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.

Our Chimney Cleaning & Sweep Services in Hempstead
Level 1 Inspection
A Level 1 inspection is the standard check that happens alongside your annual sweep. For most Hempstead homes, this means examining the accessible portions of the flue, the firebox, the damper, and the exterior chimney from the ground or roof. If your home still vents the same appliance it was built with and you’re on a regular sweeping schedule, this is usually all you need. But many Hempstead houses have never had even this done, and we routinely find problems on a first Level 1 that were hiding in plain sight.
Level 2 Inspection
Here’s the one that matters in Hempstead. A Level 2 inspection uses a camera to scope the entire flue from top to bottom, and it is the only way to see what acidic gas exhaust has done to a clay tile liner that was never designed for it. If you converted from oil to gas, bought the house, or haven’t had a camera in the flue before, this is where we start. Nothing gets recommended without camera footage you can watch yourself. The camera footage and a plain-English verdict, every time, no exceptions.
Creosote Removal
Creosote builds up differently depending on what and how you burn. First-degree creosote is a brush job. Third-degree is a glaze that hardens onto the flue wall and will not come off with standard sweeping. In Hempstead fireplaces that get used heavily each winter, we often find second-degree creosote that requires rotary cleaning tools. We’ll tell you what degree you have, what it means, and whether a straight sweep handles it or the flue needs mechanical removal. Most Hempstead creosote removal jobs run $250-$450 when the buildup is beyond a standard sweep.
Soot Removal
Soot is the fine black powder left behind by wood fires, and it’s lighter and easier to remove than creosote. That said, soot inside a flue that is already spalling or cracked still means gas and heat are moving through a compromised channel. We remove the soot, then we look at what it was sitting on. A soot removal in Hempstead typically adds $50-$100 to a standard sweep when it’s concentrated in the firebox and damper area.

Trusted Brands We Service in Hempstead
We install and service liners and components from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. We keep common liner and cap parts in stock for the housing stock we see across Hempstead, which means we’re not waiting a week for a shipment when your liner needs to be pulled and replaced. The DuraFlex liner system gets specified on most Hempstead oil-to-gas retrofits because it’s sized correctly for the appliance, not for the old clay tile it’s replacing. Gelco and HeatShield products come up regularly when we’re repairing fireboxes and parging smoke chambers in mid-century fireplaces.
Common Chimney Cleaning & Sweep Problems We See in Hempstead Homes
- Oversized clay flues on oil-to-gas conversions. This is the Hempstead signature. The original flue was built for a No. 2 fuel oil burner that ran hot and wide open. The modern 80-90% efficient gas furnace vents much cooler, smaller-volume exhaust. That exhaust stalls inside the oversized clay tile, condenses, and turns acidic. The acid eats the clay from the inside. A camera inspection is the only way to see it.
- Salt-air mortar erosion from the Atlantic. Hempstead sits roughly 8-10 miles from Jones Beach, and the salt-laden air that reaches these neighborhoods accelerates mortar joint erosion and brick spalling on the chimney crown and upper courses. Chimneys here deteriorate faster on the outside than more inland Long Island towns, and homeowners often mistake it for cosmetic wear until water gets behind the brick.
- Original single-wythe brick chimneys with no clay liner at all. Some of the oldest Cape Cods in Hempstead were built before liners became standard code, or the original clay liner has cracked so severely it’s no longer functioning. Creosote and flue gases leak into wall cavities through those cracks. A basic cleaning will not fix that, and burning in that condition is a fire and carbon monoxide risk.
- Unused fireplaces that have been ignored for decades. Once a year, burn or no burn. Chimneys break in the off-season too. Water gets in through deteriorated crowns and freeze-thaw cycles from nor’easters widen the cracks. By the time the fireplace gets lit again, the flue is in worse shape than the last time it was used. An annual sweep and inspection catches it before it becomes a liner replacement or a chimney rebuild.
Pricing for Chimney Cleaning & Sweep in Hempstead, NY

FAQs - Chimney Cleaning & Sweep in Hempstead
Because the housing stock was built for oil heat and most of it now vents gas through clay liners that were never designed for that appliance. The flue is oversized, the exhaust condenses, and the acid eats the clay from the inside where you can’t see it. A Level 2 camera inspection is the only way to know whether the flue is sound before we sweep it. If the liner is already spalling, a brush can knock loose the last of it and leave you with a hole you didn’t know you had. We camera first, then clean. Call (516) 968-5380 to schedule a Level 2 inspection in Hempstead.
Yes, it does. Salt-laden Atlantic air accelerates mortar joint erosion and brick spalling on the Hempstead Chimney Cap & Crown, and Hempstead’s nor’easters drive freeze-thaw cycles that widen the cracks every winter. We see chimneys here need pointing and crown repairs years before equivalent homes further north on the island. If your mortar joints are sanding away or you see brick faces popping off, that’s the salt air doing its work, not just age. Call (516) 968-5380 and we’ll take a look.
You should have a camera scoped to see what the acidic condensate has done to the inside of your clay tile flue. This is the single most common failure we diagnose in Hempstead’s 1945-1965 housing stock, and it’s invisible from the outside. If the liner is glazed, spalling, or partially collapsed, the fix is a properly sized replacement liner, usually DuraFlex. If it’s intact, a standard sweep and inspection keeps you on schedule. We’ll show you the footage either way. Call (516) 968-5380 for a Level 2 inspection quote in Hempstead.
First-degree creosote is a soft, flaky soot-like coating that a standard brush removes cleanly. Third-degree creosote is a hard, glossy glaze that has baked onto the flue wall and will not come off with brushing, it requires rotary removal or chemical treatment. Most active fireplaces in Hempstead fall somewhere in the second-degree range by spring. The degree matters because it changes the cost and the method. We’ll tell you exactly what you have before we touch a brush. Call (516) 968-5380 for a sweep and honest assessment.
Yes. Water and freeze-thaw cycles damage unused chimneys just as much as fires damage used ones, and in Hempstead’s salt air the crown and upper courses deteriorate faster. If the chimney vents a furnace or boiler, the flue is in use year-round even when the fireplace is not. An annual sweep and inspection, burn or no burn, is the cheapest way to catch a problem before it’s a $4,000 liner or a masonry rebuild. Call (516) 968-5380 and we’ll get you on the schedule.
