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.
Fast, Reliable Chimney Sweep Across Lockport
A standard chimney sweep in Lockport runs $189 – $289, and most jobs take 45 to 90 minutes from setup to final vacuum.

Why Alcott Chimney Sweep Is Lockport’s Preferred Chimney Sweep Company
We’ve worked enough Lockport chimneys to know what the Erie Canal building boom left behind. The pre-1900 homes along Market Street, Locust Street, and the streets off Main have stacks built from stone quarried right here, not brick shipped in from elsewhere. That matters when you’re deciding whether a flue is safe or needs work. Local experience means we don’t guess at what we’re seeing. Ruben Castellano built this company on a simple rule: show the homeowner the evidence before recommending anything. Every technician who knocks on a door in Lockport is background-checked, identity-verified, uniformed, and announced to you by name and photo before arrival. That’s the Threshold Standard, and it’s not optional. You’ll know exactly who is coming before the truck pulls up.
Our 365-Day Done Right Promise backs every job. If a repair we make fails within a year, the second visit is free. Written price before work begins. Written guarantee on every repair, included at no extra charge. No exceptions, no fine print.
Fireplace Cleaning in Lockport
Fireplace Cleaning in Lockport is seasonal work in the truest sense. The lake-effect bands off Lake Ontario push hard through Niagara County from November into March, and a fireplace that worked fine in October can be drawing poorly by January because creosote – the tar-like buildup that causes chimney fires – has layered onto the flue walls. A standard fireplace cleaning here runs $189 – $289 and includes the firebox, smoke shelf, damper assembly, and full flue brushing.
Creosote Removal
Lockport’s older fireboxes burn cooler than modern inserts, and that means creosote builds faster. First-degree creosote is flaky and brushes out easily. Third-degree is a hard, glossy glaze that requires rotary tools and more time, which pushes cost toward the higher end of the range. We’ll show you what’s in your flue before we start, and again when we finish.
Soot Removal
Soot is softer than creosote and usually a sign of incomplete combustion rather than imminent fire risk. That said, a heavy soot load left through a wet Lockport spring can absorb moisture and corrode clay tile liners from the inside. We remove it as part of every cleaning, not as an add-on.
Chimney Services in Lockport
Chimney Services in Lockport go well beyond the brush. The stone chimneys on 1840s – 1920s homes need eyes on the mortar joints, crown, flashing, and the flue liner itself. We offer Level 1 inspections as part of every sweep, and full Level 2 camera inspections when we need to see what’s happening inside a flue that’s been re-vented or is no longer drafting the way it should.
Level 2 Inspection
A Level 2 inspection runs $249 – $399 in Lockport and includes a camera run down the entire flue length. You watch the monitor in real time. That’s the point. If someone recommends a reline, you see the crack, the gap, or the deteriorated tile with your own eyes. Nothing gets recommended on a hunch.

Annual Sweep
NFPA 211 says chimneys should be inspected at least once a year, and Lockport’s climate argues for doing it in early fall, before the lake-effect snow sets in. An annual sweep catches crown cracks before a full winter of freeze-thaw opens them wider and drives meltwater into soft stone. It’s the cheapest insurance on this page.

Common Chimney Sweep Problems We See in Lockport Homes
- Portland-rich repointing on soft stone. We regularly find Medina sandstone and Niagara limestone chimneys that were repointed years ago with a standard Portland mortar. It’s too rigid for the stone. The joints crack again within a few winters, and the stone sheets off faster than if it had been left alone. We cut it out and repoint with a lime mortar matched to the stone’s porosity.
- Unlined flues quietly venting gas appliances. Many Lockport homes built before 1900 have original flues that were never lined or were lined with clay tile generations ago. Somewhere along the way, a gas furnace or water heater got vented into a stack that was never sized for it. The result is weak draft, condensation inside the flue, and acidic damage to the mortar. A camera inspection tells you exactly what’s happening.
- Crowns and flashing left open through refreeze cycles. Lake Ontario snow piles onto chimney crowns, melts in a January warm-up, refreezes that night, and the cycle repeats all winter. Cracks in the crown or gaps in the flashing become water paths that rot the mortar joints and spall the stone face. This is the most common repair need we find in Lockport, and the one most often missed by a visual-only sweep.
- Delaminating Medina sandstone faces. The red stone on many older Lockport chimneys is beautiful when it’s sound, and it fails in a specific way: sheets separate from the face and peel off. That’s freeze-thaw working on the stone’s natural porosity. It looks alarming, and sometimes it is. It can also be stabilized early with the right mortar work. We’ll tell you plainly which situation you have.

FAQs About Chimney Sweep in Lockport
A visual sweep is enough for an annual cleaning, but if anyone recommends a liner replacement, a camera inspection is non-negotiable – and you should watch the footage yourself. In Lockport specifically, older homes with clay tile flues and re-vented gas appliances often get upsold into full relines they don’t need. We never recommend a reline without camera evidence you can see. Call (336) 863-3889 and we’ll explain exactly what a Level 2 inspection covers before you book.
Because Lockport’s older chimneys are built from Medina sandstone and Niagara limestone, which are softer and more porous than fired brick. Standard Portland mortar is harder than the stone itself, so when water freezes and the assembly moves, the mortar stays rigid and the stone cracks. A lime mortar flexes with the stone and lets moisture breathe out instead of trapping it. Using the wrong mix here accelerates the exact failure it’s supposed to fix.
You’ll see thin sheets of stone peeling away from the face, often with a hollow sound when tapped, and sand-like grit collecting at the base of the chimney or in the gutter below. On Medina red sandstone, the delaminated sheets sometimes show a lighter color underneath. It’s a progressive problem, not a sudden one, and catching it early means repointing and sealing instead of rebuilding. If you see this on your chimney, call (336) 863-3889 for an honest assessment.
NFPA 211 says every chimney should be inspected at least once per year, and we recommend Lockport homeowners do that inspection in early fall before lake-effect season begins. The freeze-thaw cycles here are more frequent and intense than in Buffalo, which pulls primarily from Lake Erie, and that stress lands hardest on crowns, flashing, and lime mortar joints. An annual inspection catches small failures before a winter of meltwater turns them into rebuilds.
First-degree creosote is flaky and dusty, and it brushes out with standard sweeping tools. Third-degree is a shiny, tar-like glaze that has baked onto the flue wall and cannot be removed with a brush alone; it requires rotary chains or chemical treatment and costs more. In Lockport’s older fireplaces, which tend to burn cooler than modern inserts, third-degree buildup is common by mid-winter. We’ll show you what’s in your flue and tell you plainly what it will take to remove it.
