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 Lynn
A standard chimney sweep in Lynn runs $189 – $289 for a single flue, and most triple-decker jobs with two or three flues fall between $340 and $690 depending on creosote stage and access. Our crews work Lynn’s tight side streets and triple-decker blocks every week, so we know what these aging masonry stacks throw at us before we even set the ladder. If you’re in the Diamond District, Lower End, or anywhere off Lynn Shore Drive, call (336) 863-3889 and we’ll get you on the schedule.
Why Alcott Chimney Sweep Is Lynn’s Preferred Chimney Sweep Company
Lynn homeowners call us because we treat the shared-flue reality of this city’s housing stock as the rule, not the exception. A detached single-family home in Peabody has one flue to worry about. A triple-decker on Essex Street might have three active flues in one salt-weathered stack, and we inspect every one of them independently. Ruben Castellano built Alcott Chimney Sweep around a simple standard: before any technician walks up your porch stairs, you’ll know their name, see their photo, and have a written price in hand. No surprises at the door. No vague promises.
Every Alcott technician has passed a background check and identity verification under the Threshold Standard. That’s not an add-on for us. It’s how we’ve operated since 2002, and it’s why single parents, older homeowners, and people who are home alone during the day choose us over anonymous crews from a call center. Our Chimney Sweep teams dispatch from our Boston office and serve Lynn directly, so you’re never waiting on a truck coming from the other side of the state.
We don’t ask Lynn homeowners to trust us blindly. You’ll see the technician’s name and photo before the visit, they’ll show a photo ID badge at the door, and you’ll have a written price before any work starts. If a repair fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it’s in writing on every job.
Chimney Cleaning in Lynn
Chimney cleaning in Lynn means removing creosote (the tar-like buildup that causes chimney fires) and soot from flues that were often built for coal furnaces a hundred years ago and later converted to oil or gas. Those oversized clay liners run too cool for modern appliances, so exhaust condenses inside and leaves deposits that a properly sized flue wouldn’t collect. A standard single-flue sweep in Lynn runs $189 – $289. Two-flue and three-flue triple-decker stacks cost more, and we’ll give you an exact number before we start.
What a sweep covers on a Lynn triple-decker
We sweep each flue separately, remove the creosote and soot from the smoke chamber and firebox, and note any liner cracks, missing mortar, or cross-draft we find along the way. Because Lynn stacks often carry three flues side by side, we pay close attention to what’s happening between them. A crack in one flue liner can let smoke from a wood stove on the top floor drift into an oil flue below. We flag that before it becomes an odor complaint from the neighbor.
When to book a cleaning
If you burn wood, sweep once a season. If your flue vents oil or gas, every one to two years keeps creosote from glazing into third-degree, which is the dense, hardened stage that’s genuinely dangerous to remove from an old Lynn flue. The salt air off Lynn Harbor doesn’t make creosote worse directly, but it does weaken the mortar around the flue, and loose mortar joints let more moisture in, which accelerates the whole cycle.
Fireplace Cleaning in Lynn
Fireplace cleaning in Lynn covers the firebox, damper, smoke shelf, and the visible portion of the flue above the damper. For Lynn homes with converted coal-era fireplaces, the damper is often original, rusted, or stuck open, which means cold air pours down the chimney all winter and heat rushes out. A fireplace cleaning in Lynn runs $150 – $220 for a single fireplace, and we always check the damper and smoke shelf as part of the job, not as an extra line item.
What changes with older Lynn fireplaces
The fireplaces in Victorian-era Lynn homes and triple-deckers are typically shallow and built for coal, not wood. If someone converted one to burn wood, the smoke shelf is often undersized and collects soot fast. We clean that shelf every time, because a clogged smoke shelf is one of the most common causes of a smoke-filled living room on a windy Lynn night.
Gas fireplace service too
If you have a gas insert in an old masonry fireplace, we service those as well. The fireplace cleaning covers the glass, logs, burner, and pilot assembly, and we check the vent run for the same salt-driven corrosion that eats away at the exterior brick. That’s a Lynn-specific problem: a gas fireplace in Woburn isn’t pulling in ocean air, but one three blocks from Lynn Harbor is.
Trusted Brands We Service in Lynn
We install and service the gear chimney professionals actually specify: DuraFlex stainless steel liner systems, HeatShield resurfacing for cracked clay liners, and Famco caps and dampers. We also work with Copperfield components for many of the older Lynn fireplaces we open up. We keep common parts stocked for the brands we service, so most repairs on Lynn jobs don’t wait on a shipment from out of state. If your liner needs a patch or a full resleeve, we’ll give you a line-item price in writing before anything gets ordered.
Common Chimney Sweep Problems We See in Lynn Homes
- Shared-flue cross-contamination. A triple-decker on a Lynn side street can run three active flues in one stack, and a cracked clay liner lets a wood stove’s exhaust drift into an oil flue next door. The second-floor tenant smells oil exhaust, and the source is two floors up.
- Salt-weathered mortar and spalling brick. East- and south-facing chimneys near Lynn Harbor take persistent salt spray that etches mortar joints and flakes brick faces. Nor’easters drive saturated air into the open joints, and freeze-thaw cycles widen the cracks every winter.
- Cool-running converted coal flues. Flues built for coal are too wide for modern oil and gas appliances, so exhaust cools too fast and condenses inside the liner. That produces first-degree creosote that turns into third-degree if the sweep is skipped for a few years.
- Mixed-use stacks with mismatched liners. We routinely see a wood stove retrofitted into a flue sized for a coal furnace, running next to an oil flue from another unit, all inside one aging masonry chase. Each liner has to be inspected independently for sizing, cross-draft, and creosote stage.
Pricing for Chimney Sweep in Lynn, MA
A single-flue chimney sweep in Lynn runs $189 – $289. Two flues in the same stack typically run $340 – $490, and a full three-flue triple-decker sweep runs $520 – $690.

FAQs About Chimney Sweep in Lynn
If a flue hasn’t been run in years, inspect it before anyone uses it again. Dormant Lynn flues are often home to cracked liners, missing mortar, debris, or even a bird’s nest, and those problems don’t show up until the first fire pushes smoke back into the living room. If the building is a triple-decker, inspect all three flues even if only one fireplace will be used, because they share a stack and a problem in one flue can bleed into the others. Call (336) 863-3889 to book an inspection, and we’ll walk you through what we find before quoting any repair.
An oil smell in one unit’s living room usually means exhaust from an adjacent flue is migrating sideways through a cracked liner or open mortar joint in the shared masonry stack. We found exactly this in a Diamond District triple-decker, where a top-floor wood stove flue had cracked and was sending smoke into the lower oil flue. We installed a HeatShield liner in the wood flue, sealed the smoke chamber, replaced the failed cap, and the smell stopped. If you smell oil exhaust when the heat runs, don’t wait. Call (336) 863-3889 and ask for a Level 2 inspection.
Yes. The salt spray off Lynn Harbor accelerates mortar erosion and brick spalling on east- and south-facing chimneys, especially on roads close to the water like Lynn Shore Drive. Once the mortar joints open up, nor’easter moisture soaks in, freezes, and widens the cracks. Homes a few miles inland don’t get the same constant salt exposure. If your chimney faces the harbor, an annual inspection catches joint damage before it becomes a rebuild.
Third-degree creosote is the hardened, glazed, tar-like stage that forms when earlier creosote deposits are repeatedly heated and cooled. In Lynn’s converted coal-era flues, it’s especially common because the oversized liner runs cool and encourages condensation. Third-degree creosote can’t be brushed out with standard sweeping. It requires chemical treatment or relining, and it’s the exact situation where we recommend a liner solution like HeatShield or a DuraFlex resleeve. Call (336) 863-3889 and we’ll tell you honestly whether your deposits are first-degree, second-degree, or the problematic third-degree.
Yes, one visit is standard. We sweep each flue in the stack individually, working from the roof or the clean-out ports depending on access, and we check each one for liner cracks, cross-draft, and creosote stage as we go. A three-flue Lynn triple-decker sweep typically runs $520 – $690, and you’ll have a written price before we start. Call (336) 863-3889 to schedule all three flues in one appointment.
How Lynn’s Shared Flues Create a Real Cross-Contamination Risk
Here’s what a generic chimney sweep page won’t tell you: in Lynn’s triple-decker blocks, the three flues sharing one masonry stack are not isolated from each other. They’re separated by clay liners and mortar that have been soaking up salt air off Lynn Harbor for a century or more. When the liner in one flue cracks, exhaust from a top-floor wood stove can migrate sideways into the oil flue below. It’s not a theory. We were called to a triple-decker in the Diamond District where the second-floor tenant kept smelling oil exhaust in the living room. Our tech ran a Level 2 inspection and found a cracked clay flue liner on the top-floor wood stove flue, allowing third-degree creosote and smoke to migrate sideways through the shared masonry stack into the lower oil flue. We installed a HeatShield liner in the wood flue, sealed the smoke chamber, replaced the failed chimney cap, and the cross-contamination smell stopped. That condition is far more common in Lynn than in inland Peabody or Saugus, where detached single-family homes usually have one appliance per stack.
This is the exact reason we inspect every flue in a Lynn stack individually, even if only one fireplace is in use. A clean flue next to a failing flue is not a safe flue. If you live in a Lynn triple-decker and smell oil exhaust, smoke, or just something off when the heat or a neighbor’s fire is running, call (336) 863-3889. We’ll find the source and give you a written fix, not a scare tactic.
