    Hands down the best contractors in town. From start to finish, their team was incredibly helpful and professional. They completed my project ahead of schedule and stayed within budget, which I really appreciated. MCW did an amazing job with my home remodel and the installation of a new outdoor steel pergola. The fabrication and welding work is truly top-tier. Big shoutout to everyone at the shop for their hard work and dedication!

    I’m sharing my experience regarding a chair order connected to Richard von Saal and handled by Mario Construction and Welding. I did not authorize any charges on my credit card related to this order, yet my card was used. I also was not involved in approving, reviewing, or making decisions about the chairs at any point. While I may have been present in a general capacity, I had no role in the order, approvals, or transactions. There have been statements suggesting that I approved work in person or was actively involved in the process. That is not accurate. I did not provide approval, and I was not involved in managing or overseeing this project. Mario is lying saying I was there and approved this in person with my credit card. That is a lie. Where are the cameras to prove I was there authorizing this charge? It's one thing to use my credit card and not have approval but to lie and say I approved the charges in person is unacceptable. I strongly recommend that anyone entering into agreements ensure all authorizations and approvals are clearly documented in writing. I am currently taking steps to resolve this matter.

    I had a small welding project and Mario got me in the same day. He finished within a few hours and called me to pick up my parts. Mario is very personable and willing to help out!
