For many many years, I've been returning to Mr. Handyman to have them do work in the restaurant I manage. We call them in for all sorts of things (especially things that require attention to detail)-- hanging items, minor building repairs, work on stairs or corners, utility assembly, sink installation, etc.
Their service is great; the employees are always very professional, friendly, and knowledgeable about their work. They're not always perfectly on time, and I have, at times, had to have some work redone, but (I wasn't charged, for the second time, and) all in all, they're definitely one of the best repair companies I've come across.
