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.
Fast, Reliable Chimney Cleaning & Sweep Across Hudson
A chimney sweep in Hudson typically costs between $189 and $349, and most homes take about an hour to clean. Top Hat Chimney has been sweeping the flues in this town since before the shoe factories fully went quiet, and Wendell Pike still answers his own phone. Call (781) 390-9211 for a straight quote before any tool comes off the truck.
Hudson’s housing stock is not like the newer subdivisions in the surrounding towns. Walk down Wood Square, or the side streets off Main near the Assabet River, and you’re looking at homes built between 1880 and 1930. Those chimneys have seen more Worcester County winters than most of us have seen birthdays. We know these stacks because we have been inside them, camera in hand, more times than we can count. That matters when you’re deciding who to trust with something that vents fire out of your house.
Why Top Hat Chimney Is Hudson’s Preferred Chimney Cleaning & Sweep Company
Wendell Pike founded Top Hat Chimney in 1999, and he has kept the operation owner-run ever since. Not a franchise. Not a call center. When you book a sweep in Hudson, the person who shows up is background-checked, in uniform, and knows the difference between the chimneys on Houghton Street and the chimneys in the post-war capes off Marlborough Street. That is not trivia. It changes how fast we spot a problem.
Our Chimney Cleaning & Sweep team gets to Hudson promptly, and we give you a real arrival window, not a four-hour maybe. If the window slips, you get a call. Every job ends the same way: camera footage reviewed with you on the spot, a plain-English verdict, and a price agreed upon in writing before we do anything beyond the sweep. The 90-Day Done Right Promise backs every completed job. One call brings Wendell back if it is not right.
Our Chimney Cleaning & Sweep Services in Hudson
Level 1 Inspection
A Level 1 inspection covers the readily accessible parts of the chimney and flue. For a Hudson homeowner who burns regularly and has not changed anything about their setup, this is the annual standard. We check the firebox, the damper, the flue interior where visible, and the exterior stack from the ground. Most annual sweeps in Hudson include a Level 1 inspection as standard practice.

Level 2 Inspection
If you’re buying or selling a house in Hudson, changing fuel sources, or you’ve had a chimney fire, Massachusetts fuel-gas code points you toward a Level 2. This is where we run a camera through the entire flue, top to bottom. For the older homes around the downtown rotary, a Level 2 is often the difference between catching a cracked clay tile and discovering it months later through a carbon monoxide detector at 2 a.m. This is the inspection we push hardest on for gas conversions. The camera does not guess.

Creosote Removal
Creosote removal in Hudson is not a one-size job. First-degree creosote is flaky soot; a brush handles it. Third-degree is a hard glaze that bonds to the flue wall like tar. We see third-degree routinely in older Hudson chimneys where the flue runs cold, especially unused fireplace flues in multi-flue stacks. That glaze requires rotary treatment, not a standard sweep. Leaving it means a chimney fire waiting for the right night. We show you the buildup on the camera before and after.

Soot Removal
For oil-fired furnaces and boilers, soot removal is a different animal than wood creosote. Soot is a fine, acidic dust that eats at old mortar when it mixes with condensation. In Hudson homes that still run oil, annual soot removal from the furnace flue is the cheapest insurance you can buy against a liner replacement. The newer gas conversions have their own problem, which we cover below.

For Hudson customers with aging masonry stacks, Gelco’s water-repellent treatments and Olympia’s liner systems are the ones we reach for most.

Common Chimney Cleaning & Sweep Problems We See in Hudson Homes
- Original unlined flues in pre-1930 worker housing. The shoe-factory era homes near downtown Hudson often have brick chimneys with no clay tile liner at all. The mortar inside those stacks has spent a century soaking up freeze-thaw cycles. A camera inspection is the only way to know if that flue is still safe to use.
- Condensation damage after an oil-to-gas conversion. Gas exhaust is cooler and wetter than oil exhaust. A flue sized for an oil burner suddenly gets puddles of acidic condensate pooling inside it. That eats mortar and tile from the inside out, and you will not see it from the ground.
- Spalled mortar joints hidden behind intact face brick. The exterior of the stack can look fine while the joints inside the flue are crumbling. Hudson’s hard freezes from November through March, punctuated by thaws, force water into micro-cracks and split them wider every year.
- Multi-flue stacks treated as single flues. Many older Hudson homes have two or three flues sharing one exterior chase. Cleaning the fireplace flue while ignoring the furnace flue is how a cracked tile gets missed and carbon monoxide finds its way into living space.
Pricing for Chimney Cleaning & Sweep in Hudson, MA
A standard chimney sweep in Hudson runs $189 to $249 for a single flue with a basic inspection. Two-flue stacks, common in the older multi-family homes near downtown, run $289 to $349. A full Level 2 camera inspection adds $150 to $250 depending on the number of flues and access difficulty. Creosote removal with rotary treatment for glazed third-degree buildup starts around $250 and goes up with severity. Soot removal for oil furnace flues lands in the $180 to $220 range.

FAQs - Chimney Cleaning & Sweep in Hudson
An inspection is the only way to confirm the flue has not cracked, spalled, or separated since last season. Hudson’s hard freeze-thaw cycles work on mortar every winter whether you burn or not. A chimney that sits unused still takes water, swells, and contracts. Once a year, burn or no burn. Your flue does not care how the fire looks. It cares how it breathes. Call (781) 390-9211 for an inspection that includes camera proof.
Maybe not, and the reason is condensation. Gas produces cooler, wetter exhaust than oil, and an old flue sized for oil gets wet, acidic condensate pooling inside it. The flue may look clean while the acid eats the mortar from the inside. A Level 2 inspection with a camera is the only way to know. On a two-family home near the downtown rotary, we swept three flues sharing one exterior chase after the homeowner converted from oil to gas. The camera found condensation staining inside the furnace flue and glaze-like creosote in the unused fireplace flue. We documented it all on screen, recommended a HeatShield resurfacing instead of a rebuild, and the owner approved it the same day. Nothing gets recommended without you seeing the footage first. Call (781) 390-9211 for a Level 2 inspection.
You can, but each flue must be individually traced, documented, and confirmed as properly separated before any new appliance connection is legal under Massachusetts fuel-gas code. A multi-flue shared chase means a cracked tile in one flue can affect the others. We run a camera through each flue separately and show you the condition of each one. That is the only responsible way to answer your question. Call (781) 390-9211 for a thorough Level 2 inspection before you buy the insert.
Most Hudson wood-burning chimneys have second-degree creosote by spring: a flaky, tar-like buildup that wants a thorough brushing. In older unlined or clay-tile flues, especially unused fireplace flues in multi-flue stacks, we find third-degree glaze. That hard, shiny deposit cannot be brushed out; it requires rotary treatment. First-degree is a brush job. Third-degree is a glaze. Catch it early. Call (781) 390-9211 to schedule a sweep and find out which one you have.
Look for spalled brick faces on the exterior stack, white efflorescence staining, damp smells near the fireplace after rain, or water in the firebox. Hudson gets over 50 inches of snow most years, and the crowns and flashing on older stacks take repeated ice and snow load. A cracked crown lets water into the stack, and the refreeze cycle spreads shallow cracks into deep ones. We inspect crowns and flashing as part of every sweep. The camera footage and a plain-English verdict, every time, no exceptions. Call (781) 390-9211 before next winter’s freeze cycle.
If you live in Hudson and you want someone who will show you proof before recommending work, call (781) 390-9211. Wendell and his crew will be straight with you. Estimates are free, and the price you hear on the phone is the price you pay. The 90-Day Done Right Promise goes on every job in writing.
