I have an 80 year old house and decided to renovate the bathroom. I ended up taking the floor right down to the 3/4" plank subfloor. One of the joists is higher and twisted therefore giving a bulge in the subfloor. From the highest point over to where the toilet is, it is out by an inch. If I raise that area the phlange of the toilet will be too low. What to do?
Cut the section of floor out from the joists on both sides of the high joist. Use a hand plan and plan down the high joist. ( I prefer a power planer. Box srore $35) You may need a chiselthe ends where the plan won't reach. Put a straight edge accross the joist to make sure there the same hight. Then put the wood you cut out back in or replace with new wood of the same thickness.
