Position the drywall section in the opening, and use a helper to hold the new drywall in place. Install fasteners through the drywall into the wall or ceiling framing. You can use drywall nails or drywall screws. Screws are better because they cause much less damage to the internal structure of the drywall sheet during installation. Install fasteners every 9 inches on the perimeter, and every 12 inches in the field. If necessary, use a piece of plywood or one-by lumber for a backing and fastening surface behind any drywall edges that don't fall over framing.
If the moisture damage has been neglected or gone unnoticed for long, you’re likely to find rot. Where possible, remove and replace soft, spongy studs and wall sheathing. Where removal is difficult, treat the affected areas with a wood preservative (available at home centers), after cleaning the wood and allowing it to dry. Then double up rotted members with pressure-treated wood.

Roofs. Keep roofs free of debris that can damage roofing and allow water to seep in. Trim tree branches to prevent them from rubbing and damaging the roof. Repair missing or damaged shingles. Properly seal any cracks around chimneys, skylights, and vents. Check metal flashing for holes, cracks, or other damage. Replace flashing or use silicone caulk to seal any openings.
You can easily spot the most visible type of mold, called mildew, which begins as tiny, usually black spots but often grows into larger colonies. It’s the black stuff you see in the grout lines in your shower, on damp walls, and outdoors on the surfaces of deck boards and painted siding, especially in damp and shady areas. A mildewed surface is often difficult to distinguish from a dirty one. To test for mildew, simply dab a few drops of household bleach on the blackened area. If it lightens after one to two minutes, you have mildew. If the area remains dark, you probably have dirt.
HEPA air scrubbers remove contaminants from the air.

The longer water damage sits untreated, the more likely it is that additional damage can occur. If it’s determined that drying equipment is needed, dehumidifiers will often be placed in the home to prevent against further damage like mold growth while the vendor is waiting for approval from the insurance company, if one is involved. Dehumidifiers can be present for one or multiple nights depending on factors such as the length of time the water has been present and the source of the leak. The contractor working on your home will be able to assess how long the dehumidifiers are needed.

Cut through the paper facing of the drywall sheet with a razor knife. Cut along the drawn lines. Break the drywall along the face cut, and fold the drywall slightly to make a crease in the paper backing of the drywall sheet. Cut through the crease in the backing paper with a razor knife from the backside of the drywall sheet, and remove the unwanted portion of drywall. To make cuts that are perpendicular to each other, use a keyhole saw for the shorter of the two cuts, and then fold and cut the drywall.
