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.

AfterChimney Cleaning in Lexington, MA
A Level 2 chimney inspection and cleaning in Lexington typically costs $280-$380 and includes a camera scan of the flue, a written price before any work starts, and a documented photo record. Homes near the Battle Green and along Massachusetts Avenue often contain colonial-era chimney stacks with multiple unmapped flues, so we routinely perform smoke-testing before brush work begins. Call (781) 649-9326 to book a visit or request a free second opinion on any written estimate.
Why Lexington Homes Are Different
Lexington’s inland position strips away Boston’s ocean moderation, producing harsher freeze-thaw cycles than coastal towns. This accelerates spalling in lime mortar joints and cracking of chimney crowns, compounding the vulnerability of masonry that predates modern Portland cement. The town holds one of Massachusetts’s oldest intact housing stocks, with colonial homes near the Battle Green dating to the 1700s. These chimneys were built before clay-tile liner standards, frequently contain three or four stacked flues in a single mass, and were laid with lime mortar that deteriorates faster than modern mixes. Post-WWII ranches and split-levels on Lexington’s outer edges present the opposite problem: single oil-furnace flues, many now orphaned after conversions to gas, left uncapped and open to water intrusion.

Chimney Repair in Lexington
We repair spalling mortar, cracked crowns, and deteriorated flashing using materials from our Haven buying network. Lexington’s freeze-thaw severity means crown damage progresses faster here than in coastal towns, so we prioritize water-stopping repairs before full rebuilds. Chimney Repair in Lexington

AfterChimney Cap & Crown in Lexington
Lexington’s colonial chimney stacks, with their multiple flues and aged lime mortar, depend on intact caps and crowns to survive the town’s severe freeze-thaw cycles. A failed crown lets water into the chimney mass, where freeze expansion opens mortar joints and destabilizes the entire structure. We install and repair caps and crowns using materials from Copperfield and Famco, with every job quoted in writing before work begins under Haven Standard Clause 1. Chimney Cap & Crown
Cap Installation
Signs you need it
Your flue is open to rain, birds, or debris, or you notice rust streaks on the chimney face from a missing or deteriorated cap.
What it costs in Lexington
Single-flue cap installation runs $180-$340; multi-flue caps for Lexington’s historic chimney stacks range $340-$620.
How we do it
We measure the flue or flues, fabricate or order the correct cap from Copperfield or Famco, and secure it with stainless steel fasteners rated for Massachusetts wind loads.
Crown Repair
Signs you need it
You see cracks in the concrete crown surface, pieces missing at the edges, or water staining on interior chimney walls below the roofline.
What it costs in Lexington
Crown crack sealing and minor repair costs $280-$480; full crown replacement for deteriorated colonial-era chimneys ranges $1,200-$2,400.
How we do it
We grind out cracked material, apply a bonding layer, and pour new crown concrete sloped to shed water, with expansion joints positioned to match the flue layout.
What Chimney Cap & Crown Costs in Lexington
| Item | Typical range in Lexington |
|---|---|
| Single-flue cap installation | $180-$340 |
| Multi-flue cap installation | $340-$620 |
| Crown crack repair | $280-$480 |
| Full crown replacement | $1,200-$2,400 |
Do I need a cap for every flue in my chimney?
Yes, every active flue needs its own cap or a properly sized multi-flue cap. In Lexington’s historic homes with three or four flues in one mass, an uncovered flue lets water accelerate mortar deterioration in the shared chimney structure.
How long does a crown repair last?
A properly poured crown with correct slope and expansion joints lasts 15-25 years. Lexington’s freeze-thaw severity makes proper installation critical; quick patches without slope or bonding layer typically fail within two winters.
Chimney Liner & Rebuild in Lexington
Lexington’s colonial-era chimneys were built before clay-tile liner standards, and many still vent fireplaces and appliances through unlined or deteriorated flues. The town’s severe freeze-thaw cycling accelerates liner failure once cracks form, allowing combustion gases to reach surrounding masonry. We install stainless steel and flexible liners and perform partial or full rebuilds, with every job documented under Haven Standard Clause 4. Chimney Liner & Rebuild
Stainless Steel Liner
Signs you need it
Your clay tile liner is cracked, flaking, or missing pieces, or a Level 2 camera inspection shows gaps between tile sections.
What it costs in Lexington
Stainless steel liner installation for a single fireplace flue ranges $2,800-$4,800; multi-flue historic installations run $4,800-$8,200.
How we do it
We measure the flue with a video scan, order DuraFlex or Olympia Chimney liner sized to the appliance, and drop it with proper insulation and top termination.
Partial Rebuild
Signs you need it
The upper courses of your chimney are spalling, the crown is detached, or the structure leans above the roofline while the lower masonry remains sound.
What it costs in Lexington
Partial rebuild of a chimney above the roofline typically costs $3,400-$6,800, depending on accessibility and the number of flues.
How we do it
We dismantle to sound masonry, salvage usable brick where possible, and rebuild with matching materials and proper flashing integration at the roofline.
What Chimney Liner & Rebuild Costs in Lexington
| Item | Typical range in Lexington |
|---|---|
| Stainless steel liner, single flue | $2,800-$4,800 |
| Stainless steel liner, multi-flue | $4,800-$8,200 |
| Partial chimney rebuild | $3,400-$6,800 |
| Full chimney rebuild | $8,200-$16,000 |
Can I use my fireplace with a cracked clay liner?
No, cracked clay liners allow combustion gases and creosote to reach combustible framing. In Lexington’s unlined colonial chimneys, this condition is common and requires liner installation before safe use.
How do I know if I need a partial or full rebuild?
A Level 2 camera scan and exterior structural assessment determine this. If damage is confined above the roofline and lower masonry is sound, partial rebuild suffices; if the foundation or multiple courses are compromised, full rebuild is necessary.

FAQs About Chimney Cleaning in Lexington
Most chimney repairs and liner installations require a building permit from the Lexington Building Department; we handle permit applications as part of our scope when they’re needed for the work we quote. Routine cleaning and inspection do not require permitting.
NFPA 211 recommends annual Level 2 inspection for all chimneys, and Lexington’s aged masonry and severe freeze-thaw cycles make this especially prudent. Homes with active wood-burning fireplaces may need sweeping more frequently depending on use and creosote accumulation.
Yes, we regularly work on colonial-era homes near the Battle Green and along Massachusetts Avenue. We use appropriate materials and techniques for historic masonry, and we document conditions with photo records that can support any historical commission filings if needed.
