Gilcrest Jewett Lumber has been known as the homebuilding headquarters for over 150 years. Their experienced design team at Plum Building Systems custom designs and builds all our truss and floor joist systems in every home. All of our lumber material,  decking and interior trim materials and doors comes from Gilcrest. They have a huge show room located in Waukee!
Call 987–3600 and ask for someone in  their marketing department? I was given to email, which I did.
