Cambridge homeowners pick Dorian Chimney Co. for Arlington chimney work because we don’t just sweep, we diagnose. A clogged chimney in Cambridge’s damp winters isn’t just a mess; it’s a fire hazard. Our crews use brushes that fit your flue exactly, remove creosote down to the crown, and spot cracks or blockages before they become emergencies. No upsells, no ‘we’ll see what’s wrong’, just a clean flue and a written report. That’s why we’re the go-to for Somerville’s brick row homes and Watertown’s older colonials.
1. A chimney inspection is a structured check of your flue, liner, and chimney structure, not just a quick look down the pipe.
Cambridge homeowners often confuse a ‘sweep’ with a ‘look-see,’ but a real inspection follows the Chimney Safety Institute of America’s three levels. We start with Level 1 (basic visual check) but move to Level 2 or 3 if we spot issues like cracked masonry or rusted dampers, common in Cambridge’s older homes built before the 1950s. For example, a Somerville row house with a cast-iron liner might need a Level 2 inspection to check for corrosion from moisture.

2. Cambridge’s climate demands a chimney sweep that handles creosote like a pro, not just a ‘scrub and go’ job.
Cambridge’s wet summers and freezing winters? That’s a recipe for creosote buildup. Skip the sweep, and you’re asking for trouble. The EPA’s Burn Wise program warns that stage 3 creosote (glassy, tar-like) is a chimney fire waiting to happen, and it’s common in homes burning damp firewood. Our crews use motorized rotary brushes for stubborn buildup, then inspect the flue for soot patterns that reveal draft issues or blockages. A Watertown homeowner once told us their ‘last sweep’ left black streaks; we found a collapsed liner section they’d missed.

3. We specialize in Cambridge’s housing stock, from Back Bay brick to Arlington’s historic masonry, not generic ‘one-size-fits-all’ sweeps.
Your chimney isn’t like your neighbor’s. A Cambridge Back Bay townhouse with a clay liner needs different care than an Arlington colonial with a masonry chimney. We train our crews on local materials: how to clean a cast-iron liner without damaging it, or how to spot spalling bricks in Cambridge’s freeze-thaw cycles. For example, the chimneys along Brattle Street often have hairline cracks from foundation shifts, something a DIY sweep won’t catch.

4. No ‘hidden fees’, our Arlington chimney sweep pricing covers what it covers, period.
Some sweeps quote $120 for a ‘basic’ job, then hit you with $200 for ‘extra creosote.’ We charge $150–$250 for a full sweep in Cambridge, depending on chimney height and access, no surprises. For example, a Belmont home with a 30-foot chimney and a tight attic access will cost more upfront, but you won’t pay extra for ‘unexpected’ work. Our pricing page breaks it down by chimney type, so you know before we show up. Chimney Sweep Cost / Pricing Guide
5. We fix what we find, no ‘call someone else’ excuses.
If our inspection turns up a cracked crown, rusted damper, or missing cap (common in Cambridge’s older homes), we’ll give you a no-pressure quote for repairs. Too many sweeps send you to a ‘specialist’, then you’re stuck with a second crew, second invoice, and no warranty. We partner with licensed masons and flue repair techs in Somerville and Watertown, so we can often handle minor fixes on the spot. For example, we replaced a corroded damper for a client in Arlington during their sweep, saved them a separate service call. 7 Signs Your Cambridge Chimney Needs Emergency Repairs (And What to Do Next)

No ‘we’ll be there tomorrow’ promises. Our crews book appointments in advance, arrive on time, and leave your home cleaner than they found it. We’re licensed through the state of Massachusetts and carry full liability insurance, something DIY sweeps or fly-by-night crews often skip. Plus, we offer a 30-day warranty on our work. If your chimney isn’t clean after we leave, we’ll come back and fix it. The Ultimate Guide to Choosing a Licensed Chimney Sweep in Cambridge, MA (2024)
7. We answer the questions Cambridge homeowners actually have, not just sales pitches.
Most chimney companies regurgitate the same FAQs. We cut to the chase with answers like: - ‘My chimney smells after a sweep.’ That’s usually leftover soot or a blocked cap. We’ll check for moisture too. Cambridge’s damp air can cause mold in flues. - ‘Why does my gas fireplace flicker?’ Could be a cracked heat exchanger or a blocked flue. We’ll inspect the entire system, not just the chimney. - ‘I only burn once a week, do I still need a sweep?’ Yes. Even light use builds creosote. The NFPA’s chimney fire code the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) recommends annual sweeps for all chimneys, regardless of use.

Frequently Asked Questions
My Cambridge chimney was swept last year, but it’s still smoking when I light the fire. What’s wrong?
Smoke means poor draft, usually from creosote blocking the flue or a cracked liner. Cambridge’s older homes often have collapsed liners, our crews spot these during inspections. A quick fix might be a chimney cap, but if the liner’s damaged, you’ll need a relining. We’ve seen this in Arlington’s 19th-century homes where the original clay liners eroded.

Why does my Somerville chimney need a sweep if I only use the fireplace in winter?
Creosote starts building the moment you burn wood, even once a week. Cambridge’s humidity turns soot into sticky tar faster than you think. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends sweeping at least once a year, or more if you burn wet wood.

Black soot on your fireplace floor after a burn? That’s not supposed to happen.
No. Soot on the hearth means the sweep didn’t clean the flue properly, or your chimney has a draft issue. Cambridge’s older homes often have cracked crowns or missing caps, letting rain and debris in. We’ve seen cases where a ‘quick sweep’ left soot because they didn’t use the right brush size for the flue.

My gas fireplace in Arlington makes a hissing noise. Should I call a chimney sweep?
Yes, hissing usually means a gas leak or blocked flue. Cambridge’s older gas lines can corrode, and a clogged flue traps carbon monoxide. We inspect the entire system, not just the chimney.
