We’ve rebuilt chimneys from Chimney Liner & Rebuild - Whitestone‘s waterfront homes to the pre-war brick stacks in downtown Flushing, and we’ve learned what this borough’s freeze-thaw cycles do to masonry. Flushing’s older housing stock, much of it built before modern liner codes, often has unlined brick chimneys or clay liners that have cracked after decades of heating and cooling. When a liner fails, exhaust gases can leak into living spaces. When mortar joints crumble, the whole structure becomes a fire risk. We document every defect with photos you can see, explain the repair in plain English, and give you a written estimate before any work starts. Our 90-Day Done Right Promise means if it’s not right, we come back. No arguing, no paperwork chase.

What Our Chimney Liner & Rebuild Service Includes

Stainless Steel Liner

A stainless steel liner is a continuous metal tube we install inside your existing chimney flue to carry exhaust gases safely to the outside. In Flushing, we recommend stainless steel for oil and gas systems especially, because it withstands the corrosive condensation that forms when modern high-efficiency appliances run in old, oversized flues. We size every liner to the appliance using NFPA 211 standards, and we source our stainless steel from Olympia Chimney and DuraFlex, brands we’ve worked with for decades. A properly sized stainless liner stops the acidic moisture that destroys brick from the inside out.

Flexible Liner

Flexible liners are corrugated stainless steel tubes that navigate offsets and bends in chimney flues where a rigid pipe won’t fit. Many Flushing homes, particularly the attached row houses near Roosevelt Avenue and the older detached homes south of Northern Boulevard, have chimney flues with offsets built to dodge floor joists or previous renovations. We measure the flue with a video camera first, then select the right diameter and length of DuraFlex or Gelco flexible liner for the job. The installation requires pulling the liner from the top with controlled tension, a technique our technicians have refined over hundreds of Queens installations.

Liner Replacement

Liner replacement becomes necessary when an existing clay tile liner has cracked, shifted, or deteriorated to the point that gaps allow combustion gases into the chimney walls. In Flushing, we see this most often in homes built between 1920 and 1960 where the original terracotta tiles have succumbed to thermal shock, especially after chimney fires that homeowners may not have even noticed. We remove the damaged tiles when accessible, or we install a new stainless steel liner inside the compromised flue if demolition would damage surrounding masonry. Every replacement includes a smoke test and camera verification before we sign off.

Partial Rebuild

A partial rebuild addresses specific sections of chimney failure without the cost of tearing down the entire structure. The most common partial rebuild in Flushing is the top six to eight courses above the roofline, where freeze-thaw damage concentrates, or the chimney crown that caps the flue tiles. We’ve rebuilt crowns and upper courses on homes from Chimney Liner & Rebuild - College Point to Elmhurst using matching brick and proper weatherproofing. A partial rebuild makes sense when the lower chimney is sound but the exposed upper section has spalled, cracked, or lost mortar joints. We always inspect the interior flue during a partial rebuild to ensure the liner is still intact.

Full Chimney Rebuild

A full chimney rebuild is required when structural damage extends through multiple elevations, when the chimney has separated from the house wall, or when previous repairs have compromised the original design. In Flushing’s flood-prone areas near Flushing Creek and the older homes with sand-based mortar, we’ve seen chimneys that have leaned, settled, or completely lost their structural integrity. We dismantle the chimney course by course, salvage reusable brick when possible, and rebuild to current code with proper footings, flue sizing, and weatherproofing. A full rebuild includes a new liner system sized for your heating appliance, and we coordinate all permits with the NYC Department of Buildings.

Liner Repair

Liner repair is a targeted fix for localized damage that doesn’t warrant full replacement. We use HeatShield cerfractory sealant, a refractory compound that fills cracks and gaps in clay tile liners, restoring the flue’s integrity without removing the existing tiles. This works when the tile system is largely intact but has minor cracking, mortar joint erosion, or small gaps at tile joints. We video-scan the flue first to map every defect, then apply the sealant with specialized tools that smooth it to a continuous surface. HeatShield carries a limited lifetime warranty when applied by certified technicians, and we’ve used it successfully in dozens of Flushing homes where full replacement would have been excessive.

Brands We Service for Chimney Liner & Rebuild

We work exclusively with professional-grade materials from manufacturers who stand behind their products the way we stand behind ours. DuraFlex flexible liners have been our go-to for offset flues in Queens for over fifteen years; their corrugated 316Ti stainless steel holds up to the acidic condensate from modern gas appliances, and we keep common diameters in stock to avoid delays. HeatShield’s cerfractory resurfacing system lets us repair rather than replace clay tile liners when the damage is limited, and we’ve completed their factory certification program to ensure every application meets warranty standards. Olympia Chimney’s rigid stainless steel liners and components give us precise, engineered solutions for straight flues where maximum draft efficiency matters.

We also install Gelco chimney caps and screening, and we source specialty fittings from Famco and Copperfield when a job requires custom fabrication. Whether your existing system is DuraFlex, HeatShield, Olympia Chimney, or any other make, we can inspect it, repair it, or replace it with the right component for your setup. We don’t use builder-grade substitutes, and we don’t install parts we wouldn’t put in our own homes.

Signs You Need Chimney Liner & Rebuild Right Now

• White staining or efflorescence on exterior brick. That chalky white deposit is minerals left behind when water moves through the masonry and evaporates. In Flushing, where winter temperatures swing above and below freezing repeatedly, water trapped in porous brick expands and contracts until the face of the brick spalls off. Efflorescence means water is getting in, and if it’s getting through the brick, exhaust gases may be getting out through the same path.
• Flaking or spalling brick surfaces. When the hard outer face of a brick pops off, exposing the softer core beneath, the chimney’s structural integrity is compromised. We see this most on south- and west-facing chimneys in Flushing that take the brunt of sun-driven freeze-thaw cycles. Spalling accelerates quickly; a few damaged bricks this winter can become a hundred next winter if water continues to penetrate.
• Rust stains on the chimney crown or down the face. Rust means metal is corroding somewhere inside the flue, usually a deteriorated liner or a missing cap that let water reach the damper or connector pipe. In homes with original clay liners, rust often signals that flue gases have been condensing in the chimney because the liner is too large for the appliance, a common mismatch in Flushing’s older housing stock.
• Smoke or odors inside the house when the heating system runs. This is not a nuisance to tolerate. Smoke infiltration means combustion products, including carbon monoxide, are finding paths through cracks in the liner or gaps in the masonry. We treat every smoke odor complaint as a potential safety issue and schedule a Level-2 inspection within 24 hours.
• Visible cracks or gaps in the chimney crown. The concrete or mortar crown at the top of your chimney is the first line of defense against water. When it cracks, water pours directly into the flue and the space between the flue liner and the brick wall. In Flushing’s climate, a cracked crown can destroy a liner in two to three winters. Crown repair or replacement is straightforward preventive work that avoids catastrophic damage.

Our Chimney Liner & Rebuild Process - Step by Step

1. 1
   Schedule and confirm. When you call (516) 206-6672, a live person answers, 24 hours a day. We book a two-hour arrival window that works with your schedule, and we call 30 minutes before our technician is en route. You’ll know who’s coming; our technicians are background-checked, uniformed, and arrive in marked vehicles.
2. 2
   Level-2 camera inspection. Before we recommend any work, we video-scan the entire flue interior with a high-resolution camera on a flexible rod. You watch the feed in real time, and we save the recording. We document cracks, gaps, creosote buildup, and structural anomalies with photos you can see. This inspection is the foundation of every estimate we provide; we don’t guess, and we don’t sell repairs for problems we can’t demonstrate.
3. 3
   Plain-English verdict and written estimate. Our technician explains what the camera revealed, what it means for your safety and your heating system’s performance, and what options you have. For liner work, we’ll specify the diameter, material, and brand we recommend and why. For rebuilds, we’ll show you the exact courses or sections that need attention. The estimate is itemized, with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
4. 4
   Professional installation or rebuild. Most liner installations and partial rebuilds are completed in a single visit. We arrive with the materials specified in your estimate, protect your floors and furnishings, and work efficiently without cutting corners. For full rebuilds, we may need two to three days depending on weather and permit inspections. We coordinate all NYC Department of Buildings filings for structural work.
5. 5
   Final inspection, documentation, and guarantee. Every job ends with a follow-up camera scan or visual inspection to confirm the repair is sound. We provide photos of the completed work, a written summary of what was done, and our 90-Day Done Right Promise in writing. If anything isn’t right, we make it right. No arguing, no paperwork chase.
