Why Apex Chimney Cleaning Greater New York Is Hempstead’s Preferred Chimney Repair Company
We’ve worked on chimneys along Merrick Avenue, in the blocks near Barnum Pond, and throughout the ZIP 11550 core where post-war Cape Cods sit shoulder-to-shoulder. That density matters — it means we know how to stage scaffolding in narrow side yards, protect adjacent properties, and work efficiently where parking is tight. Our 1,096 verified customer reviews averaging 4.7 stars include dozens from Hempstead homeowners who found us after another company missed the real problem.
Robert Garcia, our owner, is the lead technician on every job. You won’t get a subcontractor who disappears after the estimate. We’ve been called to Hempstead homes where a previous “repair” addressed cosmetic cracking while the oil-to-gas liner mismatch continued to erode from the inside. That depth of diagnosis comes from 17 consecutive years focused exclusively on chimneys — not gutters, not roofing, not handyman work. From routine sweep to full rebuild, we handle it ourselves.
Our Chimney Repair Services in Hempstead
Mortar Repointing
In Hempstead’s 60- to 80-year-old masonry stock, mortar joints between brick courses are often the first thing to fail. Salt-laden air off Hempstead Bay and South Oyster Bay accelerates the erosion, and freeze-thaw cycles finish what the coastal climate starts. We grind out deteriorated mortar to proper depth and repoint with color-matched, high-alkali-resistant mortar formulated for Nassau County’s exposure conditions. A typical repointing job on a Hempstead chimney runs $350–$950 depending on accessibility and the number of courses affected.
Spalling Brick Repair
Spalling — the flaking and crumbling of brick faces — is epidemic on Hempstead chimneys above the roofline. The combination of salt air, wind-driven rain from nor’easters, and decades without waterproofing leaves brick saturated and vulnerable. We remove spalled units, source matching replacement brick where possible, and rebuild the affected courses with proper bonding. In the Great Oaks at Merrick area, we’ve replaced entire chimney shoulders where spalling had compromised structural integrity. Spalling repair in Hempstead typically ranges from $800 for localized work to $2,200 for extensive surface rebuilding.
Chimney Waterproofing
Hempstead’s coastal position — roughly 7–10 miles inland but fully exposed to Atlantic weather systems — makes waterproofing essential, not optional. We apply vapor-permeable sealers that let masonry breathe while blocking liquid water intrusion. This is particularly critical on homes near The Changing Water Levels of Hempstead Lake, where groundwater and atmospheric moisture create a double load on foundation-adjacent chimney bases. Waterproofing a standard Hempstead chimney runs $400–$750 and extends serviceable life by years.
Flashing Repair
Step flashing and counterflashing where the chimney meets the roof are common leak points in Hempstead’s older housing. Nor’easter winds drive rain directly into deteriorated cap joints, and once water finds a path, it follows the chimney cavity down through interior walls. We fabricate and install custom flashing using professional-grade materials, integrating with your existing roofing without the disruption of a full chimney rebuild. Flashing repair in Hempstead typically costs $450–$1,100.
Chimney Rebuilding
When deterioration exceeds the point of repair, we rebuild. Hempstead’s oil-to-gas conversion history adds complexity — many chimneys that need rebuilding also need relining to handle modern appliance exhaust. Robert Garcia assesses each case personally, determining whether partial rebuilding (from the roofline up) or full reconstruction is warranted. Partial rebuilds in Hempstead run $2,800–$4,500; full rebuilds with new liner installation range $5,500–$9,000 depending on height, access, and liner specification.
Tuckpointing
Tuckpointing is the precise removal and replacement of failed mortar joints without disturbing surrounding brick. In Hempstead’s dense neighborhoods, where chimneys often serve as shared property-line features between attached or semi-attached homes, this surgical approach minimizes disruption. We match existing mortar color and profile, preserving the architectural character that defines these post-war blocks. Tuckpointing costs align with repointing ranges but may run higher where access is constrained.

Trusted Brands We Service in Hempstead
We install and work with professional-grade materials from Gelco, Olympia Chimney, and Copperfield — the same product lines specified by commercial contractors across Long Island. For Hempstead customers, this means we don’t wait on special orders from out of state. When we find a failed cap, damaged crown, or compromised liner during inspection, we can often source the correct replacement from our regular inventory and return to complete the job without extended delay. Gelco caps and Copperfield flashing components are particularly suited to Hempstead’s salt-air environment, with finishes rated for coastal exposure.
Common Chimney Repair Problems We See in Hempstead Homes
- Oil-to-gas liner mismatch destroying clay flue tiles from within. In the Mott Section and North Merrick Acres, clay-tile flue liners originally sized for No. 2 fuel oil are now venting mid-efficiency gas furnaces. The oversized flue causes condensation of acidic combustion byproducts that erode the liner from the inside out — a failure invisible from the roofline but hazardous at the smoke shelf and firebox.
- Salt-air spalling on exposed chimney crowns and upper brick courses. Hempstead’s position between Hempstead Bay and South Oyster Bay exposes masonry to salt-laden coastal air that accelerates surface breakdown faster than in inland Nassau or Queens. We see advanced spalling on chimneys that would be merely weathered in less exposed locations.
- Nor’easter-driven rain intrusion through deteriorated cap joints. Wind-driven rain off the Atlantic funnels directly into Hempstead’s chimney cap joints, especially on homes without overhanging roof protection. Once moisture penetrates, freeze-thaw cycling during winter months progressively destroys mortar and brick.
- Never-inspected chimneys in 60- to 80-year-old housing stock. The core of ZIP 11550 contains thousands of original masonry chimneys that have never had professional lining assessment despite fuel-source conversions. Homeowners assume visible brick means sound construction — it doesn’t.

What moves a job toward the higher end? Height and access are the big variables — a two-story Colonial with a steep roof in Briar-Cliff Park at Merrick takes more labor than a single-story ranch with walkable pitch. The extent of hidden damage also matters; we won’t know the full condition of your flue liner until we’ve camera-inspected it. We provide upfront, itemized estimates before any work begins, and estimates are always free. Call (866) 884-9512 to schedule with Robert Garcia.

FAQs — Chimney Repair in Hempstead
Your chimney’s original clay flue liner was sized for the hot, buoyant exhaust of a No. 2 fuel oil burner. Modern gas furnaces produce cooler, wetter exhaust that condenses inside an oversized flue, creating acidic moisture that erodes the clay from the inside out. This failure is invisible from outside but can cause dangerous flue gas leakage into your home. On a 1950s Colonial in North Merrick Acres, our crew found a clay-tile liner originally for oil that had softened and flaked from acidic gas condensation — we relined with a DuraFlex stainless steel system, restoring safe draft and meeting current code. If your Hempstead home was converted from oil to gas without a liner inspection, call (866) 884-9512 for a camera evaluation; estimates are free.
Hempstead’s exposure to salt-laden air from Hempstead Bay and South Oyster Bay accelerates masonry deterioration by 30–50% compared to inland locations. Salt crystals penetrate brick and mortar, expanding with moisture cycles and causing surface spalling, efflorescence, and joint erosion. We specify materials and sealants rated for coastal exposure, and we recommend more frequent inspection intervals than for inland properties. Call (866) 884-9512 to schedule — we know what to look for in Hempstead’s environment.
Yes, though these properties typically use direct-vent or prefab fireplace systems rather than traditional masonry, so our inspection and repair protocols differ. We assess factory-built chimney assemblies, chase covers, and termination caps using manufacturer-specific guidelines rather than the masonry-focused approach needed for Hempstead’s post-war core. If you’re in the redevelopment zone and experiencing drafting issues or exterior deterioration, call (866) 884-9512 — Robert Garcia will determine whether you need chimney-specific work or HVAC crossover service.
Tuckpointing is the targeted removal and replacement of deteriorated mortar joints while preserving surrounding brick. Your Hempstead chimney needs it when you can probe mortar joints with a screwdriver and extract loose material, or when you notice hairline cracking that has widened into gaps. In Hempstead’s 60- to 80-year-old housing stock, we often find original lime-based mortar that has simply reached the end of its service life. Tuckpointing costs $350–$950 in Hempstead depending on the number of courses and access difficulty. Call (866) 884-9512 for an exact quote — estimates are free.
Yes — flashing repair is one of our most common calls in Hempstead, and it rarely requires chimney rebuilding. We remove the compromised step flashing and counterflashing, inspect the underlying roof deck and chimney masonry for hidden damage, then install new custom-fabricated flashing integrated with your existing roofing. Most Hempstead flashing repairs are completed in a single day for $450–$1,100. Call (866) 884-9512 to stop the leak before winter — estimates are free.
