What Can You Do About Mildew On Wooden Window Frames?

Mildew can ruin your wooden window frames by staining them black and making them look unclean. Follow these tips to eliminate the mildew and keep them looking beautiful.

What causes mildew to grow on window frames?

Mildew can grow just about anywhere, but it's much more likely to form on window frames that are cool, moist and aren't exposed to a lot of direct sunlight. Condensation on the inside of the window, especially on windows that face north, can create the right conditions for mildew growth.

How can you get rid of mildew growing on a wooden window frame?

Mix 1 cup bleach with 1 gallon of water in a bucket. Pour the solution into a spray bottle, then put on protective eye wear and gloves. Spray down the parts of the window frame covered with mildew. Leave the solution to sit on the mildew for a few minutes to kill the spores and soften the growth.

After waiting a little while, scrub away the mildew from the window frame using a plastic scrub brush. Scrub with the grain of the wood to avoid damaging the paint and to also ensure that the bristles of the brush fit into the grooves of the window frame. When you're finished, use a dry cloth to wipe away the remaining liquid. If some mildew remains, repeat the process until the mildew has been fully removed.

How can you prevent mildew from coming back once it's been eliminated?

Mildew will grow back unless the conditions around the window frame are changed. You can prevent the mildew from returning by painting the wood with an anti-fungal paint. You can also run a dehumidifier to reduce the moisture in the room and make it more difficult for the mildew to return. If the windows are covered by heavy drapes, leave the drapes open for several hours each day to increase air flow and give the windows a chance to dry.

If the window is regularly covered in condensation, reducing the condensation on and around the window is key. Condensation is a sign that your house windows are poorly insulated. If your windows have a condensation problem, have them inspected by a professional windows contractor, like R & K Windows. He or she can tell you what can be done to stop the formation of condensation on the inside of your windows.

Without changing or improving the efficiency of your windows, you'll need to monitor the condition of the window frames and remove mildew on a regular basis.
