Robert Garcia, owner and lead technician at Apex Chimney Cleaning Greater New York, has spent 17 years working on chimneys exactly like yours: original brick stacks built in the 1920s through 1940s, many with dual flues that haven’t been properly evaluated since the original coal furnace got swapped for gas. Kenmore’s roughly one-square-mile footprint means we’re never more than a few minutes away when you call (866) 884-9512. Our Chimney Repair team knows that in ZIP 14217, “chimney problems” aren’t hypothetical—they’re the predictable result of century-old masonry meeting Lake Erie’s worst weather.
Why Apex Chimney Cleaning Greater New York Is Kenmore’s Preferred Chimney Repair Company
We’ve earned our reputation in Kenmore one bungalow at a time. With 1,096 verified customer reviews averaging 4.7 stars, homeowners here recognize that our volume of documented outcomes reflects consistency—not luck. Robert Garcia handles the work himself on every job, so when you schedule a repair on your Kenmore property, you’re getting the decision-maker on your roof, not a subcontractor learning your chimney on the fly.
Our response time to Kenmore averages same-day or next-day during the busy fall and winter seasons, because we know that a cracked crown in November doesn’t wait for a convenient appointment window. We understand the local building patterns: the shared chimney stacks on Elmwood Avenue duplexes, the single-flue bungalows near Mang Avenue with their original clay liners, the two-story homes around Colvin Boulevard that converted to gas in the 1980s and never got their flues resized. That specific knowledge means faster diagnosis and repairs that actually solve the underlying problem—not just patch what’s visible.
Our Chimney Repair Services in Kenmore
Mortar Repointing
Kenmore’s 40–60 annual freeze-thaw cycles turn soft mortar into powder faster than almost anywhere else in Erie County. We grind out deteriorated joints to proper depth and repoint with color-matched, weather-resistant mortar formulated for Buffalo-area conditions. On a typical Delaware Avenue bungalow, full stack repointing runs $1,800–$3,200 and restores structural integrity for decades.
Spalling Brick Repair
Spalling—where brick faces flake and crumble from moisture saturation—is practically standard equipment on Kenmore chimneys after age 70. We remove damaged units, source matching replacement brick where possible, and rebuild compromised courses. For a 1920s Craftsman with moderate spalling on two or three courses, expect $900–$1,800. Severe cases requiring partial rebuild start around $2,500.
Chimney Waterproofing
Lake-effect snow sits on Kenmore chimney crowns for days, wicking through masonry that was never designed for this volume of moisture. We apply vapor-permeable sealers that let the brick breathe while blocking water entry—critical when your stack endures repeated saturation and refreezing. Standard waterproofing for a single-flue bungalow runs $400–$700, with crown sealing included.
Flashing Repair
The junction where your chimney meets the roof is a notorious leak point on Kenmore’s older homes, many of which have seen multiple roofing layers without proper flashing updates. We install stepped counterflashing and base flashing with proper integration into existing roofing. Most flashing repairs here fall between $350–$850, depending on roof pitch and accessibility.

Trusted Brands We Service in Kenmore
We install professional-grade materials from DuraFlex, HeatShield, and Famco—the same lines commercial contractors use, not hardware-store substitutes. For Kenmore homeowners with deteriorated clay tile liners, DuraFlex stainless steel relining systems provide a code-compliant, properly sized flue path for modern gas appliances. HeatShield’s cerfractory resurfacing can restore cracked clay liners in select cases, saving the cost of full replacement when conditions allow. We keep common sizes and fittings in stock, so most Kenmore repairs don’t face parts delays. Robert Garcia specifies materials based on what your specific chimney needs—not what happens to be on sale this month.
Common Chimney Repair Problems We See in Kenmore Homes
- Cracked or separated clay tile liners from decades of under-firing. When your 1920s chimney was built for a coal furnace roaring at 1,200°F and now serves a 80% efficient gas unit cycling at 300°F, the flue never gets hot enough to drive out condensation. That constant moisture weakens clay tiles until they crack or shift, creating gaps where carbon monoxide can escape into wall cavities.
- Moisture wicking through spalled brick and deteriorated mortar during freeze-thaw cycles. Kenmore’s position in the lake-effect corridor means your masonry gets saturated repeatedly each winter. Water expands 9% when it freezes, and after 40–60 cycles annually, even sound brick starts to deteriorate. We regularly find interior wall damage on Mang Avenue and Lincoln Boulevard homes where this has gone unaddressed for years.
- Abandoned furnace flues left open to the elements. That second flue on your dual-flue chimney—the one that served the original coal or oil furnace? After conversion, many homeowners never seal it. Cold outside air and moisture funnel straight down into your walls all winter, creating drafts, mold conditions, and accelerated decay of adjacent framing. It’s one of the most preventable problems we find in Kenmore.
- Crown cracking and cap failure after every winter. The concrete crown at your chimney’s top takes the worst abuse. Post-winter inspections on Colvin Boulevard and Kenmore Avenue properties routinely reveal crown cracks that started small in October and propagated through March. Caught early, crown repair runs $400–$900; ignored, water enters the stack body and you’re looking at partial rebuild territory.

These ranges reflect Kenmore’s specific market: older masonry requiring careful matching, compact lots with tight access, and the near-certainty that we’ll find secondary issues once we open up a century-old stack. What drives cost up: full liner replacement on a dual-flue chimney, extensive spalling requiring brick matching, or structural rebuilds where freeze-thaw damage has compromised multiple courses. What keeps cost down: catching crown cracks early, sealing abandoned flues before they cause interior damage, and addressing mortar deterioration before water enters the stack body.

FAQs — Chimney Repair in Kenmore
Your dual-flue chimney was built to serve two separate appliances: typically a coal or oil furnace on one flue and a wood-burning fireplace on the other. After furnace conversion to gas, the furnace flue is often abandoned but should be properly sealed to prevent cold air and moisture infiltration into your walls. We evaluate both flues during inspection and can seal the unused one while ensuring your active flue is properly sized and lined for safe operation—call (866) 884-9512 for a free assessment of your specific configuration.
Annual inspection is the minimum for Kenmore properties; we recommend post-winter checks every March or April to catch crown and mortar damage before the next heating season. The 40–60 freeze-thaw cycles typical in Erie County accelerate deterioration significantly faster than inland climates, so damage that might take five years elsewhere can progress in two here. Schedule your inspection by calling (866) 884-9512—estimates are free and we’ll flag anything that needs attention before fall.
Most crown cracks in Kenmore can be repaired if caught before water enters the masonry below—crown repair or replacement typically runs $400–$1,200 versus $2,500–$4,500 for partial rebuild. We use crown-specific formulations that flex slightly with thermal movement, critical given Buffalo’s temperature swings. If the crack has allowed water into the stack body for multiple seasons, Robert Garcia will show you exactly what we’re seeing and recommend the most cost-effective path forward—call (866) 884-9512 to schedule.
Spalling is when the face of a brick flakes or crumbles off due to moisture trapped inside freezing and expanding; it’s ubiquitous on Kenmore’s 70–100-year-old chimneys because decades of lake-effect saturation have compromised their protective skin. Once spalling starts, it accelerates—exposed inner brick absorbs water even faster. We replace spalled units with matching brick and address the moisture source, typically for $900–$1,800 on a localized repair. For an exact scope and quote on your stack, call (866) 884-9512.
If your original flue is unlined clay tile or bare brick—and especially if you’ve converted to gas—you almost certainly need a liner for safety and code compliance. Under-fired gas appliances in oversized masonry flues produce acidic condensation that deteriorates mortar and allows carbon monoxide leakage; it’s one of the most serious hazards we find in Kenmore’s converted bungalows. A DuraFlex stainless steel liner properly sized for your appliance typically runs $2,200–$3,800 installed. Robert Garcia will measure your flue and appliance output to specify exactly what you need—call (866) 884-9512 for a free evaluation.
