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.

AfterFast, Reliable Chimney Inspection Across Cambridge
Flint Chimney Sweep provides thorough chimney inspections throughout Cambridge, MA, structured around one thing: documentation. Every inspection includes a camera run through each flue and a photo report you keep. You see what we see. No verbal “looks fine” with nothing behind it. If you own a home in Cambridgeport, Mid-Cambridge, or North Cambridge, call (830) 251-4560 to book.
We’ve worked on enough pre-war triple-deckers and converted two-families between Harvard Square and Porter Square to know that Cambridge chimneys rarely fail all at once. They fail flue by flue. Our job is to show you which flue needs attention, which one can wait, and what it costs before any work begins.
Why Flint Chimney Sweep Is Cambridge’s Preferred Chimney Inspection Company
Cambridge homeowners call us because we put the inspection price on paper before the appointment. The number we quote is the number you pay. That’s the Garrison Standard: written price first, written guarantee on any repair that follows, and a return visit at no charge if a covered repair fails within 365 days.
Our technicians are background-checked and uniformed. You’ll know the name of the person coming to your door. Dispatch and scheduling are coordinated from the brand’s Boston office, and our crews serve Cambridge directly. When you call, a live person answers. Not a voicemail tree, not a callback form. Day or night.
Hank Delano leads our inspection work across the Cambridge area. The standard he set is simple: if we recommend a repair, the photo report has to show why. If the footage doesn’t justify it, we don’t recommend it. That’s why our Chimney Inspection reports read like evidence, not sales pitches.
Chimney Flue Inspection in Cambridge
Chimney Flue Inspection is the core of what we do in Cambridge, because most older homes here don’t have one flue. They have two, three, or four running side by side inside a single masonry stack. A flue inspection means running a camera down each individual flue, not just the one connected to the appliance you think is misbehaving. That distinction matters more in Cambridge than almost anywhere else in the metro.
A standard flue inspection with camera documentation typically runs $185 to $295 in Cambridge, depending on how many flues are in the stack and whether roof access requires a ladder or scaffolding. The price is set before we arrive, not after.
What the camera sees
We look for glazed creosote, cracked clay tiles, spalling brick, missing mortar joints, and improper flue separation at the smoke chamber. The camera records everything. You receive a photo report with stills and notes keyed to each flue.
When it matters most
If you’ve just bought a Cambridge home, schedule a flue inspection before your first burning season. The previous owner’s maintenance habits are not something you want to discover in January. Real estate transactions in this market move fast, and most standard home inspections do not scope chimney interiors.
Chimney Fire in Cambridge
Chimney Fire risk in Cambridge concentrates in the city’s older wood-stove flues, especially in triple-deckers and two-family conversions where a shared masonry stack serves multiple units. The fire itself usually starts when third-degree glazed creosote ignites. That glaze forms when wood burns at low temperature for years, often in a stove the landlord never knew was used daily.
A Level 1 visual inspection in Cambridge costs $125 to $175. A Level 2 inspection, which includes full camera runs through every flue, runs $225 to $350 for a typical multi-flue stack. Level 3 inspections, which become necessary after a chimney fire or structural movement, start at $450 because they involve accessing concealed sections of the chimney.
What we check after a suspected fire
Signs of past chimney fire include honeycomb-textured creosote, cracked flue tiles, warped metal components, and visible mortar displacement. If a Cambridge homeowner reports a loud rumble from the chimney or smoke pushing into adjacent rooms, we document everything with the camera before recommending any repair. The report is yours regardless of whether you hire us for the fix.
When it can wait
Second-degree creosote in a flue you use once a month can sometimes wait until spring. Third-degree glazed creosote in a flue connected to a working wood stove cannot. We’ll tell you which side of that line your flue sits on, and why.
Trusted Brands We Service in Cambridge
When a Cambridge inspection turns up a liner problem, we specify materials by job, not by margin. That means HeatShield resurfacing for minor spalling and cracked mortar joints, or an Olympia Chimney stainless steel liner when the existing clay liner has failed beyond repair. We keep common components stocked for Cambridge work, which means less waiting on parts after the inspection is done. Hank Delano insists on this: the brand goes in the written quote, so you can verify the product before approving the work.
Common Chimney Inspection Problems We See in Cambridge Homes
- Multiple flues treated as one chimney. A sweep services only the flue the customer complains about and never documents the adjacent wood-stove flue coated in glazed creosote. In a Cambridge triple-decker, that neighboring flue can be inches away inside the same stack.
- Missing or improperly sealed chimney caps. Rain and chimney swifts enter through open caps, causing spalled brick and blocked draft. Homeowners get told the wood is wet, when the real problem is water getting in at the top.
- No photo record of the flue liner. A 100-year-old clay liner with hairline cracks gets a verbal “looks okay.” A year later, the cracks have widened and the owner has no baseline image to compare against.
- Cross-draw between flues at the smoke chamber. Smoke from one unit rolls across into a neighboring flue because the chambers were never properly separated. This is common in pre-1930 Cambridge construction and invisible without a camera run.
Pricing for Chimney Inspection in Cambridge, MA
A Level 1 inspection in Cambridge typically costs $125 to $175. A Level 2 inspection, which every buyer, seller, and multi-flue homeowner should get, runs $225 to $350 depending on flue count and roof access. Level 3 inspections start around $450 and apply after chimney fires or structural concerns. These are flat prices agreed to before we book the appointment. The written quote includes the full scope: number of flues, camera runs, and what the photo report covers. Call (830) 251-4560 and we’ll give you a number on the first call, not an estimate range after a “free evaluation” that turns into a sales visit.

FAQs About Chimney Inspection in Cambridge
One inspection appointment covers the whole stack, but each flue inside it gets scoped separately. We treat a three-flue Cambridge chimney as three inspections in one visit. The report is organized flue by flue, so you know exactly which tenant’s stove or furnace produced what footage. If you’re an owner-occupant in a converted two-family, you get one price for the full stack, not a per-flue surcharge.
Once a year if you burn at all, and before the first season after buying the home. Occasional burning in Cambridge still produces second-degree creosote, and in an old unlined or partially lined flue, that’s enough to matter. If you burn nothing and the chimney only vents a gas furnace, every two to three years is reasonable unless you notice staining, odor, or spalling. Call (830) 251-4560 and we’ll tell you straight if an annual visit is overkill for your setup.
Yes. We give a written price when you book, not after we walk in the door. That number covers the full inspection: ladder setup, camera runs through each flue, and the photo report. The only thing that changes a quote is flue count and roof access difficulty, and we confirm those details on the first call based on what you tell us about the property.
Stills and timestamped notes for each flue, keyed to what the camera captured: creosote grade, cracked tiles, spalling, mortar joints, cap condition, and flue separation at the smoke chamber. You see the report during the visit and keep a copy after. If a repair is recommended, the relevant footage is highlighted in the report. That report is the basis for our written repair guarantee, and it’s yours regardless of who does the work.
Third-degree glazed creosote is the material that fuels chimney fires, and in a flue connected to a working wood stove, it should not wait. In a dormant flue with no appliance attached, the risk is lower and the work can sometimes be scheduled over the next few months. We’ll give you a straight answer based on what the footage shows, not on urgency. Call (830) 251-4560 for a written quote either way.
