Gelco Chimney Liner & Rebuild Nationwide

Every visit starts with

Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed

Worth knowing

Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

This page is for Easton homeowners with Gelco liners installed from the 1990s through the mid-2010s, especially those in older colonials near the Delaware Canal where freeze-thaw cycling is hardest on chimney infrastructure. Russell Haines and our crew have worked on hundreds of these systems. We’re not affiliated with or authorized by Gelco. We’re an independent service provider who knows what fails and what lasts.

How Gelco Products Fail - and How We Fix Them

  • Gelco Pro-Flex 316Ti flexible liners: The corrugated wall can work-harden at stress points where the liner bends around a smoke shelf or thimble offset. In Easton, we’ve found this accelerated by acidic condensation from burning unseasoned hardwood, common in homes that heat primarily with fireplace inserts. We cut back to sound metal and splice in a new Pro-Flex section with an improved support system, or transition to DuraFlex if the damage is extensive.
  • Gelco stainless rigid liner systems (Model 3000 series):strong> The telescoping joint above the fireplace can loosen after 15-20 thermal cycles per season. Easton’s temperature swings, especially the January freeze-thaws, cause the male-female joint to back out slightly. We reseat with high-temp sealant and mechanical locking bands; if the joint is ovalized, we replace with OEM or compatible rigid sections.
  • Gelco terra cotta-to-steel transitions: Older Easton installations sometimes used Gelco steel liners dropped into partially intact clay flues. The gap between dissimilar materials traps moisture. We’ve pulled liners in College Hill homes where the terra cotta spalled so badly it blocked the flue. We remove the compromised clay and install a properly sized, insulated Gelco or HeatShield liner system.
  • Gelco top plates and storm collars: The original galvanized hardware on pre-2010 Gelco installations rusts through at the exposed edge. Water tracks down the exterior of the liner and pools behind the fireplace. We replace with Gelco-compatible 304 stainless top fittings or upgrade to Copperfield components where the homeowner wants maximum longevity.
  • Gelco liner insulation blankets: The foil-wrapped ceramic blanket can settle or compress in tall Easton chimneys, especially the three-story Victorians in the West Ward. Hot spots develop where the liner lacks clearance to combustibles. We verify with a video scan, then re-insulate with fresh blanket and mesh or switch to a listed air-cooled system if the chase is too tight for proper blanket thickness.

Our Gelco Chimney Liner & Rebuild Process

  1. 1
    Call and schedule. A live person answers, 24 hours a day. We book a two-hour arrival window. No deposit required.
  2. 2
    Level-2 camera inspection. Our technician runs a chimney camera from top to bottom, or bottom to top if the flue is blocked. You see the footage on a tablet. We mark timestamped photos of cracks, gaps, or liner separation.
  3. 3
    Plain-English verdict and parts decision. We explain whether your Gelco component can be repaired or needs replacement. If Gelco OEM is backordered, we source compatible aftermarket from our Olympia Chimney or Famco inventory, or shift to DuraFlex or HeatShield if that’s the better long-term value. You approve the scope and price before we start.
  4. 4
    The rebuild or liner install. Background-checked, uniformed technicians complete most Gelco liner replacements and partial rebuilds in one visit. We use proper drop cloths, HEPA vacuums, and respect the house.
  5. 5
    Smoke and draft test. We verify negative pressure, check spillage at the appliance, and confirm the liner is pulling correctly. You get a written report with photos.
  6. 6
    Cleanup, payment, and guarantee. We leave the work area cleaner than we found it. The 90-Day Done Right Promise goes in writing before we leave. If it’s not right, we make it right. No paperwork, no arguing.

What Gelco Chimney Liner & Rebuild Costs in Easton

These are real ranges for Gelco-specific work we’ve completed in Easton and the Lehigh Valley. Your exact estimate depends on chimney height, access, and what the camera reveals.
