re: Load bearing wall removal

Any contractor that does remodel or home building can do this OP. As said its not necessarily difficult, its fairly basic framing actually. They will likely essentially build a temporary wall on either side or one side of current wall, tear out the current wall, and then put in beams.

Depending on the situation, its likely the contractor has an engineer spec out the work.

Definitely not DIY type of situation for 99% of people. But all a contractor is going to do is bring in someone to prep/ demo, bring in a framing crew, bring in a drywall, crew, and you are basically done.

One thing they may have to do depending on your situation is support the posts with better footers. Which means potentially adding a cement footer if its slab or additional supports whatever that is called if its 2nd floor or pier and beam.
