We’ve been answering calls with a live person, 24 hours a day, for over 42 years. Russell Haines built Hearthstone Chimney Co. on the principle that a sweep should explain what he found, show you the photos, and give you a plain-English verdict you can act on or sleep on. In Lexington, that steady approach matters more than most places. The town’s colonial-era housing stock, its mature oak-and-maple canopy, and the hard use its wood stoves see through New England winters all demand a technician who measures before ordering parts and maps a flue before running a brush through it.

Why Hearthstone Chimney Co. Is Lexington’s Preferred Chimney Cleaning & Sweep Company

Lexington homeowners tend to stay put. They’ve lived in their houses twenty, thirty, sometimes forty years, and they’ve learned to spot a contractor who talks faster than he works. We don’t. Our 90-Day Done Right Promise - in writing, no arguing - means if we miss something, we come back. No paperwork shuffle, no “we’ll see what we can do.”

Our Boston office coordinates dispatch to Lexington directly. Crews know the difference between a 1950s ranch off Woburn Street and a 1760s colonial on Clarke Street, and they carry the equipment for both. Background-checked, uniformed technicians complete most jobs in one visit. Upfront pricing means the number on the estimate is the number on the invoice.

We answer the phone live, every hour of every day. Not a callback queue. Not an app. A person.

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 standard masonry fireplaces and wood stoves in newer construction - the 1960s-1980s ranches and split-levels that make up much of the town’s suburban ring. The technician examines readily accessible portions of the chimney exterior, interior, and connecting appliance. No tools required, no disruption to your day. If we find reason to look deeper, we’ll show you the photo and explain why a Level 2 is warranted before proceeding.

Level 2 Inspection

Level 2 is where we do our real work in Lexington. This camera inspection covers all accessible portions of the chimney, including attics, crawl spaces, and the full flue length. We document with photos you can see and deliver a plain-English verdict. For colonial homes near the Battle Green, along Massachusetts Avenue, or on Percy Road, this is non-negotiable. Those chimneys often serve multiple original hearth openings on stacked floors through shared flue passages - a colonial construction pattern that creates cross-contamination risk if not mapped before cleaning. We measure every flue physically. No sizing chart substitutes for a tape measure and a camera in a 250-year-old chimney.

On Clarke Street just off the Battle Green, we swept a 1700s colonial whose rubble-stone-base chimney served two original stacked hearths through one shared flue passage; we mapped the passages first, pulled a heavy fall load of oak leaf debris, then removed first-degree creosote and treated a spalling crown with HeatShield before checking the smoke chamber and damper on both fireboxes. That’s the standard we apply.

Creosote Removal

Lexington’s rural properties and homes with wood stoves as primary heat source see far heavier creosote loading than occasional-fireplace households. Long, smoldering burns - the efficient, low-flame burn many wood-stove owners favor - produce third-degree creosote, a tar-like glaze that standard wire brushes won’t touch. We see this regularly in homes off the older stretches of Massachusetts Avenue and in the more wooded pockets toward Bedford. Our technicians identify the creosote stage before choosing the method: rotary cleaning, chemical treatment, or controlled mechanical removal. Treating third-degree buildup as a routine brush job is how chimneys catch fire. We don’t guess.

Soot Removal & Annual Sweep

For standard fireplaces and well-maintained wood stoves, an annual sweep removes soot, light creosote, and the debris that accumulates through a Lexington winter. The town’s dense canopy of mature oaks and maples means heavy leaf and debris loads each fall. That material restricts draft and accelerates creosote buildup by disrupting proper airflow. A restricted flue burns dirtier. We remove the debris, inspect for damage, and give you an honest read on whether your burning practice is helping or hurting. Done right - and we stand behind it.

Trusted Brands We Service in Lexington

We stock professional-grade materials from Olympia Chimney, Famco, and DuraFlex - no builder-grade substitutes. For Lexington’s colonial chimneys with irregular flue geometry, that means we can fabricate or specify custom solutions rather than forcing a stock liner into a hand-laid passage that won’t accept it. Famco caps and Olympia Chimney components handle the town’s weather exposure and freeze-thaw stress without the premature failure we’ve seen on generic hardware-store units. Parts on the truck mean faster turnaround, and faster turnaround means you’re not waiting two weeks with a questionable flue while a part ships from a warehouse.

Common Chimney Cleaning & Sweep Problems We See in Lexington Homes

• Freeze-thaw mortar degradation on colonial chimneys. Lexington’s temperatures cross 32°F repeatedly through winter, and that cycle attacks lime mortar joints far more aggressively than Portland cement. We inspect for spalling and joint erosion during every sweep, and we document it with photos so you can see whether the damage is cosmetic or structural.
• Shared flue passages in pre-Revolutionary homes. Chimneys serving stacked hearths on multiple floors create draft interference and cross-contamination risk. We map these passages with camera inspection before cleaning, and we never recommend a liner without physical measurement of the irregular interior geometry.
• Third-degree creosote from wood-stove primary heating. Rural Lexington properties burning six to eight months a year accumulate glazed creosote that requires rotary or chemical pretreatment. A standard brush pass won’t remove it and can polish it into a harder, more dangerous layer.
• Heavy leaf and debris blockage from mature canopy. The oaks and maples that define Lexington’s landscape shed directly into uncapped or poorly capped flues. We remove the debris, check for resulting draft restriction, and recommend proper cap protection using materials that won’t corrode or blow off in the first nor’easter.
