Drywall repair guide
The repair method depends on the opening size and whether the surrounding board is sound. A fitted patch may need support behind it, followed by taped joints and feathered finishing.
What to discuss before work starts
Address the impact source too. A suitable door stop can help prevent the same damage after the wall is repaired.
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.
