Ryan is a very helpful and honest guy. I explained my problem with the garage door making some loud noises after not being opened for a few days. He told me that it was likely being caused by the vinyl weather stripping becoming glued to the door and the noise comes from the forceful separation of the two surfaces. He recommended I use Vaseline or Pam on the vinyl surrounding the door on the sides and the top.
Ryan could have charged me a service call to come out and do this but he gave me this tip over the phone at no charge. I will certainly be using him when other problems arise.
