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.

Call (516) 963-1068 for a straight answer and an honest quote before the next freeze-thaw cycle does more damage.
We’ve worked enough chimneys in West Hempstead to know what the salt air off the South Shore bays does to mortar, and what sixty-five years of freeze-thaw cycling does to a terra cotta liner.

Why Top Hat Chimney Is West Hempstead’s Preferred Chimney Repair Company
Wendell Pike started Top Hat Chimney in 1999, and he still answers the phone at midnight when a homeowner in West Hempstead smells something odd behind the wall. That’s not marketing. That’s how an owner-operated shop works. Your call is picked up by a live person, twenty-four hours a day, and it may well be Wendell himself on the other end.
People in West Hempstead hire us because we put the price in writing before a single tool comes off the truck. The number you hear on the phone is the number on the invoice. We also stamp every completed job with our 90-Day Done Right Promise: if it’s not right, one call brings the crew back, no charge. That promise matters on a shared stack in an attached Cape Cod, where someone else’s retrofit can cause problems inside your flue.
West Hempstead homeowners have been burned by national outfits that quote one price on the phone and another at the door. That doesn’t happen with an owner-operator who lives in the trade, publishes his name and license number, and runs into you again on Saturday at the grocery store.
Our Chimney Repair Services in West Hempstead
Mortar Repointing
West Hempstead’s brick chimneys, built during the 1945-1962 suburban boom, are now 65 to 80 years old. The mortar joints are the first thing to fail. Salt-laden air from the Great South Bay accelerates erosion beyond what inland Nassau County neighborhoods see, and once a joint opens up, water gets behind the brick and the freeze-thaw cycle starts working. A typical repointing job on a West Hempstead chimney runs $500 to $1,100, depending on how many courses need work. We grind out the old mortar to a proper depth and pack in fresh compound that breathes with the brick instead of trapping moisture.
Spalling Brick Repair
Spalling is what happens when water saturates a brick face, freezes, and pops it off in sheets. We see it constantly on West Hempstead chimneys where tight eaves and close lot lines made the crown hard to reach for years. A homeowner ignores a cracked crown, winter does its work, and spring reveals missing brick faces. Repairing spalled sections costs $75 to $150 per brick face plus prep, and most West Hempstead jobs land between $600 and $1,400. We match the brick as closely as the original 1950s color allows.
Chimney Waterproofing
Honest talk: waterproofing is the single best dollar you can spend on an older West Hempstead chimney. Once we’ve repaired joints and bricks, we apply a siloxane-based repellent that lets the masonry breathe while blocking water. A typical application runs $350 to $600 for a single-flue chimney. It doesn’t fix damage that’s already there, and a good sweep will tell you that before selling it to you. But applied after a proper repair, it adds years to the work.
Flashing Repair
Flashing is where the chimney meets the roof, and on West Hempstead’s original 1950s homes, it’s usually the first thing to leak. The metal corrodes, the sealant dries out, and water follows the brick down into the attic. Repairing or replacing flashing runs $450 to $950 on most West Hempstead properties. On rowhouse-style and attached Cape Cods, we also check the shared stack, because a neighbor’s flashing leak can track into your side of the wall.

Trusted Brands We Service in West Hempstead
We install and service liners from DuraFlex and Olympia Chimney, plus caps and crowns from Famco and Copperfield. Because we’re local, we stock common parts for West Hempstead’s older single- and double-flue chimneys, so you’re not waiting a week on a shipped cap or a liner section. If you have an existing system from one of these brands, we’ll match it; if you don’t, we’ll recommend the right product for your flue and your budget, and we’ll show you the invoice line before the work starts.
Common Chimney Repair Problems We See in West Hempstead Homes
- Shared-flue cross-contamination. In attached Cape Cods and small colonials, a neighbor’s high-efficiency gas appliance may vent into a common stack. That can drive acidic condensate through your clay tiles without you ever knowing it’s happening.
- Oil-to-gas liner rot. West Hempstead’s post-WWII chimneys were sized for oil-burner draft. Venting a modern 80-95% efficiency gas boiler through that oversized flue runs too cool, and the result is internal corrosion that a visual sweep alone won’t catch.
- Freeze-thaw crown cracking. Winter temperatures around West Hempstead oscillate around freezing more than they stay deeply cold. That repeated expansion and contraction opens hairline cracks in crowns, and within a few seasons the brick faces start popping.
- White sulfurous staining. This is the tell on a gas-converted flue. When we see it in a West Hempstead inspection, it almost always means acidic condensate has been eating at the liner. First-degree creosote is a brush job. This is not.

FAQs - Chimney Repair in West Hempstead
We just converted from oil to gas heat in West Hempstead-do we need a chimney liner inspection before winter?
Yes. Your chimney was originally sized for oil-burner draft, and a modern gas boiler vents cooler exhaust. That cool exhaust produces acidic condensate inside your clay tile liner, and the damage often shows up as white sulfurous staining before the tiles crack enough to be dangerous. A Level 2 camera inspection runs a few hundred dollars and tells you exactly what’s happening inside the flue. Call (516) 963-1068 and we’ll walk you through what the footage shows.
My neighbor in West Hempstead vents their gas boiler into the same chimney stack as mine-is that safe?
Not necessarily. Shared stacks in West Hempstead’s attached Cape Cods are common, but the flue was never designed to carry exhaust from two different appliances of different eras. If their retrofit gas furnace vents into the same flue as your system, you can get acidic condensate from their side eating at your liner. We’ve repaired exactly this condition in the Lakeview section, where a reline on the customer’s side and a proper crown cap fixed the immediate risk. Get a Level 2 inspection before the next heating season.
Why does my West Hempstead chimney crown crack every few years even after repointing?
Because West Hempstead winters hover around freezing more than they stay deeply cold, and the salt air off the South Shore keeps the moisture load high. Every cycle opens hairline cracks a little more, and repointing alone won’t stop it. The crown needs sealed properly, and in most cases the chimney needs waterproofing after the repair. That combination is what actually breaks the cycle.
How do I know if the white staining inside my West Hempstead chimney is creosote or acid damage?
Creosote is dark, tarry, and flammable. The white sulfurous staining we see routinely in West Hempstead is mineral residue left by acidic condensate, and it means your clay tiles are dissolving from the inside. If you see it, do not wait for the chimney to fail. A camera inspection confirms which one you’re dealing with, and we’ll show you the footage. Call (516) 963-1068 for an estimate.
Can you repair my West Hempstead chimney flashing without replacing the whole roof?
Almost always, yes. We work around the existing roof, cutting back only as far as needed to install new flashing and sealant, so you’re not paying for reroofing. Most West Hempstead flashing repairs run $450 to $950. If the roof is already failing around the chimney, we’ll tell you that plainly and tell you exactly what can wait.
