We handle Gelco chimney repair in Newark as an independent service provider, and most jobs are done within one to three days of the initial inspection. Repair pricing on Gelco units typically lands between $250 and $1,800 depending on whether we’re repointing mortar, rebuilding a crown, or addressing liner damage behind the Gelco components. You’ll get an exact number before any work begins, and if the chimney doesn’t need the repair you thought it did, we’ll tell you that straight and save your money.

Call (848) 331-2638

This page is for Newark homeowners who own a Gelco chimney system or have Gelco components on their chimney and need honest repair work from a local shop that answers its own phone. If you’re looking at water stains on the ceiling near the flue or crumbling mortar around the chase, call (848) 331-2638 and we’ll walk through what you’re seeing.

How Gelco Products Fail - and How We Fix Them

• Gelco chimney caps and chase covers corroding at the seams. We see this most on Newark rowhouses where the chase cover takes direct weather off the Passaic River corridor. Gelco’s multi-rivet aluminum chase covers hold up fine in dry climates, but Newark’s freeze-thaw cycles plus the salt air coming up from the port makes those rivet points oxidize first. Once the seam opens, water gets into the chase and runs down around the flue. We replace with a heavier-gauge stainless cover, custom-bent on site, and seal the corners properly.
• Mortar joints failing around Gelco flue tiles. The flue tiles themselves are usually solid. What gives out first is the mortar between them. In Newark homes built before 1960, we regularly find the original clay mortar has turned to sand behind the Gelco components. You’ll see it as fine grit collecting in the cleanout door or in the firebox after heavy rain. We remove the loose material, repoint with a high-temperature refractory mortar, and if the joints are too far gone, we’ll talk to you about a HeatShield resurfacing instead of a full teardown.
• Gelco termination caps pulling loose from the crown. This one shows up a lot on Irvington and Vailsburg chimneys where the crown has cracked and the cap’s mounting legs no longer anchor into solid concrete. The cap will sit there looking fine until a nor’easter comes through, and then you’ll hear it rattling. We reset the cap into a rebuilt crown and re-anchor the legs with stainless hardware. If the cap itself is bent or warped, we can source a replacement that matches the existing footprint.
• Condensation staining inside the chase on Gelco air-cooled systems. Gelco air-cooled chimney systems rely on air moving through the chase to keep the flue from overheating the surrounding framing. When a Newark homeowner adds insulation or seals up the chase chasing energy savings, that airflow stops and condensation builds up inside. What you’ll see first is dark staining on the outside of the chase or peeling paint near the ceiling line. The fix is usually not a new chimney, it’s restoring proper chase ventilation. That’s a two-hundred-dollar correction versus a five-thousand-dollar replacement, and it’s the kind of thing we will always check before quoting anything larger.
• Spalling brick behind or below Gelco chase installations. Where the Gelco chase meets original masonry, the brick goes first. Newark brick from the 1920s and 30s is soft, and once water gets behind the chase flange and sits against that brick through a few winters, the brick face starts popping off in chunks. You’ll find pieces on the ground next spring. We remove the damaged brick, match it as closely as current brickyards allow, and rebuild the section with proper weep holes so the water has somewhere to go next time.

Our Gelco Chimney Repair Process

1. 1
   You call, we answer. A live person picks up, day or night. You describe what’s happening with your Gelco chimney, and we’ll tell you whether it sounds urgent or whether it can wait a few weeks.
2. 2
   We come out and inspect, no trip charge inside the county. Wendell or one of his crew will get on the roof, check the cap, crown, flashing, and the flue behind the Gelco components. You get the camera footage and a plain-English verdict, every time, no exceptions.
3. 3
   We decide parts together. If it’s a Gelco-specific component like a cap or chase cover, we’ll tell you honestly whether OEM makes sense or whether a quality aftermarket stainless part will outlast it for less money. If the flue liner is compromised, we’ll show you the camera before recommending HeatShield or a DuraFlex liner. Nothing gets recommended without evidence.
4. 4
   We do the repair. Whether it’s repointing mortar, rebuilding a crown, sealing flashing, or resetting a Gelco cap, the work gets done with materials built for Newark weather. Background-checked, uniformed, and on time.
5. 5
   We test and you get the verdict. After the repair, we run the system or water-test the exterior. You see the before and after photos. If anything’s not right, it falls under the 90-Day Done Right Promise and we’re back out, no charge.
6. 6
   We leave the site cleaner than we found it. Debris hauled off, walkway swept, and the chimney looking like it should.
