Which Maintenance Contractors Does a Building Need First?

Start with what law and safety require: fire protection, elevators and backflow testing where they apply. Next cover what is costly to fail: HVAC and the roof, each serviced at least twice a year. Then line up a plumber, electrician and locksmith before an emergency, and consider one facility maintenance company if you have little staff time.
