Water Damage: A Tutorial To Replacing Damaged Drywall

Do you have water damage in your home? Sometimes the damage is obvious, due to flooding, storm damage, broken pipes, or other severe accidents. But if you have a slow leak somewhere, you may not even realize you have water damage until it is too late and cause a huge problem. Water damage can weaken the structure of your home, turn into mold, and make your home unsafe. Instead of paying thousands to have a professional fix the damage, you can do it yourself and save a lot of time and money. This tutorial shows you step by step how to find and repair water damage.

Things You Will Need:

  • Gloves

  • Dust mask

  • Utility knife

  • Putty knife

  • Drill

  • Safety glasses

  • Tape measure

  • Drywall

  • Joint compound

  • Joint tape

  • Wrecking bar

  • Paint (optional)

Step One

Locate the areas with the damage. Signs of discolored drywall or drips running down the wall are a good sign for water leaks. Your ceiling may show cracks or water stains. Be careful working with any walls that appear to have black mold on them. If the area is large enough, you need to have the black mold professionally removed. If the black mold is just a small spot, you can remove it taking the proper precautions. Sometimes you just need to remove the drywall and replace it with a new piece.

Step Two

Put on your safety glasses, work gloves, and a dust mask before you begin working. If the drywall is saturated enough, you can simply grab it and tear it off with your hands. Throw all pieces of old drywall into a garbage bag or dumpster. When the drywall isn't that soft, you need to use the wrecking bar to pry the piece of drywall off.

Step Three

Measure the height and width of the space that the new drywall piece will go in. Use the utility knife to cut the drywall to the proper size. Align the piece with the wall studs and screw it into place using your drill and drywall screws.

Step Four

Cover the seams of the drywall with joint tape. Take your joint compound and layer it over the tape using a putty knife. Let the joint compound dry completely before moving to the next step. Each brand of compound may have specific drying times, so check the product's label to get the estimated time.

Step Five

Use sandpaper to smooth the joint compound until it is smooth and flush with the drywall piece. At this point, you are finished unless you want to paint the wall. If so, move to Step Six.

Step Six

Apply primer over the entire drywall and allow it to dry. Take the paint of your choice and paint the drywall. Repeat the paint if necessary.


Always be careful when you are working with home repairs that may involve mold. Drywall dust can also be hazardous to your health, so don't ever work without your dust mask. Use a shop vacuum to remove dust and other small pieces of drywall from the area you are working in.
