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 Homes Are Different
Lexington’s historic core around the Battle Green holds one of the densest concentrations of pre-1775 center-chimney colonials in Massachusetts. These homes carry massive multi-flue brick stacks built to serve four to six fireplaces plus a cooking hearth in a single chase. Sweeps must map configurations rarely seen in Burlington or Bedford, and any exterior work on properties under the Historic Districts Commission requires permits that govern materials and methods.
The postwar belt of 1950s-1970s ranches and garrison colonials tells a different story. Many converted from oil to gas, leaving clay tile flue liners unsized for new appliances. The acidic condensate eats those liners from inside while eastern Massachusetts freeze-thaw cycles, with temperatures crossing 32°F dozens of times each winter, erode soft lime mortar and heave flashing joints. Nor’easter ice accumulation on crowns cracks caps and drives water into masonry, accelerating creosote absorption.

Before
AfterChimney Cap & Crown in Lexington
Lexington’s freeze-thaw cycles and nor’easter ice loads destroy chimney caps and crowns faster than inland towns. On streets near the Battle Green, we regularly find center-chimney stacks with multiple flues sharing one chase, where a cracked crown lets water saturate brick and accelerate creosote absorption across all flues. Our Chimney Cap & Crown work starts with a camera inspection to map the full system, then quotes the repair in writing before any work begins.

Signs you need it
Rust streaks down the chimney face, visible gaps between cap and flue tile, or animal debris on the smoke shelf indicate cap failure.

Chimney Liner & Rebuild in Lexington
Lexington’s postwar oil-to-gas conversions left thousands of clay tile liners too large for efficient gas appliance venting, causing acidic condensate that erodes flue walls from inside. On pre-1800 homes, original lime-mortared brick flues have often degraded past safe use. Our Chimney Liner & Rebuild service installs properly sized liners with full camera documentation before and after.

How we do it

What it costs in Lexington

How we do it
