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.

AfterFast, Reliable Chimney Sweep Across Somerville
A standard chimney sweep in Somerville typically runs $189 – $279 for a single flue, and most jobs are completed in under two hours. For triple-decker buildings with shared stacks, we price by the flue, not by the building, so each unit owner pays only for their own line. If you’re in Somerville and your fireplace hasn’t been touched in years, call (336) 863-3889 and Ruben Castellano’s team will give you a straight answer and a written price before any work starts.
We’ve spent years working inside Somerville’s wood-frame triple-deckers, brick rowhouses, and converted condos. That matters because a chimney in a single-family home in the suburbs and a century-old shared stack in Winter Hill are not the same job. Our crews know what to look for before anyone opens a firebox door.
Why Alcott Chimney Sweep Is Somerville’s Preferred Chimney Sweep Company
Alcott Chimney Sweep has been doing this work since 2002, and in Somerville we’ve earned a reputation for showing up when we say we will and telling homeowners the truth about what their chimney actually needs. When a Winter Hill condo owner hears “you need a full reline” from another company, they usually call us for a second opinion. Often, a camera inspection shows the flue just needs sweeping or a HeatShield repair, not a $6,000 replacement.
Every tech we send to Somerville is background-checked and identity-verified under what we call the Threshold Standard. Before the appointment, you’ll get the technician’s name and photo sent to you. When they arrive, they’ll show a photo ID badge at the door. No exceptions. If you’re home alone, or your kids are napping upstairs, you’ll know exactly who’s stepping onto your property before the truck parks.
We answer every call with a live person, day or night. If you smell smoke in your Magoun Square condo at 11 p.m., a real human picks up at (336) 863-3889 and helps you figure out whether you need immediate service or can wait until morning.
Chimney Cleaning in Somerville
Chimney cleaning in Somerville means removing creosote, the tar-like byproduct of wood combustion that builds up inside a flue and is the primary cause of chimney fires, along with soot and any blockages like bird nests or fallen brick. In a Somerville triple-decker, we clean each flue separately and document what we find with a camera, because what’s in one flue isn’t necessarily in the flue next to it.
A sweep here runs $189 – $279 per flue. We’ll give you that price in writing before starting. If you’re in a three-unit building and only your flue gets cleaned, the neighbors’ flues remain untouched, and we’ll note that on your report for the condo association.
What Gets Removed
Creosote comes in three stages: flaky, tar-like, and glazed. Glazed creosote is hard, shiny, and highly flammable, and we see it regularly in Somerville flues that went decades without service. We brush-sweep what we can and recommend professional removal for the rest.
Soot removal is part of every sweep. In flues converted from oil to gas, we also check for acidic condensation residue, which eats at clay tile liners faster than heat alone ever did.
How We See Inside The Flue
Before we recommend any repair, we run a camera down the flue and show you the footage. That’s not an upsell; it’s how we work. You’ll see the cracked tile, the missing mortar joint, or the glazed creosote with your own eyes, and then we’ll talk about what actually needs to happen.
Fireplace Cleaning in Somerville
Fireplace cleaning in Somerville is not just about the flue. We clean the firebox, the smoke chamber, the damper assembly, and the hearth area. In a 100-year-old Somerville fireplace that’s been boarded over or converted, we often find years of ash, rusted dampers, and mortar that’s crumbled into the smoke shelf.
Expect $169 – $249 for a standard fireplace cleaning when combined with a flue sweep. If your fireplace was sealed for 30 years, the first cleaning takes longer and may run toward the higher end. We’ll tell you before we begin.
Dormant Fireplaces Brought Back To Life
The Green Line Extension opened in 2022, and a wave of condo conversions followed. We’ve since cleaned dozens of fireplaces in Somerville that hadn’t been opened in 30-plus years. A first cleaning typically involves removing the old damper plate, clearing the smoke shelf, and running a camera to confirm the flue is still sound.
Gas Inserts And The Flues They Use
Many Somerville fireplaces now hold gas inserts. The flue behind them still needs regular service, which is why we offer Gas Fireplace Repair in Somerville alongside our cleanings. Cooler gas exhaust condenses inside old clay tile liners and produces acidic residue that accelerates cracking. We check the liner and the termination cap on every gas insert cleaning.
Trusted Brands We Service in Somerville
We install and service chimney sweep equipment and repair materials from brands chimney professionals actually specify: DuraFlex liner systems, HeatShield resurfacing, and Olympia chimney caps. When a Somerville triple-decker needs a partial reline or flue resurfacing, we stock those trade materials locally, which means most repairs can be scheduled within days, not weeks. Famco and Copperfield components round out the caps and dampers we keep on the truck.
Common Chimney Sweep Problems We See in Somerville Homes
Somerville’s housing stock creates a specific set of chimney failures. These are the four we encounter most often across Somerville:
- Three fuel generations in one stack. In Winter Hill and Magoun Square triple-deckers, we routinely find a single chimney where the first-floor flue once served a coal furnace, the second was later connected to an oil boiler, and the third vents a gas insert. The liner conditions and flue sizing match none of the appliances currently using them, which regularly triggers mandatory relining under Somerville’s building inspection process.
- Cracked clay tile liners from oil-to-gas conversions. Modern gas exhaust runs much cooler than oil combustion. Inside a flue sized for hot oil exhaust, that cool, acidic moisture condenses and eats through clay tile liners. We see this constantly in Somerville condos converted in the last 15 years.
- Spalling mortar opened by freeze-thaw cycles. The same freeze-thaw cycle that destroys Somerville sidewalks also works on century-old brick chimneys. Water seeps into lime mortar, freezes, expands, and pops the joint open. In a shared stack, those gaps let flue gases move between units, which is a serious CO cross-contamination risk.
- One clean flue in a three-flue stack. A caller books a sweep for their unit, and the neighbors’ flues remain untouched in the same masonry stack. Creosote buildup in a neighboring flue can still threaten everyone in the building. We document what we find for the association and offer to clean all three flues in a single visit.
Pricing for Chimney Sweep in Somerville, MA
A single-flue chimney sweep in Somerville runs $189 – $279. Adding a full fireplace cleaning brings the total to $169 – $249 for the firebox and hearth when booked with the sweep. A Level 1 inspection runs $129 – $199, and a Level 2 inspection, which includes camera work and is often required during condo sales in Somerville, typically costs $249 – $399.
What changes the price here is what we find: glazed creosote removal costs more than standard brushing, and a HeatShield repair runs less than a full reline. We give you the written price before any work begins, and no work is recommended without camera evidence you can see. Call (336) 863-3889 for a free estimate.

FAQs About Chimney Sweep in Somerville
Yes, ideally all three flues should be swept and inspected each year, because they share a single masonry stack and a fire or CO leak in one flue threatens every unit above and below it. We’ll give you a priced quote for each flue separately so the cost can be split among unit owners, and we’ll document what we find for the association. Call (336) 863-3889 and we’ll schedule all three in one visit.
Cool condensation is the likely cause. Modern gas boilers exhaust at much lower temperatures than the oil burners those flues were sized for, and that cooler exhaust causes acidic moisture to condense against the liner, which soaks the clay tile and eats at it over time. We’ll run a camera to confirm the liner condition and recommend whether a resurfacing or reline is actually needed. Estimates are free at (336) 863-3889.
NFPA 211, the national standard, says chimneys should be inspected at least once a year, and swept whenever creosote reaches 1/8 inch of buildup. In Somerville’s older triple-deckers and converted rowhouses, we recommend the same annual cadence at minimum, and more often if the flue serves a wood-burning fireplace used regularly. Book your annual check by calling (336) 863-3889.
The first cleaning involves removing the seal, inspecting the damper and smoke shelf, brushing the flue, and running a camera to confirm the liner is intact before you light a fire in it. We’ve done dozens of these reactivations in Somerville since the Green Line Extension sparked the condo wave, and we’ll show you the footage before you ever strike a match. For a first-cleaning quote, call (336) 863-3889.
Somerville’s building inspection process requires that a flue match the appliance venting into it, and in century-old triple-deckers, the original flue was almost never sized for a modern gas insert or high-efficiency boiler. If our camera confirms cracked clay tiles, missing mortar joints, or a flue that’s simply too large for the current appliance, the inspector will require a reline, and we’ll give you that news with footage you can see for yourself. Call (336) 863-3889 and we’ll walk you through what the inspector is looking for.
One honest note from the field. In a Winter Hill triple-decker off Medford Street, we found a shared masonry stack where the first-floor flue had once served a coal furnace, the second had been retrofitted for an oil boiler, and the third vented a gas insert. Our tech ran a camera down each flue and showed the homeowner live footage of third-degree creosote glazed along the second-floor flue wall and cracked clay tiles separating the flues. We brush-swept the first and third flues, applied HeatShield to the second, and documented every step for the building inspector. That’s the job, done the way it should be.
