Gelco Chimney Repair Nationwide

Gelco Chimney Repair in Hicksville: What to Know First

We provide independent Gelco chimney repair in Hicksville, with most jobs completed in a single visit and upfront pricing agreed before we start. Typical turnaround from call to repair is three to five business days during the off-season, longer when every homeowner on Long Island books at once before the first cold snap. We’re not the cheapest option in Nassau County, and we don’t try to be - we charge enough to do the job with professional-grade materials and stand behind it for 90 days, in writing.

Call (516) 259-3797

This page is for Gelco owners in Hicksville who’ve noticed crumbling mortar, water stains on the ceiling near the flue, or a cap that doesn’t sit square anymore. Maybe a previous sweep told you the repair would cost more than your car. Maybe you’re just tired of wondering whether your chimney is the thing that’s going to let cold water into your walls this February. Call us at (516) 259-3797. A live person answers, 24 hours a day.

How Gelco Products Fail - and How We Fix Them

• Gelco stainless caps with mesh sides - screen corrosion at the welds. The Series 8 and Series 9 multi-flue caps we see around Hicksville’s 1960s ranches and split-levels hold up well on top, but the 304-grade mesh welds start weeping rust after fifteen to twenty years in Nassau County’s salt-air environment, sooner if you’re within a few miles of the LIRR corridor. We don’t slap on a generic replacement. We measure the flue count and dimensions, then source either a Gelco OEM cap or a matching-gauge Copperfield equivalent with 316-grade mesh that buys you another generation.
• Gelco top-sealing dampers - cable seizure and gasket hardening. The Lyemance and Lock-Top lines are clever designs, but the stainless cable runs through a narrow housing that collects creosote dust and seizes if the homeowner never opens the damper in summer. The silicone gasket also bakes to leather-hardness after a decade of Hicksville’s freeze-thaw cycles. We disassemble the housing, clean the cable run with a proper solvent (not WD-40, which gums up), and replace the gasket with a factory-matched part. If the frame is warped from a chimney fire the owner didn’t know they had, we document it with photos and explain why a new damper makes more sense than a third repair.
• Gelco chimney pots - base cracking from thermal shock. The English-style and Edgeworth pots we install on colonial revivals near Broadway Mall look substantial, but the terracotta body expands at a different rate than the concrete base in rapid temperature swings. Hicksville’s late-autumn cold fronts - 60 degrees at noon, 28 by midnight - are hard on them. We remove the pot, rebuild the shoulder with HeatShield refractory mortar rated to the pot’s expansion coefficient, and reset it with a proper bedding of high-temp sealant. No silicone caulk. That fails in six months, and we won’t use it.
• Gelco chase covers - corner pooling and rust-through. The pre-fab galvanized covers on factory-built chimneys in the Levitt-era sections of Hicksville were never meant to last forty years, but they do, and then they leak at the corners where the drip edge was formed too tight for water to run off. We fabricate a replacement from 24-gauge stainless or copper if the homeowner wants the look, with cross-breaks welded in to prevent pooling. We also extend the drip edge past the chase wall by an inch and a half - Gelco’s original spec was tight, and water follows surface tension right back to the wood.
• Gelco liner connections - joint separation at the tee. The Gelco ProFlex and similar corrugated liners we encounter in older Hicksville brick chimneys sometimes pull apart at the tee connection where the appliance adapter meets the liner body. This happens when the original installer didn’t use the correct Gelco compression band or substituted a generic hose clamp. Exhaust leaks there, and you get condensation in the chase or worse. We snake a camera down to confirm the gap, then rebuild the connection with the proper Gelco band or a DuraFlex equivalent of matching gauge, torqued to spec and photographed for the report.

Our Gelco Chimney Repair Process

1. 1
   Call and schedule. A live person answers, asks what you’re seeing, and books a two-hour arrival window. No app. No callback queue.
2. 2
   Level-2 camera inspection. Our technician runs a camera from the firebox to the cap, photographing every joint, every crack, every place water has been. You see the photos on a tablet before we write the estimate. The chimney doesn’t care what you hoped it was - it shows you what it is.
3. 3
   Parts decision: OEM or quality aftermarket. If Gelco still produces the exact part, we quote it. If it’s obsolete or the lead time is unreasonable, we explain the DuraFlex, HeatShield, or Copperfield equivalent and why it matches or exceeds the original spec. You decide. We don’t decide for you.
4. 4
   Repair with upfront pricing. The number on the estimate is the number on the invoice. Most Gelco repairs - cap replacement, damper rebuild, chase cover fabrication - finish in one visit because our trucks carry the common sizes and materials.
5. 5
   Post-repair test and documentation. We run the camera again to confirm the fix, draft-test where applicable, and email you the photos with a plain-English summary. The 90-Day Done Right Promise goes in writing before we leave.
6. 6
   Cleanup and follow-up. We tarp the work area, vacuum what we disturbed, and call in three weeks to make sure you’re satisfied. If something’s not right, we come back. No paperwork to file. No arguing.

Why Hicksville Homeowners Call Hearthstone Chimney Co. for Gelco Work

We’ve been working on chimneys in Hicksville since the early 1980s, back when the Gelco name was more common on new construction here than it is now. Russell Haines and our technicians know which Gelco parts interchange with current DuraFlex and HeatShield lines, and which don’t - knowledge that saves you from ordering a discontinued component that sits in a warehouse for six weeks while your ceiling stain grows.

Our 90-Day Done Right Promise means if the repair fails, we make it right. In writing. No arguing. Our trucks carry the materials to complete most Gelco jobs in a single visit, and our background-checked, uniformed technicians explain what they found before they explain what it costs. We’ve also got the multi-brand depth to solve problems no single manufacturer can: when a Gelco liner needs a HeatShield sleeve or a DuraFlex adapter, we know the combination because we’ve installed it, documented it, and stood behind it.

And when you call (516) 259-3797, a live person answers. Every hour of every day. That’s not a gimmick. It’s how we’ve done business for over 42 years.
