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.

AfterTrusted Chimney Repair for Hempstead Homeowners
Chimney repair in Hempstead usually means one of three things: water is getting in where it shouldn’t, the mortar joints have started to crumble, or the flue itself has a crack or gap that cannot wait. We’ve been fixing all three since 1999, and most repairs we handle are done within a week of your call. If you can see missing mortar, a rusted damper, or water staining on the ceiling near the chimney, call Wendell at (516) 963-1068 and he’ll give you a straight answer before he ever sets foot on your roof.
Hempstead is a village of older homes, and older homes have older chimneys. Brick and mortar take a beating from Long Island winters, salt air, and the freeze-thaw cycle that works joints loose a little more each year. We’ve repaired chimneys on Clinton Street, around Kennedy Park, and through the neighborhoods off Peninsula Boulevard. Wendell lives in the area and has worked these rooftops for over 29 years offering Hempstead Chimney Repair. When you call Top Hat Chimney, you get his inspection, his price, and his name on the work.
What Our Chimney Repair Service Includes
Chimney repair is not one job. It’s a range of work, and the honest part is knowing which one you actually need. Here is what we do, how it works, and the point where we’ll tell you the work can wait. From our home base in Hempstead, we handle all six of these repairs regularly.
Mortar Repointing
Mortar Repointing means removing the old, crumbling mortar between bricks and packing in fresh mortar that matches the color and hardness of the original. Hempstead chimneys from the 1920s through the 1960s often have lime-based mortar that modern Portland cement will actually damage because it’s too hard and traps moisture. We match the original mix, not just the color. You need repointing when mortar joints are eroded more than a quarter inch deep, which lets water sit in the joint and pop the brick faces during winter freezes.
Spalling Brick Repair
Spalling Brick Repair addresses when the face of a brick cracks off in flakes or sheets, usually because water got inside the brick and froze. You’ll see brick chips on the roof or in the gutter, and the exposed inner brick looks rough and orange. On Long Island, spalling is common on chimneys with cracked crowns or missing caps, because those let water directly into the masonry. We replace the damaged brick with a match for size, color, and age, then fix whatever let the water in, so the repair lasts.
Chimney Waterproofing
Waterproofing is a vapor-permeable sealer brushed or sprayed onto the brick after repairs are done. The key word is permeable: it keeps rain out while letting water vapor inside the brick escape, which is critical in Nassau County humidity. A good waterproofing job from Top Hat Chimney usually lasts eight to ten years. We apply it as a soak, not a thin coat, and only after the masonry is clean and dry.
Flashing Repair
Flashing is the metal that seals the joint where the chimney meets the roof, and it’s the most common leak point we find in Hempstead. If the flashing is lifted, rusted through, or patched with roofing tar instead of replaced, water runs down the chase and into your attic or second-floor ceiling. We cut out the old flashing, install new step and counter flashing, and seal it so it moves with the freeze-thaw cycle instead of fighting it. A roof leak near the chimney is flashing trouble until proven otherwise.
Chimney Rebuilding
When a chimney is leaning, has loose brick you can wiggle by hand, or has lost more than a third of its mortar, rebuilding is cheaper and safer than patching it repeatedly. We take the chimney down to the point of solid structure and rebuild it, often reusing good brick from the original stack. For partial rebuilds, which cover the section above the roofline, we brace the remaining structure first, then lay to the original footprint. Wendell will tell you plainly if a rebuild is needed, or if repointing will buy you five more years.
Tuckpointing
Tuckpointing, in the strict sense, is the finish work of using thin contrast lines in the mortar to create a crisp, uniform look. In everyday terms, it has come to mean the careful cosmetic matching of new mortar to old. For chimneys where appearance matters, like a face brick chimney on the front of a Hempstead colonial, we use tuckpointing techniques so the repair does not look like a patch. The joint lines stay straight, the color blends, and the work looks original.

Brands We Service for Chimney Repair
We work on all chimney systems, and we use familiar brands because parts availability matters when a liner or cap needs replacement. HeatShield is a ceramic resurfacing material we apply to flues with minor cracking, and we have been certified to install it for years. It is often the most affordable way to restore a flue without a full liner replacement.
Gelco chimney caps and chase covers are what we install on the majority of homes in Hempstead because they handle salt air and rust better than galvanized. Olympia Chimney makes the stainless liners and connector pipes we use when a liner is truly beyond repair and needs to be replaced. If you have a different brand, whether it’s a Famco termination or an older system from a previous owner, we still service it. The brand matters less than the condition of the masonry around it.
Signs You Need Chimney Repair Right Now
- Water staining on the ceiling or walls near the chimney. Water is following a gap somewhere, usually flashing or a cracked crown, and finding your drywall. Left alone, it rots framing and feeds mold inside the chase. In Hempstead’s older homes, this is the most common first sign we hear about.
- Mortar that flakes when you touch it. Run a finger along a joint, if the mortar crumbles like sand, it has lost its binding and is no longer keeping water out. This progresses to spalling and loose brick. Catching it early means repointing, not a rebuild.
- A chimney that leans or has visible brick displacement. Masonry does not shift on its own. Movement means water has damaged the core or the footing has settled. A leaning chimney above a bedroom is not something to watch over the winter.
- Rust on the damper or firebox interior. Rust means water is entering the flue regularly and sitting. The damper is the easiest place to see it. Rust there suggests a failed cap, damaged crown, or open mortar joints higher up.
- You smell smoke or damp, soot smell even when there is no fire. That odor means the flue is not drafting and indoor air is pulling down the chimney instead. It can point to cracks, blockages, or a structure that is no longer sealed. A sweep and inspection will find the cause.
Our Chimney Repair Process - Step by Step
- 1
You call, Wendell answers. Not a call center. You’ll describe what you’re seeing, and Wendell will ask the questions that matter: when it started, what the staining looks like, whether you burn fires or just have a furnace flue. If the issue sounds urgent, he will prioritize your visit.
- 2
On-site inspection with camera. Wendell runs a camera up the flue, every time. You see the footage. If the flue has a crack, a gap, or a stage-three creosote glaze, you will see it with your own eyes before anyone recommends work.
- 3
A plain-English verdict and a fixed price. You get a written quote before a single tool comes off the truck. If no repair is needed, Wendell will tell you that. If a repair can wait a year, he’ll say so and you can hold him to that.
- 4
The repair, done with matched materials. Work is done by Wendell or a background-checked member of his crew in uniform, using mortar, brick, flashing, and sealers matched to your chimney’s age and condition. Work areas are protected, and debris is hauled away.
- 5
The 90-Day Done Right Promise. Every job is backed in writing. If anything about the work isn’t right within 90 days, one call brings Wendell back at no charge. Most repairs never call, but the promise is on every invoice we print.
How Much Does Chimney Repair Cost in Hempstead?
A typical chimney repair in Hempstead runs between $380 and $2,600 depending on the scope, so how much Chimney Repair costs varies with the work needed. Flashing repair is usually the least expensive, starting around $380 for a simple one-side replacement. Mortar repointing on a standard single-flue chimney typically runs $650 to $1,200. Chimney waterproofing runs $350 to $550. A partial rebuild above the roofline commonly falls between $1,800 and $3,200, and a full rebuild can exceed $5,000 depending on height and access. None of these are quotes, but they reflect what we have charged across Hempstead, Westbury, and Uniondale in the last year.
What changes the price? Height and roof pitch, because a second-story chimney on a steep roof requires different staging than a short chimney off a garage. Access matters too: if we can back a ladder truck to the house and work from the roof, it costs less than setting up scaffold in a narrow side yard. The condition of the footings and the interior flue can change the scope once we open things up. To avoid overpaying, never accept a repair quote from someone who has not put a camera up the flue. Get the line items in writing. And remember, we offer $40 off any repair over $200, a free second opinion on any written estimate, and no trip charge for calls inside our service county. Call (516) 963-1068 for a free estimate that comes with a printed number before any work begins.

Frequently Asked Questions - Chimney Repair in Hempstead
Chimney repair is any structural or waterproofing work that restores the masonry, liner, cap, crown, or flashing of a chimney so it safely vents smoke and gases and keeps water out of your house. It ranges from repointing small areas of mortar to tearing down and rebuilding the stack above the roofline. In Hempstead, the repair we do most often is flashing and crown work, because water intrusion is the root of nearly every chimney problem we see.
Flashing repair and crown sealing are typically done in a single visit, usually four to six hours. Repointing a full chimney takes a day to a day and a half. A partial chimney rebuild above the roofline takes two to four working days depending on height and weather. We’ll give you a time frame in the quote, and Wendell keeps his crew on the job until it is finished.
Plan on $380 to $2,600 for most repairs, with full rebuilds above that. The square footage of masonry, roof access, and how deep the damage goes all move the final number. We quote the price before starting, and that is the price on the invoice. Call (516) 963-1068 and get a free estimate with no trip charge inside our Hempstead service area.
Yes. We’re certified to apply HeatShield ceramic flue resurfacing, and we install it regularly in Hempstead homes where a clay liner has minor cracking but is otherwise sound. We also install and repair Gelco caps, Olympia Chimney liners, and Terminox stainless systems. The system you have will not be a problem; the condition of the flue and the masonry decides the repair.
If water is actively pouring into your house around the chimney, call (516) 963-1068 any hour. Wendell or a live person from Top Hat will answer and talk you through the immediate step: often tarping or a temporary cap until we can get on the roof safely. For dangerous conditions like a leaning chimney, we will prioritize your visit. We do not run a voicemail box or a national dispatch service, so when you call at midnight, you get a person.
Every repair from Top Hat Chimney carries the 90-Day Done Right Promise in writing. If the work we did fails to perform within 90 days, we return and correct it at no charge. For materials like liners and caps, the manufacturer’s warranty applies, and we register that warranty for you when the job is complete. Wendell puts his name on every invoice because he knows he’ll see you again in town.
Clear the area around the fireplace inside, and move any furniture you don’t want dust near. Outside, make sure we can reach the roof: move any parked cars, and unlock gates for ladder access. Keep pets inside on the day of the visit. We’ll lay drop cloths inside and clean up the work area before we leave.
