Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Alcott Chimney Sweep Is Lockport’s Preferred Gas Fireplace Repair Company
We’ve worked on enough Lockport homes to know what the other guys miss. The housing stock here is different. A gas fireplace in a 1920s colonial on Locust Street was likely retrofitted into a chimney originally built for a coal stove. That means venting paths that don’t always match what a modern direct-vent unit needs. Ruben Castellano leads our team with a simple rule: nothing gets recommended unless the homeowner can see the problem with their own eyes on a camera screen. That’s a promise we’ve held to on every job in Lockport, and it’s the reason local homeowners call us back when the next issue shows up. Every technician who comes to your door is background-checked, identity-verified, uniformed, and announced by name and photo before the visit through our Threshold Standard process. And every call to (336) 863-3889 is answered by a live person, any hour.
Our work in Lockport carries the 365-Day Done Right Promise. If a repair we make fails within a year, the second visit is free. That guarantee is written, not spoken. It’s the same guarantee we apply to gas fireplace repair in Lockport and every other city we serve.
Our Gas Fireplace Repair Services in Lockport
Here’s what we actually do when we come to your Lockport home. We carry professional trade materials, we show you the evidence, and we explain everything before you pay a dollar.
Gas Fireplace Repair
Most gas fireplace problems in Lockport boil down to a handful of causes: a failed thermocouple or thermopile, a clogged burner, a bad gas valve, or a venting problem that’s letting combustion gases sit where they shouldn’t. We diagnose all of these with a camera inspection and a combustion test. On a recent service call to a pre-1900 two-story on Market Street in the historic downtown grid, the homeowner had been told by another company that she needed a full reline. Our camera showed the original clay-tile flue was intact. The real problem was a failed damper gasket and a blocked cap screen. We replaced the gasket, cleaned the cap, and verified proper venting. The fix was under $200. The reline would have been thousands.
Level 2 Inspection
Lockport’s older homes need a Level 2 inspection any time a gas appliance is installed, a chimney system has been damaged, or a home is bought or sold. A Level 2 inspection includes everything in a Level 1 sweep plus camera scanning of the entire flue interior. In a city with this many pre-1920 chimneys, the camera catches what a flashlight never will: cracked clay tiles, voids in mortar, and improper connections from retrofitted gas fireplaces. If your fireplace was installed before you bought the house, get a Level 2 inspection before your first cold night.
Chimney Relining
A gas fireplace vented into an unlined or clay-tile flue never designed for direct-vent appliances creates condensation inside the chimney. That moisture soaks into the masonry, breaks down mortar joints, and in the worst case can allow carbon monoxide to seep back into the living space. We install professional relining systems from Olympia Chimney and DuraFlex, not box-store substitutes. But here’s the thing we tell every Lockport homeowner: a reline is a big-ticket repair, and we will not recommend one without camera evidence you can see for yourself. If the flue is intact, we’ll tell you to save your money.

Trusted Brands We Service in Lockport
We install and service components from Olympia Chimney, Copperfield, and Famco, which are the same brands chimney professionals specify, not the improvised substitutes you’ll find on a big-box shelf. Because we stock local parts for common Lockport applications, turnarounds for typical repairs like thermocouples, gas valves, and cap screens are fast. You won’t wait weeks for a part to ship from out of state. If it’s a genuine gas fireplace repair, our Gas Fireplace Repair team handles everything from the burner up.
Common Gas Fireplace Repair Problems We See in Lockport Homes
- Poor draft and a faint gas smell when the fireplace runs. In Lockport’s older frame homes, the chimney cap screens clog with lake-effect debris and the flue fills with nested material from birds, restricting draft. The smell is combustion gas not exiting properly. A blocked cap is a common fix, but you need a camera to confirm the flue isn’t also compromised.
- Flaking or peeling stone on the interior or exterior chimney face. Medina sandstone soaks up moisture, and repeated wet-freeze stress makes it spall in sheets. This isn’t cosmetic. Where stone delaminates, the chimney crown and flashing fail next, and water reaches the gas fireplace firebox.
- Condensation inside a chimney originally built for wood or coal. When a modern gas fireplace vents into an unlined flue, the combustion gases are relatively cool. They condense inside the chimney. That moisture eats at mortar joints from the inside, and the damage is invisible without a camera scan.
- Hard mortar patches that crack again in a year or two. We see this constantly in Lockport’s older chimneys. Someone repointed with Portland-rich mortar, which is too rigid for porous stone. It traps moisture and accelerates spalling. The correct fix is a softer lime-based mortar, matched to the stone’s movement.

FAQs – Gas Fireplace Repair in Lockport
Poor draft and an odd smell usually mean the flue is partially blocked or the venting path doesn’t match what your direct-vent fireplace needs. In Lockport’s older homes, that often traces to a clogged cap screen or a gas fireplace vented into a clay-tile flue originally built for wood or coal. The fix starts with a camera inspection to see exactly what’s happening. Call (336) 863-3889 to schedule an inspection, and we’ll show you the screen before we recommend anything.
No, not automatically. Flaking Medina sandstone or Niagara limestone on a Lockport chimney face is a spalling problem driven by moisture and freeze-thaw cycles, not a sign that the flue liner has failed. A full reline only makes sense if the camera shows cracked tiles, voids, or an improperly sized flue. If the flue is intact, the correct repair is repointing with a lime-based mortar matched to the stone. We’ll prove it with camera footage before we ask you to spend a dollar.
Once a year, before burning season. Lockport’s lake-effect snow bands and fluctuating winter temperatures put more freeze-thaw stress on chimney masonry than most of Western New York, so spring and fall inspections are your best defense against crown cracks and water intrusion. If your fireplace is new to you, schedule a Level 2 inspection once before your first season of use. Call (336) 863-3889 and we’ll get it on the calendar.
First-degree creosote is a loose, flaky soot that brushes off easily. Third-degree creosote is a hardened, tar-like glaze that requires mechanical or chemical removal. Gas fireplaces produce little to no creosote because the fuel burns clean, so if someone is telling you that your gas fireplace needs creosote removal, that’s a red flag. The real concerns for gas units are venting, gas pressure, and combustion safety. Let our camera inspection verify what’s actually happening before you agree to anything.
Yes, and that’s the core of how we operate in Lockport. We will not recommend a repair, replacement, or reline without camera evidence you can see for yourself. If the job can wait, we’ll say so. If a cheaper fix solves the problem, we’ll quote the cheaper fix. Our written guarantee covers every repair for a full year, and if it fails, the second visit is free. Call (336) 863-3889 for a straight answer.
