At JW Services, we provide solutions for all general excavation needs. We are equipped to handle all kinds of small and large projects. Whether you are looking to install a new septic system, a foundation for your new home, or you need another earthwork solution; we are equipped to help.


We provide large earthmoving services using scrapers, dozers, and blades for site development, leveling, and grading.

Roadway Construction & Repair

Our roadway construction services include building, grading, leveling, and graveling roads for rural areas. We can also maintain roads that need repair, and we install approaches, culverts, and cattleguards.

Septic System Installation

Installing a septic system requires heavy equipment, a qualified septic tank, a leachfield design, and a construction permit. We have installed many septic systems and can provide you the expertise needed to install your septic system.

Foundations & Basements

We can provide excavation services to get your new home ready for a foundation, basement, or crawl space. Grading, leveling and preparing the site before the concrete are essential to ensure proper water drainage.
