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.

AfterGelco Chimney Liner & Rebuild in Flushing: What to Know First
Gelco chimney liner and rebuild work in Flushing typically runs $1,850 to $4,200 for liner replacement and $3,800 to $11,000 for partial or full rebuilds, with most jobs completed in one to two days. We’re an independent Gelco service provider, not a factory-authorized shop, which means we quote the repair honestly whether it calls for OEM parts or a smarter aftermarket fix. If you own a Gelco liner or a Gelco-built chimney system and something’s failing, call (516) 240-9191 and we’ll put a camera down the flue before anyone quotes you a dollar.
How Gelco Products Fail - and How We Fix Them
- Gelco Flexible Stainless Liners, the 316L series: We see these in Flushing homes where the original clay tile liner cracked and a Gelco flex liner went in as the fix. The weak point is rarely the steel itself. It’s the connection at the top plate and the tee at the base. Flushing’s freeze-thaw cycles work the top plate loose over five to eight years, then rain gets behind it and rusts the collar. We remove the old plate, inspect the liner crown, and reset everything with a water-tight seal. If the liner body is sound, you don’t need a new liner. You need a new top assembly.
- Gelco Rigid Stainless Liners in older attached colonials near Flushing Town Hall: These liners fail at the joints first. Rigid sections are joined with pop rivets and sealed, and after a decade of heating and cooling, the sealant degrades and the joints start to separate. The symptom is usually a faint smoky smell in the house on windy days. We pull the camera through to find the exact joint, then either re-seal or replace the section depending on what the footage shows.
- Gelco Cast-in-Place Liners (the pour-in-place series): Flushing has a lot of pre-1950s chimneys with irregular flue dimensions. Gelco’s cast-in-place system gets specified for those because it forms to the existing flue. The failure mode we document most is thickness inconsistency. If the original pour wasn’t mixed right or the form shifted, you get thin spots that spall under heat. Spalling means the liner surface flakes or crumbles. We identify thin spots by camera and sound, then sleeve the flue with a correctly sized stainless liner rather than trying to patch a pour that was never even.
- Gelco chimney crowns rebuilt with their pre-cast crown forms: We get calls for crown rebuilds where a Gelco crown was installed but the mortar bed underneath wasn’t sloped. Water pools instead of shedding, then freezes, and the crown cracks within three winters. Flushing’s winters are wet and cold enough to make this a predictable failure. Our rebuild involves removing the old crown, re-laying the brick corbel if needed, and pouring a new crown with a proper 2-inch overhang and drip edge.
- Gelco dampers and transition plates: The throat damper on older Gelco system installs is often a cast-iron butterfly damper that rusts open or seizes closed. When a homeowner reports cold air dropping down the chimney in winter or difficulty getting a fire started, we inspect the damper first. Replacement is straightforward, and we always photograph the old damper before removal so you can see exactly why it failed.
Our Gelco Chimney Liner & Rebuild Process
- 1
Call and book: A live person answers at (516) 240-9191. We schedule a visit and send a text when the tech is on the way.
- 2
Camera inspection first: We run an NFPA 211 Level 2 camera scan down the entire flue. You watch the footage with us. Corrine Halstead’s rule is simple: no quote without evidence. The camera doesn’t negotiate – it just shows you what’s there.
- 3
Parts decision: If the Gelco liner needs replacement, we evaluate whether OEM Gelco parts make sense or whether a DuraFlex or HeatShield equivalent performs better for less. We tell you the trade-offs in plain terms and let you decide with the numbers in front of you.
- 4
Written scope and price: Before any work starts, you get a written scope, a written price, and a written warranty. This is Haven Standard Clause 1: H.A.V.E.N. – Have it in writing. No verbal quotes, no surprises after the fact.
- 5
The repair or rebuild: Our crew does the liner replacement, partial rebuild, or full rebuild, including any masonry work. We protect your home with drop cloths and clean up daily.
- 6
Photo record and test: We run the camera again after the work is done, perform a draft test, and hand you a documented photo record showing the finished liner or rebuild from top to bottom. You walk away with evidence, not just a receipt.

Our techs are background-checked, uniformed, and trained specifically on Gelco systems plus the other brands we service: DuraFlex and HeatShield. If a Gelco part is on backorder or costs more than an equivalent aftermarket alternative, we’ll tell you. You get the footage, the written quote, the written warranty, and a 365-Day Done Right Promise stamped on every job. If it’s not done right, we make it right. No fine print.
FAQs
If we install a non-Gelco liner like DuraFlex or HeatShield, it doesn’t void a warranty on your remaining Gelco components, but it means the new liner has its own manufacturer warranty separate from Gelco’s. We’ll spell out exactly what’s covered by whom before you approve anything.
The camera footage tells you. We show you the scan and point to the specific issue: a rusted top collar, a separated joint, a crack in the liner body, or nothing wrong at all. If the liner is structurally sound and only the top plate is failing, you pay $350 to $600 instead of $2,000.
We typically schedule inspections within a few days and complete most liner replacements in one day, with rebuilds taking one to two days depending on weather and access. Call (516) 240-9191 to get on the schedule and we’ll text you the exact arrival window.
You get a before-and-after photo record from the camera scan, the written scope, the written warranty, and our 365-Day Done Right Promise in writing. Haven Standard Clause 4 requires the photo record on every job, and we’ve been doing it since 2009.
Yes. If you want OEM Gelco components and they’re available, we’ll source and install them. We’ll also tell you if an aftermarket part from DuraFlex or HeatShield performs the same for less money, then let you decide. No pressure either way.
