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.

If your North Merrick home still has its original clay tile liner from the Truman or Eisenhower years, the question isn’t whether it will need work. It’s whether the work gets done before the freeze-thaw cycle turns a hairline crack into a full offset that vents exhaust into the house. Wendell Pike and his crew service North Merrick regularly, and we route a crew here within a few days of your call most of the year.
Why Top Hat Chimney Is North Merrick’s Preferred Chimney Liner & Rebuild Company
Wendell started Top Hat Chimney in 1999, and he still answers calls himself half the time. That’s rare in this trade. National outfits send a salesman who quotes one price and a subcontracted crew that charges another. Wendell’s name is on every invoice, his license number is published, and he backs the work with a 90-Day Done Right Promise in writing. If something’s not right, one call brings him back.
Homeowners around the Merrick Road corridor, North Merrick Avenue, and the blocks off Jerusalem Avenue have had us out for liner work, rebuilds, and second opinions on quotes they didn’t trust. We keep our pricing honest because we run into these people at the Bagel Boss and the school pickup line. Ask anyone on your street. The camera footage and a plain-English verdict come on every job, no exceptions.
Our phone rings to a live person around the clock. No voicemail box, no call center in another state. If Wendell’s on a roof, someone in the office answers and gives you a real arrival window. If that window slips, we call. That’s how a local business should run, and it’s why North Merrick keeps calling us back.
Our Chimney Liner & Rebuild Services in North Merrick
Most North Merrick homes fall into one of two situations. Either the original 1950s clay liner is cracked and a new stainless liner makes sense, or the masonry shell itself is spalling from decades of bay air and needs a partial rebuild along with the liner. Here’s how we handle each.
Stainless Steel Liner
For gas furnaces and water heaters in North Merrick, we install flexible and rigid stainless liners sized to the appliance’s exhaust requirements. The old clay flues in these 1950s Capes and split-levels are oversized for modern gas equipment. That’s the whole problem. A correctly sized stainless liner vents the cooler gas exhaust properly instead of letting it condense inside the flue and eat mortar joints. We carry DuraFlex and Copperfield liners and install them in one to two days on most single-story and split-level chimneys in North Merrick.
Flexible Liner
Flexible liners are the standard fix for chimneys with offsets or slight bends, which most 60-year-old masonry stacks have. We fish them down through the existing tile void, insulate as code requires, and terminate them properly at the top. For North Merrick’s typical 1950s ranches with straight internal flues, rigid sections sometimes work better. We’ll tell you which makes sense for your stack, and you’ll see the interior on camera before we start.
Liner Replacement
When the old clay tiles are cracked, offset, or showing gaps between sections, replacement is the only fix that restores a safe draft. In North Merrick, we often find spiral cracks from salt air spalling that have been opening for years. We extract the old liner where possible and drop in a properly sized stainless or HeatShield resurfacing system. Your flue doesn’t care how the fire looks. It cares how it breathes.
Partial Rebuild
North Merrick’s bay-adjacent humidity wrecks crowns and upper courses first. If the flue is below grade but the top five to ten courses are spalling, a partial rebuild with lime-based mortar gets the shell sound again without tearing down the whole stack. We rebuild from the roofline up, pour a proper crown with a drip edge, and flash it correctly as part of our Chimney Cap & Crown in North Merrick work. Then we run the camera through and show you the seam between old and new.
For full rebuilds, liner repair, and specialized Chimney Liner & Rebuild work, the same crew handles everything from demolition to final wash coat. No subcontracted bricklayers you’ll never see again.

Trusted Brands We Service in North Merrick
We install and service liner systems from DuraFlex, HeatShield, Gelco, and Famco, along with our Fireplace Services in North Merrick including Olympia Chimney caps and Copperfield components. Because we work these same towns every week, we stock common liner diameters and cap sizes on the truck, which saves North Merrick customers a second visit for parts. HeatShield’s resurfacing system has become the go-to for gas conversions here because it re-lines the existing flue without demolition, and we’ve put it into dozens of Nassau County chimneys since it hit the market.
Common Chimney Liner & Rebuild Problems We See in North Merrick Homes
- Oversized oil-era flues venting gas appliances. When a 1955 chimney built for an oil burner suddenly vents a 78% efficient gas furnace, the exhaust cools too fast. Condensation forms inside the flue and eats the clay tiles from the joint inward. This is the single most common issue in North Merrick’s post-war housing stock.
- Abandoned second flues hiding third-degree creosote. Dual-flue chimneys were standard on these Capes and split-levels, one for the fireplace, one for the furnace. When the furnace switched to gas or moved to a direct vent, the old oil flue sat sealed with a clay tile cap and a quarter-inch of creosote glaze from the final oil burn. Nobody looks at it until we run a camera. North Merrick has more of these than almost any town we work.
- Portland cement repointing from the 1980s and 90s. Somewhere along the line, a well-meaning homeowner or handyman patched the crown with hard Portland mix. In North Merrick’s salt-laden air, that hard patch traps bay moisture behind the brick face, and freeze-thaw spalling works the joint open from the inside. We often find brick faces popping off crowns that looked fine from the ground.
- Cracked flue tiles from decades of salt air. North Merrick sits two miles north of Merrick Bay and the Great South Bay, and the persistent salt humidity accelerates tile deterioration well beyond what inland towns see. Cracked tiles let carbon monoxide and flue gas migrate into the wall cavities before anyone sees a symptom.

FAQs - Chimney Liner & Rebuild in North Merrick
Yes, in nearly every case. Your 1950s chimney was sized for oil’s hotter exhaust. Gas exhaust is cooler, condenses inside that oversized flue, and breaks down the clay tile joints over time. The chimney can look fine from the outside while the interior is degrading. We’ll run a camera and show you exactly what’s there. If the liner is sound, we’ll tell you that too. Call (516) 963-1068 for a free estimate either way.
That white crust is efflorescence, salt and minerals being pushed out of the mortar as water gets in and tries to escape. In North Merrick, the salt-laden humidity off Merrick Bay accelerates this cycle because salt attracts and holds moisture against the masonry. If the crown was repointed with hard Portland cement at some point, the problem compounds, trapped water freezes and spalls the brick face. The fix is a lime-based repointing and a proper new crown, not another layer of hard patch.
Absolutely. The abandoned furnace flue is the one we find with cracked tiles, offset sections, or old creosote glaze from the final oil burn. It’s been sealed and ignored for decades. If you’re adding a liner to one flue, we always camera the other while we’re up there. North Merrick’s dual-flue chimneys hide more problems in the unused flue than the one people actually burn with.
Usually, yes. If the interior flue void is intact and the masonry shell is structurally sound, we can drop a stainless liner through the existing cavity without touching the brick. We only recommend a partial or full rebuild when the shell itself is spalling, the crown has failed, or the flue is off center beyond what a flexible liner can navigate safely. You’ll see the camera scan before we make that call, and the price difference is laid out plain.
A Level 2 camera scan is the answer. We drop a camera down the flue and show you the live footage on a tablet in your driveway. Cracked tiles, gaps, offset sections, and hidden creosote are all visible in real time. Nothing gets touched until you’ve seen what we see. In North Merrick, where salt air and old oil-era flues are the norm, this is the single most useful diagnostic we do. Call (516) 963-1068 and we’ll schedule a scan.
