"James was exceptionally professional and polite and did an outstanding job on the rails that he installed in my house with both the backyard and the front. He’s a perfectionist and I will hire him and re-hire him over and over and recommend him over and over. Very humble and a very soulful human being. I give him 10 stars not five. Thank you, James for the wonderful professional job. :)"

"Michael is very honest, hardworking and meticulous in his work. He is well versed in his field, which includes every area of construction. I have a home built in 1922 which needed a lot of work. Michael understands and appreciates the value and charm of older homes. He worked with me to restore what he could and repair what would be too costly to restore. He keeps to his word on when he will be there to do the work and does not change the amount he quotes unless I ask for a change."

Welding FAQs, answered by experts

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. 

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

Your typical household tools will not cut a metal pipe. To cut a metal pipe, you’d need more specialized tools like a pipe cutter or circular saw. Do not attempt to use these tools without taking proper safety precautions and wearing safety gear. It’s usually safer to let a pro cut a metal pipe, especially if you’re not confident in your skills with a heavy-duty saw.

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. 

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.
