Client Reviews
"NWS did an incredible job modifying our shipping container into a fully functional site office. Clean welds, solid work, and they communicated every step of the way. Highly recommend."
"Had two trailers that needed serious structural repair. NWS came out, gave us a fair quote, and knocked it out fast. Both trailers are back on the road and holding strong. These guys are the real deal."
"We needed a container turned into a pop-up shop with service windows and an awning. NWS nailed the design, the timeline, and the budget. Can't say enough good things. Will use again for our next location."
"Called NWS for an emergency weld repair on our yard gate — they showed up same day and had it fixed before end of business. No runaround, no excuses. Just got it done. That's rare these days."
FAQ
We're based in Baytown, TX and serve Harris County, Chambers County, Jefferson County, Liberty County, and surrounding areas. If you're not sure if you're in range, reach out — we'll tell you straight.
We typically respond to quote requests the same day. Depending on scope and schedule, we can often start within a few days. Emergency repairs get priority — call us directly at (409) 273-0373.
We primarily focus on modifications and repairs. If you need a container sourced, we can help connect you with trusted suppliers. Once you have a container, we handle the rest — from simple door installs to full custom builds.
Every project is different. A single roll-up door install is different from a full office build-out. Send us photos and details about what you need — we'll give you a clear, honest quote with no hidden costs.
We offer mobile welding and can do a lot of work on-site. For more complex modifications, it may be more efficient to work at our location. We'll recommend the best approach when we quote your project.
We focus on the fabrication and welding side. If your project requires permits or structural engineering, we can advise you on what's typically needed and connect you with the right people.
