Will a landscaper damage my neighbor’s property?

They shouldn’t. Reputable crews set clear access paths, mark property lines, and place protective mats for equipment. If any work may affect a neighbor (noise, dust, temporary staging), the landscaper should notify you so you can give your neighbor a heads-up. In Utah, licensed contractors carry liability insurance—ask for a certificate issued to you. If a fence post, sprinkler, or surface is damaged, the contractor should document the issue and repair it quickly. Put access areas and restoration obligations in writing before work begins to prevent disputes.
