My team and I at Blue Mountain Builders have been using Marks Lumber on almost every home we have built the past 5 years. Their staff is professional, polite, and very knowledgeable. We use a variety of their products such as siding, flooring, shiplap, and large timber post and beams. The materials are usually great! The few times we have had issues arise Marks Lumber staff has corrected or replaced the problem products promptly. It is great to have a local supplier for these rough-cut items. We will continue to use Marks Lumber on our future builds for many years to come!
