Got a neo-angle shower installed with beautiful brass hardware — fits perfectly in the smaller bathroom and looks incredible. The quality is outstanding and the whole team was professional from start to finish. Very happy with the result.

American Glass Experts is one of the best in the game. Bryant and Frank are true professionals — they go above and beyond to make sure you're satisfied. Highly recommend them for any glass need, big or small.

I wasn't sure about going frameless at first but Frank and Bryant took the time to walk me through the design options and explain what would work best. The result is exactly what I hoped for — solid, quality work from a team that clearly knows their craft.

Got a mirror installed in the master bathroom and it turned out really nice. They offered 1/4-inch mirror and the quality is solid. Fits perfectly on the wall. Clean work, straightforward process.

From the first call to the final installation, everything was perfect. Bryant and Franklin helped turn our shower glass vision into exactly what we wanted. Professional, skilled, and a real pleasure to work with.

Needed a broken window replaced and American Glass Experts exceeded all expectations. Exceptional attention to detail — installed seamlessly and fast. The team made sure everything was clean and tidy after the job. Would definitely hire them again.
