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.

AfterChimney Cleaning in Chelsea, MA
Chimney cleaning in Chelsea, MA typically costs $189-$389 for a standard sweep and is recommended annually for homes with wood-burning fireplaces or stoves. Chelsea’s dense housing stock of post-1908 brick triple-deckers and rowhouses means most chimneys here serve shared masonry stacks that are now approaching or exceeding 100 years old. That age, combined with salt-laden air from Chelsea Creek and the Mystic River, creates creosote accumulation and mortar deterioration patterns we see across the city every week. Call (980) 580-8641 for a written price before any work starts.
Why Chelsea Homes Are Different
Almost every chimney in Chelsea was rebuilt after the 1908 Great Chelsea Fire, which leveled most of the city and produced the dense triple-decker and brick rowhouse stock that still defines neighborhoods like Bellingham Square, Prattville, and Mill Hill. Those 1910s through 1930s masonry chimneys are now hitting 100 years old at roughly the same time, which means mortar joints across Chelsea are failing on a shared timeline rather than house by house.
The tidal exposure along Chelsea Creek and the Mystic River accelerates salt-driven spalling on exterior brick, and New England freeze-thaw cycles work into those salt-softened joints each winter. Inside the flue, decades of oil-to-gas heating conversions have left many Chelsea chimneys sized for equipment that is no longer there. An oversized flue runs cool, condensing moisture that binds with creosote and accelerates deposits in a way a properly sized liner would not.
What makes Chelsea genuinely different from a sweep in, say, Medford or Somerville is the multi-unit factor. Shared chimney chases serving two or three rental units mean a creosote load in one flue is not just one household’s problem. It is a building-wide fire and carbon monoxide risk, and it often sits behind locked tenant doors that complicate access and inspection.
Our Main Chelsea Services
Beyond chimney cleaning, Chelsea homeowners most often call us about fireplace services and chimney cap or crown work, both of which get shaped by the same aging brick and salt exposure that drives sweeps here.
Fireplace Services in Chelsea
Fireplace work in Chelsea often begins with the fireplace itself, not the flue above it. Gas inserts, pellet stoves, and wood-burning fireboxes in triple-deckers run into the same shared-flue complications we see everywhere in this city. We inspect the firebox, damper, and connection to the flue, then document everything with camera footage before recommending any work. For details on fireplace-specific services, see Fireplace Services in Chelsea.
Chimney Cap & Crown in Chelsea
The crown is the concrete slab at the top of the chimney, and in Chelsea it takes the full brunt of tidal salt air and freeze-thaw cycling. When a crown cracks, water gets into the masonry below and starts a spalling cycle that worsens every winter. Replacement caps and crowns also keep rain, birds, and debris out of flues that may serve multiple units. We stock cap and crown materials for Chelsea jobs and document the before and after. See Chimney Cap & Crown in Chelsea for more.

BeforeAfterChimney Cleaning & Sweep in Chelsea
Chimney cleaning and sweep in Chelsea starts with the reality that most flues here are a century old, shared by multiple units, and exposed to salt air that accelerates creosote bonding. We sweep every flue with a camera inspection included, which means you see exactly what was removed and what condition the liner is in before we leave. The full scope of our Chimney Cleaning & Sweep service is built around documenting what we find, not just clearing what we can reach.
Level 1 Inspection
Signs you need it
You burn wood regularly and have not had a documented inspection this year, or you just bought a Chelsea triple-decker and want a baseline on the flue condition.
What it costs in Chelsea
A Level 1 inspection in Chelsea typically runs $129-$199 when paired with a cleaning, and it is included with most standard sweeps.
How we do it
We inspect the accessible portions of the flue, check for creosote class and obstructions, and hand you a written condition summary with photos.
Level 2 Inspection
Signs you need it
You have had a chimney fire, are changing fuel type, or are buying or selling a multi-unit Chelsea building where the flue condition must be documented.
What it costs in Chelsea
A Level 2 camera inspection in Chelsea typically runs $249-$449, with the higher end covering multiple flues in one shared chase.
How we do it
We run a camera the full length of the flue, document every joint and liner surface, and provide a photo record as required by our inspection standard.
Creosote Removal
Signs you need it
You smell a strong tar odor near the fireplace or your sweep report shows Class II or Class III creosote, which is common in Chelsea’s cool-running oversized flues.
What it costs in Chelsea
Creosote removal in Chelsea typically runs $189-$389 for standard mechanical removal, with heavy Class III glazing reaching $600-$1,100 for chemical treatment plus mechanical removal.
How we do it
We use rotary brushes and inspection camera checks between passes, then document the final creosote class before we call the flue clear.
Annual Sweep
Signs you need it
You use the fireplace or stove every season, or you are a Chelsea landlord with a shared chase where NFPA 211 calls for annual inspection and cleaning as needed.
What it costs in Chelsea
An annual sweep in Chelsea typically runs $189-$289 for a single flue, with multi-flue shared chases priced per flue and documented in writing before we start.
How we do it
We lay drop cloths, run brushes from the roof or firebox, vacuum the full system, and leave you a photo record plus a written condition note on the liner.
What Chimney Cleaning & Sweep Costs in Chelsea
| Item | Typical range in Chelsea |
|---|---|
| Annual sweep (single flue) | $189-$289 |
| Level 2 camera inspection | $249-$449 |
| Class III creosote removal | $600-$1,100 |
How often should a chimney be swept in Chelsea?
Every year if you burn wood regularly, according to NFPA 211. Chelsea’s salt air and oversized flues can accelerate creosote bonding, so a camera check each season catches liner damage before it becomes a repair.
Do I need a Level 2 inspection on a Chelsea triple-decker?
Yes, especially for multi-unit buildings. A Level 2 camera inspection documents each flue in the shared chase so one tenant’s liner failure does not become a building-wide carbon monoxide event. Call (980) 580-8641 to schedule.
Chimney Repair in Chelsea
Chimney repair in Chelsea is usually masonry work first and liner work second, because the salt air off Chelsea Creek and the Mystic River eats mortar joints faster than inland towns. Repointing, spalling brick replacement, and crown repair are the highest-volume repairs we quote in this city, and most jobs involve a shared chase where access and documentation matter as much as the mortar mix. Our Chimney Repair work always starts with a written price and a camera record of what is failing.
Mortar Repointing
Signs you need it
Mortar joints are recessed, crumbling, or you can scrape them out with a flathead screwdriver near the roofline of your Chelsea triple-decker.
What it costs in Chelsea
Mortar repointing in Chelsea typically runs $600-$1,800 for partial work and $2,500-$5,000 for a full chimney repoint, depending on access and how many stories we are working.
How we do it
We grind out failed joints to sound mortar, pack in a salt-resistant mix matched to the historic brick, and document the repair area before and after.
Spalling Brick Repair
Signs you need it
Brick faces are popping off or flaking, especially on the windward side facing the creek, leaving pitted surfaces and exposed masonry.
What it costs in Chelsea
Spalling brick repair in Chelsea typically runs $800-$2,500 for isolated replacement and $2,500-$5,000 for larger structural repairs with scaffolding.
How we do it
We cut out compromised brick, install replacements that match the original 1910s-1930s Chelsea stock, and seal the surrounding joints to slow further salt attack.
Chimney Waterproofing
Signs you need it
You see efflorescence, damp spots, or visible water staining on interior brick around the chimney chase after storms or snowmelt.
What it costs in Chelsea
Chimney waterproofing in Chelsea typically runs $400-$1,000 for a single chimney, depending on height and surface area.
How we do it
We apply a vapor-permeable masonry sealant that lets moisture escape while blocking salt-laden rain from working into the joints.
What Chimney Repair Costs in Chelsea
| Item | Typical range in Chelsea |
|---|---|
| Full chimney repoint | $2,500-$5,000 |
| Spalling brick repair | $800-$2,500 |
| Chimney waterproofing | $400-$1,000 |
Do I need a permit for chimney repair in Chelsea?
Structural repairs like rebuilding usually require a Chelsea building permit, which we can advise on as part of your written scope. Mortar repointing and minor brick replacement generally do not, but we confirm for each building before work starts.
How long does chimney repair take in Chelsea?
Most repointing and spalling repairs finish in one to three days. Larger rebuilds with scaffolding on a three-story Chelsea triple-decker can run a week or more. We give you a written timeline with the price before any work begins.
Chimney Liner & Rebuild in Chelsea
Chimney liner and rebuild work in Chelsea is often the endpoint of decades of oil-to-gas conversions, tenant-added heating appliances, and salt-driven masonry failure. When a flue in a shared chase has cracked or the chimney above the roofline has spalled past saving, we replace or rebuild with materials from Olympia Chimney, Gelco, and Copperfield, sourced through our buying network to keep Chelsea prices honest. See our full Chimney Liner & Rebuild service for the detailed scope.
Stainless Steel Liner
Signs you need it
Your camera inspection shows cracked flue tiles, gaps between sections, or a liner sized wrong for your current gas or oil appliance.
What it costs in Chelsea
A stainless steel liner installation in Chelsea typically runs $2,500-$5,000 for a single flue in a standard two- or three-story building.
How we do it
We measure the flue precisely, drop an Olympia or Gelco liner sized to the connected appliance, insulate as needed, and document the full run with camera footage.
Liner Replacement
Signs you need it
Your existing clay liner is spalling into the flue, your inspection report notes misaligned sections, or you are converting fuel and the current liner cannot handle the change.
What it costs in Chelsea
Liner replacement in Chelsea typically runs $2,500-$5,000 for a standard replacement and $5,000-$9,000 when the chase requires significant prep or partial rebuilding.
How we do it
We remove or bypass the failed liner, install a new stainless system, and verify the full run by camera before signing the job complete.
Full Chimney Rebuild
Signs you need it
The chimney above the roofline is visibly leaning, the masonry is fractured through multiple courses, or a structural report calls for reconstruction.
What it costs in Chelsea
A full chimney rebuild in Chelsea typically runs $8,000-$15,000 for an above-roofline rebuild on a typical triple-decker, with full chase rebuilds running $15,000-$30,000.
How we do it
We tear down to sound structure, rebuild with a new liner and Copperfield cap system, and document every stage so the finished chase meets current code.
What Chimney Liner & Rebuild Costs in Chelsea
| Item | Typical range in Chelsea |
|---|---|
| Stainless steel liner installation | $2,500-$5,000 |
| Full above-roofline rebuild | $8,000-$15,000 |
| Full chase rebuild | $15,000-$30,000 |
Do I really need a new liner in my Chelsea home?
Only if the camera shows cracked or misaligned sections, or the liner is sized wrong for the connected appliance. We do not recommend liner replacement without photo evidence you can see for yourself. Call (980) 580-8641 for a documented inspection.
Can tenant-added appliances affect my Chelsea chimney liner?
Yes. We regularly find triple-decker tenants added gas inserts or pellet stoves to separate flues without coordinated sizing, which can leave liners running cool and condensing. A camera inspection maps what each flue actually serves now.
Brands We Service in Chelsea
We install and service liners, caps, and masonry products from Gelco, Olympia Chimney, Famco, and Copperfield, with common Chelsea sizes stocked for faster turnaround on triple-decker chases. See our brands for the full parts list and warranty details.
