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 Mount Vernon
Chimney cap and crown repair in Mount Vernon typically runs $285-$690 for a standard single-flue cap installation and $450-$1,200 for a crown repair with flexible coating, depending on whether your stack carries one flue or four. Most jobs on Mount Vernon’s attached brick rows involve shared stacks, so we start with a camera-scan Level 2 inspection to map exactly which flues are live, which are abandoned, and what the crown actually needs before we quote a dollar figure. Call (980) 580-8641 and we’ll get a named tech out to your block, usually within a few days.
Why Emberly Chimney Cleaners Is Mount Vernon’s Preferred Chimney Cap & Crown Company
Mount Vernon’s housing stock is dense, attached, and old. Most of it went up between 1900 and 1940, and the chimneys still standing from that era carry the history of coal-to-oil-to-gas conversions, abandoned flues, and decades of freeze-thaw chewing on lime mortar. We’ve worked enough row houses off South Fulton Avenue, along Gramatan, and up through Fleetwood to know that the cap and crown you need here isn’t the same one a detached colonial in Eastchester needs. Different stack configuration, different water path, different failure mode.
Emberly Chimney Cleaners operates under the Haven Standard, and since 2009 we’ve completed more than 38,000 chimney inspections and cleanings. Every one of them got a written price before work started, and every one ended with a photo record of what we found and what we did. That’s Clause 1 and Clause 4 of the Haven Standard, and we don’t work any other way. Corrine Halstead leads our team, and the crews we send into Mount Vernon are background-checked, uniformed, and carry their license information on the page. You should never have to take a chimney company’s word for what’s on your roof. With us, you see the photos.
We answer the phone 24/7 with a live person. No web form, no voicemail tag. When you’re standing in a Mount Vernon living room noticing backdraft on a cold night, you want to talk to someone who knows the difference between a collapsed flue liner and a misidentified neighbor’s flue. We do.
Our Chimney Cap & Crown Services in Mount Vernon
Cap Installation
A properly sized cap on the right flue stops rain, squirrels, and leaves from dropping into your chimney, but on a Mount Vernon attached-home stack, sizing only matters after we know which flue is yours. We map the stack first, then install. Standard single-flue stainless caps from Famco or Copperfield start around $285 installed. In a row where three units share one exterior stack, you’ll likely need a multi-flue cap, and we quote that on the spot after the camera work.
Cap Replacement
Rusted-out caps on Mount Vernon row houses are a regular sight from the sidewalk. Sheet metal screws give out, the mesh tears, and the whole assembly tilts off the flue tile. We carry replacement hardware for the common sizes and sell the replacement job as cap plus base screen, not cap plus mystery upsells. Replacement typically lands between $240 and $520, including removal of the old cap and a photo of the new one seated correctly.
Crown Repair
The crown is the concrete or mortar slab at the top of the chimney that sheds water off the brick. On Mount Vernon’s party-wall stacks, the crown is exposed full-duration to every freeze-thaw cycle, and first-degree spalling shows up as loose mortar chips on the roof below the stack. We clean out the failed material, re-form the crown with a slope that actually sheds water, and coat it with a flexible Gelco crown sealant that moves slightly with the brick. Crown repair on a single-family Mount Vernon chimney runs $450-$900; a four-flue row-house stack with significant spalling can reach $1,200.
Crown Coating
Crown coating is the stopgap that works when the crown is fully intact but has hairline cracks letting moisture into the top courses of brick. A flexible crown coat, like the Gelco product we stock for Mount Vernon work, bridges those cracks and buys years before full crown replacement is necessary. Typical coating job on a two-flue stack: $350-$650. If the camera shows the cracks are deeper than a surface fissure, we’ll tell you plainly and show you the frame where we saw it. Coating a failed crown is just spending money twice.

We stock and install caps and termination hardware from Famco and Copperfield, and use Gelco coating systems for crown work. Our Mount Vernon customers aren’t buying a brand name off a rack; they’re getting a specific material that fits the stack configuration we identified on the roof. When we need a Chimney Cap & Crown component that isn’t a standard size, we source it through the Haven buying network to keep the price honest and the turnaround reasonable for Mount Vernon work.
Common Chimney Cap & Crown Problems We See in Mount Vernon Homes
- Crossover exhaust in shared party-wall stacks. A cracked internal flue liner lets an upstairs neighbor’s gas combustion gases bleed into your fireplace flue. The result is carbon monoxide backdrafting into your living space, and no crown coating fixes it. You need a camera scan to find the breach and then a plan.
- Misidentified flues on multi-flue stacks. A worn crown on a four-flue stack gets “fixed” by capping only the visible flue while the neighbor’s active oil-to-gas flue stays open to rain, leaves, and animals. We identify which flue is which before anything gets capped. This is not optional in Mount Vernon.
- Freeze-thaw spalling above the roofline. The exposed brick above the roof is exactly where crown cracks admit water, and Westchester winter cycling spalls the face off those bricks fast. If it’s caught in first-degree, you’re repairing a crown. If it’s third-degree, you’re rebuilding masonry.
- Abandoned flues mistaken for active ones. Many Mount Vernon two- and three-family homes have a coal flue that hasn’t been used since the 1950s and an oil flue that’s been abandoned since a gas conversion. We tag them, cap them correctly, and document which one is which so the next owner doesn’t guess.

FAQs - Chimney Cap & Crown in Mount Vernon
We determine flue ownership with a Level 2 camera inspection, not a guess. On a shared stack, we identify each flue’s appliance source from inside your unit and trace it up. The neighbor’s flue is not yours to cap without permission; if we find their flue is open and failing, we’ll document it and leave the cap recommendation in the written scope so you can bring it to them. Call (980) 580-8641 and we’ll map it out and show you the footage.
Not a cap problem. That’s evidence of a compromised internal flue liner inside the shared stack, most likely. A gas conversion changes draft characteristics, and if the liner is cracked or missing between flues, their exhaust bleeds into yours when the gas burner kicks on. Our camera scan goes down the flue and shows exactly where the breach is; then we quote the repair in writing. Get it looked at if you smell exhaust; it’s not a nuisance, it’s a carbon monoxide exposure risk.
Yes. A row-house crown on a party-wall stack typically spans multiple flues and sits on brick that has been share-loaded by two buildings’ worth of thermal movement. Single-family crown repair is usually a straightforward re-form. On a Mount Vernon row house we assess the entire crown as one structural piece, because patching only your half leaves the neighbor’s half shedding water onto the same party wall. Our approach starts with a full-width crown evaluation, not a per-flue patch.
You can cap it, and often should, but only after we confirm it’s actually dead and disconnected. A “dead” flue that still vents a gas water heater or an abandoned oil appliance is not dead. If it’s genuinely sealed and abandoned, we cap it with a solid cover and document it so a future buyer isn’t guessing. Done right, that’s a $240-$400 job on most Mount Vernon stacks.
In most Mount Vernon attached homes, yes. Access from the roof is standard, and we can reach the stack with a ladder and roof kit without disrupting the neighbor or the sidewalk. Scaffolding only becomes necessary on tall, steep-pitched rooflines or when the rear stack is inaccessible from any roof plane. We’ll tell you during the inspection which access method applies to your exact block, and the written price includes whatever method we plan to use.
Emberly Chimney Cleaners serves Mount Vernon with caps and crowns that account for shared stacks, dead flues, and century-old brick. If you smell exhaust, see mortar chips on your roof deck, or just want the photo record of what’s actually on top of your house, call (980) 580-8641 for a free estimate. We’ll put the price in writing before anything gets touched.
