White Plains winters are hard on masonry. The freeze-thaw cycles we see from November through March push water deeper into brick and mortar every year, and by spring you’re looking at spalling faces, crumbling joints, or water stains on your ceiling. We’ve repaired chimneys in the Gedney Farms neighborhood where the 1920s brickwork had turned to powder, and we’ve rebuilt crowns in Rosedale homes where the original concrete lasted fifty years before finally cracking through. The point is, we’ve seen your exact problem before, and we know how to fix it so it stays fixed.

Our technicians are background-checked, uniformed, and arrive with professional-grade materials from brands like Gelco and Olympia Chimney. Most repairs are completed in a single visit, and every job is backed by our 90-Day Done Right Promise in writing. No arguing. If it’s not right, we come back and make it right.

We’re not a chain operation sending subcontractors with a clipboard and a sales pitch. We’re a local company founded in 1984, and we plan to be answering the phone in White Plains thirty years from now. That changes how we do business.

What Our Chimney Repair Service Includes

Mortar Repointing

Mortar Repointing is the process of grinding out deteriorated mortar between bricks and packing fresh, matched mortar into the joints. In White Plains, we see this need most often in pre-war homes near the downtown corridor and in the older sections of Fisher Hill, where the original lime mortar has simply weathered away after eighty or ninety years. We color-match our mortar to your existing brickwork and use a proper tuckpointing rig, not a caulk gun, so the repair disappears into the wall. Our repointing jobs carry the 90-Day Done Right Promise, and we photograph every stage so you can see what was removed and what replaced it.

Spalling Brick Repair

Spalling Brick Repair addresses what happens when water trapped inside brick freezes, expands, and blows the face off the brick, leaving a crater that collects even more water. It’s common on White Plains chimneys that lack proper caps or where the crown has cracked, especially on north-facing exposures that never fully dry out. We don’t just slap sealant over spalled brick; we cut out the damaged units, source matching replacement brick when possible, and address the water source that caused the damage in the first place. In a 2019 job on Soundview Avenue, we replaced seventeen spalled bricks and installed a Gelco stainless cap; the chimney has shown no new damage since.

Chimney Waterproofing

Chimney waterproofing is the application of a vapor-permeable sealant that blocks liquid water from entering masonry while allowing trapped moisture to escape. White Plains gets roughly 47 inches of rain and 30 inches of snow annually, and chimneys without waterproofing absorb that moisture like a sponge. We use professional-grade formulas from Copperfield, applied with low-pressure sprayers to avoid driving the product into the flue, and we always repair mortar and brick damage before sealing. A proper waterproofing treatment should last ten years, and we’ll tell you honestly if your chimney is too far gone for sealant alone.

Flashing Repair

Flashing is the sheet metal barrier where your chimney passes through the roof, and it’s the single most common source of chimney-related leaks in White Plains homes. The stepped flashing, counter-flashing, and saddle all work together, and when any piece lifts, rusts, or separates, water runs straight into your attic. We repair flashing with code-compliant techniques, not roofing cement smeared over the problem, and we use materials from Famco and Olympia Chimney that match your roof’s pitch and exposure. Every flashing repair includes a water test before we leave, and we photograph the finished work from both the roof and the attic.

Chimney Rebuilding

Sometimes a chimney is too far gone for spot repairs. When the structure is leaning, the inner wythe has collapsed, or more than a third of the brick faces are spalled, rebuilding is the only safe option. We’ve rebuilt chimneys from the roofline up in White Plains homes on Battle Avenue and Hillside Avenue, always matching original materials and often salvaging usable brick to maintain the home’s character. Rebuilding requires proper scaffolding, weather protection, and a mason who understands how the original chimney was tied to the structure. Our rebuilds include new crowns, proper caps, and flashing integration, and they’re backed by the same 90-Day Done Right Promise as our smaller jobs.

Tuckpointing

Tuckpointing is the decorative and functional technique of cutting narrow grooves in mortar joints and filling them with a contrasting putty to create the illusion of fine, precise brickwork. Many White Plains homes from the 1910s through 1930s were built with this detail, and when the colored putty falls out, the facade looks ragged even if the structure is sound. We match both the base mortar color and the original putty shade, using lime-based formulations appropriate to the era of your home. Tuckpointing is painstaking work; a typical chimney takes two to three days, but the result preserves the architectural detail that makes your house what it is.

Brands We Service for Chimney Repair

We work exclusively with professional-grade materials from industry-trusted manufacturers. For chimney caps and accessories, we specify Gelco stainless steel and copper caps that outlast the galvanized hardware-store versions by decades; we’ve installed hundreds of Gelco units across Westchester and keep their full catalog in stock. For liners and relining systems, we rely on DuraFlex and Olympia Chimney products that carry proper UL listings and are sized with software, not guesswork. Our waterproofing treatments come from Copperfield’s professional line, and our flashing and ventilation components are sourced through Famco. We don’t use builder-grade substitutes, and we don’t substitute without telling you.

Whether your chimney was originally built with Gelco components, needs an Olympia Chimney liner replacement, or uses any other manufacturer’s parts, we can service it correctly. Our trucks carry the tools and materials to complete most repairs in a single visit, and if we need to order a specialty item, we’ll tell you exactly when it will arrive and what the interim safety situation is. No surprises, no placeholder parts.

Signs You Need Chimney Repair Right Now

• White efflorescence on exterior brick - This powdery white deposit is mineral salts left behind when water moves through masonry and evaporates. It means water is getting in, and it’s the earliest warning that mortar joints or the crown are failing. In White Plains, we see this most on chimneys that lack caps or have cracked crowns; left alone, efflorescence precedes spalling by two to five years.
• Water stains on ceiling or walls near the chimney breast - Interior staining means water has already penetrated the exterior masonry, the flashing, or both. The damage you see inside is always less than the damage hidden in the wall cavity. We’ve opened walls in White Plains homes where the framing behind the brick was rotted back to the studs while the interior paint showed only a faint yellowing.
• Crumbling mortar you can pick out with a key - Sound mortar should resist a house key; if you can rake joints loose, the mortar has lost its binder and is no longer protecting the wall structure. This is particularly dangerous in White Plains’ older homes with multi-wythe brick construction, where outer wall failure can compromise the entire chimney.
• Missing or damaged chimney cap - A missing cap invites rain, snow, animals, and debris directly into your flue. Squirrels and raccoons are active year-round in White Plains’ mature neighborhoods, and a capless flue is an open door. Water entering the flue accelerates deterioration of the liner and smoke chamber, turning a $200 cap replacement into a $2,000 liner job.
• Chimney crown cracked or separated from the flue tile - The crown is the concrete slab that tops your chimney, and its job is to shed water away from the flue and onto the roof. Cracks in the crown allow water straight into the chimney’s core, where it destroys the liner, damages the smoke chamber, and rusts the damper. Crown cracks never heal themselves; they only widen.

   Professional repair - Our technicians carry background-checked credentials and arrive with the materials to complete most repairs in a single visit.
