Mold on Window Casings: How to Remove and Prevent It

Have you checked your windows lately? If you notice any discoloration in their casings, that is likely mold at work. The presence of mold on windows is not something any homeowner should overlook. Not only is mold growth unsightly, it can also compromise the structural integrity of the entire window unit. Fortunately, there are a couple of easy ways to get rid of it, and even prevent it entirely. Renewal by Andersen® of New Jersey, the trusted installer of high-quality windows and sliding patio doors in the area, shares some of them here.

Mold on Window Casings
  • Clear your windows of mold. If your windows are still relatively new and structurally sound, you might get away with getting rid of the mold. The fact is that mold can become incredibly damaging in its advanced stages, so you won’t want to put off this task. First things first–wear safety goggles, gloves and a mask to protect yourself from mold spores. You should also cover the area underneath the windows to catch any falling mold or drips.

Before scrubbing the mold off the windows, make sure the room is well-ventilated. Try to open some of the doors and windows so that mold will escape instead of remaining trapped inside the room. Once that’s done, mix a mild cleaning solution consisting of warm water and bleach. Use a non-abrasive brush to clear away the mold on the casings, while making sure to dip frequently into the water-bleach mix. Wipe away the loosened mold with a clean cloth. Before closing the window, make sure the casings are clean and dry all the way.

  • Invest in higher quality windows. The simplest and most effective way to head off mold on the casings is to choose windows that are tougher and more efficient. In Renewal by Andersen® windows, for example, advanced Fibrex® composite is used for sashes and frames. The material is impervious to moisture damage, so you won’t have to worry about mold developing on your windows. The fact that our Fibrex® windows also keep an airtight seal when they’re closed ensures that mold won’t have a chance to build up around them.
