Your home's bathrooms are equipped with interior plumbing pipes within the wall that are connected to fixtures that direct the water for your use and convenience. Unfortunately, when a leak occurs behind the walls of your bathroom, it can cause damage to your home's interior and require you to replace the materials to repair and restore your bathroom. Here are some tips and insight to help you repair and replace your basement bathroom wall after a moisture leak with water damage occurs.

Mold Clean-Up

After an interior water leak has saturated the materials in a basement wall, it is likely that the moisture has been present for long enough for mold and mildew to grow on the effected surfaces. Mold and mildew only needs moisture to remain on a surface for one to two days for it to begin growing and releasing additional mold spores to spread to other moist areas. A dark basement and a moisture leak presents the perfect opportunity for this type of damage.

It is important for you to remove and clean up mold from all damaged areas inside your walls and flooring. Leaving mold to grow uncontrolled can lead to health issues from the mold in you and your family members. Cut out affected drywall and insulation, and use a bleach and water mixture to wipe mold from non-porous surfaces and allow it to air dry. If the mold growth covers a large area within your home, you may consider hiring a professional mold clean-up company to handle the task.

Insulation Replacement

Once moldy insulation has been removed from an interior wall, you will need to replace it to restore the wall's ability to block out sound and heat transfer. If the wall is an exterior wall of your home, it is especially important to install an insulation with a high enough R-value to protect your interior temperature during summer and winter.

There are many types of home insulation you can hire for installation, or complete the work yourself. If the wall damage was not too large, you may replace the wall insulation with new roll batting insulation matching the surrounding walls, or use spray foam insulation, which expands to fit within the wall cavity and surround any existing plumbing and electrical work. It is important to make sure you replace the insulation to match surrounding insulation so you don't simply patch the damage with a sub-par repair. Talk to insulation contractors about your options and what they recommend to replace the missing insulation.

After you have the insulation replaced, you can install drywall over the damaged area to restore your wall.
