Got a tiny nick in the windshield that had to be treated before it started to crack. Called my trusty car mechanic(Don’s in the Mission) who referred me to A-1 Glass off Bayshore who put me in touch with Greg Thomas who operates his business totally by phone out of his roaming truck. Don came out an hour later and spent at least 40 – 45 minutes treating the windshield and charged me a very reasonable rate considering convenience of a house call and quality of work. Don is very personable and went about his procedure while we chatted. He was very thorough and knew exactly what he was doing, having been in the buisness for many years. Glad A-1 recognized him as a great source of mobile repair, they knew what they were doing and so did Don. Highly reccomend.
