Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Trusted Chimney Repair for Yonkers Homeowners
Chimney repair in Yonkers almost always comes down to one of five things: a cracked crown, failed flashing, a damaged liner, spalling brick, or a missing cap. Each one lets water into places it shouldn’t be, and water is what turns a $400 fix into a $4,000 rebuild. Hadley Chimney Yonkers has been fixing chimneys across Westchester since 2003, and we’ve seen every variation of these problems in homes from Riverdale to Scarsdale. Our technicians arrive in a tracked window, show you photos of exactly what’s wrong before touching anything, and hand you a written price so you know the cost before work begins. Cory Mitchell leads our Yonkers team with the same approach he’s used for over twenty years: explain the trade term, show the proof, fix it right. Call (914) 233-3156 and a live person answers, any hour.
Chimney Cap Installation
Chimney Cap Installation is the single most cost-effective way to keep water, animals, and debris out of your flue. We install stainless steel and copper caps sized to your specific flue tile, with a screened mesh that keeps birds and squirrels out while still allowing proper draft. In Yonkers, where raccoons and squirrels are common in neighborhoods like Crestwood and Park Hill, a missing cap is an open invitation. Most cap installations run between $250 and $600 depending on the cap material, flue size, and roof access.
Why the Right Cap Size Matters
A cap that’s too small chokes the draft. A cap that’s too big lets rain blow in sideways. We measure the flue opening on site and match the cap to within a half inch.
Materials We Recommend
Stainless steel caps outlast galvanized by 5 to 10 years in Yonkers’ freeze-thaw winters. Copper caps cost more upfront but develop a patina that many homeowners on the east side of the city specifically request.
Styles & brands we work with
Chimney Cap Replacement
Chimney Cap Replacement is necessary when your existing cap has rusted through, blown off in a storm, or been torn apart by an animal trying to get in. We see bent and corroded caps regularly in Yonkers, especially on older brick chimneys in Ludlow and Dunwoodie where the original caps were installed in the 1970s and 80s. A replacement typically costs $200 to $500, less than installing a cap where none existed because the flue is already measured and accessible.
When Replacement Beats Repair
If the mesh is ripped or the cap body has rust holes, patching it is a losing game. A new cap costs about the same as an hour of labor and lasts 15 to 20 years.
What We Check Before Replacing
We inspect the flue tile underneath before swapping the cap. If the tile is cracked or spalling, that changes the recommendation, and we’ll show you photos before recommending anything further.
Chimney Liner Installation
Chimney Liner Installation becomes necessary when your existing clay tile liner has cracked, separated, or deteriorated to the point where exhaust gases can leak into the home or heat can reach combustible materials. Hadley Chimney Yonkers installs DuraFlex stainless steel liners and HeatShield ceramic repair systems, both of which are built for decades of service. In older Yonkers housing stock, including pre-war homes in Lincoln Park and Runyon Heights, original clay liners are often beyond what a patch can fix. Full liner installation generally runs $2,500 to $6,000 depending on flue length, accessibility, and whether insulation is required.
DuraFlex Stainless Steel Liners
These are the gold standard for wood-burning fireplaces and oil or gas furnaces. They’re UL-listed, flexible enough to route around offsets in masonry, and we stock the most common diameters on our trucks.
HeatShield as a Lower-Cost Option
When the masonry structure is sound but the clay liner has gaps or cracks, HeatShield’s cerfractory coating can restore the liner without a full tear-out. It costs roughly 40-50% less than a full stainless liner and carries a 20-year warranty.
Chimney Flashing Repair
Chimney Flashing Repair addresses the metal barrier where your chimney meets the roofline, which is the most common source of chimney-related leaks in Yonkers. Flashing gets damaged by ice dams, rust, improper original installation, and the freeze-thaw cycle that hits Westchester every winter. A proper flashing repair involves removing the old material, cutting a reglet into the mortar, and installing new step and counter flashing. Typical flashing repairs run $400 to $900 in Yonkers, more if the roof itself needs spot repair around the flashing.
Signs Your Flashing Is Failing
Water stains on the ceiling near the fireplace, damp drywall in the attic, or visible rust and pulled-away metal at the roofline. By the time you see interior staining, the flashing has usually been leaking for months.
What Proper Flashing Looks Like
Two layers: step flashing that goes under each shingle course and counter flashing embedded into the mortar joint. If someone just caulks over old flashing, it will leak again within a year. We cut the reglet and do it right.
Chimney Crown Repair
Chimney Crown Repair fixes the concrete or mortar slab that seals the top of your chimney and sheds water away from the flue. Yonkers winters are brutal on crowns because water seeps into hairline cracks, freezes, and expands. A cracked crown lets water run down the inside of the chimney, which is how you end up with spalling brick and liner damage that costs ten times more to fix. Crown repair or replacement runs $700 to $1,500 in Yonkers depending on the size of the chimney and the extent of the cracking.
Why Caulk Fails
We see silicone and roof cement shoved into crown cracks constantly. It fails in a season. The right fix is either a proper crown patch using elastomeric material or a full recast with a proper overhang.
Crown Coating We Trust
We use Gelco and Olympia Chimney crown-coat products, which are made specifically for masonry chimneys and flex with temperature swings instead of cracking.
Chimney Repair Companies
Chimney Repair Companies in Yonkers range from single-truck operations to HVAC firms that do chimneys on the side. What separates a real chimney company is what they show you. Hadley Chimney Yonkers is one of the few chimney repair companies in Westchester that provides before-and-after photo documentation of every repair and a written guarantee on every job. We’re part of the Relay Home Co. family, and every visit is held to the Relay Visibility Guarantee: live arrival tracking, a written price before work starts, and digital invoicing you can pay from your phone.
What to Ask Any Chimney Repair Company
Ask if they’ll show you photos of the damage before you approve work. Ask if the price on the quote is the final price. Ask if the guarantee is written. If any answer is vague, keep looking.
How We’re Different
Our technicians are background-checked and uniformed. Calls are answered by a live person around the clock. And if a repair fails within 365 days, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and it’s not a promotion.
Chimney Masonry Repair
Chimney Masonry Repair covers the brick and mortar structure of your chimney: repointing deteriorated joints, replacing spalled bricks, and rebuilding sections that have shifted or crumbled. Yonkers has thousands of brick chimneys built between 1900 and 1980, and many of them are now showing their age. Repointing typically runs $15 to $30 per square foot, full brick replacement runs $50 to $100 per brick, and partial rebuilds can run $1,000 to $5,000 depending on how much of the chimney needs to come down.
Spalling Brick and Freeze-Thaw Damage
Spalling happens when water penetrates the brick face and freezes, popping the outer layer off. Once spalling starts, it accelerates because the softer inner brick absorbs even more water.
Matching Mortar Matters More Than You Think
Old chimneys were built with lime mortar, not Portland cement. Using the wrong mortar on an old brick chimney can trap moisture and destroy the brick. We match the mortar type to the age of your home.
Brands We Service
We work with HeatShield ceramic repair systems on a regular basis, including both the resurfacing and joint repair kits. Our technicians are trained on proper surface preparation and application, because a HeatShield repair is only as good as the bond underneath it. We’ve used Gelco crown sealants and waterproofing products for years and stock their most common formulas on our service vehicles. Olympia Chimney supplies many of the caps, dampers, and accessories we install. Famco products cross our path regularly on multi-flue commercial and larger residential chimneys, and we’re familiar with their specific sizing requirements.
Whether you have a HeatShield-lined flue, an Olympia Chimney cap, or any other make, we can service it. We don’t push a brand because it’s on the truck; we recommend what fits your chimney and your budget.

AfterSigns You Need a Pro Right Now
- White staining on the exterior brick (efflorescence) – This means water is moving through the masonry and leaving salt deposits behind. It’s a clear indicator that water has been penetrating the chimney for a while, and the internal damage is usually worse than what you see.
- Bits of tile or brick in the firebox – If pieces of the flue liner are falling into your firebox, the liner has deteriorated to the point of failure. Every fire you build after this point is sending heat and exhaust gases into areas of your chimney that were never designed to handle them.
- Water in the firebox after rain – Rain coming straight down the flue means the cap is missing or damaged. Water running down the fireplace walls or showing up near the ceiling means the flashing or crown has failed. Both are fixable now and expensive later.
- A smell like a campfire in the house, even when the fireplace hasn’t been used in days – This is usually creosote off-gassing or a drafting problem. It can also mean exhaust from a furnace or water heater is being pulled back into the house instead of venting out.
- Rust on the damper or firebox walls – Rust means ongoing moisture exposure. In a chimney, moisture plus heat equals accelerated masonry failure. If the damper is rusted, the chimney has been wet for an extended period.
Our Process, Step by Step

We inspect everything from the roof down. Your technician checks the crown, cap, flashing, exterior masonry, flue liner, damper, firebox, and smoke chamber. We use camera inspection tools to see the full length of the flue liner, not just what’s visible from the top.
- 3

How Much Does Chimney Repair Cost in Yonkers?
Chimney repair costs in Yonkers depend on what’s broken and how far the damage has spread. A simple cap replacement runs $200 to $500. Flashing repair typically lands between $400 and $900. Crown repair or recasting runs $700 to $1,500. A full stainless steel liner installation runs $2,500 to $6,000, while a HeatShield liner restoration usually costs 40-50% less. Masonry repointing runs $15 to $30 per square foot. We price every job with a written estimate before any work starts, so you’re never guessing.
What affects the price the most is access. A chimney on a steep roof in a neighborhood like Beech Hill or Armour Villa costs more to work on safely than one on a low-pitch roof. The other factor is how long the problem has been ignored. We see chimneys where a $400 flashing repair would have solved everything five years ago, but the water has since destroyed the liner and the crown, pushing the total past $5,000.
How do you avoid overpaying? Get a camera inspection. Ask for photos. If a company won’t show you what they’re fixing, you can’t verify the work. Our free estimates include the inspection, the photos, and a written quote. If we tell you something can safely wait, we’ll say so.
