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 Great Neck
A standard chimney sweep in Great Neck typically runs $189 – $289 before any repairs, and most homes are done in about an hour. The coastal air here changes the math though. Salt from Long Island Sound settles into mortar joints and flue tiles, making creosote stick harder and corroding metal components years ahead of schedule. Our Chimney Sweep team works across Great Neck regularly, from the Tudors off Middle Neck Road to the Colonials near the LIRR stations. Call (518) 719-4643 for a written quote before we ever start.
Why Alcott Chimney Queens Is Great Neck’s Preferred Chimney Sweep Company
Since 2002, Alcott Chimney Queens has built a reputation in Great Neck on one thing: showing up as the person we said we’d send. Ruben Castellano made that the rule from day one. You get the technician’s name and photo before the truck rolls, and that technician shows you a photo ID badge at your door. No guessing who’s walking up the driveway.
Great Neck homeowners call us because we understand what these houses are. A 1920s Colonial in Kensington has a different flue system than a 1950s split-level near the Village of Great Neck plaza. Our techs know both. We’re part of the Threshold Group family, and every tech passes a background check and identity verification before they ever set foot on your property. That’s the Threshold Standard, and it’s never optional.
When you schedule with us, you get a written price before any work begins. Not a verbal estimate that changes. A line item price on paper. And every repair we do carries a written guarantee. If it fails within 365 days, we come back and fix it free. That’s the Done Right Promise, and it applies to every job in Great Neck.
Styles & brands we work with





Gas Fireplace Cleaning in Great Neck
Gas Fireplace Cleaning in Great Neck matters more than people expect, because the coastal humidity gets into gas logs and burner assemblies and accelerates rust and soot accumulation on the ceramic components. A gas fireplace that burns yellow or leaves a film on the glass is telling you something. We see it constantly in homes near the Sound.
A standard gas fireplace cleaning in Great Neck runs $149 – $229, which includes burner inspection, log cleaning, glass cleaning, and a check of the venting from the firebox outward. If the fireplace has never been cleaned in five years or more, plan on a bit more for deep soot removal from the rear panels.
Burner and Vent Inspection
We pull the logs, inspect the burner ports for clogging, and verify the thermopile and thermocouple are reading correctly. Soot buildup on the burner changes the flame pattern and can dump carbon monoxide into the room if the vent is partially blocked.
Glass and Log Restoration
Salt air clouds fireplace glass faster here than inland. We use a ceramic-glass cleaner that removes the haze without scratching, and we reseat the logs to the manufacturer’s original layout so the flame burns the way it was designed to.
Chimney Maintenance in Great Neck
Chimney Maintenance in Great Neck is a different job than it is ten miles inland. The moisture and salt off Little Neck Bay work through mortar joints, crown cracks, and chimney caps year-round. Skipping maintenance here doesn’t just mean more creosote. It means spalling brick faces, rusted dampers, and leaks that rot the roof decking around the chimney chase before you ever see a stain on the ceiling.
A maintenance visit in Great Neck runs $189 – $329 depending on what the flue shows us. That includes the sweep, a Level 1 inspection of the accessible flue and firebox, and a written report with photos. If we find something, you get pictures of it. You don’t take our word for anything.
Cap, Crown, and Flashing Check
These are the first things to fail in a salt-air environment. Galvanized steel caps that would last 15 years in Nassau County’s central areas corrode in 7 – 10 years near the shoreline. Our techs check for rust-through, gaps in the crown sealant, and flashing nails that have pulled loose from the fluctuating humidity.
Smoke Chamber and Damper Service
Older Great Neck chimneys have shallow smoke shelves, which means creosote and soot collect faster and spill back into the room when the wind shifts. We clean the smoke chamber thoroughly and verify the damper opens and seats fully. A sticky damper is a carbon monoxide risk you don’t want to discover in January.
Trusted Brands We Service in Great Neck
We install and service the brands chimney professionals specify, not what’s on sale at a big box store. On the flue and liner side that means DuraFlex stainless liner systems and HeatShield resurfacing for deteriorated flue tiles. For gas fireplaces we carry Gelco and Olympia Chimney parts. For caps, dampers, and flashing we use Famco and Copperfield components. We keep common parts stocked for Great Neck jobs specifically because we know a corroded cap on a Kensington Tudor shouldn’t mean waiting a week for a part to ship from the Midwest. You need a stainless cap, we install it, usually on the same visit.

AfterCommon Chimney Sweep Problems We See in Great Neck Homes
- Salt-accelerated creosote glaze. The humid, salt-laden air off Long Island Sound makes creosote deposits more adhesive and harder to remove than dry, flaky creosote inland. A normal brush often won’t break a second-degree glaze here, and that’s when we bring mechanical rotary tools in.
- Corroded caps and galvanized flashing. Homes within a mile or two of the water go through caps and flashing in about half the time you’d expect. Rust-through lets rain and salt spray drip directly onto the flue tile, and that feeds the creosote problem below.
- Unlined flues in pre-war homes. Many original Great Neck chimneys, especially in Kensington and Russell Gardens, were built without flue liners or with short, cracked clay tiles. Third-degree creosote builds fast in those, and a chimney fire becomes a real possibility if sweeps are skipped.
- Smoke blowback from shallow smoke shelves. Older construction in Great Neck often has shallow smoke shelves and narrow throats. Even after a thorough cleaning, wind off the Sound can push smoke back into the room. We can tell you if a smoke guard or damper adjustment will fix it.

FAQs About Chimney Sweep in Great Neck
Every year, minimum, and more often if you have an unlined flue or burn more than two cords a season. The salt-laden humidity near the Sound makes creosote more adhesive and accelerates corrosion, so an annual check with a sweep is the standard here. If your chimney is in Kensington or Russell Gardens and was built before the 1950s, we often recommend a mid-season visual check. Call (518) 719-4643 and we’ll give you a straight recommendation based on your house and how you burn.
In Great Neck, yes, and sooner than you think. Rust on a cap near the coast means the galvanization is failing, and once it’s breached, salt spray and rain drip directly onto your flue tile. That feeds the exact conditions that cause sticky creosote and flue tile damage. A stainless steel replacement is the right call within a mile or two of the water. We quote it on paper with photos before we replace anything.
That’s second-degree or third-degree creosote glaze, and in Great Neck’s humid coastal air it forms faster and bonds harder than the flaky first-degree creosote you’d get inland. A standard wire brush often won’t remove it. We use rotary cleaning heads with nylon or steel whips to break the glaze without gouging the flue wall. Call (518) 719-4643 to schedule an inspection with photos so you can see exactly what we’re dealing with.
Because many original Kensington chimneys were built with shallow smoke shelves and narrow throats, and some have unlined flues. The geometry of those older systems makes them sensitive to wind pressure off the Sound, and smoke pushes back into the room even when the flue is clean. A smoke guard, a damper adjustment, or in some cases a liner can solve it. We’ll show you the smoke chamber with a camera before we recommend anything.
Not if it’s done right. We use brushes sized to the flue and rotary tools only when the deposit demands it, and we never use chemicals that would eat the mortar on a historic Great Neck chimney. The original brick on a 1920s Colonial is softer than modern brick, so we adjust pressure and technique accordingly. You’ll get photos of the flue before and after so you can see the brick wasn’t harmed.
