I have a 5 year old home that has settled a bit and three doors are now
not catching on the latch. I realize that I can take the catch plate
off and chisel out some of the wood and lower the plate but am worried
about what to fill in the old holes with and if that will be strong
enough.

Any advice on how to fix this would be appreciated. I have tried to
shim the doors up at the hinge plates but it did not work (someone had
suggested that).

Thanks in advance for all of your help
Richard
