A Hearthstone company - serving Ewing, NJ

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.

Gelco Chimney Liner & Rebuild in Ewing: What to Know First

We provide independent Gelco chimney liner and rebuild service in Ewing, with most Gelco liner replacements and partial rebuilds completed in a single visit after our Level-2 camera inspection. As an independent Gelco service provider, we carry OEM-compatible Gelco parts alongside professional-grade alternatives from DuraFlex and HeatShield, and we quote every job upfront before any work begins. Gelco stainless steel liners and flexible liner kits have been common in Ewing homes since the 1990s, especially in the split-levels and center-hall colonials near the Ewing-Lawrence border where we have worked for years. If your Gelco liner is showing gaps, your masonry is spalling, or you are getting smoke backup on cold starts, call (856) 388-5580. A live person answers, and the estimate is free.

How Gelco Products Fail - and How We Fix Them

  • Gelco 316Ti stainless rigid liners develop creosote pinholing at the weld seams near the smoke chamber, especially in Ewing’s freeze-thaw climate where condensation sits in the flue through March. We cut back to sound metal and splice in a Gelco-compatible 316Ti section, or transition to DuraFlex if the entire run has thinned.
  • Gelco flexible liner kits (the accordion-style) collapse at the offsets in pre-1980 Ewing chimneys that were never built for inserts. The flex gets compressed against the rear wall where the flue tilts toward the foundation. We pull a new Gelco flex with a proper ovalization at the offset, or switch to a rigid DuraFlex hybrid where space allows.
  • Gelco UL-listed top plates and collars corrode at the storm collar joint when Ewing’s nor’easter-driven rain gets past a loose-fitting cap. Water tracks down the liner and pools at the thimble. We replace with a Gelco OEM top plate or a Copperfield equivalent with a machined storm collar, and we always reseal with high-temp silicone rated to 500°F.
  • Gelco HeatFab and early welded seam liners separate at the tee body in wood-burning setups where homeowners have burned unseasoned oak from the Sourland Mountain area. The acidic creosote eats the weld from the inside out. We pull the tee, inspect the wye for wall thinning, and either weld-repair with a Gelco-certified sleeve or replace the entire tee assembly.
  • Gelco poured-in-place liner systems crack at the flue shoulder where the liner meets the smoke shelf, particularly in Ewing’s clay-heavy soil zone where foundation settling is common in homes south of Scotch Road. We do not pour over cracks. We remove the failed refractory, install a stainless liner or apply HeatShield cerfractory foam if the clearance to combustibles permits, and document the before-and-after with photos you can see.

Our Gelco Chimney Liner & Rebuild Process

  1. 1
    Call and schedule. A live person answers at (856) 388-5580, 24 hours a day. We book a Level-2 camera inspection, not a sales visit.
  2. 2
    Inspect and document. Our technician runs a camera the full length of your Gelco liner, photographs every joint, offset, and thimble, and records video of any breach or thinning. You see the photos. We explain what we found in plain English.
  3. 3
    Diagnose and quote. We identify whether your Gelco part is still manufactured, whether an OEM replacement is warranted, or whether a DuraFlex or HeatShield alternative gives better longevity for your burn habits. The price is fixed before we start.
  4. 4
    Repair or rebuild. For liner jobs, we pull the new liner, secure the top plate, and seal all joints with Gelco-approved fasteners or high-temp hardware. For rebuilds, we match existing brick coursing and install a new crown with proper drip edge and expansion joint.
  5. 5
    Test and verify. We pressure-test or smoke-test every liner installation, run the camera again to confirm clear passage, and check draft with a manometer on cold start.
  6. 6
    Clean up and guarantee. We haul away all debris, leave the work area as we found it, and hand you the 90-Day Done Right Promise in writing. If it is not right, we come back. No paperwork, no arguing.

What Gelco Chimney Liner & Rebuild Costs in Ewing

These are real ranges for Gelco-specific work we have quoted in Ewing over the past three seasons. Your exact price depends on flue length, access, and whether we can reuse your existing cap or top plate.

  • Gelco flexible liner replacement (single flue, standard height): $2,200-$3,400
  • Gelco 316Ti rigid liner replacement with new top plate: $2,800-$4,200
  • Gelco tee and wye assembly replacement (wood-burning): $1,400-$2,100
  • Partial chimney rebuild (above roofline, including Gelco liner reconnection): $4,500-$7,800
  • Full chimney rebuild with new Gelco-compatible liner system: $8,500-$14,000
  • HeatShield cerfractory foam repair (Gelco poured-in-place alternative): $1,800-$2,600

What moves the price: roof pitch and access, whether the existing Gelco liner is stuck and must be cut out in sections, and whether the chimney crown and wash are salvageable. We do not recommend work without camera evidence you can see for yourself, and we will tell you plainly when a repair can safely wait a season. Call (856) 388-5580 for an exact quote. Estimates are free.

Why Ewing Homeowners Call Hearthstone Chimney Co. for Gelco Work

We have cleaned and inspected chimneys throughout Ewing, including older homes near the Ewing-Lawrence border along Bear Tavern Road, long enough that a few of those customers are now on their second generation of calling us in before the cold sets in. Our technicians are background-checked, uniformed, and trained on Gelco’s specific connection hardware, not just generic liner pulls. When Gelco has discontinued a part, we have the DuraFlex or HeatShield cross-reference already in our van. Every job ends with photos, a plain-English verdict, and the 90-Day Done Right Promise in writing. If the flue is right, the fire takes care of itself. Russell Haines and our crew plan to be serving Ewing for decades yet, so we do not cut corners that would bring us back to fix our own mistake.
