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.

AfterFast, Reliable Chimney Sweep Across Malden
A proper chimney sweep in Malden typically costs $180 – $340 for a standard single-flue cleaning, and for most triple-decker owners the real question isn’t the price, it’s how many flues you actually have. Alcott Chimney Sweep has worked Malden’s older housing stock long enough to know that a “one-flue sweep” off Salem Street or Highland Avenue often turns out to be three. We’ll send a background-checked, identity-verified technician to your door with a name and photo you’ll see before we arrive, and a written price before any work starts. Call (336) 863-3889 to talk to a live person, day or night.
Why Alcott Chimney Sweep Is Malden’s Preferred Chimney Sweep Company
Homeowners in Malden call us because we treat the job as a shared-stack problem, not a single-hearth chore. The city’s triple-deckers, concentrated along Maplewood, Linden, and the streets fanning out from downtown, were built with one flue per unit. When three units share one brick stack and each has a different heating appliance venting into it, the sweep cannot be a quick brush-and-go. Our Chimney Sweep team documents every flue with a camera and sends you a photo report you can actually read. You’ll know the technician’s name and see their photo before we arrive, and that technician will show a photo ID badge at the door. Every visit includes a written price before work begins, a written guarantee on any repair, and a free second visit if a repair fails within the coverage period. That’s the 365-Day Done Right Promise, and it applies to every job we do in Malden.
Chimney Sweep Services in Malden
Chimney Sweep Services in Malden mean something different than they do in a single-family suburb like Melrose or Medford. Here, a stack serves multiple units, and the sweep has to account for every flue, every appliance, and every unit owner’s history of conversions and repairs. A standard sweep in Malden runs $180 – $340 depending on flue count, creosote stage, and accessibility. A Level 1 inspection runs $150 – $250 and is included with most sweeps. A Level 2 inspection, which we recommend whenever a unit has changed heating fuel or you’re buying or selling, runs $300 – $500. Here’s what the work actually covers on a Malden job.
Sweeping and Creosote Removal
Creosote, the tar-like byproduct of wood and oil combustion, builds up in flues over every burning season. First-degree creosote is fluffy and brushable. Third-degree creosote is a hardened glaze that a brush cannot touch. In Malden’s older stacks, where oil-fired boilers and wood-burning fireplaces still run through long winters, we remove what’s removable and tell you plainly when a glaze requires chemical treatment or relining.
Inspection and Photo Documentation
Every sweep we perform in Malden includes a camera inspection of each accessible flue in the stack. You’ll receive a photo report showing the condition of the flue tiles, mortar joints, and any blockages or deterioration. That report is yours, and it’s what we use to recommend any follow-up work. We don’t recommend repairs without showing you the evidence.

Chimney Cleaning in Malden
Chimney Cleaning in Malden is not a one-size-fits-all job because Malden’s stock of triple-deckers and two-families means most stacks serve multiple flues with different histories. The cleaning cost in Malden runs $180 – $340 for a standard job; flues with heavy creosote or multiple bends run toward the higher end. If we find three flues where one was expected, the price reflects the additional scope, and we’ll give you that price in writing before we begin.
Oil and Gas Flue Cleaning
Many Malden units still run oil-fired boilers as primary or backup heat. Oil produces soot and sulfur-laden deposits that cling to clay flue tiles. Gas appliances produce acidic condensate that attacks aging lime mortar and brick. A proper cleaning addresses the specific deposit type, not just the generic “soot.” We’ll tell you what’s in your flue and what it means for the safety of every unit sharing the stack.
Annual Sweep and Maintenance
For most Malden homeowners, one cleaning per year is the right cadence, ideally in late summer or early fall before burn season starts. If you burn wood regularly or run an oil boiler through winter, we may recommend a second mid-season check. The goal is to prevent creosote from reaching the point where a spark becomes a chimney fire, not to sell you a service you don’t need.
Trusted Brands We Service in Malden
When a Malden flue needs a liner, a crown repair, or a full rebuild, we use the materials chimney professionals specify, not what’s cheap at a box store. We install and service liner systems from HeatShield and resurfacing products from Gelco, and we stock common fittings locally so turnaround on Malden jobs is fast. If your triple-decker stack needs three different liners because each flue vents a different appliance, we’ll size each one correctly and show you the specs before installation. No generic alternatives, no improvising.
Common Chimney Sweep Problems We See in Malden Homes
- Three flues where one was expected. Malden triple-deckers were built with one flue per unit, and when you book a sweep, you may not know how many flues are actually in the shared stack. Our techs find this on a regular basis off Salem Street, Maplewood, and Highland Avenue.
- Mismatched oil-to-gas conversions. A second-floor owner swaps an oil boiler for a high-efficiency gas furnace and leaves the old unlined clay flue in place. The oversized flue pools acidic condensate and vents improperly into a stack still shared with a working oil system two floors up.
- Freeze-thaw damage on exposed stacks. Malden’s brick chimneys rise well above rooflines on closely spaced triple-deckers, and dozens of freeze-thaw cycles each winter spall the original lime mortar and crack brick faces. What looks like cosmetic wear is often structural degradation.
- Decades of uncoordinated repairs. One unit relines a flue, another patches a crown with mismatched brick, a third ignores the joint entirely. Draft failures that cross unit boundaries are the result, along with carbon monoxide risks no single landlord sees on their own.

FAQs About Chimney Sweep in Malden
Most Malden triple-deckers need a sweep and inspection once a year, before the burn season starts in the fall. If any unit burns wood regularly or runs an oil boiler through a long winter, a second mid-season check is smart. The cadence has less to do with the calendar and more with what’s actually burning in each flue. Call (336) 863-3889 and we’ll help you figure out a schedule that matches what’s in your stack.
Yes, in practice all three units need to know what’s happening in the shared stack, because a draft failure or carbon monoxide leak in one flue affects every unit in the building. We’ll document each flue with the camera, send the photo report to all three unit owners, and make recommendations they can act on together. Call (336) 863-3889 and ask for a stack-wide inspection if you’re not sure what’s in your building’s chimney.
A proper sweep in Malden starts with identifying every flue in the stack, then brushing out what’s removable, then running a camera through each flue to document condition. You get a photo report showing what we found and what we recommend. If a repair is suggested, the photos are your evidence. Call (336) 863-3889 and we’ll walk you through the process before you book anything.
First-degree creosote is a soft, fluffy deposit that a chimney brush removes easily. Third-degree creosote is a hardened tar glaze that a brush cannot touch and that ignites at high temperatures, and in Malden’s older oil- and wood-burning flues it’s more common than homeowners expect. If we find a glaze, we’ll tell you plainly and quote the proper treatment. Call (336) 863-3889 for an inspection if you suspect you’re burning one flue hard every winter.
Crumbling mortar on an exposed Malden chimney is a real deterioration problem, not a cosmetic one, because water getting into the brick face expands and contracts through dozens of freeze-thaw cycles each winter and accelerates spalling. How soon it needs repair depends on how much mortar is gone and where. We’ll look at it, show you photos, and tell you honestly whether it can wait. Call (336) 863-3889 and we’ll take a look.
