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.
Fast, Reliable Chimney Liner & Rebuild Across Maynard
Chimney liner and rebuild work in Maynard usually runs between $2,800 and $7,500 depending on flue count, liner material, and how much masonry needs to come down. Most jobs here involve century-old brick that has cycled through coal, oil, and now wood, so the work is rarely a simple liner swap. Wendell Pike and his crew have been inside enough Maynard flues to know exactly what they’ll find before the ladder goes up. Call (781) 390-9211 and we’ll give you a straight number, not a guess.
Why Top Hat Chimney Is Maynard’s Preferred Chimney Liner & Rebuild Company
Wendell founded Top Hat Chimney in 1999 and has spent the years since working the same MetroWest streets. Ask anyone on your street.

Our Chimney Liner & Rebuild Services in Maynard
Stainless Steel Liner
Stainless steel liners are the standard fix for Maynard’s shared-flue mill-era chimneys. A typical stainless steel liner installation in Maynard runs $1,800 to $3,200 for a single flue, depending on roof access and flue height. We use DuraFlex and Olympia Chimney products because they hold up to the Assabet River valley’s freeze-thaw cycles. For a two-family home where an oil furnace and a wood stove share a stack, a stainless liner is often the only code-compliant way to separate the flues.
Flexible Liner
Flexible liners make sense when a Maynard flue has slight offsets or the original clay tile is cracked in a way that makes rigid sections difficult to feed through. These jobs typically fall between $1,900 and $3,400 in Maynard. The flexible liner snakes through the existing flue path without removing interior masonry, which matters when the chimney runs through a finished wall in one of the town’s converted two-families. We’ll show you the camera footage before and after so you can see what the liner is actually doing.
Liner Replacement
When the existing liner is crumbling, cracked, or simply absent, replacement is the fix. Liner replacement in Maynard generally costs $2,200 to $4,800 depending on whether we’re pulling out old clay tile sections or resleeving a bare brick flue. The old coal-era chimneys around Main Street and the Assabet mill district often have no liner at all, just raw brick. We’ll run a camera up first, show you the footage, and give you a plain-English verdict before any work is scheduled.
Partial Rebuild
Exposure is the killer up top. Maynard’s repeated hard freezes cause spalling and mortar joint failure faster than in flatter towns nearby, so partial rebuilds of the upper courses are a regular part of our work here. A partial rebuild in Maynard typically runs $1,500 to $3,800 for the top three to five courses, plus a new crown and wash. We match the original brick and mortar color so the upper section doesn’t look like a patch job. When the damage extends deeper than the top few courses, we’ll tell you honestly whether a full rebuild is the smarter money.
Trusted Brands We Service in Maynard
We install and service liners and rebuild components from Gelco, Olympia Chimney, and Famco. These are the brands we trust on Maynard’s older chimneys because they’re built for exactly the kind of thermal stress and shared-flue conditions we see here. We stock common parts locally, which means a liner replacement on a Maynard job doesn’t stall waiting on a shipment. If your chimney already has a HeatShield or DuraFlex system, we service those too.
Common Chimney Liner & Rebuild Problems We See in Maynard Homes
- Shared stacks with no separation. The typical Maynard two-family has a single brick chimney serving flues from both units. When the liners are missing or cracked, a neighbor’s oil furnace can backdraft into your flue. We flag this on nearly every rebuild we inspect in Maynard.
- Coal-to-oil-to-wood creosote layering. A century of fuel changes leaves dense third-degree creosote glaze that a brush can’t remove. In many Maynard homes, that glaze has to be addressed with a HeatShield resurfacing or a full liner replacement before a rebuild can even start.
- Freeze-thaw spalling on upper brick. The Assabet River valley’s hard winters cycle water into the mortar joints, freeze it, and pop the brick faces off. Upper chimney sections in Maynard need attention more often than in Sudbury or Stow, where the housing stock is newer and the exposure less severe.
- Tight roof access near the mill center. The dense lots around downtown Maynard leave little room for staging. We’ve done rebuilds where the only ladder angle was off a neighbor’s driveway. That’s not a problem for us, but it’s one of the reasons a local crew familiar with these streets beats a franchise that has never parked on Nason Street.

FAQs - Chimney Liner & Rebuild in Maynard
We run a camera up your flue and show you the footage. If the bricks are bare, the joints are open, or the old clay tiles are cracked, you need a liner before any rebuild makes sense. Rebuilding the masonry without addressing the flue interior is like painting over rot. Call (781) 390-9211 and we’ll schedule the inspection.
No. If the flues inside the shared stack are not separated by intact liners, exhaust from one side can cross into the other. That means carbon monoxide from the neighbor’s oil furnace could enter your living space. This is exactly the condition we found on a two-family home on Main Street in Maynard. We installed a DuraFlex stainless steel liner in the furnace flue and rebuilt the deteriorated crown and top three courses, which separated the flues properly. If you suspect this in your building, stop using the appliance and call us at (781) 390-9211.
The combination of century-old brick, the Assabet River valley’s repeated freeze-thaw cycles, and the dense mill-era construction means the upper courses of Maynard chimneys take more weather damage than chimneys in newer Sudbury or Stow subdivisions. Water gets into the mortar joints, freezes, and pops the brick faces. We see spalling on exposed upper sections in Maynard on a regular basis, which is why partial rebuilds are a standard part of our work here.
DuraFlex stainless steel is our usual recommendation for shared-flue Maynard two-families. It’s rigid enough to hold up under the exhaust conditions, flexible enough to handle the offsets in older flue paths, and it gives us a code-compliant separation between units. We also install Gelco and Olympia Chimney liners where the conditions call for them. We’ll explain the choice when we show you the camera footage. Exact quote: call (781) 390-9211.
A rebuild removes the masonry, but not necessarily the creosote inside the flue. If the flue itself is lined with third-degree creosote glaze, that lining has to be replaced or resurfaced with HeatShield before or during the rebuild. In Maynard, where coal gave way to oil and oil gave way to wood inserts, this layered creosote is common. We’ll identify it in the camera inspection and include it in the rebuild plan so you’re not paying for a new chimney that still has a dirty flue. Call (781) 390-9211 for a free estimate.
