Black Diamond Window Works

Kitty approved views! Matt did an excellent job of cleaning my windows. I can't believe how much brighter, lighter, and cleaner my space feels. He was attentive, thorough, and communicative throughout the entire process and I look forward to hiring him again.

I wish I could say something good about this company. The windows look good but he broke one window and now I am unable to have it stay open. He was highly stressed because I live in a dense area of Denver, and he was unable to find a parking spot quickly. Left saying that he didn't know if the window wasn't working before he cleaned it, I assured him it was, and he was quite rude and left. I own my own business and would never treat a client like this. I would also make sure all was in working order before I left a client with a broken window.

Matt responded timely to my request for a quote. He was prompt, professional and did a great job on our windows.

Matt did an incredible job on our home’s (old and finicky) windows. He was super responsive and very flexible with scheduling, squeezing us in last minute when another company canceled. He was meticulous and professional, and our windows sparkle. I would highly recommend Matt.

WOW WOW WOW!! Matt at Black Diamond Window Works did an amazing job. He was professional, informative, fast and detailed detailed detailed! I will only use him moving forward!
