"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

Welding is the process of using extreme heat—and, sometimes, pressure—to attach two pieces of metal. In contrast, metal fabrication is a more involved process that can include welding, sheet metal work, bending, and other forms of metal manipulation. Metal fabrication is a large-scale project that may or may not involve welding, while welding is more often a step in larger fabrication projects.

The cost to weld aluminum averages about $14 to $22 per pound. The type of metal factors into the overall cost of any welding project due to the cost of the materials and the expertise required to work with it. Some of the most common metals used by welders include:

  • Magnesium alloy: $7–$16 per pound

  • Low-carbon steel: $11–$12 per pound

  • Stainless steel: $13–$15 per pound

  • Copper/brass: $24–$29 per pound

  • Cast iron: $38–$79 per pound

  • Titanium: $60–$85 per pound

Professional metal fabricators typically charge around $70 per hour, but the total cost of your project will depend on several factors. The largest cost drivers are the size, complexity, and design of the project, as well as the price and type of metal used. A good way to estimate the total cost is to multiply the cost of raw materials by four; typically, one-quarter of the total goes toward materials and three-quarters toward labor. Your geographic location can also influence costs, as labor and material prices vary by region.

This all depends on the tools you have on hand and whether you’re trying to cut a straight line or shapes. 

The best tool to use for straight lines is either a circular saw or table saw. When cutting shapes, a jigsaw will be the easiest and most precise tool to use. 

There are a few things you can ask welders before you hire them to get an idea of their experience and ability levels:

  • Are you licensed and certified?

  • How long have you been in the welding business?

  • Do you commonly do the type of welding I need?

  • Do you offer any kind of warranty for your work?

  • Do you charge by the hour or by the project?

  • How long do you expect my welding project to take?

  • What steps do you take to minimize errors in your work?
