Last week our team worked on a project in Prospect CT. The project covered a full scope of work, including installing a new septic system and safely removing an in-ground oil tank. The job also involved removing stumps, as well as removing construction debris, and preparing the property for future use. We wrapped it all up by rough grading the backyard to ensure a solid foundation for upcoming landscaping. We left the site clean, neat, and ready for the next phase.
