How To Prevent Mold Growth In Your Walls After Water Damage

Posted on: 15 May 2017

When water damage occurs from a water leak or interior flooding incident, it can leave many surfaces and items inside your home wet and prone to mold growth. Mold can begin to grow in as soon as 24 hours under the right conditions, so time is of the essence in drying out your home after moisture problems occur. Here are some tips to help you clean up to prevent mold growth within the walls of your home.

Remove Water

First, you will need to remove any standing water from inside your home to start the drying-out of your home's interior. Use a shop vacuum to remove any excess water and direct fans on the wet flooring to dry it out as soon as possible. It is also helpful to open windows in your home to circulate air or turning on your home's heating system to help dry out the surfaces. 

Dry Out Baseboards

Remove any baseboards from around the base of the walls where the water damage has occurred. Use a pry bar to carefully remove the nails attaching the baseboards from their position. Set them outside to dry in the sun or in a garage if the weather is wet.

Most baseboards can be salvaged when they have been water damaged. If they have begun to show signs of mold growth, wipe them down with a bleach and water solution of one part bleach to ten parts water. Use a rag or sponge to wipe the mold from the baseboards, then allow the solution to air dry on its surface.

Repair Your Walls

Drywall that has been moisture damaged should be removed and replaced with new drywall, because it is easy for mold to grow behind the wall materials and out of sight even after the drywall has dried out. Also, drywall can become softened and lose its integrity in the presence of water. So, cut out the sections of wet drywall with a utility knife and replace the missing areas with new drywall.

Before sealing up the wall with new drywall, you may need to remove any roll batting insulation within the wall that has become water damaged, as it can also harbor mold growth. Spray-in foam insulations are usually moisture repellent and can be left in place. Direct box fans onto the wall studs that are wet from the water damage, making sure they have dried out before putting your wall back together.

Use these tips to help you keep your home's walls free of mold growth from moisture damage. If mold is already growing or your have additional concerns, contact a mold remediation service.
