Olsun Electrics had TDS Doors install new Aluminum frame windows in the front office 4 years ago. from that time there have been many issues with these windows. with leaks and moisture. it has been so bad that Olsun has replace the window trim once and is in need to do this again. we have tried several times for them to come over and look at these window ad see what needs to be done to fix this problem. TDS door will not even return phone call or e-mail request. I cannot recommend them for any door or window work. Sincerely Olsun Electrics
