Our Chimney Repair Services in Glendale
Mortar Repointing
Glendale’s pre-war brick rowhouses were built with lime-based mortar that has now endured nearly a century of Queens winters. The freeze-thaw cycle here is brutal on aging joints, especially on chimneys exposed above the roofline without the windbreak that Manhattan’s taller buildings provide. We grind out deteriorated mortar to proper depth and repoint with professional-grade mixes formulated for historic masonry, not the fast-set products some crews use. A typical mortar repointing job on a Glendale rowhouse chimney runs $1,200-$2,400, depending on how many courses need attention and whether scaffold access is required.
Spalling Brick Repair
Spalling, the flaking and crumbling of brick faces, is epidemic on Glendale chimneys because moisture penetrates through failed mortar joints, then expands when it freezes. We’ve replaced entire courses on chimneys near Cooper Avenue where the spalling had progressed to structural compromise. Our technicians match replacement brick for color and hardness, then seal the repair to slow future water intrusion. Most spalling repairs in Glendale fall between $650 and $1,800.
Chimney Waterproofing
Water is the enemy of every masonry chimney, but in Glendale’s dense rowhouse blocks, the problem compounds. Shared party-wall chimneys often have one side maintained and one neglected, so moisture migrates through the masonry from the unmaintained flue into the maintained one. We apply vapor-permeable waterproofing treatments that let the brick breathe while shedding rain, critical for chimneys that can’t dry from all four sides. Chimney waterproofing in Glendale typically costs $450-$950 and includes crown sealing and flashing inspection.
Flashing Repair
The step flashing where your chimney penetrates the roof is a common leak point on Glendale’s older homes, many of which have seen multiple roof layers installed with flashing that was never properly integrated. We remove compromised flashing, install new copper or lead flashing woven correctly with the shingles, and seal with professional-grade compounds. Flashing repair in Glendale generally runs $350-$850 for standard configurations.

Trusted Brands We Service in Glendale
We don’t use builder-grade substitutes. For Glendale chimneys, we specify Gelco stainless steel caps and screening that withstand Queens weather without rusting through in five years. For liner restorations, HeatShield’s cerfractory sealant lets us restore deteriorated clay tile flues without full replacement when conditions permit. Olympia Chimney and Famco components are stocked on our trucks, so most Glendale repairs don’t wait on parts orders. When we recommend a brand, it’s because we’ve watched it perform on local chimneys for years, not because a distributor offered a spiff.
Common Chimney Repair Problems We See in Glendale Homes
- Unlined or oversized flues venting modern gas appliances. Original coal and oil flues in Glendale rowhouses are often too large for today’s gas boilers and water heaters. The slow, cool exhaust condenses and produces creosote buildup far exceeding what you’d see in a properly sized flue. We regularly find two inches of glazed creosote in flues that were never designed for gas.
- Party-wall chimneys with split maintenance. Because so many Glendale homes share chimney stacks, one owner’s diligent care can mask a neighbor’s neglect. Moisture and combustion gases migrate through shared masonry, causing damage on the maintained side that puzzles homeowners who thought they’d done everything right.
- Freeze-thaw spalling on crowns and exposed brick. Glendale’s urban location means temperature swings hit hard and fast. A January day that starts at 35°F and drops to 15°F overnight will destroy a compromised crown in a few seasons. Annual inspection catches this before bricks start raining onto your roof.
- Original clay tile liners from the 1930s with cracked or missing sections. We’ve pulled liner fragments from Glendale flues that crumbled at the touch. When clay tile fails, exhaust gases can enter wall cavities or neighboring flues, a genuine carbon monoxide hazard that no homeowner should ignore.

FAQs - Chimney Repair in Glendale
You can reline only your flue, but it may not solve the problem and could violate NYC DOB code if cross-contamination risk remains. We worked on a semi-detached rowhouse on 80th Street where the owner’s gas boiler flue was lined with a new DuraFlex stainless steel liner, but the adjacent flue on the party wall-serving the neighbor’s gas boiler-was bare, unlined clay tile from the 1930s. We tested for cross-draft and found measurable CO spillage; our team installed a HeatShield liner in the neighbor’s flue and sealed the shared crown to comply with NYC DOB code, preventing an invisible threat. If you suspect this situation, call (855) 950-3861 for an inspection that includes cross-draft testing.
Your flue was probably built for coal or oil, not gas. Original flues in Glendale’s 1920s-1940s rowhouses are oversized for modern gas appliances, so exhaust moves slowly and cools before escaping. That condensation creates glazed creosote that builds up fast. A properly sized stainless steel liner, typically $2,800-$4,500 installed, corrects the draft and nearly eliminates this problem. Call for a free inspection and we’ll measure your flue against what your appliance actually needs.
It depends on the damage pattern, which our camera inspection will show you. Isolated cracks and gaps often qualify for HeatShield cerfractory restoration at $1,800-$3,200, saving the liner and avoiding demolition. If tiles are missing, shifted, or deteriorated throughout, we recommend a new DuraFlex stainless steel liner. We’ll show you the photos and give you both options with prices. No pressure either way.
Most Glendale chimneys need mortar inspection every 2-3 years and repointing every 10-15 years, but the freeze-thaw exposure here accelerates deterioration. If you see mortar crumbling from joints or white efflorescence staining the brick, you’re already overdue. Annual Level-2 camera inspection catches joint failure before water enters and starts spalling bricks. Our $89 seasonal tune-up includes a visual mortar assessment.
Draft reversal in shared party-wall chimneys where one flue is maintained and the other is not. Combustion gases from the neglected flue can backdraft into the maintained flue or even into living spaces, a carbon monoxide risk that produces no visible symptom until it’s tested. This condition is specific to Glendale’s rowhouse density and pre-war construction, and it’s why we test for cross-draft on every party-wall inspection. Call (855) 950-3861 to schedule this test, estimates are free.
