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 Plainview: What to Know First
We provide independent Gelco chimney liner and rebuild service in Plainview, with most Gelco liner replacements and partial rebuilds completed in a single visit and priced upfront before any work begins. A typical Gelco stainless steel liner installation in a Plainview colonial runs $2,800-$4,200, while a partial chimney rebuild above the roofline usually falls between $3,500-$6,500 depending on access and brick matching. As an independent Gelco service provider, we carry OEM and quality aftermarket Gelco-compatible parts, and we back every job with our 90-Day Done Right Promise in writing. This page is for Plainview homeowners who know they’ve got Gelco components in their chimney system and want the repair done correctly the first time. Call (934) 348-4832 - a live person answers, 24 hours a day.
How Gelco Products Fail - and How We Fix Them
- Gelco UL-listed stainless steel liners (Model 316Ti and 304 series) develop seam separation at the flex points. In Plainview’s freeze-thaw climate, the expansion and contraction cycles stress the corrugated sections where the liner bends to meet the smoke chamber. We’ve found this especially common in homes south of Old Country Road where 1960s-1980s construction used tighter chimney offsets. We cut back to sound metal, install a custom-fabricated Gelco-compatible transition piece, and pressure-test the joint before we leave.
- Gelco flexible liners in oil-burner applications suffer accelerated corrosion from sulfuric acid condensate. The Model 316Ti flex is rated for solid fuel and gas, but Plainview’s older oil-fired systems running low-temp burns produce wet, acidic flue gas that pools in the corrugations. We don’t just swap the liner; we verify the heating appliance is drafting hot enough, then upgrade to a Gelco 316Ti with increased gauge thickness or transition to a DuraFlex Pro when the duty cycle demands it.
- Gelco rigid liner systems drop at the collar connection after decades of thermal cycling. The male-female slip joint where sections meet can loosen, creating a gap that leaks flue gas into the masonry cavity. Our Level-2 camera inspection catches this before carbon monoxide becomes a problem. We reseat with Gelco-compatible locking bands and refractory sealant rated to 2,000°F, not generic hardware-store silicone that’ll cook off in the first season.
- Gelco liner top plates and rain caps corrode at the mounting points. The stamped-steel top plates on older Gelco installations weren’t always 316Ti throughout; the hardware was often 304 or galvanized. After fifteen to twenty years near the salt air coming off Long Island Sound, we’ve seen the mounting ears rust through completely. We replace with Gelco-compatible 316Ti top assemblies or upgrade to Copperfield custom-fabricated caps when the homeowner wants thirty-year longevity.
- Gelco liner surround insulation settles or degrades, creating hot spots in the masonry. The original vermiculite or ceramic blanket packing can compact over time, especially in Plainview’s clay-heavy soil zones where minor foundation settling transmits to the chimney stack. We remove the old packing, verify the liner is still round and properly supported, then repack with HeatShield Cerfractory Foam or new ceramic blanket to maintain the zero-clearance rating the installation was built to.
Our Gelco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, day or night. We ask what you’re burning, how old the system is, and what symptoms you’re seeing - smoke backup, water intrusion, or a failed inspection report.
- 2
Level-2 camera inspection on arrival. Our technician runs a chimney camera from top to bottom and bottom to top, documenting every flue tile, liner seam, and mortar joint. You see the photos. We give you a plain-English verdict: what’s failed, what’s wearing, and what’s fine to leave alone.
- 3
Parts decision with no pressure. If your Gelco liner can be repaired with OEM components, we quote that. If a quality aftermarket solution from DuraFlex or HeatShield serves your system better for less, we explain the trade-off. The number on the estimate is the number on the invoice.
- 4
Repair or rebuild, single visit when possible. Our background-checked, uniformed technicians carry Gelco-compatible inventory on the truck. Most liner replacements and partial rebuilds finish in one day. Full chimney rebuilds may need a second day for proper curing.
- 5
Pressure test and final documentation. We verify every joint, every seal, every cap. You get photos of the completed work and a written report. Then we sweep up like we were never there.
- 6
The 90-Day Done Right Promise. If anything isn’t right, we come back. In writing, no arguing. That’s the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.
What Gelco Chimney Liner & Rebuild Costs in Plainview
Pricing depends on what your chimney actually needs, not what we hope to sell you.
| Service | Typical Range in Plainview |
|---|---|
| Gelco stainless steel liner replacement (straight run, single flue) | $2,800 - $4,200 |
| Gelco liner replacement with offset/smoke chamber repair | $4,000 - $5,800 |
| Partial chimney rebuild (above roofline, brick match) | $3,500 - $6,500 |
| Full chimney rebuild (to the roofline) | $8,500 - $14,000 |
| Gelco liner repair (seam weld, collar reseat, cap replacement) | $650 - $1,800 |
What moves the price: height and access (steep roofs cost more), whether we need to match discontinued brick from Plainview’s 1960s-1970s building stock, and if the original Gelco installation used non-standard sizing that requires custom fabrication. We don’t recommend anything without camera evidence you can see for yourself, and we’ll tell you straight when work can safely wait another season. Call (934) 348-4832 for a free estimate - we’ll give you an exact number, not a range.
Why Plainview Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been answering the phone with a live person for over 42 years, and Russell Haines has spent the better part of two decades running a brush down chimneys across Long Island, including plenty of homes near the Old Country Road corridor in Plainview. He learned the trade at Los Angeles Trade-Technical College before deciding the East Coast had more fireplaces worth working on, and he’s built a reputation for finding the thing the last guy missed - a cracked flue tile, a damper that only looks like it seals.
Our technicians know Gelco’s product lines because they’ve pulled out enough failed ones to understand where the design stresses concentrate. We don’t push OEM when quality aftermarket from DuraFlex or HeatShield solves the problem more durably. Every job gets photos you can see, a plain-English verdict, and the 90-Day Done Right Promise in writing. If the chimney is doing its job, you won’t think about it once all winter - that’s exactly the point.
FAQs
The original Gelco warranty on most residential liners expired after the stated term, typically 15-20 years from manufacture. As an independent Gelco service provider, our repairs don’t affect any remaining coverage because we’re not altering factory specifications; we’re restoring function with OEM or equivalent components. If your liner is still within the original warranty window, we can document our work to support a claim, though we don’t represent Gelco in that process. Call (934) 348-4832 and we’ll check your installation date against the warranty terms.
Yes. We stock Gelco-compatible 316Ti flex, rigid sections, collars, and top assemblies, and we fabricate custom transitions when factory parts are discontinued. For Plainview’s 1980s-1990s installations with odd diameters or obsolete connection styles, we’ve sourced compatible components from Olympia Chimney and Famco that meet the same UL 1777 listing. We never substitute builder-grade materials. Call (934) 348-4832 - if we can’t get the right part, we won’t take the job.
Repair is viable when the damage is localized - a separated seam, a corroded cap, or a loose collar - and the remaining liner shows clean metal and proper gauge thickness on camera. Full replacement makes sense when corrosion is generalized, multiple seams are failing, or the liner has deformed from a chimney fire or improper fuel switching. We’ll show you both options with photos and honest timelines. Call (934) 348-4832 for a free inspection.
Most straight-run Gelco stainless steel liner replacements in Plainview’s standard colonials finish in four to six hours. Jobs with tight offsets, smoke chamber parging, or exterior masonry repair add time. We book by the job, not the hour, so there’s no clock running while we solve unexpected problems. Call (934) 348-4832 to schedule - we’ll be there when we say.
A failed or leaking liner lets flue gases - including carbon monoxide - escape into wall cavities and living spaces, and it allows creosote to accumulate in the masonry where it can ignite. In Plainview’s older homes with balloon framing, that risk travels fast. The other consequence is accelerated masonry damage from acidic condensate, turning a $1,200 repair into a $6,000 rebuild. We don’t scare-sell; we show you the camera footage and let the facts speak. Call (934) 348-4832 for a free estimate - estimates are free, and we’ll tell you if it can wait.
