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 Company in Lexington, MA
Finding a chimney company in Lexington, MA means finding a crew that understands colonial-era brick and mid-century flue liners equally well. We’re Alcott Chimney Sweep, and our Lexington work spans both: pre-Revolutionary masonry near the Battle Green and 1950s – 1970s tract homes with clay tile liners now past their serviceable life. Lexington’s inland freeze-thaw cycle and its historic district rules make this market unlike any of its neighbors. If you need a chimney sweep, inspection, or gas fireplace repair, call us at (336) 863-3889 and we’ll give you a straight answer.
Why Lexington Homes Are Different
Lexington sits roughly 11 miles inland, which means winter temperatures cross 32°F dozens of times each season. That repeated freeze-thaw cycling spalls soft colonial brick and fractures aging clay tile liners faster than what coastal towns like Winchester or Burlington experience. We see the result every spring: cracked crowns, open mortar joints, and spalled brick faces that owners didn’t notice until a cleaning revealed the damage.
The housing stock compounds this. Lexington’s oldest homes, concentrated around the Battle Green and the historic center, were built with lime-based mortar and handmade brick. Modern Portland cement repointing will crack and spall that old brick, which is why the Local Historic Districts Commission requires historically compatible lime mortars for exterior chimney work on designated properties. Visible alterations may need HDC review before we touch a brick. That’s a regulatory reality we plan for from the first visit. Meanwhile, Lexington’s postwar Capes, Colonials, and split-levels, built largely in the 1950s through 1970s, now carry clay tile flue liners at or past their 50 – 70 year lifespan. Those liners crack, smoke chambers deteriorate, and single-flue configurations create venting conflicts when homeowners add gas inserts or sealed high-efficiency furnaces.
Our Main Lexington Services
Lexington homeowners call us most often for two things: annual sweeps to stay safe through burning season, and inspections when a house is changing hands or a fireplace hasn’t been used in years. Gas fireplace repair rounds out the third, and it’s become a steady part of our Lexington work as more homes convert from wood.
Chimney Sweep in Lexington
A Chimney Sweep in Lexington means removing creosote, the tar-like buildup that causes chimney fires, from flues that range from colonial-era masonry to mid-century clay tile. We also clear the smoke chamber and check the damper while we’re there. Lexington’s freeze-thaw cycle means we often find spalled brick debris inside the flue that needs to come out before you burn again. Every sweep finishes with a written report of what we found.
Chimney Inspection in Lexington
Our Chimney Inspection in Lexington goes beyond a visual once-over. We run a camera through the flue so you can see exactly what’s there: cracked tiles, open mortar joints, or creosote buildup at the smoke shelf. On Lexington’s older homes, we pay close attention to lime mortar condition and any previous Portland cement repairs that may have caused spalling. You get a written report with photos and a plain-English explanation of what needs work now and what can wait.
Gas Fireplace Repair in Lexington
When a gas fireplace stops lighting or burns yellow instead of blue, our Gas Fireplace Repair in Lexington service covers the full diagnostic: thermocouples, thermopiles, valves, burners, and venting. Lexington’s postwar homes often share a single masonry flue between the furnace and fireplace, which creates venting conflicts when a gas insert goes in. We’ll tell you plainly if a repair is enough or if the venting needs reconfiguring before it’s safe.
