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.

AfterDuraFlex Chimney Cleaning in Boston, MA | Level Two Chimney Boston
Chimney Cleaning & Sweep - Boston for DuraFlex usually runs between $229 and $429, depending on flue condition and whether you own one of the city’s many shared triple-decker stacks. We’re an independent DuraFlex service provider covering every Boston neighborhood from Dorchester to Brighton. The one thing that makes our work here different: we camera-scan every DuraFlex liner before and after cleaning, so you see exactly what we saw. Call (857) 567-8887 for a written quote before anyone sets foot on your roof.
Why Boston Residents Choose Us for DuraFlex Service
Most chimney companies in Boston can sweep a flue. Few can tell you why a DuraFlex 316L liner is scaling inside a South Boston triple-decker after six seasons, or whether that hairline crack at the roofline is age or the slow lean of a Back Bay brownstone built on filled tidal land. Our techs work on DuraFlex liners inside Boston’s oldest housing stock every single week. That’s the difference between a company that sells chimney cleaning and one that documents liner condition.
Corrine Halstead leads our Boston crew. She learned flue measurement, liner assessment, and draft diagnostics at BOCES Rockland in New York before building her reputation across Greater Boston, including years of inspection work on the older triple-deckers along Dorchester Avenue. Her rule holds on every job: name the problem, give the measurement or condition, state the cost, then talk about anything else. We background-check every technician, and each visit ends with a written scope, written warranty, and a photo record filed under DuraFlex sales & service history for your address.
Common DuraFlex Chimney Cleaning Problems We Solve in Boston
- Glazed creosote inside 316L liners on shared triple-decker flues. When three units in Dorchester or South Boston burn wood in one shared flue on three different schedules, the deposits bake into a hard, shiny glaze that a standard brush won’t touch. We use chemical treatment, then re-scan the liner to confirm the DuraFlex wall is clean and intact.
- Kinked or sagging liners at the smoke chamber from rooftop settlement. Back Bay and South End brownstones sit on filled tidal land. Decades of differential settlement lean the masonry, and an improperly supported DuraFlex liner kinks right where the flue narrows. We spot this on camera before it collapses.
- Pinhole corrosion on aluminum DuraFlex liners from condensing gas flue gases. Boston’s freezing cycles and that Atlantic salt air in East Boston, South Boston, and Charlestown accelerate the condensation-caused rot that eats aluminum liners from the inside out. Inspection shows rust-through that a visual look from the top would miss.
- Liner ovalization and joint separation at the roofline. The same differential movement that cracks brick also pulls DuraFlex joints apart where the liner exits the chimney. We find separated joints on brownstone rooflines that no one noticed because no one looked.
- Improperly sized liners left over from fuel conversions. Boston’s 1870s-to-1920s chimneys were built for coal, then converted to oil, then gas. The old DuraFlex liner installed for one fuel is often badly oversized for today’s high-efficiency appliances, producing condensation that accelerates creosote and corrosion.
BeforeAfterDuraFlex Service in Boston: What Local Conditions Mean for Your Equipment
Here’s something you won’t read on a generic DuraFlex page. Boston’s triple-decker chimneys, most built before 1920, often share a single flue across three rental units, and fragmented cleaning schedules are the leading local reason a DuraFlex liner goes seasons without service. One tenant assumes the landlord handled it. The landlord assumes the tenant on the first floor called someone. Nobody did. We’ve walked onto Dorchester and Roxbury roofs where the same flue had three different tenants’ fireplaces feeding into it, and the glazed creosote inside the DuraFlex was thick enough to look like a lava tube. That pattern doesn’t show up in Newton or Milton, where single-family homes have one owner and one schedule. In Boston, shared flues demand a documented, recurring cleaning calendar and a landlord who keeps the photo record on file for Massachusetts 527 CMR fire code compliance.
DuraFlex Models & Products We Service in Boston
We inspect, clean, and service the full DuraFlex lineup: the 316L stainless steel liner, the Aluminum liner, and the DuraFlex Pro system. For Boston Chimney Repair work, we use DuraFlex OEM components when available. For old or discontinued sections, we recommend high-quality 316L stainless or aluminum aftermarket parts and note the difference in writing before we order anything. We stock common DuraFlex fittings locally so Boston turnaround is measured in days, not weeks. And we replace rather than patch liners that show structural degradation or can’t be cleaned properly. A patched liner in a salt-exposed East Boston chimney buys you two seasons, not ten.

FAQs - DuraFlex Chimney Cleaning in Boston
Yes, we can clean the shared flue from the roof even if only one floor’s tenant called. But the bigger issue is that the other two fireplaces feeding that same flue likely need cleaning too, and their schedules matter for how fast the creosote returns. We document the shared-flue condition in the photo record and recommend the landlord consolidate all three units onto one cleaning calendar. Call (857) 567-8887 and we’ll price the full stack.
Salt air in East Boston, South Boston, and Charlestown accelerates the corrosion that condensing gas flue gases already cause in aluminum DuraFlex liners. The liner rots from the inside and the salt air attacks exposed metal at the top termination. A 316L stainless liner holds up far better in these neighborhoods. Camera inspection tells us which you have and what’s left of it.
Yes, most repointing work on Boston chimneys can be done with the DuraFlex liner left in place. We protect the liner, grind out deteriorated lime-mortar joints, and repoint with mortar matched to your building’s era. If the liner itself is compromised, we’ll tell you before anyone starts grinding so you can decide on replacement with a written price for both options.
Yes, chemical creosote treatment is safe for DuraFlex 316L stainless steel liners when applied correctly by a trained sweep. The treatment dissolves glazed creosote that brushing can’t remove. We follow up with a camera scan to confirm the liner wall is clean, then file the before-and-after images in your job record. Call (857) 567-8887 to schedule a Level 2 inspection first.
Yes, many Boston chimneys built in the 1880s through 1920s never had clay tile liners, and a properly sized DuraFlex 316L liner is exactly what they need to meet current fire code. We measure the flue, calculate the draft, and install the liner with correct support, then document the finished condition with camera scans and a written warranty.
