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 working in Somerville long enough to know that a “routine chimney sweep” here is rarely routine. The city’s extraordinary density of late-19th and early-20th century triple-deckers means most chimney stacks serve multiple tenants under one roof, with flues that have been modified, abandoned, or simply forgotten across decades of heating-system changes. Our Chimney Cleaning & Sweep team treats every Somerville job as a stack audit, not a quick brush-and-vacuum. We serve neighborhoods from Winter Hill to Davis Square to Union Square, and we understand how Somerville’s harsh freeze-thaw cycles - temperatures repeatedly crossing 32°F through winter and early spring - punish the mortar joints on these tall, exposed chimney stacks.
Why Hearthstone Chimney Co. Is Somerville’s Preferred Chimney Cleaning & Sweep Company
We’ve answered the phone with a live person, 24 hours a day, 7 days a week, for over 42 years. No voicemail, no callback queue, no app. When a Somerville landlord calls at 6 a.m. because a tenant’s CO detector chirped overnight, a real person picks up and books the inspection.
Our technicians are background-checked, uniformed, and trained to document every inspection with photos and a plain-English verdict. In Somerville’s triple-decker market, that documentation matters. A landlord managing three units needs to know which flue serves which apartment, which were capped when baseboard heat went in, and whether the abandoned flue is channeling moisture and cold air into the masonry surrounding the active one. We deliver a photo report that shows all of it.
Every job is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we make it right. We’ve been serving Somerville and surrounding communities since 1984, and we plan to be here in thirty more years. That changes how you treat every customer.
Our Chimney Cleaning & Sweep Services in Somerville
Level 1 Inspection
A Level 1 inspection is a visual examination of the readily accessible portions of your chimney structure and flue. For a Somerville single-family or a top-floor triple-decker unit with no heating-system changes in the past year, this may suffice. We check for obstructions, creosote buildup, and basic structural soundness. The inspection takes 45 minutes to an hour, and we include digital photos of anything worth noting. Cost in Somerville: $150-$220.

Level 2 Inspection
This is what most Somerville chimneys actually need. A Level 2 inspection includes everything in Level 1, plus a camera scan of the entire flue interior and examination of attics, crawl spaces, and other accessible areas. In Somerville’s triple-deckers, this is where we find the real problems: bare-brick coal-era flues with no liner insert, abandoned flues left open to the weather, and freeze-thaw damage to mortar joints that a visual inspection from the fireplace simply cannot catch.
Our camera inspection ends with photos you can see and a plain-English verdict. No engineering jargon, no scare tactics. Just what we found, what it means for draft and safety, and what work can wait versus what cannot. Level 2 inspection in Somerville: $250-$450 depending on stack height and number of flues.

Creosote Removal
Creosote forms in three stages. First-degree is flaky soot, easily brushed. Second-degree is crunchy chips, common with dry firewood and good draft. Third-degree is glazed, tar-like, and highly combustible - the stuff of chimney fires. In Somerville, we see third-degree creosote most often in triple-deckers where poor draft from an adjacent abandoned flue has cooled the flue gases below condensation temperature. The flue runs too cold, and creosote plates onto the brick like varnish.
We remove creosote with professional-grade brushes, chain whips, and chemical treatments where glazing is severe. For third-degree buildup, we may recommend a second sweep after a chemical treatment cycle. Standard creosote removal in Somerville: $180-$280. Severe third-degree cases: $320-$480.

Soot Removal and Annual Sweep
An annual sweep removes soot, light creosote, and any obstructions before heating season begins. For Somerville homeowners who burn wood regularly - even just weekends - this is the maintenance that prevents expensive problems. We recommend booking in late summer or early fall, before the October rush. Spring is also smart for triple-decker landlords who want to assess winter damage while it’s fresh.
Our annual sweep includes a basic inspection, flue brushing, smoke chamber and firebox cleaning, and debris removal. We leave the work area cleaner than we found it. Annual sweep in Somerville: $180-$260.

Common Chimney Cleaning & Sweep Problems We See in Somerville Homes
- Abandoned flues channeling moisture into active masonry. In Somerville triple-deckers, a flue capped when a unit converted to gas baseboard often isn’t capped properly - or at all. Cold air, rain, and squirrel nests enter the dead flue and saturate the brick surrounding your active flue. Your “clean” flue still drafts poorly because the masonry is damp and cold.
- Bare-brick coal-era flues with no liner insert. Many Somerville triple-deckers were built between 1885 and 1920 with flues sized for coal stoves. When oil or gas conversions happened decades later, proper clay liner inserts were often skipped. The result is an oversized, unlined flue that drafts poorly and allows creosote to condense on cool brick.
- Spalling brick and failed crowns from freeze-thaw damage. Somerville’s winter temperatures repeatedly cross 32°F, and each cycle forces water in mortar joints to expand and contract. By spring, the upper sections of tall triple-decker stacks show measurable new damage. Spring inspection catches this before autumn rains accelerate the deterioration.
- Landlords booking flat-price sweeps without stack audit scope. A phone quote for “one flue, one sweep” sounds reasonable until the technician arrives and finds three flues in a shared stack, two abandoned, with bare brick and no liners. The real work - the inspection and documentation that actually protects tenants - was never in the agreed scope.

FAQs - Chimney Cleaning & Sweep in Somerville
Once a year if any unit burns wood, and every two years minimum for gas or oil flues that share a stack with active wood-burning units. In Somerville’s triple-deckers, the shared masonry means one neglected flue compromises the others - so the inspection frequency should match the highest-risk use in the stack, not just your own unit. Call (857) 754-5607 and we’ll assess your specific stack.
Because heating conversions happened across decades, often without permits or documentation, and previous owners rarely left records. A unit switched to forced hot water baseboard in 1987; the flue was “capped” with a piece of sheet metal and forgotten. Our Level 2 camera inspection maps every flue, identifies what it serves (if anything), and documents which are active, capped, or abandoned open. You’ll have photos and a written report for your records.
Level 1 is visual, accessible areas only. Level 2 adds a camera scan of the full flue interior and examination of attics, basements, and other accessible spaces. For most Somerville triple-deckers - especially pre-war buildings with any heating-system changes - Level 2 is the appropriate standard. The camera finds what eyes cannot: cracked flue tiles, missing mortar, animal nests, and unlined bare brick that a Level 1 would miss entirely.
Yes, directly. In Somerville’s shared triple-decker stacks, an abandoned or poorly capped flue in your neighbor’s unit becomes a cold air intake that drops the temperature of the entire masonry mass. Your flue runs cooler, draft weakens, and creosote condenses more heavily. Moisture from their dead flue migrates through porous brick into your flue’s surround. This is why we audit the full stack, not just “your” flue.
Not reliably. Third-degree creosote is glazed, shiny, and tar-like - but it’s inside the flue, not visible from the firebox. Warning signs include reduced draft, a smoky odor when the fireplace is not in use, and black, oily drips in the firebox. But first- and second-degree creosote can produce similar symptoms. Only a camera inspection confirms what you’re dealing with. If you suspect heavy buildup, schedule a Level 2 inspection before lighting another fire. Call (857) 754-5607 - estimates are free.
