Having a brother in the heavy equipment excavation industry provides an excellent asset to all customers who have large-scale projects that require multiple pieces and varieties of equipment without having to deal with multiple contractors.

And references are extensive.  Our reference page list is only a small portion of our satisfied previous customers are now offered an “open floor” to provide testimony regarding their experience with Tri County.  Simple still works here.  Value and integrity.

We also provide references to additional local trades as well as outside third party trades which specialize in a variety of construction skills from engineering to more tech-specific trouble-shooting.

We are so confident in the product we request our customers to view an instructional video and see for themselves how simple still works in the wastewater industry in both residential and commercial installations.

To close, we want everyone to know we are here to help our neighbors and provide expert attention to their diverse construction needs.
