Glance
Custom Fireplace supplies and installs premium non-combustible fireplace mantels in St. George and Southern Utah. Rather than fabricating mantels in-house, we curate an exclusive selection from two trusted makers — Lexington Hearth and Stone Mountain Castings — then professionally install them. Because these mantels are non-combustible, they allow reduced clearance above the fireplace, making it easier to mount a TV and create a cleaner, modern look.
Why It Matters

- Reduced clearance for TV mounting
- Look of real wood or stone
- Modern, rustic & traditional styles
- Won't warp, shrink, or odor like wood
- Professionally installed to fit

Cast Stone Mantels & Surrounds
Stone Mountain Castings
A premier Utah-based maker of cast and precast stone fireplace mantels and surrounds, known for attention to detail and timeless design. Their pieces deliver the look and feel of natural stone — with fire-safe materials that allow zero clearance to the firebox.
- Traditional stone & modern cast-concrete designs
- Fire-resistant, zero-clearance surrounds

Questions
Fireplace Mantel FAQs
How much does a fireplace mantel cost in St. George?
Mantel cost varies by brand, size, material, and installation. We'll walk you through the Lexington Hearth and Stone Mountain options that fit your space and provide a free, no-obligation quote.
Do you install fireplace mantels, or just sell them?
Both. We don't fabricate mantels in-house — we supply premium non-combustible mantels from Lexington Hearth and Stone Mountain Castings and professionally install them for a perfect fit and finish.
Are non-combustible mantels required?
Not always, but they're often the safer choice. Non-combustible mantels allow reduced clearance to the firebox, which makes installation safer and gives you more flexibility — especially when mounting a TV above the fireplace.
Can I mount a TV above a fireplace mantel?
Yes. Because our non-combustible mantels can sit closer to the heat source, they make it easier to safely mount a TV lower and create a cleaner, modern look.
Can you add a mantel to an existing fireplace?
Yes. We install mantels on both new and existing fireplaces, including remodel projects, and can tie them into a surround or built-in wall.
Do you serve Cedar City and surrounding areas?
Yes. We serve St. George, Washington, Hurricane, Ivins, Santa Clara, Cedar City, and the surrounding Southern Utah communities.
