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 Crown Heights
Chimney repair in Crown Heights usually means dealing with a masonry stack that’s been standing since before the subway reached Eastern Parkway. Most of the rowhouses between Washington Avenue and Utica were built between 1890 and 1925, and their chimneys carry the original coal-era clay tile flues. When those flues crack, spall, or collapse, you’re looking at repair costs ranging from $450 for a minor mortar patch to $3,800-$6,500 for a full flue reline and top-end rebuild. Wendell Pike has been inside enough Crown Heights chimney stacks to know which ones will hold another season and which ones won’t. Call (516) 289-9316 and we’ll put eyes on it, with camera footage you can see for yourself.
Why Top Hat Chimney Is Crown Heights’s Preferred Chimney Repair Company
We’ve worked the blocks between Crown Heights and the Brooklyn Botanic Garden long enough to know the housing stock the way a mechanic knows a particular engine. The brownstones on President Street, the limestone rowhouses along Carroll, the bluestone-fronted walkups off Rogers Avenue-each one has a chimney stack with quirks, but most share the same underlying problem: decades of deferred maintenance on flues that were never relined when the coal furnaces came out.
Wendell and his crew answer the phone. Not a call center, not a voicemail tree. When you call about a leak sooting up your top-floor bedroom, the person who picks up knows what a parged smoke chamber looks like on camera. And every job, from a simple crown reseal to a full rebuild, carries the 90-Day Done Right Promise in writing. If it’s not right, one call brings us back. No argument, no re-quote, no runaround.
We know Crown Heights because we work Crown Heights. The freeze-thaw cycles that chew through century-old mortar on Franklin Avenue are the same ones that crack terra-cotta crown caps on Bergen Street. Our pricing is straightforward: the number you hear on the phone before you book is the number on the invoice when we’re done. No add-ons at the door, no “scope creep” after the scaffold goes up.
Our Chimney Repair Services in Crown Heights
Mortar Repointing
The mortar joints on a Crown Heights rowhouse chimney take a beating from Brooklyn’s freeze-thaw cycles. When water gets into those joints and freezes, it expands and crumbles the mortar from the inside out. Repointing replaces the soft, sanded-out joints with fresh mortar matched to your brick color and composition. We’ve repointed stacks on Sterling Place that were losing mortar by the handful every winter. Typical repointing on a Crown Heights chimney runs $900-$2,200 depending on stack height and how many courses need work.
Spalling Brick Repair
Spalling is what happens when water penetrates the brick face, freezes, and pops the outer layer off. You’ll see brick chips on the sidewalk or a stack that looks like it’s molting. On the three- and four-story rowhouses around Eastern Parkway and Lincoln Place, we commonly see spalling concentrated at the roofline, where the stack takes the worst weather. Replacing spalled bricks before they compromise the stack’s structure typically runs $450-$1,100 for isolated spots; a full face rebuild of the upper courses runs higher.
Chimney Waterproofing
Waterproofing a Crown Heights chimney means applying a vapor-permeable sealant that keeps rain out while letting moisture inside the masonry escape. It’s not paint, and it’s not a band-aid for structural problems. But the century-old brick on this neighborhood’s rowhouses drinks water like a sponge, and a proper waterproofing application can buy years before major masonry work is needed. Figure $650-$1,400 for a standard residential stack in Crown Heights, depending on surface area and condition.
Flashing Repair
Flashing is the metal barrier where the chimney meets the roof, and in Crown Heights it’s often original galvanized steel from the 1940s, rotted through at the corners. Leaks around the roofline are usually flashing failures before they’re masonry failures. We fabricate and install copper or aluminum flashing on site, cut to your stack’s actual dimensions rather than bent from a generic kit. Expect $500-$1,200 for a typical Crown Heights flashing replacement, including old flashing removal and resealing.
Flue Liner Installation
This is the repair that matters most in Crown Heights, because so many of these buildings never got the liner work they needed when coal heat went out. We install stainless steel liners sized to the appliance actually venting through the flue, not the flue’s original 1890s dimensions. Whether it’s a DuraFlex liner for a gas boiler or a heavier-gauge liner for an oil burner, we camera the flue first, show you what we found, and then quote the job. Expect $2,800-$5,500 for a full liner installation in a Crown Heights rowhouse, depending on stack height and liner diameter.
Chimney Rebuilding
Some Crown Heights chimneys are beyond patching. When the upper courses have shifted, the crown is gone, and the flue tiles are shattered, a partial or full rebuild is the honest answer. We rebuild stacks from the roofline up, matching the original brick as closely as current supply allows, installing a poured concrete crown with proper overhang, and recladding flashing. Partial rebuilds (top 8-12 courses) run $2,500-$4,500; full stack rebuilds start around $6,000 and go up with height and access. We show you the camera footage before we ever recommend a rebuild.

Common Chimney Repair Problems We See in Crown Heights Homes
- Unlined coal-era flues venting modern gas boilers. This is the big one. When a 1950s oil-to-gas conversion happened, the flue wasn’t resized or relined. Gas exhaust is cooler and wetter than coal or oil exhaust, and it condenses inside the old clay tile, dissolving the clay over time. We’ve pulled collapsed tile out of flues on Sterling Place that were still venting a working boiler.
- Freeze-thaw spalling at the roofline. Crown Heights winters don’t stay freezing, they cycle. Water seeps into brick faces, freezes, thaws, and pops the brick apart. By March, the sidewalk under the stack has brick chips on it. The problem compounds every season it’s left unaddressed.
- Abandoned second flues sealed with roof tar. Many Crown Heights rowhouses had parlor fireplaces sealed off decades ago. The flue wasn’t properly capped, it was tarped, tarred, or stuffed with fiberglass. Water gets in, saturates the party wall between your brownstone and the one next door, and you find damp plaster on the third floor. Proper sealing takes a real capped flue, not a bucket of roofing cement.
- Crumbling crowns on low-profile stacks. The crown is the concrete cap on top of the stack, and a century of weather cracks it. Once water gets through the crown, it works into the brick below and the damage accelerates. On the tight canyon streets of Crown Heights, where stacks barely clear the roofline, a cracked crown is an open wound.
Pricing for Chimney Repair in Crown Heights, NY
Here’s the straight answer on what things cost in Crown Heights. A routine repointing job runs $900-$2,200. Flashing replacement lands between $500 and $1,200. Spalled brick repair is $450-$1,100 for isolated damage. Waterproofing a standard stack is $650-$1,400. Flue liner installation is the big-ticket item at $2,800-$5,500, because we’re often replacing what was never installed in the first place. A partial rebuild runs $2,500-$4,500, and full rebuilds start around $6,000. These are real-world ranges for this neighborhood’s three- and four-story rowhouse stacks.

FAQs - Chimney Repair in Crown Heights
Because gas exhaust is different from coal exhaust. Gas burners produce cooler, wetter exhaust, and when that moisture condenses inside a flue built for hot coal gases, it eats the clay tile from the inside out. Your coal flue “never caused a problem” because it was never asked to handle gas. The clay tile installed in 1910 has been dissolving slowly since the boiler conversion in 1962. Our camera shows you exactly how much tile is left. The fix is a stainless steel liner sized to your boiler, not the 1890s flue dimensions. Call (516) 289-9316 for an estimate-free, any time.
Often, yes. If the spalling is limited to a few courses near the top and the mortar joints below are still sound, we can cut out the damaged bricks, replace them with matched stock, and repoint the surrounding joints. The stack doesn’t need a rebuild. What matters is whether the damage is structural or cosmetic, and that’s a judgment based on camera footage and a hands-on look at the stack. We’ll tell you plainly if a patch will hold. The goal is a repair, not a sales pitch.
Yes, and it should be. An open, unused flue is a water inlet and a heat leak. Properly sealing it means installing a cap that blocks rain and snow while allowing any residual moisture to evaporate. That’s the key difference between a real cap and the roof tar or plywood scraps we find on Crown Heights stacks. We cap the abandoned flue at the top, verify it’s sealed from the roof down, and leave you with one working flue instead of two problems.
We test the mortar. Literally. We run a thin blade along the joints; if the mortar crumbles out like sugar, it’s shot and needs repointing. If the brick itself is soft, spalled, or loose enough to pull free with a hand tool, that’s a different conversation. Repointing is the right call when the brick is sound and the mortar is gone. A rebuild is the call when the brick has failed. We show you both on camera and let you feel the wall. The answer should make sense to you, not just to us. Call (516) 289-9316 for a free evaluation.
Expect to see the crack yourself. We run a camera up the stack and bring the footage down to your phone or tablet. You’ll see the crack, the water staining, and the condition of the flue tile below it. If the crown is salvageable with a proper seal, we’ll say so and quote it. If it’s failed past the point of patching, we’ll show you why. No repair is ever quoted on the strength of someone’s word. The camera footage and a plain-English verdict: every time, no exceptions. That’s the way Wendell works.
If your chimney’s been telling you something and you’d rather hear it from a person than a sales script, call (516) 289-9316. Wendell or one of his crew will answer. We’ll set a time that works, show up with a camera, and tell you what’s real and what can wait. Free estimates, honest answers, and the 90-Day Done Right Promise on every job we do in Crown Heights.
