About Us



Established in 1973
Owners: Darren, Tristen and Aiden Spiers
In the fall of 1973 the Treasure Valley was going through a building boom. Keith Spiers, at the time was 34 years old with a wife, 2 sons and a third on the way. Keith saw himself in a dead end job with no future and decided to take a risk going into debt on his first piece of equipment. Keith worked daylight till dark 7 days a week to stay ahead of the demand. With some good advice and encouragement from friends, his determination and hard work paid off. Keith had built Spiers Construction into three separate divisions, commercial, residential and concrete.
Since Keith’s retirement Darren Spiers, Keith and Marsha’s son has predominately ran the business. At that time the choice was made to liquidate the concrete division to focus on the residential and commercial divisions and to this day they are stronger than ever.
​
The beginning of 2024 Darren decided he was going to retire and has instilled his trust in Tristen and Aiden to take the “wheel”. Both Tristen and Aiden have grown up in the construction business with their Grandpa and Dad at the helm. Now Tristen and Aiden run Spiers Construction as the legacy their Grandpa has built for the Spiers family. This being a 3rd generation construction company means the world to them, and they will uphold the same mission Keith always had, “always do it right and deliver more than expected”.
