We provide Gelco in Cherry Hill with independent chimney cleaning, repair, and relining service throughout the area - not as an authorized dealer, but as a crew that has worked on Gelco stainless liners since the brand was still sold under the Copperfield name. Our technicians carry Gelco-compatible top plates, appliance adapters, and insulation kits on every truck, and we back every job with our 90-Day Done Right Promise in writing.

Cherry Hill’s housing stock was built almost entirely during a single concentrated suburban boom in the 1960s and 1970s, triggered by the 1961 opening of Cherry Hill Mall and rapid Philadelphia-area flight to Camden County suburbs. That means the township has an unusually dense concentration of similarly-aged masonry chimneys, most now 50-60 years old and hitting the same critical deterioration window simultaneously. A large share of those homes later converted from oil-fired furnaces to natural gas without relining the chimney through our Chimney Cleaning & Sweep services, leaving original terra cotta flue tiles sized for high-temperature oil exhaust now venting cooler gas appliances. That mismatch promotes condensation, acidic byproduct buildup, and accelerated liner failure - exactly the conditions Gelco stainless and aluminum liners were designed to solve, and exactly the conditions we diagnose and repair weekly in Cherry Hill neighborhoods from Barclay Farm to Erlton.

Why Trust Hearthstone Chimney Co. for Your Gelco Chimney Cleaning?

Russell Haines, our owner, grew up in Los Angeles and picked up his trade fundamentals at Los Angeles Trade-Technical College before spending the better part of two decades working chimneys up and down the East Coast. He and our crew have served Cherry Hill for years, including older colonials over in the Barclay Farm neighborhood where the fireplaces run nearly as old as the subdivision itself. Russell is known for thorough inspections and straight talk - if the flue is fine, he tells you it is fine, and if it is not, he tells you exactly why and what it will take to fix it.

That same directness runs through how we handle Gelco systems. We are not affiliated with or authorized by Gelco. We are an independent chimney company. But our day-in, day-out familiarity with Gelco’s multi-fuel liner line means we can diagnose and fix problems other companies misread. We know the difference between a Gelco TherMix insulated liner and a Gelco Z-Flex flexible liner, and we know which failure modes each one develops in Cherry Hill’s freeze-thaw climate. We stock genuine Gelco top plates and appliance adapters for warranty-safe repairs, and we carry equivalent UL-1777 components from DuraFlex and HeatShield for out-of-warranty systems where OEM parts no longer make sense.

Every inspection ends with photos you can see and a plain-English verdict. No surprises on the bill - the number on the estimate is the number on the invoice. And our 90-Day Done Right Promise means if it’s not right, we come back. In writing. No arguing.

Common Gelco Chimney Cleaning Problems We Fix in Cherry Hill

• Top-plate seal failure on Gelco Copperfield and Z-Flex liners. The silicone or mortar bond at the crown cracks, letting water run down the outside of the Gelco liner. In Cherry Hill, we see this constantly after nor’easters drive wind-driven rain into chimneys whose crowns have never been replaced since original construction. The water rusts the appliance connector and stains the chimney chase. We pull the old top plate, inspect the liner crown for damage, and install a new Gelco-compatible top plate with a fresh gasket seal.
• Creosote glaze on wood-burning Gelco TherMix liners. The stainless holds up fine, but the glazed flue is a chimney-fire hazard. This happens when homeowners burn unseasoned wood - we see it especially in Cherry Hill where “seasoned” firewood from big-box stores often still carries 30% moisture. The TherMix insulation keeps the flue hot enough to reduce buildup, but it does not eliminate it. We rotary-clean the flue with mechanical brushes, not liquid “sweeps” that leave residue behind. The chimney either draws the way it should, or it does not - and we will not leave until we know which.
• Aluminum Gelco gas liners corroding at the appliance adapter. Cherry Hill has hundreds of homes that converted from oil to gas heat in the 1980s or 1990s. Some got aluminum Gelco gas liners sized for mid-efficiency furnaces. Then the homeowner upgrades to a 96% high-efficiency unit, and the flue temperatures drop even lower. The existing aluminum liner was never meant for that condensate load. We find corrosion, separation at the adapter, or white acidic residue. Sometimes we can reline with a properly sized stainless gas vent; sometimes the whole chase needs evaluation.
• Insulation wrap tearing or shifting inside the flue. This happens when a previous installer pulled the Gelco liner through rough terra-cotta tile without proper guidance. The tear creates hot spots where the liner runs too close to combustibles, and it can fail NFPA 211 clearance requirements. We camera-inspect to locate the damage, then either repair the insulation with a Gelco-compatible wrap or recommend a full reline if the liner itself is scored or punctured.
• Dual-flue cross-contamination in Cherry Hill’s split-level and ranch chimneys. Many 1960s-1970s tract homes here have a single chimney chase serving both a living-room fireplace and a basement mechanical-room flue. If one flue was relined with Gelco and the other was not, or if the Gelco liner was improperly capped, exhaust can migrate between flues. Our Level-2 camera inspection checks both flues for draw, blockage, and separation. We document everything with photos and tell you exactly what we found.

Gelco Parts & Our Repair-vs-Replace Approach

For Gelco liners still under factory warranty, we use genuine Gelco top plates, appliance adapters, and insulation kits. That keeps the warranty intact. For out-of-warranty systems or discontinued Gelco parts, we install equivalent UL-1777 stainless components from DuraFlex or HeatShield. Both are professional-grade brands we trust, and both carry the same safety ratings.

We recommend a full reline only when the existing Gelco liner has punctures, separated seams, or failed insulation. Otherwise we repair and re-seal. A top-plate reseal costs a fraction of a reline, and in Gelco service in Camden and Cherry Hill’s climate, it often adds another decade of service to an otherwise sound Gelco system. We will show you the camera footage and explain which category you’re in. No pressure. Call (856) 543-2929 for an exact quote - estimates are free.

Our Gelco Service Process - Step by Step

1. 1
   Diagnosis with Level-2 camera inspection. We run a high-resolution camera through your Gelco liner from top to bottom, looking for glaze, separation, insulation tears, and top-plate seal condition. You see the photos. We explain what they mean in plain English.
2. 2
   Repair or install with Gelco-compatible parts. We stock genuine Gelco components and equivalent DuraFlex or HeatShield parts for warranty or out-of-warranty work. For cap replacement, we install stainless multi-flue caps sized to your Gelco liner. For waterproofing, we apply vapor-permeable crown sealant that lets moisture escape without letting new water in.
3. 3
   Testing and verification. We fire the appliance and verify draft, check for spillage at the appliance connection, and confirm the liner is drawing correctly. On gas systems, we test for proper venting with a combustion analyzer.
4. 4
   Warranty documentation. We provide written documentation of the work performed, parts used, and photos of the completed installation. That paperwork supports any future Gelco warranty claim and backs our own 90-Day Done Right Promise.
