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.
Chimney Cleaning in Cambridge, MA
Chimney cleaning in Cambridge, MA typically costs between $189 and $349 for a standard sweep with a Level 1 inspection, though the city’s pre-1920s housing stock regularly pushes jobs into the $249 to $449 range when multiple flues are involved. Most Cambridge chimneys we open up were built for coal, not modern gas appliances, so what looks like a routine cleaning often turns into identifying which of two or three flues in a single stack actually vents what. Call (980) 580-8641 and we’ll give you a written price before anyone sets foot on your roof.
Why Cambridge Homes Are Different
Cambridge’s residential buildings date overwhelmingly from 1880 to 1930. Wood-frame triple-deckers and attached rowhouses dominate East Cambridge, Cambridgeport, and Mid-Cambridge, and a large share still run their original multi-flue brick stacks with clay tile liners set in coal-era lime mortar. That mortar has been failing for decades, and the city’s coastal New England climate does not help. Hard freeze-thaw cycles from November through March work water into hairline cracks, where it expands and spalls the soft aged brick. Damp air off the Charles River and Massachusetts Bay adds another layer: moss and efflorescence grow on chimney exteriors, which is usually the first visible sign that moisture has been moving through the masonry for years.
What makes Cambridge genuinely different from the suburbs is the multi-unit factor. A single 1900-era chimney stack commonly contains two to four separate flues originally built for coal stoves. Today one flue might be capped and abandoned, another venting a Category I gas boiler, and a third serving a wood-burning fireplace in a third-floor rental unit. Sweeps here have to identify each flue, check for cross-contamination between tenant units, and document everything carefully because landlord liability questions are not theoretical. In North Cambridge and the Avon Hill area, where converted mansions became condominiums, we routinely find that no one knows which flue belongs to which unit until we camera-scan them. That is why every Emberly Chimney Cleaners visit includes a documented photo record under Haven Standard Clause 4, the same practice we have run continuously since 2009.
Our Main Cambridge Services
Chimney cleaning is the service most Cambridge homeowners call about first, but two related jobs come up constantly in this housing stock. Here is what each involves locally.
Fireplace Services in Cambridge
Cambridge fireplaces in pre-1930 rowhouses and triple-deckers often sit on flues that were never designed for modern use. We see shallow fireboxes, missing dampers, and smoke chambers with corbeled brick that traps creosote in pockets a brush cannot reach. A Fireplace Services in Cambridge visit includes a camera scan of the full flue path, a written condition report on the firebox and damper, and a straight answer about whether the fireplace is safe to use as-is or needs liner work before the next burn.

Chimney Cap & Crown in Cambridge
Cambridge’s freeze-thaw cycle punishes chimney crowns more than almost any other component. The flat mortar crowns on 1920s-era rowhouses crack within a few seasons, letting water run down the brick and into the flue. A Chimney Cap & Crown in Cambridge job starts with a camera inspection to determine if water has already reached the liner, then a written recommendation for either a crown reseal or a full cast-in-place replacement, plus a properly sized cap matched to the flues in your stack.

Before
AfterChimney Sweep in Cambridge

Chimney cleaning in Cambridge is rarely a one-flue job. In a triple-decker built in 1910, a single stack may carry an active gas flue, an abandoned coal flue, and an active wood flue, and each has to be identified before any brushes go down. Creosote accumulation in Cambridge runs heavier than average because the city’s damp coastal air keeps flue walls cooler, which condenses smoke faster. Our full Chimney Sweep service starts with flue identification, then moves to mechanical brushing, and always ends with a camera scan so you can see the result yourself.
Level 2 Inspection
Signs you need it
You need a Level 2 inspection whenever a property changes hands, after a chimney fire, or before firing up a fireplace that has been dormant through multiple Cambridge winters with no record of prior service.
What it costs in Cambridge
A Level 2 inspection in Cambridge typically runs $249 to $449 depending on flue count and whether rooftop access requires staging on a steep rowhouse roof.
How we do it
We run a closed-circuit camera the full length of every flue in the stack, photograph the interior from crown to smoke chamber, and hand you a written report with images before we leave.
Creosote Removal
Signs you need it
If you see shiny, tar-like glaze inside the flue, smell a sharp campfire odor in the house during humid Cambridge summer days, or hear a crackling sound from the chimney during burns, you are dealing with Class II or Class III creosote, which a standard brush alone will not lift.
What it costs in Cambridge
Creosote removal in Cambridge runs $249 to $449 when rotary chains and chemical treatment are needed for glazed, tar-like buildup.
How we do it
We run rotary chains to break the glaze, follow with a chemical treatment to degrade the residue, and then camera-scan the flue to confirm the creosote is cleared to an acceptable level.
Annual Sweep
Signs you need it
You need an annual sweep if you burn wood in a Cambridge fireplace more than a couple times a season, or if this is the first service the chimney has had since you bought the house.
What it costs in Cambridge
An annual sweep in Cambridge with a Level 1 inspection runs $189 to $349 for a single flue, with multi-flue rowhouse stacks priced per additional flue.
How we do it
We identify each flue, mechanically brush from the roof or firebox, remove soot and creosote from the smoke chamber and damper area, then run a camera scan and hand you the photo record.
What Chimney Sweep Costs in Cambridge
| Item | Typical range in Cambridge |
|---|---|
| Standard sweep with Level 1 inspection | $189 - $349 |
| Creosote removal with rotary treatment | $249 - $449 |
| Level 2 camera inspection | $249 - $449 |
How often should a chimney be swept in Cambridge?
Once a year if you burn wood, even occasionally. Cambridge’s coastal damp condenses creosote faster than inland homes, and multi-flue stacks hide buildup between flues until it becomes a fire hazard.
Do I need a separate sweep for each flue in my Cambridge rowhouse?
Yes. Each active flue is swept and inspected individually, and the price reflects that. We identify all flues first, tell you which are active, and quote each one in writing before work begins.
Chimney Repair in Cambridge

Chimney repair in Cambridge is driven by freeze-thaw cycles and deferred maintenance on rental properties. Soft late-19th-century brick absorbs water all winter, freezes, and spalls, leaving open mortar joints that let more water in every spring. By the time we camera-scan a triple-decker flue in East Cambridge, we usually find spalled liner sections that have been uninspected for decades. Our Chimney Repair work starts with a camera scan, not a guess, so you see exactly what is broken before you pay to fix it.
Mortar Repointing
Signs you need it
If you can scrape mortar out of chimney joints with a fingertip or see missing mortar lines from the ground, the joints are open and water is moving through the stack.
What it costs in Cambridge
Mortar repointing in Cambridge runs $800 to $1,800 for a standard rowhouse stack, depending on access and how much joint depth needs to be raked out.
How we do it
We rake out failed mortar to a consistent depth, match the original lime-based mortar so the brick can still breathe, and tool the joints flush to shed water properly.
Flashing Repair
Signs you need it
Water staining on ceiling drywall near the chimney, or visible gaps between roof flashing and brick, means the flashing has pulled away and is letting Cambridge rain straight into the roof deck.
What it costs in Cambridge
Flashing repair in Cambridge typically runs $450 to $1,200 for a two-flue rowhouse chimney with standard step and counter flashing.
How we do it
We strip the old flashing, install new step and counter flashing cut tight to the brick, and seal the transition with a polymer sealant that tolerates Cambridge freeze-thaw movement.
What Chimney Repair Costs in Cambridge
| Item | Typical range in Cambridge |
|---|---|
| Mortar repointing | $800 - $1,800 |
| Flashing repair | $450 - $1,200 |
| Spalling brick replacement | $1,200 - $3,000 |
How do I know if my Cambridge chimney needs repair or just cleaning?
You do not, and neither does anyone looking from the ground. A camera scan shows spalling, open joints, and liner damage plainly. We quote only what the images show.
Can a Cambridge rowhouse chimney be repaired while renters are in the building?
Yes. We coordinate with landlords and tenants, work from the roof where possible, and document each flue we touch. Multi-unit stacks are standard for us here.
Chimney Liner & Rebuild in Cambridge

Chimney liner and rebuild work in Cambridge is usually about what is inside a shared stack more than the bricks you can see. Original clay tile liners in 1890 to 1920 rowhouses have cracked under a century of heat and freeze-thaw, and many conversions from coal to gas left oversized liners that now vent appliances inefficiently. A partially lined or unlined chase with two active flues and one abandoned coal flue fails both Cambridge building code and NFPA 211 at the same time. Our Chimney Liner & Rebuild service handles liner replacement, stainless steel installs, and partial or full rebuilds, quoted in writing before any material is ordered.
Stainless Steel Liner
Signs you need it
If your camera scan shows cracked clay tiles, missing mortar between tile sections, or an unlined brick flue actively venting a gas appliance, you need a stainless liner to carry exhaust safely.
What it costs in Cambridge
A stainless steel liner install in Cambridge typically runs $2,500 to $5,000 per flue depending on height, roof access, and whether insulation is required.
How we do it
We size the liner to the appliance and the flue, insulate where code requires, lower it from the crown, and connect it through a properly sealed top plate and cap.
Partial Rebuild
Signs you need it
When the top five to ten courses of brick above the roofline are spalled, loose, or leaning, a partial rebuild is usually cheaper than a full stack replacement and stops water before it reaches the roof.
What it costs in Cambridge
A partial rebuild in Cambridge runs $2,000 to $5,500 for a standard rowhouse stack, including brick match, new mortar, and a poured crown.
How we do it
We dismantle the damaged upper courses, match brick as closely as the century-old stock allows, rebuild with proper lime mortar, and pour a new crown with a drip edge.
What Chimney Liner & Rebuild Costs in Cambridge
| Item | Typical range in Cambridge |
|---|---|
| Stainless steel liner install | $2,500 - $5,000 |
| Partial rebuild | $2,000 - $5,500 |
| Full chimney rebuild | $8,000 - $18,000 |
Do I really need a new liner if my Cambridge chimney looks fine from the outside?
The outside condition tells you nothing about the inside. We routinely camera-scan Cambridge stacks that look perfect from the street and find cracked clay liners venting gas into walls. Ask for images first.
Can a full chimney rebuild be spread over two seasons?
Sometimes, but we do not recommend leaving an open stack through a Cambridge winter. Freeze-thaw does more damage to an exposed chimney in one season than in five years of normal wear.

We install and service liners and components from our brands including DuraFlex stainless systems, HeatShield resurfacing products, and Olympia Chimney caps and dampers.

What pushes price up in Cambridge is almost always access and flue count. A steep rowhouse roof with no staging point and a three-flue stack costs more than a single-flue colonial on flat ground, and we quote that reality in writing before any work starts. Nobody from Emberly Chimney Cleaners will ever ask you to commit without a written price, a written scope, and a written warranty in your hand under Haven Standard Clause 1.
