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 Boston, MA
Chimney cleaning in Boston typically costs $180-$320 for a standard sweep with a Level 1 inspection, and most jobs take under two hours. What makes Boston different from almost any other market is the housing stock: brick triple-deckers and brownstone row houses built between 1870 and 1930, many still running original unlined masonry flues that have never been properly evaluated. If you own one of these homes, call (980) 580-8641 for a written quote before anyone sets foot on your roof.
Why Boston Homes Are Different
Boston’s residential neighborhoods are dominated by brick triple-deckers and brownstone row houses built between roughly 1870 and 1930, most retaining their original unrelined masonry chimney stacks. In Dorchester, South Boston, Jamaica Plain, and Roxbury especially, a single chimney stack routinely serves multiple stacked residential units through several flues at once. That means the scope of a cleaning job here frequently involves coordinating access across two or three floors, identifying which flue belongs to which unit, and documenting conditions for landlords and tenants separately. The liability picture is more complex than in a single-family suburban market.
Massachusetts also has one of the highest rates of home heating oil use in the country. Boston sweeps disproportionately encounter century-old unlined masonry flues coated in sulfurous oil-soot deposits rather than wood creosote. Oil soot is acidic, sticky, and chemically different from wood creosote; it requires more aggressive mechanical removal and a different inspection lens. Layer on the salt-laden air off Boston Harbor, which accelerates mortar joint erosion, and the dozens of freeze-thaw crossings each winter, and you get chronic spalling, crown cracking, and liner degradation that inland New England cities simply don’t see at the same rate.
Our Main Boston Services
Most Boston homeowners call us first about two things: getting a fireplace back into safe working order, and protecting the top of the chimney from the harbor weather. Here is what each involves locally.
Fireplace Services in Boston
In Beacon Hill and Back Bay brownstones, decorative Victorian fireplaces were frequently sealed or converted to gas inserts in the 1950s through the 1970s without relining. When owners reopen them today, we often find bare rubble-masonry or collapsed clay-tile flues that are flatly non-compliant with Massachusetts 527 CMR fire code. That turns a routine cleaning call into a liner job before the fireplace can legally be used. We document everything with the camera and give you a written scope before any work starts. See Fireplace Services in Boston for the full breakdown.
Chimney Cap & Crown in Boston
Salt air off Boston Harbor accelerates mortar erosion at the crown, and the freeze-thaw cycle does the rest. A cracked crown lets water into the stack and the chase, which is how spalling brick and rusted dampers begin. We install Copperfield and Gelco caps sized to the flue, rebuild crowns with proper overhang and drip edge, and photograph the before and after as standard. Read the details on Chimney Cap & Crown in Boston.

BeforeAfterChimney Sweep in Boston
A chimney sweep in Boston on a triple-decker or brownstone is rarely a simple brush job. The oil-fired heating systems common across the city leave a sulfurous, acidic soot on flue walls, and the original unlined masonry flues in pre-1930 buildings need a different set of eyes than a modern terracotta or steel liner would. We run a full camera-scan inspection on every visit so you see exactly what was removed and what remains. That photo record is standard under Clause 4 of the Haven Standard, the same documentation practice we have kept on every job since 2009. For the full national scope of this work, see Chimney Sweep.
Level 1 Inspection
Signs you need it
You use the fireplace or heating appliance regularly and nothing has changed, but you want a baseline condition record before burning season.
What it costs in Boston
A Level 1 inspection in Boston runs $100-$160 when scheduled as a standalone visit, and it is included at no extra charge with a standard cleaning.
How we do it
We check the accessible portions of the flue, damper, firebox, and chimney exterior by visual means, and we photograph what we see so you have a record.
Level 2 Inspection
Signs you need it
You bought the house recently, changed fuel type, had a chimney fire, or the building changed hands or tenants.
What it costs in Boston
A Level 2 camera-scan inspection in Boston costs $200-$350, and it is the default standard we work to on first visits in pre-1930 housing.
How we do it
We send a camera down the full flue length, document every joint and offset, and deliver the footage with a written condition report.
Creosote Removal
Signs you need it
You burn wood and notice a tar-like glaze on the firebox walls or a strong, acrid smell even when the fire is out.
What it costs in Boston
Creosote removal in Boston runs $200-$300 for moderate buildup, with Class III glazed creosote starting at $350 and up depending on flue height.
How we do it
We run rotary chains or chemical treatment depending on the creosote class, then re-scan the flue to confirm the walls are clear.
Soot Removal
Signs you need it
Your oil-fired furnace or boiler vents through the chimney and you see dark, oily residue around the cleanout door or draft hood.
What it costs in Boston
Oil soot removal in Boston typically runs $200-$280, reflecting the heavier mechanical work and disposal than a wood-burning sweep.
How we do it
We use rotary brushes and vacuum extraction, then check the entire flue path by camera to confirm nothing was left behind.
Annual Sweep
Signs you need it
It has been more than a year since the last cleaning, or you burn more than one cord of wood per season.
What it costs in Boston
An annual sweep in Boston costs $180-$260 for a single flue, with a $60-$80 surcharge for each additional flue in the same stack.
How we do it
We brush the flue from top and bottom as needed, vacuum everything, and hand you a dated photo report of the clean flue walls.
What Chimney Sweep Costs in Boston
| Item | Typical range in Boston |
|---|---|
| Standard chimney sweep + Level 1 inspection | $180-$260 |
| Each additional flue in the same stack | $60-$80 |
| Level 2 camera-scan inspection (standalone) | $200-$350 |
Do I need a camera inspection with a routine sweep in Boston?
On a pre-1930 unlined masonry flue, yes. Oil soot and spalled mortar hide defects a brush cannot reveal. We include the camera scan and photo record on every visit.
How often should a triple-decker chimney in Boston be swept?
Annually for wood-burning flues, and every one to two years for oil-fired flues, which accumulate acidic soot faster than most homeowners expect.
Chimney Repair in Boston
Chimney repair in Boston is dominated by two forces: salt air off the harbor and a freeze-thaw cycle that runs dozens of times each winter. On a 19th-century brick row house in South End or Charlestown, that means mortar joints erode, brick faces spall, and crowns crack faster than anywhere inland. We identify the exact failed components by camera and hand you a written price before any work starts. For the full national breakdown, see Chimney Repair.
Mortar Repointing
Signs you need it
You can scrape crumbly mortar from between bricks with a fingernail, or you see hairline cracks running along the joints.
What it costs in Boston
Mortar repointing in Boston runs $18-$32 per square foot, with the higher end reflecting multi-story access on row-house stacks.
How we do it
We grind out the failed joint to the correct depth, pack in a lime-based mortar matched for the brick’s age, and tool it to the original profile.
Spalling Brick Repair
Signs you need it
Brick faces are popping off, leaving exposed, crumbling cores and piles of red dust at the base of the chimney.
What it costs in Boston
Spalling brick repair in Boston costs $300-$700 per affected section, depending on how many courses have failed and scaffold access.
How we do it
We remove the damaged brick to a solid substrate, replace them with matched or compatible units, and repoint the surrounding joints.
Chimney Waterproofing
Signs you need it
You see a dark, persistent damp stain on the chimney breast inside the house, or the brick looks saturated after rain.
What it costs in Boston
Chimney waterproofing in Boston runs $200-$400 for a full stack treatment, best applied after repairs so water never re-enters.
How we do it
We apply a vapor-permeable siloxane treatment to the masonry so the brick can still breathe while shedding water.
Flashing Repair
Signs you need it
You have stains on the ceiling directly around the chimney chase, or the step flashing has lifted away from the brick.
What it costs in Boston
Flashing repair in Boston typically runs $350-$700, with full replacement at $800-$1,500 where the existing metal is corroded through.
How we do it
We seat new metal into a reground mortar joint, seal the transition, and water-test before we come down.
Chimney Rebuilding
Signs you need it
The stack is leaning, the crown has separated, or the top several courses have lost structural integrity.
What it costs in Boston
A partial chimney rebuild in Boston starts at $2,000-$3,500, and a full stack rebuild runs $5,000-$8,000 depending on height and access.
How we do it
We dismantle to the sound masonry below the failure line, rebuild with matching brick, and install a new crown and flashing system.
What Chimney Repair Costs in Boston
| Item | Typical range in Boston |
|---|---|
| Mortar repointing | $18-$32 per sq ft |
| Spalling brick repair | $300-$700 per section |
| Flashing repair | $350-$700 |
Can chimney repair wait until spring in Boston?
Water-damage repairs cannot. Each freeze-thaw cycle widens existing cracks, so a repointing job deferred through winter often becomes a rebuild by April. Call us at (980) 580-8641 for an exact scope.
What is a reasonable price for repointing in Boston?
For a standard double-flue stack, $18-$32 per square foot is the honest range, with access and scaffolding driving the upper end. We put the price in writing before work starts.
Chimney Liner & Rebuild in Boston
Chimney liner and rebuild work in Boston is triggered most often by two local realities: the sealed-up Victorian fireplaces of Beacon Hill and Back Bay that were never relined, and the original rubble-masonry flues in triple-deckers that have deteriorated past any safe use. When a routine cleaning turns up a collapsed clay-tile flue or a bare masonry smoke path, Massachusetts 527 CMR code mandates a listed liner before the fireplace can be used legally. We install DuraFlex and HeatShield systems and document every step with the camera before, during, and after. The full national page is at Chimney Liner & Rebuild.
Stainless Steel Liner
Signs you need it
You are converting to a gas or oil appliance, or the existing clay tile is cracked and the appliance requires a listed UL 1777 liner.
What it costs in Boston
A stainless steel liner in Boston runs $1,800-$3,500 installed for a standard one-story or two-story flue, depending on diameter and access.
How we do it
We size the liner to the appliance’s BTU input and the existing flue dimensions, install it in one continuous section, and insulate where code requires.
Flexible Liner
Signs you need it
Your flue has offsets, a corbeled masonry smoke path, or a tight passage that makes a rigid liner impractical.
What it costs in Boston
A flexible liner in Boston runs $1,600-$3,200 installed, with the final price set by flue height and the number of offsets.
How we do it
We pull the liner through the full flue length, secure it at the top and bottom, and re-scan the interior to verify full seating.
Liner Replacement
Signs you need it
The existing liner is cracked, spalled, or missing sections entirely, and the camera footage shows it cannot be repaired.
What it costs in Boston
Liner replacement in Boston, including removal of the old liner and installation of a listed replacement, runs $2,000-$4,000.
How we do it
We remove the failed liner, inspect the masonry behind it, install the new listed system, and hand you before, during, and after photos.
Partial Rebuild
Signs you need it
The top courses of brick have failed from freeze-thaw spalling, but the lower stack remains structurally sound.
What it costs in Boston
A partial chimney rebuild in Boston runs $2,000-$3,500 for the top ten to fifteen courses, including a new crown.
How we do it
We dismantle to sound masonry, relay the courses with a compatible brick, set a new crown with proper overhang, and re-flash.
Full Chimney Rebuild
Signs you need it
The entire stack is compromised from spalling, leaning, or multiple failed repairs, and the structure cannot be safely reinforced.
What it costs in Boston
A full chimney rebuild in Boston runs $5,000-$8,000 on a standard triple-decker or row house, with the price climbing for access and height.
How we do it
We take the stack down to the roof line or below, rebuild with matching masonry, install new liners, crown, and flashing, and document every phase.
What Chimney Liner & Rebuild Costs in Boston
| Item | Typical range in Boston |
|---|---|
| Stainless steel liner | $1,800-$3,500 |
| Flexible liner | $1,600-$3,200 |
| Partial rebuild | $2,000-$3,500 |
Do I really need a new liner, or can I just keep using the fireplace?
If the camera shows a collapsed or missing liner, no. Massachusetts 527 CMR code forbids use of an unlined or failed flue, and running it risks combustion gas intrusion into living spaces. Call (980) 580-8641 and we will show you the footage before any work is quoted.
What actually happens if I skip a liner replacement in Boston?
Combustion gases leak into the masonry and can enter living spaces. Oil-fired systems produce acidic byproducts that eat through old mortar at an accelerated rate. The repair rarely gets cheaper by waiting.

Three things push a Boston quote toward the upper end: multi-flue stacks on triple-deckers where each flue is scoped separately, salt-damaged masonry that has been left exposed for multiple winters, and roof access that requires scaffolding rather than a ladder. Whatever the number, you get it in writing before any work starts, under Clause 1 of the Haven Standard.
