"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

Lally columns are named after their founder, John Lally, who owned a construction company in the 1800s. He invented the columns as a means of providing temporary support for beams and rafters in homes his company was renovating. The original Lally columns were also made of steel, although the inventory used a thicker gauge metal, which provided additional support for larger projects and long-term structural solutions.

The difference between a lintel and a beam is what loads each is responsible for supporting. A lintel is a type of beam that is responsible only for supporting the load above an opening, such as a window or door, and transfers the weight to the side walls around an opening. A beam supports the slab and transfers the load to nearby columns, which then disperse the load to the ground.

No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.

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 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
