Testimonials

On 6/17/2025 Jordan Giesemann had this to say:
Sure, TSBS supplies contractors, but the retail options for home builds and home renovations are exceptional. Personal consulting from beginning to end, TSBS will help you build your project of any shape and size

On 5/8/2025 Matt and Christi Johnson had this to say:
By far the best contractors supply store in town. The staff is very professional, knowledgeable and friendly. I highly recommend using them as much as possible.

On 11/14/2024 Travis Saunders had this to say:
I recently attended a contractor luncheon at Tri State Building Supply, and I was thoroughly impressed. From my first impression on-site to the experience in-store, it was clear that this company values its community and customers. They currently have job openings that are definitely worth considering—if you're looking for opportunities in the building supply industry, you would be crazy to pass this up! The staff are friendly and knowledgeable, and they genuinely care about helping employees, contractors, and homeowners alike. Whether you have questions or need specific materials, I believe you'll be well taken care of at Tri State. I look forward to establishing a strong working relationship with them. Another great perk is they support #DEWALT and #Milwaukee. They are not afraid to set you up before the project begins.
