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 Repair Across Chelsea
Chimney repair in Chelsea, MA usually means working on buildings with several flues under one roof, not a single fireplace. We know the triple-deckers off Broadway, the two-families near Chelsea Square, and the older singles scattered through Bellingham Hill and Prattville. Our crews arrive in uniform, background-checked, and every job starts with a written price before any work begins. Call (830) 251-4560 and a live person answers, any hour, any day.
Why Flint Chimney Sweep Is Chelsea’s Preferred Chimney Repair Company
Most of what we do in Chelsea is Chimney Repair on buildings that have been through decades of coastal weather and heavy use. The dense multifamily stock here means one rooftop can carry three or four flues, each with its own liner, crown, cap, and flashing. We treat every flue as its own job, with its own camera report. That matters when a third-floor rental flue is failing but the first-floor owner flue is fine. You get a straight answer on both, not a scare quote.
Flint Chimney Sweep has operated since 2002 as part of the Garrison Partners family. Every repair carries a written one-year guarantee under the 365-Day Done Right Promise. If a covered repair fails within that year, we return at no charge. No argument, no re-quote, no “well, technically it was a different issue.” The price we put in writing before we climb the ladder is the price on the invoice. Hank Delano leads our team, and the Garrison Standard is the code every technician follows.
Chimney Cap Installation in Chelsea
Chimney cap installation in Chelsea is one of the highest-value repairs we do on older multifamily buildings. A cap sits over the flue opening and does two jobs: it keeps rain and snow out of the flue, and it stops animals, leaves, and loose debris from dropping into the smoke chamber. On a triple-decker, one missing cap can send water into three units below, because the flue runs straight down through all of them.
A standard stainless cap install in Chelsea typically runs $180 – $320 per flue, depending on flue dimensions and roof access. On a two-flue chimney, you’re looking at two caps. We quote per flue, not per chimney, so you’re never surprised by a “multi-flue upcharge” at the end.
When a Chelsea Homeowner Needs a Cap
If you can see daylight through the top of the flue from inside the attic or roof hatch, the cap is gone or failing. If you smell a musty odor from the fireplace after rain, water is likely pooling in the smoke chamber. Both are reason enough to call. We stock caps sized for the flue tiles and liners common in Chelsea’s older chimneys.
Materials and Fit
We install Olympia Chimney and Copperfield caps, both stainless and galvanized options. On exposed roof lines like those east of Broadway where wind comes off the Mystic River, we recommend stainless. It holds up better to salt air and ice. The cap gets mounted with mechanical fasteners, not silicone, and we photograph the finished install.
Chimney Cap Replacement in Chelsea
Chimney cap replacement in Chelsea usually follows one of two discoveries: a rusted-out cap found during a sweep, or water streaking down a flue that the old cap stopped covering years ago. We see this constantly on three-deckers where the original cap was installed with cheap galvanized steel and never checked after the first winter.
Replacing a cap runs $220 – $360 per flue in Chelsea when the old cap is standard-sized and the mounting surface is intact. If the crown underneath is cracked or spalled, that cost rises because the crown needs repair before a new cap can seat properly. We always check the crown before quoting a replacement, because mounting a new cap on a failing crown is wasted money.
Signs the Cap Is Failing
Rust flaking at the cap edges, a screen that sags into the flue, or a cap that has shifted off-center. Inside, you might notice water stains on the firebox walls or a drip sound after heavy rain. On a top-floor unit, that stain might show on the ceiling before you ever see the chimney.
Multi-Flue Replacement on Triple-Deckers
On a triple-decker with three flues that share one chimney chase, each flue gets its own cap. We quote and photograph each one separately. Replacing all three at once saves on trip charges and lets us check the entire chase for cracked mortar while the ladder is up.
Trusted Brands We Service in Chelsea
Our trucks carry DuraFlex liners, HeatShield resurfacing material, Olympia Chimney caps, and Copperfield flashing products, so we aren’t sending a runner to a supply house mid-job for common repairs. Chelsea’s older chimneys often need specific flue tile dimensions and liner diameters, and we keep the most common sizes on hand. When a flue liner is beyond saving, we line with DuraFlex. When the smoke chamber is cracked but structurally sound, HeatShield often lets us reline without demolition. You’ll see the exact product name on your written quote.
Common Chimney Repair Problems We See in Chelsea Homes
- Water entry through failed caps and flashing. On Chelsea’s exposed rooflines, wind-driven rain finds every gap. A missing cap or pulled flashing quietly rots the crown and smoke chamber, and by the time a stain shows inside, the damage is already several years old.
- Third-degree creosote glaze in flues that only get brushed. A brush cannot remove hardened tar glaze. We see this in Chelsea multifamily flues that haven’t had a proper camera inspection, and it is the kind of creosote that sustains a chimney fire.
- Restricted draft in shared or undersized flues. When a firebox, damper, or smoke chamber on a lower unit shares a flue with an added appliance, smoke and carbon monoxide can back into a lower-level apartment. This is a fix-it-now condition, not a schedule-it condition.
- Spalling brick crowns on older masonry chimneys. Chelsea’s freeze-thaw cycle works brick loose from the top down. Once the crown starts shedding, water gets behind the brick face, and the repair scope grows each season it is ignored.

FAQs About Chimney Repair in Chelsea
Every chimney in Chelsea should be inspected once a year, even if the fireplace hasn’t been used. The reason is simple: weather and time damage a chimney whether or not it burns wood. If you burn regularly in a triple-decker, inspections matter even more because several units share a single masonry structure. One cracked flue liner affects everyone in the building. Call (830) 251-4560 to schedule.
A Level 2 inspection covers everything visible and then goes further: we run a camera down each flue from the roof or firebox, check the crown, flashing, firebox, damper, and smoke chamber, and document every finding with photos. On a triple-decker, each flue gets its own camera pull and its own report. You’ll know exactly which flues are sound, which need work, and which can wait. We use the Level 2 protocol whenever a property changes hands, after a chimney fire, or when a flue has been taken out of service and brought back.
You can safely defer cosmetic spalling brick or minor mortar gaps that haven’t opened into the flue. What you can’t safely defer: a cracked flue liner, a failing cap letting water directly into the chase, pulled flashing at the roofline, or restricted draft that sends smoke or carbon monoxide into a unit. If we can’t say a repair can wait with a straight face, we won’t tell you it can. And when we say it can wait, we’ll tell you exactly what would change that answer. Call (830) 251-4560 and we’ll put it in writing.
Yes. We install and replace caps on single-flue and multi-flue chimneys throughout Chelsea, and we replace and repair roofline flashing. It’s common for a Chelsea homeowner to need both done in the same visit, because a failed cap and pulled flashing usually fail together. We quote both jobs separately, install them in one trip, and guarantee each for one full year. Call (830) 251-4560 for a written price before any work begins.
In most Chelsea homes, yes. A stainless DuraFlex liner can be pulled down an existing flue when the masonry structure is still sound, and that often avoids full demolition. If the flue has cracked mortar joints but the clay tiles are still intact, HeatShield resurfacing can seal and smooth the interior without removing the old liner. If the chimney structure itself is failing, a rebuild may be unavoidable, but we won’t recommend it until the camera shows us why. Call (830) 251-4560 for an exact quote.
