30 years of garage door repair. Garage doors and garage door openers are my gift and all questions are welcome, but results are not alway guaranteed. Some problems require a home visit, and I'm not leaving Alaska without a two way ticket,:whistling2:So sometimes the right answer is DON'T. But questions are free so ask as many as you like and I will try to answer as simply as I am capable. Sometimes the instructions are not simple but I have learned that interpretation is nine tenths of the law. I know every job is an emergency so I will check as often as I can.
