What are Property Preservation Services? Property preservation service contractors are in the business of maintaining and repairing damages to the interior, exterior or landscape of a vacant, foreclosed, or default residential property. The property may or may not be occupied. We provide services for homeowner associations (HOA), condo owner associations (COA) and municipal codes and requirements. Our property preservation service for residential properties include maintaining the yard, sprinkler systems, landscaping, and conducting regular as well as seasonally required maintenance.
