Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Liner & Rebuild Across Old Westbury
Chimney liner installation and rebuild work in Old Westbury typically runs $2,800-$8,500 depending on scope, with most estate properties requiring multiple flue inspections and relining in a single coordinated visit. Our crews are on the road to Old Westbury properties within 24-48 hours of booking, and we complete most liner and rebuild jobs in one day. Call (845) 757-0998 to speak with a live person and schedule your free estimate.
We’ve been working on Old Westbury chimneys for over 42 years. We know the difference between a 1920s Phipps-era masonry stack engineered for coal and a 1960s post-war fireplace converted to gas. That matters because the wrong liner or rebuild approach for your flue type wastes money and creates a genuine safety hazard. Our dispatch and scheduling is coordinated from our New York City office, but our crews serve Old Westbury locally and carry the materials to handle multi-flue estate work without return trips.
Why Hearthstone Chimney Co. Is Old Westbury’s Preferred Chimney Liner & Rebuild Company
Old Westbury homeowners call us back because we document what we find. Every Level-2 camera inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics, just the condition of your flue in pictures and a clear statement of what needs attention now, what can wait, and what doesn’t need anything at all.
Our reputation here is built on estate-scale work. A single Old Westbury service call frequently means inspecting five, eight, or ten flues in one visit. That’s a fundamentally different scope from the single-stack jobs common in neighboring Westbury or New Hyde Park. We’ve learned to schedule, staff, and stock for it.
Response time to Old Westbury is typically next-day or within 48 hours during peak season. We don’t overbook. If we say we’ll be there Thursday morning, we’re there Thursday morning.

Our Chimney Liner & Rebuild Services in Old Westbury
Stainless Steel Liner Installation
Stainless steel liners are the standard for wood-burning and gas conversions in Old Westbury’s pre-1940 masonry. We install DuraFlex and Olympia Chimney stainless systems, sized precisely to each appliance’s BTU output and flue dimension. On estates with multiple wood-burning fireplaces, we often run parallel stainless installations through the same chimney chase, coordinating the work so your formal rooms aren’t torn up for weeks. A typical stainless liner installation in Old Westbury runs $2,800-$4,500 per flue.
Flexible Liner Installation
Flexible liners solve the offset and bend problems common in Old Westbury’s older masonry. Original coal-era chimneys weren’t built straight; they jog around timber framing and masonry piers that a rigid liner simply can’t navigate. Our flexible liner installations, using DuraFlex and Gelco systems, thread through these irregular runs without breaking into walls. This is often the only practical relining method for a 1910 library fireplace with a 45-degree offset three feet above the smoke chamber. Flexible liner work in Old Westbury typically costs $3,200-$5,000 depending on length and access.
Liner Replacement
Clay-tile liner replacement is what we find ourselves doing most often in Old Westbury’s Gold Coast properties. Original terra-cotta flue tiles from 1900-1940 crack, spall, and separate under modern wood-burning heat cycles. The damage is usually hidden until a camera inspection reveals it. We remove the failed liner system and replace it with a modern equivalent appropriate to your fuel type and appliance. Liner replacement in Old Westbury runs $3,500-$6,000 for a standard flue, with multi-flue estate properties scaling proportionally.
Partial Rebuild
Partial rebuilds address the specific failure points we see repeatedly in Old Westbury: spalling fireboxes, deteriorated smoke chambers, and chimney crowns that have lost their structural integrity. The soft historic brick and natural lime mortar used in early 20th-century construction doesn’t tolerate the thermal cycling of modern fires. We rebuild with matching materials where aesthetics matter and modern refractory where performance does. A partial rebuild in Old Westbury typically ranges $4,500-$8,500 depending on height and accessibility.

Trusted Brands We Service in Old Westbury
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney. No builder-grade substitutes. Our trucks stock the common diameters and fittings for Old Westbury’s typical flue sizes, which means most jobs don’t wait on parts. When we encounter an unusual dimension on a custom estate installation, we fabricate or source within 48 hours. HeatShield cerfractory resurfacing is particularly valuable here for smoke chamber parging on historic stacks where full rebuild would destroy original masonry character.
Common Chimney Liner & Rebuild Problems We See in Old Westbury Homes
- Cracked clay-tile flue liners in coal-era masonry. Original terra-cotta tiles engineered for coal-burning temperatures crack and separate under modern wood-burning heat, letting creosote and exhaust reach soft historic brick and lime mortar. We find this in roughly seven of every ten pre-1940 Old Westbury chimneys we inspect.
- Third-degree creosote in seldom-used formal fireplaces. Library and dining room fireplaces that see only occasional winter use never let the flue warm enough for proper draft. Cold northwest winds from October through April compound the problem. The result is glazed, tar-like creosote that standard sweeping won’t remove.
- Chimney swift nesting in off-season flues. Old Westbury’s century-old oak and beech canopy provides ideal habitat, and unused formal fireplaces become nesting sites. Federal protection means active nests cannot legally be removed, forcing scheduling delays for homeowners who wait until fall to call.
- Spalling fireboxes and deteriorated smoke chambers. Soft historic brick and lime mortar deteriorate under repeated thermal cycling. The damage is often concealed behind firebrick facing until a Level-2 inspection reveals the extent.

FAQs - Chimney Liner & Rebuild in Old Westbury
Yes. We schedule and staff specifically for multi-flue estate work, and our Level-2 camera inspection covers every flue in a single coordinated visit. Most Old Westbury properties with five to ten fireplaces take a full day to inspect properly, and we bring enough technicians and equipment so nothing is rushed or skipped. Call (845) 757-0998 to schedule - we’ll quote the package price upfront based on flue count.
Yes, and this is common work for us here. Original unlined stacks from the Phipps era were engineered for coal and never properly adapted for wood or gas conversion. We install DuraFlex or Olympia Chimney stainless liners sized to your appliance, with proper connectors and insulation meeting current NFPA 211 standards. The alternative - continuing to burn in an unlined flue - risks carbon monoxide intrusion and chimney fire.
Only if the nest is inactive and empty. Chimney swifts are federally protected under the Migratory Bird Treaty Act, and active nests with eggs or young cannot legally be disturbed. This is a recurring issue in Old Westbury, where heavy canopy and infrequently used formal fireplaces create ideal nesting conditions. We inspect with a camera to confirm nest status before any cleaning. If active, we schedule for after the young fledge, typically late August. The lesson: inspect early, before nesting season begins.
Not necessarily. Spalling surface damage often responds to HeatShield cerfractory resurfacing or targeted partial rebuild, preserving original masonry where possible. We determine scope with a camera inspection and photo documentation you can see. Full rebuild is reserved for structural failure or when multiple elevations of the stack are compromised. We’ll tell you plainly which category you’re in.
Cold starts produce more creosote than hot, established fires. A rarely used formal fireplace in Old Westbury’s drafty, northwest-exposed chimney never reaches the sustained temperatures that burn off creosote deposits. Weekly use keeps the flue warm and draft strong; occasional use leaves condensed, glazed creosote that accumulates season after season. This is why we recommend annual inspection even for fireplaces you think you hardly use. Call (845) 757-0998 to book yours.
