Cascade Lumber is absolutely the BEST place for lumber and building materials. Everyone at Cascade Lumber has stellar integrity, is extremely professional, responsive, and helpful. Their prices are also the best around out of a dozen estimates I had gotten. We had a very big project and bought lumber for a +5k home.Their quality of lumber is supreme and we were left very pleased. Chris has a keen eye on what material we needed, when we needed it, and what typically happens in the field in terms of material usage. All materials were delivered earlier than anticipated and orders were complete. I was not an easy customer to deal with by any means and Chris went above and beyond the call of duty to help me with my project.At this point in my project I had gotten to work with multiple other suppliers and quite a few (at least 50% of them) have some shady business practices. In contrast Cascade Lumber has a very open business approach and high standard of practice. I highly recommend them!

Very good staff. They move to the counter quickly to take care of their customers. Competitive on some lumber expensive on others, call around for prices before committing.10' 2x8 boards were spot on, but 7/16 OSB was $36+ where the big box stores were $30-31.14" 2x12 pressure treated was $61, it's $51 in Arlington and $43 in Southern My Vernon. Sometimes it's worth the convenience to buy there sometimes it'll be worth a longer drive.
