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 Mineola
Chimney liner replacement in Mineola typically runs $1,800 to $4,200 for a stainless steel system installed in a single afternoon, and partial rebuilds start around $2,500 depending on how many brick courses need re-pointing. We’re in Mineola every week, and we’ve been chasing leaks and cracked flue tiles in these 1920s-through-1950s Colonials and Capes long enough to know exactly what the village inspector wants to see before he signs off on a gas conversion. Call (516) 963-1068 and we’ll come out with a camera, not a sales pitch.
Why Top Hat Chimney Is Mineola’s Preferred Chimney Liner & Rebuild Company
We’re not a franchise that rotated a truck into Nassau County last spring. Wendell Pike founded Top Hat Chimney in 1999, and over 29 years he’s been inside more Mineola chimneys than he can count – from the brick Colonials off Jericho Turnpike to the Tudor-influenced homes near the LIRR station. Ask anyone on your street. The name on the truck is the name that shows up at your door, and the license number is published for anyone to check.
Mineola homeowners call us because the estimate we give on the phone is the number on the invoice. Period. No door-shuffle, no “discovered damage” upcharge. Every job is backed by our 90-Day Done Right Promise in writing – if it’s not right, one call brings Wendell and his crew back at no additional cost. And when you call, a live person answers. Around the clock, seven days a week. It may well be Wendell himself picking up at 2 a.m. when you smell something odd from the fireplace.
Our Chimney Liner & Rebuild team works with DuraFlex, HeatShield, Gelco, and Olympia Chimney products, and we stock common liner components locally so Mineola jobs don’t stall waiting on backorders. Background-checked, uniformed technicians give you a real arrival window and call if it slips. No trip charge inside the county. And if you have a written estimate from another company, we’ll give you a free second opinion – because you should know what you’re actually paying for.
Our Chimney Liner & Rebuild Services in Mineola
Here’s what we handle most often for homeowners in Mineola. Every job starts with a camera inspection you can watch yourself, because nothing gets recommended unless you can see the evidence with your own eyes.
Stainless Steel Liner
If your Mineola home still has its original clay tile flue from the 1930s or 1940s, a DuraFlex stainless steel liner is the standard fix. We size the liner to match the BTU rating of whatever appliance vents through it – that’s the exact detail Nassau County inspectors look for on an oil-to-gas conversion permit. A properly sized stainless liner in Mineola typically runs $1,800 to $3,200 installed, depending on chimney height and access.
Flexible Liner
For chimneys with slight offsets or tight access – common in the one-and-a-half-story Capes around Willis Avenue – a flexible liner slips down the flue without opening up interior walls. It’s not always the right answer; we’ll tell you plainly if your chimney is too compromised for it. But when it works, it’s usually the least invasive way to bring a failing flue back to code, and costs run roughly $1,700 to $2,800 in Mineola.
Liner Replacement
When the old clay tile liner has started separating – and after decades of acidic oil-flue condensate, many have – replacement is not an upsell. It’s the repair. In Mineola, liner replacement jobs often come to us mid-conversion, after a gas contractor flags the oversized flue and the permit stalls. Expect $2,000 to $3,800 depending on whether we’re removing old tile or just inserting a new liner.
Partial Rebuild
Freeze-thaw cycles off Long Island Sound work on exposed chimney crowns year after year in Nassau County. The crown cracks, water gets in, and the top three to ten courses of brick start spalling. A partial rebuild – new crown, new flashing, rebuilt brick courses – runs $2,500 to $5,500 for most Mineola chimneys. It is far cheaper to rebuild a crown than a full stack, and we’ll do it before the first October cold snap if you call now.
Full Chimney Rebuild
Rare, but it happens – especially on the older Tudor-influenced homes near Mineola Memorial Park where the original mortar has turned to sand. A full rebuild from roofline up typically starts around $6,000 in Mineola. We’ll never recommend one without showing you the camera footage and explaining, in plain English, why a partial repair won’t hold.

Trusted Brands We Service in Mineola
We stock DuraFlex stainless steel liner kits, Gelco caps and dampers, and Olympia Chimney components, which means most Mineola liner replacements and rebuilds don’t wait on parts. We also service and install Famco and Copperfield products. If you’ve got an older Gelco cap that’s rusted through or an Olympia liner showing its age, we can match the part rather than sell you a whole new system you don’t need. Your flue doesn’t care how the fire looks. It cares how it breathes.
Common Chimney Liner & Rebuild Problems We See in Mineola Homes
- Separated clay tile joints from decades of oil soot. Mineola’s 1920s-1950s homes were coal-heated first, then oil. Acidic oil-flue condensate ate through the mortar between clay tiles, and by the time a gas conversion starts, the liner is cracked and venting into wall cavities. The village inspector won’t pass it.
- Spalled crowns and cracked brick faces from freeze-thaw cycles. Moisture-laden air off the Sound seeps into micro-cracks every winter, freezes, and pops the surface right off the brick. You won’t notice until water stains show up on attic beams around the chimney chase.
- Oversized coal-era flues on modern gas furnaces. Early Mineola gas retrofits vented mid-efficiency furnaces into chimneys built for coal draft. The flue is too big, the draft collapses, and no damper adjustment fixes it. The fix is a correctly sized stainless liner.
- Vented gases draining through cracked mortar joints without a liner at all. Some Mineola chimneys were never lined in the first place – just bare masonry. That’s legal in some older homes, but it is not safe, and a gas conversion permit will force the issue. We run the camera, show you the footage, and give you a straight answer.
Pricing for Chimney Liner & Rebuild in Mineola, NY
Here are honest numbers for Mineola’s market. A stainless steel liner installed in a typical 2-story Colonial runs $1,800 to $3,200 depending on flue length and access. A flexible liner slightly less, $1,700 to $2,800. Liner replacement on a 1930s chimney where we remove the old clay tile first runs $2,000 to $3,800. A partial rebuild with a new crown and flashing: $2,500 to $5,500. A full chimney rebuild from the roofline up starts around $6,000.
What moves the price: chimney height, how many offsets are inside the flue, whether scaffolding or a lift is needed, and how much brick has to come out before the rebuild starts. We give the number up front, before a single tool comes off the truck, and it is the number on the invoice. No trip charge inside the county, $40 off any repair over $200, and seniors and veterans always get 10% off. Call (516) 963-1068 for an exact quote – estimates are free.

FAQs - Chimney Liner & Rebuild in Mineola
Yes. Nassau County requires a building permit for chimney liner installations, and the inspector will check that the liner diameter matches the BTU rating of your new gas appliance. If your 1930s clay-tile flue is oversized or cracked, the permit stalls until a stainless liner is in place. We handle the sizing and paperwork details so the job passes the first time. Call (516) 963-1068 and we’ll walk you through what your specific chimney needs.
You ask for the camera footage, and if they won’t show you, you call someone else. We run a Level 2 camera inspection on every liner job and you watch the screen with us. Cracked clay tiles are visible – separated joints, missing sections, glaze from oil condensate. Nothing is recommended unless you can see the damage for yourself. We recently relined a 1938 Colonial near Mineola Memorial Library where the original 8×12 flue had separated at three joints and was coated in an acidic oil-condensate glaze. The homeowner watched the whole scope on camera before approving a single repair. That’s how it should work.
Usually, yes – if the damage is caught before water reaches the brick courses below. A crown repair or replacement on a Mineola chimney runs $800 to $1,800, far less than a partial rebuild at $2,500 to $5,500. But if freeze-thaw cycles have already spalled the top courses of brick, patching the crown alone won’t hold. We’ll show you the difference on camera and tell you which one you actually need. Call (516) 963-1068 for an inspection and a straight answer.
Because your chimney was built for coal and oil, not a modern high-efficiency gas furnace. When the flue is oversized, the hot exhaust can’t draft properly – the gases cool and stall inside the chimney, which means condensation, carbon monoxide buildup, and a draft problem no damper adjustment fixes. A correctly sized stainless steel liner solves it by matching the flue diameter to the furnace’s BTU rating. That’s exactly what the Nassau County inspector checks. Call (516) 963-1068 and we’ll size it right before your conversion stalls further.
No, and do not burn another fire until it’s inspected. Chunks of clay tile in the firebox means the flue liner is actively delaminating, likely from decades of thermal cycling and acidic oil-flue condensate. Those pieces are falling from somewhere, and the gap they left behind is venting combustion gases into the wall cavity, not up the chimney. First-degree creosote is a brush job. Third-degree is a glaze – catch it early. Call (516) 963-1068 and we’ll run a camera up the flue this week.
