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 Repair Across Hempstead
Chimney repair in Hempstead usually means one of three things: repointing mortar joints that salt air has eaten, rebuilding spalled brick at the crown, or relining a flue that was sized for an oil furnace and now vents a gas one. Wendell Pike and his crew at Top Hat Chimney have been doing this work since 1999, and we answer our own phone. Call (516) 968-5380 for a straight answer and a free estimate, no trip charge inside the county.
Why Top Hat Chimney Is Hempstead’s Preferred Chimney Repair Company
Nobody in Hempstead wants a chimney company that quotes one number on the phone and another at the door. We don’t do that. The price you hear on the phone is the price on the invoice, and it comes before a single tool comes off the truck. Wendell puts his name on the work because he runs into you again at the supermarket on Saturday. Ask anyone on your street. If they’ve had chimney work done around here, there’s a good chance they know the name.
Every job we finish, from a small flashing repair near the Hofstra campus to a full chimney rebuild off Peninsula Boulevard, carries the 90-Day Done Right Promise in writing. If it’s not right, one call brings Wendell back. That’s it. We also publish our license number and answer calls around the clock with a live person, not a call center. When you call about chimney repair in Hempstead, you may well get Wendell himself.
Our Chimney Repair Services in Hempstead
Mortar Repointing
In Hempstead, the mortar joints on chimneys built between 1945 and 1965 are original. That means raked joints, often struck thin during the postwar building boom, now open to rain and salt spray. Repointing in Hempstead typically runs $350-$800 for a standard single-flue chimney, depending on how many courses are deteriorated. We cut out loose mortar and pack fresh mortar that breathes with the brick. Replacing whole bricks because mortar failed is far more expensive.
Spalling Brick Repair
Spalling is what happens when water gets behind the brick face and freezes. Hempstead’s position eight to ten miles from Jones Beach means the freeze-thaw cycle arrives with salt-laden Atlantic moisture, and that combination pops brick faces off chimneys faster than inland towns. Repairing spalled brick on a typical Hempstead chimney runs $250-$700 when caught early. If it’s advanced, a partial or full chimney rebuild may be the honest call, and we’ll show you camera footage before recommending it.
Chimney Waterproofing
Waterproofing is exactly what it sounds like, but it doesn’t seal moisture in, it lets the masonry breathe while keeping rain and salt out. On Hempstead’s post-WWII Cape Cods and colonials, original chimneys were rarely built with a proper overhang or drip edge at the crown. Nor’easter-driven rain gets behind the brick. A chimney waterproofing treatment in Hempstead runs $300-$600 for an average single-family home, and it’s the cheapest insurance against spalling you’ll find.
Flashing Repair
Flashing is the metal joint where chimney meets roof, and on 60-to-80-year-old Hempstead homes, it’s usually galvanized steel that has rusted through or pulled away. Water follows the gap straight into the attic or chase. Flashing repair in Hempstead typically runs $300-$650 when we’re reworking the base flashing and counterflashing. We use heavier-gauge aluminum or copper where the homeowner wants it, and we don’t caulk over rot and call it fixed.

Common Chimney Repair Problems We See in Hempstead Homes
- Oversized flues from oil-to-gas conversions: A 1950s Hempstead Cape Cod was built with a flue sized for No. 2 fuel oil, which burns hot and needs a big throat. When the boiler was swapped for an 80-90% efficiency gas furnace, the flue stayed oversized. Flue gases cool too fast, condense, and the resulting acidic condensate eats the clay tile from the inside. We see this weekly on camera inspections.
- Clay tile liners cracked by age and weather: The original clay tiles in Hempstead’s postwar chimneys have been through 60 to 80 winters of freeze and thaw, plus decades of salt-laden air pushing in from the Atlantic. Cracks let creosote seep into the brick itself, which accelerates spalling and can leave a chimney leaning before anyone notices.
- Crowns without proper overhang or drip edges: Builders putting up thousands of homes quickly in the 1950s didn’t always form a proper crown. No overhang means water runs down the brick face instead of dripping away. In Hempstead, where nor’easters hammer the south shore, that’s a guaranteed path to spalled brick at the roofline.
- Flashing failure on steep Cape Cod rooflines: Cape Cods have a specific geometry, and the chimney-to-roof junction is unforgiving. When flashing rusts out or lifts, water tracks into the roof deck and the chimney chase. In Hempstead, we regularly find rot and staining inside the attic that the homeowner never saw from outside.

FAQs - Chimney Repair in Hempstead
If your home was built between 1945 and 1965 and the chimney has never been relined, it almost certainly still has the original clay tile flue. It matters because those flues were sized for No. 2 fuel oil, not the gas furnaces most of these homes now use. An oversized flue causes condensation that eats the clay from the inside, cracks it, and allows creosote into the brick. The only way to know is a camera inspection, which we include with every Chimney Repair job in Hempstead. Call (516) 968-5380 to schedule yours.
In most Hempstead homes, yes, we can repair the spalled brick and rebuild just the crown, if the damage is localized. If spalling is widespread, the brick has lost structural integrity, or the chimney is leaning, a full or partial rebuild is the honest call. We will show you the camera footage and the condition of the mortar joints before recommending anything. Nothing is recommended without evidence you can see.
Look for white staining or efflorescence on the exterior brick, flaking clay tile fragments in the fireplace or at the base of the flue, and a draft that seems weak even when the fire is burning well. These are signs the oversized flue has been condensing acidic flue gases for years. The first step is a camera scope, which shows exactly what the tiles look like inside. If relining is needed, we size a DuraFlex stainless liner to the gas appliance, not to the old oil furnace.
Repointing replaces deteriorated mortar joints with new mortar that matches the original strength and color. Tuckpointing is a cosmetic technique that uses a contrasting mortar line to make old brickwork look crisp. Hempstead chimneys need repointing far more often, because the salt-laden air and freeze-thaw cycles here erode actual mortar. If you hear a company suggest tuckpointing to fix structural joint failure, get a second opinion.
Once a year, even if you rarely burn. The salt air and nor’easter-driven moisture shorten the life of mortar, brick, flashing, and crowns on Hempstead homes regardless of how often you use the fireplace. Catching eroded joints or a cracked crown in year one costs a few hundred dollars. Waiting until water is streaming into the attic costs thousands. Call (516) 968-5380 to book an inspection.
