Frequently Asked Questions - Chimney Cleaning in Boston, MA
We've been sweeping, inspecting, and repairing chimneys across Boston and the South Shore since 2014. Here are the questions we hear most often, answered straight.
Pricing & Cost FAQs
A standard chimney sweep in Boston typically runs between $180 and $280 for a single flue in good working order. Two-story homes in neighborhoods like Roslindale or West Roxbury, where roof access is trickier, sometimes land toward the higher end. We always agree to a flat price before we book, and every sweep includes a basic visual inspection. Call (857) 597-5950 for an exact quote - estimates are free.
A level-2 inspection with camera runs $350 to $500 in the Boston market, depending on the number of flues and how far we need to run the camera. This is the inspection you need when you're buying a home in Milton or Hingham, or after a chimney fire, earthquake, or major weather event. We document everything with photos you can see yourself, and we explain what needs attention now versus what can wait. Call (857) 597-5950 for an exact quote - estimates are free.
Not automatically, though very steep roofs or limited access - common in Beacon Hill, the North End, or parts of Charlestown - can add $50 to $100 for proper safety setup. We tell you this when you call, not when we show up. No surprises on the bill.
Chimney liner replacement in Boston generally ranges from $2,500 to $5,500, with stainless steel liners for wood-burning systems at the higher end and flexible aluminum for gas at the lower. We don't recommend a new liner without camera evidence you can see for yourself, and we'll tell you plainly when work can safely wait another season. Call (857) 597-5950 for an exact quote - estimates are free.
We do - ask when you call. We've got a lot of longtime homeowners in Quincy, Randolph, and Holbrook who've been in their houses twenty years and plan to stay, and we want to make sure they can keep their hearths safe without stretching the budget.
Service & Process FAQs
We lay down protective covers, run a rotary brush up the flue to remove creosote buildup, vacuum the firebox and smoke chamber, and finish with a visual inspection of accessible components. The whole visit takes 45 minutes to 90 minutes for a standard system. In Boston's older housing stock - triple-deckers in Dorchester, colonials in Hingham - we often find bird nests or deteriorated mortar that needs pointing out. You'll get a written report before we leave.
The National Fire Protection Association says once a year for wood-burning systems, and we agree - especially in Boston's climate, where cold snaps start in October and run into April. Oil and gas systems should be inspected annually and swept as needed. If you're burning more than three cords of hardwood a winter in a place like Cohasset or Hull, where the wind off the water drives drafts harder, twice a year isn't excessive.
creosote builds up, and creosote catches fire. A chimney fire can reach 2,000 degrees, crack your flue liner, and let flames into wall cavities or the attic. Even without a fire, a blocked or deteriorated chimney can vent carbon monoxide into living spaces. These aren't theoretical risks - we see the aftermath every winter in Boston neighborhoods where someone waited one season too long. The sweep is cheap insurance.
We sweep year-round, and winter is actually when we do most of our work - Bostonians remember their chimneys when the temperature drops. That said, if you've got an active flue that's been in use, we need it cooled down 24 hours before we can safely work. We book ahead in peak season, so call early.
Yes - we need access to the fireplace or appliance, and we want to walk you through what we found. The camera inspection in particular is something we show you in real time, so you understand your chimney's condition without taking our word for it. We've found homeowners in Revere and Chelsea particularly appreciate seeing the evidence firsthand.
Brands & Parts FAQs
We work with HeatShield, Gelco, and Olympia Chimney for most residential relining jobs in the Boston area. HeatShield's cerfractory resurfacing system is our go-to for restoring clay flue tiles that are sound in structure but have surface deterioration - common in 1920s and 1930s housing stock in Brookline and Newton. Olympia's stainless steel liners handle the heavy creosote loads from older, less efficient wood stoves we see in Randolph and Avon. We spec the right product for your system, not what's on special.
A chimney cap is a metal cover that keeps rain, animals, and debris out of your flue while letting smoke escape. In Boston, where nor'easters drive horizontal rain and squirrels are relentless, a proper cap is essential. We install caps with stainless steel mesh that won't rust out in three years like the galvanized hardware-store versions. A good cap pays for itself in prevented water damage.
We do - Famco makes solid chimney caps, dampers, and termination fittings we use for certain applications around Boston. Their top-sealing dampers are particularly useful in older masonry chimneys where the original throat damper has rusted out or never sealed well, which is common in pre-war housing in Quincy and Chelsea.
Licensing & Insurance FAQs
Every pro working under our name is required to hold the license and insurance Massachusetts requires, and we carry general liability and workers' compensation coverage. Russell Haines, who leads this branch, insists on it. We're also members in good standing of the Chimney Safety Institute of America, and our sweeps train to their standards. We'll show you credentials when you ask - no paperwork, no arguing.
Massachusetts doesn't mandate a chimney inspection at closing, but most home inspectors flag chimneys they can't fully evaluate, and buyers' insurance companies increasingly require a level-2 inspection for wood-burning systems. If you're selling in Milton, Hingham, or anywhere on the South Shore, getting ahead of this with a documented inspection protects your sale price and timeline.
Structural repairs, liner replacements, and rebuilds above the roofline typically require a permit from the Boston Inspectional Services Department or your local building department in Quincy, Revere, or elsewhere. We handle permit applications as part of the job - it's not an extra charge, and it's not something we expect homeowners to navigate alone.
Emergency & Response FAQs
Call the fire department first - even if you don't see flames, a chimney fire can smolder in wall cavities. After the fire department clears the scene, call us at (857) 597-5950 for a level-2 inspection before you use the system again. We document everything for your insurance company, and we'll tell you honestly whether the flue can be relined or if the chimney needs rebuilding. Our hours are Monday through Friday 7:00 AM to 7:30 PM, Saturday 7:00 AM to 6:30 PM, and Sunday 7:00 AM to 6:30 PM.
We book by appointment and work to get you scheduled as soon as possible, especially if you've got no heat or a suspected blockage. During peak season - October through January in Boston - we sometimes book a week out for non-urgent sweeps. If your situation is urgent, tell the coordinator when you call and we'll do what we can. We'll be there when we say.
We're open Monday through Friday 7:00 AM to 7:30 PM, Saturday 7:00 AM to 6:30 PM, and Sunday 7:00 AM to 6:30 PM. Calls are answered by a live coordinator who connects you with the local team. We're not open 24/7, but we return messages promptly during business hours.
Warranty & Guarantees FAQs
We apply The Keystone Standard to every job: 90 days, in writing, no arguing. If something we did isn't right, we come back and fix it. No paperwork, no arguing. For liner installations and major rebuilds, manufacturer warranties apply on top of our own - HeatShield and Olympia both back their products with long-term coverage when installed to spec. We document our work with photos so there's never a question about what was done.
The Keystone Standard is our promise, applied to chimneys: 90 days, in writing, no arguing. It means if our sweep missed something, if a repair fails, if you're not satisfied - we come back. It's stamped on every page of our site and backed by terms you can read. We've been in Boston since 2014, and we plan to be here in thirty years. A company that thinks that way stands behind its work.
We guarantee we'll leave your home as clean as we found it. We use HEPA vacuums, lay down floor-to-ceiling protection, and our sweeps wear shoe covers. In twelve years of work across Boston, from Back Bay condos to capes in Abington, we've learned that respect for the house matters as much as the technical work. Your home first - that's part of our K.E.Y.S. values code. We work in your house the way we'd work in our mother's.
We stop, show you the camera evidence, and explain your options. Nothing gets recommended without photos you can see. We'll tell you plainly when work can wait, when it should be done before the next burning season, and when it's unsafe to use the system. We've talked homeowners in Hull and Holbrook out of unnecessary work when the flue was sound, and we've insisted on immediate repairs in Roslindale when the liner was cracked. A square deal means honest counsel, not the biggest invoice.
