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.
Fast, Reliable Chimney Cleaning & Sweep Across Cambridge
A typical chimney cleaning and Level 2 inspection in Cambridge runs $280-$420, and most appointments are scheduled within a week of your call. Our crews serve Cambridge directly from our Boston office, with same-week availability through most of the year except peak pre-winter weeks in October and November.
We’ve worked on Cambridge chimneys since 2009, and the pattern is consistent: triple-decker stacks on streets like Hampshire, Broadway, and Cambridge Street that were built for coal heat now vent modern gas appliances into oversized, often unlined flues. That mismatch is where most chimney problems in this city start. Our Chimney Cleaning & Sweep team documents every flue with a camera before recommending anything, and we deliver a written price before any work begins. Call (781) 649-9326 to book.

Our local knowledge runs deep. We know which Cambridgeport blocks have the heaviest swift activity in spring, which East Cambridge triple-deckers share stacks across three units with mixed appliance types, and how the Charles River’s ambient moisture accelerates mortar decay on already-aged brick. That context changes what we look for and how we report it.
Our Chimney Cleaning & Sweep Services in Cambridge

Level 1 Inspection
A Level 1 inspection is a visual examination of the readily accessible portions of your chimney and appliance connection. In Cambridge, this is appropriate for chimneys that have been regularly maintained and are continuing in service without changes to the appliance or fuel type. We check the exterior for spalling brick, damaged flashing, and crown integrity, then examine the firebox and smoke chamber from below. Most Level 1 inspections in Cambridge run $180-$260. If we spot creosote buildup beyond first-degree or any structural concern, we’ll recommend a Level 2 camera inspection before proceeding with cleaning.

Level 2 Inspection
Level 2 is our standard for every Cambridge property we haven’t serviced before, and it’s required by NFPA 211 whenever a property changes hands, an appliance is replaced, or a chimney has experienced an event like a chimney fire or seismic impact. We run a camera the full length of every flue, documenting liner condition, mortar joint integrity, creosote classification, and any obstructions. In Cambridge’s triple-deckers, this often reveals what a ground-floor visual inspection cannot: a third-floor flue with deteriorated clay tiles, an abandoned flue housing a swift nest, or a gas-appliance flue venting into an unlined coal-era stack with condensation damage hidden mid-flue. Clause 4 of the Haven Standard requires this photo record on every job. Level 2 inspections in Cambridge typically cost $280-$420.

Creosote Removal
Cambridge’s extended heating season, five to six months of regular appliance use, produces creosote accumulation that ranges from light, brushable first-degree deposits to hardened, glazed third-degree buildup that requires rotary removal and chemical treatment. First-degree creosote, soft and flaky, removes with standard sweeping and runs $220-$320 in Cambridge. Third-degree glazed creosote, common in chimneys that haven’t been swept in multiple seasons, requires more intensive work and typically costs $380-$580. We classify what we find before quoting, and we show you the camera footage that supports the classification. No guesswork, no surprises after we start.

Soot Removal
Soot accumulation from oil and gas appliances is different from wood-burning creosote: finer, more acidic, and more likely to indicate incomplete combustion or draft problems. In Cambridge’s older triple-deckers, soot-heavy flues often signal that a modern high-efficiency appliance is venting into an oversized, unlined stack with inadequate draft. We remove the soot, document the flue condition, and flag any combustion or ventilation concerns for follow-up. Standard soot removal in Cambridge runs $200-$300, with camera inspection included.

AfterTrusted Brands We Service in Cambridge
We source materials through Haven’s buying network to keep customer prices honest, stocking flue liners from DuraFlex, crown repair compounds from HeatShield, and caps and dampers from Famco and Copperfield. For Cambridge customers, this means replacement parts that match your existing system are typically available without multi-week special orders. When a Cambridgeport triple-decker needs a liner sized for a converted gas boiler or an East Cambridge rowhouse needs a custom cap to handle Charles River wind exposure, we measure, spec, and install from inventory we’ve already vetted.
Common Chimney Cleaning & Sweep Problems We See in Cambridge Homes

- Shared triple-decker stacks with mixed active and abandoned flues. One 12-inch unlined flue vents a ground-floor gas boiler while the second and third-floor flues sit open, unused, and uninspected. Deferred maintenance on any unit affects draft and safety for the entire building.
- Chimney swift occupation in abandoned flues. These migratory birds nest in Cambridgeport and East Cambridge chimneys from May through October, and active nests are federally protected. A crew that sweeps without first checking for swifts risks a mid-job stop and a federal violation.
- Freeze-thaw mortar spalling accelerated by Charles River moisture. Cambridge’s chimneys endure dozens of freeze-thaw cycles each winter, with ambient river moisture wicking into century-old brick and popping mortar joints faster than inland suburbs see.
- Upsold relines on flues that only need cleaning and spot repair. An unlined clay-tile flue with first-degree creosote and minor spalling doesn’t automatically need a full reline. We show you the camera evidence and quote only what the condition supports.

On a three-story triple-decker in Cambridgeport, our tech ran a Level 2 inspection with a camera and found the shared stack had one active gas-appliance flue and two abandoned open flues, one with a chimney swift nest. We waited until November to sweep, then used a HeatShield flue liner in the gas flue and rebuilt the spalling chimney crown and replaced the chimney cap while leaving the swift flue undisturbed. The building’s draft and mortar issues were resolved without disturbing the protected nest or over-selling unneeded repairs.

FAQs - Chimney Cleaning & Sweep in Cambridge

Your building was constructed between 1890 and 1920 with one brick chimney stack serving all three floors, each with its own flue sized for coal or wood heat. As units converted to modern gas or oil appliances, many landlords abandoned the upper flues rather than maintain them, leaving one active flue and two open, unlined shafts that collect moisture, debris, and sometimes chimney swifts. We inspect all three flues during a Level 2 camera scan and recommend sealing or capping abandoned flues to prevent water damage and wildlife entry. Call (781) 649-9326 for an exact quote; estimates are free.
No, not between May and October. Chimney swifts are federally protected under the Migratory Bird Treaty Act, and active nests cannot legally be disturbed. We inspect for swift occupation before scheduling any sweep in Cambridgeport or East Cambridge, and if we find an active nest, we reschedule for November or later. This is standard practice for our Cambridge work, not an exception. Call (781) 649-9326 to book a pre-sweep inspection; estimates are free.
First-degree creosote is soft, flaky, and brushes away with standard sweeping; it’s what we expect from annual maintenance. Third-degree creosote is hardened, glazed, and tar-like, requiring rotary tools and sometimes chemical treatment to remove. In Cambridge’s extended heating season, third-degree buildup is common in chimneys that haven’t been swept in two or more years, and it significantly increases chimney fire risk. We classify what we find with camera evidence and quote accordingly before starting work. Call (781) 649-9326 for an inspection; estimates are free.
No. Clause 4 of the Haven Standard requires a documented photo record on every job, and we do not recommend liners, crowns, caps, or any repair without camera evidence you can see for yourself. Many Cambridge triple-deckers have unlined flues that only need cleaning and minor mortar repair, not a full reline. We show you the condition, explain what it means, and let you decide. Free Second Opinion on any competitor’s written quote. Call (781) 649-9326.
Cambridge temperatures cross 32°F dozens of times each winter, causing water trapped in mortar joints to expand and contract, which spalls brick and cracks crowns. Proximity to the Charles River adds persistent ambient moisture that wicks into aging masonry, accelerating deterioration beyond what inland Massachusetts cities experience. We inspect crown and flashing condition during every Level 2 scan and document cracks, pooling, or separation with photos. Repair recommendations are based on what we can show you, not age alone. Call (781) 649-9326 for an inspection; estimates are free.
