Fast, Reliable Chimney Cleaning & Sweep Across Cambridge
Chimney cleaning and sweeping in Cambridge, MA typically costs $189-$349 for a standard Level 1 sweep with inspection, and most appointments are completed in a single visit within 24-48 hours of your call. If you’re smelling smoke inside your unit, hearing debris fall down the flue, or simply can’t remember the last time your chimney was looked at, you’re dealing with conditions we see weekly in Cambridge’s older housing stock.
We’ve been answering calls from Cambridge homeowners and landlords since 1984. Our technicians know the triple-deckers of East Cambridge, the Victorian piles along Brattle Street, and the converted apartments near Central Square. Russell Haines built this company on the principle that a chimney job done right shouldn’t need to be redone, and that starts with understanding what Cambridge’s buildings actually are. Call (844) 803-1545 and you’ll reach a live person, any hour, who can book you for tomorrow or next week - your choice.
Why Hearthstone Chimney Co. Is Cambridge’s Preferred Chimney Cleaning & Sweep Company
Cambridge isn’t generic territory for us. We’ve worked on chimney stacks in North Cambridge where four flues serve four different households, each with its own heating history and its own set of problems. That kind of density and complexity takes more than a brush and a vacuum. It takes a technician who can read a chimney the way a good mechanic reads an engine.
Our customers in Cambridge mention the same things in their feedback: we show up when we say, we explain what we found in plain English, and we leave photos they can actually understand. The 90-Day Done Right Promise isn’t a slogan here - it’s in writing on every job, no arguing, no paperwork chase. If something isn’t right, we come back and make it right. That’s been our standard for over 42 years.
Response time matters in Cambridge because heating season starts early and ends late, with damp cold settling in off the Charles River from October through April. We keep our schedule flexible for Cambridge calls, and most sweeps are completed in a single visit with no-hassle upfront pricing. The number on your estimate is the number on your invoice.
Our background-checked, uniformed technicians carry professional-grade equipment from DuraFlex, HeatShield, and Copperfield - no builder-grade substitutes - and they’re trained to spot the specific failure patterns that Cambridge’s late-Victorian and Edwardian chimneys develop. When we find something that needs more than a cleaning, we also handle Chimney Repair in Cambridge and Fireplace Services in Cambridge, so you’re not calling a second contractor.
Our Chimney Cleaning & Sweep Services in Cambridge
Level 1 Inspection
A Level 1 inspection is the annual baseline for any Cambridge chimney that’s been in continuous use without changes to the appliance or fuel type. We examine the readily accessible portions of your chimney structure, flue, and connections, looking for creosote buildup, obstructions, and basic structural integrity. In Cambridge’s triple-deckers, this often means working from the appliance up through the accessible flue length, noting any signs of cross-flue leakage or deteriorating mortar that the building’s shared stack structure can hide. A Level 1 inspection with sweep in Cambridge runs $189-$249.
Level 2 Inspection
Level 2 is what Cambridge homeowners need when something has changed - a new insert, a switch from oil to gas, a chimney fire, or the purchase of an older home. This is where our camera inspection comes in. We run a high-resolution camera the full length of your flue, documenting every crack, gap, and glaze deposit with photos you can see and a plain-English verdict you can understand. In Cambridge’s housing stock, we almost always find original terracotta liner tiles cracked from repeated fuel-type transitions and thermal cycling. The camera doesn’t lie, and we don’t speculate. Level 2 inspection with documentation in Cambridge runs $279-$349.
Creosote Removal
Creosote is the real enemy in any wood-burning system, and Cambridge has plenty of them - often inserts added by tenants or prior owners without proper permits or liner upgrades. Stage 1 creosote brushes off. Stage 2 requires more aggressive mechanical cleaning. Stage 3, the glazed tar-like deposit, needs specialized removal and sometimes chemical treatment. Cambridge’s damp winters accelerate creosote formation because wet wood and incomplete combustion are more common when fuel sits in humid basements. We assess what we’re dealing with before we quote, and we remove it completely, not just “better than it was.” Creosote removal as a standalone service in Cambridge runs $220-$340 depending on stage and accessibility.
Soot Removal & Annual Sweep
Gas and oil systems produce soot, not creosote, but that soot still narrows your flue, corrodes metal components, and can block proper draft. In Cambridge’s converted multi-family buildings, we regularly find flues serving modern high-efficiency gas furnaces that were never properly resized from their original coal or oil dimensions. The soot accumulates in the oversized flue, and the draft never establishes correctly. Our annual sweep service removes all combustible deposits, checks for proper clearances, and verifies that your flue is the right size for what it’s venting. Annual sweep with basic inspection in Cambridge runs $189-$269.
Our Chimney Cleaning & Sweep team is equipped to handle all four of these services on every visit, so we don’t need to reschedule if your inspection reveals something that needs immediate attention.

Trusted Brands We Service in Cambridge
We stock and install professional-grade materials from Famco, Copperfield, and DuraFlex - brands that hold up in Cambridge’s demanding conditions, not hardware-store substitutes that fail in two seasons. Famco caps and dampers resist the salt-air corrosion that comes with proximity to Boston Harbor. Copperfield carries the full range of flue brushes and rods we need for Cambridge’s often-oversized historic flues. DuraFlex liners handle the thermal expansion that Cambridge’s freeze-thaw cycles demand. Because we keep common sizes and fittings on our trucks, most Cambridge jobs don’t wait for parts. If your chimney needs a liner, a cap, or a crown repair while we’re there for your sweep, we can often complete it that same visit.
Common Chimney Cleaning & Sweep Problems We See in Cambridge Homes
- Abandoned flues open to active ones. In East Cambridge triple-deckers, it’s common to find a single four-flue stack where one flue serves an active gas furnace, another serves a tenant’s wood-burning insert added without a permit, and one or two are capped but not sealed. Carbon monoxide and smoke can cross between units, a scenario Cambridge’s rental-inspection enforcement increasingly flags during landlord certificate-of-occupancy renewals. We identify these pathways and recommend proper sealing.
- Cracked terracotta liners from fuel conversion history. Cambridge’s chimneys were built for coal, converted to oil, then converted again to gas - each transition stressing liner tiles that were never designed for the temperature swings of modern appliances. Our camera inspections find these cracks before they become hazardous.
- Deteriorated chimney crowns and lime-mortar joints. Cambridge’s damp, cold winters and freeze-thaw cycling off the Charles River destroy pre-1940 masonry. We inspect crowns and flashing as part of every sweep, because a cracked crown lets water in, and water in a freeze-thaw cycle destroys chimneys from the top down.
- Improperly sized flues for modern appliances. A high-efficiency gas furnace venting into a flue built for a coal boiler will never draft correctly. The result is soot accumulation, moisture problems, and potential carbon monoxide spillage. We measure, we document, and we tell you straight if your flue needs relining.
