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.

Chimney repair in Long Island typically costs $350 to $3,500 depending on what’s wrong, and most common fixes like flashing repair or mortar repointing can be completed in a single visit. The job is identifying the actual problem, not selling you a rebuild you don’t need. Wendell Pike has been climbing Long Island rooftops since 1999, and he’ll show you the camera footage before he recommends a single brick be touched. Call (516) 968-5380 and you’ll get a live person, not a call center.

Top Hat Chimney has served the same Long Island communities for over 29 years, and Wendell puts his name and license number on every job. If it’s not done right, the 90-Day Done Right Promise means one call brings him back. No fine print, no runaround.

What Our Chimney Repair Service Includes
Mortar Repointing
Mortar Repointing is the process of grinding out deteriorated mortar joints and packing fresh mortar in. When Long Island freeze-thaw cycles break down the joints between bricks, water seeps in and the damage compounds year after year. We match the new mortar to your existing brick color and joint profile, and we do it by hand, not with an angle grinder set to speed. Repointing runs roughly $15 to $30 per square foot of wall area, and it’s the single best dollar-for-dollar repair for extending a chimney’s life.
Spalling Brick Repair
Spalling Brick Repair is what happens when water gets inside the brick and freezes, popping the face off. It’s common near the top of Long Island chimneys, especially on north-facing exposures in Dix Hills and Smithtown where the thaw is slower. We replace compromised bricks with new ones rated for exterior exposure and treat the area so the face doesn’t peel again. Left alone, spalling moves deeper and turns into structural repair instead of cosmetic patching.
Chimney Waterproofing
Waterproofing is a vapor-permeable treatment that lets moisture escape but keeps rain and snow out. We apply it to brick, mortar, and crown after any repointing or rebuild so your future repair costs actually shrink. Most Long Island chimneys that have never been waterproofed show measurable water absorption within ten years of construction, and we see it constantly in Commack and Levittown homes built in the 1950s and 60s. It’s a modest add-on that pays for itself the first time you skip a leak repair.
Flashing Repair
Flashing is the metal seam where your chimney meets the roofline, and it’s the most common source of chimney leaks in Long Island. We remove failed caulking and corroded metal, then install new flashing with staggered laps and proper counter-flashing rather than relying on a tube of caulk. Our flashing repairs come with a written expectation of how long the fix should last, and we stand behind it with the 90-Day Done Right Promise.
Chimney Rebuilding
Rebuilding is reserved for chimneys where the top has deteriorated past the point of repointing or brick replacement. We rebuild from the roofline up or from the crown down, depending on what the camera shows, and we reuse sound brick wherever possible to keep the price fair. A partial rebuild on Long Island typically runs $2,000 to $5,000, and we’ll tell you plainly if the rest of the chimney has five good years left so you don’t pay for work you don’t need yet.
Tuckpointing
Tuckpointing is a more detailed version of repointing, used when the mortar joints are narrow and you want the repair to disappear into the existing brickwork. It’s common on older homes in Rockville Centre and Freeport where the original mortar was lime-based and modern Portland cement would damage the brick. We match the mortar density to the age of the home and cut the joints by hand where needed, so the repair looks original and handles like original.

Brands We Service for Chimney Repair
We’ve installed and serviced Copperfield chimney caps and dampers on hundreds of Long Island homes. Copperfield’s top-mount dampers are one of the more reliable pieces of hardware made, but the bracket work and chase-top fitment is where a lot of installers cut corners. We stock Copperfield OEM parts and we set every damper and cap with the same attention we’d give a repair on Wendell’s own chimney.
For liner work, we use DuraFlex and HeatShield systems because they’ve both held up well in our experience. DuraFlex flexible stainless liners give us a clean, code-compliant install in chimneys with offset flues, and HeatShield’s cerfractory liner repair can sometimes save a chimney that would otherwise need a full relining. We’ve also installed Gelco caps and chase covers for years and can tell you the difference between a Gelco stainless top and a cheap galvanized one after the first Nor’easter. Whether you have any of these brands or something else entirely, the repair process is the same: inspect, show you the footage, explain the options, and let you decide.
Signs You Need Chimney Repair Right Now
- Water in the firebox or on the hearth. A chimney that leaks during rain usually points to failed flashing or a cracked crown. In Long Island’s freeze-thaw climate, that small drip becomes a spalled brick and a bigger bill by spring.
- White staining on the exterior brick. Efflorescence means water is moving through the masonry and leaving mineral salts behind. It won’t brush off permanently until the water entry is stopped, and it’s one of the earliest signs of waterproofing failure.
- Crumbling mortar joints you can pick with a finger. When the mortar fails between bricks, the chimney loses its ability to shed water and withstand wind. Catch it at the repointing stage and you’re looking at hundreds, not thousands.
- Flakes of brick on the roof or in the yard. Spalled brick faces are the chimney literally shedding its protective surface. Once brick face pops, moisture penetrates the softer core and decay accelerates fast.
- A musty or smoky smell when the fireplace is not in use. That’s usually a drafting issue tied to a blocked flue, a failed damper, or negative air pressure. It’s also a carbon monoxide signal when the chimney is connected to a furnace or boiler, so don’t sleep on it.

How Much Does Chimney Repair Cost in Long Island?
A flashing repair in Long Island typically runs $350 to $900 depending on roof pitch and the condition of the surrounding shingles. Mortar repointing averages $15 to $30 per square foot, and most residential chimneys fall in the $800 to $2,500 range for full repointing. Chimney waterproofing runs $250 to $600 as a standalone service, less when it’s paired with repointing. A partial rebuild from the roofline up starts around $2,000 and can reach $5,000 or more if the damage extends below the roofline. Spalling brick replacement runs $40 to $80 per brick depending on access and matching.
What affects the price: roof access, chimney height, the condition of what’s underneath the surface, and whether we’re matching old brick or standard modular sizes. How to avoid overpaying: get a camera inspection before any repair recommendation, and ask to see the footage. We show it on every job, no exceptions. A written estimate from us includes exactly what we’ll do, what it costs, and what the 90-Day Done Right Promise covers. Call (516) 968-5380 and we’ll come out, look at the chimney, and tell you the truth about how much Chimney Repair costs. If it can wait, we’ll tell you it can wait.

Frequently Asked Questions - Chimney Repair in Long Island
Chimney repair is any work that restores the structural or functional integrity of the chimney system: repointing mortar joints, replacing spalled bricks, repairing or replacing flashing, waterproofing the masonry, fixing crowns and caps, and rebuilding the top section when damage is too far gone. On Long Island, water intrusion from freeze-thaw cycles is the root cause of most repairs. We diagnose the exact problem with a camera and fix what needs fixing, not what a sales script tells us to sell.
Flashing repair, crown patching, and small repointing jobs can be done in a single visit, usually four to six hours. Full repointing of a standard chimney takes a full day, and a partial rebuild runs two to three days depending on weather. We’ll give you a clear schedule before we begin and call if anything changes. Call (516) 968-5380 and we can often give you a same-week appointment.
Most repairs cost between $350 and $5,000, with flashing repairs on the low end and partial rebuilds on the high end. The average repair we do falls in the $800 to $2,500 range. We give you an exact written estimate before work starts, and the number on the paper is the number you pay. We also offer $40 off any repair over $200, and a 10% discount for seniors and veterans.
Yes, we install and service Copperfield dampers and caps, DuraFlex liners, HeatShield cerfractory repairs, and Gelco chase covers and caps on Long Island chimneys.

The same camera inspection and plain-English verdict applies no matter what’s on your chimney.
We answer the phone around the clock, so if you’ve got water pouring into the house or a visible structural issue, call us at (516) 968-5380 and we’ll talk you through what’s happening. We’ll schedule a temporary protection or a full repair as quickly as the weather allows. For active chimney fires, call 911 first. For smoke backing up or a suspected carbon monoxide issue, get everyone out and call your gas company or the fire department before you call us.
Every completed job is backed by the 90-Day Done Right Promise in writing. If the work is not done right, one call brings Wendell back at no additional cost. Some products we install carry their own manufacturer warranties, and we’ll explain what’s covered and for how long in plain English before you pay a dollar.
Clear the area around the fireplace if we’ll be working inside, and move any cars or yard equipment from the side of the house where the chimney is. We’ll set up drop cloths and clean up after ourselves. You don’t need to empty the fireplace, but keep kids and pets away from the work area while we’re on site. That’s it. We’ll handle the rest.
