Robert Garcia, our owner and lead technician, handles every job personally, so when you call (866) 884-9512, you’re talking to the person who’ll be on your roof, not a dispatcher sending an anonymous crew. Our Chimney Repair team knows the 11565 ZIP code’s specific problems: salt-corroded flashing, Portland cement repointing failures, and undersized flues from the village’s 1920s–1950s housing stock. We’re usually on-site in Malverne within 24–48 hours of your call.
Why Apex Chimney Cleaning Greater New York Is Malverne’s Preferred Chimney Repair Company
We’ve earned our reputation in Malverne through 17 years of chimney-only work and 1,096 verified customer reviews averaging 4.7 stars. Homeowners here aren’t looking for a handyman who “also does chimneys” — they want a specialist who understands why their 1940s Cape Cod chimney fails differently than a 1990s build in West Hempstead.
Robert handles every Malverne job himself. That means when we inspect your chimney on Norwood Avenue or repair spalling brick near Lakeview Avenue, the owner is the one climbing the ladder, running the camera, and explaining what he found. No subcontractors. No rotating crews who can’t remember your flue configuration from last season.
Our response time to Malverne averages same-day or next-day for standard repairs, and we carry professional-grade materials from Gelco, Olympia Chimney, and Famco on our truck — the same lines commercial contractors use. That stock means most Malverne homeowners don’t wait a week for parts while water keeps seeping through cracked crowns.
We know the local inspection landscape too. Malverne’s building department enforces Nassau County’s chimney safety codes, and we’ve worked with enough local real estate transactions to know what triggers a failed inspection during a home sale. If you’re buying or selling in 11565, we’ll document the condition properly.
Our Chimney Repair Services in Malverne
Mortar Repointing
Malverne’s original single-wythe brick chimneys were built with soft lime mortar that flexes with temperature swings. The problem we see constantly — especially on Hempstead Avenue and the older blocks near the village center — is that previous owners or inexperienced masons repointed with Portland cement. It’s too rigid. It cracks. It falls inward. We recently repaired a 1936 Tudor on Hempstead Avenue where the original oil-furnace flue had been repointed with Portland cement decades ago. That rigid mortar had crumbled inward, blocking the flue and masking a cracked clay liner. We installed a DuraFlex stainless steel liner after a camera inspection revealed the damage. Our repointing uses mortar matched to the original compressive strength, so your chimney breathes properly through another century of Malverne winters.
Spalling Brick Repair
Spalling — those flaking, crumbling brick faces — is epidemic in Malverne’s pre-1960 housing stock. The freeze-thaw cycle saturates porous brick, especially on south-facing exposures that take the brunt of nor’easter-driven rain. We’ve replaced spalled courses on chimneys from Norwood Avenue to the Lakeview border, always sourcing brick that matches the original color and texture. Left untreated, spalling exposes the inner wythe to accelerated deterioration, and in a single-flue chimney, that compromises structural integrity fast.
Chimney Waterproofing
Malverne’s position on Long Island’s South Shore, roughly 3–4 miles from the Atlantic and Great South Bay, means salt-laden air accelerates mortar joint erosion and metal flashing corrosion faster than inland Nassau County towns. Nor’easters and tropical remnants hitting south-facing rooflines drive rain directly into chimney crowns. We apply vapor-permeable waterproofing agents — never film-forming sealers that trap moisture — specifically formulated for masonry exposed to marine environments. For Malverne chimneys, waterproofing isn’t an upsell; it’s survival. We typically recommend reapplication every 5–7 years, sooner if your crown shows hairline cracking.
Flashing Repair
Flashing failure is the most common leak source we diagnose in 11565. The salt air corrodes galvanized step flashing and counterflashing within 5–7 years, far faster than the 15–20 year lifespan you’d expect in Plainview or Syosset. We fabricate custom flashing from copper or lead-coated copper — materials that laugh at salt spray — and we integrate it properly with your roofing system. Temporary caulk jobs fail; we see the evidence every spring when Malverne homeowners call with new ceiling stains.

Trusted Brands We Service in Malverne
We install professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield — the same product lines specified by commercial masonry contractors across Nassau County. For Malverne customers, that means no waiting on special orders for standard repairs. Our truck stocks DuraFlex stainless liners for the relining work that’s standard in this village’s converted chimneys, Gelco caps and guards sized for the smaller flue openings common in 1920s–1950s construction, and Olympia Chimney’s waterproofing compounds formulated for coastal exposure. When we inspect your chimney on Norwood Avenue or near the LIRR tracks, we can often complete the repair same-day because the right parts are already on-site.
Common Chimney Repair Problems We See in Malverne Homes
- Salt-corroded flashing and caps. Malverne’s coastal proximity means metal components deteriorate years faster than inland. We replace failed galvanized flashing with copper or stainless systems that withstand marine air.
- Portland cement repointing failures. Hard mortar from previous repairs cracks and drops into the flue, creating blockages and false confidence that the chimney is “recently repaired.” We remove it and repoint with appropriate lime-based mortar.
- Undersized or unlined flues in converted systems. Original coal or oil flues — often 6″ x 6″ or smaller — can’t handle modern gas inserts or wood stoves safely. Inadequate draft, condensation damage, and carbon monoxide risk follow. Relining is the fix.
- Crown cracks from wind-driven rain. Malverne’s south-facing rooflines take direct hits from nor’easters. Cracked crowns let water saturate the chimney top, accelerating freeze-thaw damage throughout the structure.

Here’s what Malverne homeowners typically invest in chimney repair, based on 17 years of jobs in 11565 and surrounding Nassau County villages:
| Service | Typical Range in Malverne |
|---|---|

Malverne’s older housing stock and coastal exposure push some costs toward the higher end of these ranges — salt damage means more extensive metal replacement, and original clay liner failures often require full relining rather than spot repair. We provide exact, written estimates after camera inspection, never ballpark figures over the phone. Estimates are free. Call (866) 884-9512 to schedule.

FAQs — Chimney Repair in Malverne
Portland cement is too hard and rigid for Malverne’s original soft brick, which expands and contracts with temperature changes. The cement cracks, separates from the brick, and falls into the flue — we’ve pulled pounds of it from chimneys on Hempstead Avenue and Norwood Avenue. We repoint with lime-based mortar matched to your chimney’s original flexibility. Call (866) 884-9512 for a free inspection if you suspect hard mortar was used on your stack.
Salt-laden air from the Atlantic, roughly 3–4 miles south, accelerates corrosion of metal flashing, caps, and damper components by 30–50% compared to inland Nassau County. We see galvanized flashing fail in 5–7 years here versus 15–20 years in Syosset. We specify copper, stainless steel, or powder-coated components for Malverne installations. If your cap or flashing is more than five years old, schedule an inspection — corrosion may be advanced.
Usually not without modification. Original oil flues in 1940s Malverne construction are typically 6″ x 6″ or smaller — inadequate for modern gas inserts, which require proper draft and clearance to combustibles. We camera-inspect to verify flue condition, then typically install a DuraFlex stainless steel liner sized for your new appliance. Never assume an old flue is compatible; we’ve found cracked clay, missing tiles, and even blockages from fallen mortar. Call (866) 884-9512 to assess your specific chimney.
Flashing replacement and crown repair, followed closely by flue relining. The combination of salt corrosion and wind-driven rain from nor’easters means flashing fails early, and crown cracks let water penetrate the chimney core. For the village’s converted heating systems, relining is nearly standard — original clay liners in 1920s–1950s chimneys weren’t designed for modern appliances. Most Malverne jobs involve at least two of these issues simultaneously.
A sweep removes combustible deposits; a reline addresses structural flue damage or sizing problems. If your chimney inspection reveals cracked or missing clay tiles, gaps between flue sections, or an undersized flue for your current appliance, sweeping alone is insufficient and potentially dangerous. We run a camera inspection on every Malverne chimney we service — you’ll see the footage yourself. Call (866) 884-9512 to book; estimates and camera inspections are free.
