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
Chimney cap and crown work in Lexington runs $450-$1,800 depending on whether we’re fitting a new cap on a mid-century modernist chimney with minimal roof clearance or rebuilding a spalled crown on a pre-Revolutionary masonry stack near the Battle Green. Our crews carry Famco and Copperfield caps sized for both extremes, and every job starts with a camera scan and written price. Call (857) 309-1908 to book.
Why Lexington Homes Are Different
Lexington’s housing stock spans two extremes rare in combination. Near the Battle Green, pre-Revolutionary War masonry chimneys built with lime mortar face decades of freeze-thaw damage that turns routine sweeps into masonry assessments. In the modernist planned communities of Six Moon Hill and Five Fields, Gropius-era architects prioritized sculptural form over conventional flue geometry, leaving chimneys that barely satisfy the 2-foot-above-10-foot rule and produce heavier creosote glazing than outsiders expect.
The inland climate drives this further. Colder average lows and heavier snowpack than coastal towns at similar latitude extend the wood-burning season from October through late April, accelerating creosote accumulation while winter freeze-thaw cycles attack aging mortar joints. Technicians here shift between 18th-century lime-mortar diagnosis and troubleshooting under-drafted modernist fireplaces, a pairing found nowhere else in the metro area.
Our Main Lexington Services
Most Lexington calls fall into three categories. Jump to yours below:
Chimney Cleaning & Sweep in Lexington
We clean and inspect chimneys across all three Lexington housing tiers, from colonial-era flues with degraded clay tile to modernist stacks with marginal draft. Every sweep includes NFPA 211 Level 2 camera inspection and a documented photo record under Haven Standard Clause 4. Chimney Cleaning & Sweep in Lexington covers seasonal maintenance, creosote removal, and combustion analysis for the extended burning season this inland climate demands.
Chimney Repair in Lexington
Repair work in Lexington means matching materials to era: lime-mortar repointing for pre-1900 stacks, crown rebuilds for 1950s-1970s Capes, and draft correction for Six Moon Hill’s low-clearance chimneys. We source through Haven’s buying network to keep prices honest. Chimney Repair in Lexington details our masonry, crown, and structural work.
Fireplace Services in Lexington
Fireplace service in Lexington addresses the shallow fireboxes common in mid-century modernist design, which burn dirtier than deeper units, plus the aging factory-built inserts in postwar colonials. We inspect, clean, and repair fireboxes, dampers, and smoke chambers. Fireplace Services in Lexington has the full scope.

BeforeAfterChimney Cap & Crown in Lexington
Cap and crown work in Lexington demands material choices matched to housing era. Pre-Revolutionary chimneys near the Battle Green need crowns that breathe with lime-based mortar, while mid-century modernist stacks in Six Moon Hill require low-profile caps that won’t catch wind on minimal roof clearances. Chimney Cap & Crown covers our full product range; here’s what we do most often in Lexington.
Cap Replacement
Signs you need it
Rust streaks on the chimney face, visible mesh deterioration, or animal entry in cap gaps.
What it costs in Lexington
Cap replacement in Lexington typically runs $450-$850 for standard single-flue models, with multi-flue or custom-fit caps for modernist chimneys reaching $1,200-$1,800.
How we do it
We measure the flue and crown footprint, select a Famco or Copperfield cap with proper mesh clearance, and secure it with stainless fasteners that won’t back out during freeze-thaw cycles.
Crown Repair
Signs you need it
Cracking, spalling concrete, or water pooling on the crown surface after rain.
What it costs in Lexington
Crown repair in Lexington ranges $650-$1,200 for partial resurfacing, with full crown rebuilds on historic chimneys running $1,400-$1,800 due to lime-mortar matching and formwork complexity.
How we do it
We grind out compromised material, apply a bonding layer, and pour new crown concrete sloped 2 inches minimum from the flue with a drip edge to direct water away from brickwork.
What Chimney Cap & Crown Costs in Lexington
| Item | Typical range in Lexington |
|---|---|
| Single-flue cap replacement | $450 - $850 |
| Multi-flue or custom cap | $1,200 - $1,800 |
| Crown repair (partial) | $650 - $1,200 |
| Full crown rebuild | $1,400 - $1,800 |
How long does a chimney cap last in Lexington?
Stainless steel caps last 15-25 years in Lexington’s climate; galvanized models often fail at 7-10 years due to snowpack and salt air drifting inland. We quote cap material grade in writing before installation.
Can a cracked crown wait until spring?
Small hairline cracks can be monitored if the flue is dry, but open cracks through freeze-thaw cycles accelerate spalling and leak water into the smoke chamber. We document crown condition with photos so you can decide from evidence, not pressure.
Chimney Liner & Rebuild in Lexington
Liner and rebuild work in Lexington means different failures across housing eras: cracked clay tile in 1950s-1970s Capes, corrosion in modernist chimneys venting efficient appliances, and complete relining when pre-1900 chimneys lose mortar between wythes. Chimney Liner & Rebuild details our full capabilities; below are the Lexington-specific jobs we handle.
Stainless Steel Liner
Signs you need it
Flue tiles visible in pieces at the cleanout, or a Level 2 camera scan showing gaps between tile sections.
What it costs in Lexington
Stainless steel liner installation in Lexington runs $2,800-$4,500 for a typical single-flue system, with complex drops through offset smoke chambers adding labor.
How we do it
We measure the flue with a video scan, order DuraFlex or Olympia Chimney liner cut to length, and drop it with an insulation wrap rated to UL 1777 for zero-clearance performance.
Partial Rebuild
Signs you need it
Spalled brick above the roofline, leaning stack, or mortar missing to finger depth between wythes.
What it costs in Lexington
Partial rebuilds in Lexington range $3,500-$6,500 depending on height and whether historic lime-mortar matching is required for pre-1900 chimneys near the Battle Green.
How we do it
We scaffold to working height, remove damaged courses to sound brick, and rebuild with mortar matched to era, documenting each stage with photos under Haven Standard Clause 4.
What Chimney Liner & Rebuild Costs in Lexington
| Item | Typical range in Lexington |
|---|---|
| Stainless steel liner (single flue) | $2,800 - $4,500 |
| Flexible liner for offset flue | $3,200 - $5,000 |
| Partial chimney rebuild | $3,500 - $6,500 |
| Full chimney rebuild | $8,000 - $15,000 |
Does every old chimney need a new liner?
No. Many pre-1900 Lexington chimneys vent properly if mortar joints are sound and the flue is appropriately sized for the appliance. We run a camera scan first and show you the footage before recommending any liner work.
How long does a stainless liner last?
Properly installed 316Ti stainless liners carry a lifetime warranty and typically outlast the appliance they serve; we document installation with photos and a written warranty under Haven Standard Clause 1.

We stock caps, liners, and repair materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield through Haven’s buying network. Most common Lexington sizes ship to our Boston office within 48 hours, keeping scheduled work on track.
