Window installation service serving Greenville, SC since 2026

Brilliant Windows was founded in Greenville, South Carolina, with one clear purpose: give homeowners a window replacement experience they can actually feel good about. Too many companies in this space make big promises, drag out the install, and disappear when something goes wrong. We set out to do the opposite.

Our founder started Brilliant Windows after watching homeowners get burned, time and again, by contractors who overpromised and underdelivered. Slow timelines, inflated prices, and no clear point of contact when problems came up. That pattern was the reason to build something different from the ground up.

What makes us different is how we work. Every step, from your first appointment to the final installation, is handled in-house by our own team. There's no subcontracting, no handoffs to unfamiliar crews, and no guessing who to call if a question comes up. You always know who's accountable, because it's us, start to finish.

We specialize in window replacement, sliding glass door replacement, and door replacement. Whether you're replacing a single drafty window or upgrading multiple entry points across your home, we bring the same hands-on approach to every project. Our focus is on quality, energy-efficient products that make a real difference in your home's comfort and appearance.

We serve homeowners across the Upstate South Carolina region, including Greenville, Five Forks, Spartanburg, Greer, Travelers Rest, Clemson, Anderson, and Easley. As we grow, we're bringing that same customer-first approach to more communities across the area.

If you're ready to work with a local team that manages every detail and stands behind its work, we'd love to hear from you. Call us today at (864) 381-8702 or reach out at tyler@brilliantwindowsolutions.com to request your free estimate.
