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 Wellesley
Chimney repair in Wellesley usually runs $400 to $3,200 depending on what’s actually wrong, and the honest truth is you won’t know until somebody gets on the roof and puts a camera down the flue. We’ve worked Wellesley’s older Colonials and Tudors long enough to know that the first visible problem is rarely the one that matters. Wendell Pike founded Top Hat Chimney in 1999, and he still runs jobs himself. Call (781) 378-5846 and a live person answers, day or night.
Why Top Hat Chimney Is Wellesley’s Preferred Chimney Repair Company
Wellesley isn’t a town where you can fake it for long. Word travels down Washington Street and up into the Hills, and if you leave a job half-done, everyone hears about it by the weekend. That’s why we’ve lasted here while the national chains rotate crews in and out. Wendell and his crew work Wellesley neighborhoods every week, and we run into our customers at Roche Bros and the dump. That’s how it should be.
Every job gets a 90-Day Done Right Promise in writing. If it isn’t right, one call brings Wendell back, no invoice. The sweep who shows up is background-checked and in uniform, and the price you heard on the phone is the price on the invoice. No surprises in the driveway while the truck’s still warm. Our customers in Wellesley consistently mention that in their reviews: the number didn’t move, and the person who did the work had a name they could look up.
We answer calls from Wellesley and get someone out there without making you wait a week for a national call center to route a ticket. You’ll get a real arrival window, and if it slips, we call you before you start wondering.
Our Chimney Repair Services in Wellesley
Mortar Repointing
Wellesley’s freeze-thaw cycles work on brick joints every winter. Water gets in, freezes, expands, and pries at the mortar. On a 1920s Colonial off Central Street, that cycle repeats year after year until the joints are soft enough to scrape out with a finger. Repointing means cutting out the compromised mortar and packing in fresh, matched to the original color. In Wellesley, we price this between $1,100 and $3,900 depending on chimney height, access, and how much repointing the stack actually needs. Catching it before the bricks shift saves you a full rebuild later.
Spalling Brick Repair
Spalling is what happens when brick faces pop off from moisture damage. You’ll see flakes on the roof or on the ground near the base. In Wellesley’s older homes, one spalled brick can signal deeper trouble behind it, especially near the crown or where the flashing has let water track down the stack. We replace the damaged brick, repoint the surrounding joints, and figure out where the water came from in the first place. Spalling repair in Wellesley typically runs $700 to $2,600, more if the damage has spread through multiple courses and we’re rebuilding a section.
Chimney Waterproofing
Waterproofing is the step people skip until the third repoint. We apply a vapor-permeable sealant, usually from ChimneySaver, that keeps rain out but lets the masonry breathe. In Wellesley’s climate, where the canopy holds dampness after storms, this matters more than in drier towns. A good waterproofing job on a Wellesley stone or brick chimney usually runs $750 to $1,900, and it stretches the life of the mortar instead of fighting it.
Flashing Repair
Flashing fails quietly. The metal where the chimney meets the roofline corrodes or pulls away, and water follows the path of least resistance straight into your attic. We see this constantly on the pitched roofs around Wellesley Farms and along Cliff Road, where snow piles against the uphill side of the stack. Replacing step and counter flashing in Wellesley is normally $850 to $2,400. It’s unglamorous work, and it’s the repair that prevents rot, stains on your ceilings, and questions you don’t want to answer after a January thaw.

Trusted Brands We Service in Wellesley
We work with products from Copperfield, Olympia Chimney, and DuraFlex, and we keep the common parts on the truck because Wellesley homeowners don’t want to wait on a second trip. If you have an Olympia cap, a Copperfield damper, or a DuraFlex liner that’s underperforming, we service it the same visit. We’re also a Chimney Repair crew that does full liner installs and rebuilds, not a cleaning-only shop that won’t touch structural work. When you need parts, we bring them up the ladder with us.
Common Chimney Repair Problems We See in Wellesley Homes
- Decommissioned flues left open to the basement. Wellesley’s 1920s and 1930s homes converted from coal and oil to gas decades ago, but many of those old flues were never properly decommissioned. A loose brick or a rusted piece of sheet metal on top lets cold air and moisture pour into the basement, and then the whole house pays for it on the heating bill. In Wellesley Hills, we find this on almost every block.
- Acidic condensate eating clay tile liners. When a converted gas furnace vents through an oversized original clay tile flue, the exhaust cools too fast and condenses. The condensate is acidic, and it chews the liner from the inside. By the time you see spalling on the exterior, the inside may already need a HeatShield resurfacing or a full DuraFlex liner replacement.
- Shared stack backdrafting between attached homes. Dense Wellesley neighborhoods have attached and closely built properties that share chimney stacks. If a neighbor runs a wood fire with a compromised liner, the products of combustion can push into your flue and, in the worst cases, into your living space. The fix starts with a camera inspection that tells us which flue actually serves which appliance.
- Crown cracking from freeze-thaw cycling. Wellesley receives 45 to 50 inches of snow each winter, and the temperature swings that follow create a repeated freeze-thaw cycle. The crown, the concrete slab that tops your chimney, takes the brunt of it. Hairline cracks this spring become open fissures by next winter if they aren’t sealed, and in Wellesley’s older masonry stacks, a cracked crown is the leading cause of interior water damage.
Pricing for Chimney Repair in Wellesley, MA
In Wellesley, you should expect to pay between $400 and $3,200 for most chimney repair work. Repointing jobs land from $1,100 to $3,900, flashing replacement from $850 to $2,400, spalling brick repair between $700 and $2,600, and waterproofing from $750 to $1,900. Full chimney rebuilds in Wellesley run higher, from $6,000 to $15,000, depending on height, roof access, and whether we’re matching original brick. What moves the price? Roofline height, chimney pitch, how much scaffolding we need, the extent of hidden damage, and whether historic materials need to be sourced. Wellesley’s housing stock skews toward large, steep-roofed, architect-designed homes, so access costs more than a simple ranch in Natick. We give you a written quote before work begins, and we honor it. Call (781) 378-5846 and we’ll tell you what it costs, not what we hope you’ll pay after we’re on your roof.
And before I forget: we offer $40 off any repair over $200, a free second opinion on any written estimate from another company, no trip charge for calls inside our service county, and 10% off always for seniors and veterans. The numbers we quote are the numbers on the invoice.

FAQs - Chimney Repair in Wellesley
Yes, in most Wellesley Colonials built before 1940, an inactive furnace flue was often decommissioned with nothing more than a loose brick or sheet-metal cap, leaving an open pathway for cold air and moisture to drop straight into the basement. Wendell and his crew look for this on every Wellesley job because it’s that common. The symptoms are a basement that never warms, a persistent damp smell, and condensation on the walls near the foundation. The fix is a proper cap from Famco or a sealed cap plate with a draft vent, and in many cases the improvement in basement temperature is noticeable the same week. Call (781) 378-5846 and we’ll put a camera up there and show you exactly what’s going on.
Expect acid condensate damage. The original flue was sized for a coal or oil furnace that burned at high temperature. Your gas furnace exhausts at a much lower temperature, so the water vapor in it condenses before it leaves the flue, and that condensate is acidic enough to eat through a clay tile liner in under a decade. The result is flaking, cracked tiles, spalling on the exterior, and draft failure that can push exhaust back into the house. In Wellesley’s prewar homes, this is the single most common liner problem we see. We confirm it with a Level 2 camera inspection, then typically re-line with a properly sized DuraFlex stainless liner or resurface with HeatShield, depending on condition. The camera footage tells us and you exactly which one.
Because Wellesley’s winter conditions are harder on masonry than Natick’s. You get 45 to 50 inches of snow each year and enough freeze-thaw cycling through the season to work water into any small crack in the crown. Plus, many Wellesley Hills homes sit under dense, mature canopy that keeps the masonry damp long after a storm, holding moisture in the crown when the freeze comes. Your relatives in Natick, with newer ranches and less canopy, simply don’t get the same assault. The fix is a properly sloped concrete crown with a drip edge, not a flat patch job, and it needs a vapor-permeable waterproofing treatment every few years to hold up.
Yes, and in Wellesley’s attached and closely built homes, it happens more often than people realize. When two or more flues share one stack, a compromised liner in one flue can let combustion products cross into an adjacent flue, especially when both appliances are running. If your neighbor burns wood and your gas furnace backdrafts, the likely culprit is a crack between flues or a liner failure in the shared stack. We diagnose this with a camera inspection of each flue and a pressure test of the stack. The fix is almost always a re-line of your flue with a properly sized DuraFlex liner and, often, a conversation with the neighbor about their own liner condition.
It’s a repair issue, not a cleaning concern. Sheet metal caps rust, loosen, and let animals, water, and cold air into the flue, and in Wellesley’s older homes, that flue often opens directly into a basement or crawlspace. A good cap from Olympia Chimney or Famco seals the flue, blocks rain and snow, and stops the cold-air drop. If the flue is genuinely unused, we may recommend a proper decommissioning with a sealed cap and weep vents. If it’s still serving an appliance, the cap should include the right mesh size to keep birds out without choking the draft. Call (781) 378-5846 and we’ll tell you which cap is right for your setup and what it costs.
