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.

AfterOlympia Chimney Flue Liner Replacement: The Hempstead Owner’s Guide
We stock and install Olympia Chimney-compatible flue liner replacements throughout Hempstead, with most jobs running between $1,800 and $3,400 installed depending on the liner diameter, height, and whether insulation is needed. Most Hempstead homes we service run 6-inch round stainless liners in masonry chimneys, and we carry Olympia Chimney’s 316L alloy rigid and flex options plus equivalent DuraFlex and HeatShield stock on the truck. You’ll usually know before we do: the liner looks fine from the top, but the boiler or water heater starts drafting poorly, or you notice flaking metal and rust in the cleanout. Sometimes it’s condensation eating the liner from the inside out, which is the most common failure mode in Nassau County’s salt air.
Which Olympia Chimney Models This Applies To
Olympia Chimney has been manufacturing liner systems for years, and most homeowners in Hempstead are working with their 316L stainless flex or rigid liner kits, which come in diameters from 4 inches up to 12 inches. The gotcha we see constantly: Olympia Chimney’s flex liners are built to their own crimp and coupling spec, so a no-name fitting from a big-box shelf won’t always seat right. When we show up, we measure the old liner’s inside diameter and check the appliance collar before matching it to Olympia Chimney’s sizing chart or a DuraFlex equivalent if the original is discontinued. If your liner still has its label near the top, that’s the fastest route to a correct match. If it’s corroded past reading, we measure and go from there.
Wendell Pike will tell you the same thing he tells every Hempstead homeowner: the liner’s job is to carry exhaust and protect the masonry, and the wrong size is worse than no liner at all.
Signs Your Olympia Chimney Flue Liner Replacement Is Failing
- Flaking rust in the firebox or cleanout. Stainless liners corrode from the inside when condensation mixes with flue gases. By the time you see flakes, the liner wall is thinning and likely perforated in spots.
- The water heater or boiler drafts weak and smells. A liner riddled with pinholes leaks flue gas into the chimney chase instead of carrying it up and out. Rooms near the chimney may smell faintly of exhaust on humid days.
- White or green staining on the chimney exterior. Condensation migrating through a failed liner shows up as efflorescence or staining on brick. In Hempstead’s freeze-thaw cycles, that trapped moisture spalls brick faces within a few winters.
- You see daylight through the liner seam. Shine a flashlight down from the top cap. If light bleeds through seams or pinholes, the liner has lost structural integrity and needs replacement, not patching.
- The old liner pulls apart in your hands during cleaning. Our sweeps see this a few times each season in Hempstead. Once the crimps let go, the liner is done, and sweep pressure alone can finish it.
Replacement Cost & What’s Included
In Hempstead, an Olympia Chimney-compatible flue liner replacement typically runs $1,800 to $3,400 installed. The spread comes down to three things: liner length (a two-story chimney takes 25 to 35 feet, a ranch often 15 to 20), whether the existing liner comes out clean or needs to be chipped free of old mortar, and whether you need insulation wrap, which we recommend on exterior chimneys because it keeps flue gases warm enough to draft and cuts condensation. The price you hear over the phone is the price on the invoice. No add-ons after we start pulling tile, no surprise line items. Every Hempstead liner replacement is backed by our 90-Day Done Right Promise in writing. If the liner isn’t drafting correctly or the installation isn’t right, one call brings us back at no charge.
DIY or Call Us?
An owner can safely check the cleanout door for flaking metal, shine a flashlight up from the bottom, and look at the chimney cap for rust streaks. That’s where safe DIY ends. Dropping a 35-foot flex liner down a Hempstead chimney requires roof work, lifting the cap, pulling the old liner, and often working around power lines and steep pitches. The liner itself is stiff, heavy, and wants to kink. If a seam catches on a tile edge and you force it, you’ll tear the liner and be out the cost of the part. We’d rather you save the hospital bill. Call (516) 963-1068 and we’ll do it right the first time.
FAQs
A 316L stainless liner in Hempstead typically lasts 15 to 25 years, less if the chimney runs an oil-fired boiler without annual sweeping. Condensation from oil exhaust is more corrosive than gas, and untreated it cuts liner life by a decade.
Small pinholes can sometimes be sealed with a resurfacing product like HeatShield, but once a liner is perforated or structurally weak, patching is temporary. We won’t recommend a patch if the liner is too far gone to hold one. Call (516) 963-1068 for an honest assessment.
Most Hempstead liner replacements take 4 to 6 hours on site. That includes removing the old liner, prepping the flue, installing and insulating the new one, reconnecting the appliance, and a camera inspection before we pack up. Bigger jobs in older masonry chimneys can push into a second morning.
We keep common 6-inch and 8-inch Olympia Chimney-compatible 316L liners on the truck, along with DuraFlex and HeatShield equivalents in standard lengths. Odd sizes or longer runs may take a day or two to have staged. When you call, we’ll tell you honestly whether the part for your specific Hempstead chimney is already on hand.
