Fast, Reliable Chimney Repair Across Westbury
Chimney repair in Westbury usually falls into one of two buckets: water getting in where it shouldn’t, or decades of heat and salt air breaking down mortar, brick, and metal components. Most Westbury homeowners wait until they see a stain on the ceiling or smell smoke backing into the living room before they call. By then the repair is rarely a one-hour fix. Flint Chimney Co Hempstead sends background-checked, uniformed technicians to Westbury with written pricing delivered before any work starts. Call (516) 559-6922 and you’ll get a live person, not a voicemail tree.
We’ve worked on enough split-levels off Old Country Road and colonials near the Westbury Golf Club to know what this housing stock does to a chimney over 60 or 70 years. The masonry is original. The flashing is original. The crown was poured when Eisenhower was president. Salt air from the South Shore works its way into every seam and crack. Freeze-thaw cycles do the rest.
Why Flint Chimney Co Hempstead Is Westbury’s Preferred Chimney Repair Company
We’ve been part of the Garrison Partners family since 2002, and the way we run calls in Westbury follows the same discipline on every job: written price first, written guarantee second, work that’s done right or we come back at no charge under the 365-Day Done Right Promise.

If we’re recommending a liner replacement or crown rebuild, we show you the images before we ever hand you a quote. Our Chimney Repair operation runs on documentation, not persuasion.

Chimney Flashing Repair in Westbury
Chimney flashing repair in Westbury addresses the metal transition where the roofline meets the chimney masonry, and it’s the single most common water-intrusion repair we perform in this town. The original aluminum flashing on 1940s and 1950s homes gets eaten by salt air over time. Pinholes develop at the corners, especially on the side of the chimney facing the prevailing nor’easter winds. You’ll see brown stains on the drywall around the firebox, or peeling paint on the ceiling near the chimney chase. The fix is not caulk. Caulk fails in one season. The fix is replacing the flashing with stainless step flashing and counter-flashing, properly lapped and mechanically fastened, then sealed with a quality polyurethane sealant from a brand like Copperfield.
Step flashing replacement on split-levels
Split-levels in Westbury present a specific challenge because the roofline intersects the chimney at odd angles. The flashing detail has to be custom-bent on site to follow the pitch. A standard flashing repair in Westbury runs $400 to $900 depending on how many sides of the chimney are exposed and whether the existing flashing needs to be completely torn out or can be selectively replaced.
When flashing repair isn’t enough
Sometimes we get called out for flashing and find the problem is actually a cracked crown letting water run behind the flashing from above. That’s why our inspection before any Westbury flashing job includes a crown check. We’d rather tell you the crown is the root cause and price both correctly than patch the flashing and come back in March.
Chimney Crown Repair in Westbury
Chimney crown repair in Westbury means rebuilding the concrete cap that covers the top of the chimney’s masonry, and on Long Island it’s a repair that cannot wait. The crown’s job is to shed water away from the flue and the brick. When a crown was poured badly, with no overhang or drip edge, water runs straight down the face of the brick. In Westbury’s freeze-thaw cycles that water freezes, expands, and pops mortar joints and brick faces. The result is spalling brick and, eventually, a chimney that leaks from the top down. A crown rebuild in Westbury typically runs $800 to $1,400, which includes removing the old crown, form-pouring a new one with proper slope, a 2-inch overhang, and a drip edge.
Cast-in-place crowns versus pre-cast caps
For most Westbury chimneys, we pour the crown on site so it matches the exact dimensions of the flue and masonry. Pre-cast caps are cheaper but rarely fit the odd sizes found on mid-century chimneys here, and a bad fit is a built-in leak. Gelco and Olympia Chimney make excellent pre-cast products for straightforward applications, but most Westbury jobs get a custom pour.
The salt-air connection
Salt accelerates crown failure. It wicks into the porous concrete, crystallizes, and pops the surface. That’s why we always recommend sealing a new crown with a breathable siloxane-based masonry sealer after it’s cured. It costs a little extra and buys years.
Trusted Brands We Service in Westbury
When a Westbury repair calls for new materials, we specify what’s actually going on that chimney, not what’s on the truck. That means Gelco flexible liners for oil-fired flues, Olympia Chimney caps and dampers for replacements, and Famco termination caps where the job calls for a galvanized-to-stainless upgrade. We stock common sizes locally so a typical flashing or cap replacement in Westbury doesn’t sit waiting on a parts order. Stainless is the standard recommendation for any exterior metal component on a Westbury chimney. It costs more than galvanized up front, but it outlasts galvanized by decades in salt air.

AfterCommon Chimney Repair Problems We See in Westbury Homes
- Rusted galvanized caps. Salt air eats galvanized steel at the seams within three to five years. Once the cap rusts through, rain and snow melt wash straight down the flue onto the damper and firebox floor.
- Spalled brick and failed mortar joints. Freeze-thaw cycling on 60-year-old brick with original lime mortar means joints turn to sand and brick faces pop off. Repointing with the correct mortar type stops it from spreading.
- Failed crowns and cracked flue liners. Unsealed crowns let water behind the flue, and the water freezes. We routinely pull cracked clay tile chips out of smoke chambers in Westbury homes.
- Flashing pinholes and roof leaks. Aluminum flashing on nor’easter-facing slopes develops pinhole corrosion at the corners. Homeowners see ceiling stains long before they see the flashing.

FAQs About Chimney Repair in Westbury
Westbury sits close enough to the South Shore that marine air pushes inland on prevailing winds, and that salt spray settles directly on metal chimney components. Galvanized steel caps are zinc-coated, and once the zinc coating is compromised at a seam or scratch, the underlying steel rusts through quickly. Inland towns like Hicksville get the same weather system but far less salt deposition. The fix is a stainless cap from a manufacturer like Olympia Chimney or Famco, which outlasts galvanized by decades. Cost to replace: $350 to $650 installed. Call (516) 559-6922 for an exact quote.
The first sign is usually a draft problem: your oil burner short-cycles, the fireplace doesn’t draw, or you smell oil fumes near the flue after the burner kicks off. Spalled clay chips at the bottom of the smoke chamber or in the clean-out are a definitive sign. We can’t confirm a crack without a camera inspection, which is why our camera the flue on every Westbury repair call where a liner issue is suspected. Liner replacement with a Gelco flexible liner runs $1,800 to $3,200 for a typical Westbury split-level. Call us for a camera inspection and written quote.
Typically the cap goes first, then the crown, then the flashing. Galvanized caps start rusting at the seams within three to five years of salt exposure. A failed cap lets water and snow melt fall straight down the flue, which accelerates every other problem the chimney has. Once the cap is gone, water sits on the crown and wicks into the brick. If you have a galvanized cap on a Westbury chimney and you haven’t looked at it in five years, now is the time.
Yes. The original crowns on 1940s and 1950s Westbury homes were often poured with no overhang and no drip edge, which means water tracks straight down the brick face every time it rains. Add freeze-thaw cycles and salt wicking, and a crown that should last 30 years might last 15. If your home still has its original crown, it has already outlived its useful life. A proper crown rebuild with overhang and drip edge costs $800 to $1,400. Call (516) 559-6922 and we’ll tell you if your crown actually needs it, with photos to show you why.
Yes. Salt corrosion can eat through metal chimney components and crack clay flue liners even when there’s no creosote buildup. A cracked liner disrupts the draft by letting air leak into the flue cavity, and rusted-out dampers can warp and restrict airflow. On a split-level off Powells Lane, we found a galvanized cap rusted through after three winters of salt spray, with the clay flue liner cracked at the top two courses from freeze-thaw cycling behind a failed crown. We replaced the cap with a stainless DuraFlex model, rebuilt the crown with a proper overhang and drip edge, and installed a Gelco flexible liner to restore draft before the oil burner’s next ignition cycle. If your fireplace suddenly draws poorly in a house that burned fine for years, salt is a suspect.
