A poorly secured toilet will wobble due to loose toilet bolts. When this happens, it will eventually begin to leak, causing damage to your flooring. A corroded or poorly set flange could also be the cause. IF neither are the problem, it may be due to your subfloor. Use a wrench to tighten the nuts on the bolts, but don’t tighten too much as this could break your toilet. Check the floor around the flange. If it is spongy, repair this before putting your toilet back in place. The flange can be repaired with a repair ring or plate. For a stress-free repair, call Howell Services and our team will take care of your wobbling toilet.
