We’ve been working in Lockport long enough to know the difference between a chimney on Robinson Road built in 1985 and one on Main Street that’s been standing since the Erie Canal opened. The latter is what makes Lockport unique—and what makes chimney work here genuinely different from newer Buffalo suburbs. Our Chimney Liner & Rebuild team handles everything from stainless steel liner installations in ranch homes near Lockport-Olcott Road to full rebuilds of double-flue stacks in the historic district.

Last winter on Walnut Street, we relined a pre-Civil War double-flue chimney where the homeowner used only the fireplace flue. The second flue, left open and capped with a rotting clay tile, had raccoon nests and a 6-inch ice dam. We installed a DuraFlex stainless steel liner in the active flue and sealed the dormant one, preventing further freeze-thaw spalling of the original dolostone.

Why Titan Chimney Cleaning Greater Buffalo Is Lockport’s Preferred Chimney Liner & Rebuild Company

Local reputation built on showing up. Lockport homeowners don’t want a dispatcher in another county deciding when their chimney gets fixed. Thomas Hernandez, our owner and lead technician, lives in the Greater Buffalo area and routes Lockport calls himself. That means when you call (833) 632-3568, you’re talking to the person who will be on your roof.

Nearly 300 homeowners have trusted us. Our 297 verified reviews averaging 4.7 stars include repeat customers from Lockport’s 14094 and 14095 ZIP codes who’ve had us back for annual sweeps after we handled their liner replacement. They mention the same things: no subcontracted crews, no bait-and-switch, Thomas explains what’s actually wrong before quoting.

Response time that respects your heating season. From our Buffalo base, we’re typically at Lockport homes within 45 minutes to an hour. In January and February, when lake-effect snow from both Erie and Ontario is hammering chimneys on the Escarpment, that speed matters. A backed-up flue on a zero-degree night isn’t a tomorrow problem.

We know what Lockport chimneys are made of. Niagara dolostone. Soft brick from the 1820s. Multi-flue stacks converted from coal to gas to wood and back again. You can’t fake that familiarity, and you can’t learn it from a manual written in Nashville.

Our Chimney Liner & Rebuild Services in Lockport

Stainless Steel Liner Installation

For most Lockport homeowners with a functioning chimney structure but a deteriorated clay flue, a stainless steel liner is the right fix. We install DuraFlex and Olympia Chimney liners sized precisely to your appliance—whether that’s a wood-burning fireplace in a home off Clinton Street or a gas insert in a ranch near the Canalway Trail. A typical stainless steel liner installation in Lockport runs $2,800–$4,200. In the lake-effect zone, the 316Ti alloy we specify resists the acid condensation that forms when cold exterior chimneys meet warm exhaust gases.

Flexible Liner Systems

Lockport’s older homes often have offset flues—shifts built into the chimney stack during original construction to avoid floor joists or roof lines. A rigid liner won’t navigate these. We use DuraFlex flexible liners for offsets in pre-Civil War chimneys along West Genesee Street and similar corridors. Flexible liner installation in Lockport typically costs $3,200–$4,800, slightly more than rigid systems because of the specialized fitting and longer installation time.

Liner Replacement

When an existing stainless steel or aluminum liner has corroded, separated at the joints, or been damaged by a chimney fire, full replacement is necessary. We see this most often in Lockport homes where a previous owner installed a cheap big-box liner that failed within five years. Our replacement jobs include inspection of the surrounding masonry—because in Lockport, if the liner failed, the dolostone or soft brick around it is often compromised too. Liner replacement in Lockport runs $3,500–$5,500 depending on flue count and accessibility.

Partial Chimney Rebuild

This is where Lockport’s geography becomes unavoidable. The Niagara Escarpment funnels cold air and lake moisture directly into chimney crowns and mortar joints. After 150+ freeze-thaw cycles per winter, Niagara dolostone spalls and soft brick crumbles. A partial rebuild—typically from the roofline up, or of a single face of the chimney—addresses structural damage without the cost of full demolition. Partial rebuilds in Lockport range from $4,500–$7,500. We match existing mortar composition where possible to preserve the character of historic homes.

Full Chimney Rebuild

When the entire stack has shifted, the footing has failed, or multiple flues have collapsed internally, we rebuild from the ground up. Full rebuilds are most common in Lockport’s canal-era homes near the ‘Deep Cut,’ where the original soft brick simply can’t tolerate another heating season. We use professional-grade materials from HeatShield and Copperfield, and we rebuild to current NFPA 211 standards while respecting the home’s original proportions. Full chimney rebuilds in Lockport typically cost $6,500–$12,000 depending on height, flue count, and whether the foundation must be repaired.

Trusted Brands We Service in Lockport

We don’t install contractor-grade substitutes. For Lockport’s harsh freeze-thaw environment, we specify DuraFlex stainless and flexible liners, HeatShield cerfractory resurfacing products for flue repair, and Olympia Chimney components for caps and connectors. We stock common liner diameters and fittings locally, which means most Lockport jobs don’t wait on shipping. When you’re staring at a January forecast with two feet of lake-effect snow incoming, that turnaround matters.

Common Chimney Liner & Rebuild Problems We See in Lockport Homes

• Capped second flues hiding catastrophic damage. Canal-era homes in Lockport commonly have two or three flues in a single chimney stack. Homeowners routinely use only one, leaving the capped or open second flue to accumulate a decade or more of moisture damage and starling or raccoon nesting undiscovered until the active flue starts backing up.
• Niagara dolostone spalling from freeze-thaw exposure. The same stone formation exposed by the famous ‘Deep Cut’ makes beautiful, durable masonry—until repeated wet-freeze cycles on the Escarpment pop the surface off in layers. This spalling destroys mortar joints and requires partial rebuilds rather than simple liner replacement.
• Soft brick crumbling under liner expansion stress. Brick from the 1820s–1840s wasn’t manufactured to modern ASTM standards. When a new stainless steel liner heats and expands, it stresses the surrounding masonry. On homes near the Escarpment, we’ve seen original brick disintegrate within two seasons of a liner installation done without proper clearance or structural assessment.
• Coal-era flues improperly converted for gas inserts. Many Lockport Victorians retain flues sized for coal boilers—too large for modern gas appliances, causing condensation and draft failure. We resize these with proper liner systems, not amateurish block-offs that violate manufacturer requirements.
