Santa Clarita, CA
I had several windows replaced in my home by OK Mfg & Supply. They worked with me to choose the best windows within my budget. The installation was done in a timely manner by very courteous and knowledgeable installers. I never had a problem with any of the windows, so several years later, I returned to OK Mfg to purchase some doors and some more windows for the rest of my home. Again, I was very satisfied.
