Drywall Water Damage: Patching vs New Drywall Drywall Water Damage: Patching vs New Drywall


Drywall water damage can be a major problem, or it can be one that is simple to repair. It depend on the degree to which the drywall is damaged. If an an entire drywall sheet is damaged, that would probably involve replacing, rather than repairing, the entire sheet, whereas you could remove and fill in a small damaged part of a sheet.

Patching a Small Drywall Area

You can usually patch a small area of drywall that has been invaded by water. That is, for an area smaller than a silver dollar, that has had superficial damage near the outside surface, remove the damaged section, cover it with drywall tape, apply new drywall mud, then repaint it when the mud has dried and sanded.

Patching A Medium Size Area

If your damaged drywall area is half the size of the sheet, you can cut out the damaged section, remove nails or screws fastening the drywall to the studs, measure and cut a new piece of drywall to fit the piece you've removed, attach it to the wall studs, apply tape and mud, then sand and paint.

Replacing an Entire Sheet

To repair drywall where more than half of the sheet is water damaged, you'll be wise to replace the entire sheet by removing the sheet, along with any nails or screws, then attaching a new sheet as you would any new drywall sheet.
