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 Yonkers
A chimney cap and crown replacement in Yonkers typically runs $450-$1,400 for the crown and $185-$640 for the cap, depending on the flue count, liner condition, and whether your home shares a chimney stack with a neighbor. Most jobs are completed in one visit once we document what’s there with a camera. If you’re in Yonkers, we know the housing stock: attached row houses, multi-flue stacks, and steep western streets that punish exposed brick. Call (980) 580-8641 for a written price before any work starts.
Here’s what matters for Yonkers specifically: much of the city was built between 1890 and 1935 as attached brick row houses and two-to-three-family homes. That means chimneys here rarely serve just one flue. Walk down any block off South Broadway or Nepperhan Avenue and you’ll see stacks carrying three, four, sometimes five separate flues inside a single brick chase. When a crown cracks on a shared stack, it’s not your problem alone. It’s everyone’s who vents into that masonry.
Why Emberly Chimney Cleaners Is Yonkers’s Preferred Chimney Cap & Crown Company
We’ve inspected chimneys on both sides of the Saw Mill River Parkway, from the steep streets below Nodine Hill to the flat grid east of Central Avenue. That matters because cap and crown problems look different depending on where in Yonkers you live. On the western slope near the Hudson, wind-driven moisture hammers west-facing crowns. On the eastern plateau, the bigger issue is aging brick joints and outdated flue sizing from 40-year-old heating equipment. Our Chimney Cap & Crown team documents every job with a camera before touching anything. Written price, written scope, written warranty. That’s Clause 1 of the Haven Standard, and we’ve worked that way since 2009.
Corrine Halstead leads our team, and she’s particular about one thing: nobody recommends a crown rebuild or cap replacement without camera evidence you can see. If the camera shows an intact crown and a solid flue, we’ll tell you the work can wait. 38,000+ chimneys inspected and cleaned since 2009, every one with a written price before work started and a photo record when it was done.
Our Chimney Cap & Crown Services in Yonkers
Cap Installation
A standard single-flue cap installation in Yonkers runs $185-$340. On row houses with multi-flue chases, you’re often looking at a custom multi-flue cap, which runs higher. We source caps from Olympia Chimney, Copperfield, and Gelco through our buying network to keep the price honest. Every cap is sized to the actual flue dimensions, not the “close enough” sizing that causes caps to fail in Yonkers wind.
Cap Replacement
Replacement typically falls between $210-$640 depending on flue count and whether the old cap’s mounting hardware left the flue crown needing repair. In Yonkers’s attached housing, we see a lot of caps rusted through at the base where the original was affixed directly to a cracked crown. We replace the cap and address the crown in the same visit.
Crown Repair
Crown repair in Yonkers generally runs $450-$1,100 depending on the extent of spalling and whether the flue liner joint needs resetting. This is where the city’s age shows. Many 1920s-era crowns in neighborhoods like Park Hill and Nodine Hill were poured without overhang or a drip edge. Water sits at the flue joint, freezes, and cracks the crown over a few hard Hudson Valley winters.
Crown Coating
Crown coating runs $300-$650 on most Yonkers homes. We use Gelco sealant after repairing the underlying crown surface. A coating alone won’t fix a crown that’s already cracked through, and we won’t sell you one if the camera shows structural failure. What you get is what the camera shows us, plus a written record of it.

BeforeAfterTrusted Brands We Service in Yonkers
Yonkers chimneys carry a mix of original 1920s tile, sleeved aluminum liners from 1980s conversions, and newer stainless from the current oil-to-gas wave. That mix means we stock parts accordingly. We keep Copperfield multi-flue caps, DuraFlex liner components, and Gelco crown sealant ready for Yonkers jobs so we’re not waiting a week on a part from a warehouse. If your stack feeds multiple units and you need a custom cap with divider plates, we fabricate it locally rather than shipping it in.
Common Chimney Cap & Crown Problems We See in Yonkers Homes
- Shared flue cross-contamination. In attached row houses across Park Hill, Nodine Hill, and the Getty Square corridor, a cracked crown on a shared chase lets exhaust from one unit’s gas appliance backdraft into a neighbor’s flue. It takes a camera scope of each individual flue to identify this, which is why we include it on every visit under Clause 4 of the Haven Standard.
- Freeze-thaw crown failure. Yonkers sits on the east bank of the Hudson and gets the full force of valley freeze-thaw cycles. Original lime-based mortar crowns from the 1920s weren’t built for this many cycles. Water enters, expands, and spalls the crown surface within a few winters.
- Topographic wind shadow downdrafts. For homes below the Nodine Hill bluff on the western end of the city, chronic downdraft failures are common because the ridge traps and redirects wind. A cap that works on the plateau can be nearly nonfunctional two blocks downhill. This is not an exaggeration; it’s something we’ve verified with camera footage and smoke tests on Tuckahoe Road-area homes.
- Oil-to-gas condensation damage. Yonkers is deep into an oil-to-gas conversion wave. Those original oversized brick flues sized for oil burners now run cool and condense. The acidic condensate eats at old mortar joints and crown surfaces. If you recently converted, your crown and cap need a check before next heating season.

FAQs - Chimney Cap & Crown in Yonkers
You won’t know without camera scoping each flue individually. The short answer: if you smell exhaust, see soot at wall penetrations, or your carbon monoxide detector reads elevated with your own appliance off but the neighbor’s running, you likely have a cross-contamination issue. We camera every individual flue in a shared stack, not just the one you think is yours. That’s how we confirm whether a cracked crown or missing cap is allowing backdraft between units. Call (980) 580-8641 for a written estimate.
Yes. Homes below the Nodine Hill bluff face a topographic wind shadow that causes downdrafts. Standard flat-mesh caps often make downdraft worse because they deflect wind unpredictably. A hooded vane cap or a custom cap with wind-deflecting geometry works better on those western-slope streets. The plateau east of Central Avenue doesn’t face this, so a standard cap is usually fine. We document the difference with onsite smoke tests.
The condensation from a smaller, cooler-burning gas appliance in an oversized flue creates acidic runoff that eats at the crown and the flue liner joint. We frequently find crown deterioration and efflorescence on Yonkers homes converted from oil to gas within the last five years, especially where the original flue crown wasn’t resized or coated. A crown inspection after conversion is not optional; it’s the difference between a $600 coating and a $1,900 rebuild.
Every 12 months. Occasional use means less heat in the flue, which means moisture lingers longer and does more damage. In Yonkers’s freeze-thaw climate, an unattended crown crack can widen significantly in a single winter. We’ll camera the flue, photograph the crown, and hand you the record. Same price whether you burn once a season or every week. Call (980) 580-8641.
Yes. A cracked crown in a shared chase compromises the entire masonry structure, not just the flue connected to your appliance. If your neighbor’s flue is below the crack and they run a boiler, exhaust can push into the wall cavity and find its way into your living space. This is exactly why we treat shared stacks as one system and camera every flue. Shared responsibility means shared documentation. We hand every unit owner a written record, not just the person who called us.
