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 Commack Homeowners
Chimney repair in Commack usually costs between $195 and $1,400 depending on what’s wrong. A crumbling brick or a leaky flashing is a $200 to $400 fix. A full rebuild from the roofline up is the bigger job. Wendell Pike has been climbing Commack roofs since 1999 and will tell you which one you actually need. Not which one pads the invoice. Call (631) 502-3612 and a live person answers, whether it’s noon or 2 a.m. You’ll get a straight price before a single tool comes off the truck. And if it’s not done right, the 90-Day Done Right Promise puts it in writing that we come back and make it right, no charge.
What Our Chimney Repair Service Includes
Mortar Repointing
Mortar repointing is the process of scraping out decayed mortar joints and packing in fresh mortar. In Commack, freeze-thaw cycles work moisture into the joints every winter, and over a decade the mortar turns to sand. Wendell and his crew grind out the loose material to a proper depth and match the new mortar to your existing brick, both in strength and color. Done right, repointing stops water entry at the joints and keeps the chimney standing straight for another twenty years.
Spalling Brick Repair
Spalling is what happens when water soaks into the brick face, freezes, and pops the outer layer off. You’ll see brick chips on the ground or flaking red faces on the chimney itself. If you’re seeing spalled brick in Commack’s older neighborhoods near the Northern State, it’s usually advanced moisture damage, not a cosmetic issue. We cut out the damaged brick, set in matched replacements, and repoint the surrounding joints so the whole section works as one unit again.
Chimney Waterproofing
Chimney waterproofing is a vapor-permeable sealant applied to the masonry to keep water out while letting the chimney breathe. This is the job most Commack chimneys need and never get, and it’s why the same repairs come back every five years. We use commercial-grade masonry sealants that don’t trap moisture inside the brick. One application typically lasts a decade or more, and it’s the single best dollar you’ll spend on the chimney after the crown is sound.
Flashing Repair
Flashing is the sheet metal where the chimney meets the roof, and it’s the number one source of chimney leaks in Commack homes. We work with copper and aluminum flashing, and Wendell installs it the way it holds up through Long Island weather: overlapping layers, proper counter-flashing, and no caulk shortcuts. If your ceiling stains appear after heavy rain, the flashing is the first place we look. The camera goes in, and you see what we see.
Chimney Rebuilding
A chimney rebuild means taking the structure down to a sound point and laying new brick, block, or stone from there up. Sometimes that’s the top four feet above the roofline. Sometimes it’s the whole stack. In Commack, we see a lot of 1960s and 1970s chimneys where the freeze-thaw work has done too much damage for patch repairs. Wendell will show you the camera footage and give you a plain-English verdict on whether a rebuild is actually required or whether you’ve got years left in what’s there.
Tuckpointing
Tuckpointing is a finer version of repointing, focused on appearance as much as structure. Where standard repointing matches the joint to the brick, tuckpointing uses two tones of mortar to create crisp, clean lines on older masonry. For Commack homeowners with ornamental brickwork or chimneys visible from the street, it restores the original look while sealing out water. It’s detailed, slower work, and it’s exactly the kind of job that separates a careful mason from a rushed one.

Brands We Service for Chimney Repair
We install and repair chimney liners and components from DuraFlex and Olympia Chimney more than any other brands in the Commack area. DuraFlex liners are our go-to for gas and oil flue relining because the stainless steel handles the acidic condensate those appliances produce. Wendell has been working with their liner systems since they hit the market and sizes them to the exact flue dimensions, never a one-size-fits-most guess.
Olympia Chimney supplies the caps, dampers, and chase covers we see on a lot of Suffolk County homes, and yes, we stock their replacement parts. Famco is another name we work with regularly for caps and vents. Copperfield and HeatShield both make products we use for specific jobs: HeatShield for restoring flues without a full rebuild, Copperfield for quality flashing and waterproofing materials. Whether you’ve got one of these brands on your chimney or something the last homeowner installed thirty years ago, we can help.
Signs You Need Chimney Repair Right Now
- Water stains on the ceiling or walls near the fireplace. This means water is getting past the flashing, the crown, or the brick itself. Water inside the chimney chase doesn’t dry out on its own, it soaks into framing and drywall. The longer it runs, the bigger the repair bill gets.
- Crumbling mortar joints or missing pieces of brick. When the mortar goes, each brick carries more load than it was laid for, and the freeze-thaw cycle in Commack winters accelerates the decay. A joint that’s gone from a half-inch deep to a quarter-inch is a warning. A joint that’s gone entirely is a structural problem.
- A rusted firebox or damper that’s hard to move. Rust means water has been running down the flue. That water is also soaking into the masonry and the framing below. The damper problem might be the symptom you notice, but the chimney leak is the thing that needs fixing.
- White staining on the exterior brick. That white powder is efflorescence, which means water is moving through the brick and carrying salts out with it. It tells you the chimney is wet. The fix is waterproofing and proper drainage, not just brushing the white off.
- Debris falling into the fireplace between uses. Bits of mortar, brick chips, or flue tile in the firebox mean the chimney is actively degrading above you. The next time you light a fire, that loose material is what the smoke is passing through, and a cracked flue tile is a fire hazard. Have it looked at before the next burn.
Our Chimney Repair Process - Step by Step
- 1
Call and talk to a person. You call (631) 502-3612 and Wendell or someone on the crew picks up. You describe what you’re seeing, and we tell you honestly whether it sounds urgent or whether it can wait until the spring. If you’re inside our service county, there’s no trip charge.
- 2
We come out and inspect. Wendell arrives in a marked truck, in uniform, at the time he said. He goes up on the roof when it’s safe to do so, and he puts the camera down the flue. You see the footage on the spot. No vague warnings, no “trust me” explanations. The camera shows what’s there.
- 3
You get a plain-English verdict and a written price. Before any work begins, you know exactly what needs doing, why it needs doing, and what it costs. The number on the written estimate is the number on the invoice. No surprises at the door, no add-ons after the ladder goes up.
- 4
The repair happens with matched materials and real masonry work. For brick work, we match mortar color and brick size to your existing chimney so the repair doesn’t look like a patch. For liner and flashing work, we use the right metal and the right fastening method for a Long Island climate. The job is done the way Wendell would want it on his own house.
- 5
Cleanup and a final walk-through. We leave the roof and the hearth cleaner than we found them. Wendell walks you through what was done and what the chimney looks like now. You get the 90-Day Done Right Promise in writing. If anything’s not right, one call brings us back.
How Much Does Chimney Repair Cost in Commack?
What moves the price is access (two-story roof, steep pitch, tight chimney chase), how much masonry has to come out, and whether the crown needs rebuilding at the same time. A free estimate from Top Hat Chimney includes a camera inspection and a written price. You also get a free second opinion on any competing written estimate from another company. And if the repair is over $200, take $40 off. Seniors and veterans get 10% off, always. Call (631) 502-3612 and we’ll give you the real number for your chimney, not a range from a website.
