’s more common in attached homes around Wellesley center than in single-family neighborhoods, but we check for it on every multi-flue inspection. If you smell oil or gas in a fireplace you haven’t used, call us the same day.
Wellesley’s housing stock skews older, heavier on brick, and the masonry was built with lime-based mortar that doesn’t handle freeze-thaw cycles well. Combined with the town’s snowfall and the fact that most of these chimneys were built before modern crown construction standards, the crowns crack sooner. A postwar house in Natick with a poured concrete crown simply has different failure points. Call (781) 378-5846 for a crown evaluation before winter.
A multi-flue cap spans the entire chimney crown and covers all flues under one hood, which is what you need when flues sit close together or when an abandoned flue needs sealing as part of the same job. Individual caps go tile by tile and make sense when the flues are spread out. On most pre-war Wellesley chimneys, a multi-flue cap is the better fix because it also sheds water away from the whole crown. We’ll show you the difference on camera before you decide.
Usually cap it. If the flue is sound and not venting any current appliance, the correct fix is a proper cap that allows a little ventilation while keeping water and animals out. Removing the entire flue is rarely necessary and often causes more damage than it prevents. In Wellesley we see these third flues on Colonials from the 1920s and 30s all the time, and the cap is almost always what’s failed. Call (781) 378-5846 and we’ll walk you through it.
