Landscape Contractors

Spiers Construction started installing retaining walls, about 35 years ago, back when other Boise companies didn't want to bother with them. We have installed concrete, block and rock walls all over the Treasure Valley. 

We have built retaining walls where others wouldn't even consider working. Several of the locations are on steep slopes or in areas difficult to work. Please take a minute and browse our Image Gallery.

Retaining Wall Contractors

Darren Spiers has worked with landscapers on hillside homes and branched out into placing large and small rock on property within the Boise foothills. He is a skilled craftsman on sloped or stepped landscapes, as well as installed outdoor steps. We offer Sandstone from our own quarry. We also bring in Arizona cut stone for fountains and water features. 

One of the more prominent projects that Spiers has worked on is the Anne Frank Memorial in Boise on 9th Street. We furnished and placed most of the stones.

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.

Brad Deegan

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.

Nampa, Idaho

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.
