| Well, I am in a dilemma. Bought an old House, 1905, gutted the 2nd floor bathroom and would like to put a cast Iron tub in. The tub with water will weight about 500lbs. When ripping out the bathroom, the subfloor , which was diagonally placed 2 x 6s that went from one room to the other, have been taken out. The floor joists have large holes from old plumbing plus holes for new plumbing. I am worried that the diagonal subfloor boards did more then act as just sub flooring, but distributed weight to a larger surface making less load in the bathroom...
Can I sister the joists and call it a day or should I think about something more invasive. This problem has been keeping us from moving forward. Thank you in advance. J |

| A lot depends on the joist depth (top to bottom dimension) and the span, along with how large the holes really are. There are 'standard patches' for certain size joists made of sheet metal that can be nailed on even if the pipes are present. If the holes do not contain pipes, you could sister to the same size as the joist was originally, but could still have problems if the joists are considered undersized. While old work is grandfathered, once you start making major changes the grandfathering usually goes away and repairs must be made to the code in affect now. |
