I was looking at a 100 year old house today. The hardwood floors are
buckled quite badly. The floors are located above a crawl space with no
vapor barrier between the ground and the flooring. I'm not even sure if
there is a sublfloor at this point in time. I realize the first thing
to do to attempt to solve this problem would be to install a vapor
barrier over the basement floor to stop the moisture. I also realize
that the floor is not going to magically settle itself once the
moisture problem is solved since nails were likely pulled, boards
warped and whatever else. I'm wondering if anyone has had to deal with
a similar problem during a rehab of an old house and what some possible
solutions might be. I've heard about getting at it with screws from
underneath (if there's a subfloor) and/or nailing screwing from above.
Any advice would be much appreciated, thanks in advance.
