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 Services in Somerville, MA
A professional chimney cleaning in Somerville typically costs between $189 and $329 for a standard sweep and Level-1 inspection, with most appointments completed in a single visit. Triple-decker flue systems, which dominate Somerville’s housing stock, require additional verification time and run toward the higher end of that range. We’re Hearthstone Chimney Co., and we’ve been answering calls with a live person, 24 hours a day, for over 42 years. Our crews serve Somerville from our Boston office, and we know the difference between a Winter Hill triple-decker stack and a Davis Square Victorian chimney because we’ve cleaned both, dozens of times.

Why Somerville Homeowners Choose Hearthstone Chimney Co.
Somerville homeowners don’t call us because we’re flashy. They call because their neighbor on Highland Avenue did, or because their property manager in East Somerville finally found a sweep who understands triple-decker access logistics. We’ve built our reputation one flue at a time, and we document every inspection with photos you can see and a plain-English verdict you can understand.
Our technicians are background-checked and uniformed, and most jobs finish in a single visit. The price we quote is the price on the invoice. No surprises, no arguing, no paperwork chase if something needs correction. Our 90-Day Done Right Promise means exactly that: if it’s not right, we come back and make it right, in writing, no arguing. That’s the Keystone Standard we’ve operated under since 1984.
We serve homeowners in Winter Hill, Davis Square, East Somerville, and throughout the city. Whether you own your triple-decker outright or you’re a long-term tenant whose landlord finally authorized maintenance, we coordinate access respectfully and work efficiently. Calls come through to a live person, not a voicemail tree, every hour of every day.
Chimney Cleaning Services We Offer in Somerville
Chimney Cleaning & Sweep
Our standard sweep removes creosote, soot, and debris from your flue using professional-grade brushes and vacuums. In Somerville’s triple-deckers, we verify flue identity before we begin, ensuring we’re cleaning the correct channel and checking separation integrity between units. Learn more about our Chimney Cleaning & Sweep in Somerville.
Chimney Repair
Freeze-thaw damage hits Somerville’s tall, tightly packed chimney stacks harder than suburban single-flue systems. We repoint mortar, rebuild crowns, and replace damaged brick using materials rated for New England’s cycling weather. Most repairs are documented with before-and-after photos. Learn more about our Chimney Repair in Somerville.
Fireplace Services
Gas insert installations, fireplace troubleshooting, and combustion-efficiency checks for Somerville’s converted heating systems. We frequently encounter original coal-era fireboxes now serving gas appliances, and we know how to evaluate whether your setup meets modern safety standards. Learn more about our Fireplace Services in Somerville.
Chimney Cap & Crown Installation
A proper cap keeps Somerville’s squirrels, raccoons, and driving rain out of your flue. We install stainless steel and copper caps from Gelco and Copperfield, sized precisely for multi-flue triple-decker stacks or single-flue Victorian chimneys. Crown repairs use HeatShield or traditional mortar depending on damage extent.
Chimney Liner & Rebuild
Oversized original flues, common in Somerville’s converted coal-to-oil-to-gas systems, often need stainless steel relining to properly vent modern appliances. We install DuraFlex liners sized to your appliance’s BTU output, not the original coal-era dimensions. Full rebuilds use matching brick and proper crown pitch to shed water.
Neighborhoods We Serve in Somerville
We work across Somerville’s distinct neighborhoods, each with its own chimney character. Response time is typically same-week for standard bookings, with dispatch coordinated from our Boston office.
- Winter Hill - Dense triple-decker blocks where flue-identity verification is essential
- Davis Square - Mixed Victorian singles and converted multifamilies with varied flue configurations
- East Somerville - Older stacks with undocumented modifications from previous owners
- Union Square - Historic commercial-residential buildings with complex access
- Teele Square - Residential triple-deckers with shared-wall chimney structures
Why Somerville’s Climate & Housing Affect Chimney Cleaning
Somerville sits squarely in the New England freeze-thaw belt, and that matters more here than in most Boston suburbs. Dozens of freeze-thaw cycles each winter relentlessly open mortar joints and crack brick on chimney crowns, especially on the tall, tightly packed triple-decker stacks that get minimal sun exposure between buildings. The long heating season, roughly October through April, means these compromised systems work harder, longer, with more condensation cycling through oversized original flues.
Those flues were designed for coal. When Somerville’s housing stock converted first to oil, then to natural gas, the high-heat draft requirements dropped dramatically. A flue built to handle 1200°F coal exhaust now carries 300°F gas appliance venting. That temperature mismatch causes accelerated condensation on masonry surfaces, flue-liner spalling, and creosote stratification in any remaining wood-burning flues. Annual inspection isn’t an upsell here. It’s a genuine safety necessity.
The triple-decker concentration creates a specific hazard we see regularly in East Somerville and Winter Hill. A previous owner caps a middle-floor flue without documenting it. Years later, a third-floor tenant lights a gas fireplace insert, and smoke traces down through a cracked common flue wall into the second-floor unit. Confirming flue identity and separation before any cleaning is standard procedure for us. In a single-family suburban neighborhood, it wouldn’t be.

FAQs About Chimney Cleaning in Somerville
A standard chimney sweep with Level-1 inspection in Somerville runs $189 to $249 for a single-flue system, while triple-decker multifamily stacks typically range $249 to $329 due to flue-identity verification requirements. Heavy creosote buildup or glaze removal adds $75 to $150. Call (857) 392-4709 for an exact quote - estimates are free.
The National Fire Protection Association recommends annual inspection for all chimney systems, and in Somerville’s freeze-thaw climate with a seven-month heating season, that guideline is a minimum. Wood-burning flues should be swept when creosote reaches 1/8 inch thickness, typically annually with regular use. Gas flues need inspection for condensation damage and liner integrity yearly, even though they produce minimal soot. Call (857) 392-4709 to schedule - we’ll advise whether your usage pattern warrants more frequent attention.
Not always. We recommend liner replacement only when camera inspection shows visible damage - cracks, gaps, or deterioration we can photograph and show you - or when your appliance’s venting requirements mismatch the existing flue dimensions. Many Somerville chimneys have oversized original flues from coal conversions that now vent gas appliances poorly; a properly sized stainless steel liner from DuraFlex often corrects this. If the existing system is sound, we’ll say so plainly. Nothing is recommended without camera evidence you can see for yourself. Call (857) 392-4709 for a Level-2 inspection.
Skipped maintenance leads to creosote accumulation in wood-burning systems, which is combustible and the leading cause of chimney fires. In Somerville’s gas-converted triple-deckers, the more common risk is carbon monoxide intrusion through cracked flue walls or failed mortar joints, especially after freeze-thaw damage. A blocked or damaged flue can also cause dangerous backdrafting into living spaces. Annual inspection catches these conditions before they become emergencies. Call (857) 392-4709 to book - the seasonal tune-up is $89.
Somerville’s triple-deckers typically contain three or four separate flues inside one shared brick stack, and previous owners often modified these without documentation. A sweep here must verify which flue serves which unit, confirm separation integrity between flues, and check that a cracked liner in one apartment isn’t creating a carbon monoxide pathway to neighbors above or below. This verification step is standard for us and simply doesn’t exist in single-family work. Our Level-2 camera inspection documents everything with photos and a plain-English verdict. Call (857) 392-4709 to schedule.

- Ryan Hoffman"Swept it, capped it, and fitted a proper damper. The downdraft smell we had lived with every summer is gone."
