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.

AfterTrusted Chimney Cleaning & Sweep for Cambridge Homeowners
Chimney cleaning and sweep in Cambridge, MA typically costs $189-$389 for a standard service, with Level 2 camera inspections running $289-$489 depending on flue accessibility and creosote buildup severity. Level Two Chimney Cambridge completes most sweeps in 60-90 minutes and delivers a written price before any work begins. Call (857) 309-1908 for a free estimate with no obligation.
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and every single one left with a written scope, written price, and documented photo record under Clause 4 of the Haven Standard. Cambridge’s dense housing stock, from triple-deckers in Inman Square to the brick row houses of Harvard Square and the mid-century splits off Concord Avenue, presents specific challenges: narrow flues, shared chimney structures, and heating systems that run hard from October through April. The freeze-thaw cycles here are brutal on masonry, and the older oil-to-gas conversions common in Porter Square and North Cambridge often leave incompatible liner sizes that collect condensation and accelerated creosote.
Corrine Halstead and our team don’t guess at what’s happening inside your flue. We run a camera down every chimney we sweep, document what we find, and show you the footage before we quote any additional work. If you don’t need a repair, we’ll say so plainly. If you do, you’ll see exactly why.
What Our Chimney Cleaning & Sweep Service Includes
Level 1 Inspection
A Level 1 inspection is the baseline visual examination required annually for chimneys in regular use without changes to the appliance or fuel type. We inspect readily accessible portions of the chimney exterior, interior, and connecting appliances for soundness, freedom from deposits, and correct clearances. In Cambridge, where many homeowners in neighborhoods like East Cambridge and Cambridgeport rent out basement or in-law units with separate heating systems, a Level 1 inspection often reveals that the secondary flue hasn’t been examined in years.
Level 2 Inspection
A Level 2 inspection is mandatory when you’ve changed your heating appliance, relined your flue, experienced a chimney fire, or are preparing to sell your home. This is where Level Two Chimney Cambridge built its name: we lower a high-resolution camera the full length of the flue to examine the liner surface, mortar joints, and any offsets or transitions. Clause 4 of the Haven Standard requires this photo record on every job, a practice we started in 2009. The camera finds what a flashlight glance misses: cracked clay tile liners in 1920s triple-deckers, deteriorating stainless steel in 1980s inserts, and the gaping mortar voids that develop where Cambridge’s thermal cycling stresses chimney structures.
Creosote Removal
Creosote is the tar-like combustion byproduct that accumulates on flue walls, and it comes in three classes. Class I is flaky soot we brush away easily. Class II is crunchy and requires mechanical action. Class III is glazed, hardened, and highly combustible, often requiring chemical treatment before removal. Cambridge’s older masonry chimneys, especially those venting modern efficient appliances that send cooler exhaust up the flue, are prone to Class III buildup. We identify the creosote class during camera inspection and specify the creosote removal method in your written quote before we start.
Soot Removal
Soot accumulation reduces draft efficiency and can recirculate fine particulates into living spaces. Our soot removal service uses HEPA-contained vacuum systems and rotary brushes sized to your flue diameter. In Cambridge’s tighter homes, particularly the renovated Victorians in Mid-Cambridge where air sealing has improved dramatically, proper soot containment matters more than ever. We protect your floors and furnishings with drop cloths and seal the firebox before we begin.
Annual Sweep
The National Fire Protection Association recommends annual chimney inspection and cleaning for all solid-fuel appliances, and every other year for gas systems in heavy use. Our annual sweep in Cambridge is scheduled before burning season, typically September through early November, though we work year-round. Each annual service includes the camera inspection, creosote and soot removal, a written condition report, and documented photos archived under your address for future comparison. We text you a reminder when your anniversary approaches.
Fireplace Cleaning
Fireplace cleaning addresses the firebox, smoke chamber, damper assembly, and hearth area, not just the flue above. The smoke chamber, the angled area above the damper that funnels smoke into the flue, is where many Cambridge chimney fires begin, especially in shallow Rumford-style fireplaces common in pre-war construction. We inspect the smoke chamber for corbelled brick, degraded parging, and proper clearance to combustibles. Our fireplace cleaning includes damper lubrication and adjustment, ash removal, and recommendations for fireback or grate sizing if we see inefficient burn patterns.

Brands We Service for Chimney Cleaning & Sweep
We regularly service and stock parts for DuraFlex stainless steel liner systems, which we encounter frequently in Cambridge’s gas conversions where flexible liners navigate offset flues in triple-decker walls. DuraFlex’s corrugated design allows tight bends without compromising draft, but those corrugations also trap condensation in our freeze-thaw climate if not properly insulated. We’ve installed and maintained hundreds of DuraFlex runs and keep common diameters and termination caps on our trucks.
HeatShield cerfractory flue liner resurfacing is another specialty. For Cambridge homeowners with sound clay tile liners showing minor gaps or spalling, HeatShield can restore a smooth, insulated flue surface without full liner replacement. We are certified applicators and have completed HeatShield restorations in homes from Brattle Street to Broadway. Whether your system uses DuraFlex, HeatShield, or any other make, we can inspect, clean, and repair it. Our materials come through the Haven buying network, sourced specifically to keep customer prices honest.
BeforeAfterSigns You Need Chimney Cleaning & Sweep Right Now
- Smoke backing up into the room. If your fireplace or stove pushes smoke into the living space instead of up the flue, you likely have a blockage, creosote obstruction, or damper failure. In Cambridge’s tightly sealed modern renovations, negative pressure can compound draft problems. Don’t burn again until we’ve camera-inspected the flue.
- Strong, acrid odors from the fireplace in warm weather. That sharp smell when the weather turns humid is creosote off-gassing. It means significant buildup is present, and it’s often the first warning before more serious problems develop. The odor is particularly noticeable in Cambridge’s older homes with exterior chimneys that heat up in summer sun.
- Black, oily deposits on the damper or firebox walls. These indicate Class III glazed creosote, which ignites at lower temperatures and burns intensely. We’ve removed glazed buildup from chimneys in North Cambridge and Cambridge Highlands where homeowners burned seasoned hardwood and still developed dangerous accumulation due to appliance mismatch.
- Visible cracks in the firebox brick or mortar. Heat escaping through cracked firebrick can ignite adjacent framing. The camera inspection during our sweep examines whether the damage is superficial or whether heat has compromised the surrounding structure. In Cambridge’s wood-frame construction, this transition from masonry to combustible happens fast.
- It’s been more than 12 months since your last professional inspection. Even with minimal use, nests, moisture damage, and liner deterioration occur regardless of burn frequency. Cambridge’s squirrel and raccoon populations are active year-round, and a blocked flue doesn’t announce itself until you light the first fire of the season.
Our Chimney Cleaning & Sweep Process - Step by Step
- 1
Schedule and confirm. Call (857) 309-1908 and you’ll reach a live person, not a voicemail tree. We confirm your address, appliance type, and any symptoms you’ve noticed. You receive a text with your technician’s name, photo, and license number before arrival. This is Haven Standard Clause 3: verified crews, background-checked and uniformed.
- 2
Arrival and protection. Your technician arrives within the scheduled window, lays protective coverings from the door to the work area, and inspects the exterior chimney for obvious damage, proper cap installation, and crown condition. In Cambridge, we note whether the chimney is interior or exterior, single-flue or multi-flue, and whether ice dam history suggests moisture intrusion.
- 3
Camera inspection before cleaning. We lower the camera before touching a brush. This baseline documentation, required under Clause 4 of the Haven Standard, shows you exactly what condition your flue is in. We identify creosote class, liner integrity, mortar joint condition, and any obstructions. You watch the footage with us.
- 4
Written price, written scope, written warranty. Before any cleaning begins, we deliver a single-page document with the exact work to be performed, the exact price, and the terms of our 365-Day Done Right Promise. Haven Standard Clause 1, H.A.V.E.N. “Have it in writing.” No surprises, no upsells after the tech is in your home.

Cleaning, final documentation, and walkthrough. We perform the agreed scope using brushes, vacuums, and chemical treatments as specified. Afterward, we run the camera again to confirm clean surfaces and document the completed work. You receive the photo record, the written warranty, and our recommendation for next service. We text you a summary link within 24 hours.

What moves a Cambridge job toward the higher end: triple-decker shared flues requiring roof access, historic homes with unlined brick chimneys needing gentle handling, and properties where previous DIY cleaning left brush heads lodged in the flue. We’ve extracted competitor brush fragments from chimneys in Inman Square and near Central Square.
How to avoid overpaying: demand a written price before work starts, verify that camera inspection is included rather than billed separately, and ask whether the quote covers just the flue or the full system including smoke chamber and firebox. Some Cambridge competitors quote a low sweep price, then add $150-$250 for “inspection” and “documentation” we include as standard.
Our free estimate includes a phone consultation, a review of any prior inspection reports you have, and a clear explanation of what we’ll do and what it will cost. Call (857) 309-1908 for an exact quote.
