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 Boston, MA
Alcott Chimney Sweep handles chimney cleaning, inspection, and gas fireplace repair across Boston, from triple-decker flues in Dorchester to brownstone stacks in Back Bay. Most Boston chimneys predate 1940 and were built for coal or oil heat, which means the work here rarely looks like a standard suburban sweep. Freeze-thaw cycles, salt air near the harbor, and multi-unit flue stacks change how we approach every job. If you need a chimney company in Boston that explains what you’re actually paying for before any work starts, call (336) 863-3889.
Why Boston Homes Are Different
Boston’s triple-deckers define the local chimney challenge. In Dorchester, South Boston, Jamaica Plain, and Roxbury, a single masonry chase often contains three or four separate flues serving different units. Originally built for coal or oil heat, many of those flues are now abandoned or improperly adapted for gas appliances. Massachusetts code under 248 CMR requires a correctly sized liner whenever a heating appliance changes fuel type, so multi-flue relining is routine work here and nearly unheard of in single-family suburbs.
The housing stock compounds the issue. Most residential buildings in Boston date before 1940, with a heavy concentration of 1880s to 1920s triple-deckers and brick row houses in Back Bay, the South End, and Beacon Hill. Many retain original unlined rubble-stone or brick flues that were never designed for a modern furnace or water heater. Add roughly 43 inches of annual snow and dozens of freeze-thaw cycles each winter, and you get accelerated spalling and cracked mortar joints in chimneys that are already over a century old.
Harbor-adjacent neighborhoods like East Boston, South Boston, and the Waterfront face another layer: salt air corrodes mortar and metal liner components faster than inland cities. And in historic districts like Back Bay and Beacon Hill, exterior chimney alterations can trigger preservation commission review, which affects how and where caps or liners get installed.
Our Main Boston Services
Boston homeowners call us most often for two things: a thorough sweep and an honest inspection. Gas fireplace repair runs a close third during the heating months. Each service has its own Boston page with full pricing and details.
Chimney Sweep in Boston
A standard Chimney Sweep in Boston removes creosote, the tar-like buildup that causes chimney fires, from flues that often haven’t been touched in decades. In multi-unit triple-deckers, we sweep each flue independently rather than assuming uniform condition throughout the shared stack. The third-floor flue is frequently in better shape than the first-floor run, which collects the most moisture and acidic condensate. You get a written price before we start and a live person on the phone if you call at 11 p.m. with a smoke smell.
Chimney Inspection in Boston
Our Chimney Inspection in Boston documents what’s actually happening inside your flue with camera footage you can see for yourself. That matters in a city where unlined 1920s brick flues are common and historic preservation rules constrain repair options. We inspect each flue in a multi-unit Boston stack independently, because the bottom flue and top flue age differently. You’ll know your technician’s name and see their photo before we arrive, and the technician shows a photo ID badge at the door, every time.
Gas Fireplace Repair in Boston
Gas Fireplace Repair in Boston covers pilot assemblies, thermocouples, gas valves, and venting issues in units that often sit idle for most of the year. Boston’s older gas conversions, especially in triple-deckers originally heated by coal, frequently have venting that was improvised rather than properly sized. We carry professional trade components from brands like Famco and Copperfield, not box-store substitutes. A written guarantee covers every repair, and if the repair fails within the coverage period, the second visit is free.
