I've been a client of 5 Star for over 5 years. I used them at a previous building of mine & switched to them when I became a Resident Manager at another building. We have one regular technician (Phil) who comes to our building every week without fail & is very reliable & extremely thorough. I don't like companies who send a different guy every week as they don't know of any problems we've encountered or what or how things have been treated in the past.
