Sometimes it's hard finding contractors to work in the mountains, but this is where we thrive. We can build a road to your cabin, clear the building site, & move some dirt. Grading, stormwater design, and erosion control can all be done by Spiers.

Shannon White

Garden Vally, Idaho

Thank you to the Spiers team, they were masters at moving dirt and rock, digging trenches and rebuilding the runoff areas of our property. I know Mike usually does commercial projects but we are so glad he was assigned to dirt removal. Also appreciate the timeliness of the support they received in equipment operators to haul off debris and deliver gravel.

Darren Spiers is owner, and I have had pleasure of working with him on two jobs. Always available (via phone), flexible, and fairly priced. All his crews also have the "I like working for Darren" attitude when on our property. I highly recommend.

Eagle, Idaho

I hired Spiers for a private road and lot excavation I needed into my cabin north of Featherville, near Pine. No way was I going to build a road on the steep mountain. Even after the horrendous deep snow, my rockwall landscaping and grading made it thru the water melt off.

As a home builder in SW Idaho, we depend on Keith Spiers and his expertise of septic systems. They design our drainage and install the concrete septic tanks. We also use them for bulldozer and backhoe work. One of the best of Boise.
