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.

Why Flint Chimney Sweep Is Marlborough’s Preferred Chimney Inspection Company
Homeowners in Marlborough call us because we run on a discipline most chimney companies won’t commit to in writing. Every inspection carries a written price before we start, and every repair we recommend comes with a 365-Day Done Right Promise: if it’s not done right, we make it right, valid for one full year from the service date. That is the Garrison Standard, the same code every Garrison Partners location follows since 2002.
Our techs arrive in uniform, background-checked, and inside the window we gave you. They are the reason Marlborough residents from the French Hill neighborhood to the Assabet River side of town keep our number on their fridge. Hank Delano, who leads our team, has built the operation around one idea: put everything in writing, and let the work speak for itself. You will not get a voicemail tree when you call. A living person answers around the clock, including weekends.
Level 2 Chimney Inspection in Marlborough
A Level 2 Chimney Inspection in Marlborough is the baseline we recommend for most homes here, especially older ones. It includes everything in a Level 1 visual check plus a camera scan of the flue interior, the smoke chamber, and the crown. In Marlborough’s 19th-century mill-worker triple-deckers and 1950s Capes near downtown, masonry chimneys were typically parged with mortar that spalls and opens up during Central Massachusetts freeze-thaw cycles. A Level 1 look from the firebox simply cannot see what is happening six feet up the liner.
A Level 2 inspection typically runs $350 – $550 in Marlborough. You get a written report with photos from the camera, so you can see exactly what we saw. No mystery, no “trust us on this one.”
When Marlborough Homes Need It
You need a Level 2 if you are buying or selling a home, if the chimney has been dormant for a full season, if you have burned a lot of unseasoned wood, or if you smell smoke on damp days. After weather events or a chimney fire, it is non-negotiable. We also recommend one before your first burn each season if the chimney is over 30 years old.
What the Camera Shows
The camera catches cracked flue tiles, third-degree creosote hiding behind the smoke chamber, and spalling crowns that let water track down into the firebox. In Marlborough, a homeowner on Lincoln Street called us because their damper would not close all the way. We ran a Level 2 and found first-degree creosote on the flue liner plus a deteriorating crown letting water into the smoke chamber. We swept the flue, documented everything with photos, and gave them a written scope for the crown repair. We told them what could safely wait until spring. No pressure.
Chimney Leak in Marlborough
A Chimney Leak in Marlborough is rarely just a leak. Freeze-thaw cycles on older masonry chimneys cause spalling crowns and failed flashing that let water in, and that water often travels down through a compromised flue liner before it ever shows up as a stain on the ceiling. The misdiagnosis is common: someone patches the flashing, the stain comes back, and the real problem was a cracked flue tile the whole time.
Leak diagnosis in Marlborough runs $350 – $550 for a Level 2 inspection, which tells us exactly where the water is entering. We work with Chimney Inspection protocols that start with the camera, not a guess. If the crown is shot, we write the repair scope with a price. If the liner is intact and the flashing is the culprit, we say that plainly and do not sell you liner work you do not need.
Signs It Is More Than Flashing
Damp smells in the firebox after rain, efflorescence (white mineral staining) on the exterior brick, or a damper that will not seat properly are clues the water is migrating through the masonry itself. In Marlborough’s older mill-era neighborhoods, spalling crowns on triple-deckers are common enough that we check the crown before we even look at the flashing.
When a Leak Can Wait
If the crown shows minor spalling and the flue liner is intact, the repair can usually wait a season. We will tell you that. We will write the price anyway, so you know what it costs when you are ready. What should not wait is a cracked flue liner, because that is where chimney fires and carbon monoxide problems start.
Trusted Brands We Service in Marlborough
We stock and service professional-grade components from brands like DuraFlex, HeatShield, and Copperfield, so Marlborough customers are not waiting on a part to ship from a supplier two states away. DuraFlex liners fit the narrow flues common in older Marlborough homes. HeatShield gives us a ceramic resurfacing option for chimneys that do not need a full reline. Copperfield flashing holds up to Central Massachusetts winters better than the thin flashing put in decades ago. When we write a scope, we name the brand and the reason we picked it for your chimney, not the margin.
Common Chimney Inspection Problems We See in Marlborough Homes
- Spalling crowns on pre-1960 masonry chimneys. Marlborough’s freeze-thaw cycles wear down old mortar crowns, and water gets in. The crown is one of the first things we camera-check because it drives so many “leak” calls that turn out to be crown failures.
- Cracked flue tiles hidden behind the smoke chamber. In triple-deckers and Capes built before the 1970s, unlined or clay-tiled flues crack over decades of heating cycles. A Level 1 visual check will not find this, and it is the exact condition that leads to chimney fires.
- Third-degree creosote from burning unseasoned wood. Marlborough homeowners without a covered woodpile often burn wood that never fully dried, which produces a hard, glaze-like creosote that a standard brush cannot always remove. We document it on camera and recommend a sweep plus follow-up inspection.
- Dampers that will not seal on Route 20-era builds. Homes built in the 1980s and 1990s along the Route 20 corridor often have original dampers that have warped or rusted. A damper that does not close pulls conditioned air out of the house all winter, and it is a sign the firebox needs a closer look.
Pricing for Chimney Inspection in Marlborough, MA

This is a visual check of the firebox, damper, and accessible flue interior, and it is enough if you burn clean, dry wood and had a sweep within the past year. A Level 2 inspection, with the camera, runs $350 – $550, and it is what we recommend before purchase, after a long dormancy, or if anything feels off with the draft.

FAQs About Chimney Inspection in Marlborough
Once a year if you burn regularly, and at minimum before your first fire each season. A chimney that burns one or two cords of dry hardwood a year needs a Level 1 check annually, and a Level 2 every two to three years. Marlborough’s older masonry chimneys with original clay liners are more likely to hide damage, so if your home is pre-1970, lean toward the Level 2. Call (830) 251-4560 and we will tell you honestly which one fits your chimney, not the schedule we want to sell.
A Level 1 is a visual check of the firebox, damper, and accessible flue interior. A Level 2 adds a camera scan of the full flue, smoke chamber, and crown, and it is the only way to see cracked tiles or hidden creosote. In Marlborough, where freeze-thaw damage is common, the camera is the difference between catching a spalled crown early and repairing a water-damaged wall two seasons later. The Level 2 is what we recommend as the baseline for older homes here, not an upsell.
No. The inspection price is fixed before we arrive, and finding creosote does not change it. If the camera shows buildup that needs a sweep, we give you a written price for the sweep separately. You approve or decline, and either way the inspection report is yours. No surprise fees, no pressure to add work.
Usually it is the crown or the flashing, and a Level 2 camera inspection tells us which one before we touch anything. Water stains on the ceiling near the chimney, damp smells in the firebox after rain, or efflorescence on the exterior brick all point to a chimney leak. We have seen enough Marlborough triple-deckers with spalled crowns that we check the crown first, then the flashing, then the liner. Call (830) 251-4560 and we will schedule a leak diagnosis with a written price before we book.
We do not promise same-day service, and we will not put a crew in your home before we have explained the scope and price. What we can do is answer the phone around the clock, book you into the next available slot, and tell you over the phone what to check first, including whether you should stop using the chimney until we arrive. If you smell smoke when there is no fire, call us at (830) 251-4560 and a live person will walk you through it while we get you on the schedule.
