I have used American Best Door Service in Plano a couple of times and would highly recommend them. Allan is very knowledgeable and quickly fixed my problems, whether it was a door out of alignment or the installation of new springs. While it is important to have a competent tech, it is just as important to have someone who you can trust to give you an honest diagnosis and a fair price. I never felt like I was being sold something I didn’t need or that the price was out of line.
