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.
Trusted Chimney Repair for Brentwood Homeowners
Chimney repair in Brentwood, NY typically costs between $300 and $3,500, depending on whether you need mortar repointing, flashing replacement, a partial rebuild, or a full crown reconstruction. Most repairs that don’t require major rebuilding can be completed in a single visit, and we’ll always show you camera footage of the problem before any work begins. If you suspect a chimney issue, don’t wait - call (934) 935-3847 for a free estimate from Wendell Pike and his crew at Top Hat Chimney.
Wendell founded Top Hat Chimney back in 1999, and in the decades since, he has worked on chimneys throughout Brentwood, Central Islip, Hauppauge, and the surrounding Suffolk County communities. That’s over 29 years of rebuilding crowns, repointing mortar joints, and replacing flashing on houses that were built the same year your parents moved in. His name is on the truck, his license number is published, and the 90-Day Done Right Promise comes with every job in writing. If something isn’t right, one call brings him back at no charge. We answer the phone live, around the clock - and it’s often Wendell himself on the other end.
Your flue doesn’t care how the fire looks. It cares how it breathes. A chimney that has been ignored for years may look fine from the driveway, but water, freeze-thaw cycles, and creosote do their work quietly. We will tell you plainly what needs fixing and what can wait - and show you the proof on camera before we recommend a single repair.
What Our Chimney Repair Service Includes
A chimney is a system, not a single component. The bricks, the mortar between them, the flashing at the roofline, the crown on top, and the waterproofing that protects it all - each piece fails on its own schedule, and each failure has a different fix. Here is what we handle, and how we approach each job.
Mortar Repointing
Mortar is the glue that holds your chimney together, and it wears out long before the bricks do. Over years of Long Island weather - rain, snow, and the freeze-thaw cycles that hit Brentwood every winter - the mortar softens, crumbles, and opens gaps that let water into the structure. Wendell and his crew rake out the damaged joints to a proper depth and pack in fresh mortar that matches the original color and texture. Mortar repointing done right restores the structural strength of the chimney and stops water from getting inside the brickwork. We don’t just fill the gaps; we remove the bad mortar first, and that is the difference between a repair that lasts decades and one that fails in two years.

Spalling Brick Repair
Spalling happens when water soaks into the bricks, freezes, and forces the brick face to pop off. You’ll see flakes of brick on the ground near the chimney, or chunks missing from the chimney surface. Once spalling starts, it doesn’t stop on its own - every winter makes it worse. Depending on how far the damage has gone, we repair it by replacing the affected bricks or cutting out the damaged faces and applying a matching brick veneer. On houses throughout Brentwood and Bay Shore, we regularly see spalling that started with a small crack and grew into a structural problem over five or six seasons. The fix is straightforward when it’s caught early.

Chimney Waterproofing
Brick is porous. It soaks up water like a sponge, and that water does damage in two directions: inside the flue and inside the brick itself. We apply a vapor-permeable waterproofing treatment that blocks liquid water while letting moisture escape from inside the masonry. That last part matters - sealing a chimney with the wrong product traps water inside and accelerates damage. We use waterproofing materials designed specifically for chimneys, not generic sealers off the shelf at the home center. After waterproofing, the chimney sheds rain instead of absorbing it, which extends the life of the mortar, the bricks, and the liner.

Flashing Repair
Flashing is the metal seam where your chimney meets the roof, and it’s the most common source of chimney-related leaks in Brentwood. Roofers often do a marginal job on chimney flashing, and decades of expanding and contracting with the seasons pull the seals loose. The leak you’re seeing on your ceiling may have nothing to do with the chimney interior - it’s the flashing. Wendell and his crew replace old flashing with proper step flashing and counter-flashing, integrating it correctly with the roof so water is directed away from the chimney. We’ve fixed thousands of flashing leaks over the years, and we’ll show you exactly what was wrong before we fix it.

Chimney Rebuilding
When the top few feet of a chimney have too much damage for spot repairs - brick faces missing, mortar joints gone, the structure leaning or visibly cracked - a partial rebuild is the honest fix. We tear down the damaged section to a solid base and rebuild it with new brick or salvaged matching brick, then finish with a proper crown. On older Brentwood homes, we often match the existing brick closely enough that the repair is invisible from the yard. A full rebuild from the roofline up is a bigger job, but when the alternative is a chimney that crumbles into the house, it’s the right call. We’ll never recommend a rebuild where a smaller repair will do.

Tuckpointing
Tuckpointing is often confused with repointing, but it’s a separate technique: after the joints are cleaned and refilled, a thin contrasting line is applied to make the mortar joints look uniform and crisp. On older homes where the mortar has been patched many times with mismatched colors, tuckpointing restores a clean, even look across the whole chimney. We do this most often on Brentwood houses with decorative brickwork that’s visible from the street. The structural repair underneath is the same careful joint work; tuckpointing adds the finished appearance. When finished, the chimney looks like it did when the house was built.

Brands We Service for Chimney Repair
We install and service chimney liners and components from the brands that have proven reliable over the long haul. DuraFlex liners are a common sight around Brentwood - they’re flexible stainless steel, designed to snake down older flues that were built with terra cotta tiles. We’ve installed and repaired hundreds of them, and when one has failed, it’s usually because of improper installation by someone else. We know the product well enough to fix it right the first time.
HeatShield is our go-to for restoring damaged clay tile liners without a full liner replacement. The HeatShield system recoats the inside of the existing flue with a ceramic material that seals cracks and restores safety. We’re certified in the HeatShield process and can tell you within minutes whether your flue is a candidate. Famco and Copperfield produce the caps, dampers, and chase covers we install on a regular basis, and we stock their common sizes on the truck. Whether your chimney has one of these systems or something else entirely, Wendell and his crew can assess it, repair it, and stand behind the work.
Signs You Need Chimney Repair Right Now
- Water stains on the ceiling or walls near the chimney. This usually means flashing failure or cracks in the crown. Water that gets through the roof line doesn’t just cause cosmetic damage - it rots the framing around the chimney and can lead to mold inside wall cavities. The longer it runs, the more expensive the fix becomes.
- Chunks of brick or mortar on the ground or in the gutter. Spalling brick means water has already penetrated the masonry. Once the brick faces start popping, you’re not looking at a cosmetic issue - the structural integrity of the chimney is compromised, and every freeze-thaw cycle makes it worse.
- A rusted or missing chimney cap. The cap keeps rain, animals, and debris out of the flue. Without one, water pours directly into the chimney during every rainstorm, accelerating liner damage and rusting out the damper. This is one of the cheapest repairs we do, and the one that saves the most money down the road.
- White staining (efflorescence) on the chimney exterior. That white powdery deposit is salt being pulled out of the brick by water traveling through the masonry. It means the chimney is saturated. Efflorescence is a warning sign that the waterproofing has failed or was never there in the first place.
- Smoke backing up into the house. A blocked flue, a collapsed liner, or a chimney that’s no longer drafting properly can push carbon monoxide into your living space. If you notice smoke lingering in the room or a musty smell from the fireplace, stop using it and call us. Carbon monoxide has no odor - the smoke you see is the messenger.
Our Chimney Repair Process - Step by Step
- 1
Call and talk to a real person. When you call (934) 935-3847, someone answers - day or night, and often it’s Wendell himself. We’ll ask about what you’re seeing, schedule a visit, and give you a real arrival window. No call center, no voicemail box, no “press 1 for service.”
- 2
The inspection. Wendell or a member of his crew arrives in uniform, on time, and goes over the chimney from top to bottom. We look at the crown, the flashing, the mortar joints, the cap, and the interior of the flue. If we can’t see it clearly, we use a camera to get a look inside.
- 3
You see the footage, you get the verdict. We don’t ask you to take our word for it. We show you the camera images and explain in plain English what’s wrong, what needs fixing, and what can wait. The camera footage and a plain-English verdict - every time, no exceptions. If a liner doesn’t need replacing, we’ll say so. If the flashing needs work, you’ll see the gap yourself.

The quote. Before any work starts, you get an upfront price in writing. The number you hear on the phone is the number on the invoice. No changed prices at the door, no surprises. If you have a written estimate from anyone else, bring it to us for a free second opinion - we’ll tell you if it’s fair, and if it is, we’ll say that too.

How Much Does Chimney Repair Cost in Brentwood?
Here’s what you can expect to pay for common chimney repairs in the Brentwood area:
| Repair Type | Typical Cost Range (Brentwood, NY) |
|---|---|
| Chimney cap replacement | $180 - $450 |
| Flashing repair or replacement | $400 - $1,100 |
| Mortar repointing (partial) | $500 - $1,500 |
| Spalling brick repair (per section) | $350 - $900 |
| Chimney waterproofing | $300 - $700 |
| Crown repair or rebuild | $500 - $1,800 |
| Partial chimney rebuild (above roofline) | $1,500 - $3,500 |
| HeatShield liner restoration | $1,200 - $2,800 |
What drives the price is access. A one-story ranch in Brentwood with a gentle roof pitch is a lot easier to work on than a three-story colonial with a steep pitch in nearby Islip Terrace. The condition of the existing chimney matters too - a chimney that has been maintained will need less prep work than one that’s been ignored for twenty years. The number of flues, the height off the ground, and the type of materials all factor in. We don’t charge a trip fee inside our service county, and our quotes are free. You get the exact price before any tool comes off the truck. Call (934) 935-3847 and we’ll come take a look.

Frequently Asked Questions - Chimney Repair in Brentwood
Chimney repair is any work that restores the structural or functional integrity of your chimney - repointing mortar joints, replacing damaged bricks, fixing flashing, rebuilding crowns, restoring liners, or waterproofing the masonry. It’s not the same as chimney cleaning, which removes creosote and soot. A chimney can be clean but still unsafe if the structure is failing. We do both, and we’ll tell you which one you actually need.
Most common repairs - flashing, repointing, cap replacement, waterproofing - are completed in a single visit of two to five hours. A partial rebuild may take a full day or two depending on the weather and the extent of the damage. Liner restoration with HeatShield typically takes one visit, with a curing period before you can burn again. We’ll give you a clear timeline before we start, and we’ll call if anything changes.
Chimney repair in Brentwood typically runs from $300 for a simple cap replacement to $3,500 for a partial rebuild above the roofline. The average job falls somewhere between $500 and $1,500.
