Love this place! Great quality and great service. I bought some sheeting and 2x6 material from another company over the weekend because Golden Rule was closed, and I was reminded of why I don’t go anywhere else because the quality and service were very poor. I recommend Golden Rule Lumber all of the time.

This is unquestionably where you need to shop. Honesty, integrity and above all you'll know that you are appreciated as a customer and as a person.
I will finish this build with Golden Rule and everything i do from here on.
