Do any of these companies clean around the clock?
Around-the-clock availability is stated by 3 of the 15 commercial cleaning companies here. In this trade that usually means an emergency call out for a flood, a burst pipe or a biohazard rather than a crew standing by, so ask what the out-of-hours number actually reaches.
