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 Lexington
Chimney liner replacement and partial rebuilds in Lexington typically cost between $2,200 and $6,800 depending on whether we’re working with a factory-built fireplace chase or a historic masonry stack, and most jobs are completed in a single visit with a crew that knows the difference between the two. If your Lexington home has a prefabricated fireplace from the 1970s through 1990s, the original manufacturer-specific liner and cap components may already be discontinued, making a generic swap not just risky but potentially a code violation. Call Hearthstone Chimney Co. at (781) 905-8338; a live person answers 24 hours a day, and we’ll schedule a Level 2 camera inspection that ends with photos you can see and a plain-English verdict on exactly what your chimney needs.
We’ve been serving communities like Lexington for over 42 years, and our dispatch and scheduling run out of our Boston office, which means crews are local to the Route 2 corridor and can reach the Marrett Road area, the Battle Green historic district, or the postwar neighborhoods off Woburn Street without the delays of a contractor driving in from the outer suburbs. Lexington’s housing stock doesn’t forgive guesswork. One house has a 250-year-old central chimney serving four fireplaces; the next has a 1985 factory-built unit in a framed chase. We carry the parts and the training for both.
Why Hearthstone Chimney Co. Is Lexington’s Preferred Chimney Liner & Rebuild Company
Lexington homeowners tend to stay put. The 55- to 75-year-old residents we work with on Hancock Street or along Pleasant Street have owned their homes for twenty-plus years, they’ve been burned by contractors before, and they remember it. That’s why our Chimney Liner & Rebuild team doesn’t show up to sell. We show up to document, explain, and fix what’s actually broken.
Our reputation here is built on specificity. A Level 2 inspection with our camera system produces dated photos of every flue surface, every joint, every crack in the smoke chamber. You see what we see. The verdict is in plain English, not a scare tactic. If the liner has five years left, we say so. If it’s passing combustion gases into wall cavities through hairline cracks in a 1780s lime-mortar stack, we show you the image and explain exactly why that can’t wait.
Our 90-Day Done Right Promise governs every job: Krafted right, Every time, Your home first, Standing behind it. In writing. No arguing. If it’s not right, we come back. That promise has been our standard since 1984, and it’s why Lexington customers call us back when their neighbors need a sweep.
Calls are answered by a live person, 24/7. Not voicemail, not a callback queue. Our technicians are background-checked, uniformed, and carry the professional-grade materials to complete most liner replacements and partial rebuilds in one visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice. A square deal: no surprises on the bill.
Our Chimney Liner & Rebuild Services in Lexington
Stainless Steel Liner Installation
We install Olympia Chimney and DuraFlex stainless steel liners for masonry chimneys and factory-built fireplace rebuilds throughout Lexington. In the postwar garrison colonials off Marrett Road and Woburn Street, these liners often replace thin-wall prefab assemblies that have cracked after decades of freeze-thaw cycling. Stainless steel handles the acidic condensates from modern gas appliances and the higher temperatures of wood-burning inserts better than the original materials. We size the liner to the appliance, not the other way around, and we document the installation with photos for your records.
Flexible Liner Solutions
Flexible liners solve offset flues and tight smoke chambers that rigid pipe can’t navigate. In Lexington’s older homes near the Battle Green, a central chimney may have settled slightly over 200-plus years, creating a slight jog in the flue path that would shatter a rigid liner during insertion. Our flexible DuraFlex systems conform to these offsets while maintaining the full diameter needed for proper draft. We use these selectively, not as a default, because the right liner for your chimney depends on what the camera shows.
Liner Replacement for Factory-Built Fireplaces
This is where Lexington’s housing stock gets complicated. The 1950s through 1990s garrison colonials and ranches in Lexington often contain factory-built fireplaces with manufacturer-specific liner, cap, and termination parts. Famco, older HeatShield units, and early Gelco systems are frequently discontinued. A generic stainless liner dropped into a prefab chase can void the fireplace’s UL listing, create dangerous clearances to combustible framing, and fail to seal at the termination. We source manufacturer-spec or code-compliant replacement components from Olympia Chimney and Copperfield, and when the original parts are truly gone, we perform a full liner-and-termination rebuild that restores the system to safe operation without the guesswork.
Partial Chimney Rebuild
Not every failing chimney needs to come down to the roofline. In Lexington, we regularly perform partial rebuilds: replacing a spalled crown, rebuilding the top few courses of brick, or reconstructing a damaged smoke chamber while leaving sound lower masonry in place. This is especially cost-effective for the postwar belt’s builder-grade chimneys, where the crown and top courses have taken the worst of the freeze-thaw damage but the flue below is structurally sound. We match mortar type to the existing construction, portland-cement for modern work, lime-based when we’re tying into historic masonry. Done right, a partial rebuild adds decades of service without the cost of full reconstruction.

Trusted Brands We Service in Lexington
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes. For Lexington homeowners, this means we stock the liners, caps, and termination components that match your factory-built fireplace’s original specifications, or we upgrade to an equivalent engineered system that meets current code. Because our Boston-area warehouse carries inventory for the Route 2 corridor, most Lexington jobs don’t wait on parts. We pull what we need, drive to your home, and complete the repair. Fast turnaround isn’t a slogan. It’s having the right Gelco cap on the truck when we arrive at your garrison colonial off Lowell Street.
Common Chimney Liner & Rebuild Problems We See in Lexington Homes
- Factory-built fireplace liners cracked by freeze-thaw cycling. Lexington sits 11 miles inland, which means more pronounced freeze-thaw than Boston proper. The thin-wall or prefab liners in 1970s-1990s homes crack from thermal cycling, and because the chase is enclosed, the failure hides until a Level 2 inspection finds it or water stains appear on the drywall.
- Prefab chimney caps corroded at the mounting flange. In Lexington’s postwar neighborhoods, caps on factory-built chases frequently rust where they meet the chase top. Water runs down the outside of the liner, pools in the chase framing, and mimics a liner failure. We’ve replaced $3,800 liner jobs with a $200 cap and proper flashing because we looked first.
- Discontinued manufacturer parts forcing full rebuilds. A “working” fireplace in a 1990s Lexington colonial can have a liner and cap that went out of production years ago. Generic replacements may not seal or may violate the fireplace’s listing. We verify part availability before quoting, so you’re not halfway through a repair when we discover the component no longer exists.
- Unlined central chimneys in historic homes passing gases into wall cavities. Near the Battle Green, flues sometimes run through shared central stacks with no clay tile liner, just coursed brick. Hairline cracks in deteriorated joints let combustion gases escape directly into framing. The chimney draws fine. The danger is invisible without a camera.

FAQs - Chimney Liner & Rebuild in Lexington
Yes. Factory-built fireplaces from that era use thin-wall liners and prefab caps that degrade from freeze-thaw cycling, and the enclosed chase hides damage until it’s extensive. In Lexington’s 1980s garrison colonials, we’ve found cracked liners that were still “working” in the sense that smoke went up, but combustion gases were leaking through gaps visible only on camera. Call (781) 905-8338 to schedule a Level 2 inspection; estimates are free.
Because it can void the fireplace’s UL listing, create dangerous clearances to combustible framing, and fail to seal at the termination. Factory-built systems are engineered as matched assemblies. We use manufacturer-spec or code-compliant components from Olympia Chimney and Copperfield, and when originals are discontinued, we perform a full rebuild that restores safe operation rather than improvising. Call (781) 905-8338 and we’ll verify your unit’s parts availability before quoting.
With a Level 2 camera inspection of every flue, from firebox to termination. These 18th-century central chimneys often lack clay tile liners; the flue is coursed brick with lime mortar that has checked and rechecked over centuries. We photograph every surface, document joint condition, and flag any path where combustion gases could enter wall cavities. The draft can be perfect while the structure is compromised. You’ll see the photos and get a plain-English verdict on what needs attention now versus what can be monitored. Call (781) 905-8338 to book.
A partial rebuild addresses the damaged section-typically the crown, top courses, or smoke chamber-while leaving sound lower masonry in place. A full rebuild removes the stack to the roofline or below and reconstructs. For Lexington’s postwar builder-grade chimneys, partial rebuilds are common; the crown and top courses fail first from freeze-thaw, but the flue below is often sound. Historic central chimneys near the Battle Green may need more extensive work if the lime mortar has deteriorated throughout. We never recommend full reconstruction without camera evidence showing why partial work won’t suffice. Call (781) 905-8338 for a free estimate.
Often just the liner and termination components, provided the firebox and chase framing are intact. We were called to a garrison colonial off Marrett Road where the homeowner’s factory-built fireplace had a damaged flue liner and a cracked prefab chimney cap that was letting water into the chase. Our tech pulled the old Gelco liner, found the firebox had been retrofit with a generic damper that didn’t match the original HeatShield setup, and replaced it with an Olympia Chimney stainless liner and manufacturer-spec cap. A Level 2 inspection confirmed the smoke chamber was intact and the chase framing was dry-no rebuild needed, just the right parts. Call (781) 905-8338 to find out what your unit actually needs.
