Fast, Reliable Chimney Cleaning & Sweep Across Lexington

A professional chimney cleaning and sweep in Lexington, MA typically costs between $189 and $349 for a standard Level 1 service, with Level 2 camera inspections running $279 to $425. Most appointments are completed in a single visit, and our Chimney Cleaning & Sweep team schedules Lexington homeowners within a few days of calling. If you rely on a wood stove as your primary heat source, you’ll likely need sweeping twice per season, not once, due to heavier creosote loading. Call (857) 392-4709 to book, or read on for what makes Lexington chimneys different from every other town we serve.

Call (857) 392-4709

We’ve been dispatching crews to Lexington from our Boston office for decades. We know the difference between a 1950s ranch off Woburn Street and a 1760s colonial on Hancock Street near the Battle Green, and we bring different equipment for each. That local knowledge matters because the wrong brush in the wrong flue leaves creosote behind, and the wrong liner recommendation can trigger a Historic Districts Commission review you didn’t see coming.

Our Chimney Cleaning & Sweep Services in Lexington

Level 1 Inspection

A Level 1 inspection is the baseline for any chimney that hasn’t changed and is being used as designed. In Lexington, we perform these during routine annual sweeps on 1960s and 1970s split-levels and Colonial Revivals across town, where the chimney was built for the heating appliance still in place. We check readily accessible portions of the appliance, flue, and exterior for obstructions, deposits, and structural soundness. Takes about 45 minutes. Cost runs $189 to $249.

Level 2 Inspection

Level 2 is where we bring the camera, and in Lexington, it’s essential for a specific reason. The town’s cluster of pre-1820 homes near the Battle Green has wide, multi-flue chimneys built with lime mortar and no clay tile liner, a construction type nearly absent in neighboring Burlington or Woburn. Standard brushes sized for modern flues skip the corners and mortar joints. Our camera inspection lets us see what the brush missed: second-degree creosote glazing, spalled mortar, or gaps where freeze-thaw has opened the flue wall. We document everything with photos and a plain-English verdict. Level 2 inspections in Lexington range from $279 to $425, depending on flue count and roof access.

On a Federal-period house off Hancock Street near the Battle Green, our tech found a wide unlined brick flue with second-degree creosote glazing the smoke chamber and a crumbling lime-mortar crown after a hard freeze-thaw winter. We hand-brushed the flue, removed the creosote, and installed a HeatShield liner sized to the oversized opening while choosing a cap profile that would pass Historic Districts Commission review, restoring draft to the wood-burning fireplace.

Creosote Removal

Creosote buildup is the reason most Lexington homeowners call us, especially those heating primarily with wood. First-degree creosote, fluffy and soot-like, brushes off easily. Second-degree forms shiny black flakes and requires mechanical removal. Third-degree, the tarry, hardened glaze, is a different problem entirely. It cannot be brushed out. We use rotary removal systems or, in severe cases, recommend a chemical treatment followed by a second visit. For wood-stove-primary homes in Lexington, we often find second-degree buildup by mid-season. A full creosote removal runs $249 to $389, depending on severity and flue configuration.

Soot Removal

Soot accumulation is less hazardous than creosote but still restricts draft and can harbor acidic moisture. In Lexington’s 1950s to 1970s housing stock, we see heavy soot in chimneys that were originally sized for oil furnaces and later converted to gas, leaving an oversized flue that never achieves proper draft temperature. The abandoned oil flue, still open at the top, collects soot and becomes an animal entry point. We remove soot with HEPA-contained vacuum systems and check for proper flue sizing before we leave. Standard soot removal as part of a sweep: included in base pricing. Heavy accumulation requiring additional cleaning: $75 to $150 additional.

Annual Sweep

For Lexington homeowners with occasional fireplace use, one annual sweep before burning season is standard. For wood-stove-primary heating, we recommend mid-season and end-of-season sweeps. The National Fire Protection Association recommends annual inspection for all chimneys; sweeping frequency depends on use. Our annual sweep includes Level 1 inspection, debris removal, and a condition report. Cost: $189 to $279.

Fireplace Cleaning

Fireplace cleaning addresses the firebox, smoke chamber, and damper assembly, not just the flue. In Lexington’s older homes, we often find damaged or missing throat dampers, cracked firebrick, and smoke chambers that were parged with inferior mortar now falling away. We clean and assess, then report what needs attention. Fireplace cleaning runs $159 to $229 as a standalone service, or bundled with flue sweeping.

Trusted Brands We Service in Lexington

We don’t use builder-grade substitutes. For liner installations and repairs in Lexington, we specify DuraFlex stainless steel liners, HeatShield cerfractory flue resurfacing, and Famco chimney caps and dampers. These are the brands that professional sweeps specify when the job has to last. We stock common sizes and profiles locally, so most Lexington repairs don’t wait on shipping. When a HeatShield liner is the right solution for a pre-liner brick flue, we size it to the existing opening rather than forcing a standard clay-tile dimension that won’t seal. And when a cap needs to pass Historic Districts Commission review, we select from profiles that balance ventilation requirements with visual appropriateness.

Common Chimney Cleaning & Sweep Problems We See in Lexington Homes

• Brushes sized for modern clay-tile flues skip the mortar joints and wide corners of Lexington’s pre-liner brick chimneys, leaving second-degree creosote behind. We hand-brush these wide flues with custom-sized polypropylene brushes, then camera-verify the surface is clean. A standard sweep on an unlined colonial flue takes longer and costs more, but doing it half-clean is not doing it at all.
• Sweeps trained on oil-era single-flue houses miss the abandoned, soot-laden oil flue left open at the top after a gas conversion, letting animals in and cross-drafting the adjacent fireplace flue. Lexington’s widespread oil-to-gas conversions have left thousands of these orphaned flues. We check every flue termination from the roof and cap or line abandoned flues as needed.
• Local freeze-thaw cycling spalls lime mortar and cracks crowns far faster than in harbor towns, so a sweep that doesn’t check the crown and flashing returns a chimney that leaks by spring. Lexington sits inland in Middlesex County without coastal temperature buffering. Hard winters here open mortar joints and crown cracks that harbor moisture, then expand it. We inspect crown and flashing on every sweep.
• Third-degree creosote glaze in wood-stove-primary homes reaches hazardous levels faster than most owners expect. Lexington’s rural properties and older homes with supplemental wood heat often burn green or unseasoned wood, accelerating glaze formation. We test for glaze depth and recommend rotary removal or chemical treatment before the burning season peaks.
