Cities We Serve / 02
From Boise to Melba and Everywhere Between
Boise & Garden City
Our home turf. From North End sewer line replacements to full excavation and site prep for infill builds, we handle Boise's mix of older utilities and new construction every week. Garden City's riverside lots bring high groundwater, and our drainage and dewatering experience keeps those projects moving.
Meridian & Eagle
Fast-growing Meridian and Eagle keep our crews busy with building pad prep, utility trenching and water line installation for new homes, plus drainage corrections where new landscaping meets Idaho clay. If you need an excavation contractor near Meridian, we are minutes away.
Nampa & Caldwell
Canyon County is where much of our septic work happens. We install, repair and replace septic systems and drain fields across Nampa and Caldwell, and our familiarity with county permitting and local soils keeps installs on schedule.
Kuna & Melba
Rural properties around Kuna and Melba rely on wells and septic rather than city services. We build and repair the whole underground package: septic systems, water lines, and the grading and drainage that protect them.
Star & Middleton
New builds and acreage properties in Star and Middleton call us for site development, foundation excavation and sewer or septic connections, done right the first time so the ground never has to be opened twice.
Emmett & the Outlying Valley
We regularly travel to Emmett and the surrounding areas of Gem County for excavation, septic installation and water line work. If you are anywhere in Southwest Idaho, call and we will tell you straight whether we can get a crew to you.
