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 Hudson’s Preferred Chimney Repair Company
Hudson homeowners have a specific problem with chimney companies: they show up late, find expensive problems you can’t verify, and leave you with a number that wasn’t in the quote. We run on a different standard. Every Flint Chimney Sweep job gets a written price before a single tool comes off the truck, under what we call the Garrison Standard. The number you approve is the number on the invoice. And every repair carries a written guarantee valid for one full year. If a covered repair fails inside that window, we return at no charge, no argument.
Our technicians are background-checked and uniformed, so you know who’s walking through your door. Phones are staffed by a live person around the clock, not a callback form. Hank Delano leads the crew here, and the work reflects that: disciplined, documented, and direct. That’s why Hudson homeowners keep our number close when the first frost hits and the chimney starts acting up.
Chimney Cap Replacement in Hudson
Chimney cap replacement is one of the most common repairs we do in Hudson, and it usually runs $280 to $490 here, parts included. A chimney cap is the metal shield at the top of the flue that keeps rain, snow, leaves, squirrels, and birds out while allowing smoke to escape. When the cap rusts through or goes missing, water pours straight down the flue, accelerating rust on the damper plate and seeping into the brickwork below. In Hudson’s Assabet River valley, where damp air and heavy tree canopy keep chimneys wet longer than the surrounding hill towns, a failed cap does damage fast.
What We See on Valley Chimneys
On a call off Houghton Street near the Assabet, our tech opened the firebox on a 1950s ranch and found the damper plate frozen shut with rust and the crown cracked with spalling brick at the top course. Wet masonry, not creosote, was the real problem. We fitted a new stainless chimney cap, rebuilt the crown, and installed a HeatShield flue liner repair, then handed the homeowner a photo report of every stage.
Why a Stainless Cap Makes Sense Here
We specify stainless steel caps for Hudson chimneys because they outlast galvanized by years in our wet, acidic valley air. A quality cap from Copperfield or Famco, sized right for your flue, will protect the liner and damper from what March and April rainstorms bring. The job takes about an hour once we’re on the roof, and we’ll show you photos of the old cap and the new one before we leave.
Chimney Liner Installation in Hudson
Chimney liner installation in Hudson typically runs $1,800 to $2,400 for a full stainless steel liner, while a HeatShield resurfacing job can come in lower depending on the flue condition. The liner is the inner channel that carries smoke and fumes safely out of your house. When it cracks, gaps open, or tiles separate, carbon monoxide and heat can escape into the wall cavity or living space. That’s a genuine safety issue, and it’s the primary reason we recommend a Level 2 camera inspection whenever a liner repair is on the table.
What the Camera Shows Us
We run a camera down the flue on every liner job. The footage shows exactly where the liner has failed, whether it’s a cracked clay tile at the firebox throat or a seam separation mid-flue. You see the same images we see. Nothing gets recommended without visual evidence in your hands. If the liner can safely wait a season, we’ll tell you that plainly.
DuraFlex and HeatShield Options
For full relining we standardize on DuraFlex stainless steel, a flexible liner that’s UL-listed for wood, gas, and oil appliances. For smaller spalls and cracked joints, HeatShield resurfacing can often restore the flue without the cost of a full replacement. Both carry our one-year written guarantee, and we’ll walk you through which one fits your fireplace, furnace, or boiler before you spend a dollar.
Trusted Brands We Service in Hudson
We work with chimney components from Copperfield, Famco, DuraFlex, and HeatShield, and we keep common caps, dampers, and flashing parts stocked for quick turnaround on Hudson jobs. When a repair calls for a specific part, we don’t make you wait weeks while a generic substitute gets ordered. We source from trade suppliers who carry these brands specifically, so the cap we install on a Colonial on Brigham Street is the same cap we’d install on a ranch off Washington Street: specified by job, not by margin. If you want to verify the materials we cite, every brand name is independent and well established in the fireplace and chimney trade.
Common Chimney Repair Problems We See in Hudson Homes
- Crumbling mortar joints and spalled brick at the crown. The Assabet River valley keeps chimneys wet, and repeated freeze-thaw cycles pop the top courses of brick. This is the repair we see far more often in Hudson than creosote problems.
- Rusted damper plates. Rain and damp air get past a failed cap or cracked crown and settle on the cast-iron damper. Hudson homeowners often discover the damper won’t budge in October, when burning season starts.
- Flashing leaks where the roof meets the chimney. Hudson’s mix of 1950s ranches, 1920s colonials, and newer construction means flashing details vary widely. Leaks show up as brown ceiling stains that spread fast when the fall rains arrive.
- Failed flue liner tiles. Older Hudson chimneys often have original clay liners that crack from decades of heating cycles. This is where carbon monoxide risk lives, and it’s invisible without a camera inspection.

FAQs About Chimney Repair in Hudson
Most Hudson chimneys need cleaning every one to two years, but if you burn wet or unseasoned wood, or your stove runs hot and slow, once a season is smarter. The valley’s damp air can make creosote cling differently than it does in dryer hill towns. The honest answer: get a Level 2 camera inspection. It shows what’s really inside. Call (830) 251-4560 and we’ll give you a straight recommendation.
That’s spalling, and in Hudson it’s usually water, not age. The Assabet valley’s damp air and heavy tree canopy keep the crown and top courses wetter longer, and freeze-thaw cycles pop the brick faces off over time. Mortar repointing and a rebuilt crown usually fix it. If you catch it early, the cost is in the $700 to $1,500 range. Ignore it, and the rebuild bill starts at $2,000.
A Level 2 camera inspection shows the full flue length, including the smoke chamber where the damper sits and the joints you can’t see from the firebox. In Hudson, it most often turns up cracked clay liners, open mortar joints in the smoke chamber, and rusted dampers hiding behind a clean-looking firebox. The camera report is photo proof, not opinion. We don’t recommend work without it.
Yes. If we’re sweeping and the inspection turns up a failed cap, cracked crown, or flashing leak, we can often handle it the same day, assuming the parts are on the truck. We stock common stainless caps and Copperfield dampers for Hudson jobs specifically so we don’t have to schedule a second visit. You’ll still get the written price before the extra work starts.
If the camera inspection shows minor mortar erosion near the top of the flue, and there’s no water penetration into the living space, you can usually wait until spring. If the liner is cracked, the cap is gone, or the damper is rusted shut, do not wait. Those are safety issues, not cosmetic ones. When in doubt, call (830) 251-4560 and we’ll tell you the truth, even when the truth is that you can wait.
