I would give an additional star, if they had one! Mercedes communicated timely about Kevin's arrival. On arrival, Kevin and Nick got down to business straight away. They both were professional, and had the courtesy to wear shoe covers (don't see that with some of the other guys). Kevin was very reasonable and saved me $$. They were done in less than an hour for multiple fixes - door bell, 5 smoke detectors, kitchen disposal switch issue. Kevin diagnosed all the problems in a flash, and fixed it pretty quick too! He is tech savvy too and explained the break-down of the bill on a cool tablet he carries. Very nice family feeling, with no pressure.
