We’ve worked on Lexington fireplaces for decades. The town’s housing stock splits hard: centuries-old colonials with wide, multi-flue chimneys built before clay liners existed, and mid-century houses whose single flues were sized for oil furnaces and later adapted for wood or gas. Both need different approaches. Both get ours.

Our Fireplace Services in Lexington

Wood Burning Fireplace Service

Wood-burning fireplaces in Lexington work harder than most. In the rural stretches and older neighborhoods where they’re a primary heat source, creosote loads heavy and fast. Third-degree glazing - that shiny, tar-black layer - won’t brush off with standard sweeping. It needs mechanical removal or a chemical treatment cycle before it’s safe to burn again.

On Hancock Street overlooking the Battle Green, our crew opened a 1780s center chimney serving an active wood fireplace and found the old abandoned oil flue wide open at the top, dropping cross-draft down the adjacent fireplace flue and pulling animal debris into the smoke chamber. We fitted the abandoned flue with an Olympia Chimney cap, HeatShield-sealed the pitted lime-mortar flue, replaced the rusted damper, and rebuilt the cracked firebox brick before the owner burned again. That’s the kind of layered problem Lexington’s housing stock produces - and the kind we solve.

Gas Fireplace Service

Gas fireplaces in Lexington’s 1960s and 1970s splits and ranches need annual inspection too. Pilot assemblies clog, thermocouples weaken, and venting configurations that were grandfathered in decades ago may not match current code. We service the unit, check the vent termination, and test for proper draft. If your gas insert was retrofitted into an old wood fireplace, we inspect the surrounding flue for deterioration that could let combustion gases leak into wall cavities.

Fireplace Insert Installation & Service

Inserts are popular in Lexington for good reason: they turn a drafty, inefficient open fireplace into a heat-producing appliance. But installation matters enormously. An insert shoved into a flue it doesn’t fit, with an improper liner connection, creates a fire hazard and voids the warranty. We size the insert to the fireplace opening, run the correct DuraFlex liner from top to bottom, and seal the surround so room air can’t circulate behind the unit. For Battle Green-area homes, we also verify whether the exterior alteration triggers Historic Districts Commission review.

Damper Repair & Replacement

A stuck or rusted damper costs you heat up the flue all winter. In Lexington’s older chimneys, we find original throat dampers frozen solid from decades of corrosion, or top-sealing dampers whose cables have snapped. We repair what can be repaired and replace what can’t, always with a part sized to your flue and your burning pattern. A proper damper seals tight when closed and opens fully when you need the draft.

Trusted Brands We Service in Lexington

We stock parts and materials from professional-grade brands: DuraFlex liners for insert retrofits, HeatShield cerfractory sealant for resurfacing pitted lime-mortar flues, and Olympia Chimney caps sized for Lexington’s multi-flue colonials. No builder-grade substitutes. If your repair needs a specific component, we carry it or source it fast - no waiting two weeks for a part that doesn’t quite fit.

Common Fireplace Services Problems We See in Lexington Homes

• Spalling lime mortar in pre-1820 Battle Green chimneys. Hard freeze-thaw cycling inland at Lexington’s elevation breaks down lime mortar faster than in coastal towns. Sweeping with modern wire brushes on these unlined flues chews up the soft mortar joints instead of cleaning them. We use softer tools and HeatShield resurfacing where the flue wall has deteriorated.
• Orphan oil flues left open after furnace conversion. Lexington’s oil-to-gas conversions are widespread. The abandoned oil flue stays open at the top, becoming a highway for squirrels and a source of cold cross-drafts that pull smoke backward down the adjacent fireplace flue. We cap orphan flues with screened caps and seal them properly.
• Third-degree creosote on hard-burning wood stoves. Rural Lexington properties burning wood as primary heat produce glazed creosote that a standard brush won’t touch. We identify the glazing level with a camera inspection and use rotary mechanical removal or a controlled chemical treatment cycle.
• Firebox brick cracked from thermal shock. Decades of hot fires in old fireboxes with deteriorated refractory mortar lead to cracked back walls and loosened hearth brick. We rebuild with proper refractory materials, not standard mortar that’ll fail again in two seasons.
