What Our Customers Say

Ethan G.

"Don't judge the store by the exterior shabby look, this is a little diamond in the ruff!

Their prices on lumber are great, and their staff are very knowledgeable on every question I've ever had!

If they don't have something in Stock they can get it within 24 hours.

I'm shopping here at least once a week."
