Drywall repair guide
A small hole surrounded by firm, dry board may be a patch candidate. Crumbling edges, widespread softness or repeated joint failure can call for a larger repair. The choice should be based on material condition and the cause of the damage.
What to discuss before work starts
Photograph both the close-up damage and the entire wall. Mention whether the damage has grown, become wet or been repaired before.
Put the scope in writing
Confirm the affected surface, repair method, finish boundaries, room access and any separate work before scheduling. The condition of concealed material can change what is needed.
