I called TCB on Monday and left a message requesting an estimate to replace my old basement windows with glass blocks. Otto returned my call within 15 minutes. He came out on Tuesday to give me an estimate and I was lucky enough to have the glass blocks installed on Thursday. The guys did a great job. They put down tarps to cover my carpeted stairs and on the basement floor. I love the new windows. I did not get a chance to thank the two guys personally, so I would like to have Otto thank them for me. I would definitely call TCB again for any future repairs. Thanks again Otto for a job well done!5
