"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"Frank and Nick did an excellent job replacing a window, installing snow guards, and completed roof repairs to make the house weathertight for me. They showed up when they said, worked very efficiently and got everything done quickly. Pricing is very fair and quality workmanship. I have used F.B.I. a couple times now and know I will use them for future projects."

"Other than delay due to wet weather, this company was great; very patient with our trying to decide the "right fencing", communication was very responsive, and while on our property the two man team worked very hard, respected our privacy, and left the project with everything cleaned up. Would have them back anytime."

Welding questions, answered by experts

While a high-speed circular saw will cut through metal, and even cut through multiple sheets at once, the fast-spinning saw blades create a lot of heat. This heat can damage paint and other protective coatings, leading to serious problems like rust over time. The cost to paint a metal roof again to avoid this damage is typically an additional $0.50 to $1 per square foot.

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

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

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.

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?
