I have a multi level townhouse which I am renovating as the housing prices
are ridiculous where I live. One thing that bothered me about the place is
that there was a sag in the kitchen floor. I had planned to either put down
some ceramic tile or perhaps hardwood flooring, but, with the sag, I would
have to level the floor somehow. The easier option would be to use some
sort of levelling compound, but, I decided to investigate the possibility of
lifting the floor from below. I gained access to a crawlspace which allowed
me to view the area under the kitchen. As it turns out, the wall between
the kitchen and dining room as well as the master bedroom wall upstairs lie
on a 14 foot cantilevered beam 32 inches out from the foundation. No wonder
the floor is sagging.
My options seem to be as follows:
1. Ignore the problem, fill in the sag, put down flooring.
2. Jack the beam up and put in a support in the garage.
Option 1 would seem to result in problems down the road. Option 2 would cut
useable car storage space. The difference between the location of the
upstairs walls and the foundation is 32 inches.
