When i bought my house three years ago, i was told i needed to put in 6 more beams in my basement to prevent the walls from bowing in anymore. Though it hasn't got much worse since, i got an estimate to put in more beams. I have two already on the wall on the left but none on the other three walls. The basement guy who came out said they should be no more than 6-8 feet apart to be effective however the one wall with only two seems to be fine. So the estimate he gave me was for 12 beams because of the size of my basement. Will i be okay with just two on the other walls a piece or is he right on saying 6-8 feet distance is necessary.
