I was very impressed with Michal from Custom Exchange, Inc., he came in and did a quick assessment, it took about 10 minutes, and he gave me exactly the information I needed. I had 3 estimates from different companies, and Michael's was the lowest. It took only about a week or two to get the job started. The gentleman Robert, who did the installation, did an professional and efficient job. There was only one thing that happened. I forgot to tell Michal about the lock on the back door, and he was able to take care of it quickly so it wasn't really a problem at all. I would definitely use them again and would highly recommend them to anybody!
