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 Alcott Chimney Sweep Is Yonkers’s Preferred Chimney Inspection Company
We’re not a crew that drives up from Manhattan assuming Yonkers chimneys work like Brooklyn brownstones. They don’t. The attached brick row houses in Park Hill, the two- and three-family homes climbing the hill in Nodine Hill, and the dense blocks of Southwest Yonkers were built between 1890 and 1940 for coal. Most of those flues were never properly relined when the buildings switched to oil, then gas. That’s the inspection we’re trained for, and it’s the one we do most.
Every Alcott technician passes a background check and identity verification before stepping onto your property. That’s the Threshold Standard, and it’s not an upgrade you pay extra for. When Ruben Castellano sends a technician to a Yonkers address, that person arrives in uniform, shows a photo ID badge at the door, and matches the name and photo you received before the visit. No exceptions. Homeowners who are alone, parents with young kids, older residents who want certainty about who’s coming through the door – that’s who we built this system for.
Our Chimney Inspection team includes camera-certified techs who’ve spent years working specifically on Westchester’s pre-war housing stock. We carry professional trade materials like DuraFlex and HeatShield, not box-store substitutes. And every inspection comes with a written price before any work starts. If a repair is needed, you’ll see the exact cost in writing first. No discoveries later, no surprise line items.
Level 2 Chimney Inspection in Yonkers
A Level 2 Chimney Inspection in Yonkers typically costs $349 to $489 and includes a full video scan of the flue interior using a camera system. This is the inspection that actually matters in Yonkers because most of the city’s housing stock predates modern liner requirements. A Level 1 visual check tells you what’s visible from the firebox and the roof. A Level 2 tells you what’s happening inside the flue walls, behind the brick, and beyond what any brush can reach. Given how many Yonkers chimneys are 80 to 130 years old and were never clay-tile relined, we recommend Level 2 for almost every home we’re called to.
Camera Scan and Shared Flue Assessment
We run the camera from the firebox or cleanout door up to the crown. In Yonkers’s attached two- and three-family homes, shared masonry stacks are common, so we check for cross-contamination between adjacent flues inside the same chimney. When a 1920s coal flue serves a modern gas boiler, it’s often oversized and under-lined, which creates weak draft and lets exhaust linger inside the flue. That’s exactly what a camera inspection documents.
When a Yonkers Homeowner Needs It
Buying or selling a home in Yonkers? A Level 2 inspection is required by many lenders and real estate contracts before closing, and for good reason. A property transfer is the moment a hidden flue defect becomes your problem. We also recommend Level 2 after any chimney fire, after a furnace or water heater conversion, or when you smell a sour, oily draft that comes and goes with appliance cycles. That smell often means exhaust is being pulled into the wrong flue.
Chimney Leak in Yonkers
A chimney leak in Yonkers is usually traced to one of three things: a cracked crown, failed flashing where the chimney meets the roofline, or spalled brick letting water soak into the masonry. Diagnosing the source correctly requires getting eyes on the full stack, not just applying sealant and hoping. Typical leak diagnosis and inspection runs $199 to $289, with common repairs like crown sealing or flashing replacement adding $350 to $800 depending on access. Hudson-facing ridgeline homes in Park Hill and Southwest Yonkers take moisture-laden wind year-round, which accelerates mortar erosion and makes cap and crown failures a recurring issue.
Water Entry and Freeze-Thaw Damage
Yonkers rises steeply from the Hudson River’s eastern bank. That elevation gradient exposes chimney stacks on western-facing ridgelines to strong, damp winds off the river through every season. When water soaks into aging brick and then freezes, the expansion spalls the masonry and opens new cracks for more water. A leak that looks minor in September becomes structural by February. We inspect the crown, the flashing, the brick surface, and the flue interior to find the actual entry point.
Shared Stack Leaks in Attached Homes
In a Yonkers row house, a leak in the shared chimney stack isn’t just your problem. Water entering through a cracked crown or spalled brick can travel down between flues and affect the neighboring unit too. We document what we find with photos and a written report so you have something concrete to share with an adjacent owner or a condo board. Nothing gets recommended without camera evidence you can see for yourself.
Trusted Brands We Service in Yonkers
We work with the materials chimney professionals specify, and we keep them on hand for Yonkers jobs so we’re not running back to a supply house mid-repair. That means DuraFlex liner systems for relining oversized coal-era flues, HeatShield for resurfacing damaged masonry where a full liner isn’t necessary, and Famco and Copperfield components for caps and terminations. When we recommend a liner or a crown repair, we tell you the exact brand we’re installing and why it’s the right fit for your chimney’s age and condition. A written guarantee covers every repair we make, and if that repair fails, the second visit is free.
Common Chimney Inspection Problems We See in Yonkers Homes
- Cross-contamination between shared flues. In attached two- and three-family brick homes, one unit’s boiler exhaust can pull into an adjacent flue serving a water heater or fireplace. The homeowner smells a sour, oily odor that comes and goes, and the cause is invisible without a Level 2 camera scan.
- Oversized, under-lined coal-era flues. Chimneys built for coal stoves between 1890 and 1940 were never sized for modern gas appliances. The flue is too wide, draft is weak, and first-degree creosote plus moisture collect where a brush can’t reach.
- River-driven crown and cap failure. Hudson-facing stacks in Park Hill and Southwest Yonkers take moisture-laden wind that eats mortar and spalls brick. A cracked crown or cap hides flue damage below, and freeze-thaw cycling makes it worse every winter.
- Code jurisdiction confusion near the Bronx line. Yonkers sits in Westchester County under NYS code, not NYC Building Code or FDNY rules. Homeowners near the city line often assume the stricter NYC inspection and relining standards apply to them. They don’t, and applying the wrong standard can mean either skipped work or unnecessary work.
Pricing for Chimney Inspection in Yonkers, NY
A standard Level 1 visual inspection in Yonkers runs $199 to $279. A Level 2 camera inspection runs $349 to $489, and that’s the one we recommend for most pre-war attached homes because of the shared-flue and under-lining issues we see constantly. A Level 3 inspection, which is needed when hidden damage is suspected behind walls or masonry, starts at $599 and involves opening access points. What affects your price? Roof pitch and access from tight streets like those climbing through Nodine Hill, the number of flues in a shared stack, and whether the chimney serves multiple appliances.

FAQs About Chimney Inspection in Yonkers
No. Yonkers is in Westchester County and follows New York State code, not NYC Building Code or FDNY rules. That means inspection and relining requirements that apply a few blocks south in the Bronx do not govern your Yonkers property. We know which standard applies to your address and inspect accordingly. If you’re unsure whether previous work on your chimney met the correct standard, call (336) 863-3889 and we’ll review it during your inspection.
It often is. Original coal-era flues in attached two- and three-family homes were almost never clay-tile relined when the buildings switched to gas. One flue serving a boiler and an adjacent flue serving a water heater can cross-contaminate through eroded mortar joints, pulling exhaust into the wrong living space. A Level 2 camera inspection documents exactly what’s happening inside the shared stack. Call (336) 863-3889 to schedule one.
A Level 2 inspection adds a full video scan of the flue interior, not just a visual look from the firebox and the roof. That camera reveals under-lined sections, deteriorated mortar joints, hidden blockages, and cross-contamination between shared flues – the exact issues Yonkers’s 1890s to 1940s housing stock produces. A basic yearly sweep-and-look will not find these. If your home was built before 1940 or has multiple appliances on one stack, get the Level 2. Call (336) 863-3889 for a free estimate.
Yes, though it’s a different form than the heavy tar you get from wood. Gas appliances produce a first-degree creosote that’s lighter and often mixes with moisture inside an oversized coal-era flue. It builds where brushes can’t reach, and it can contribute to draft failure. What’s more, a gas flue that’s never been relined may not be safely containing exhaust at all, and that’s a carbon monoxide risk. We check for this on every inspection, and if venting is compromised we’ll show you the camera footage. Call (336) 863-3889 to book.
Two reasons: age and exposure. Yonkers has a far older attached brick housing stock than Scarsdale or White Plains, and those pre-war stacks are already weak. Then the steep rise from the Hudson exposes western-facing ridgeline chimneys in Park Hill and Southwest Yonkers to constant moisture-laden wind that eats mortar and spalls brick. Freeze-thaw cycling does the rest. A cracked crown or failed flashing in Yonkers is a repetitive seasonal issue, not a one-time fix. If you’re seeing water stains or dampness near the chimney, call (336) 863-3889 and we’ll find the actual entry point.
