Over time I have noticed what appears to be my bathroom tiles moving out of place, as if the floor is slowing caving in. I do have an older house and there has been water leakage from the bathtub into the kitchen that has since been fixed. My question is what kind of professional do I call to take some look at my bathroom floor/kitchen ceiling for repair?
Call several home repair contractors and get estimates. The estimate should be free. Ask before the contractor before he comes if he/she gives free estimates. You should be able to find home repair contractors in the phone book or your local news paper.
well its called a realtor.. you wont want to hear what a contractor has to say.. depending on the damage and the possibility of mold you could be 10K deep before a faucet turns on.. what you described is major damage to the point joist need to be replaced you may luck out and new subfloor installed but to get to that nearly the entire bathroom needs to be ripped out. you as a human sees a bit of concave but what you dont see is the decades of damage so imagine ripping EVERYTHING out of your bathroom and rebuilding it.. again if you have describeds this correct so mutch water has caused the beams to bend.. you might be able to save the floor joist but you may need to remove the entire bathrooms floor is possible it only gets worse under the tub..
You will most likely need to pull up the old tile, float the floor level with thinset, and then lay down 3/8 inch concrete tile backer board. This will fix it and hold up for another 75 years. Without the tile backer, water will continue to get through the grout cracks and warp the original wood floor. You can then lay Linoleum or new tile on the floor and calk it up good. They sell the toilet flange adapter rings to make up for the new floor backer board. Hopefully you have a claw foot tub, then it's easy to strip the floor and re-due it. Add; if the house is old and built out of old growth Fir, the black mold won't grow on it so it's usually structurally fine. The issue you have is with the floor boards, there will always be enough left on the old Fir joists to sister up some new joist runners with lag bolts if there is a rotten area to level up.
