We worked with National to help my son on his Eagle Scout project. Lance was awesome to work with and helped us tremendously. Here is the final product. 11 picnic tables for a local high school and their outdoor classroom. Thanks Lance and National!

Called a bunch of lumber yards looking for 4x4 that I needed cut to size. Most places have the material but will not cut for you. Called this place and they not only cut to size but when I showed up with SUV to transport 4 14ft 4x4 they said where do you live, I said Shelton. They said oh we have a job tomorrow morning in Shelton so we can deliver for free since we are going out there. How nice was that?!?! OMG deliver 4 pieces of wood, $100. Bucks of supplies and you are offering to deliver for FREE. I wasn't gonna be home and they said that's ok we will drop them where you want them

A very good lumberyard. They specialize in construction lumber so they don't have any fancy figured woods or exotic species for woodworkers. But if you're building a house or a deck, then they'll have what you need.

Prices are moderately good but quality is much better than what you can get at Home Depot. Their wood is much straighter and their pressure-treated wood is much dryer than the big boxes.

Their staff is friendly and helpful. Good all around. I just wish they had more exotics for my woodworking.
