Pre-Lock were very professional and customer service oriented. I left a message late in the day about a (non-urgent) broken front door latch and Drew called me back at 9:00 a.m. the next morning. I emailed photos of the mechanism and arranged for a service call at 9:00 a.m. the next day. Boris arrived with the right hardware and worked quickly to install the new parts. He was very polite and personable. I would recommend this company without hesitation.
