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 Brooklyn Heights
Chimney repair in Brooklyn Heights usually costs between $450 and $2,800 depending on what the camera finds, and most jobs are completed in a single visit. We work on brownstones along Hicks Street, Henry Street, and Willow Street every week, and our technicians know the building stock here better than most out-of-area companies ever will. If you own a Federal or Greek Revival row house with an original stack, call (516) 240-9191 and we’ll start with a Level 2 camera inspection, not a guess.
Why Level Two Chimney Flushing Is Brooklyn Heights’s Preferred Chimney Repair Company
The reason our Chimney Repair team keeps getting called back to Brooklyn Heights is straightforward: we document what we find before we ask you to spend a dollar. Since 2009, we’ve made camera-scan documentation the default on every visit under Clause 4 of the Haven Standard. You see the video. You see the photos. Then we write the scope and the price, in writing, before anyone touches a brick. That matters in this neighborhood, where a 170-year-old stack can hide four different problems behind one cracked crown.
Corrine Halstead, who leads Level Two Chimney Flushing, set that standard years before any regulator or insurer required it. Her crews are background-checked, uniformed, and work to NFPA 211 Level 2 on every inspection, not just the ones that look bad from the sidewalk. Brooklyn Heights homeowners who’ve had a bad experience with a company pointing a flashlight up the flue and quoting $8,000 tend to appreciate the difference.
We answer our phones with a live person 24 hours a day. A named technician is assigned to your job, and you get a text when they’re on the way. For a neighborhood that runs on co-op boards, Landmarks paperwork, and tight schedules, that’s not a luxury. It’s how the work should work.
Our Chimney Repair Services in Brooklyn Heights
Mortar Repointing
Brooklyn Heights brownstones sit on a bluff above the East River, and the harbor-facing sides of their chimney stacks take a beating. Salt-laden air works into the mortar joints, dissolves the lime binder, and leaves the brick face loose. Repointing in Brooklyn Heights typically runs $45 to $85 per square foot depending on access, scaffold needs, and joint depth. We match the original mortar color and composition, because the Landmarks Preservation Commission notices when someone repoints a Federal row house with Portland-rich gray mortar that was never part of the original palette.
Spalling Brick Repair
Spalling is what happens when water gets into old soft brick, freezes, and pops the face off. On a 1840s Greek Revival stack overlooking the harbor, we’ve seen the entire river-facing side shed brick shingles after decades of nor’easter spray. Repairing spalled brick in Brooklyn Heights runs $600 to $2,200 per section, depending on how many bricks need replacement and whether we’re matching historic brick reclaimed from period salvage. We document the damaged area on camera before we lay a single replacement, so you’re never taking a contractor’s word that the wall was failing.
Chimney Waterproofing
Waterproofing a chimney in Brooklyn Heights should cost between $1,100 and $2,600 for a standard three-flue brownstone stack. The key is using a vapor-permeable sealant that keeps harbor moisture out while letting the masonry breathe. Sealing a chimney with the wrong product traps moisture inside the brick, which accelerates freeze-thaw damage in a climate with real winters. We use penetrating siloxane products and document the application area with photos, because waterproofing is invisible once it’s dry and you need a record it was actually done.
Flashing Repair
Broken or corroded flashing is the most common fixable cause of chimney leaks in Brooklyn Heights, and it’s also the one most often misdiagnosed by someone who wants to sell you a rebuild instead. Flashing repair runs $450 to $1,400 on most row house stacks, though a full replacement with custom-bent copper on a complex historic roofline can run higher. The tell signs are water staining on the ceiling near the chimney chase or rust tracks along the roofline. Our camera inspection traces the leak before we quote the fix.
We also handle chimney rebuilding and tuckpointing when the damage is structural, but we’ll never recommend a rebuild without video of the interior flue and mortar readings to back it up. In Brooklyn Heights, where a rebuild on a landmarked property can triple in cost once LPC review and historic mortar matching are factored in, that evidence protects you from paying for work the stack doesn’t need.

BeforeAfterTrusted Brands We Service in Brooklyn Heights
When a Brooklyn Heights chimney needs a stainless flue liner, a chimney cap, or a waterproofing system, we install materials from DuraFlex, HeatShield, and Olympia Chimney. These aren’t budget brands; they’re what the code-compliant jobs in this neighborhood actually require, and we stock common sizes and profiles so a liner replacement on a Henry Street brownstone doesn’t sit open to the weather while parts ship from a warehouse. If you already have a written quote from another company, bring it to us. We’ll give you a free second opinion on the scope and the price, in writing, under Clause 1 of the Haven Standard.
Common Chimney Repair Problems We See in Brooklyn Heights Homes
- Harbor-facing mortar washout. Chimneys on the west and northwest faces of stacks along the Promenade, Columbia Heights, and the bluff see direct salt spray during nor’easters, which erodes mortar joints on the windward side years before the rest of the stack fails.
- Unlined boiler flues in converted brownstones. Decades of single-family to multi-unit conversion left many original three- and four-flue stacks venting modern gas boilers into fifty-foot masonry chases with no clay tile liner, which is against current NYC code and creates condensation damage inside the masonry.
- Abandoned flues that were informally blocked years ago. When a floor was converted to a rental or a fireplace was decommissioned, someone stuffed insulation or shoved bricks into the flue, trapping moisture and weakening the stack from the inside, which camera inspection catches immediately.
- Non-approved chimney cap replacements. Swapping a deteriorated cap for a visually different profile without Landmarks Preservation Commission approval has triggered stop-work orders and forced removal of completed work, a problem we see from homeowners who used a contractor unfamiliar with Brooklyn Heights rules.

FAQs - Chimney Repair in Brooklyn Heights
If the repair maintains the same profile, materials, and visual character, the Landmarks Preservation Commission generally treats it as maintenance and no Certificate of Appropriateness is required. If the crown profile changes, if the cap style differs, or if the work involves adding or removing masonry elements, LPC review is mandatory before work begins. We handle this paperwork for Brooklyn Heights jobs where it applies, and we’ll tell you on the inspection whether your specific repair crosses the line into permit territory. Call (516) 240-9191 and we’ll walk you through what your stack actually needs.
Because salt-laden harbor air and nor’easter wind pressure hit the windward face directly, accelerating mortar erosion on the river-facing side. The chimney acts like a sail, driving wind-driven spray into the crown and the upper brick courses. This is a failure pattern we see on stacks along the Promenade and the western blocks of Brooklyn Heights far more than inland, and it’s why we always inspect the harbor-facing elevation with the camera before we recommend any repair scope. Call (516) 240-9191 for an inspection that looks at the whole stack, not just the street side.
No. Current NYC code requires a code-compliant liner for gas and oil appliance venting; an unlined masonry flue is a fire and carbon monoxide hazard, and it usually fails inspection when a building or co-op does a Certificate of Occupancy or insurance review. We scope these flues on camera, document the lack of a liner, and provide a written plan for installing a stainless liner sized correctly for the appliance before we recommend anything else. Call (516) 240-9191 to schedule an inspection and get the scope in writing.
In most cases yes, if the work is interior to the flue or if exterior repointing uses mortar carefully matched to the original in color, texture, and aggregate. LPC rules protect the visual character of the landmark facade, not the structural maintenance of the chimney, so clean-out-appropriate work sometimes proceeds without a Certificate of Appropriateness. The important thing is documenting that the work is maintenance, not alteration, and having a contractor who knows where that line sits. We’ll tell you on the inspection which category your job falls into. Call (516) 240-9191.
Because a Brooklyn Heights chimney is a 130- to 180-year-old multi-flue masonry system; what’s wrong on the surface often has nothing to do with what’s failing underneath, and you need to see the cause before you agree to the work. On a recent mid-1800s Greek Revival row house overlooking the harbor, we scoped a stack where salt-laden wind had washed out mortar on the harbor-facing side. The camera then showed a boiler flue with no clay tile liner venting into a 150-year-old masonry chase never designed for it. The quote was different once we had the video. That’s why Clause 4 of the Haven Standard requires a camera-scan inspection with a documented photo record on every visit, not just the complicated ones. Call (516) 240-9191 to get your stack on camera.
