How Gelco Products Fail - and How We Fix Them

Gelco builds solid chase covers, caps, and liners, but every brand has its weak spots. Here’s what we actually see in Long Island homes.

• Gelco stainless chase covers with failed silicone seams. The cover itself rarely rots, which is the point, but the factory silicone bead around the flue collar dries and separates after eight to ten years of Long Island freeze-thaw cycles. Water seeps in around the pipe, drips onto the firebox damper, and leaves rust streaks down the back wall of the firebox. We pull the old cover, clean the chase rim, and resecure it with a proper high-temp sealant that moves with the metal.
• Gelco multi-flue caps trapping creosote at the mesh screen. Gelco’s mesh is fine enough to keep birds out, which matters on Long Island, but on a wood-burning flue that mesh loads up with first-degree creosote fast. By mid-season, draft drops because the screen is half clogged. During a sweep, we pull the cap and brush the screen clean every visit, and we’ll tell you if the mesh has gotten so gummed up it’s smarter to replace the cap than fight it year after year.
• Gelco flex liners that were never insulated on exterior chase walls. A Gelco flex liner on an exterior chase chimney on Long Island sweats when the cold Atlantic air hits the metal from outside. Condensation mixes with creosote, and you get that thick, sour buildup that takes two or three passes with a rotary whip to remove. We’ve insulated dozens of these liners after the fact, and the difference in draw is immediate.
• Take-off plates and storm collars from older Gelco installations loosening over time. The sheet metal screws Gelco uses on the take-off plate back out after years of heating and cooling. The plate rattles in a nor’easter, and water gets in around the collar. Simple fix, fifteen minutes, but only if a sweep notices it while up on the chase. We check every Gelco take-off plate on every sweep.
• Galvanized Gelco caps on wood-burning flues. Galvanized steel and creosote are a bad marriage. The acid in creosote eats the zinc coating, and once the galvanizing is gone, the cap pinholes within two seasons. If you’re burning wood with any regularity on Long Island, step up to the Gelco stainless cap. It costs a little more and stays on the chase for a decade.

Our Gelco Chimney Cleaning & Sweep Process

Here’s what happens when you call us for a Gelco sweep in Long Island.

1. 1
   Call and talk to a live person. Frequently that’s Wendell himself. You’ll get a straight price range on the phone, and we’ll book a real arrival window, not a “sometime Tuesday.”
2. 2
   Arrive, lay drop cloths, set up the vac. We protect the hearth and the path to the door. Always.
3. 3
   Run a camera up the flue before the brush touches anything. On a Gelco liner, we want to see the condition of the liner, the cap screen, the rain collar, and any water staining. You see the footage too, and you get a plain-English verdict on what needs attention now, what can wait, and what’s fine.
4. 4
   Sweep the flue and clean the smoke chamber, damper, firebox, and cap. The mesh screen on a Gelco cap gets brushed clean whether it looks dirty or not. It always is.
5. 5
   Check the chase top and flashing while we’re up there. Gelco covers are good, but the silicone and the fasteners are the weak link. We reseal or snug up anything looking tired.
6. 6
   Walk you through what we found, then leave it cleaner than we found it. You get the 90-Day Done Right Promise in writing. If something isn’t right, one call brings Wendell back at no charge.

What Gelco Chimney Cleaning & Sweep Costs in Long Island

A standard open-flue Gelco chimney sweep on Long Island runs $189 to $249. Add a Gelco multi-flue cap cleaning and inspection, and you’re at $249 to $289. A full Level 2 inspection with camera documentation on a Gelco setup runs $349 to $399, and that includes the sweep. Here’s what moves the price:

• Single vs. multi-flue. Two flues means two runs and twice the time, so plan on $329 to $389 for a two-flue Gelco setup.
• Third-degree creosote glaze. If the liner has a hard, shiny glaze on it, standard brushing won’t cut it. Rotary cleaning with a chain whip usually adds $75 to $125.
• Cap condition. If the Gelco cap screen is shot or the galvanized cap has pinholes, replacement runs $150 to $400 depending on material and flue count.
• Access. A steep roof pitch or a chase top that needs a taller ladder adds a modest access fee. You’ll hear that number before we book, not after the job.

Every estimate is free, and if someone else handed you a written estimate for the same Gelco work, bring it. We’ll give you a second opinion at no charge. Call (516) 968-5380.

Why Long Island Homeowners Call Top Hat Chimney for Gelco Work

We’ve been going up these exact chases since 1999. Wendell Pike signs his name to the work, publishes his license number, and stands behind every Gelco sweep and repair with a 90-Day Done Right Promise in writing. If the job isn’t right, one call and we’re back. No charge. That’s not a slogan, it’s printed on the invoice. Our phones are answered by a real person day and night, every technician is background-checked and shows up in a uniform with a real arrival window, and the number you heard on the phone is the number on the invoice. We also work with DuraFlex and HeatShield systems, so when a Gelco liner has failed beyond saving, we can line the flue with a brand-name liner that fits properly and drafts well. Ask anyone on your street. Chances are decent we’ve been up their chimney too.
