We’re Apex Chimney Cleaning Greater New York, and Robert Garcia — our owner — handles every DuraFlex job personally. Seventeen years of chimney-only work, more than a thousand documented outcomes, and a straightforward approach: we tell you what we find, what it means, and what we’d do in our own home.
Why Larchmont Residents Choose Us for DuraFlex Service
Robert Garcia grew up in the Bronx, not far from Yankee Stadium, and spent his apprenticeship under a veteran sweep who drilled one lesson into him: a clean flue isn’t a luxury — it’s what keeps a family safe through a New York winter. That was 17 years ago. Since then, he’s cleaned, inspected, and repaired chimneys across the five boroughs and surrounding counties, including hundreds of DuraFlex installations and service calls right here in Larchmont.
We are not authorized by DuraFlex. We’re independent. That matters because it means Robert can recommend the liner alloy that actually fits your home’s conditions, not just the catalog default. For Larchmont’s salt-laden coastal air, that often means steering homeowners toward 904L alloy over standard 316Ti — a call a manufacturer-affiliated tech might not make.
Our customers know who shows up. Robert runs every job himself or alongside his small crew. When something looks off — pitting on a windward-facing stack, condensate pooling in an oversized coal-era flue — he’s the one on the roof making the call. No dispatchers. No rotating subcontractors. The same person who quotes the work does the work.
That accountability shows in the numbers: 1,096 verified reviews averaging 4.7 stars. Not a lucky streak — consistency over 17 years.
Common DuraFlex Chimney Cleaning Problems We Solve in Larchmont
- External pitting on 316Ti liners from salt spray. Larchmont’s position on Long Island Sound means wind-driven salt air hits windward-facing chimneys year-round. We’ve replaced 316Ti liners in the Manor neighborhood that showed pitting corrosion in eight years — half their expected lifespan inland. A cleaning inspection catches this before the liner fails structurally.
- Acidic condensate degradation in oversized coal-era flues. Many Larchmont homes built between 1890 and 1940 were never properly downsized during oil or gas conversions. The resulting oversized flue creates slow draft and allows acidic condensate to pool against DuraFlex liners. We identify this pattern during Level 2 inspection and resize or recommend 904L alloy when appropriate.
- Premature top plate corrosion from crown cracks. Freeze-thaw cycles compounded by salt deposition crack chimney crowns faster here than in Scarsdale or White Plains. Water infiltration reaches DuraFlex top plates and hardware. Our cleaning visits include crown assessment — we catch it before the liner connection fails.
- Creosote buildup from poor draft in converted systems. Oversized flues don’t just trap moisture; they burn inefficiently, leaving more creosote on liner walls. Larchmont’s pre-WWII homes with multiple fireplaces are especially prone. Rotary cleaning removes it; inspection determines if the flue geometry is the root cause.
- Failed seals at liner joints from thermal cycling. Coastal temperature swings — cold Sound air against heated flue gases — stress DuraFlex joint seals more aggressively than stable inland conditions. We inspect every joint during cleaning and reseal with high-temp rated compounds rated for marine-exposure environments.
DuraFlex Service in Larchmont: What Local Conditions Mean for Your Equipment
Larchmont’s pre-WWII homes along the Manor waterfront were built with coal-era flue dimensions that were never downsized during oil or gas conversions, creating oversized flues that trap acidic condensate — a pattern our crews encounter almost exclusively in this neighborhood. The grand Tudors and Colonials on Shore Road and the surrounding Larchmont Manor area were designed for coal heat: wide, rectangular flues that drafted hard and hot. When homeowners switched to oil or gas in the 1950s and 60s, many installers simply ran a smaller pipe through the existing space without proper relining. The result? A DuraFlex liner swimming in excess volume, with gases that cool too fast, condense on the liner walls, and turn into sulfuric acid that eats from the inside out.
We recently cleaned a DuraFlex liner at a Tudor Revival home on Shore Road in the Larchmont Manor area. The 316Ti liner, installed 12 years ago during a gas conversion, showed external pitting from salt spray. We recommended a protective crown coating and switched to a 904L alloy cap to extend its life. The homeowner didn’t know the coastal exposure was accelerating the damage until Robert pointed out the pattern — it’s not visible from the ground, and it doesn’t announce itself with smoke or smell. It just gets worse until it fails.
That’s why we emphasize Level 2 inspection with every DuraFlex cleaning in Larchmont. Camera inspection reveals what a brush-and-mirror sweep cannot: condensate pooling at offsets, joint separation, and the early-stage corrosion that salt air produces.
DuraFlex Models & Products We Service in Larchmont
We work with the full DuraFlex residential line: 316Ti round liners, 316Ti oval liners for rectangular flue conversions, and 904L alloy liners for high-corrosion environments. For Larchmont’s coastal conditions, we stock 904L alloy components locally for faster turnaround when replacement is the right call.
Our parts approach is straightforward. We use genuine DuraFlex liners for installations — the same lines commercial contractors specify — but we’re not locked to factory defaults. When a liner can be salvaged, we patch and seal rather than replace. Robert carries HeatShield and Gelco crown repair materials on his truck, plus Famco and Copperfield termination hardware, so most Larchmont jobs don’t wait on shipping.
OEM-compatible, not OEM-captive. That’s the difference independence makes.

FAQs — DuraFlex Chimney Cleaning in Larchmont
Salt-laden air off Long Island Sound accelerates pitting corrosion on standard 316Ti DuraFlex liners, especially on windward-facing stacks. Scarsdale’s inland location doesn’t expose liners to the same marine atmospheric corrosion. We inspect for this pattern specifically during Larchmont cleanings and often recommend 904L alloy for replacement. Call (866) 884-9512 for an exact assessment — estimates are free.
Yes, and it often should. Many 1920s Larchmont homes have coal-era flue dimensions that are oversized for modern gas or oil appliances. A properly sized DuraFlex 316Ti or 904L liner improves draft, reduces creosote buildup, and prevents acidic condensate from pooling against clay tile. Robert measures the flue and appliance output to specify the right diameter — never a one-size-fits-all approach.
Most liner replacements in Larchmont require a permit from the Village of Larchmont Building Department. We handle permit application as part of our installation service and coordinate inspection scheduling. For cleaning and inspection alone, no permit is typically required. We’ll clarify your specific situation during the free estimate visit.
Standard rotary poly or wire brushes work for normal creosote, but salt residue and light surface corrosion on coastal-exposed 316Ti liners benefit from modified technique — lower RPM, specific brush selection to avoid scoring the alloy surface. Robert adjusts approach based on what the camera inspection shows. Routine cleaning prevents the buildup that makes aggressive methods necessary.
The active gas flue needs a properly sized DuraFlex liner for safety and efficiency. The abandoned oil flue should be sealed at top and bottom to prevent water infiltration and drafting issues — we often cap with Famco or Copperfield hardware and seal with HeatShield crown coating. Two liners are rarely needed; one correct installation plus proper abandonment of the second flue is the standard approach in Larchmont’s multi-flue pre-WWII homes. Call (866) 884-9512 and Robert will assess your specific configuration.
