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 Lexington Homeowners Choose Hearthstone Chimney Co.
Forty-two years in this business teaches you that homeowners who’ve lived in the same house for twenty or thirty years can spot a salesman from the driveway. Lexington residents tend to be direct - they want to know what’s wrong, what it’ll cost, and whether you’ll still answer the phone if something isn’t right. We built our company on those exact expectations.
The 90-Day Done Right Promise governs every job we do in Lexington: Krafted right, Every time, Your home first, Standing behind it. If it’s not right, we come back and make it right - in writing, no arguing, no paperwork chase. That promise has been our standard since 1984, and it doesn’t expire because a job is finished.
Our Level-2 camera inspections end with photos you can see on the spot and a plain-English verdict documented like an engineer, explained like a craftsman. Nothing gets recommended without evidence you can examine yourself - not a new liner, not crown work, not masonry repair. When something can safely wait, we say so plainly.
You’ll find us working regularly in the Battle Green area, where pre-1820 chimneys demand particular care, and across the neighborhoods near Lexington Center and along Marrett Road, where the 1950s and 1960s housing stock presents its own set of flue conditions. Background-checked, uniformed technicians arrive with professional-grade materials from DuraFlex, HeatShield, and Famco - no builder-grade substitutes, no surprises on the bill.
Chimney Cleaning Services We Offer in Lexington
Chimney Cleaning & Sweep
Our standard sweep removes creosote, soot, and obstructions from wood-burning and gas appliance flues, with debris contained by HEPA vacuum systems so your house stays clean. We inspect the firebox, damper, and accessible flue lining for deterioration during every cleaning. Learn more about our Chimney Cleaning & Sweep in Lexington.
Chimney Repair
Crown cracking, spalling brick, and deteriorated mortar joints accelerate in Lexington’s hard freeze-thaw cycles, especially on the lime-mortar chimneys of the oldest homes. We rebuild crowns with poured concrete or specialized crown coat systems, and we repoint mortar using mixes matched to the original construction. Learn more about our Chimney Repair in Lexington.
Fireplace Services
Firebox refractory panel replacement, smoke chamber parging, and damper repair or replacement - we handle the components that see direct fire and wear. Gas log set installation and troubleshooting for direct-vent and vent-free units are also available. Learn more about our Fireplace Services in Lexington.
Chimney Cap & Crown Installation
A proper cap keeps Lexington’s heavy snowfall and the wildlife of Middlesex County out of your flue while allowing proper draft. We fabricate and install stainless steel and copper caps with spark arrestors, plus concrete crown pours and crown coat applications for existing crown protection.
Chimney Liner & Rebuild
Oil-to-gas conversions across Lexington have left many chimneys with oversized, unlined flues no longer suited to modern appliance output. We install stainless steel liners from DuraFlex and HeatShield, sized correctly for the appliance and documented with before-and-after camera footage.

Why Lexington’s Climate & Housing Affect Chimney Cleaning
Lexington sits inland in Middlesex County without the coastal temperature moderation that protects harbor towns like Marblehead. That means harder freeze-thaw cycling, and harder freeze-thaw cycling destroys lime mortar faster than anything else. The colonial and Federal-period homes near the Battle Green - some with chimneys predating modern clay-liner requirements entirely - were built with lime mortar and no tile insert, a construction type nearly absent in neighboring Burlington or Woburn. We see crown and mortar-joint deterioration run years ahead of schedule on these chimneys, and the above-average interior snowfall accumulation accelerates cap cracking and moisture infiltration into aging brick.
The widespread oil-to-gas furnace conversions happening across Lexington add another layer. Homeowners convert the furnace but leave the oversized, soot-laden oil flue in place, often still open at the top. We regularly find these abandoned flues creating animal entry points and cross-draft problems in the adjacent fireplace flue - a combination problem specific to this era of Middlesex County housing. A standard sweep catches the creosote, but recognizing the cross-flue interaction takes a sweep who has seen this exact pattern before.
For properties in the Battle Green and Lexington Center historic districts, the Historic Districts Commission holds authority over exterior alterations visible from public ways. Liner and cap solutions on registered properties must be chosen with that review process in mind, and we document our recommendations accordingly.

FAQs About Chimney Cleaning in Lexington
A standard chimney cleaning and Level-1 inspection in Lexington typically costs between $189 and $289, with most homeowners paying near the middle of that range.

The National Fire Protection Association recommends annual inspection for all chimneys, with cleaning frequency determined by use and fuel type. In Lexington, we find that wood-burning fireplaces used as primary heat sources need sweeping every cord of wood burned, while occasional-use fireplaces often stretch to every two years if inspected annually. The oil-to-gas conversion chimneys common in Lexington’s 1950s-1970s neighborhoods need particular attention - the abandoned oil flue can obstruct or interact with the active fireplace flue even when the fireplace itself sees light use.
Not unless there’s documented evidence of a problem. We recommend liner replacement only when camera inspection shows cracked clay tiles, gaps between tile sections, or flue sizing mismatched to the appliance - and we show you the photos before proposing any work. In Lexington’s pre-1820 chimneys near the Battle Green, some unlined brick flues remain serviceable with proper maintenance, while others have deteriorated past safe use. We’ll tell you plainly which category yours falls into, and we’ll note when work can safely wait a season.
Skipped maintenance leads to creosote accumulation, which is combustible and the leading cause of chimney fires. In Lexington’s hard freeze-thaw climate, deferred cleaning also means deferred inspection - small crown cracks and mortar joint gaps grow through winter cycles, admitting water that accelerates deterioration and can damage interior walls and framing. Carbon monoxide risk rises if flue obstructions or liner gaps allow exhaust to enter living space. The cost of prevention is modest; the cost of remediation after failure is not.
Yes, and we understand the particular requirements. Chimneys in the Battle Green and Lexington Center historic districts were built with lime mortar and wide, multi-flue construction that demands gentler cleaning methods and informed material choices. For registered properties, exterior alterations visible from public ways may require Historic Districts Commission review, and we document our recommendations with that process in mind. We’ve worked on chimneys predating modern liner requirements and know how to evaluate whether an unlined brick flue remains serviceable or needs intervention.

What Lexington Customers Say
"The cap keeps the birds out now, which after two springs of scratching noises above the bedroom is worth every penny."
- Nisha Gupta"Creosote buildup was worse than I realized. He measured it, put a camera up to show me the glazing on the flue, and was honest that we were closer to a chimney fire than I wanted to hear."
- Mark Bennett"Second property I have had them at. Both times the tech showed me photos from inside the flue before quoting anything."
