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.

A Level 2 chimney cleaning and sweep in Lexington, MA typically runs $280-$420 and includes a camera-scan inspection with documented photo record.

We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and a significant share of them have been in Lexington’s historic core and its postwar neighborhoods.

We’re not impressed by longevity either. We’re impressed by what we can show you.
Our Chimney Cleaning & Sweep Services in Lexington
Level 1 Inspection
A Level 1 inspection is a visual examination of readily accessible portions of the chimney exterior and interior, plus the appliance and connection. In Lexington’s 1950s-60s ranches and split-levels on the outer edges of town, this is often sufficient for annual maintenance on a single gas or wood-burning appliance with known venting. We check for obstructions, creosote buildup, and basic structural soundness. If your flue is straightforward and your appliance hasn’t changed, a Level 1 with sweep may be all you need.
Typical Level 1 inspection with sweep in Lexington: $180-$260.
Level 2 Inspection
Level 2 is the inspection standard we built our name on. NFPA 211 Level 2 requires camera-scan documentation of the entire flue interior, plus accessible portions of attics, crawl spaces, and basements. In Lexington, this isn’t optional for most homes. The colonial-era masonry near the Battle Green - lime mortar, no clay-tile liner, multiple stacked flues in a single chimney mass - demands it. So do any home sales, new appliance installations, or changes to fuel type.
Our camera goes down every flue. We document spalling mortar, cracked crowns, missing liners, and creosote class. You see what we see. Clause 4 of the Haven Standard requires this photo record on every job; we’ve done it since 2009.
Typical Level 2 inspection with sweep in Lexington: $280-$420.
Creosote Removal
Creosote forms in three classes. First-degree is flaky soot, easily brushed. Second-degree is shiny tar-like flakes, common with restricted air supply. Third-degree is glazed, hardened, and often requires chemical treatment or mechanical removal - not standard brushing. Lexington’s older fireplaces, especially in homes where dampers are left partially closed “to keep heat in,” produce second- and third-degree creosote at higher rates than modern inserts.
We identify creosote class during camera inspection before quoting removal. Third-degree glazed creosote in an unlined flue is a fire hazard; we won’t brush it blindly and dislodge mortar. We show you the camera footage, explain the removal method, and give a written price. Materials from HeatShield and Copperfield are available through our buying network if liner resurfacing or replacement is needed.
Typical creosote removal in Lexington: $220-$380 for first- and second-degree; third-degree glazed removal starts at $450 and may require follow-up visits.
Soot Removal
Soot accumulation restricts draft and can recirculate into living spaces. In Lexington’s postwar homes with orphaned oil flues - common after conversions to gas heat - soot combines with moisture from uncapped tops to form acidic sludge that eats mortar from the inside. We see this regularly in the 1950s ranch belt near Woburn and Burlington lines.
Our sweep includes full soot removal with HEPA-contained vacuums, not a shop vac and a prayer. After cleaning, we camera-inspect to confirm the flue is clear and document the condition for your records.
Typical soot removal with inspection in Lexington: $200-$320.

Same-day resolution on most cap and damper issues.
Common Chimney Cleaning & Sweep Problems We See in Lexington Homes
- Multi-flue central stacks with unknown connections. On a colonial-era home off Massachusetts Avenue near the Battle Green, our tech found a single central chimney mass with four stacked flues - two serving parlor fireplaces, one venting a kitchen hearth, and one orphaned oil flue - none with a modern flue liner. We smoke-tested each flue to map the connections, brushed out first-degree creosote, and showed the homeowner camera footage of spalling lime mortar and a cracked chimney crown before recommending any masonry repair. The owner approved camera-evidenced repointing and an orphan-flue decommissioning; nothing was upsold blind.
- Lime-mortar deterioration accelerated by freeze-thaw. Lexington’s inland location about 11 miles northwest of Boston strips away the ocean’s moderating effect, producing more severe freeze-thaw cycling through winter than coastal towns. This spalls mortar joints and cracks chimney crowns faster. Aggressive brushing in a deteriorated flue dislodges mortar and worsens liner condition. We camera-check first.
- Orphaned and uncapped oil flues in postwar homes. The 1950s-60s ranches and split-levels on Lexington’s outer edges often have single oil-furnace flues abandoned after gas conversion. Left uncapped or improperly decommissioned, they become a draft and moisture path that damages the chimney from inside. We identify these during inspection and quote decommissioning with camera evidence.
- Sweeps who brush the wrong flue. A sweep who doesn’t smoke-test first may brush the wrong flue in a multi-flue central stack, leaving the actual fireplace flue uncleaned and masked by “we swept it.” The homeowner lights a fire unaware. We map before we brush. Every time.

FAQs - Chimney Cleaning & Sweep in Lexington
If your Lexington home was built before 1940, especially near the Battle Green or along Massachusetts Avenue, you need a Level 2 inspection. The NFPA 211 standard requires Level 2 for any chimney with unknown construction, multiple flues, or suspected deterioration - all common in Lexington’s colonial stock. A Level 1 visual check cannot assess lime-mortar condition inside the flue or identify which of four stacked flues serves which fireplace. Call (781) 649-9326 to schedule; we’ll confirm the right inspection level when you book.
Yes, but we camera-inspect first and adjust our method. Unlined lime-mortar flues in 1700s-1800s Lexington chimneys are more fragile than modern clay-tile or stainless steel liners. Aggressive rotary brushing can dislodge spalled mortar and worsen the flue. We use softer brushes or hand tools based on camera findings, and we document every inch. If the flue is too deteriorated for safe sweeping, we show you the footage and quote repair options - never blind. Call (781) 649-9326 for a camera inspection.
Your home likely has a colonial-era central chimney mass built to serve multiple hearths - parlor, kitchen, bedroom - from one large stack. These were standard in Lexington’s pre-1840s construction. Homeowners almost never know which flue connects to which appliance without smoke-testing. We map every flue before brushing. It’s a routine step for us in Lexington, and almost never needed in newer neighboring towns like Burlington. Call (781) 649-9326 and we’ll sort it out on the first visit.
NFPA 211 requires annual inspection of all chimneys, fireplaces, and vents. The inspection level depends on circumstance: Level 1 for annual maintenance with no changes; Level 2 for home sales, new appliance installation, fuel changes, or suspected damage. In Lexington’s historic housing stock, we recommend Level 2 as the baseline because of age, multi-flue construction, and frequent unlined flues. We document every inspection to Clause 4 of the Haven Standard. Call (781) 649-9326 to schedule your annual.
Third-degree glazed creosote can be removed, but standard brushing alone won’t do it. We apply a chemical modifier to break down the glaze, then mechanically remove it over one or two visits. In Lexington’s older unlined flues, we must also assess whether the flue can tolerate the process - another reason we camera-inspect first. If the flue is too deteriorated, we show you the footage and discuss liner options from HeatShield or stainless steel. Nothing is done without camera evidence you can see. Call (781) 649-9326 for an evaluation.
