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 Boston, MA
A Level 2 chimney inspection and cleaning in Boston typically runs $280-$420 for a standard sweep with camera documentation, while cap, crown, and liner work on the city’s aging triple-decker and rowhouse stock often reaches $1,800-$6,500 depending on flue count and masonry condition. We’re Level Two Chimney Co., and we dispatch crews from our Boston office to handle the multi-flue, unlined chimneys that dominate neighborhoods from Dorchester to South Boston. Call (857) 309-1908 for a written estimate before any work starts.
Why Boston Homes Are Different
Boston’s housing stock is among the oldest urban fabric in the country. The triple-deckers lining streets in Dorchester, Roxbury, Jamaica Plain, and South Boston were built roughly 1870 to 1920, each with a single chimney stack containing multiple flues serving stacked units. These were designed for coal, later converted to oil or gas, and most predate modern liner standards entirely.
That matters because Massachusetts enforces strict chimney liner and venting codes, and a single conversion in one unit can trigger compliance requirements for the entire stack. We’ve seen first-floor landlords switch from oil to gas mid-tenancy, only to have the Level 2 inspection reveal the flue is now undersized for the combined load - a cascade building owners rarely anticipate.
Climate compounds the problem. Boston’s freeze-thaw cycles grind away mortar joints, while salt air in Charlestown, East Boston, and South Boston corrodes metal components faster than inland New England cities. A cap that lasts fifteen years in Worcester might need replacement in ten here.

BeforeAfterChimney Cap & Crown in Boston
Boston’s exposed chimney stacks take a beating. Freeze-thaw cycles open mortar joints, salt air attacks metal components, and the city’s dominant triple-decker stock means one failed crown can expose three units to water intrusion. We install and repair caps and crowns across the metro, and you can explore all cap and crown options at our Chimney Cap & Crown hub.
Crown Repair
Signs you need it
Hairline cracks in the concrete crown, water staining on interior chimney walls, or pieces of crown material in the firebox.
What it costs in Boston
Crown repair typically runs $650-$1,400 depending on accessibility and whether the flue tiles need resetting.
How we do it
We grind out cracked material, apply a bonding agent, and pour new crown concrete with a minimum 2-inch overhang and drip edge, documented with before-and-after photos.
Cap Installation
Signs you need it
Rust holes in an existing metal cap, missing spark arrestor, or evidence of animal entry like nesting debris or droppings in the flue.
What it costs in Boston
Single-flue cap installation ranges $280-$550; multi-flue caps for triple-decker stacks run $480-$920.
How we do it
We measure the flue or crown footprint, fabricate or source a stainless-steel or copper cap with proper mesh sizing, and secure it with masonry anchors or a skirted base seal.
What Chimney Cap & Crown Costs in Boston
| Item | Typical range in Boston |
|---|---|
| Crown repair | $650 - $1,400 |
| Single-flue cap installation | $280 - $550 |
| Multi-flue cap installation | $480 - $920 |
How long does a chimney crown last in Boston?
A properly poured concrete crown with overhang and drip edge lasts 15-25 years in Boston, though salt-air exposure in coastal neighborhoods can shorten that by 3-5 years. Annual inspection catches cracks before water penetrates.
Can you install a cap on a triple-decker chimney?
Yes, we fabricate and install multi-flue caps sized for Boston’s shared-stack chimneys, with separate screened compartments for each flue to prevent cross-drafting. Call (857) 309-1908 for exact measurements and pricing.
Chimney Liner & Rebuild in Boston
Most Boston chimneys were built unlined or with deteriorated clay tile never meant for modern appliances. When a Dorchester triple-decker’s first floor converts to high-efficiency gas, the existing flue may be oversized and unlined - a code violation that affects every tenant’s safety. We reline and rebuild to bring these stacks into compliance.
Stainless Steel Liner
Signs you need it
Clay tile fragments in the firebox, visible gaps in the flue wall on camera inspection, or a new appliance installation requiring UL-listed venting.
What it costs in Boston
Stainless steel liner installation runs $2,400-$4,800 for a single flue, with multi-flue triple-decker projects at $4,200-$7,500.
How we do it
We drop a custom-measured, insulated stainless-steel liner down the flue, connect it to the appliance with a proper tee and top plate, and pressure-test the joint seals.
Partial Rebuild
Signs you need it
Significant brick spalling above the roofline, a leaning stack, or mortar loss deep enough to expose the flue liner to weather.
What it costs in Boston
Partial rebuild of the upper stack typically costs $3,200-$6,500 depending on height, scaffolding needs, and matching historic brick.
How we do it
We dismantle to sound masonry, install temporary bracing if needed, and rebuild with matching brick and Type N or Type S mortar appropriate to the original construction.
What Chimney Liner & Rebuild Costs in Boston
| Item | Typical range in Boston |
|---|---|
| Stainless steel liner (single flue) | $2,400 - $4,800 |
| Stainless steel liner (multi-flue) | $4,200 - $7,500 |
| Partial rebuild (upper stack) | $3,200 - $6,500 |
Is an unlined chimney illegal in Massachusetts?
Massachusetts building code requires lined chimneys for all solid-fuel and most gas appliances; unlined or deteriorated clay-tile flues fail inspection and can void insurance coverage. We document liner condition with camera footage under Haven Standard Clause 4.
Can one tenant’s conversion force relining for the whole building?
Yes, in Boston triple-deckers a single unit’s appliance change can alter the flue’s temperature and pressure profile, requiring the entire shared stack to meet current venting codes. Our inspection identifies these cascade triggers before you commit to the conversion.

FAQs About Chimney Cleaning in Boston
During peak burning season (September through November), we typically book 3-5 days out; off-peak appointments are often available within 1-3 days. Emergency blockage or animal removal calls get same-day triage through our 24/7 live phone line.
Most chimney repair and relining work requires a permit from the City of Boston Inspectional Services Department; we pull permits as part of our standard workflow and include the documentation in your job packet. Historic district properties in Back Bay or Beacon Hill may need additional review.
We need roof access and entry to each served appliance to complete a full NFPA 211 Level 2 inspection, but we can inspect individual flues from the roof with tenant permission for that unit. Building owners should coordinate access across all units for the most complete documentation.
