Call (845) 757-0998

We’ve worked on chimneys from the post-war ranches near Broadway Mall to the larger colonials up toward Jericho Turnpike. Hicksville’s freeze-thaw cycles hit hard from December through March, and the sandy loam soil shifts more than homeowners expect. That combination cracks mortar, loosens flashing, and turns small leaks into spalling brick. We’ve seen it on Duffy Avenue, on the older streets off Old Country Road, and in every neighborhood between. Russell Haines has led this company since 1984, and our technicians are background-checked, uniformed, and trained to document every repair with photos you can see and a plain-English verdict you can understand.

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 Hicksville, we repoint chimneys where winter moisture has penetrated the joints, frozen, and expanded - you’ll see crumbling or missing mortar, sometimes gaps wide enough to slide a coin into. We analyze the original mortar composition to match color and hardness, then repoint by hand so the repair blends with the existing chimney face. Most repointing jobs on a standard Hicksville chimney run one to two days, and we protect the work area with drop cloths and scaffolding as needed.

Spalling Brick Repair

Spalling occurs when water trapped inside bricks freezes and pushes the face of the brick off in flakes or chunks. Hicksville’s coastal-influenced climate brings heavy spring rains followed by hard freezes, which accelerates spalling on chimneys without proper caps or waterproofing. We remove spalled bricks, source matching replacements from regional suppliers familiar with Long Island’s common brick profiles, and rebuild the affected courses with proper bonding patterns. For extensive spalling, we may recommend partial rebuilding rather than patchwork that will fail again in two seasons.

Chimney Waterproofing

Chimney waterproofing applies a vapor-permeable sealant that blocks liquid water while allowing moisture vapor to escape. Hicksville’s nor’easters and summer humidity mean chimneys here stay wet longer than inland areas, so waterproofing is preventive maintenance that extends repointing and brick repairs by years. We clean the chimney surface with a masonry-safe detergent, repair any open joints first, then apply two coats of professional-grade waterproofing agent by brush and sprayer. We use products formulated for freeze-thaw resistance, not the hardware-store versions that trap moisture and accelerate damage.

Flashing Repair

Flashing is the metal barrier where your chimney passes through the roof, and it’s the single most common leak point we find in Hicksville inspections. The expansion and contraction of our temperature swings work flashing loose, and the sandy soil that shifts beneath Hicksville homes can stress the chimney-to-roof joint over time. We remove damaged flashing, inspect the underlying deck for rot, and install new step flashing and counterflashing using proper integration with your shingles or flat-roof membrane. We seal with high-temperature sealants rated for chimney applications, not generic caulk that hardens and cracks.

Chimney Rebuilding

When structural damage, extensive spalling, or leaning exceeds what spot repairs can safely address, we rebuild. In Hicksville, we’ve rebuilt chimneys damaged by long-neglected leaks, lightning strikes, and vehicle impacts on low exterior chimneys. We dismantle only what’s necessary, salvage usable brick when possible, and rebuild to current Nassau County code with proper flue lining, crown slope, and cap installation. Russell Haines personally reviews every rebuild estimate to ensure we’re not rebuilding what could be repaired, and not repairing what will fail within the warranty period.

Tuckpointing

Tuckpointing is a specialized cosmetic and protective technique where we cut narrow grooves into the mortar joints and fill them with contrasting mortar to create the appearance of fine, uniform joints. On Hicksville’s older homes, particularly the pre-war and immediate post-war stock near the train station, tuckpointing restores the crisp visual lines that have softened over decades of weathering. We match the original joint profile - struck, weathered, or flush - and use lime-based mortars on historic chimneys where Portland cement would cause accelerated deterioration. The result is a chimney that looks correct for its era and is protected for the next generation.

Brands We Service for Chimney Repair

We work exclusively with professional-grade materials from manufacturers who stand behind their products the way we stand behind ours. For chimney liners and relining components, we specify DuraFlex and Olympia Chimney products - we’ve installed hundreds of their stainless steel and aluminum liners in Hicksville and Nassau County homes, and we stock common diameters and adapters to complete most liner repairs without ordering delays. For crown and cap applications, Gelco and Copperfield provide the galvanized and stainless steel components we trust to shed water and withstand our coastal air without rust-through in five years.

On waterproofing and restoration mortar jobs, we use HeatShield refractory products and Famco ventilation accessories where flue performance or exterior termination details require specific engineering. We’ve serviced and repaired chimneys with these brands and many others over four decades, and our technicians carry the catalogs and technical contacts to source OEM-compatible parts for systems we didn’t originally install. Whether your chimney was built with these brands or any other make, we can assess it honestly, repair it correctly, and document what we did.

Signs You Need Chimney Repair Right Now

• White staining (efflorescence) on the exterior brick. This powdery white deposit means water is moving through your masonry, dissolving salts, and depositing them on the surface. In Hicksville, we see this most on north-facing chimneys that stay damp through our cloudy winter months. It’s not just cosmetic - it’s evidence of internal saturation that precedes spalling and structural freeze damage.
• Chunks of brick or mortar in your yard or on the roof. When pieces fall off, the freeze-thaw cycle has already destroyed the bond. We’ve picked up spalled brick fragments from Hicksville driveways after every hard winter, and each one represents a chimney face that will keep deteriorating until the water path is interrupted.
• Rust stains on the chimney face or at the cleanout door. Rust indicates that metal components - the damper, firebox, or liner - are corroding from moisture exposure. In our coastal climate, rust accelerates faster than inland, and a rusted damper can fail to open fully, sending smoke and carbon monoxide into your living space.
• Water on the firebox floor after rain. This is a direct leak, usually through failed flashing, a cracked crown, or deteriorated mortar joints. Hicksville’s wind-driven rains exploit every opening, and water in the firebox damages the firebrick and can wick into adjacent framing if ignored through multiple seasons.
• Visible leaning or separation from the house. A chimney that tilts or pulls away from the wall has compromised footing support or corroded lateral support straps. The sandy soils in parts of Hicksville settle unevenly, and we’ve stabilized leaning chimneys with proper underpinning and structural reconnection before they became a collapse hazard.

Our Chimney Repair Process - Step by Step

1. 1
   Schedule and confirm. Call (845) 757-0998 and a live person will answer, 24 hours a day. We’ll ask about your chimney’s age, symptoms you’ve noticed, and your availability. We don’t use callback queues or scheduling apps - we confirm a specific arrival window and call if traffic on the LIE or Northern State shifts our timing.
2. 2
   Level-2 camera inspection and documentation. Our technician arrives in a marked vehicle, uniformed, and begins with a visual exterior assessment and an internal video scan using a chimney camera. You receive photos of damage, measurements of flue dimensions, and a plain-English verdict on what’s wrong, what can wait, and what needs attention before the next burning season.
3. 3
   Upfront estimate with line-item pricing. We present repair options with exact costs - not ranges that balloon on the invoice. Our no-hassle upfront pricing means the number on the estimate is the number on the bill. For repairs over $250, we offer $50 off, and we always provide free second opinions on any written estimate you’ve received from another company.
4. 4
   Professional repair with documented materials. We complete most chimney repairs in a single visit, using the professional-grade brands we specified in your estimate. Our technicians work with drop cloths, ladder stabilizers, and proper scaffolding. Russell Haines requires photo documentation of before, during, and after conditions for every repair we perform.
5. 5
   Written warranty and follow-up. Every repair is covered by our 90-Day Done Right Promise - in writing, no arguing. If something isn’t right, we come back. We also note any maintenance that will extend the repair’s life, such as waterproofing scheduling or cap inspection intervals, and we file your inspection video for reference on future visits.
