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 Repair Across Yonkers
Chimney repair in Yonkers typically runs $350-$2,800 depending on whether you need mortar repointing, flashing replacement, flue liner work, or a partial rebuild. Most repairs on pre-1930 rowhouses in Nodine Hill, Park Hill, and southwest Yonkers are finished the same day. If you’re seeing spalling brick, a leaking crown, or water stains near the party wall, call (551) 212-3526 for a written estimate before any work starts.
We know Yonkers chimneys because we work on them every week. The attached brick rowhouses, the shared stacks, the oversized coal-era flues now venting high-efficiency gas boilers. That’s the job. Our crews are background-checked, uniformed, and assigned a named tech who texts when they’re on the way. Corrine Halstead runs our Yonkers operation, and every job gets a Level 2 camera-scan inspection with a documented photo record before anything is quoted.
Why Level Two Chimney Yonkers Is Yonkers’s Preferred Chimney Repair Company
We’ve inspected and cleaned more than 38,000 chimneys since 2009, and Yonkers accounts for a large share of that number. Every one of those jobs started with a written price, a written scope, and a written warranty delivered before work began. Haven Standard Clause 1: have it in writing. That’s not a slogan, it’s how we operate in Yonkers.
Our reputation in Yonkers is built on evidence. After every repair, you get a documented photo record: the liner condition, the crown before and after, the flashing at the parapet. We don’t ask you to trust us. We show you. Corrine Halstead has built the Yonkers team around that principle, and it’s why homeowners in neighborhoods from Getty Square to Dunwoodie keep our number.
Response time to Yonkers is usually one to three business days for non-emergency repairs. If you have water actively entering the chimney or a suspected carbon monoxide issue from a shared flue, we prioritize the call. Our dispatch is coordinated from our New York City office; crews serve Yonkers locally.
Our Chimney Repair Services in Yonkers
Here’s what we actually do in Yonkers homes, in plain terms.
Mortar Repointing
Yonkers rowhouses built before 1930 used lime-based mortar. Over decades of Hudson River Valley freeze-thaw cycles, that mortar softens, crumbles, and falls out of the joints. Repointing in Yonkers runs $25-$45 per square foot of masonry surface. We match the mortar color and composition to your original brick, because a mismatched Portland cement patch on a 1923 rowhouse looks wrong and traps moisture.
Spalling Brick Repair
Spalling is when the brick face flakes or pops off due to trapped water freezing and expanding. Yonkers’s exposed rooftops along the riverfront accelerate this, especially on the northwest-facing walls. Spalling brick repair typically runs $60-$120 per brick replaced, including cutting out the damaged unit and setting a matched replacement. If the spalling is widespread across half the stack, a rebuild may be cheaper than piecemeal replacement.
Chimney Waterproofing
Waterproofing in Yonkers is not paint. We apply a vapor-permeable siloxane treatment that lets moisture escape while blocking rain penetration. On pre-1930 brick, this matters because dense sealants trap water and worsen spalling. Chimney waterproofing in Yonkers runs $450-$900 for a typical two-flue rowhouse stack. It’s one of the cheapest repairs we do relative to the damage it prevents.
Flashing Repair
Flashing is the sheet metal where the chimney meets the roof. On Yonkers attached rowhouses, the flashing often spans a party wall junction, which means a leak at that point damages two homes. Flashing repair or replacement in Yonkers runs $350-$850 depending on access and the extent of the existing flashing. If the roof access requires working from a shared parapet, we coordinate with the neighbor before any work begins.

BeforeAfterTrusted Brands We Service in Yonkers
We install and repair Chimney Repair systems using materials from DuraFlex, HeatShield, and Olympia Chimney. These are not off-brand parts. DuraFlex and Olympia liners hold up to the acidic condensation we routinely find in Yonkers’s oversized coal-era flues. HeatShield is our go-to for resurfacing damaged terra cotta liners without a full rebuild. Because we stock these locally for Yonkers jobs, turnaround on liner work is days, not weeks.
Common Chimney Repair Problems We See in Yonkers Homes
- Cross-contamination in shared stacks: In attached rowhouse blocks, your neighbor’s boiler or water heater may vent into an unlined shared flue, pushing carbon monoxide and acidic moisture into your home. This shows up as discolored brick, a corroded damper, or a smell of exhaust inside. We map the flues before any repair.
- Oversized coal-era flues on modern gas boilers: A flue built for a coal furnace in 1925 is far too large for a high-efficiency gas boiler. The exhaust cools too quickly, condenses, and forms an acidic glaze that eats terra cotta liner tiles. This is the single most common cause of liner failure in Yonkers.
- Botched flashing at the party wall: Roof access on attached rowhouses often means working from a narrow shared parapet. When flashing is skipped or done poorly, water enters at the roof line and travels down along the shared wall. By the time you see a stain on the ceiling, the damage is already done.
- Crown failure from freeze-thaw cycling: The Hudson River Valley corridor funnels sharp winter winds across Yonkers rooftops. Water seeps into hairline crown cracks, freezes, and wedges the crack wider. Within a few seasons, you need a full crown rebuild instead of a simple seal.

Flue mapping is billable when it’s required for a permit (Yonkers building department requires correct flue identification on permits), and we include that documentation in every estimate. Estimates are free. Call (551) 212-3526 and we’ll send a tech with a camera, not a guess.
We Also Serve Cities Near Yonkers
Our Yonkers crews regularly work in Mount Vernon, Eastchester, New Rochelle, and Scarsdale. The housing stock changes quickly once you leave the rowhouse blocks, and so do the repair needs.

FAQs - Chimney Repair in Yonkers
You have us map it. We lower a camera down each flue while you’re home, verify the visual path, and cross-reference that against what’s venting where. In Yonkers, the building department requires correct flue identification on permits, so this step is not optional when the work is permitted. We include the mapping documentation with every estimate. Call (551) 212-3526 to schedule it.
The flue is too big. Your chimney was built for a coal furnace that produced hot, high-volume exhaust. A modern gas boiler produces cool, low-volume exhaust. In that oversized flue, the exhaust cools below the dew point before it exits, condenses, and forms an acidic glaze that dissolves terra cotta tile from the inside. The fix is a correctly sized liner, usually DuraFlex or Olympia. This is the most common repair we do in Yonkers rowhouses, period.
If you smell exhaust inside, see corrosion on your damper, or have a carbon monoxide detector that trips intermittently, the answer may be yes. Shared stacks in pre-1930 Yonkers rowhouses often have multiple flues with no liner separating them. A neighbor’s appliance exhaust can enter your home through shared vertical runs. We isolate and reline your flue to end the cross-contamination. Call (551) 212-3526 and describe the symptoms.
In most cases, both owners are responsible, but the specific answer depends on Yonkers’s local building code and the governing HOA or party wall agreement if one exists. What we can do is document the condition with a camera scan and photos, identify which flue belongs to which unit, and give you a written scope you can share with your neighbor or an attorney. The documentation alone often resolves the dispute. Call (551) 212-3526 for a free estimate on the inspection.
Sometimes. If the brick is sound and only the mortar is deteriorated, repointing is sufficient and costs $25-$45 per square foot. But if the crown is cracked, the liner is compromised, or the spalling is widespread, repointing is a band-aid. We’ll show you photos of what’s actually wrong and tell you plainly if a rebuild is the right call. If it can wait, we’ll say that too. Call (551) 212-3526 for an honest assessment.
For a written estimate on chimney repair in Yonkers, call (551) 212-3526. Our phones are answered by a live person, 24/7. A named technician will be assigned to your job, and you’ll get a text when they’re on the way. If we’ve given you a quote, that’s the price. No add-ons, no surprises.
