I telephoned Garage Door Repair Dallas TX because I got worried when our garage door suddenly closed by itself just right after my husband drove off. It was the first time I encountered such incident that I really panicked. The kind representative who took the call reassured me that their technician was on his way. The tech was polite and skillful. It turned out that the torsion spring broke and replacement was a must. He has complete tools on hand so he was able to finish everything in just a couple of hours!
