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.

A chimney sweep in Medford, MA typically costs between $189 and $289 for a standard single-flue cleaning before any repairs, depending on the stack’s age and condition.

We know Medford’s housing stock because we work in it every week. Late-Victorian triple-deckers off Salem Street, two-families near Mystic Avenue, Capes and ranches up toward the Fellsway: each has its own chimney story, but most share the same underlying problem. These are old stacks, built for coal, converted to oil or gas, and often left with flues that were never relined or properly cleaned. That’s where our Chimney Sweep team earns its keep.

Chimney Cleaning in Medford
Chimney cleaning in Medford means removing creosote (the tar-like, flammable buildup that causes chimney fires) and soot from the interior walls of your flue. Most Medford homes need this once a year if they burn regularly during heating season, or at least every two years for occasional use. A standard chimney cleaning in Medford runs $189 – $289 for a single flue.
Why Older Medford Stacks Need Annual Attention
Medford’s 1895 – 1925 triple-deckers were built with masonry chimneys designed for coal. When those homes converted to oil or gas, the flues were rarely relined. Clay tiles crack, mortar joints open up, and creosote from wood fires finds every gap. A chimney that has gone 20 years without cleaning is not just dirty. It’s structurally questionable. We clean what’s there, but we also show you what the camera sees so you can make an informed call.
What a Sweep Actually Involves Here
We set drop cloths, run a HEPA-filtered vacuum, and brush the flue from top to bottom or bottom to top, depending on access. Then we run a camera through to confirm the flue is clear and check for cracks, gaps, or deteriorated mortar. If we find third-degree creosote (the shiny, tar-glazed kind that brushes alone won’t remove), we’ll tell you and show you, then explain what treatment options actually work. No scare talk. Just real findings.
Fireplace Cleaning in Medford
Fireplace cleaning in Medford focuses on the firebox, damper, smoke shelf, and the visible brickwork where your fire actually burns. It’s typically included as part of a full sweep. If you’re mainly concerned about the firebox and the damper area because you only burn occasionally, a fireplace cleaning in Medford runs $149 – $249 depending on buildup and access. For gas fireplace issues, we also offer Gas Fireplace Repair - Medford.
When a Fireplace Cleaning Alone Makes Sense
If you use your fireplace for a handful of weekend fires each winter, the flue above the damper may stay relatively clean while the firebox fills with ash, soot, and creosote flakes. We still recommend a camera check while we’re there. A clean firebox means nothing if the upper flue is packed with debris you can’t see from the hearth.
What We Check During Every Fireplace Cleaning
We inspect the damper operation, clear the smoke shelf, vacuum the firebox, and check for cracked firebrick or loose mortar joints. In Medford’s older homes, we frequently find smoke shelves so packed with spalled brick chips and creosote that the fireplace drafts poorly. We’ll show you before-and-after photos of your own firebox.
Trusted Brands We Service in Medford
When a Medford chimney needs liner repair, resurfacing, or a component replaced, we use materials professionals specify: HeatShield for flue resurfacing, Gelco and Olympia Chimney for caps and dampers, and Famco for termination components. We stock the common parts Medford chimneys actually need, which means fewer follow-up visits and faster turnarounds for repairs flagged during a sweep. Box-store substitutions don’t hold up in a river-valley climate with this much freeze-thaw cycling. We don’t install them.
Common Chimney Sweep Problems We See in Medford Homes
- Shared stacks across multiple units. Triple-deckers with two or three flues in one stack are the norm in Medford, not the exception. A creosote blockage in one flue can fill a neighboring unit with smoke or carbon monoxide, even if that unit’s flue is clean.
- Capped but uncleaned flues from forced-air conversions. Landlords near Tufts routinely cap upper flues when switching to forced-air heat. The debris and moisture trapped inside those sealed flues eats at the shared masonry for decades.
- River-valley humidity accelerating mortar deterioration. Medford sits in the Mystic River drainage basin. Ambient moisture repeated freezes and thaws in the brickwork all winter, opening joints and cracking crowns faster than in higher, more inland towns like Arlington or Woburn.
- Makeshift flue seals that fail. We find flues stuffed with insulation, plywood, and even plastic sheeting in older converted homes. These seals trap moisture and animal nests, quietly destabilizing the stack every household in the building relies on.

FAQs About Chimney Sweep in Medford
Yes. All three flues typically run through the same masonry stack separated only by a single wythe of brick or clay tile. When one flue blocks and creosote ignites, the fire can crack the separating walls and spread into adjacent flues, filling neighboring units with smoke and carbon monoxide before anyone sees flames. The most dangerous part is that you won’t know your neighbor’s flue is packed until it fails. If you live in a shared-stack building in Medford, get every flue camera-checked, not just the one your unit uses. Call (336) 863-3889 and we’ll look at the entire stack.
Because Medford’s river-valley humidity attacks chimneys from the inside out. The Mystic River drainage basin keeps ambient moisture high all heating season. That water gets absorbed into the brick, freezes overnight, and expands, opening mortar joints and cracking the crown. The exterior brick can look perfectly sound while the interior flue tiles are cracked, shifted, or spalling into the flue itself. The street-level look tells you almost nothing. A camera inspection tells you everything. We show you the footage before recommending anything, and if the chimney is genuinely fine we’ll tell you that too.
Yes, and this is one of the most common hidden problems in Medford’s converted triple-deckers and two-families. When owners cap upper flues during a forced-air conversion, they almost never clean those flues first. After 20 to 40 years, the capped flues hold compacted soot, animal nests, and trapped moisture that slowly breaks down the shared masonry. We’ve opened capped flues off Boston Avenue and found debris packed to the top of the chase. The fix is to clean the flue, install a proper cap, and let the stack breathe. Call (336) 863-3889 and we’ll camera the capped flues before you make any decision.
Every two years at minimum, even if you burn only a few times each winter. The reason is that Medford’s freeze-thaw cycle and river-valley humidity weather the stack regardless of whether you use it. Mortar joints open, crowns crack, and animals build nests in uncapped flues just as readily in an unused chimney as a used one. An annual sweep is best if you burn regularly. If you truly barely burn, a Level 1 inspection plus a light brush every other year catches structural problems before they become expensive liner repairs. We’ll tell you honestly if a year is enough or if you can safely wait.
A camera inspection shows the actual interior condition of your flue: cracked clay tiles, opened mortar joints, hidden creosote glaze, abandoned flues packed with debris, and transition points where appliances vent into stacks never designed for them. A brush-and-vacuum removes what’s on the surface but tells you nothing about what’s behind the soot. In Medford’s century-old stacks, the camera frequently reveals damage that changes the entire repair recommendation. We were called to a three-unit triple-decker off Boston Avenue where a downstairs tenant reported smoke drifting into the kitchen. The camera showed one active flue, one capped-but-uncleaned flue packed with compacted debris and an old animal nest, and a third flue sealed with makeshift materials and spalling mortar. We showed the homeowner the footage before recommending anything: a HeatShield liner repair on the active flue and a full sweep-and-cap correction on the abandoned ones, then documented the crown cracking for follow-up. That’s how we work on every Medford chimney: show the evidence, then let the homeowner decide.
If you live in Medford and haven’t had your flue camera-checked, call Alcott Chimney Sweep at (336) 863-3889. We’ll schedule a sweep, show you exactly what’s inside your stack, and put every repair price in writing before work begins. No pressure, no vague warnings, just evidence and a plan.
