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 Hudson
A chimney inspection in Hudson, MA typically runs $189 – $489 depending on the level and whether a camera scope is needed. Most inspections take 60 – 90 minutes on site, and you’ll have a written report with photos before we leave the driveway. We know Hudson’s older homes well, because we’re in them every week during the fall rush. If you need a chimney checked before burning season, call (336) 863-3889 and a live person will answer.
This town isn’t like Marlborough or Stow when it comes to chimneys. Hudson’s core is packed with worker housing from the 1880s through the 1920s, and those chimneys were built for coal and wood heat. Many of them still work, but they weren’t designed for what we ask of them now. That’s why our Chimney Inspection team approaches Hudson jobs as stack surveys, not just flue checks. When you call, we’ll tell you exactly who’s coming, their name and photo, before the truck rolls.
Why Alcott Chimney Sweep Is Hudson’s Preferred Chimney Inspection Company
Alcott Chimney Sweep has served homeowners since 2002, and Ruben Castellano built this company around a simple idea: you should never wonder who’s walking up your front steps. Every technician we send into Hudson is background-checked and identity-verified under the Threshold Standard, which is not an optional add-on. It’s how we hire. You’ll get the technician’s name and photo before the appointment, and that person will show a photo ID badge at the door. Every time. No exceptions.
Hudson homeowners call us because we give straight answers about chimneys that are often older than anyone living in the house. When we inspect a flue on Houghton Street or a two-family near the old mill district, we’re looking at masonry that’s been through more than a century of Assabet Valley winters. Freeze-thaw cycling here is harsher than the I-495 corridor because Hudson sits inland enough to hold the cold longer. That means mortar joints fail faster, crowns crack sooner, and more brick spalls. We write our reports with that context, not from a generic template.
Every inspection comes with a written price before we start any work. Not an estimate range you have to negotiate. A real number. And if we find a repair and you approve it, that repair carries a written guarantee. If it fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it’s in writing on every job.
Level 2 Chimney Inspection in Hudson
A Level 2 Chimney Inspection in Hudson is the inspection you need when something about the chimney has changed: you bought the house, the property changed hands, a storm hit, or the flue hasn’t been used in years. This inspection includes everything in a Level 1, plus a camera scan of the full flue interior, an attic and crawlspace check, and a close look at the accessible portions of the chimney’s exterior and interior structure. In Hudson, where so many chimneys are pre-liner and over a century old, this inspection is the one that finds what a visual check can’t.
Camera Scope of the Full Stack
We run a camera from the flue opening down to the smoke chamber and up through the crown. The camera catches cracked tiles, separations between flue sections, and animal nesting that you’d never see from the roof or the firebox. On Hudson’s shared stacks, this is where we document which appliance vents where and whether one flue’s failure is pushing exhaust into a neighbor’s unit.
After a Chimney Fire, Hail, or Building Transfer
If you’re buying a worker cottage near the old mill district or taking over a triple-decker, a Level 2 is required by most real estate contracts and mortgage lenders. It’s also smart after any weather event that could’ve hit the crown or flashing. We’ll write the report in plain English and give you the photos so you can see exactly what we saw.
Chimney Leak in Hudson
A Chimney Leak in Hudson usually shows up as water in the firebox, staining on the ceiling near the flue, or a musty smell after rain. The cause isn’t always what you’d guess. Around here, we find that freeze-thaw cycling has opened the crown, or the flashing has pulled away from the brick, or the brick itself is soaking water like a sponge because it was never sealed. We find the entry point, not just the symptom, and we show you the photos before we quote any fix.
Crown, Flashing, and Mortar Loss
Hudson’s older chimneys often have crowns that were poured without proper expansion gaps. When water gets in and freezes, the crown cracks open further. We inspect the crown, the flashing around the roofline, and the mortar joints from the roof line down. If it’s a repair we can do without a rebuild, we’ll say so and price it flat before starting.
Moisture in the Firebox From a Shared Stack
In attached housing and two-families, we sometimes find that the leak isn’t from your side at all. A neighbor’s side of the stack is failing or an unused flue has become an open drain. We’ll trace the water path with the camera and tell you honestly whether the repair is on your side, their side, or both. No guesswork.
Trusted Brands We Service in Hudson
We install and service what chimney professionals actually specify, not whatever is cheapest at the hardware store. On Hudson jobs we regularly work with HeatShield resurfacing for smoke chambers and flue interiors, Gelco for crown repair and waterproofing, and Olympia Chimney caps and dampers. These materials hold up to Assabet Valley winters. We keep common components stocked for Hudson-area service calls, which means less waiting when a crown needs sealing or a cap needs replacing before the weather turns.
Common Chimney Inspection Problems We See in Hudson Homes
- Shared stacks with multiple appliances: Many worker-era two-families and triple-deckers vent two or three appliances into one masonry stack. One flue’s blockage can push exhaust into another unit’s living space. A Level 2 with a camera is the only way to confirm each flue is separate and intact.
- Dormant chimneys brought back into use: A Chase Street or Manning Street home changes hands, the new owner opens a chimney that’s been capped for a decade, and we find raccoon nesting, a collapsed liner section, or a firebox soaked from years of roof leaks. First-time inspections on these flues almost always need more than a visual check.
- Freeze-thaw damage at the crown and upper courses: Hudson’s inland position means longer cold snaps than the coastal belt. Mortar joints open, brick faces pop, and crowns crack. Water gets in, freezes, and makes the problem worse every year it’s ignored.
- Creosote buildup in wood-burning flues: We’re far enough from the coast that Hudson wood-burning seasons run long. Heavy creosote in a stove pipe or smoke chamber is common by March. Annual inspects are not just recommended here; they’re the difference between a safe burn and a chimney fire risk.

FAQs About Chimney Inspection in Hudson
You need a Level 2 inspection. A capped chimney that’s been unused for years has likely been home to animals, absorbed roof water, or developed liner damage nobody saw because nobody was looking. A Level 1 visual check won’t see inside the flue or the smoke chamber where these problems hide. A Level 2 includes a camera scan and the attic and crawlspace documentation that’ll give you a real answer before you light the first fire. Call (336) 863-3889 and we’ll schedule it for you.
Yes, and this is one of the most important things we check in Hudson. If the two units share a masonry stack and one flue isn’t drafting or has a crack, exhaust from their appliance can enter your flue or living space. We pressure-test the shared smoke chamber and camera each flue to confirm they’re separately lined and functioning. This isn’t a theoretical risk; we’ve documented it on Houghton Street and throughout the mill district. Don’t wait until you smell exhaust inside. Call us and we’ll check the whole stack.
Hudson sits inland in the Assabet River valley and holds cold air longer than Stow’s higher, more open exposure. Every freeze-thaw cycle opens tiny cracks a little more. Once water gets into the crown’s pores and freezes, the cracks widen through the winter. Hudson’s older mortar and concrete crowns weren’t poured with expansion joints, so they fail faster. We assess the crown condition on every inspection and can resurface or recast it with materials like Gelco before the damage reaches the flue liner. We’ll give you a written price before touching anything.
Every year, before the burning season starts. Hudson’s inland climate produces longer, colder winters than coastal towns, which means longer fire seasons and heavier creosote deposits. If you burn daily from November through March, schedule your inspection in September or October. That gives us time to address any creosote, liner damage, or crown issues before you’re relying on the stove at 20 degrees. We’ll set up an annual reminder so it doesn’t get forgotten in the fall rush.
Usually, yes. Most of Hudson’s older masonry stacks have solid brick structure even when the original clay tiles are cracked or missing entirely. We can install a DuraFlex or HeatShield liner system inside the existing flue, or apply HeatShield resurfacing to stabilize and seal the old tiles without tearing anything down. We’ll only recommend what the camera proves is necessary. If the brick itself has failed, we’ll say so plainly and explain your options. You’ll see the photos and get a written price before any work begins.
