We’ve been working on chimneys in Kew Gardens Hills for 17 years — long enough to know that the neighborhood’s attached brick rowhouses and semi-detached two-families present problems you won’t find in suburban Queens. The tight lot lines along streets like 73rd Road, 150th Street, and Kissena Boulevard mean we’re often working on shared party-wall chimneys where one building’s flue condition directly affects the next. Parking’s tight, ladder access is constrained, and the 1930s–1950s masonry that’s everywhere here has seen decades of freeze-thaw cycles, oil-to-gas conversions, and deferred maintenance. Robert Garcia, our owner and lead technician, handles these jobs personally — not a rotating subcontractor who has to figure out the neighborhood on your dime.
Why Apex Chimney Cleaning Greater New York Is Kew Gardens Hills’s Preferred Chimney Repair Company
Our reputation in Kew Gardens Hills is built on showing up and doing the work right — not on marketing. We’ve earned 1,096 verified customer reviews averaging 4.7 stars across the five boroughs, and a significant share of those come from repeat customers in Queens neighborhoods like this one. When you’re working on a shared chimney in a two-family brick rowhouse, the neighbor’s watching. We’ve earned referrals that way.
Response time to Kew Gardens Hills is typically same-day or next-day, because we’re based in New York City and don’t route crews from Long Island or Westchester. Robert knows the local building stock — the oversized terracotta flues originally built for oil heat, the unlined masonry that’s still venting gas boilers, the spalling brick from decades of Queens freeze-thaw. That familiarity means faster diagnosis and repairs that actually solve the underlying problem, not just patch the symptom.
Our Chimney Repair team doesn’t guess at why your flue is failing. We inspect, we explain, and we fix it with professional-grade materials from brands like DuraFlex, HeatShield, and Famco — the same lines commercial contractors specify.
Our Chimney Repair Services in Kew Gardens Hills
Mortar Repointing & Tuckpointing
The mortar joints on Kew Gardens Hills’s 1930s–1950s brick chimneys are often original — eighty-plus years old, crumbling from freeze-thaw damage and decades of acid rain. We grind out the deteriorated mortar to proper depth and repoint with color-matched, high-compressive-strength mortar formulated for Queens’s climate. On a recent job near Kissena Boulevard, we repointed a shared chimney where the mortar was so degraded that daylight showed through to the flue cavity. That’s a fire and carbon monoxide hazard, and it’s more common here than homeowners realize.
Spalling Brick Repair
Spalling — brick faces flaking and popping off from moisture intrusion — is epidemic in Kew Gardens Hills. The combination of porous older brick, cracked crowns, and the urban heat-island effect that accelerates freeze-thaw cycling means we see spalling on chimneys that look fine from the street. We remove and replace spalled bricks with matching reclaimed or new brick, then address the moisture source. Without that second step, you’ll be repairing the same chimney again in three years.
Chimney Waterproofing
Waterproofing isn’t optional in Kew Gardens Hills — it’s structural preservation. The tightly packed housing stock limits airflow around chimneys, so moisture that gets in doesn’t dry out quickly. We apply vapor-permeable waterproofing agents (we use professional-grade formulations from Copperfield and Famco) that block liquid water while letting the masonry breathe. This is especially critical on shared party-wall chimneys where a leak on one side can damage both units before anyone notices.
Flashing Repair & Replacement
Step flashing and counterflashing on Kew Gardens Hills’s older homes often consists of original galvanized steel that’s rusted through, or amateur repairs with caulk and hope. We fabricate and install custom flashing that integrates properly with your roofing and masonry, using materials matched to your roof type. On low-slope sections common on these rowhouse additions, we pay particular attention to ice-dam vulnerabilities where Queens’s freeze-thaw cycles concentrate damage.
Chimney Relining (Oil-to-Gas Conversion Specialist)
This is where our Kew Gardens Hills expertise matters most. The neighborhood’s housing stock was built for oil heat — oversized terracotta flues designed to handle the high exhaust temperatures and volume of oil combustion. When homeowners converted to gas (as most have), those same flues became dangerously oversized. Modern gas appliances need smaller, properly sized liners to maintain adequate draft and prevent condensation.

We install stainless steel liners from DuraFlex and HeatShield cast-in-place systems sized specifically for your current appliance. This isn’t a generic part swap — it’s combustion engineering that affects your safety and your heating efficiency. Under NYC DOB rules, an improperly lined gas flue is a code violation that can block your Certificate of Occupancy renewal.

Trusted Brands We Service in Kew Gardens Hills
We stock and install professional-grade materials from DuraFlex, HeatShield, Gelco, and Famco — the same brands commercial chimney contractors specify for Queens’s demanding conditions. For Kew Gardens Hills customers, that means no waiting on special orders for standard repairs. When Robert arrives to inspect your chimney, he’s carrying the liners, crowns, caps, and waterproofing materials that match your specific configuration. We’ve learned which products hold up to the urban density and weather exposure this neighborhood delivers, and we don’t install anything we wouldn’t put on our own building.
Common Chimney Repair Problems We See in Kew Gardens Hills Homes
- Oversized flues from oil-to-gas conversions. The original terracotta liners in these 1930s–1950s homes were built for oil heat. Converted to gas without relining, they produce acidic white condensate that corrodes the liner and creates dangerous draft conditions — even in homes that never use the fireplace.
- Shared party-wall chimney neglect. In attached and semi-detached two-families, a deteriorating flue on one side of the wall is a code and safety liability for both units. We’ve found flues so degraded that exhaust was leaking into the neighboring unit’s attic space.
- Freeze-thaw spalling on mid-century crowns. Queens’s winter temperature swings — often above freezing by day, below by night — destroy unsealed masonry crowns. Limited airflow between tightly packed Kew Gardens Hills homes means moisture lingers longer, accelerating the damage.
- Unlined or clay-tile-lined masonry still venting gas appliances. Many buildings here retain original chimneys that were never relined despite fuel-source changes. The clay tiles crack from thermal shock and acidic condensation, creating gaps that allow exhaust into wall cavities.

FAQs — Chimney Repair in Kew Gardens Hills
That white residue is acidic condensate from an improperly sized flue — a nearly universal problem in Kew Gardens Hills’s converted oil-to-gas systems. The oversized terracotta liner cools the exhaust too quickly, causing water vapor and combustion acids to condense on the liner surface. This corrodes the terracotta and can leak exhaust into your home. We see this on most inspections in 11367. Call (866) 884-9512 — relining is required under NYC DOB rules, and we can size the correct DuraFlex or HeatShield system for your appliance.
Yes — a deteriorating flue on a shared party-wall chimney is a code and safety liability for both units. Exhaust can migrate through gaps in the separating wythe, and moisture intrusion from a cracked crown affects the entire structure. We inspect both sides when possible and document conditions for your records. Shared-chimney repairs in Kew Gardens Hills two-families are about half our workload here.
Inspect crowns annually; plan for repair or sealing every 5–8 years given Queens’s freeze-thaw cycling and the neighborhood’s urban heat-island moisture retention. Original concrete crowns on 1930s–1950s chimneys are typically unsealed and crack within a decade. We apply professional-grade crown sealant or pour new reinforced crowns using materials formulated for this climate.
Absolutely — and arguably more necessary than in suburban settings. Kew Gardens Hills’s tight building spacing limits airflow, so moisture that penetrates masonry lingers and accelerates spalling, efflorescence, and freeze-thaw damage. Waterproofing with vapor-permeable products (we use Copperfield and Famco formulations) blocks liquid water while letting masonry breathe. It’s preservation, not cosmetics.
We don’t repair it — we reline it. The original terracotta flue is dangerously oversized for gas combustion and will continue producing condensate and draft hazards regardless of patching. We install a properly sized stainless steel or HeatShield liner, abandon the damaged terracotta in place, and certify the system to current NYC codes. On 73rd Road, we recently relined a shared chimney where the gas side was coated in white acidic condensate — the homeowner thought it was clean. It wasn’t. Call (866) 884-9512 for an inspection.
