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.

AfterTrusted Chimney Liner & Rebuild for Commack Homeowners
If you’re wondering how much Chimney Liner & Rebuild costs, work in Commack typically runs between $1,900 and $6,500 depending on whether we’re dropping a new stainless liner into your existing flue or rebuilding the chimney from the roofline up. Most liner replacements take one day, and we’ll show you camera footage of exactly what we found before you spend a dime. Wendell Pike founded Top Hat Chimney in 1999, and he’s been inside more Commack chimneys than he can count. If you’re seeing flaking tile, rust streaks, or crumbling mortar, call (631) 502-3612 and we’ll tell you straight what needs doing and what can wait.
What matters here is that your flue does not care how the fire looks. It cares how it breathes. A cracked liner leaks heat and gas into wall cavities and attics. A spalling brick chimney lets water in and falls apart from the inside. We fix both, with a written 90-Day Done Right Promise on every single job. The number you hear on the phone is the number on the invoice, and Wendell puts his name on the work because he runs into you again on Saturday.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is the modern standard for chimneys venting a furnace, boiler, or water heater. In Commack homes built in the 1960s and 70s, the original clay tile liners crack from decades of heating and cooling, and a stainless liner gives you a sealed, continuous flue that handles exhaust safely. We install rigid and flexible stainless liners sized to your appliance, not a one-size-fits-all guess. Wendell measures the flue, shows you the old liner on camera, and only then quotes the replacement.
Flexible Liner
A flexible liner bends through offsets and turns in an existing chimney where a rigid pipe would never make it. Most Commack chimneys have at least one offset, and forcing a liner around it is where amateurs tear the new pipe and call it done. We use continuous-wall flexible liners from brands like DuraFlex, pulled carefully, not yanked. You get a smooth, uninterrupted exhaust path, and we test the draft before we pack up.
Liner Replacement
Liner replacement is what you need when the existing clay tiles are cracked, spalled, or missing entirely. You can not patch a failed liner and sleep well. We remove the damaged sections, inspect the smoke chamber and crown, and install a properly sized new liner system. The camera footage and a plain-English verdict, every time, no exceptions. If the old liner is sound and only needs minor repair, we’ll tell you that too, and we will not sell you a replacement you don’t need.
Partial Rebuild
A partial rebuild addresses the portion of the chimney above the roofline, which takes the worst of Commack’s freeze-thaw cycles every winter. You see spalled bricks and crumbling mortar joints up top while the lower chimney is still solid. We take down the damaged section, rebuild it with proper brick and mortar, install a new crown, and leave the rest of the stack alone. It is a frank repair, not a full teardown, and it costs a fraction of a rebuild.
Full Chimney Rebuild
A full rebuild is the big job, and we only recommend it when the structural damage runs deep into the stack. That happens with older Commack chimneys that were built without a proper crown or have had decades of water intrusion. We tear the damaged chimney down to the point of sound masonry and rebuild it correctly, including a cast-in-place crown that sheds water the way it should. Wendell will walk the roofline with you in photos, show you the failed sections, and explain exactly why a rebuild is the honest call rather than another patch job.
Liner Repair
Liner repair covers situations where the damage is localized, like a single cracked tile section or a failed joint, and the rest of the liner is still sound. We do not reline for the sake of it. HeatShield and similar repair systems can resurface limited damage when the existing flue is in good shape overall, and we will show you the before and after footage. If the liner is too far gone, we’ll say so plainly and quote the replacement.

Brands We Service for Chimney Liner & Rebuild
We install and service liners from brands we trust, and we will tell you why we trust them. DuraFlex flexible liners are a workhorse in Commack chimneys: they bend through offsets without kinking, and we have installed them for years without a callback on the liner itself. Olympia Chimney makes strong stainless components and caps that hold up to coastal air better than cheaper imported hardware, which matters here on Long Island.
For liner repair, HeatShield is a specific tool for a specific problem. It is not a substitute for a liner that has failed outright, and we will not sell it as one. Famco and Copperfield make the caps, chase covers, and termination hardware we use on rebuilds, and we stock the parts that match the systems we install. Whether you have one of those brands or something else entirely, we can help, and we will show you the spec before we order anything.
Signs You Need Chimney Liner & Rebuild Right Now
- Chunks of clay tile in the firebox. When you find terracotta shards at the bottom of your fireplace, the flue liner is actively shedding. Each missing tile section is a gap where heat and exhaust can reach the surrounding masonry, and Commack fire departments run on visible smoke, not invisible flue gas. Get it on camera before you light another fire.
- White staining or efflorescence on the chimney exterior. That white powder is salt being pulled through the brick when water is inside the masonry. In Commack’s freeze-thaw winters, trapped water freezes and spalls bricks from the inside. Efflorescence is the early warning that a rebuild may be coming, not a cosmetic footnote.
- Rust streaks or peeling paint around the chimney chase. Rust streaks mean moisture is mixing with steel liner components or the chase top is failing. Once rust has a foothold, the damage accelerates fast, and a $400 chase cover now beats a $4,000 rebuild later. Wendell will tell you which side of that line you are on.
- Smoke backing into the house or a sulfur smell upstairs. A cracked liner can not maintain draft, which sends exhaust where it was never meant to go. Carbon monoxide is not dramatic to describe; that is exactly why we take it seriously. If you smell anything odd when the furnace runs, call (631) 502-3612 and have it looked at before the next cold snap.
- Visible cracks in the chimney stack or a leaning chimney. A leaning chimney is a structural failure, not a maintenance item. Cracked masonry that lets water and exhaust through the stack only gets worse, and it puts people and property below at risk. We would rather do a partial rebuild now than a full rebuild after a storm.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
The look. Wendell or one of his background-checked, uniformed crew members arrives at your Commack home, climbs up, and examines the chimney from crown to firebox. You get a real arrival window, and if that window slips, we call you. No compounding schedule surprises.
- 2
The camera. We run a camera down the flue and show you everything on the spot. Cracked tiles, failed joints, water staining, prior work that did not hold up. You do not have to take anyone’s word for a single sentence. The camera footage and a plain-English verdict, every time, no exceptions.
- 3
The number. We give you upfront pricing before a single tool comes off the truck. The number on the phone is the number on the invoice, and it covers the full scope we discussed, not a stripped-down opener. If you have a written estimate from another company, bring it. We will give you a free second opinion, and we will not bad-mouth them; we will show you our numbers.
- 4
The work. We do the repair or rebuild in the sequence we agreed, protecting your roof and yard as we go, and we leave the job site cleaner than we found it. For liner work, we test the draft before we finish. For rebuilds, we cure the crown correctly so it sheds water instead of absorbing it.
- 5
The promise. Every completed job carries our 90-Day Done Right Promise in writing. If it is not right, one call brings Wendell back, no charge. That is not a tagline. It is printed on the paperwork we hand you before we shake your hand and head to the next house.
How Much Does Chimney Liner & Rebuild Cost in Commack?
A standard stainless steel liner replacement in Commack typically runs $1,900 to $3,800, depending on flue height, liner diameter, and whether we are venting a fireplace or a furnace. A partial rebuild above the roofline usually lands between $2,500 and $4,500. A full chimney rebuild starts around $4,800 and can go to $6,500 or more on a tall two-story stack with extensive damage. Those are honest ranges, not teaser numbers.
What moves the price: chimney height (roofline access matters more than most folks expect), liner diameter and fuel type, the condition of the crown and smoke chamber, and whether scaffolding is needed. What should not move the price: the guy on the phone saying one thing and the guy at the door saying another. We do not play that game. Our estimate is free, it is itemized, and it includes the camera inspection. If a liner can be repaired instead of replaced, we will quote the repair and tell you why. Seniors and veterans always get 10% off, and any repair over $200 takes $40 off right now.

Frequently Asked Questions - Chimney Liner & Rebuild in Commack
A chimney liner is the sealed passage inside your chimney that carries exhaust up and out while protecting the surrounding masonry and your home from heat. In Commack, most older homes have clay tile liners that crack with age, and a cracked liner can leak carbon monoxide into wall cavities and living spaces. The fix is either restoring the existing liner or installing a new stainless steel system. We show you the camera footage before we recommend anything.
Most stainless liner replacements in Commack are completed in one day, from setup to draft test. A partial rebuild above the roofline usually takes one to two days depending on weather. A full chimney rebuild can run three to five days. Wendell gives you a real schedule before work starts, and if it changes, we call you first.
A typical liner replacement here runs $1,900 to $3,800, while a full chimney rebuild starts around $4,800. The biggest factors are chimney height, liner diameter, appliance type, and the condition of the surrounding masonry.
