Why LandscapePros in St. Maries

Backflow Testing & Repair built for Benewah County ground

The St. Maries river valley creates a landscape of incredibly rich, silty bottomlands and dramatic, timber-choked bluffs. We provide excavation for flood-conscious site planning and road building through the dense, moist soils that characterize St. Maries and Benewah County. We often use specialized mats or wide-track machinery in St. Maries to prevent our equipment from sinking into the soft riverbank silt while we're setting foundations or clearing brush.

That local read is the part that matters. Every backflow testing & repair job we take on in St. Maries starts with the same discipline: read the soil, read the drainage, and read what the freeze-thaw cycle will do to the finished work three winters from now. Family-owned since 2005 and still run by the Gladish family — the same crew that walks your property is the crew that builds it.
