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 North Bay Shore
Chimney liner and rebuild work in North Bay Shore usually runs between $2,800 and $7,500, and the job takes one to two days once we’re on site. The cost depends on liner length, whether we’re doing a partial or full rebuild, and how much crown work the coastal air has forced on you. If you’re calling from North Bay Shore, the phone rings at (631) 318-8656, and a live person picks up. Not a menu. Not a call center.
Wendell Pike founded Top Hat Chimney in 1999, and he still answers the phone plenty of nights. Our Chimney Liner & Rebuild crew knows the postwar Capes and ranches around Udall Road, Spur Drive, and the blocks off Pine Aire Drive. We know what bay moisture does to a 1950s mortar crown. We know what an oil-to-gas conversion leaves behind in the flue. That local knowledge is why homeowners in North Bay Shore call us instead of a national outfit that rotates a different tech through every season.
Why Top Hat Chimney Is North Bay Shore’s Preferred Chimney Liner & Rebuild Company
Ask anyone on your street. Top Hat has been working chimneys in the Town of Islip and around North Bay Shore for over 29 years, and Wendell puts his name on the work. When we finish a liner job here, you get the 90-Day Done Right Promise in writing. If something isn’t right, one call brings Wendell back. No argument, no re-quote, no phone tree.
Homeowners between 50 and 70 have told us they’ve been burned by chains that quoted one price over the phone and a different number at the door. That’s exactly what we don’t do. The price you hear before a tool comes off the truck is the number on the invoice. Our techs are background-checked, wear uniforms, and give you a real arrival window. If we’re running late, we call. That matters in North Bay Shore, where a lot of the housing stock needs honest chimney work more than it needs a sales pitch.
The local reputation here is built on a simple rule: the camera footage and a plain-English verdict, every time, no exceptions. You see what we see. If your liner can wait, we’ll say so. If it can’t, we’ll show you why.
Our Chimney Liner & Rebuild Services in North Bay Shore
Stainless Steel Liner
A stainless steel liner is the right answer for most North Bay Shore homes that have converted from oil to gas. The old clay tile flue was built for an oil boiler pushing hot exhaust hard. A modern 40,000 BTU gas furnace barely warms that oversized flue, and the condensation that results eats clay from the inside. We install DuraFlex and Copperfield stainless liners sized to the appliance, not to the old chimney. Stainless is also the material that holds up best against the salt air coming off the Great South Bay.
Flexible Liner
Flexible liners make sense when your North Bay Shore chimney has offsets or turns that would require breaking into masonry to run a rigid liner. For many of the 1950s Capes and ranches here, a flexible stainless liner drops down through the existing flue without tearing out brick. It’s faster, it’s less invasive, and it’s still a fully code-compliant fix. Wendell and his crew use flexible liners from DuraFlex and Gelco. The choice between rigid and flexible comes down to the shape of your flue, not a sales target.
Liner Replacement
Liner replacement in North Bay Shore is common for a very specific reason. During the oil-to-gas conversions that National Grid’s gas expansion spurred, many local homeowners swapped the burner and never touched the chimney. The old liner, if there even was one, stayed in place. Years of salt-laden bay air and flaking clay later, the liner is failing. Sometimes we can pull the old liner and drop a properly sized stainless one. Sometimes the surrounding masonry needs repair first. We’ll tell you which one applies before we start.
Partial Rebuild
Partial rebuilds in North Bay Shore usually mean the top five to ten courses of brick above the roofline. Freeze-thaw cycles on the south shore of Long Island work on mortar joints every winter. Add coastal humidity and salt, and the crown cracks, water gets in, and the brick face starts spalling. We rebuild the top section, seal the crown, and install a stainless cap if the old one has rotted. A partial rebuild often costs less than homeowners fear, and it stops the damage before it forces a full rebuild.

Trusted Brands We Service in North Bay Shore
We install and service DuraFlex, HeatShield, Gelco, and Copperfield products. For North Bay Shore specifically, we stock stainless components because they’re the only sensible choice this close to the bay. Galvanized caps and flashing corrode in three to five years here. Stainless lasts a decade or more. If you’ve got an existing liner from one of these brands, we service it. If you need a new one, we’ll recommend the brand that fits your chimney and your budget. Since we stock common parts for North Bay Shore jobs, turnaround is usually faster than it would be for a shop that has to order everything in.
Common Chimney Liner & Rebuild Problems We See in North Bay Shore Homes
- Salt-corroded caps and flashing. Galvanized chimney caps on North Bay Shore roofs fail within three to five years. The salt air from the Great South Bay corrodes the metal, water gets down the flue, and the liner starts rusting or the brick starts spalling. Stainless caps fix this for a decade or more.
- Oversized flues left after oil-to-gas conversion. The 8-inch flue that once vented an oil boiler is now connected to a 40,000 BTU gas furnace. Cold exhaust, weak draft, condensation, and backdraft. In North Bay Shore, this is the single most common relining trigger we see.
- Spalling crowns on 1950s brick. The original mortar crowns on postwar Capes and ranches were never built for 70 years of freeze-thaw cycling half a mile from the bay. Cracks widen, salt air reaches the liner, and the top of the chimney starts crumbling.
- Flaking clay tiles after decades of deferred maintenance. Many North Bay Shore homes have original clay tile liners that haven’t been inspected since the first owner moved in. Salt moisture and heat cycling flake the tiles, restrict draft, and create a real fire hazard inside the flue.

FAQs - Chimney Liner & Rebuild in North Bay Shore
How often should a stainless steel chimney liner be inspected in North Bay Shore compared to inland Long Island?
In North Bay Shore, a stainless steel liner should be inspected every two years. Half a mile inland, where Brentwood starts, the same components can go five years between checks. The difference is salt air. Great South Bay moisture carries salt that accelerates corrosion on caps, flashing, and liner surfaces. You don’t need a full sweep every two years, but you do need eyes on the liner and cap to catch corrosion before it becomes a rebuild. Call (631) 318-8656 to book an inspection, and we’ll give you a written report with camera footage so you can see exactly what’s happening up there.
Why do so many North Bay Shore chimneys need relining after an oil-to-gas conversion?
Because the original flue was sized for an oil boiler, not a gas furnace. When National Grid extended service into the Town of Islip and homeowners swapped for natural gas, the flue stayed exactly as it was. An 8-inch flue venting a 40,000 BTU furnace doesn’t get hot enough to maintain draft, so exhaust cools, condensation forms, and the liner starts flaking or corroding. In North Bay Shore, salt air speeds that corrosion up. Relining with a properly sized stainless liner is the fix. It’s one of the most common jobs we do here.
Does salt air affect a chimney cap more than the liner?
Yes, and it’s not even close. A galvanized cap in North Bay Shore rusts through in three to five years. A stainless liner, properly installed, can last decades. But when the cap fails, water gets down the flue and starts wrecking the liner from the inside. So the cap is the first line of defense. We stock stainless caps for exactly this reason. If you’ve got a galvanized cap up there and you’re within a mile of the bay, plan on replacing it sooner rather than later. Call (631) 318-8656 and we’ll take a look.
Are there specific brands of stainless steel liners better suited for North Bay Shore’s coastal conditions?
We steer North Bay Shore customers toward DuraFlex and Copperfield stainless liners. Both use 316L-grade stainless, which resists the chloride corrosion that salt air causes. Some cheaper liners use 304-grade stainless, which is fine inland but shortens lifespan near the bay. We also use Gelco crowns, which hold up better than original mortar against freeze-thaw and salt moisture. The brand matters less than the grade of steel. We’ll show you the difference before you pay a dime.
What is the most common rebuild need on North Bay Shore chimneys from the 1950s?
The top five to ten courses of brick above the roofline. Freeze-thaw cycles near the Great South Bay have been working on those 1950s mortar joints every winter for 70 years. The original crowns crack, salt air reaches the liner, and the bricks start spalling. Most of the time it’s a partial rebuild, not a full one. We recently relined a 1958 Cape Cod on Udall Road after a gas conversion left an unlined 8-inch flue venting a 40,000 BTU furnace. We installed a DuraFlex stainless liner with a new Gelco crown and stainless cap, resolving chronic backdrafting the homeowner had blamed on a drafty house.
