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, MA typically runs $180 – $340 for the first flue, and most homes here have more than one flue in a shared stack, so the total depends on what you actually need swept. We work throughout Somerville: Spring Hill, Winter Hill, Davis Square, Union Square, Powder House Square, East Somerville, and the streets around Tufts off Broadway. Our crews know the triple-deckers, the two-families, the converted condos, and the older single-families that fill this city. If you want a flat price agreed before we book, with a camera inspection and photo report included, call (830) 251-4560.
Why Flint Chimney Sweep Is Somerville’s Preferred Chimney Sweep Company
Somerville homeowners have a specific problem that most chimney companies from outside the city don’t fully grasp: one masonry stack often carries two or three separate flues. We see it every week on streets like Highland Ave, Cedar Street, and Summer Street. A landlord or condo owner calls us in for a Chimney Sweep, and what we find is a triple-decker where the first-floor unit’s flue got swept years ago but the second-floor flue hasn’t been touched since the last tenant moved out. That matters. You can’t sweep one flue in a shared stack and call the whole chimney clean. Our teams work across the Somerville area with this stacked condition in mind from the first call.
Flint Chimney Sweep has operated since 2002 as part of the Garrison Partners family of independently owned chimney service companies. Our technicians are background-checked and uniformed. You know who’s walking through your door. Every job gets a written price before any work starts, and every repair carries a 365-Day Done Right Promise, a written guarantee valid for one full year from the service date. If a covered repair fails inside that year, we return at no charge. That’s not a sales pitch. It’s how we’ve run under The Garrison Standard since the beginning.
We answer the phone with a live person 24 hours a day, seven days a week. No voicemail trees, no callback forms, no waiting until Monday to hear back about a chimney that’s making your living room smell like a campfire. When you call (830) 251-4560, you get a person who can schedule a sweep for Somerville and tell you exactly what the visit will include.
Chimney Sweep Certified in Somerville
Chimney Sweep Certified in Somerville means we don’t just run a brush up the flue and call it done. Our process includes a full visual inspection of the firebox, damper, smoke chamber, and accessible flue, followed by a mechanical sweeping of the flue that serves that specific fireplace or stove, and a camera inspection up the cleaned flue to confirm the creosote is gone and the liner is sound. A homeowner in Somerville should have this done when creosote reaches first-degree thickness (a thin, flaky, tar-like film you can scrape with a fingernail), when the fire isn’t drafting well, when you smell smoke after a fire, or when it’s been more than a year since the last sweep.
In a Somerville triple-decker, one address often means two or three fireplaces, each on its own flue inside the same brick stack. So no, one sweep does not cover the whole house. Each flue is a separate job, and each needs its own inspection. A standard sweep for one flue in Somerville runs $180 – $340. The second and third flues are priced the same way, and you’ll see those numbers in writing before any work begins.
Creosote and Soot Removal
Creosote is the flammable residue that condenses from wood smoke as it cools against the flue walls. Left alone, it builds in layers; first-degree is loose and flaky, second-degree is thick and tar-like, third-degree is a hard glaze that typically requires rotary cleaning or chemical treatment, not a standard brush. Soot removal is simpler, but both jobs require the flue to be swept and then visually confirmed with a camera. We don’t trust a guess, and in a city with as many 100-year-old stacks as Somerville, guessing is what gets people hurt.
Annual Sweep and Fireplace Cleaning
The National Fire Protection Association standard (NFPA 211) says chimneys should be inspected at least once a year and swept when any appreciable creosote or soot buildup is present. Our annual sweep for Somerville homeowners includes the mechanical cleaning, the damper check, the smoke chamber inspection, and a written photo report so you walk away knowing what was found. If you burn wood regularly from October through March, a yearly sweep is the baseline, not an upsell.
Gas Fireplace Cleaning in Somerville
Gas Fireplace Cleaning in Somerville covers the vented gas logs, the glass, the burner, and the venting system, plus a check of the gas valve and connections for leaks. Many Somerville condos and converted units have gas fireplaces as the original heating source or as a supplemental one, and those fireplaces produce soot and debris inside the glass and blower housing over time. A gas fireplace cleaning in Somerville runs $150 – $250 for a standard unit, and it typically takes about an hour.
Gas fireplaces still need camera inspection of the flue or direct vent, especially in units that were converted from wood-burning fireplaces decades ago. We check that the venting path is clear, the termination cap is in place, and no birds or debris have blocked the exhaust. If the fireplace hasn’t been serviced in years, the burner ports can clog, the pilot assembly can corrode, and the logs can develop carbon buildup that shortens their life. A cleaning with us includes a written price beforehand and a photo report after.
Vented and Vent-Free Gas Logs
Vented gas logs burn with a realistic yellow flame but lose quite a bit of heat up the chimney, which is why some Somerville units have vent-free logs instead. Vent-free logs produce more heat into the room but release combustion byproducts into the living space, so they need careful burner inspection and regular cleaning to keep carbon monoxide output at safe levels. If you’re not sure which type you have, we’ll tell you during the visit and explain what kind of cleaning it needs.
Glass and Burner Service
Cloudy glass on a gas fireplace is usually a sign of mineral deposits from the combustion process, and we clean it properly rather than just wiping the surface. If the burner ports are partially clogged, the flame gets uneven and the log set gets sooty in patches. Our standard cleaning addresses both, and if we find a failed blower motor or a damaged gas valve, we’ll show you the photo evidence and put the repair on a written estimate, never a surprise invoice.
Trusted Brands We Service in Somerville
We install and work with professional-grade chimney products from Famco, Copperfield, and DuraFlex, among others. Those names matter in a city like Somerville, because the materials specified for a triple-decker shared-stack repair have to be rated for the job, not just whatever is on the truck. Our crews stock common parts locally for Somerville customers, which means less waiting when a damper plate, a cleanout door, or a chimney cap needs replacement during a routine sweep.
Common Chimney Sweep Problems We See in Somerville Homes
- Multiple flues in a single stack, treated as one chimney. A triple-decker at Winter Hill or Spring Hill often has three flues sharing one masonry stack. If only the flue tied to the fireplace in use gets swept, the other flues keep building creosote until someone finds it by accident. We sweep and inspect every flue in the stack, individually.
- Down-drafting on upper floors. In Somerville’s older two- and three-families, we see negative pressure from kitchen exhaust fans, bath fans, and tight windows pulling smoke back down the flue. A camera inspection identifies the obstruction or the damper issue, but the full fix often involves checking the whole house’s ventilation picture, not just the chimney.
- First-degree creosote buildup after one burning season. New homeowners in Somerville who buy a condo in a converted triple-decker often burn wood all winter without knowing when the flue was last swept. A single season of wet wood or low-temperature fires can leave enough creosote to require a sweep. We pull the damper and show you what’s actually there.
- Spalling in the smoke chamber hidden behind the damper. A brush goes up the flue, but the smoke chamber above the damper is where smoke lingers at the widest point of the chimney’s path. In older Somerville stacks, the mortar there can be soft or flaking. A camera inspection up the flue catches early spalling before it becomes a masonry repair, and our photo report gives you the evidence either way.
Pricing for Chimney Sweep in Somerville, MA
Here’s what you’re looking at. A standard chimney sweep for one flue in Somerville runs $180 – $340. A gas fireplace cleaning runs $150 – $250. A Level 1 inspection (visual, without disassembly) ranges $75 – $150. A Level 2 inspection (camera, no demolition, used for real estate sales, after a chimney fire, or after a major weather event) runs $175 – $350. The second and third flues in a triple-decker are priced individually, not bundled into a one-size fits all number. The exact total depends on how many flues you have, what condition they’re in, and whether any repair is needed. What it never depends on is our mood that day.

FAQs About Chimney Sweep in Somerville
Yes, we sweep both flues in the same visit, but each flue is a separate job with its own price because each flue is a separate pathway. In a typical Somerville triple-decker on Highland Ave or Central Street, one stack carries two or three flues, each with its own damper and its own creosote condition. We’ll sweep and camera-inspect each flue, then give you one written photo report covering the whole stack. Call (830) 251-4560 for an exact quote, estimates are free.
Once a year if you burn wood regularly, which means at least a couple of fires per week during the heating season. The NFPA standard says inspect annually and sweep when there’s visible buildup, but in practice, a Somerville homeowner burning wood from November through March will have first-degree creosote by spring. If you only use the fireplace occasionally, a sweep every 18 to 24 months can be enough, but the camera inspection should still happen every year. We’ll tell you plainly if your flue can safely wait, based on what the camera shows, not on a schedule.
A Level 1 inspection is a visual check of the accessible parts of the chimney, the firebox, the damper, and the flue opening. A Level 2 inspection uses a camera to see the entire flue interior, the smoke chamber, and the connection points, and it’s required when you’re buying or selling a home, after a chimney fire, after a major storm, or when you haven’t had the chimney inspected in years. In Somerville, where many homes are bought as condos or multi-unit buildings with shared stacks, we recommend a Level 2 inspection on the first service call so you have a camera-recorded baseline. After that, annual Level 1 inspections are usually enough.
Third-degree creosote is the hard, glazed tar that a standard brush can’t remove. It requires rotary cleaning heads, chemical softening agents, or both, and sometimes the liner itself is too far gone and needs replacement with a product like DuraFlex. We don’t tell you that over the phone because we haven’t seen your flue yet. What we do is camera-inspect it, show you the photos, and give you a written recommendation based on what the camera shows. If it needs rotary cleaning, you’ll see the price beforehand. If it needs a new liner, you’ll see the photos proving it.
We service both. Our Gas Fireplace Cleaning covers vented and vent-free gas logs in Somerville, including glass cleaning, burner inspection, gas valve and connection checks, and venting verification. A gas fireplace cleaning runs $150 – $250. If your gas fireplace is in a converted condo in Spring Hill or a single-family near Powder House Square, we’ll confirm the venting path is clear and the termination cap is intact before we finish the visit. Call (830) 251-4560 to schedule, and you’ll have a written price before we book.
If you’ve got a chimney in Somerville that hasn’t been inspected in more than a year, or you just bought a place and don’t know the flue’s history, call (830) 251-4560.
