- MKMike KAug 14, 20265.0Rob and crew did amazing work installing a glass block window in a shower in my older home. I mostly wanted to fix a problem - a vinyl exterior window in a shower... Rob took out the old one and installed a massive and beautiful glass block window that gives me more light and seals up the leaks. I am so happy with every step of the process working with Rob. The new window has added value to my home, something I was not expecting at all but am very happy about. There is a reason these guys are busy - they do excellent, top-notch, highly skilled work and do it affordably. I am very happy with the work and recommend Rob and Glass Block Baltimore in the highest terms. You will be happy you hired them.
- LPLavina PetrosJul 31, 20265.0If I could I would give this business 100 stars! Rob and his team went above my expectations! Rob is extremely knowledgeable about his craft! Highly recommended
- CSCharles StoneMay 28, 20265.0Rob and the crew showed up on time. They removed the old windows and installed these nice, new glass block windows. They cleaned up and we're on to their next job in one hour. They exceeded my expectations and I am thinking about replacing the rest of my basement windows with glass block. Glass Block of Baltimore is an excellent business and I highly recommend them to anyone who maybe considering the switch from conventional windows. Thank you Rob and crew!
- GGglassmansmoothApr 22, 20265.0We were looking to replace our basement windows and got estimates from several companies and various styles. We called Glass Block of Baltimore and got a call back from Rob within 5 minutes. Rob is a very matter of fact guy and knows his craft and is very caring about the industry. After comparing all of our offers we decided to go with glass block windows. Rob was great every step of the way and kept us informed when the windows would be finished and installed. He was accurate to the hour. He and his crew came out and competed everything in one day. Great quality, very knowledgeable and personable and very good pricing made this the right choice of window and company for us. The windows look great and allow so much light in the basement because we don't have to use curtains on them. Rob confidently said if we ever have an issue it would be taken care of immediately but you won't have an issue with these windows. I would highly recommend Glass Block of Baltimore. L.Williams
