Gelco Crown Repair Nationwide

Gelco Crown Repair: The Fort Worth Owner’s Guide

We stock and install Gelco-compatible crown repair parts across Fort Worth, with most jobs running between $385 and $720 installed depending on crown size and how much of the existing mortar bed needs rebuilding. We can usually have a technician out within a few days, and in many cases it’s a same-week fix once we confirm the measurements. Most owners discover the problem the way you probably did: water staining on the ceiling near the fireplace, a damp smell in the room after a hard rain, or visible cracking in the concrete crown when you looked up at the top of the chimney.

If you’ve got a Gelco fireplace system and the crown is showing its age, this page will walk you through exactly what’s going on, what it costs in the Fort Worth market, and what the repair actually involves before anyone touches your home.

Which Gelco Models This Applies To

Gelco crowns sit on top of the chimney chase on a wide range of factory-built fireplace systems, and the repair we do is tailored to the specific chase dimensions and crown overhang your unit was built with. The crown isn’t typically tied to a single Gelco model number the way a gas valve or burner assembly would be. Instead, it’s matched by measuring the outside chase dimensions, the flue pipe diameter, and the drip edge overhang, then forming the crown to fit those numbers exactly.

What you’ll want to have on hand when you call is the Gelco nameplate or rating plate, usually found behind the lower access panel or inside the firebox door frame. That tells us the model and serial number, which helps us confirm the venting configuration before we order the right crown form or fabricate one on site. For the crown itself, we use a properly sloped concrete mix with a drip edge that sheds water away from the chase, rather than letting it run down the siding. In our experience, Gelco chases on older Fort Worth homes often have a thinner original crown than what current best practice calls for, which is why we see so many of them cracking after fifteen or twenty years of Texas sun and rain.

One note for clarity: Kindling Chimney Fort Worth is an independent service provider. We’re not affiliated with Gelco, but we work with their parts and specifications regularly, and we stock the materials to rebuild or repair crowns on Gelco systems without waiting on a factory order.

Key takeaways:

• Your Gelco model number helps us confirm venting, but the crown is matched to your chase measurements.
• We carry the forming materials and crown-grade mix on the truck.
• The repair is sized to your chimney, not a one-size-fits-all cap.

Signs Your Gelco Crown Repair Is Failing

• Visible cracks in the crown surface. Hairline cracks let water in slowly. Once they widen to a credit card’s thickness, the freeze-thaw cycle has already started breaking the concrete apart from the inside.
• Water staining on the ceiling near the fireplace. This usually means water is getting past the crown and running down the chase interior, then soaking into the ceiling drywall below the roofline.
• Damp or musty smell in the fireplace room after rain. Moisture trapped inside the chase gets pulled into the home’s air. In Fort Worth’s humid summers, that smell can hang around for days.
• Spalling or crumbling concrete at the crown edges. This is the crown surface flaking away in thin layers. It happens when water soaks in and the minerals in the concrete break down, especially after years of North Texas sun baking the surface.
• Rust stains running down the chase or siding. Water has already saturated the crown and is now carrying mineral and metal staining down the outside of the chimney structure.

Replacement Cost & What’s Included

In Fort Worth, a full Gelco crown rebuild on a standard residential chase typically lands between $385 and $720 installed. Smaller chases with minimal damage sit at the lower end. Larger chases, thicker original crowns that need full demolition, or repairs that also require replacing the chase top flashing will push toward the upper end. You’ll get a written price before any work starts, and that price is the price: no surprise add-ons at the end of the job.

What’s included in that number: removal of the failing crown material, forming and pouring a new properly sloped crown with an adequate drip edge, cleanup of the work area, and our 365-Day Done Right Promise on the repair. If the crown doesn’t hold up within that first year, we make it right at no charge. We also take a photo of the cleanup before the crew leaves, so you can see exactly how we left the area around your chimney, the roof access point, and the ground below.

The cost is parts plus labor, and we use a crown-grade concrete mix designed for chimney exposure, not a basic bag mix from the hardware store. That matters in Fort Worth, where a crown has to hold up to 100-plus degree summer days and the occasional hard freeze within the same year.

DIY or Call Us?

You can safely check a few things from the ground: look for visible cracks, crumbling edges, or staining on the chimney chase. Binoculars help. What you shouldn’t do is get on the roof and try to patch it yourself. Crown repair requires getting the old material off cleanly, forming a proper slope, and working safely at roof height around the flue pipe. A bad patch job traps water underneath it, and then you’ve got the same problem plus a layer of patch material hiding it.

There’s also the safety side. Working on a roof around a chimney is a fall risk, full stop. Our technicians carry the right roof safety gear and we’d rather have you watch from the kitchen window than test your ladder skills. If you’ve spotted a failing crown, call us at (682) 382-9934 and we’ll come take a proper look before you spend anything.
