Placement of support columns under a single floor home?

Question

I have a 24x60 single floor ranch style home and I want to beef up the main support beam because it is sagging.

How many feet apart should I place the support columns?

Thanks.

Answer 1

One support column could be enough.

Consult with an engineer or architect.

Obtain a building permit.

Answer 2

It depends on the load it is carrying.  There are charts to determine spacing requirements for support beams.

Answer 3

This is difficult to answer without knowing the dimensions of the main beam.   I suggest you have an architect or engineer have a look.
