Foundation Excavation Services | Mariner Property Services

When building a new home, garage, or addition, the quality of the foundation excavation determines the long-term stability of the structure. Mariner Property Services provides precise, reliable foundation digs throughout Castine, Blue Hill, Bar Harbor, Ellsworth, Foxcroft, Bangor, and Bucksport, ME. Our team understands the soil conditions, elevation changes, and drainage requirements that are essential for strong and secure foundations in coastal and inland Maine building environments.

Successful foundation excavation requires more than just digging to a depth. It involves careful planning, site evaluation, measurement accuracy, and coordination with your builder and concrete crew. Our approach prioritizes stability and level ground, ensuring the site is fully prepared for footings, frost walls, slab foundations, or crawlspaces.



We tailor each dig to the property’s layout, the structure’s design, and local building code standards. Whether you are building a year-round residence, summer property, lakefront home, or structural addition, we make sure the ground is properly prepared for a long-lasting foundation.
