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 Franklin Square
If you’re searching for a chimney sweep in Franklin Square, the short answer is this: a standard sweeping for a wood-burning fireplace runs $189 to $289 in this area, and a sweep with a Level 1 inspection typically lands between $249 and $389. Most Franklin Square homes we visit need more than a quick brush-out.

Why Alcott Chimney Queens Is Franklin Square’s Preferred Chimney Sweep Company
Franklin Square homeowners call us because we show our work before, during, and after the job. You’ll know the technician’s name and see their photo before we arrive. That person shows up in uniform, badge visible, and hands you a written price before any work starts. Ruben Castellano built Alcott Chimney Sweep on a simple rule: never recommend a repair you can’t prove with a camera. That matters in Franklin Square, where the split-levels and ranches off Hempstead Turnpike hide decades of oil-to-gas conversions and abandoned flues. Our Chimney Sweep team has pulled soaked squirrel nests, corroded dampers, and three-foot runs of first-degree creosote from chimneys that looked fine from the outside. Every technician passes a background check and identity verification under the Threshold Standard before stepping onto your property. That’s not an upgrade. It’s how we hire.
We’ve worked on capes near Washington Street, ranches off Franklin Avenue, and split-levels north of Hempstead Turnpike. Dispatch and scheduling are coordinated from our New York City office, and crews serve Franklin Square locally. When you book, you get a real window and a real person to call if plans change. Since 2002, Alcott has operated as part of the Threshold Group family. The 365-Day Done Right Promise covers every completed job: if a repair fails within a year, the second visit is free. Written, signed, and included.

Chimney Maintenance in Franklin Square
Chimney Maintenance in Franklin Square means dealing with what salt air, freeze-thaw cycles, and a converted oil furnace leave behind. A mid-century masonry chimney here isn’t a set-it-and-forget-it feature. It’s a system with joints, crowns, caps, and flues that fail in predictable ways under Long Island weather. Basic maintenance includes a visual check of the crown and flashing, testing the damper, checking for loose brick or spalling mortar, and confirming the flue is clear and drafting correctly. For most Franklin Square homes, we recommend an annual maintenance visit before the first cold snap. A maintenance visit with a sweep runs $249 to $389, depending on flue count and access.
Crown and Flashing Check
Atlantic salt air eats mortar faster than most homeowners expect. A crown with hairline cracks lets water behind the brick, and freeze-thaw does the rest. We check for spalling at the roofline, rusted flashing, and damp spots in the attic chase. Small crown repairs now beat a torn-apart chimney in March.
Damper and Cap Inspection
A stuck damper or missing cap on an unused flue means rain, squirrels, and debris. In Franklin Square, the biggest single failure we see is an abandoned oil flue that was never capped after a gas conversion. We seal and cap those correctly so they draft the way they should, or stay sealed if they’re no longer in use.
Chimney Sweep Services in Franklin Square
Chimney Sweep Services in Franklin Square start with an honest look at what’s actually burning in your firebox. Wood stoves used as primary heat produce far heavier creosote loading than a fireplace lit a few times a season. That changes the safe sweeping interval. If you’re running a wood stove daily from November through March, you need a sweep every 60 to 90 days, not once a year. A standard sweep on a wood-burning fireplace is $189 to $289. A wood stove sweep with a Level 1 inspection runs $249 to $389. Both include a camera report you can see for yourself.
Creosote Removal
Creosote is the tar-like residue that condenses on flue walls when smoke cools too fast. First-degree creosote brushes out. Third-degree is glaze that requires mechanical removal. We’re honest about the difference and show you photos of both. If you’re burning wet coastal wood, creosote builds faster, plain and simple.

Annual Sweep
For fireplace users in Franklin Square, one sweep per year before the burning season is the baseline. But “annual” means something different for a wood stove as primary heat. During a quote call, we’ll ask how many cords you burn and how often. That answer tells us the right interval, not a calendar date.

Trusted Brands We Service in Franklin Square
We install and service what we’d put in our own chimneys. DuraFlex liner systems hold up against the corrosive byproducts of oil and gas exhaust better than cheap knockoffs. HeatShield resurfacing lets us restore a flue without ripping out masonry, which is often the right call on a 1950s split-level where the brick is structurally fine but the clay liner is cracked. We also work with Gelco caps and Olympia Chimney components. Local parts availability matters. If a Franklin Square customer needs a cap or a damper replaced, we don’t make you wait three weeks on a backorder from a distributor we’ve never met.
Common Chimney Sweep Problems We See in Franklin Square Homes
- Uncapped oil flue after gas conversion. The oil furnace goes, the gas boiler comes in, and nobody caps the orphaned flue. Rain gets in, squirrels nest, dampers rust, and the fireplace flue drafts poorly because the system now has an open bypass. We cap it and seal it.
- Creosote glaze from wet coastal wood. Salt-laden Atlantic air means firewood here never fully seasons the way it does inland. Wet wood burns cool, smoke condenses fast, and glaze forms on flue walls. Heavier creosote means a shorter safe sweeping interval.
- Freeze-thaw damage to crowns and flashing. Franklin Square winters hover around the freeze line all season. Water works into hairline cracks, freezes, expands, and pops mortar loose. By spring, you’ve got spalled brick and a leak behind the walls.
- Blocked draft from abandoned flue debris. An unused flue that was never capped collects leaves, nests, and dead animals. When you finally light a fire in the adjacent flue, draft suffers because the chimney is drawing through a clogged bypass. We clean both flues, not just the one you use.

FAQs About Chimney Sweep in Franklin Square
Every 60 to 90 days during the burning season. A wood stove run daily from November through March builds creosote far faster than a fireplace lit on weekends. Franklin Square’s wet coastal wood makes it worse: the fuel never fully seasons, so it burns cooler and condenses more tar onto flue walls. If you’re burning three to five cords a season, plan on three sweeps. Call (518) 719-4643 and we’ll help you set a schedule that matches your actual burn rate, not a guess.
The dual-flue setup comes from the original build: one flue for the oil furnace, one for the living-room fireplace. When the oil furnace was swapped for gas, many contractors left the oil flue open and uncapped. An uncapped flue lets rain, squirrels, and debris into the system, which corrodes the damper and blocks draft for the fireplace flue. If the flue is no longer in use, it should be sealed at the top with a proper cap and at the bottom to keep air and moisture out. If it still vents something, it needs a cap sized for its diameter and fuel type. A quick camera inspection tells us which path you’re on.
Yes, and it’s not subtle. Salt accelerates mortar deterioration, especially on crowns and exposed brick at the roofline. Combined with freeze-thaw cycles that put Franklin Square right around the freezing line all winter, hairline cracks turn into spalling brick and leaks behind attic walls within a few seasons. Homes closer to the water see this faster than those further inland, but the whole area deals with it. Regular crown checks and resealing are the cheapest way to avoid a full masonry rebuild.
Glaze, almost always from burning wet or partially seasoned wood. Franklin Square’s humidity and coastal air make it harder to season firewood down to the 20% moisture content a clean burn needs. Wet wood smolders, the smoke cools too fast, and the creosote condenses as a hard, shiny glaze that won’t brush out. Removing it takes mechanical tools and sometimes a chemical treatment. The honest fix is better firewood and a shorter sweeping interval. Get the glaze removed now, then we’ll help you sort out your wood supply before next season.
Yes, as long as the oil flue is fully abandoned and no longer venting any appliance. The cap seals the top against rain and animals without interfering with anything, because nothing is exhausting through that flue anymore. If the flue still serves the gas furnace or water heater, a different cap is required, one sized to maintain proper draft and clearances. We inspect the system before recommending anything. On a split-level off Hempstead Turnpike, we did exactly this: swept a two-flue masonry chimney where the oil-furnace flue had been abandoned but never capped, pulled a soaked squirrel nest and three feet of first-degree creosote from the fireplace flue, installed a Copperfield cap on the orphaned flue, and sealed the crown to stop the water entry that was spalling the brick at the roofline.
