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.

Why Level Two Chimney Framingham Is Lexington’s Preferred Fireplace Services Company
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and a significant share of those have been right here in Lexington. Our Fireplace Services team knows the town’s split personality: the 18th-century center-chimney colonials clustered around the Battle Green, and the postwar ranches and split-levels that fill out the rest of the ZIP code. That local knowledge matters when a technician scopes your flue and needs to know whether they’re looking at one fireplace flue or four offset passages in a single masonry mass.
Lexington homeowners leave reviews that mention the same things repeatedly: the camera footage we show them, the written price they got before anyone touched a tool, and the text alert when their technician is on the way. Our 365-Day Done Right Promise applies to every job in Lexington - if it’s not done right, we make it right, no argument. Live phone support runs 24/7, so when you smell smoke on a cold January night or your damper won’t budge before a weekend burn, you reach a person, not a voicemail.
Our Fireplace Services in Lexington

Wood Burning Fireplace Service
Wood burning fireplaces in Lexington fall into two categories with different maintenance needs. The open hearths in Battle Green colonials often connect to multi-flue center chimneys where a technician can scope the wrong passage and miss a deteriorating secondary flue. The fireplaces in 1960s ranches off Marrett Road or Bedford Street usually run through single-flue stacks with original clay tile liners that are 60-70 years old and showing freeze-thaw damage from Lexington’s colder inland nights. We inspect both with NFPA 211 Level 2 camera scans, document what we find with photos, and give you a written price before any work begins.
For rural properties around Lexington where a wood stove is primary heat, the safe sweeping interval is shorter than the generic “once a year” advice you’ll see online. Primary-heat burning loads creosote faster, and Class III glazed creosote - the hard, tarry deposit that can’t be brushed off with standard tools - builds up in a single season of heavy use. We check for it, remove it with rotary tools when needed, and tell you honestly whether your burning practice is contributing to the problem.

Gas Fireplace Service
Gas fireplaces in Lexington’s newer construction and renovated colonials need annual inspection of the burner assembly, pilot system, and venting path. We service direct-vent and vent-free units, check gas pressure and combustion air supply, and scope the vent termination for obstruction or deterioration. Sitting 11 miles inland from Boston, Lexington sees more freeze-thaw cycling than coastal towns, and we’ve found cracked vent terminations and deteriorated sealant at the thimble that coastal sweeps might not expect. Every gas service includes a written condition report and documented photo record under Haven Standard Clause 4.

Fireplace Insert Installation & Service
Fireplace inserts are the most common conversion we do in Lexington, especially in postwar ranches where the original open fireplace is inefficient and the clay tile liner is failing. An insert with a stainless steel liner system turns a drafty, 15%-efficient open hearth into a controlled-combustion heater that cuts wood consumption by half or more. We size the insert to your firebox, run a new DuraFlex or Olympia Chimney liner from the insert collar to the top of the stack, and document the installation with photos for your insurance and resale records. Materials come through Haven’s buying network, which keeps prices honest and turnaround fast for Lexington customers.

Damper Repair & Replacement
A stuck or rusted damper is one of the most common calls we get in Lexington, and it’s often the first sign of a bigger moisture problem. The damper plate and frame sit at the top of the firebox, exposed to acidic flue gases and condensation every time you burn. In Lexington’s climate, that condensation freezes in the frame, rusts the hardware, and seizes the mechanism. We can free a stuck damper, replace a rusted throat damper with a new cast-iron unit, or install a top-sealing damper that closes at the chimney crown and stops heat loss when the fireplace isn’t in use. We show you the damage on camera before quoting repair, and we never recommend replacement when repair will last.

AfterTrusted Brands We Service in Lexington
We stock and install parts from DuraFlex, HeatShield, Olympia Chimney, and Famco, sourced through Haven’s buying network specifically to keep customer prices honest. For Lexington homeowners, that means faster turnaround on liner repairs, insert installations, and damper replacements without waiting for special orders. HeatShield’s cerfractory resurfacing system lets us restore a deteriorated smoke chamber or flue liner in place rather than tearing it out, which matters in a Battle Green colonial where you don’t want a mason’s hammer inside a 250-year-old chimney mass. DuraFlex and Olympia Chimney stainless steel liners carry the warranties and listings that Lexington insurers and building officials recognize.
Common Fireplace Services Problems We See in Lexington Homes

- Multi-flue center chimneys scoped incompletely. A technician unfamiliar with colonial construction checks the primary fireplace flue and leaves, missing a deteriorating kitchen hearth flue or an informally blocked secondary passage that can leak carbon monoxide into living spaces. We inspect every flue in the stack, documented with camera footage.
- Primary-heat wood stoves swept on an annual schedule that’s too long. Rural Lexington properties burning 3-5 cords per season build creosote faster than occasional fireplace users. The safe interval is shorter, and treating a heavy-use stove like a decorative hearth risks a chimney fire. We ask about your burn volume and adjust the schedule honestly.
- 60-70 year old clay tile liners read as “staining” instead of failure. The postwar ranches around Lexington Centre and East Lexington have original clay tile flue liners that have survived decades of inland freeze-thaw cycling. Mortar joints at the crown erode, tiles spall, and cracks open. We show you the actual liner condition on camera, not a flashlight guess.
- Blocked or abandoned flues creating pressure imbalances. In center-chimney colonials, a past owner may have stuffed insulation or brick into a kitchen hearth flue without sealing it properly at the crown. Cold air drops through the partial blockage, smoke follows on startup, and the pressure differential can pull combustion gases into the house. We map the stack, identify every passage, and tell you which ones are safe, sealed, or need work.

FAQs - Fireplace Services in Lexington

Primary-heat wood stoves in Lexington typically need sweeping every 6-9 months, not annually, because burning 3-5 cords per season builds creosote faster than occasional fireplace use. The exact interval depends on wood moisture, burn temperature, and whether you’re seeing glazed deposits. We inspect and advise based on what we find, not a calendar. Call (508) 850-0489 to schedule - estimates are free.

Center-chimney colonials near the Battle Green contain two to four offset flues in one masonry mass, including kitchen hearth flues that past owners may have sealed or informally blocked. A technician unfamiliar with this construction can scope the wrong passage and leave a live carbon monoxide risk uninspected. We map every flue, run camera scans on each one, and document the condition of the entire stack. Call (508) 850-0489 for a written estimate.

No. We serve rural Lexington properties on the same flat-rate pricing structure as in-town jobs. The only difference is that primary-heat wood stoves on rural properties typically need more frequent sweeping due to heavier creosote loading, which we factor into our honest recommendation. Dispatch is coordinated from our Boston office, and you’ll get a text when your technician is en route. Call (508) 850-0489 to book.

Original clay tile flue liners from the 1950s-1970s are increasingly a problem in Lexington because 60-70 years of inland freeze-thaw cycling has eroded mortar joints at the crown and caused tiles to spall or crack. We scope the liner with a camera, show you the actual condition, and tell you whether it can be resurfaced with HeatShield, relined with stainless steel, or if it’s still sound. Nothing is recommended without photo evidence you can see yourself. Call (508) 850-0489 for an inspection.

Yes to both. We repair stuck or rusted dampers with new cast-iron throat dampers or top-sealing dampers that stop heat loss at the chimney crown. For insert conversions, we size the unit to your firebox, run a new stainless steel liner, and document the installation with photos under Haven Standard Clause 4. Written price before work starts, 365-Day Done Right Promise after. Call (508) 850-0489 for a free estimate.
