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.

Our Chimney Cap & Crown Services in Mount Vernon
Cap Installation
A properly fitted cap keeps rain, leaves, birds, and stray baseballs out of your flue. In Mount Vernon, where attached homes often share a single brick chase with separate flues for each unit, cap installation gets more complicated than the average suburban house. We measure each flue individually and make sure the cap is sized so it doesn’t shift under wind load and block draft in your neighbor’s side. Standard single-flue cap installation in Mount Vernon runs $185-$320. Multi-flue caps on shared chases typically run $340-$600 depending on chase size and flue count.
Cap Replacement
Rusted-out caps on Mount Vernon row houses are one of the most common calls we get, especially after a hard Westchester winter. When a cap rusts through on a shared chase, rainwater pours down every flue in that stack, not just yours. We see it all the time near the South Side blocks off South Fulton Avenue. Replacement is straightforward: we pull the old cap, inspect the flue tile beneath it, and install a new one that fits the existing crown. Most replacements are finished in under two hours. Prices run $195-$385 for single-flue replacements and $360-$650 for multi-flue setups.
Crown Repair
The chimney crown is the concrete slab or mortar top that seals off the brick. On Mount Vernon’s 90-to-120-year-old chases, crowns are often original, cracked, and letting water seep behind the brick face. That water freezes and thaws through the winter, spalling the brick and opening lateral cracks between flues. We repair crowns with proper crown cement, not roofing tar. Minor crack repair starts around $225. A full crown rebuild on a row-house chase runs $450-$800, depending on chase size and how much of the old crown has to be chiseled out. Crown repair is the single best investment most Mount Vernon homeowners can make in their chimney, because a sound crown prevents most of the other problems from starting.
Crown Coating
Crown coating is a flexible, waterproof membrane we apply over the existing crown to seal hairline cracks before they become structural. On older Mount Vernon brick chases, we often recommend a Gelco crown coat after a rebuild or as a preventative measure on a crown that’s still sound but showing surface wear. Coating runs $150-$300 on a typical single-family chase and $250-$425 on a shared multi-flue chase. It’s not a substitute for rebuilding a badly deteriorated crown, and we’ll tell you plainly when the crown has passed the point where coating makes sense.

Trusted Brands We Service in Mount Vernon
We install and service caps and crowns from Copperfield, Gelco, and Olympia Chimney. These aren’t off-brand imports. Copperfield makes the multi-flue caps we use on Mount Vernon’s shared row-house chases. Gelco’s crown coat is what we apply to seal older crowns before they crack through. We keep common sizes and materials stocked, which means less waiting when your cap needs replacing in the middle of a rainy week. If you’ve got a written estimate from another company, bring it to us. We’ll give you a free second opinion, and we’ll match or beat it when it’s apples to apples.
Common Chimney Cap & Crown Problems We See in Mount Vernon Homes
- Rusted multi-flue caps on shared chases. When one cap rusts through on a South Side row house, rain enters every flue in that stack. The water accelerates liner collapse, and we routinely find cross-flue gas migration in these cases because combustion gases follow the path the water opened up.
- Spalled brick crowns on pre-1930 chases. The freeze-thaw cycle in Westchester County pushes temperatures across 32°F dozens of times each winter. That repeated expansion and contraction spalls the exposed brick and mortar on Mount Vernon’s century-old chases faster than almost anywhere else in the county.
- Undersized or unsecured caps that shift in wind. On attached homes with a shared chase, an improperly fitted cap doesn’t just affect your draft. It can block the adjacent unit’s flue entirely, pushing combustion gases back into your neighbor’s living space. We size and secure every cap for the specific chase it’s going on.
- Cracked crowns that go undetected for years. Because so many Mount Vernon chimneys are shared, homeowners often assume a draft problem is just their issue. But a cracked crown on the party wall can let water into both flues simultaneously. By the time anyone notices, the liners in both units may need work.

FAQs - Chimney Cap & Crown in Mount Vernon
Yes, and here’s why. On Mount Vernon’s attached and semi-attached homes, a single brick chase often contains separate flues for two or more units. A drafting problem in your flue almost always has a cause in the chase itself, not just in your flue. We’ve found collapsed liner debris from a neighbor’s flue blocking another unit’s draft, cracked crowns letting water into every flue in the stack, and rusted caps that shifted and sealed off the wrong flue. The only way to know is a whole-chase inspection, which is what we do as standard on every shared-chase job. Call (914) 537-6479 and we’ll set it up.
A cracked crown lets water enter the chase, and that water does two things. It cools the flue gases in adjacent flues, causing creosote to condense and stick to the walls faster than it would in a dry chase. And it erodes the mortar joints between flue tiles, which lets smoke and gases leak sideways and settle in the same damp, low-draft conditions that accelerate creosote formation. On Mount Vernon row houses where two or three flues share a chase, one bad crown can compromise every adjacent flue. Crown repair or coating stops the water, and the creosote problem you see in your chimney gets its root cause fixed at the same time.
Yes, but it requires correct sizing and placement for every flue in the chase, not just yours. We fabricate and install custom multi-flue caps from Copperfield that are built to the exact dimensions of the chase and positioned so each flue keeps its proper draw. A generic cap slapped on top can shift in wind and block an adjacent flue. That’s a carbon monoxide risk for your neighbor’s unit, not just an inconvenience. We measure, we check clearances, and we verify draft on every flue before we leave the roof.
The risk is that rain keeps pouring into the shared chase every time it storms, and every one of those wet days moves the liner in every attached unit closer to collapse. On the tightly packed South Side blocks, when one flue’s liner collapses, debris and combustion gases can migrate laterally into neighboring flues. What starts as a $350 cap replacement becomes a $4,000-plus relining job across two units. If your cap is rusted through, don’t wait. Call (914) 537-6479 for a free estimate, and we’ll tell you honestly whether it needs doing this month or can wait a season.
Because the housing stock is older and denser. The vast majority of Mount Vernon’s chimneys were built between 1890 and 1930, with original brick and mortar that’s now 90 to 130 years old. Westchester’s winter freeze-thaw cycle stresses that masonry every year, and attached homes share the load: a crown failure on one unit affects every flue in the chase. Newer detached homes in White Plains or Harrison have younger masonry, single-family chases, and fewer shared walls. That’s why we apply Gelco crown coat on Mount Vernon chases more often, as a preventative measure before cracks open up. It’s cheap insurance on a structure that’s older than most of the people living around it.
