  • We broke our double pane window & called everywhere looking for someone who could help us, until we found Golden Triangle. They were ready to close in 30 minutes when we called but told us if we could bring the window down, they’d be able to at least put some plexiglass in until they could get us an all new sash shipped in. They stayed for a whole hour after closing & ended up putting real glass in on one side until the other piece of glass is available so we weren’t exposed to the elements tonight. We couldn’t be more thankful for the outstanding customer service and amazing prices that Golden Triangle Glass provides to their customers!

  • Very quick service. They came out for an estimate an hour after I called them and called to schedule installation as soon as the glass arrived to them (which was faster than expected). The install was quick and clean; they even removed and vacuumed the remaining broken glass that was left in the window. The price was fair. Would definitely use them again.

  • Denny and Fred were awesome to work with. We had a 4 panel bow window that had the center 2 panels fogged from gas leaking out. Called several places and these guys did a fantastic job for 1/2 the cost of others! Highly recommend their services!!

  • Dennis was extremely professional, reasonable, and prompt. I was blown away by the quality of the shower door he and his guys installed that beat the local competitors by hundreds. Golden Triangle is a quintessential local business and I highly recommend.
