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 Somerville, MA
Chimney cleaning in Somerville, MA costs $189 to $329 for a standard sweep with a camera-scan inspection included. What makes Somerville different is the housing stock: thousands of triple-deckers built between 1880 and 1930, most with one shared brick chimney stack carrying three separate flues. Those flues were sized for coal and wood. They’re oversized for today’s high-efficiency gas appliances, and that mismatch is why Somerville chimneys build acidic deposits faster than typical New England homes. Call (980) 580-8641 for a written quote before any work starts.
Why Somerville Homes Are Different
Somerville’s triple-deckers define the chimney work we do here. A single chimney structure in Winter Hill or Prospect Hill typically contains two or three stacked terracotta flues, one per unit. Those flues were built for coal and wood stoves. Every fuel conversion since, coal to oil, then oil to high-efficiency gas, left each flue more oversized for the appliance it now serves. Oversized flues on low-BTU gas burners never get hot enough to push moisture out. The result is interior condensation that runs down the tile liner, carrying acidic byproducts into the mortar joints.
We regularly see flues in Somerville where one or two of the three have been abandoned. A unit switches to a direct-vent appliance, someone stuffs insulation in the old flue or caps it with a board, and the uncapped neighbors become open moisture channels. The shared brick stack deteriorates from the inside out. On top of that, Somerville winters bring dozens of freeze-thaw cycles that work on the soft 19th-century mortar and low-fired brick from the outside. Spalling brick and washed-out mortar joints are standard findings on sweeping appointments here, not exceptions.
Our Main Somerville Services
Two services come up more than any others when Somerville homeowners call: fireplace work and chimney caps or crowns. Both jobs are shaped by the city’s triple-decker construction and freeze-thaw cycles.
Fireplace Services in Somerville
Fireplaces in Somerville’s older homes are often original masonry fireboxes with decades of use behind them. The most common issues we find are cracked firebrick, failing dampers, and smoke chambers that were never parged properly when the home was built. A camera scan through the smoke chamber tells us what the firebox alone can’t. We document everything with photos and give you a written scope before any repair work begins. Whether it’s a gas log set, a wood-burning restoration, or troubleshooting smoke spillage into the unit, our Fireplace Services in Somerville page covers the details.
Chimney Cap & Crown in Somerville
Somerville’s freeze-thaw cycles make the crown the most vulnerable part of any chimney. Water gets into hairline cracks, freezes, expands, and turns small cracks into spalling brick and open mortar joints within a few seasons. A proper cap and crown job stops that cycle before it reaches the flue liners. We install stainless steel caps sized to each flue and rebuild crowns with a proper drip edge so water sheds away from the brick. See Chimney Cap & Crown in Somerville for full scope and pricing.

BeforeAfterChimney Sweep in Somerville
Chimney sweep in Somerville runs $189 to $329 for a standard job with a camera inspection included. The work here is defined by the housing stock: shared triple-decker chimneys with multiple oversized flues that collect acidic creosote-like deposits even when a unit is gas-only. We sweep every flue separately, not just the one you think you use, because in Somerville abandoning a flue without proper sealing is common and dangerous. Our Chimney Sweep service hub explains the full process.
Level 1 Inspection
Signs you need it
You use your fireplace or wood stove regularly and haven’t had the flue checked in over a year.
What it costs in Somerville
A Level 1 inspection in Somerville runs $189 to $249 when paired with a standard sweep.
How we do it
We check the accessible portions of the flue, firebox, damper, and exterior chimney, then give you a written report with photos.
Level 2 Inspection
Signs you need it
You just bought your Somerville home, changed fuel type, had a chimney fire, or experienced an earthquake or major storm.
What it costs in Somerville
A Level 2 camera-scan inspection in Somerville runs $329 to $429 depending on the number of flues in your stack.
How we do it
We run a camera down every flue, document liner condition and mortar joints, and deliver a photo record with the written report.
Creosote Removal
Signs you need it
You have a quarter-inch or more of buildup, or you smell a sharp, smoky odor near the fireplace in humid weather.
What it costs in Somerville
Creosote removal on a Somerville wood-burning flue runs $249 to $379, with Class III glazed creosote falling in the higher end.
How we do it
We use rotary brushes and chemical treatments appropriate to the creosote class, then camera-verify the flue is clean.
Annual Sweep
Signs you need it
It’s been 12 months or more since your last sweep, or you can see dark buildup on the damper or firebox walls.
What it costs in Somerville
An annual sweep in Somerville runs $189 to $249 for the first flue, with each additional flue in a shared stack adding $79 to $119.
How we do it
We sweep each flue with appropriately sized brushes, vacuum with HEPA filtration, and run a camera to confirm the result.
What Chimney Sweep Costs in Somerville
| Item | Typical range in Somerville |
|---|---|
| Level 1 inspection with sweep | $189 - $249 |
| Level 2 camera-scan inspection | $329 - $429 |
| Creosote removal (wood flue) | $249 - $379 |
How often should I get my Somerville chimney swept?
Every 12 months if you burn wood, and every 2 to 3 years for gas-only flues in Somerville. Triple-decker shared stacks can accumulate acidic deposits faster, so a camera check every couple of years is cheap insurance.
Do you sweep every flue in my triple-decker or just mine?
We sweep every flue in the shared stack. In Somerville, neighboring flues often have abandoned or uncapped openings that affect the entire structure. We inspect and document all of them, not just the one connected to your unit.
Chimney Repair in Somerville
Chimney repair in Somerville is driven by two forces: 130-year-old mortar joints and dozens of freeze-thaw cycles every winter. The soft, low-fired brick common in the city’s triple-deckers absorbs water, and when that water freezes, it spalls the brick face and washes mortar out of the joints. Repair here almost always means addressing both the visible damage and the water entry that caused it. Our Chimney Repair hub covers the full range of what we fix.
Mortar Repointing
Signs you need it
You can see eroded, crumbling, or missing mortar between bricks on your chimney, or you find sandy grit at the base after rain.
What it costs in Somerville
Mortar repointing in Somerville runs $800 to $1,900 for a typical triple-decker chimney stack, depending on access and extent.
How we do it
We grind out deteriorated mortar to a proper depth, match the original mortar composition, and tuckpoint every joint cleanly.
Flashing Repair
Signs you need it
You have water staining on ceilings or walls near the chimney, or you can see rusted, lifted, or missing flashing at the roofline.
What it costs in Somerville
Flashing repair in Somerville runs $450 to $950 for a typical roof-to-chimney junction with minor masonry prep included.
How we do it
We remove old flashing, install new step and counter flashing, seal properly, and document the finished job with photos.
Chimney Waterproofing
Signs you need it
Your brick absorbs water and stays dark after rain, or you see white efflorescence staining the chimney face.
What it costs in Somerville
Chimney waterproofing in Somerville runs $450 to $850 for a full stack, including cleaning and a breathable masonry sealer.
How we do it
We clean the brick, repair minor surface defects, and apply a vapor-permeable waterproofing agent that lets the chimney breathe.
What Chimney Repair Costs in Somerville
| Item | Typical range in Somerville |
|---|---|
| Mortar repointing (full stack) | $800 - $1,900 |
| Flashing repair | $450 - $950 |
| Chimney waterproofing | $450 - $850 |
Is spalling brick urgent or can it wait?
Spalling brick means water is getting in and freezing. It worsens every winter in Somerville. A few spalled faces can be addressed with a targeted repair, but ignoring it turns a $500 repair into a $3,000 rebuild within a few seasons.
Do I need an HOA or city permit for chimney repair in Somerville?
Most routine repairs like repointing and flashing don’t require a permit in Somerville. Full rebuilds or structural work may need city approval. We can tell you what applies to your specific job and provide documentation if your HOA asks.
Chimney Liner & Rebuild in Somerville
Chimney liner and rebuild work in Somerville is almost always tied to the same root cause: oversized flues that never reach proper operating temperature. Condensation from low-BTU gas appliances eats at terracotta tile liners, and once a liner cracks, heat and gases have a path to the brick and framing. In Somerville’s shared triple-decker stacks, one failed liner compromises the whole structure. Our Chimney Liner & Rebuild hub explains the options.
Stainless Steel Liner
Signs you need it
Your camera inspection shows cracked tiles, missing mortar joints, or your liner is the wrong size for your current appliance.
What it costs in Somerville
A stainless steel liner in Somerville runs $1,800 to $3,400 installed, depending on flue length and access.
How we do it
We measure the flue, pull a DuraFlex or Copperfield liner sized to the appliance, insulate as needed, and camera-verify the installation.
Liner Replacement
Signs you need it
You have visible tile pieces in the firebox, a failed Level 2 inspection, or gas appliance draft failure.
What it costs in Somerville
Full liner replacement in Somerville runs $2,200 to $4,800 including removal of the old liner and a new stainless system.
How we do it
We remove the deteriorated liner, prep the flue, install a properly sized stainless liner, and document the work with before-and-after photos.
Full Chimney Rebuild
Signs you need it
Your chimney has extensive spalling, structural cracks, a leaning stack, or crushing mortar joints throughout.
What it costs in Somerville
A full chimney rebuild from the roofline up in Somerville runs $6,500 to $14,000 depending on height, access, and the number of flues.
How we do it
We tear down to a stable point, rebuild with proper brick and mortar, install new liners as needed, and crown the top correctly.
What Chimney Liner & Rebuild Costs in Somerville
| Item | Typical range in Somerville |
|---|---|
| Stainless steel liner | $1,800 - $3,400 |
| Liner replacement (full) | $2,200 - $4,800 |
| Full chimney rebuild | $6,500 - $14,000 |
How do I know if my liner actually needs replacement?
You need a camera scan to know for sure. We never recommend liner replacement based on age alone. The camera shows cracked tiles, missing joints, or corrosion, and you get the photos before anyone asks you to spend a dollar.
Can you reline just one flue in a shared triple-decker chimney?
Yes. We can reline one flue while leaving the others intact, as long as the others are structurally sound and properly capped or connected to active appliances. In Somerville, we often find one active flue and two abandoned neighbors in the same stack.
Brands We Service in Somerville
We stock and install parts from Copperfield, DuraFlex, and HeatShield. In Somerville, we keep common liner sizes and cap components on our local trucks, so most repair and relining jobs need only one visit. See our brands for details.
