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 Liner & Rebuild Across Sudbury
When your Sudbury chimney needs a new liner or a full rebuild, the decision usually starts with a camera. We look inside the flue, show you what’s actually going on, and tell you straight whether you need work now or can safely wait. That’s how Wendell Pike has run Top Hat Chimney since 1999, and it’s why Sudbury homeowners call us when a national outfit has already quoted them a liner replacement they couldn’t verify. Call (781) 378-5846 and you’ll get a live person, a straight answer, and a written price before any work begins.
Why Top Hat Chimney Is Sudbury’s Preferred Chimney Liner & Rebuild Company
Wendell put his name and license number on the side of his first truck in 1999, and he’s been climbing onto the same Sudbury roofs ever since. The crews that arrive are background-checked, in uniform, and trained to treat your chimney the way you’d treat it yourself. When we finish a Chimney Liner & Rebuild job, you get our 90-Day Done Right Promise in writing. If something’s not right, one call brings us back at no charge. No phone tree, no regional manager.
We answer the phone around the clock, every day of the year. It might be Wendell picking up while he’s reviewing camera footage from a job on Concord Road. We also honor a few standing offers that Sudbury homeowners use regularly: $40 off any repair over $200, a free second opinion on any written estimate, no trip charge inside our service county, and 10% off always for seniors and veterans. That’s the whole deal, in the open.
Sudbury is a town where word gets around. Ask anyone on your street who’s had a liner done. Half the time, they’ll tell you Top Hat was the only outfit that showed them the camera footage instead of just pointing at a clipboard.
Our Chimney Liner & Rebuild Services in Sudbury
Stainless Steel Liner
Most Sudbury colonials built between 1965 and 1995 have original clay tile flues that are now 30 to 55 years old. When those tiles crack or the mortar joints fail, we install a stainless liner to carry exhaust safely out of the house. We use DuraFlex and Olympia Chimney liners, sized to the exact flue dimensions of your Sudbury home, not a generic kit off the shelf.
Flexible Liner
Flexible liners make sense when your Sudbury chimney has offsets or turns that a rigid liner can’t follow. Older capes and contemporary builds along Dutton Road and Pratt’s Mill Road often have flue paths that shift a few degrees mid-chase. We scope the flue first, measure the turns, and then choose a liner that fits the path without kinking or reducing draft.
Liner Replacement
When an old clay liner has failed, we pull it or run a new liner inside it, depending on what the camera shows. The Sudbury River valley’s moisture gets behind cracked tiles and accelerates mortar deterioration, so we also check the crown and flashing while we’re up there. Replacing a liner in a Sudbury colonial usually runs between $2,800 and $5,400 depending on flue height, access, and whether we’re relining one flue or two.
Partial Rebuild
Freeze-thaw cycles in Sudbury’s inland winters do real damage to the masonry above the roofline. When the top few feet of a chimney are spalled or leaning, a partial rebuild from the roofline up is often all that’s needed. We tear down to sound brick, rebuild with proper mortar and a new concrete crown, and cap it to keep animals out. A typical partial rebuild in Sudbury runs $1,800 to $4,200 depending on height and access.

Trusted Brands We Service in Sudbury
We work with Gelco, Famco, and Copperfield products regularly, and we keep common liner fittings and caps stocked for fast turnaround on Sudbury jobs. If your chimney already has a liner from one of these brands, we can service it, repair it, or replace sections without a full teardown. That’s a real advantage when you’re trying to squeeze a liner repair in before the first freeze.
Common Chimney Liner & Rebuild Problems We See in Sudbury Homes
- Freeze-thaw spalling on exposed masonry crowns: Sudbury sits about 20 miles inland, so winters run colder than towns closer to the coast. Water gets into small crown cracks, freezes and expands, and by spring you’ve got spalled brick and a flue tile loose at the top.
- River-valley efflorescence on aging crowns: The persistent ground-level moisture along the Sudbury River valley pushes water into old mortar joints. You’ll see white chalky deposits on the crown, which means water is already moving where it shouldn’t be.
- Animal intrusion through undersized caps: Conservation land buffers so many Sudbury lots that raccoons and chimney swifts have easy access to uncapped or badly capped flues. The oversized fireplace openings on 1970s and 80s builds are often fitted with aftermarket caps that leave gaps at the flue perimeter.
- Multiple flues hitting the age wall at once: Sudbury’s post-1960s colonials typically have two or more clay-tile flues. When they’re all 30 to 55 years old, failure tends to arrive together, which is why multi-flue relining and crown rebuilding is such a routine job here.

FAQs - Chimney Liner & Rebuild in Sudbury
Not always, but it’s common in Sudbury. When two flues in the same chimney were built at the same time from the same material, they often deteriorate at close to the same rate. We scope both flues with a camera and show you the footage. If one is cracked and the other is still sound, we’ll tell you to leave the good one alone. If both are failing, doing them together saves you the cost of a second scaffold setup and a second mobilization. Call (781) 378-5846 and we’ll schedule the camera inspection, free with any written estimate.
We look at the masonry, not just the flue. A liner replacement fixes the exhaust path. A rebuild fixes the structure around it. Near the Sudbury River, persistent moisture can rot mortar joints and brick from the inside, so we’ll check for spalling, leaning, and efflorescence. If the masonry above the roofline is still structurally sound, a liner replacement is usually enough. If the brick is crumbling, a partial or full rebuild is the honest answer. We show you the damage before we quote anything.
Yes, and it happens more often in Sudbury than in denser towns because of all the conservation land buffers. Raccoons tear at clay tile liners while nesting, and chimney swift colonies leave acidic droppings that eat into mortar joints. We’ve seen a raccoon nest in a flue off Old Sudbury Road where an undersized aftermarket cap had left a two-inch gap at the flue perimeter. We removed the nest, camera-scoped the liner, and sure enough, the clay tiles were cracked. A squirrel in a flue is a nuisance. A raccoon that’s been tearing at a 40-year-old clay liner can make replacement necessary.
If the clay liner is still intact and the mortar joints are tight, no. You don’t reline what isn’t broken. The issue is that Sudbury’s freeze-thaw cycles and river-valley moisture put old clay liners under stress even when you’re burning once a month. If the camera shows cracks or gaps, even occasional use sends carbon monoxide into the wall cavity instead of up and out. A stainless liner is insurance against a gas you can’t see. Call (781) 378-5846 and we’ll scope it, show you the footage, and give you a straight answer either way.
We can rebuild just the top portion, and we often do. If the damage from freeze-thaw spalling is confined to the masonry above the roofline, a partial rebuild from the roofline up fixes the problem without touching the firebox or the flue below. We only recommend a full rebuild when the damage extends into the structure behind the walls, which is less common in Sudbury unless water has been getting in for years. You’ll see the camera evidence either way.
