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.

Somerville homeowners with triple-decker chimneys face a problem most sweep companies outside eastern Massachusetts barely understand: one masonry stack serving multiple units, often with flues converted haphazardly from coal to oil to gas over a century, where one neglected flue threatens the safety of the whole building. A proper chimney cleaning here means auditing every flue in that shared stack, not just the one with the active fireplace. Hearthstone Chimney Co. has been answering calls with a live person, 24 hours a day, for over 42 years, and our crews work Somerville weekly - from Winter Hill to Union Square, from Davis Square over to East Somerville along Broadway. Call (857) 754-5607 and you’ll reach a real person who can book your inspection or answer questions about what your particular stack needs.

Why Somerville Homeowners Choose Hearthstone Chimney Co.
We’ve swept chimneys on Pearl Street, replaced crowns on Highland Avenue, and diagnosed draft failures in Winter Hill triple-deckers where the landlord didn’t know flue number three was still open to the sky. Somerville’s housing stock demands a sweep who understands multi-tenant masonry stacks, not a technician trained on single-family suburban flues.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict - documented like an engineer, explained like a craftsman. You’ll know exactly which flues are active, which are abandoned, and whether that abandoned flue is channeling cold air and moisture against the liner protecting your unit. Nothing is recommended without camera evidence, and we’ll tell you plainly when work can safely wait until next season.
The 90-Day Done Right Promise covers every job in writing with no arguing. If it’s not right, we come back. That’s the Keystone Standard: Krafted right, Every time, Your home first, Standing behind it. Background-checked, uniformed technicians complete most jobs in a single visit, with no-hassle upfront pricing - the number on the estimate is the number on the invoice.
Dispatch and scheduling are coordinated from our Boston office, but crews serve Somerville locally and carry the professional-grade materials this market needs: DuraFlex liners, HeatShield cerfractory resurfacing, Gelco and Famco caps and fittings. We’ve built our reputation on being the company that’s still here when you call back in five years - because we plan to be in this region in thirty more.
Chimney Cleaning Services We Offer in Somerville
Chimney Cleaning & Sweep
Our Chimney Cleaning & Sweep in Somerville service removes creosote buildup, obstructions, and debris from flues serving wood-burning fireplaces, gas inserts, and heating appliances.

Learn more about our Chimney Cleaning & Sweep in Somerville.
Chimney Repair
Freeze-thaw damage to Somerville’s tall, narrow chimney stacks shows up as spalling brick, deteriorated mortar joints, and failed crowns - especially on the exposed upper sections above the roofline. Our Chimney Repair in Somerville addresses these issues with materials rated for New England’s cycling temperatures. Learn more about our Chimney Repair in Somerville.
Fireplace Services
From damper adjustment to firebox refractory repair, our Fireplace Services in Somerville keep hearths functional and safe in units where the fireplace may be the original 1890s construction, retrofitted with a modern insert, or converted to gas. We inspect the entire system, not just the visible hearth. Learn more about our Fireplace Services in Somerville.
Chimney Cap & Crown Installation
A failed crown on a Somerville triple-decker lets water straight into the masonry core, accelerating freeze-thaw damage and risking flue liner deterioration in all connected units. We install Gelco and Famco caps with properly poured or repaired crowns, sized for multi-flue stacks and built to shed water in driving northeast storms.
Chimney Liner & Rebuild
Many Somerville flues were never lined when coal stoves gave way to oil or gas, leaving oversized bare-brick passages that condense acidic moisture and fail to maintain proper draft. We install DuraFlex stainless steel liners and, when necessary, perform partial or full rebuilds using materials matched to the original construction - with photos and a plain-English verdict before any work begins.
Neighborhoods We Serve in Somerville
Our crews know the difference between a Winter Hill triple-decker with original coal-era flues and a newer Davis Square condo conversion with a factory-built chimney system. We serve these Somerville neighborhoods regularly:
- Winter Hill - dense triple-decker stock with shared stacks and complex landlord-tenant coordination
- Davis Square - mixed pre-war and converted residential, many with original masonry fireplaces now serving gas inserts
- Union Square - industrial-era buildings with tall, exposed chimney stacks vulnerable to freeze-thaw damage
- East Somerville - Broadway corridor triple-deckers with some of the oldest unlined flues in the city
- Teele Square - residential blocks where spring inspection requests peak after each hard winter
Most appointments are available within a week during peak season; call (857) 754-5607 to check current availability.
Why Somerville’s Climate & Housing Affect Chimney Cleaning
Somerville’s extraordinary concentration of triple-deckers - three-unit stacked residences built largely between 1885 and 1920 - creates a chimney maintenance problem almost unique in American cities. Each building typically shares a single tall, narrow masonry chimney stack containing two or three separate flues, originally sized for coal stoves, then converted to oil or gas over decades with no consistent standard for liner installation. A sweep who treats your flue as an isolated system misses the critical interactions: an abandoned flue left open to the sky draws cold air down through the masonry, creating thermal bridging that chills the active flue beside it, accelerating creosote condensation and reducing draft efficiency.
The city’s position in the Greater Boston freeze-thaw zone makes this worse. Temperatures cross 32°F repeatedly through winter and early spring, and each cycle forces moisture in compromised mortar joints to expand and contract. By March, we’ve documented new spalling brick and crown cracks on stacks we inspected the previous fall. Spring is peak inspection season in Somerville precisely because winter inflicts measurable, visible damage that wasn’t there six months prior. Landlords managing triple-deckers often don’t know which flues are active in which units, which were capped during prior conversions, and which were simply abandoned open - a scenario where the “dead” flue channels moisture, cold air, and nesting animals directly into the masonry surrounding your active flue. Our camera inspection identifies these conditions without guesswork, and we explain what we’re seeing in plain English, with photos you can show your tenants, your insurance agent, or your own records.

FAQs About Chimney Cleaning in Somerville
A standard single-flue chimney sweep in Somerville typically runs $189 to $279, while a multi-flue triple-decker audit runs $329 to $479 because we’re inspecting and documenting every flue in the shared stack. Your exact cost depends on accessibility, creosote buildup level, and whether camera inspection is needed. Call (857) 754-5607 for a free estimate - estimates are free, and we quote upfront with no surprises on the bill.
The National Fire Protection Association recommends annual inspection for all chimneys, and sweeping whenever creosote buildup exceeds 1/8 inch. In Somerville’s triple-deckers, we often find that flues serving wood-burning appliances need sweeping every year, while properly lined gas flues may extend to every two years with annual inspection. The abandoned flue in your stack - the one nobody thinks about - should be inspected at the same interval, since it affects the masonry surrounding your active flue. Call (857) 754-5607 to schedule and we’ll recommend the right interval for your specific system.
Not always. Many Somerville flues are unlined bare brick from the coal era, and some can continue functioning safely with proper maintenance. We recommend liner installation when camera inspection shows deteriorated mortar joints, flue gas leakage into adjacent flues, or sizing mismatched to your current appliance. You’ll see the photos and hear our plain-English verdict before any recommendation. When a liner is needed, we install DuraFlex stainless steel systems sized precisely to your appliance. Call (857) 754-5607 for a Level-2 inspection and second opinion - estimates are free.
Skipped maintenance leads to creosote accumulation, which is combustible and the leading cause of chimney fires. In Somerville’s multi-flue stacks, the risk compounds: a fire in one flue can crack the thin masonry partition into an adjacent flue, or damage the exterior stack structure shared by all units. Carbon monoxide backdrafting is the other hazard, especially in oversized unlined flues that fail to maintain proper draft. These are real risks with specific consequences, not scare tactics. The good news is they’re entirely preventable with annual inspection and cleaning as needed. Call (857) 754-5607 to get back on schedule.
Yes, and we do this regularly in Somerville’s triple-decker market. We coordinate directly with property managers or landlords, document which flues serve which units, and provide a single report covering the entire stack. Tenants don’t need to be present if access is arranged, though we prefer to notify all occupants when we’re working on a shared system. Our background-checked, uniformed technicians carry identification and explain their findings to whoever is on site. Call (857) 754-5607 to discuss scheduling for your building - we’ll make it straightforward.

What Somerville Customers Say

- Xavier Freeman"Second property I have had them at. Both times the tech showed me photos from inside the flue before quoting anything."
- Ryan Hoffman"The cap keeps the birds out now, which after two springs of scratching noises above the bedroom is worth every penny."
