In the effort to ensure the quality of the vendor and the repairs, Zenith requires trade licenses and current proof of insurance from all of our vendors. Zenith strongly advises using our highly skilled vendors for any maintenance and turn work. If a property owner insists on using their own company to service their rental property, it is necessary for their vendor to provide the same documentation we require. In the case of after-hours or emergency calls, Zenith contacts our primary on-call vendor.
