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.

Why Alcott Chimney Sweep Is Boston’s Preferred Chimney Inspection Company
We’ve been inspecting chimneys since 2002, and the bulk of what we see in Boston is the same thing over and over: century-old flues that were never designed for the gas appliances now venting through them. Our technicians know the difference between a triple-decker in Dorchester with four flues sharing one masonry chase and a Back Bay brownstone with a single rubble-stone flue that hasn’t been touched since the Coolidge administration. That matters, because the inspection approach is not the same for both.
Every Boston customer gets the Threshold Standard before the truck ever pulls onto their street. The technician’s name and photo are sent to you ahead of the appointment, they carry a photo ID badge, and they pass a background check and identity verification before they ever set foot on your property. Ruben Castellano built this company on the idea that you should know exactly who is walking through your door. If you’re home alone or have kids in the house, that’s not a nice-to-have. It’s the reason you called us.
Our Chimney Inspection team has worked in every corner of Boston, from the triple-decker blocks off Blue Hill Avenue to the landmarked streets of Beacon Hill. We know where the old coal flues hide, where the salt air eats mortar fastest, and which historic district boards need to sign off before a cap or liner gets installed. That local knowledge is part of what you’re paying for.
Chimney Camera Inspection in Boston
A chimney camera inspection in Boston is the only way to actually see what’s happening inside a flue that’s older than the MBTA. We run a high-resolution video camera down the full length of the flue and record the entire path, looking for cracked clay tiles, gaps in mortar joints, creosote buildup, and liner deterioration that you’d never catch from a visual-only look from the rooftop or firebox. In Boston, where most chimneys predate 1940, we recommend a camera inspection as part of any Level 2 evaluation, especially before buying a home or after switching heating fuel.
What the Camera Actually Shows You
You don’t have to take our word for anything. We pull the feed and show you exactly what the camera saw: the crack, the gap, the creosote, or the clean flue if that’s what’s there. If we recommend work, you’ll have seen the reason with your own eyes first.
When Boston Homeowners Need It
You need a camera inspection if you’re buying a triple-decker in Dorchester or South Boston and want to know which of the three or four flues in the shared chimney stack actually needs work. You need it before you switch from oil to gas, because Massachusetts code requires a correctly sized liner and the camera tells us if the existing one qualifies. You also need it if you smell something odd when the heat kicks on or if it’s been more than two years since anyone looked past the firebox.
A standard Level 1 visual inspection runs $249 – $349. A Level 2 inspection with camera, which we recommend for most Boston homes, typically runs $349 – $449. If we’re doing a full Level 3 inspection because significant damage is suspected, that runs $549 – $649.
Fireplace Inspection in Boston
A fireplace inspection in Boston is a detailed look at the firebox, damper, smoke shelf, and the flue connected to that specific fireplace, and in this city it often reveals problems that started long before you bought the house. We inspect the firebrick for cracks and spalling, check that the damper actually opens and seals, and we camera the flue above the firebox to confirm it’s safe to burn. For most Boston homes, especially pre-1940 buildings in neighborhoods like the South End and Beacon Hill, this is not a quick peek with a flashlight.
Dampers and Draft Problems
Old Boston fireplaces usually have original cast-iron dampers that have warped or rusted open, which means you’re paying to heat the sky all winter. A proper fireplace inspection tells you whether you can burn safely and whether your damper is actually doing its job.
Before You Buy or Sell in Boston
Real estate transactions in Boston move fast, and a fireplace inspection is often the thing that catches a buyer off guard after closing. If you’re under contract on a condo in a converted brownstone, get the fireplace inspected before you sign. The $349 – $449 for a Level 2 inspection is a lot cheaper than finding out in February that the flue behind your living room wall was abandoned decades ago and never properly sealed.
Trusted Brands We Service in Boston
We install and service chimney systems from the brands professionals actually specify: DuraFlex liner systems, HeatShield resurfacing, and Olympia Chimney. These are not box-store substitutes. We keep common replacement components and liner parts stocked for fast turnaround on Boston jobs, which means if your April inspection turns up a cracked terra cotta tile, we can usually get the repair done the same season rather than making you wait through the fall rush. When we recommend a liner, we’ll tell you the exact brand and product we’re proposing, and the camera footage shows you why it’s needed.
Common Chimney Inspection Problems We See in Boston Homes
- Multi-flue stacks in triple-deckers with wildly different conditions per flue. In a single Dorchester chimney chase holding three or four flues, the first-floor flue is almost always in worse shape than the third-floor flue. Rising heat keeps the upper flue drier, while the bottom flue collects moisture and acidic condensate that eats clay tiles from the inside.
- Unlined or rubble-stone flues in pre-1940 buildings. Back Bay and Beacon Hill brownstones often still have original flues that were built for coal and never lined for modern use. These chimneys were never designed to handle the exhaust from a gas furnace or water heater, and they fail in predictable ways we see constantly.
- Freeze-thaw damage from Boston winters. Boston averages 43 inches of snow a year, and every freeze-thaw cycle pushes moisture deeper into old mortar joints. The result is spalled brick, cracked crowns, and water intrusion that accelerates everything else going wrong inside the flue.
- Gas appliances vented into abandoned flues. Massachusetts code requires a correctly sized liner when fuel type changes, but plenty of older Boston homes have gas furnaces venting into coal or oil flues that were never relined. That’s a code violation and a direct route for carbon monoxide into living space.

FAQs About Chimney Inspection in Boston
Because the flues inside a shared triple-decker chimney stack do not age at the same rate. The first-floor flue in a Dorchester or South Boston three-decker usually collects the most moisture and acidic condensate, while the third-floor flue stays drier and often looks nearly clean because rising heat keeps it that way. Massachusetts code requires a correctly sized liner that matches each individual appliance. If you inspect only the easiest flue to access, you miss the one most likely to fail. Call (336) 863-3889 for a per-flue inspection with camera evidence on each one.
Yes, under 248 CMR Massachusetts requires a correctly sized liner when an appliance changes fuel type, and an old oil flue is usually the wrong size and wrong material for a gas appliance. Switching from oil to gas without a proper liner violates code and can push carbon monoxide into the living space. We provide a camera inspection that shows exactly what’s in your flue now, and we only recommend a change when the code and the footage both support it. Call (336) 863-3889 before you schedule the fuel conversion.
You should have a Level 1 visual inspection every year if you burn wood, and a Level 2 camera inspection every two to three years for any chimney serving a heating appliance, especially in a pre-1940 Boston building. Older flues deteriorate faster, and Boston’s freeze-thaw cycles accelerate the damage. If you haven’t had a camera inspection since you bought the house, start there. Call (336) 863-3889 to schedule one.
It finds cracked clay tiles, gaps in mortar joints, creosote buildup you can see, liner corrosion, and sometimes evidence that a flue was abandoned or never lined in the first place. In older Boston homes, it frequently reveals that the chimney stack behind your walls was built for coal in 1910 and never upgraded for modern heating equipment. You see every finding on the camera feed before anyone recommends a repair. Call (336) 863-3889 to schedule a camera inspection.
No. Nothing gets recommended without camera evidence that you watch with your own eyes. In a Dorchester triple-decker off Adams Street, we camera’d all three flues in a shared chase and found a cracked clay-tile liner on the first-floor flue while the third-floor flue looked nearly clean. We recommended a HeatShield liner for that one flue only and left the other two alone. The owner said no previous sweep had ever shown them the inside of the stack. That’s how we work in Boston. Call (336) 863-3889 and see the evidence for yourself.
