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.

The chimneys in this town tell a story you won’t find in newer suburbs. Walk the streets near the Battle Green, and you’re looking at private residences built before the Revolution, many still warmed by hearths that have drawn smoke for nearly three centuries. That history is why Lexington demands a sweep who understands lime mortar, irregular flue geometry, and the preservation review process that governs work on historic properties. We’ve cleaned chimneys on Percy Road where the flue serves three original hearth openings across stacked floors, and we’ve measured hand-laid flues along Massachusetts Avenue that don’t appear on any modern sizing chart. This is not standard work, and it doesn’t get standard treatment.

Why Lexington Homeowners Choose Hearthstone Chimney Co.
Lexington residents call us because they’ve learned the difference between a technician who shows up with a brush and a vacuum, and one who arrives with a camera, a measuring tape, and the patience to explain what your chimney actually needs. Our Level-2 inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics, just documented facts.
We’ve worked on homes from the colonial clusters near Clarke Street to the mid-century ranches off Waltham Street and the newer construction around Fiske Hill. In East Lexington, where the 1950s and 1960s housing stock is showing its age, we regularly find cracked flue tiles that have gone undetected for years because no previous sweep bothered to look. In the historic districts, we know to check whether your property falls under the Lexington Historic Districts Commission before recommending any exterior modification, including cap or crown replacement.
Our background-checked, uniformed technicians carry professional-grade materials from Olympia Chimney, Famco, and Copperfield. The 90-Day Done Right Promise covers every job in writing with no arguing. If it’s not right, we come back. That’s been our standard since 1984, and it’s why homeowners in Lexington keep our number posted near the hearth.
Calls are answered by a live person, 24/7. Not a voicemail, not a callback queue. When you have smoke backing up into your living room on a February evening, you reach someone who can dispatch help.
Chimney Cleaning Services We Offer in Lexington
Chimney Cleaning & Sweep
Our standard sweep removes creosote, debris, and obstructions from the flue, followed by a Level-1 visual inspection of accessible components. For Lexington’s mature oak and maple canopy, this is essential maintenance, heavy leaf loads accelerate creosote accumulation through the heating season. Chimney Cleaning & Sweep in Lexington
Chimney Repair
We rebuild deteriorating masonry, repoint lime mortar joints with compatible materials, and address water infiltration before freeze-thaw cycles widen the damage. On colonial-era chimneys, we match existing mortar composition rather than applying modern Portland cement that traps moisture and accelerates deterioration. Chimney Repair in Lexington
Fireplace Services
Our technicians service gas and wood-burning fireplaces, including damper repair, smoke chamber parging, and firebox restoration. In Lexington’s shared-flue colonial homes, we map all connected hearth openings before any work to prevent cross-contamination between floors. Fireplace Services in Lexington
Chimney Cap & Crown Installation
A proper cap keeps rain, animals, and debris out of your flue, while a sound crown sheds water away from the masonry below. For properties within historic district boundaries, we coordinate designs that satisfy preservation review while delivering modern protection. home
Chimney Liner & Rebuild
When flue tiles are cracked or the masonry is compromised, we install stainless steel liners from DuraFlex or complete partial or full rebuilds using industry-trusted materials. Every relining recommendation in Lexington is preceded by physical measurement, irregular flue geometry in colonial homes makes template sizing unreliable.

Our crews work throughout Lexington with the same travel-day scheduling, no neighborhood waits longer than another. These are the areas we know best:
- Lexington Center and the Battle Green historic district

- Pierce Road and the Clarke Street vicinity
Most jobs are completed in a single visit, scheduled at your convenience with a firm arrival window.
Why Lexington’s Climate & Housing Affect Chimney Cleaning
Lexington sits in a microclimate that punishes chimneys more severely than towns just twenty miles inland. The New England freeze-thaw cycle here is relentless, temperatures cross the 32°F threshold dozens of times each winter, and each crossing forces water trapped in masonry to expand and contract. On newer homes with Portland-cement mortar, this is manageable. On Lexington’s colonial chimneys built with lime mortar, the degradation is accelerated and often hidden until a sweep pulls back the damper and finds powdering joints or spalled brick faces.
The town’s defining landscape feature, its dense canopy of mature oaks and maples, creates a second problem. Each fall, flues accumulate leaf debris that restricts draft and creates the conditions for accelerated creosote buildup. A chimney that draws poorly burns fuel less completely, deposits more residue, and becomes increasingly hazardous through the heating season. We’ve found nests, leaf mats, and even the occasional squirrel on roofs near the Battle Green where canopy cover is heaviest.
The housing stock itself compounds these factors. The 18th-century homes near the town center present irregular interior flue geometry, hand-laid construction with non-standardized dimensions that require physical measurement before any liner recommendation. The 1950s through 1970s ranches and split-levels, meanwhile, have flue tiles now reaching sixty to seventy years of age, the typical service life, and we’re seeing increasing frequency of cracked and shifted tiles in this cohort. Neither type of home can be served well by a sweep who treats every chimney as interchangeable.

FAQs About Chimney Cleaning in Lexington
A standard chimney sweep with Level-1 inspection in Lexington typically costs between $189 and $289, depending on flue accessibility, the number of appliances served, and whether creosote buildup requires additional cleaning cycles. Level-2 camera inspections, recommended for older homes or real estate transactions, run $289 to $449. Our $89 Seasonal Tune-Up is available for qualifying systems. Call (781) 404-3793 for an exact quote, estimates are free.
The National Fire Protection Association recommends annual inspection for all chimneys, with cleaning frequency determined by use and fuel type. In Lexington, we advise annual sweeping for wood-burning systems due to the heavy debris load from the town’s mature oak and maple canopy, which accelerates creosote accumulation. Gas fireplaces should still be inspected yearly for venting integrity and obstruction, even when cleaning needs are minimal. Call (781) 404-3793 to schedule.
You need a new liner only if your existing flue is damaged, improperly sized, or missing, and we won’t recommend replacement without camera evidence you can see for yourself. In Lexington’s colonial homes, irregular flue geometry often makes standard liner sizing charts unreliable, we physically measure before any recommendation. Many aging systems can continue to function safely with proper maintenance; when replacement is necessary, we use DuraFlex stainless steel liners with professional-grade fittings. Call (781) 404-3793 for a Level-2 inspection and plain-English verdict.
Skipped maintenance leads to creosote accumulation, which restricts draft and increases chimney fire risk, and debris obstruction, which can force carbon monoxide into living spaces. In Lexington’s freeze-thaw climate, minor masonry damage worsens each winter unchecked, turning a $300 repair into a $3,000 rebuild. The mature canopy means leaf and animal intrusion is not an if but a when. We document every inspection with photos so you can see exactly what condition your chimney is in and make an informed decision about timing. Call (781) 404-3793 for a free estimate.

- Danielle Norris"The cap keeps the birds out now, which after two springs of scratching noises above the bedroom is worth every penny."
- Nisha Gupta"The fireplace had never drawn properly since we moved in. He found the damper was only opening halfway on a bent linkage and fixed it in ten minutes."
