What Our Customers Say
Real feedback from satisfied clients across Southern California.
“Fantastic quick service!!! Kris Gonzalez was 1/3 the cost of 3 other quotes to adjust a glass shower door; he did it in 30 minutes flat!! All other companies wanted $300–$395 for the same job he did for a $125 quote!!!! So I tipped him $75 and told him his price was excellent and his work highly professional. He was very grateful! So so happy that there are businesses out there still who are honest and fair. We will absolutely only hire Pristine Glass for any of our glass needs.”

“Fantastic! I installed one large sliding door in one shower and another normal door in a smaller one, as well as a shelf in my shower niche. Kris is fast, professional, and competitively priced. I would call him again anytime and have already recommended him to two other friends.”
