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.

Why Top Hat Chimney Is North Bay Shore’s Preferred Chimney Liner & Rebuild Company
Wendell Pike founded Top Hat Chimney in 1999, and he still answers the phone himself half the time. North Bay Shore homeowners call us because they want a name they can verify, not a rotating crew from a national outfit that quoted one price on the phone and a different one at the door.

We know the streets here. We’ve worked off Udall Road, around Pine Aire Drive, and through the blocks near the Southern State Parkway. When a Nor’easter tears up flashing on a South Shore chimney, we’re already scheduling inspections in North Bay Shore because we know the salt-laden wind off Great South Bay hits exposed brick harder than inland towns. The sweep who shows up is background-checked, in uniform, and gives you an arrival window that actually holds. And you’ll see Wendell again at the hardware store on Saturday.
Our Chimney Liner & Rebuild team has handled hundreds of oil-to-gas conversion flues in this part of Suffolk County. We know what a 60-year-old clay tile looks like when it’s been condensing gas exhaust for two decades. We know which Nor’easter seasons hit North Bay Shore hardest. And we know the Town of Islip inspection standards that catch these problems at the worst possible moment, which is usually three days before closing.
Our Chimney Liner & Rebuild Services in North Bay Shore
Stainless Steel Liner
Stainless is the standard fix for North Bay Shore’s oil-to-gas conversion problem. A DuraFlex stainless liner sized correctly for your gas furnace or boiler stops the condensation that’s been eating your mortar joints from the inside out. Most homes in North Bay Shore need a 5.5″ or 6″ liner to replace the old 8″ clay flue that was built for an oil burner. The smaller, properly sized passage actually drafts better and keeps exhaust gas hot enough to vent cleanly.
Flexible Liner
For chimneys with slight offsets or interior offsets that would require demolition to run a rigid liner, a flexible stainless liner snakes through the existing flue and locks in place. It’s the practical choice for a lot of North Bay Shore Capes and splits built between 1950 and 1975, where the flue path isn’t perfectly straight. We size it, insulate it where code calls for it, and connect it properly at the appliance.
Liner Replacement
If your existing metal liner is rusted through, separated at the seams, or was installed wrong by someone who didn’t know what they were doing, replacement is the fix. We pull the old liner, inspect the surrounding masonry, and often find hidden voids behind the brick that need attention before the new liner goes in. Our camera inspection gives you footage of exactly what we found before we quote the job, so you never take our word on faith. You see it yourself.
Partial Rebuild
North Bay Shore’s exposed chimneys take a beating from salt-laden air off Great South Bay. Spalled brick faces, eroded mortar joints, and cracked crowns are normal at 50-70 years of service. A partial rebuild means taking down the damaged courses, usually the top four to six bricks, and relaying them with fresh mortar and brick matched to your existing masonry. We also pour a new crown with proper overhang and a cap that keeps water out of the flue. This is the job that turns a failed inspection into a passed one in under a week.

Trusted Brands We Service in North Bay Shore
We install and service liners and chimney systems from DuraFlex, Famco, and HeatShield, and we keep common parts in stock for fast turnaround on North Bay Shore jobs. DuraFlex stainless liners are our go-to for gas conversion flues because they hold up to years of condensation when sized and installed correctly. Famco caps and dampers show up on most of our rebuilds around North Bay Shore, and HeatShield’s resurfacing system is sometimes the right call when the flue is mostly sound but needs a sealing coat. We’ll tell you which one fits your chimney, and more importantly, when none of them are needed.
Common Chimney Liner & Rebuild Problems We See in North Bay Shore Homes
- Oil-to-gas conversions with an unlined or oversized flue. Your 1962 chimney was built for an oil boiler, which vented hot exhaust through a big clay tile. A gas furnace vents cooler exhaust at lower pressure. The result is chronic condensation that eats mortar joints from the inside out and leaves hidden voids behind the brick face.
- Salt-driven spalling on exposed brick. North Bay Shore sits just north of Great South Bay, and the persistent salt-laden moisture accelerates brick face spalling and mortar erosion on the upper courses. By fall, chimneys that looked fine in June can have loose bricks at the top, which is a safety issue and an inspection failure.
- Nor’easter flashing and cap failures. A nor’easter tracking up the South Shore will flip a light cap or tear flashing in a single storm. Water gets into the smoke chamber and firebox. One winter of freeze-thaw cycling after that turns a minor crack into a full flue-liner replacement.
- Third-degree creosote glaze in a converted flue. On a split-level off Udall Road, our crew pulled a cracked clay-tile flue that had been serving a gas furnace unconverted since the 1980s. The liner was glazed with third-degree creosote and the brick face showed salt-driven spalling from Great South Bay moisture. We installed a DuraFlex stainless liner, rebuilt the top six courses of brick, and poured a new chimney crown. The homeowner’s pre-sale inspection passed the same week.

FAQs - Chimney Liner & Rebuild in North Bay Shore
The short answer is the oil-to-gas conversion history. Most North Bay Shore homes were built between 1950 and 1975 with masonry chimneys sized for oil-fired boilers. When those homes converted to natural gas, the oversized clay-tile flues were rarely relined. The result is chronic condensation that corrodes the flue from the inside, and Town of Islip building inspectors routinely flag unlined or unapproved gas appliance connections during pre-sale inspections. A stainless liner rebuild fixes the finding, often within the inspection period. Call (934) 935-3847 and we’ll get you a written estimate fast.
The salt air itself attacks the exterior masonry more than the liner, but the pattern matters. Salt-laden moisture off Great South Bay accelerates spalling on exposed brick faces and mortar erosion on the top courses. When that moisture gets behind the brick through a cracked crown or failed flashing, it freezes and thaws through the winter and can crack the clay tile behind it. A stainless liner protects the flue from the inside, but the exterior masonry still needs a sound crown and cap to keep bay moisture out. If you’ve got spalled brick on the upper courses, get it looked at before fall. Call (934) 935-3847.
You can reline one flue and leave the others. It’s done regularly in North Bay Shore, where larger properties often have two or three flues serving a furnace, a water heater, and a fireplace. What we look for is whether the other flues are actively used and in what condition. If a second flue is connected to a gas appliance and shows the same condensation damage, we’ll tell you it should be done now rather than later. But you’ll see the camera footage and make the call. No pressure. Call (934) 935-3847 for an honest assessment.
As soon as the storm clears and you can safely get on the roof. Nor’easters tracking up the South Shore regularly damage chimney caps, crowns, and flashing in North Bay Shore. The faster you catch a shifted cap or torn flashing, the less water gets into the smoke chamber. One winter of freeze-thaw cycling after a nor’easter can turn a minor flashing tear into a full flue-liner replacement. If you see water staining on the ceiling near the chimney or hear dripping in the firebox, call us at (934) 935-3847 that week.
If the fireplace is connected to a gas appliance and venting through an old clay flue, yes. The liner requirement isn’t about how often you use the fireplace. It’s about the condensation that forms every time the gas appliance runs, even if the fireplace itself stays cold. That moisture is what corrodes the clay tile and eats the mortar from the inside. The fire you light a few times a year is not the problem. The gas appliance connected to the same flue is. Call (934) 935-3847 and we’ll explain what your specific setup needs, using camera footage so you can see the condition yourself.
