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.

We’ve been up and down Boston’s triple-deckers, brownstones, and converted condos since 2009, and the chimneys here tell a story you don’t see inland. The salt air off Boston Harbor eats metal. Freeze-thaw cycles fracture brick. And in shared buildings from Dorchester to Beacon Hill, one owner’s neglect becomes everyone’s hazard. That’s why our Chimney Sweep team treats every flue as a separate system, documents everything with photos, and gives you a written price before we start.
Why Emberly Chimney Cleaners Waltham Is Boston’s Preferred Chimney Sweep Company
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, every one with a written price agreed beforehand and a documented photo record on completion. Boston homeowners find us because they read the three-star reviews first, and they stay because we show them what we found rather than asking them to trust us.
Our Boston customers mention the same things: the text when the tech is en route, the license number on the page, the camera footage they can watch themselves. Background-checked, uniformed technicians arrive on schedule, and a live person answers the phone 24/7, not a voicemail tree.
We’re not fastest. We’re the ones who check all three flues in your triple-decker, not just the one that complained. That’s the difference between a flashlight look and an NFPA 211 Level 2 inspection.
Our Chimney Sweep Services in Boston
Level 1 Inspection
A Level 1 inspection is a visual examination of the readily accessible portions of your chimney and fireplace, required annually by NFPA 211 for chimneys in regular use. In Boston’s pre-1940 housing stock, we use this baseline check to spot the early signs of salt corrosion on caps and crowns that waterfront exposure accelerates. Most Level 1 inspections in Boston run $150-$220 when bundled with a standard sweep.
Level 2 Inspection
A Level 2 inspection includes everything in Level 1 plus a camera scan of the full flue interior, the attic, and the basement connection points. This is mandatory when you’re buying a home, changing appliances, or after any chimney fire or seismic event. In Boston, we perform Level 2 inspections on virtually every triple-decker and brownstone conversion we visit because shared flues and unlined coal-era chimneys create conditions a visual check simply cannot catch. Our camera documentation became the foundation of Haven Standard Clause 4 in 2009, and we include it on every Level 2 job. Expect $280-$450 in the Boston market.
Creosote Removal
Creosote builds in stages. First-degree is flaky soot. Second-degree is crunchy chips. Third-degree is a tar glaze that brushes cannot remove and requires chemical treatment or rotary cleaning. Boston’s cool, humid coastal climate slows complete combustion in wood-burning fireplaces, accelerating creosote accumulation compared to drier inland regions. In triple-deckers where landlords only sweep the complaining unit, we’ve found third-degree glaze in adjacent flues that had gone untouched for eight years. Creosote removal in Boston ranges from $180-$320 for first- and second-degree buildup to $450-$750 for third-degree chemical treatment.
Soot Removal & Annual Sweep
A standard sweep removes soot and first-degree creosote from the firebox, smoke chamber, and flue liner using rotary brushes and HEPA vacuum containment. For Boston homeowners with gas inserts or rarely used decorative fireplaces, the annual sweep is still critical: condensation in oversized, unlined flues common to converted coal chimneys produces acidic moisture that deteriorates mortar from the inside. We see this pattern constantly in Back Bay and South End row houses. Annual sweep with basic inspection: $180-$280.

BeforeAfterTrusted Brands We Service in Boston
We source materials through Haven’s buying network to keep customer prices honest, stocking caps, liners, and repair components from Olympia Chimney, Famco, and DuraFlex for same-week installation on most Boston jobs. A stainless steel cap from Olympia Chimney outlasts galvanized steel by a decade in Boston Harbor’s salt air, and we keep the common sizes on our trucks. When a HeatShield cerfractory flue liner repair is the right fix for a degraded Boston chimney, we don’t order it, we install it.
Common Chimney Sweep Problems We See in Boston Homes
- Salt-corroded caps and flashing in waterfront neighborhoods. The salt-laden air off Boston Harbor destroys galvanized steel chimney caps in under 5 years, where inland caps last 15. We replace them with stainless steel from Olympia Chimney and inspect the crown for water intrusion damage.
- Freeze-thaw mortar fracture on single-wythe brick chimneys. Boston’s coastal climate crosses 32°F dozens of times each winter, expanding ice in mortar joints until the brick face spalls. Annual inspection catches this before structural rebuilding becomes necessary.
- Unlined or oversized flues in converted coal chimneys. Original chimneys sized for coal stoves were never relined for modern gas or oil appliances, leading to excessive condensation, poor draft, and accelerated liner deterioration. A Level 2 camera scan reveals the actual condition.
- Neglected adjacent flues in triple-deckers. Landlords address only the complaining tenant’s flue, leaving second- and third-floor units with years of accumulated creosote and creating cross-unit carbon monoxide risk structurally baked into this housing type.

FAQs - Chimney Sweep in Boston
Annually, at minimum. Boston’s coastal salt air and severe freeze-thaw cycle accelerate cap corrosion and mortar deterioration compared to inland climates, so the NFPA 211 annual standard is a floor, not a ceiling. Waterfront properties in East Boston, Charlestown, and South Boston should consider inspection every 10-12 months even with infrequent use. Call (781) 649-9326 to schedule, estimates are free.
Salt-laden air off Boston Harbor accelerates galvanic corrosion on any non-stainless metal. A galvanized cap that would last 15 years in Worcester can show failure in 4-5 years facing the harbor. We replace rusted caps with stainless steel models from Olympia Chimney and inspect the crown for water damage the failed cap allowed in. Call (781) 649-9326 for a written replacement quote.
Yes. Each flue is a separate combustion exhaust system, and creosote accumulation in one does not care about property lines. We’ve found second-degree creosote in untouched adjacent flues while the landlord only addressed the complaining unit. We were called to a triple-decker on Pleasant Street in Dorchester where exactly this had happened. Our tech found second-degree creosote in the adjacent flues and a rusted galvanized chimney cap that had failed, allowing water to spall the brick. We replaced it with a stainless steel cap from Olympia Chimney, swept all three flues, and installed a HeatShield liner in the worst one to restore draft and safety. Every flue needs its own inspection and cleaning schedule. Call (781) 649-9326 for multi-flue pricing.
Third-degree creosote is a hardened, tar-like glaze that standard brushes cannot remove. It forms when wood burns incompletely at low temperatures, and Boston’s humid coastal climate makes it more common here than in drier regions. Removal requires chemical treatment to soften the deposit, followed by rotary mechanical cleaning, typically $450-$750. A standard sweep will not touch it. If your chimney professional claims otherwise, get a second opinion. Call (781) 649-9326, free second opinions on any written estimate.
Yes, and the documentation often makes this difficult. In brownstone-to-condo conversions across Beacon Hill and the South End, condo declarations frequently leave chimney ownership ambiguous across multiple unit owners. Technicians routinely find shared chimneys where three or four separate owners share one structure, none of whom have authorized or coordinated a full multi-flue cleaning in a decade. We document each flue separately, provide individual photo records per Haven Standard Clause 4, and can present a single written scope for association approval if that helps cut through the ownership fog. Call (781) 649-9326 to discuss your building’s situation.
