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 Boston
A standard chimney inspection in Boston runs $199 – $349 for a Level 1, and $349 – $649 for a Level 2 with camera. Most inspections take 60 – 90 minutes, and you get a written report with photos before we leave the driveway. In Boston’s brick rowhouses, an inspection is not a formality: shared party walls and century-old mortar hide problems a rooftop glance will miss. We schedule Boston inspections Monday through Saturday, with a live person answering the phone around the clock at (830) 251-4560.
Why Flint Chimney Sweep Is Boston’s Preferred Chimney Inspection Company
Boston homeowners call us because we put the inspection report in writing, with photos, before any repair discussion starts. Our Chimney Inspection team works on rowhouses, triple-deckers, and single-family colonials across the city, and we know what hides behind a clean firebox in a Charlestown party-wall chimney. The company was founded in 2002 as part of the Garrison Partners family, and every technician who walks through your door is background-checked and uniformed.
What separates us from the chimney companies that no-show or move the price at the door is simple: you get a written price before any tool comes off the truck. That applies to inspections and every repair we recommend after one. Boston homeowners see the number on the written scope and know the invoice will match it. Our 365-Day Done Right Promise on repairs means if a covered fix fails within one full year, we return at no charge. No argument, no second invoice.
Serving Boston means understanding freeze-thaw cycles that crack crowns by March, raccoons nesting in unused flues off Blue Hill Avenue, and oil-to-gas conversions in older Hyde Park homes that need a liner assessment before the new boiler fires. Hank Delano leads our Boston crews, and the standard he enforces is the same Garrison Standard every location follows.
Level 2 Chimney Inspection in Boston
A Level 2 Chimney Inspection in Boston is what you need before buying a rowhouse, after a chimney fire, after an earthquake (rare but not unheard of here), or when you convert a heating appliance to gas. It includes everything in a Level 1 sweep plus a camera scan of the entire flue interior, the smoke chamber, and accessible portions of the exterior. In Boston’s brick rowhouse stock, a Level 2 is the inspection that actually finds liner cracks and failed party-wall flashing, because it does not stop at what the chimney crown looks like from the street.
Camera Inspection
We run a camera the full length of the flue, through the smoke chamber, and up to the cap. The photo report you receive shows exactly what the camera saw, labeled in plain English. If there is a gap in the clay liner behind the damper, you will see it in the photo. If the report shows nothing urgent, you can confidently wait another year.
Flue Inspection
A flue inspection in a Boston rowhouse often means checking a shared masonry stack that vents two or three units. Interior flue cracks do not show from the rooftop, and that is why we camera-scan every flue we inspect rather than running a brush and calling it done. A disconnected stainless liner section back in the smoke chamber is a finding we have documented more than once in the South End and Dorchester.
Chimney Leak in Boston
A Chimney Leak in Boston typically shows up as a musty smell near the firebox after rain, staining on the wall beside the hearth, or water in the firebox itself. In Boston’s rowhouses, the leak may not even be on your side of the party wall: your neighbor’s failed flashing can send water into your shared chimney mass and through the brick. That is why we inspect the crown, the flashing, and the smoke chamber together when a leak is suspected, rather than re-caulking a cap and hoping it stops.
Crown Failure
The chimney crown is the concrete slab that caps the masonry and sheds water away from the flue. Boston freeze-thaw cycles crack crowns by early spring nearly every year, and a cracked crown admits water that runs down the flue and into the smoke chamber. On a rowhouse crown shared by adjacent units, both sides need assessment at the same time, because sealing only one half leaves the other side pumping water into the shared brick.
Party-Wall Flashing
Flashing is the metal seam where the chimney meets the roofline. On Boston rowhouses with a shared chimney stack, that seam often crosses a party wall, and the flashing on your neighbor’s side affects the masonry on yours. A camera inspection confirms whether the water is entering at the flashing or through the crown, because those are two different repairs with two different scopes.
Trusted Brands We Service in Boston
We specify professional-grade materials by the job, not by the margin on the material. For Boston homes we install and work with Copperfield caps and dampers, Famco chimney caps and fans, and DuraFlex stainless liners. That means when a Dorchester triple-decker needs a new liner, the invoice names the product and the length, and you can verify the brand before we order anything. We keep stock on hand for faster turnaround on common Boston repairs, so a written inspection finding does not turn into a three-week wait.
Common Chimney Inspection Problems We See in Boston Homes
- Hidden mortar loss behind the damper. The firebox looks fine from the living room, but the smoke chamber above it has spalling bricks and missing mortar. A camera inspection finds this in minutes; a visual sweep alone will not.
- Shared party-wall cracks. In Charlestown, the South End, and Beacon Hill, a single masonry stack vents multiple rowhouse units. A crack in the shared flue sends carbon monoxide into the neighbor’s living space, not just yours.
- Freeze-thaw crown failure. Boston’s winter temperature swings crack chimney crowns every spring. Water gets in, sits in the smoke chamber, and rots the mortar from the inside while the exterior still looks silver.
- Animal nesting in unused flues. Raccoons and squirrels use Boston chimneys as den sites in late winter, and a nest fills the flue with combustible material. An inspection the first season the fireplace sits unused is cheaper than a chimney fire later.
Pricing for Chimney Inspection in Boston, MA
A Level 1 inspection in Boston runs $199 – $349. A Level 2 with camera runs $349 – $649, and a Level 3, which involves removing masonry to access hidden sections, typically runs $900 – $2,000 depending on access. Boston rowhouse inspections sometimes add time for shared stack access or difficult roof geometry, and the written quote reflects that before we begin. What affects the number most is which level you need and whether the flue is shared with an adjacent unit. We give you a flat written price before the inspection starts, and the number on the written scope is the number on the invoice. Call (830) 251-4560 for a free estimate.

FAQs About Chimney Inspection in Boston
Yes, because Boston’s freeze-thaw cycles and animal activity degrade mortar, caps, and liners even when the firebox stays cold all winter. We install copper and stainless components where the weather does the most damage, and the annual inspection catches the crown crack before it lets water into the flue. If money is tight, a Level 1 every year with a Level 2 camera scan every third year is a reasonable cadence for a fireplace you use only occasionally. Call (830) 251-4560 to schedule one.
A Level 2 includes a full camera scan of the flue interior, the smoke chamber, and the chimney exterior, where a basic sweep only clears soot and does not assess concealed damage. In a Boston rowhouse, that camera scan is what finds disconnected liner sections and cracked mortar behind the damper. A sweep without a camera would not detect any of it. We email you the photo report before we leave.
That smell is almost always an inspection issue, not a cleaning issue. Musty odor after rain means water is entering the flue or the masonry mass, usually through a cracked crown or failed flashing. Sweeping alone cannot fix it. We run a Level 2 inspection, find the entry point with the camera, and give you a written scope for the crown or flashing repair before you spend a dollar on a sweep.
If the chimney has a stainless liner, inspection can be done every two years instead of every year, provided the liner is intact and single-family with no shared flue. Boston rowhouses with a shared masonry stack still need an annual exterior check because the common brick and crown degrade regardless of what liner sits inside your flue. The difference is the camera scan inside the liner can wait, not the crown and flashing check. We will tell you which cadence fits your setup, in writing, after the first inspection.
Third-degree creosote is a hard, glazed tar that forms when flue temperatures run low, common in Boston chimneys venting high-efficiency gas appliances or burning unseasoned cordwood. A regular brush passes over it without removing much, and attempting to scrape it can damage older clay liners in rowhouse flues. Removal requires chemical treatment or mechanical methods rated for glazed creosote, and that is a repair decision we document with camera photos before recommending. Call (830) 251-4560 for an inspection that tells you honestly whether the creosote is third-degree and what it actually takes to remove.
