Surprised with the poor reviews on here. Mike was great! Scheduled the repair for 2 large glass patio doors and was expecting to pay over $250 for new rollers. Mike showed up on time, fixed both doors, only charged $95 and gave me good advice on maintenance. Both doors now work great! Mike really knows his stuff. My only "complaint" is that being a one-man business, he has to schedule things out in advance so a quick-turn repair is unlikely. I would definitely call Mike again for future repairs.
