Step 1: Assess the Damage

Before you start any repairs, you need to assess the extent of the damage. If the drywall is still wet, allow it to dry completely before you start any repairs. Running a fan on the area will dry in fast. Once it’s dry, look for any signs of warping, sagging or soft spots. If the damage is extensive, you may need to replace the entire section of drywall, which is best to do. However, if the damage is minimal, you may be able to repair it with joint compound or fast setting spackle.

Step 2: Remove Any Damaged Drywall

If you need to replace a section of drywall, use a utility knife or a drywall knife (best tool for the job) to cut out the damaged area. Make sure the cut is straight and even, as you’ll be using it as a template to cut the replacement piece. Remove any loose drywall paper around the edges of the cut, as this can prevent the replacement piece from fitting properly. 

If the plumber opened up the wall or ceiling to fix the leaking pipe. Then you can skip this part of the repair process.

Step 3: Cut a Replacement Piece

Using the cut-out section as a template, cut a replacement piece of drywall to the same size and shape. Make sure it fits snugly into the hole, and use screws or nails to secure it in place.

It is best to replace the drywall with moisture resistant sheetrock. Since the area has pipes or plumbing around it, a wet room type drywall is best. Even if the repair is done in a living room or bedroom.

Moisture resistant drywall comes in green, blue or purple according to the manufacture. Look at the label to make sure. Don’t go by color alone.

Step 4: Apply Joint Compound

If you’re repairing a small section of drywall, you can skip steps 2 and 3 and apply joint compound directly to the damaged area. Use a putty knife to apply a thin layer of joint compound over the damaged area, making sure to feather the edges to blend it in with the surrounding wall.

Allow the joint compound to dry completely before sanding it down and applying a second coat.

Step 5: Sand, Prime and Paint

Once the joint compound is dry and you’re happy with the finish, sand it down to a smooth surface. Wipe away any dust with a clean cloth before applying primer. Then paint to match the surrounding wall.

Kilz is a good primer and stain blocker to apply before you paint.
