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
Chimney cap and crown work in Boston runs $450-$1,800 depending on whether we’re sealing a hairline crack or replacing a collapsed crown on a triple-decker in Dorchester. Most Boston homeowners need crown repair or coating before cap replacement, because salt air and freeze-thaw cycles destroy mortar crowns faster than the steel caps sitting on top of them. Call (978) 861-1012 and we’ll quote the exact scope in writing before anyone climbs your roof.
The triple-decker chimney is Boston’s signature problem. Three flues, three condo units, one crumbling crown, and nobody’s quite sure who pays. That’s where we start.
Why Boston Homes Are Different
Boston’s housing stock is among the oldest in the country. Back Bay and South End brownstones went up in the 1860s-1880s with chimneys embedded in shared party walls. Their flues are structurally intertwined with the neighbor’s property, so a routine camera inspection often surfaces damage spanning two deeds. Title review comes before any repair.
The triple-deckers built 1890-1930 across Dorchester, Jamaica Plain, South Boston, and East Boston compound the problem further. These wood-frame buildings share a single masonry chimney venting separate flues for stacked units, now heavily condo-converted. One deteriorating flue, three separate associations, unclear maintenance responsibility.
Climate makes it worse. Salt-laden harbor air accelerates mortar erosion year-round. Dozens of freeze-thaw crossings each winter drive rapid spalling in brick that was already marginal. Nor’easters dump heavy wet snow that saturates aged masonry and expands as it freezes. Many chimneys lack clay tile liners entirely; those that have them are cracked from a century of thermal cycling.
Our Main Boston Services
We handle two core services from our Boston office, plus three additional services with dedicated Boston pages.
Chimney Cleaning & Sweep in Boston
Our Chimney Cleaning & Sweep in Boston service covers NFPA 211 Level 2 inspection with camera documentation on every visit. In Boston’s triple-deckers, we coordinate access across multiple units when flues share a chimney. We document which flue serves which unit and flag any cross-flue leakage that violates fire safety separation.
Chimney Repair in Boston
Our Chimney Repair in Boston service handles spalling brick, deteriorated mortar joints, and structural damage from freeze-thaw cycling. Party-wall chimneys in Back Bay and the South End require careful coordination; we identify shared structural elements before proposing work that affects two properties.
Fireplace Services in Boston
Our Fireplace Services in Boston cover insert installation, gas conversion, and damper repair in historic hearths with non-standard dimensions. Many Beacon Hill and North End fireplaces were built before modern sizing standards, so custom fabrication is often necessary.

Before
AfterChimney Cap & Crown in Boston
Chimney cap and crown work in Boston addresses a specific coastal climate failure mode: salt air and freeze-thaw cycling destroy mortar crowns faster than almost anywhere in New England. On triple-deckers in Dorchester and Jamaica Plain, we regularly find crowns completely disintegrated while the stainless cap above looks fine, because the crown bears the brunt of saturation and expansion. Our Chimney Cap & Crown service starts with camera inspection to determine whether moisture damage has reached the flue liner below.
Crown Repair
Signs you need it
Chunks of mortar missing from the crown, visible cracks that widen after winter, or water staining on interior chimney faces in upper-floor units.
What it costs in Boston
Crown repair runs $450-$900 in Boston, with triple-decker access complications sometimes adding $150-$300 for scaffolding or ladder work.
How we do it
We grind out deteriorated mortar to sound substrate, apply bonding agent, and pour new crown mix sloped 1/4 inch per foot to shed water, with a documented photo record before and after per Haven Standard Clause 4.
Crown Coating
Signs you need it
Hairline cracks across the crown surface with no spalling yet, or minor surface erosion that hasn’t compromised structural integrity.
What it costs in Boston
Crown coating costs $350-$650 in Boston, typically preventive maintenance on crowns under 15 years old with early weathering.
How we do it
We clean and prime the crown, then apply a flexible elastomeric coating rated for freeze-thaw cycling, with thickness verification photos included in your documented record.
What Chimney Cap & Crown Costs in Boston
| Item | Typical range in Boston |
|---|---|
| Crown repair | $450 - $900 |
| Crown coating | $350 - $650 |
| Cap replacement (single flue) | $200 - $450 |
Can a damaged crown cause leaks into my neighbor’s unit?
Yes, especially in triple-deckers where one chimney serves multiple units. Water entering a compromised crown can travel down the chimney structure and exit through any available opening, including into adjacent flues or wall cavities. We map moisture paths with the camera inspection and document which units are affected before any work begins.
How long does a crown repair last in Boston’s climate?
A properly poured crown with correct slope and overhang lasts 15-25 years even with Boston’s freeze-thaw cycling. Crown coating extends an existing crown’s life by 5-10 years but requires reapplication. We specify expected service life in writing with every quote.
Chimney Liner & Rebuild in Boston
Chimney liner and rebuild work in Boston is often triggered by what we find during routine cleaning in century-old masonry: no liner at all, or clay tile cracked from decades of thermal shock. In Back Bay brownstones with party-wall chimneys, liner replacement gets complicated fast, the flue you use may be structurally dependent on your neighbor’s chimney mass, and separating the two requires engineering review. Our Chimney Liner & Rebuild service includes structural assessment before any liner pull.
Stainless Steel Liner
Signs you need it
Clay tile chunks in the firebox, visible gaps in the flue wall on camera inspection, or a home inspector flagged an unlined chimney in a purchase report.
What it costs in Boston
Stainless steel liner installation runs $2,800-$4,500 in Boston, with party-wall chimneys in historic districts sometimes requiring additional structural assessment.
How we do it
We measure the flue precisely, order custom-cut 316Ti stainless segments, lower them with a winch and connect with sealed joints, then pressure-test and document with camera footage.
Partial Rebuild
Signs you need it
Significant spalling on one face of the chimney, a leaning stack above the roofline, or mortar joints eroded to finger-depth across multiple courses.
What it costs in Boston
Partial rebuilds range $3,500-$7,500 in Boston depending on height, scaffolding requirements, and whether the work affects a party wall requiring legal coordination.
How we do it
We dismantle to sound masonry, salvage usable brick where possible, rebuild with matching lime-based mortar appropriate for historic masonry, and photograph every course for the documented record.
What Chimney Liner & Rebuild Costs in Boston
| Item | Typical range in Boston |
|---|---|
| Stainless steel liner | $2,800 - $4,500 |
| Partial rebuild | $3,500 - $7,500 |
| Full chimney rebuild | $8,000 - $15,000 |
Do I need a permit for liner replacement in Boston?
Yes, the City of Boston requires a permit for any liner installation or chimney rebuild affecting structural elements. We pull permits as part of our standard process and include the permit number in your written scope. Historic district properties may need additional Boston Landmarks Commission review.
Can you line a flue in a triple-decker without accessing my neighbor’s unit?
Usually yes, if the flue is properly separated and the liner diameter fits the existing clay tile space. If camera inspection reveals shared flue space or missing separation, we document the condition and coordinate with all affected parties before proceeding, with written scope and price for each unit.

FAQs About Chimney Cleaning in Boston
We coordinate directly with property managers or condo associations and document which flue serves which unit during our camera inspection. Each unit receives its own written scope and price. We do not require all parties to agree before inspecting, but repair work on shared structural elements needs documented approval from all affected owners.
Boston does not mandate chimney inspection at closing, but most lenders and insurers in Massachusetts require documentation of chimney condition for homes with active fireplaces. Our NFPA 211 Level 2 inspection with photo record satisfies this requirement and is delivered as a stamped report within 24 hours of service.
Work on visible exterior elements in Boston Landmarks Commission districts requires a Certificate of Appropriateness. We identify historic district requirements during scheduling and include permit assistance in our standard process. Interior liner work typically does not require LBC review unless it affects exterior appearance.

What Boston Customers Say
"They ran a camera down the flue and showed me the cracked tiles on a screen. The previous company had swept it twice and never mentioned it."
- Gregory F."They told me the flue was fine and I did not need a liner. Charged me for the inspection and nothing else. That is why I have called them twice since."
- Hal M."We were buying the house and needed a real inspection. The report had photographs, the standard it was done to, and a clear repair figure. The seller paid for the repair."
