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.

What we know about Harwinton that a national outfit won’t: your chimney was likely built for open-hearth fires in a colonial farmhouse, then retrofitted with a wood stove that never got a properly sized liner. That one detail changes everything about how your flue performs and what it costs to keep it safe. We see it every season on center-chimney capes off Hill Road, along Clearview Avenue, and throughout the 06791 zip. The camera footage and a plain-English verdict, every time, no exceptions.
Why Top Hat Chimney Is Harwinton’s Preferred Chimney Repair Company
You’ve probably seen our trucks around town, or your neighbor has our magnet on their fridge. We’ve served Harwinton homeowners long enough that we run into customers at the post office and the feed store, and we’d rather keep it that way. A national chain that rotated in last spring can’t say that.
The reviews from Harwinton customers mention the same things: a real arrival window that gets honored, a price quoted before work starts, and a sweep who doesn’t invent problems to pad the invoice. Wendell puts his name on the work. His license number is published. If something’s not right within 90 days, one call brings him back to the property at no additional cost.

When you call Top Hat Chimney, a live person answers around the clock. It may well be Wendell picking up at 9 p.m. because he’s finishing paperwork. You won’t get a call center in another state, and you won’t get a voicemail box that never returns messages. You’ll get a straight answer about whether we can be out to your place on Litchfield Turnpike this week.
We schedule carefully for Harwinton because we know the drives are long and the properties are spread out. That means we show up with the right materials on the truck the first time: mortar matched to your existing brick, crown material that can handle Litchfield Hills freeze-thaw cycles, and liners sized to the actual appliance in your house. No second trips because someone guessed wrong.
Our Chimney Repair Services in Harwinton
Every repair starts with the same question: what’s actually failing, and why? In Harwinton the “why” is usually freeze-thaw damage, creosote chemistry, or an undersized liner. Here’s what we do most often for local homeowners. This falls under our broader Chimney Repair work, but the Harwinton context is specific.
Mortar Repointing
Older Harwinton brick chimneys, especially on 19th-century farmhouses, lose mortar joints to decades of freeze-thaw cycling. Water gets in, freezes, expands, and pops the mortar loose. Repointing removes the deteriorated mortar and replaces it with a mix matched to your chimney’s age and brick hardness. In Harwinton this typically runs $40 to $80 per square foot depending on access and how much joint material needs cutting out. Ignoring it invites water behind the brick, and that’s when you’re looking at real structural work.

Spalling Brick Repair
Spalled brick is brick that’s shedding its face: flaking, crumbling, or popped off entirely. On exposed chimneys along Route 118 and the rural ridges, it’s almost always water-driven. Once the face is gone, the brick absorbs more water, freezes harder, and fails faster. We cut out the damaged units and replace them with salvaged or closely matched brick, then repoint the surrounding joints. Spalling repair in Harwinton usually runs $500 to $1,400 for a typical chimney section, depending on how many units are compromised and whether we need lift access.

Chimney Waterproofing
Waterproofing is the most underrated repair we do in Harwinton. A breathable siloxane-based water repellent soaks into the masonry and keeps rain and snowmelt out while letting moisture vapor escape. This matters on fieldstone and early brick, which absorb water aggressively. We typically recommend it after any crown repair or repointing job. Expect to pay $300 to $700 for a full chimney treatment on a standard Harwinton home. It’s cheaper than the alternative, which is doing the masonry work twice.

Flashing Repair
The flashing where your chimney meets the roof line is the single most common leak point in any house, and Harwinton’s heavy snow loads don’t help. Ice pushes under the metal, pries seams open, and then spring rain finds its way in. We replace step flashing, counter flashing, or both, fabricating the metal on site to fit your roofline. Flashing repair in Harwinton typically costs $450 to $1,100 depending on chimney size, roof pitch, and whether we’re pulling shingles or doing a full re-flash.

Common Chimney Repair Problems We See in Harwinton Homes
- Glazed Stage 3 creosote in oversized colonial flues: When a modern wood stove insert is dropped into an original 18th-century flue without a correctly sized liner, the flue never gets hot enough to burn off tar and soot. The result is a hard, shiny glaze that a standard brush won’t remove. Harwinton’s farmhouse corridors, especially around Lead Mine Brook Road and Migeon Avenue, are loaded with this exact setup.
- Freeze-thaw spalling on exposed fieldstone and early brick: Repeated hard freezes and thaws through Litchfield Hills winters crack mortar joints and pop brick faces loose on exposed chimney crowns and upper sections. Water entry follows, then the damage accelerates. Homes along the higher ridgelines see this earlier and more often than lower-lying properties.
- Crown cracking and water intrusion: Old crowns built with ordinary mortar, not proper crown mix, crack within a few seasons of Harwinton weather. Once cracked, they funnel water directly into the flue, the smoke chamber, and behind the masonry. A rebuilt crown with a proper drip edge fixes the problem at its source.
- Flashing and cap failure from snow and ice: Heavy inland snowfall and ice accumulation bend and pry flashing, and damaged chimney caps let in nesting animals and debris. A spring inspection usually turns up one or both issues on homes along Litchfield Turnpike and the rural side roads.

FAQs - Chimney Repair in Harwinton
You’re almost certainly running a modern wood stove insert into the original oversized colonial flue, and that flue never reaches draft temperature. The large, cold flue space lets exhaust gases cool too quickly, depositing tar that hardens into Stage 3 glaze. Dry wood helps but doesn’t fix the physics. The solution is a properly sized liner installed into the original flue, which restores draft and keeps exhaust hot enough to prevent glazing. Call (860) 744-2656 and we’ll show you the camera footage before we recommend anything.
Yes, and here’s why: it’s not just about creosote from burning. Harwinton’s freeze-thaw cycles, heavy snow, and spring animal nesting all cause damage during the months you’re not burning. A cracked crown or damaged cap found in June is a $500 repair. The same damage found in November, after a fall of water and ice, can be a $2,000 rebuild. Once a year, burn or no burn. Chimneys break in the off-season too.
Yes, in most cases we can remove the old crown, re-form it with proper crown mix, and install a drip edge without disturbing the fieldstone below. The work typically runs $800 to $1,500 in Harwinton depending on chimney size and access. If the water has already damaged the interior flue or smoke chamber, we’ll find it on camera and show you before recommending anything more. Call (860) 744-2656 for an exact quote, estimates are free.
First-degree creosote is soft, flaky soot that brushes away easily. Third-degree creosote is hard, shiny glaze, basically tar baked solid. It forms when flue gases cool too quickly, which is exactly what happens in Harwinton’s oversized colonial flues when a wood stove insert isn’t paired with a correctly sized liner. The glaze comes back because the underlying condition, the cold, oversized flue, hasn’t been fixed. Removing the glaze is a temporary fix. Installing a liner sized to your stove solves it for good.
Twice a burning season, or roughly every 25 to 30 full burns, whichever comes first. Harwinton’s local cordwood, while excellent fuel, produces heavier creosote loads than kiln-dried or coastal wood, and rural homes here often burn daily from October through March. If you’re burning as primary heat in an older farmhouse, you’re loading more creosote per month than a weekend-only burner in a nearby town. Call (860) 744-2656 to set up a seasonal schedule, it’s cheaper than an emergency repair.
When you’re ready to have the chimney looked at by someone who knows Harwinton’s old houses, call Top Hat Chimney at (860) 744-2656. We’ll answer the phone, schedule a real arrival window, and show you what’s actually going on inside your flue before any repair starts. Free estimates, written 90-Day Done Right Promise, and the same face you’ll see in town next weekend.
