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 Plainview
Most of the chimneys Wendell and his crew inspect in Plainview were built between 1955 and 1965, with clay tile liners sized for oil furnaces. That became a problem the moment Nassau County homeowners started converting to gas. The old flue is too big, it condenses, and the Town of Oyster Bay won’t sign off on the new appliance until the liner is corrected. Chimney Repair in Plainview like a stainless steel liner installation or partial rebuild typically runs $2,800 to $6,500 depending on flue height and access, and most jobs are completed in a single day. Call Top Hat Chimney at (516) 968-5380 and you’ll talk to a live person, not a call center.
Chimney Liner & Rebuild Services We Handle in Plainview
We work across Plainview’s mid-century neighborhoods every week, from the ranches off Old Country Road to the split-levels near the Fairfield development and the Cape Cods north of the LIE. When we say we know your chimney, we mean the exact model: a 1962 masonry chase with two flues, one for the fireplace, one for the furnace, and neither one relined since the day it was built. We offer Chimney Liner & Rebuild services with a simple standard: the camera footage comes first, the recommendation second, and the price never moves once it’s quoted.
Because this page is about Chimney Liner & Rebuild in Plainview, we’ll skip the generic stuff. You want to know what actually fails on a Plainview chimney, what it costs, and whether it can wait. That’s below.

Our Chimney Liner & Rebuild Services in Plainview
Stainless Steel Liner
The most common job we do in Plainview homes right now is pulling out the old clay tile flue and dropping in a continuous stainless steel liner. Why stainless? Plainview’s oil-to-gas conversion wave demands it. The old oil flue was built to vent hot, dry exhaust at a large diameter. A modern gas furnace runs cooler and produces acidic condensation. That condensation eats clay tile. It also leaks through the cracks those 60-year-old tiles already have. A correctly sized stainless liner solves the condensation problem, meets Oyster Bay code, and the town inspection passes. On a typical Plainview ranch with a single-story flue, expect $2,800 to $4,200 installed.
Flexible Liner
When the existing flue has offsets or a bend we can’t work around, we use a flexible stainless liner. Plainview chimneys built in the early 1950s sometimes have odd chase configurations that make a rigid liner impractical. Flexible liners from DuraFlex handle those curves without compromising the flue’s integrity. The job runs closer to $3,200 to $4,800 on a two-story Plainview split-level. We stock the common sizes on the truck, so we’re not running back and forth across Jericho Turnpike to finish the job.
Liner Replacement
If you already have a metal liner that’s showing rust, pinholes, or a failed connection at the appliance, replacement is usually the cleanest fix. Plainview’s humid summers and the salt air that pushes in from the south shore both accelerate corrosion on older galvanized liners. That’s a key reason we recommend stainless over galvanized for any Plainview liner replacement, regardless of what was there originally. A straightforward liner replacement in a single-flue chimney runs $2,500 to $3,800.
Partial Rebuild
A partial rebuild addresses the top of the chimney: our Chimney Cap & Crown in Plainview, the top two or three courses of brick, and the flashing. Plainview’s freeze-thaw cycle is brutal on this section because it’s the most exposed. We see spalled brick and cracked crowns on nearly every unrepointed 1950s chimney we inspect. A partial rebuild in Plainview typically runs $3,500 to $5,500 depending on how far down the damage goes. If the firebox or smoke chamber is also compromised, we’ll show you the camera footage before recommending anything beyond that.
Trusted Brands We Service in Plainview
Wendell has worked with the same manufacturers for decades because their parts hold up and their warranties are real. We install and service liners and components from HeatShield, Gelco, and Olympia Chimney. If your existing Plainview chimney already has a liner from one of these brands, we can service it directly, no need to rip out a system that’s still doing its job. We keep the common Plainview-sized parts on hand, which means most liner jobs are done in one visit. We don’t sell you a brand because it’s on the truck. We sell you the one that matches your flue and your appliance.
Common Chimney Liner & Rebuild Problems We See in Plainview Homes
- Oil-to-gas conversion gone wrong (or not gone at all). Plainview homeowners switch to gas, the old oversized oil flue stays in place, and the new furnace condenses inside the chimney. The first sign is usually a water stain on the ceiling near the chase. The fix is a correctly sized stainless liner, not a patch.
- Frost-driven spalling on 60-year-old brick. Plainview winters push the temperature across the freezing point dozens of times. Water gets into the brick, freezes, expands, and pops the face off. We see this on nearly every unrepointed chimney north of the Southern State Parkway.
- Cracked chimney crowns and failed flashing. Nor’easters drive wind-blown rain into hairline cracks. The water works down into the flue and the chase. By the time you see staining inside, the liner is often already rusted through.
- Clay tile liners that were never rated for this climate. The original 1950s and 1960s clay tiles were fine for oil exhaust. They were never designed to handle decades of freeze-thaw plus the acidic condensation from a modern gas appliance. Plainview’s housing stock is now squarely in that failure window.
On a split-level near the Fairfield development, our crew found the oil flue badly spalled and the clay liner cracked at the smoke chamber after decades of Long Island freeze-thaw cycles. We removed the failed liner, installed a DuraFlex stainless steel liner sized for the new gas furnace, and rebuilt the chimney crown with our Fireplace Services in Plainview providing a proper cap and flashing. The town inspection passed the same week. That’s the norm on these Plainview conversions, not the exception.
Pricing for Chimney Liner & Rebuild in Plainview, NY
A stainless steel liner install in Plainview runs $2,800 to $4,200 for a single-story flue. A two-story split-level with a flex liner runs $3,200 to $4,800. A partial rebuild (crown, top courses, flashing) runs $3,500 to $5,500. A full chimney rebuild from the roofline up runs $7,000 to $12,000. Plainview labor rates are consistent with the rest of Nassau County, but what changes between quotes is usually scope, not rate. We price the job from the ground, by looking at the actual flue with a camera, before any tool comes off the truck. The number you get on the phone is the number on the invoice. Call (516) 968-5380 and we’ll walk through it with you.
And because we know what it’s like to get burned: we offer a free second opinion on any written estimate you’ve already received from another company. If we can fix the problem for less, we’ll say so. If the other company is right, we’ll say that too.

FAQs - Chimney Liner & Rebuild in Plainview
Yes, in almost every case. The Town of Oyster Bay requires the flue to be correctly sized for the new gas appliance before they’ll sign off on the installation. The original clay tile flue in your Plainview home was sized for oil exhaust, which is hotter and drier. Gas exhaust is cooler and wetter. The oversized flue won’t draft properly, and the condensation will eat through the old clay tile. A stainless steel liner sized for the new furnace is the standard fix. Call (516) 968-5380 and we’ll verify what your flue actually needs.
Every year, burn or no burn. Plainview’s freeze-thaw winters and humid summers put more stress on a liner than most homeowners realize. A cracked liner that’s caught early can sometimes be repaired with a resurfacing product like HeatShield. A liner that’s ignored for another five years usually means full replacement. The camera inspection takes about twenty minutes and shows you exactly what we see. Once a year, burn or no burn. Chimneys break in the off-season too.
Water. Specifically, water that gets into hairline cracks, freezes, expands, and then melts. Plainview’s temperature crosses the freezing point dozens of times each winter. That cycle slowly breaks apart the concrete crown and loosens the flashing where the chimney meets the roof. Nor’easters then drive wind-blown rain into those gaps. A cracked crown is one of the most common things we find on 1960s Plainview chimneys. The fix is a rebuilt crown with a proper cap and sealed flashing, not caulk. We talk more about that on our Chimney Liner & Rebuild service page.
Yes, and that’s exactly what we do in most Plainview homes. The original masonry chase is usually still structurally sound. We remove the failed clay tile if it’s cracked or spalled, then drop a stainless steel liner down the existing flue. It works with the chimney you already have, not against it. The installed liner is sized for your new furnace, vented properly, and inspected by the town. No demolition, no brick work unless the top of the chimney also needs attention.
A partial rebuild addresses the top of the chimney: the crown, the top courses of brick, and the flashing. That’s a $3,500 to $5,500 job in Plainview. A full rebuild means taking the chimney down to the roofline or below and rebuilding it from scratch, which runs $7,000 to $12,000 depending on height and access. Wendell will show you the camera footage so you can see exactly which one you need. If a partial rebuild will do the job safely, that’s what we’ll recommend. Your flue doesn’t care how the fire looks. It cares how it breathes.
