"Erik was very prompt in responding to my request for bids. He was able to start only days later. The handrail he built for my porch steps matched the existing porch railing and he attached it firmly to the stone steps. Prompt, quick turnaround, quality work, very pleasant to deal with. And did I mention about half the cost of the other bidders?"

"We found a speck home being built by Baker Builders. We went under contract just in time to pick out all of the finishes. We worked primarily with Travis, who was great to work with. He communicated well on any changes, delays, or issues. At the time we were building there were several supply chain issues, so we had to make some changes along the way. Travis always provided an alternative or solution anytime we needed to make a change. The house turned out beautiful! We are very happy with our custom home."

"My gate and part of my fence were destroyed by the Marshall fire winds. I got quotes from several contractors, including how they would approach it so that even in future high winds it would be very sturdy. Luke's design idea was better than all the rest. He and his helper rebuilt it in a day and it is incredibly sturdy as well as aesthetically really nice. The price was a bit higher than other contractors, but the quality was superb."

Welding FAQs, answered by experts

Since water heaters are primarily made of metal, they’re commonly accepted by scrap yards and collectors. Don’t expect to fetch a high price, though—water heaters are mostly steel and aluminum, which aren’t high-value metals. Some components are made of more valuable metals, like brass and copper, but they’re a small portion of the heater and won’t affect the price much.

Yes, but you’ll need reliable steel-cutting tools and safety gear to get started. Shipping containers are typically around ¾ inch thick, so it’s entirely possible to cut through them, but experience and the right equipment are very important. When possible, try to get a container as close to the size you want it as possible.

Cutting rectangular ductwork requires careful measurements and the right technique. Use a measuring tape and pencil to mark the cutting lines accurately. Tin snips are excellent for straight cuts on smaller ducts. For more extensive or thicker rectangular ducts, a reciprocating saw with a metal-cutting blade is effective. 

Ensure the duct is well-supported and secure while cutting to prevent wobbling and maintain precision. After cutting, use a metal file to smooth any sharp edges, ensuring safety during installation. 

To maintain custom or fabricated metal structures and extend their lifespan and appearance, perform regular cleaning, apply rust prevention treatments, and use protective coatings.

Some welding projects, such as repairing pipes or fences, require travel, whereas others, like furniture repair, do not necessarily require the welder to come to you. Travel and overhead factor into the overall cost of your welding project. Some of the most common welding projects include:

  • Metal furniture repair: $35–$100

  • Pipe repair: $200–$1,000

  • Small gates: $550–$750

  • Fencing: $1,200–$1,800

  • Fabricated sheet metal welding: $750–$2,500
