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.
Fast, Reliable Chimney Repair Across Forest Hills
Chimney repair in Forest Hills typically runs $450-$1,800 for repointing and flashing work, while full crown rebuilds range $1,800-$3,400. Most jobs in the Gardens take three to six hours once we’re on-site, and we’ll hand you a written price before any work begins. If you’re in Forest Hills and hearing mortar crumble or seeing water stains on your chimney breast, call (516) 240-9191. We know these houses. We know what century-old multi-flue stacks look like on the inside, because we camera-scope every one of them before pricing a single repair.
Forest Hills has two housing stocks that dominate repair work here: the Tudor and Arts & Crafts homes of Forest Hills Gardens built between roughly 1909 and the 1930s, and the pre-war brick apartment buildings and semi-detached rowhouses on streets like 71st Avenue, Austin Street, and Queens Boulevard. Both share the same underlying problem. Their chimneys were built for coal. They now vent gas and oil appliances. The flues that once carried cool coal smoke now carry warm, wet exhaust, and the original clay tile liners were never designed for that.
Why Level Two Chimney Flushing Is Forest Hills’s Preferred Chimney Repair Company
We’ve worked on more Forest Hills chimneys than we can count, and the pattern is consistent. The Gardens stacks are the most complicated in Queens. A single brick chimney often contains two or three separate flues: one for the decorative fireplace, one for the converted boiler, sometimes a third for a kitchen range that hasn’t been used since the Eisenhower administration. Most homeowners don’t know which flues are active, which are capped, and which are open to the sky. That’s why our baseline job here is a full multi-flue scope and inspection, not a one-flue sweep.
Our approach comes from Corrine Halstead, who built Level Two Chimney Flushing around a simple rule: if a homeowner can’t see the problem with their own eyes, we haven’t earned the work. Every Chimney Repair visit in Forest Hills includes a camera-scope inspection under NFPA 211 Level 2, with the footage shown to you before any pricing conversation. Clause 4 of the Haven Standard has required this photo and video record on every job since 2009. That’s 38,000-plus chimneys documented, and it’s the reason Forest Hills customers call us back when the next issue appears.
Calls are answered by a live person around the clock. Not a voicemail, not a form. When you call (516) 240-9191 about a crack in your crown or spalling brick on a Gardens stack, you’ll talk to someone who can schedule a named, background-checked technician and get you a text when they’re on the way.
Our Chimney Repair Services in Forest Hills

What follows are the four repairs we perform most often in Forest Hills, with the local context that affects each one.
Mortar Repointing in Forest Hills
Queens gets multiple freeze-thaw cycles every winter. Water seeps into old lime mortar, freezes, expands, and crumbles the joint from the inside out. In Forest Hills Gardens, where the brick is often a century old, this is the single most common repair we quote. A typical repointing job on a single-family Gardens chimney runs $650-$1,400, depending on access and the extent of joint deterioration. We cut out the failed mortar to a proper depth and pack in fresh material matched to the original. Patch-over work fails within one freeze-thaw season. We won’t do it.

Spalling Brick Repair in Forest Hills
Spalling is what it looks like when the brick face pops off. On Forest Hills chimneys, this happens when water is trapped inside the brick and freezes. You’ll see flaked brick on the crown, the shoulders, or along the stack face above the roofline. Repairing spalled brick typically costs $300-$900 per section in Forest Hills, depending on how many bricks need replacement and whether the underlying masonry is sound. If the spalling is extensive, we’ll show you on camera before recommending anything more invasive than a targeted brick replacement.

Chimney Waterproofing in Forest Hills
The tree canopy over Forest Hills Gardens is beautiful, and it’s also a chimney problem. Dense shade means brick surfaces stay damp longer after rain, and Queens winters push that moisture through the freeze-thaw cycle repeatedly. A proper masonry waterproofing product, like Gelco’s vapor-permeable water repellent, is not the same as a cheap acrylic sealer. The acrylic traps moisture inside the brick. The Gelco lets it breathe. Waterproofing a full exterior stack in Forest Hills runs $400-$850, and it’s one of the best returns on chimney maintenance in this neighborhood. It buys years before repointing becomes necessary again.

Flashing Repair in Forest Hills
Flashing is the metal where your chimney meets the roof. In Forest Hills, with its mix of slate, tile, and asphalt shingle roofs on steep Gardens gables, flashing takes a beating from both ice and raccoons. The most common sign is a water stain on the ceiling near the chimney, but the leak can also track away from the stack. Flashing repair in Forest Hills runs $550-$1,300 for a standard step-and-counter flashing replacement, more if the cricket is missing and needs to be built. A cricket is the small peaked structure behind the chimney that diverts water around it. Many older Forest Hills homes never had one, and adding one is often the permanent fix.

AfterTrusted Brands We Service in Forest Hills
We stock and install materials from Olympia Chimney, Famco, and Copperfield, sourced through the Haven buying network to keep prices where they should be. For relining work in Forest Hills’s unlined clay-tile flues, we use HeatShield and DuraFlex systems. What that means for you: if a flue needs resurfacing, we don’t have to order in parts and make you wait through another week of boiler exhaust drifting through cracked tile. Common components are in stock, and our Forest Hills jobs typically get scheduled within a few days.
Common Chimney Repair Problems We See in Forest Hills Homes

- Deteriorated clay tile flues in multi-flue stacks. In the Gardens especially, a single stack often serves two or three flues. The clay tiles that line them crack under decades of thermal shock. Once a tile is spalled or missing, the flue is unsafe for any appliance. We scope every flue before recommending a repair.
- Freeze-thaw mortar erosion and brick spalling. Forest Hills’s repeated winter freeze-thaw cycles work through old mortar and cause the brick faces to pop. The north and east exposures on taller stacks fail first. Repointing and targeted brick replacement stop it before the stack needs rebuilding.
- Cracked or missing chimney crowns. The crown is the concrete cap on top of the stack. On century-old Forest Hills chimneys, it’s often cracked through or was poured without an expansion joint. Water gets in at the top and ruins everything below it. Crown repairs should always come before interior waterproofing.
- Water intrusion through failed flashing. The valley where a steep Forest Hills roof meets the chimney is a natural collection point for rain, snowmelt, and leaves. Failed flashing shows up as attic dampness or a ceiling stain. We replace flashing, not caulk over it.

FAQs - Chimney Repair in Forest Hills

Because an abandoned flue is not a neutral flue. It’s often open to the sky, letting rainwater into the same masonry mass that houses your active boiler flue. That water freezes, spalls the brick, weakens the entire stack, and can eventually compromise the active flue. In a three-flue Gardens chimney, we routinely find that the boiler flue is fine while the uncapped decorative flue is causing all the damage. The fix is inexpensive: a proper cap. The inspection is how you know.
You know by having a camera scoped through the flue and watching the footage yourself. That’s standard on every Level Two inspection in Forest Hills. Signs we look for include gaps between clay tile sections, visible cracking, and white efflorescence on the exterior brick where moisture is pushing through. If your boiler is venting warm, moist exhaust into a cracked unlined flue, the exhaust is condensing inside the masonry. That’s a carbon monoxide risk and a structural problem, and it’s visible on camera. Call (516) 240-9191 to schedule a scope. Don’t rely on a visual check from the roof.
Usually, yes. Spalling at the crown is often isolated to a few bricks and the crown’s concrete surface. If the camera scope shows the flue tiles and smoke chamber are intact, we can replace the affected bricks, recast the crown, and waterproof the upper stack. You don’t need a full rebuild just because a few bricks popped. But the camera has to verify what’s underneath before we price that.
Acrylic sealers form a film on the brick surface. Water can’t get in, but water vapor can’t get out either. In freeze-thaw climates like Forest Hills, that trapped moisture freezes and spalls the brick from behind the sealer. A vapor-permeable water repellent like Gelco lets the masonry breathe while keeping liquid water out. We apply it after the repointing is done, not as a substitute for it. The product costs more, but it actually works in a Queens winter.
Yes. On a multi-flue Forest Hills stack, the flues share a single masonry mass. A crack in an abandoned flue can admit water that spalls the brick around the active flue. We’ve also found open flues venting boiler exhaust into the shared stack, which is a hazard even if you never light the fireplace. A quote that only covers one flue in a three-flue stack isn’t a real quote. We scope all three - it takes an extra 20 minutes and it changes what we recommend. Call (516) 240-9191 with any questions.
At a 1920s Tudor on Greenway Terrace, our tech scoped a three-flue stack and found the boiler flue venting warm, moist exhaust into an unlined clay-tile flue that was already spalling from freeze-thaw. The decorative fireplace flue had a collapsed smoke chamber, but the crown was solid. We recommended HeatShield resurfacing on the active flue only, repairs to the smoke chamber, and a Gelco water repellent on the exterior brick. Nothing was priced until the homeowner watched the camera footage with our crew. That’s how it works in Forest Hills: evidence first, then numbers.
