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 Cap & Crown Across Hudson
Chimney cap and crown work in Hudson, MA typically runs $180-$480 for a standard single-flue cap installation or crown repair, and $350-$900 for a custom multi-flue cap on a shared stack. Most jobs in Hudson are completed same-day once the parts are on the truck. The real variable isn’t the labor; it’s what we find when we get up on the roof. If you live near Wood Square or over on the Manning Street side, you already know these older stacks don’t give up their problems easily. Call Wendell at (781) 390-9211 and he’ll tell you plainly what the chimney actually needs.

Our Chimney Cap & Crown Services in Hudson
We handle the full Chimney Cap & Crown scope in Hudson, but what actually gets used depends on the stack. An 1880s worker’s cottage near downtown Hudson needs different hardware than a 1970s ranch off of Cox Street. Wendell and his crew size the work to the house, not to a brochure.
Cap Installation
A proper stainless cap keeps rain, snow, and raccoons out of the flue. On Hudson’s older homes, we often find the original cap rusted through or missing entirely. The furnace and water heater have been venting into an open flue for years, catching every nor’easter that rolls through Worcester County.
Cap Replacement
Rusted single-flue caps are the most common replacement we do in Hudson. But here’s the thing: if the cap rusted out, the crown underneath it probably has cracks too. We don’t just swap hardware. We inspect the crown while we’re up there, and we’ll tell you if it can wait or if it needs work now.
Crown Repair
The chimney crown is the concrete or masonry slab that caps the top of the stack. In Hudson’s freeze-thaw climate, water gets into micro-cracks, freezes, expands, and spalls the mortar. A crown that looks fine from the ground can be quietly falling apart from the top down. We rebuild crowns and apply a Gelco crown coat to seal the repair against the next hard freeze.
Crown Coating
For crowns that are still structurally sound but showing surface cracking, a coating buys years at a fraction of a rebuild. We use Gelco crown coat specifically because it flexes with temperature swings instead of cracking like rigid cement. On Hudson’s older masonry, that flexibility matters.

Trusted Brands We Service in Hudson
We install and service Famco caps, Copperfield multi-flue caps, and Gelco crown coatings, plus liners from DuraFlex and HeatShield. Because Hudson’s housing stock skews older and shared-flue-heavy, we keep a good inventory of multi-flue hardware on hand rather than making you wait on a special order. If your stack has two or three flues, we’re likely pulling a Copperfield multi-flue cap off the truck, not ordering one in. Wendell stocks what Hudson actually needs.
Common Chimney Cap & Crown Problems We See in Hudson Homes
Wendell has been walking Hudson roofs long enough to know what he’ll find before he climbs the ladder. Here’s what shows up again and again:
- Cracked crowns on shared stacks. In the dense streets off Main Street and Manning Street, many two- and three-family homes share one exterior chimney stack with separate flues. A cracked crown funnels water into every flue at once, and Hudson’s repeated freeze-thaw cycles accelerate mortar loss until bricks visibly spall.
- Undersized caps that leave flues exposed. A single-flue cap sitting on a two- or three-flue stack leaves the adjacent flue open to animals and water. We find bird nests and dead squirrels in these unused flues all the time in Hudson’s older neighborhoods.
- Snow and ice loading on the crown. Hudson averages over 50 inches of snow a year. Snow piles on the crown, melts into the cap seam, refreezes overnight, and pries the cap loose or splits the masonry. Over time, the top flue tile spalls and the furnace backdrafts cold smoke into the basement.
- Oil-to-gas conversion damage. Hudson homeowners switching from oil to gas under Massachusetts efficiency incentives inherit a hidden problem. The original flue was sized for a hot oil exhaust. Gas burns cooler and wetter, and that moisture condenses inside the old flue, eroding mortar from the inside out. The crown and cap are part of that system: a compromised crown lets the moisture problem compound.
Pricing for Chimney Cap & Crown in Hudson, MA
Hudson pricing runs a bit higher than some neighboring towns because the work is more likely to involve shared stacks, steep roof pitches on late-1800s construction, and masonry in worse condition. A standard single-flue stainless cap installation runs $180-$340. Crown repair with a Gelco coat typically runs $240-$420. Custom multi-flue caps on shared Hudson stacks run $350-$900 depending on flue count and dimensions. If the crown needs a full rebuild, that’s $600-$1,200. We give free estimates before any tool comes off the truck, and the number you hear on the phone is the number on the invoice. $40 off any repair over $200, and seniors and veterans always get 10% off.

FAQs - Chimney Cap & Crown in Hudson
A multi-flue cap spans the entire top of the stack and protects every flue at once, including the unused one you never think about. Single-flue caps only cover the flues that still have appliances attached. In Hudson’s pre-1930 worker housing, we regularly see two- or three-flue stacks where one flue was abandoned decades ago. That abandoned flue is still open at the top, filling with rain, snow, and whatever else can climb in. A single-flue cap on the active flue does nothing for that. The water migrates into the shared masonry and compromises the entire stack. Worse, if a neighbor’s appliance vents into an adjacent flue, damage to the shared structure can create a cross-draft between flues. That’s a safety concern, not just a maintenance one. Call (781) 390-9211 and Wendell can tell you what your stack actually needs.
They destroy it slowly, then all at once. Water seeps into micro-cracks in the crown, freezes overnight when Hudson drops below 20 degrees, and expands by about 9 percent. Repeat that a few hundred times over a Worcester County winter and those micro-cracks become spalled mortar and loose brick. The crown can be failing for years before you see evidence from the ground. By the time the bricks are visibly spalling, the repair is more expensive. We use a Gelco crown coat specifically because it stays flexible through Hudson’s temperature swings. If you haven’t had the crown inspected in five years, it’s worth a look. Estimates are free.
Yes, it’s possible, and we’ve seen exactly that in Hudson’s attached and closely spaced older homes. When two or three flues share one stack, a damaged cap or compromised crown can let exhaust from an adjacent flue migrate into yours. Gas exhaust is pressurized and moist; it finds the path of least resistance. If the flue separation is intact, you shouldn’t smell a neighbor’s furnace. If the crown has degraded and the flue tiles are cracked, you might. This is one reason Massachusetts fuel-gas code requires each flue to be individually traced and documented before a wood insert or new appliance is connected to a shared stack. Don’t ignore that smell. Call Wendell at (781) 390-9211 and he’ll trace the flues and tell you what’s actually happening.
It makes the crown and cap work harder than they ever had to. Oil exhaust is hot and dry; it pushes up and out. Gas exhaust is cooler and produces water vapor as a byproduct of combustion. In a flue sized for oil, that moisture condenses inside the flue and pools. The result is a slow, invisible erosion of the mortar and tile from the inside. The crown is your first line of defense against exterior water adding to that problem. If the crown is cracked, the interior moisture problem compounds. In Hudson, where oil-to-gas conversion has been common for a decade, we inspect the crown, cap, and flue together before any appliance swap. That’s the only way to know if the flue can handle the change. Call for a free estimate (781) 390-9211.
Because the inspector needs proof that the flue you’re connecting is properly separated from the one next door. Hudson’s older homes commonly have two or three flues sharing one brick stack, serving different units or different appliances. Over 100 years of use, mortar joints degrade and flue tiles crack. An untraced flue might look fine but leak exhaust into an adjacent cavity. The code requires each flue be individually identified, documented, and confirmed as separated before any new wood insert is legal. We camera every flue, show you the footage, and give you a plain-English verdict on what it means. When we replaced a multi-flue cap and rebuilt the crown on a late-1800s worker’s cottage near downtown Hudson, we installed an Olympia Chimney custom stainless multi-flue cap, applied a Gelco crown coat after repairing the wash, and traced each flue individually. The homeowner connected the gas insert the same week the inspector signed off. That’s the right order of operations.
One More Thing About Hudson’s Shared Chimney Stacks
Here’s something no generic chimney page will tell you. Hudson’s dense historic core is full of late-1800s worker housing built during the shoe-manufacturing boom. Those homes were built with chimneys that serve two or three flues on a single stack, often shared between attached or closely spaced units. A deteriorated crown on that shared stack lets water migrate into every flue simultaneously. You can’t see it from the street. You can’t see it from the attic. But that water is freezing and thawing inside the masonry all winter, spalling the mortar and cracking the tile. Then your neighbor’s gas exhaust starts smelling like it’s in your living room, and you don’t know why. This is the single most common multi-unit chimney problem we see in Hudson, and it’s almost always preventable with the right cap and a sound crown. We trace every flue, we document the separation, and we show you the camera footage. No exceptions.
If you’re in Hudson and you haven’t had the crown and cap looked at in the last few years, call Wendell at (781) 390-9211. Free estimate, straight answer, no pressure. If the job doesn’t need doing, he’ll tell you that too.
