Angelina, sales associate, provided excellent product knowledge and advice regarding products that would meet my requirements. Angelina highly recommended the insulated doors, I did get the insulated doors and very pleased. I hsd difficulty prtogramming my garage door opener and when I contacted them for assistance they arranged to have service technician Ronnie come to my home to help. Ronnie explained what was wrong and what he needed to do to correct the problem; nothing defective with the opener. In the future I'll know how to correct any issues. Everyone at King Door is awesome to work with and their lines of products are quality. - Jim P.
