Our Chimney Repair Services in Kew Gardens Hills
Mortar Repointing
The brick homes of Kew Gardens Hills were built with lime-based mortar that has a lifespan of roughly 50 to 70 years. Many are now past that mark. We grind out deteriorated joints to proper depth and repoint with matching mortar formulated for Queens freeze-thaw exposure. On homes along Kissena Boulevard and the side streets between Main Street and 164th Street, we’ve found that original mortar has turned to powder behind intact brick faces, hiding serious joint failure until water intrusion becomes visible inside.

Spalling Brick Repair
Spalling, the flaking and crumbling of brick faces, is unmistakable on Kew Gardens Hills chimneys after a hard winter. Moisture enters the porous brick, freezes, and pushes off the face. We remove damaged units and install matching brick, or we apply professional-grade resurfacing compounds when wholesale replacement isn’t required. The urban heat-island effect here, combined with cold damp winters, accelerates the damage cycle compared to more open parts of Queens.

Chimney Waterproofing
Waterproofing a Kew Gardens Hills chimney requires breathable, vapor-permeable sealers, not the hardware-store coatings that trap moisture inside. We apply treatments from professional-grade lines that allow the masonry to exhale while blocking rain entry. Given the density of 11367 and the shared chimney chases common on these blocks, preventing water intrusion in one unit protects the adjoining structure as well.

Flashing Repair
Step flashing and counterflashing where the chimney meets the roofline are common leak points on the low-slope roofs typical of Kew Gardens Hills two-family homes. We fabricate and install custom flashing that integrates with existing roofing, using materials that match the thermal movement of the surrounding structure. A proper flashing repair here often prevents the larger expense of interior ceiling and wall restoration.

Chimney Rebuilding
When deterioration exceeds what repointing and partial repair can address, we rebuild. This is more common in Kew Gardens Hills than in newer neighborhoods for obvious reasons. We rebuild from the roofline up, or we perform partial rebuilds of specific elevations, always matching existing brick and maintaining structural continuity with adjoining units where party-wall chases are involved. Every rebuild includes a proper crown and, where indicated, a compatible flue liner system.

Tuckpointing
For chimneys where the mortar joints are sound but weathered, tuckpointing restores the clean, narrow joint lines that protect the wall while improving appearance. On the uniform brick rows of Kew Gardens Hills, this preserves the architectural character that makes these homes distinctive.

Trusted Brands We Service in Kew Gardens Hills
We stock our Kew Gardens Hills service trucks with professional-grade materials from DuraFlex, HeatShield, and Famco, not builder-grade substitutes that fail in two seasons. DuraFlex 316L stainless liners handle the acidic condensation from gas conversions in oversized flues. HeatShield cerfractory resurfacing restores deteriorated clay liners without full replacement when conditions permit. Famco caps and dampers seal out water and wildlife. Because we carry these materials, most Kew Gardens Hills repairs don’t wait on parts.
Common Chimney Repair Problems We See in Kew Gardens Hills Homes
- Original chimney crowns cracked along the same seam, block after block. In Kew Gardens Hills, the 1950s poured-concrete crowns crack along a distinct seam because the clay liners expanded differently than the surrounding brick over 70 winters. We spot this pattern constantly. A quick crown inspection is almost always billable as a follow-on service here, and catching it early prevents the water intrusion that destroys the chimney below.
- Oversized flues trapping acidic condensation from gas conversions. The neighborhood’s oil-to-gas conversion history left wide clay-tile flues serving low-output gas appliances. The mismatch traps cool, acidic condensation that dissolves mortar joints and creates CO backdraft risk. Cleaning alone cannot fix this; a relining assessment is required.
- Freeze-thaw spalling on exposed brick faces. After each Queens winter, we field calls from Kew Gardens Hills homeowners who’ve noticed new brick damage. The 1940s-1960s masonry absorbs moisture through deteriorated mortar, and repeated freezing pops off the brick face. Early repointing prevents the spiral.
- Shared chimney chase deterioration affecting adjoining units. The attached and semi-detached homes of 11367 often share chimney structures. A deteriorating flue in one unit compromises the gas-tightness and structural integrity of the neighbor’s chimney. We inspect party-wall conditions and document findings both homeowners can review.

FAQs - Chimney Repair in Kew Gardens Hills
Yes, you likely need a relining assessment. The original wide clay-tile flue was sized for an oil boiler running at higher temperatures; your gas appliance produces cooler exhaust that condenses inside the oversized flue, creating acidic moisture that destroys mortar joints and risks CO backdraft. We inspect with a Level-2 camera, show you the photos, and quote DuraFlex 316L relining if the damage warrants it. Call (855) 950-3861 for a free inspection.
Yes, it is common here. The original 1950s poured-concrete crowns crack along the same seam on block after block because the clay liners expanded differently than the surrounding brick over 70 winters. We’ve repaired this exact pattern on 73rd Avenue, Kissena Boulevard, and throughout 11367. The crack allows water into the chimney structure below, so it should be addressed promptly. Crown repair or rebuild in Kew Gardens Hills typically runs $800-$2,200. Call for an exact quote.
Yes, and you should have your flue inspected. Kew Gardens Hills’s semi-detached and two-family homes often share chimney chases and party walls. A deteriorating flue in one unit can compromise the structural integrity or gas-tightness of your adjoining chimney. We documented this exact situation on a 1950s semi-detached home on 73rd Avenue, where a cracked clay liner was leaking CO into the neighbor’s basement. We recommend coordinating inspections when possible. Call (855) 950-3861.
Crown repair and mortar repointing are the most common, usually performed together. The original crowns are failing predictably after 70 years, and the mortar behind them has often turned to powder. Most Kew Gardens Hills jobs we quote involve some combination of crown work and joint repair, with relining recommended when gas conversion condensation has accelerated deterioration. We complete most repairs in a single visit. Call for a free estimate.
Queens chimneys, including those in Kew Gardens Hills, face more severe freeze-thaw stress than parts of Manhattan or Staten Island because of the urban heat-island effect combined with cold, damp winters. Dense development creates rapid temperature swings: the chimney warms during the day from surrounding building heat, then freezes hard at night. This differential thermal expansion widens hairline cracks in old clay liners and accelerates spalling of brick faces. The 1940s-1960s masonry in 11367 is particularly vulnerable because it has reached the age where original materials are fatigued. Annual inspection catches this before catastrophic failure.
