Chimney Liner & Rebuild in Brentwood - Inspected on Camera, Then Priced in Writing

Fast, Reliable Chimney Liner & Rebuild Across Brentwood

If you live in Brentwood and your chimney is pushing 50 or 60 years old, the liner inside it is likely the original clay tile, and it’s probably telling you something. White streaking down the brick, a faint musty smell in the room, a draft that never quite pulls right. A cracked or missing liner is not a cosmetic problem. It’s how flue gases, including carbon monoxide, find their way back into your house instead of up and out. Top Hat Chimney has been repairing and rebuilding chimneys across this part of Long Island since 1999, and Wendell Pike and his crew know the Brentwood housing stock better than most. If you want a straight answer about what’s going on inside your flue, call us at (516) 968-5380 and we’ll come take a look.

Why Top Hat Chimney Is Brentwood’s Preferred Chimney Liner & Rebuild Company

Brentwood is not a coastal hamlet, and that matters more than most homeowners realize. The freeze-thaw cycles here are sharper than what Bay Shore gets, and they work on brick and mortar all winter long. We’ve been inside enough Brentwood chimneys to know which ones are going to need a liner before we even set up the ladder. When someone on Candlewood Road or anywhere off Washington Avenue calls, we know what to expect before we arrive. The answer isn’t “you need everything replaced.” Sometimes it’s a section of liner. Sometimes it’s a crown. We’ll tell you which one, and we’ll show you the camera footage to prove it.

You’ll get a live person on the phone, day or night. Not a call center. Wendell answers when he can, and the rest of the crew steps in when he can’t. Every technician who shows up at your door in Brentwood is background-checked and in uniform, with a real arrival window that we actually honor. Our pricing is set before a single tool comes off the truck. The number you hear on the phone is the number on your invoice. If the job isn’t done right, our 90-Day Done Right Promise puts that in writing: one call brings us back at no additional cost.

Our Chimney Liner & Rebuild Services in Brentwood

Stainless Steel Liner

When a Brentwood home converted from oil to gas without a properly sized liner, the original clay tile flue was almost always too big for the new gas appliance. That creates cold flue gases that condense inside the flue, and the acidic condensate eats away at old mortar joints. A correctly sized stainless steel liner fixes that. We install liners from DuraFlex and Copperfield, sized for the actual BTU output of your furnace or boiler, not whatever the chimney happened to be built for in 1962.

Liner Replacement

If your existing liner is cracked, spalling, or rusted through, taking it out and putting a new one in is often the single most important repair you can make to a Brentwood home. We see a lot of original 6 to 8 inch clay tiles that are 50 to 70 years old, with open mortar joints between them. That’s not salvageable. We’ll remove the old liner, inspect the flue walls, and install a replacement sized for the appliance you actually run now, not the oil burner the house was built around.

Partial Rebuild

Not every Brentwood chimney needs to come down to the roofline. When the damage is concentrated in the top few courses of brick, the crown, or the area around the smoke chamber, a partial rebuild is the right call. We’ll remove the failing brick and mortar, relay it properly, and set a new crown that actually sheds water. What we won’t do is tell you a partial rebuild will fix a liner problem. Those are two different jobs, and you deserve to know which one you’re paying for.

Full Chimney Rebuild

Some Brentwood chimneys have been neglected long enough that the structure itself is unsafe. Single-wythe brick construction, decades of inland freeze-thaw cycles, and a crown that stopped doing its job years ago add up. When a full rebuild is necessary, we’ll tell you plainly, show you why, and then rebuild it square and plumb from the roofline up, with a new liner, new flashing, and a cap that’s made for Long Island weather. We don’t take rebuilds lightly, and we won’t recommend one unless the chimney genuinely needs it.

Trusted Brands We Service in Brentwood

We install and service liners and components from DuraFlex, Copperfield, HeatShield, and Gelco. These are the names we trust on our own jobs because they hold up. When you call about a stainless steel liner or a rebuild in Brentwood, we typically have what we need on the truck or at our shop, which means less waiting and fewer return trips. If a brand-specific part is required, we can usually source it quickly without leaving you hanging for weeks.

Common Chimney Liner & Rebuild Problems We See in Brentwood Homes

• Oversized clay tile liners from oil-to-gas conversions. Many Brentwood homes built in the 1950s through early 1970s vented large oil burners through 8-inch flues. A 90k-BTU gas boiler venting into that same flue runs much cooler, and the condensation it produces eats mortar joints and leaks flue gas within 15 to 20 years of conversion. This is the single most common liner problem we diagnose in the hamlet.
• Freeze-thaw cracking in single-wythe brick chimneys. Brentwood sits far enough inland that it loses the thermal buffering of Great South Bay, so brick and mortar freeze and thaw more often than in coastal communities just a few miles south. Crowns that were never waterproofed crack sooner here, and the damage works its way down into the chimney structure.
• Rusted galvanized flashing and caps from nor’easters. Wind-driven rain from coastal storms finds its way into flashing seams and cap joints. Once galvanized steel starts rusting, water gets behind it and accelerates deterioration where the liner meets the smoke chamber. We replace galvanized with stainless as a matter of course.
• Efflorescence as an early warning sign. That white, chalky streaking on the outside of many Brentwood chimneys? It means moisture is migrating through the masonry and carrying salts with it. It’s usually the first visible sign that your liner or crown is failing, and it’s worth having a camera inspection before it becomes a structural problem.
