Client Success Stories & Testimonials

Here’s how fellow Washington-area customers achieved their project goals with us

Jeana Shelton

Building a new home and have used Hall Brothers for much of this project. We have received the most helpful, friendly service from everyone there. Specifically, Lynn has been so kind and easy to work with on our Onyx purchase! She’s made it a breeze and went over and above normal customer service. Also, we price shopped this Onyx purchase at Hoods, Lowes and Menards and Hall Brothers beat all of them by $400. So this is the place to purchase your Onyx!

Terry B

Great Place! I can’t say enough good things about Hall Brothers. We built a home last year and Hall Brothers furnished most of the materials to build our new home. From beginning to end Dave, Mark, Jim and the rest of the team at Hall Brothers helped in the decision making process of trying to build a home with quality materials while keeping in mind sustainability and cost. We also loved that they carry Benjamin Moore a good quality paint which we need with two kids. We highly recommend Hall Bros!
