"I’ve had Randy Zack and Connor. Do multiple tree removals on my house. They show up on time clean up and do great work. They’re very fairly priced considering you get very high quality work. They’re great guys who are professional kind and take pride in their work. I would hire them first for my future projects."

My company offers many services including and specializing in tree removal and tree pruning. I offer free quotes. I'm an owner-operator so if I'm hired I will personally do the work.

Welding questions, answered by experts

Steel I-beams are an increasingly popular choice for supporting a structure because they support a large amount of weight with a small profile and without the need for load-bearing walls or supports underneath. This allows for more open floor plans, which most people tend to prefer. They also resist fire, pests, and rot and last for the lifetime of your home.

Beams made out of traditional lumber can often only span 8 to 12 feet without requiring vertical supports, so if you want a wider opening to create a more open floor plan, you might need an LVL beam. LVL beams can span up to around 30 feet without the need for load-bearing walls or vertical supports underneath, making them a better option for keeping your home as open and airy as possible.

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

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)

Some states require welders to be licensed and certified, while others don’t. However, it’s always a good idea to hire a licensed welder, regardless of requirements in your area, especially if you need welding for structural components of your home or gas lines. Licensed welders have gone through training and testing to prove their skills, so they’re less likely to make a mistake that could be detrimental to your home. Use Angi’s state licensing tool to determine whether your potential hire has a welding license.
