Our 4 foot crawl space was flooded with Sandy last October. The water came all the way up to the floor joists but never hit the bottom of the subfloor of the wood floors on the first level. We do not see any of our wood floor or subfloor buckling but we do notice increased squeaking of our wood floors when walked on. We always had some level of squeaking in some areas before the storm, but the Squeaking seems to occur to some extent no matter where we walk on the floor. Do you think we need to be concerned since our joists were partially submerged and soaked for at least 9 - 10 hours? Should we be considering replacing the any part of the first floor or is there another alternative in eliminating the squeaking? Thanks for any advice.
To eliminate any concern, you should keep your eyes open on that area. If it dried out properly, maybe you'll have no problems. But someone is going to have to wait and watch and see if a problem develops.
As for the squeaks, they usually are fairly easy to eliminate. With one person walking over a particular area and someone else down below watching for where the squeak is happening, you should be able to add a screw, a nail, or some shims to the right spot. If you have a typical crawl space with beams and posts, those squeaks could come from any place two pieces of wood meet. Or from where the wood meets supporting hardware. That's why someone walking over the area causing the squeaks can help the person below find exactly where the problem is.
And then there is the attachment of the subfloor to the joists. Perhaps the carpet needs to be pulled back and add some screws to get a firm attachment again. That will be difficult where you have tile or hardwood floors, then those screws need to come up from the bottom without causing problems to the finish floor. Or use a shim, jamb in best can do, add a little glue, and forget about it.
It's possible some of the fasteners have rusted, and are not holding firm.This message has been edited. Last edited by: Re-mdlr,
Thanks for your reply. We were also thinking that the fasteners/nails have rusted and have become loose. We just wanted to get an opinion to make sure it's nothing more serious than that because if it could be we would need to file an additional claim with the flood insurance. Thanks again.
