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.

We’ve been dispatching crews to Forest Hills from our New York City office for decades. We know the difference between a Forest Hills Gardens Tudor with its original 1910s multi-pot terracotta stack and a Queens Boulevard pre-war co-op with a shared masonry system serving twelve units. That local knowledge matters because the wrong repair on the wrong chimney type can make things worse. Our Chimney Repair team treats every stack like the specific structure it is, not like a generic flue.
Why Hearthstone Chimney Co. Is Forest Hills’s Preferred Chimney Repair Company
Forest Hills homeowners call us because we’ve earned a reputation for plain talk and no upselling in Queens neighborhoods where older chimneys are routinely oversold. Our reviews from Forest Hills customers consistently mention the same things: the technician showed them the camera footage, explained what was actually wrong, and didn’t push work they didn’t need. We answer the phone with a live person 24 hours a day, 7 days a week, and our background-checked, uniformed technicians arrive when we say they will.
We coordinate dispatch from our New York City office, which means Forest Hills is in our regular rotation, not a distant add-on. Most jobs are completed in a single visit. Our no-hassle upfront pricing means the number on the estimate is the number on the invoice. And every repair is backed by our 90-Day Done Right Promise in writing - if it’s not right, we come back, no arguing, no paperwork chase.
What separates us from out-of-neighborhood crews is this: we understand that Forest Hills Gardens’ signature multi-pot chimney stacks - three or four terracotta pots serving separate flues - require draft-balancing knowledge that single-appliance chimney training doesn’t cover. Capping one flue without accounting for the others can backdraft a water heater into living spaces. We’ve seen it happen after other companies “fixed” the fireplace flue and left.
Our Chimney Repair Services in Forest Hills
Chimney Rebuilding
Full chimney rebuilding in Forest Hills runs $4,500-$8,500 depending on height, access, and whether the original multi-pot terracotta top needs replication. We rebuild only what’s actually necessary. On a 1920s Tudor on Greenway South in Forest Hills Gardens, our tech found the original clay-tile flue liner cracked and the lime mortar crown spalling after decades of freeze-thaw; we ran a camera and showed the homeowner third-degree creosote glaze near the smoke chamber that a brush couldn’t touch, then installed a HeatShield liner and rebuilt the crown. Because the stack had three separate flues, we balanced the draft across the fireplace and boiler vents so the water heater didn’t backdraft. We don’t recommend rebuilding from a ground-level glance. Camera first. Verdict second.

Flashing Repair
Flashing repair in Forest Hills typically costs $650-$1,200. Queens’ spring and fall nor’easters drive rain into compromised flashing at the chimney-roof intersection, and in Forest Hills Gardens’ 80-110-year-old homes, the original step-flashing was often installed before modern ice-and-water shield standards existed. We remove the old flashing, inspect the deck and masonry beneath for hidden moisture damage, and install new galvanized or copper flashing with proper counterflashing reglets. We use professional-grade materials from Gelco and Famco, not builder-grade substitutes that’ll fail in five years.

Chimney Waterproofing
Chimney waterproofing in Forest Hills runs $800-$1,500 for a typical single-family stack, with larger multi-pot or shared systems running higher. We apply vapor-permeable sealers from Olympia Chimney that let the brick breathe while blocking water penetration - critical in Forest Hills, where humid continental winters deliver repeated freeze-thaw cycles that destroy chimneys sealed with non-breathing coatings. The wrong product traps moisture inside and accelerates spalling. We specify the right one for your masonry type and exposure.

Mortar Repointing & Tuckpointing
Targeted mortar repointing in Forest Hills costs $350-$950 depending on access and how many courses need work. Forest Hills Gardens’ century-old lime-based mortar joints are softer than modern Portland cement - that’s by design, but it means they erode faster under freeze-thaw stress. We match the original mortar composition and joint profile so the repair blends with the historic fabric. Tuckpointing for cosmetic refinement on decorative brickwork is available where the structural mortar is sound.

Spalling Brick Repair
Spalling brick repair in Forest Hills ranges from $450 for localized replacement to $2,800-$4,200 when spalling indicates deeper freeze-thaw damage requiring partial rebuild. Spalling on Forest Hills Gardens chimneys often starts at the crown and works down - the crown cracks, water enters, winter freezes it, and the brick face pops off. We replace damaged brick with matching units and address the crown source so it doesn’t repeat.

Trusted Brands We Service in Forest Hills
We stock professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney for Forest Hills jobs, which means faster turnaround and no waiting on special orders for standard repairs. HeatShield’s cerfractory flue liner resurfacing system is particularly valuable in Forest Hills Gardens homes where the original clay-tile liner is cracked but a full stainless replacement would disturb the historic multi-pot terracotta top. We specify the right product for the specific condition, not the most expensive option in the catalog.
Common Chimney Repair Problems We See in Forest Hills Homes
- Draft imbalance after single-flue capping. A Forest Hills Gardens homeowner caps the fireplace flue to stop drafts, and the water heater backdrafts because the stack’s three-flue system was never rebalanced. We see this several times a year from out-of-neighborhood companies who didn’t account for the multi-pot design.
- Cracked clay-tile liner in the “unused” secondary flue. After coal-to-gas conversion decades ago, many Forest Hills Gardens homes left the boiler or water heater flue unlined. The clay tile cracks, CO risk rises, and the homeowner doesn’t know because the flue was never inspected. Our camera finds it.
- Crown spalling misdiagnosed as full rebuild. Ground-level spalling brick on a Forest Hills chimney often traces to a cracked crown letting water behind the face brick. A camera inspection shows whether the flue is sound and the damage is superficial. We’ve saved homeowners thousands by repairing the crown and reflashing instead of rebuilding.
- Shared chimney access conflicts in Queens Boulevard co-ops. The massive masonry systems serving multiple units in 1920s-1950s pre-war buildings require coordinated access for inspection and repair. We work with building management to schedule minimal-disruption access and document the shared flue condition for all stakeholders.

FAQs - Chimney Repair in Forest Hills
Your multi-pot stack was built between 1910 and the 1940s to serve multiple appliances - typically fireplace, boiler, water heater, and sometimes an incinerator stub - through separate flues in a single masonry structure. This was standard design for the Russell Sage Foundation’s planned community, but it creates a repair condition single-appliance chimney codes don’t anticipate: capping or relining one flue changes draft balance across the entire stack. We inspect all flues and calculate the interaction before recommending any modification. Call (516) 531-6315 if you’re considering capping a flue or converting a fireplace - we’ll check the whole system first.
No. Crown mortar deterioration is the entry point for the most expensive damage your chimney can suffer. Once water penetrates through crown cracks, freeze-thaw cycles in Forest Hills winters destroy brick from the inside out. What looks like surface crumbling often masks deeper spalling and liner damage that only a camera inspection reveals. We evaluate the crown, then run the camera to confirm whether the flue is compromised. Sometimes the crown repair is sufficient. Sometimes the liner needs attention too. You get the photo evidence either way before we recommend anything.
Every year, before burning season. NFPA 211 recommends annual Level-1 or Level-2 inspection for all chimneys, and Forest Hills’ conditions make this especially prudent: humid continental winters accelerate freeze-thaw damage in century-old lime mortar, and spring nor’easters test flashing and crown integrity. For Queens Boulevard co-ops with shared masonry systems, we coordinate with building management to inspect on a schedule that serves all units. Call (516) 531-6315 to arrange access - estimates are free.
Third-degree creosote is a hardened, tar-like glaze that bonds to flue walls and resists standard brushing. It forms when wood burns incompletely and smoke cools too quickly in an oversized or unlined flue - common in Forest Hills Gardens fireplaces where the original flue was designed for coal. Brushing glazes it smoother without removing it. We remove it with rotary chemical treatment or, when the underlying liner is cracked, with a HeatShield cerfractory resurfacing or DuraFlex stainless liner installation. The camera shows you the extent before we specify the method.
Yes. Every repair estimate includes a Level-2 camera inspection with photos you can see and a plain-English verdict. We don’t recommend work based on a ground-level glance or a flashlight up the flue. The camera reveals cracked liners, hidden spalling, creosote buildup, and draft obstructions that exterior inspection misses. In Forest Hills Gardens’ multi-pot stacks, it also lets us map how the separate flues interact. The inspection is included at no separate charge. Call (516) 531-6315 to schedule - you’ll see what we see before any work is discussed.
