Natural wood window frames have the power to insulate a home 400 times more than steel window frames and an incredible 1,800 times more than aluminum window frames. They’re also much better at limiting the noise that travels from outside your home than aluminum and vinyl window frames.

The downside? Wood window frames do require more regular maintenance than other types of window frames. But, with proper upkeep, these aesthetically pleasing window frames can last as long as 30 years and increase the value of your home.

How Does Climate Affect a Wood Window Frame?

Unlike aluminum and vinyl window frames, all wood was once a living material and is therefore susceptible to changes with the weather. Wood expands and contracts as temperatures and humidity fluctuate. The more your window frames change with the weather, the more maintenance they require.

If you live an area with harsh and direct sunlight, you will need to care for your wooden window frames more often to prevent the wood from drying out and cracking. Regularly oiling or waxing the wood will nourish it and help prevent problems from arising.

To clean up existing mold and mildew, mix a solution of four parts water and one part distilled white vinegar and apply it to the affected areas. Let the solution sit for a few minutes and then clean as instructed above.

If You Notice Cracks in the Wood

Cracks can show up out of nowhere as the wood expands and contracts with the change in seasons. If you do notice a crack forming, clean it out, and fill it with exterior wood filler. Once dry, sand the spot smooth and refinish the entire window frame to seal it.

If You Notice Loose or Cracked Caulking

The caulking on the edges of your window frames will need to be touched up every so often. Any signs of cracking, broken or loose caulking is your cue to trim the old caulking and re-seal with a heavy-duty exterior caulk.

If You Notice Foggy Glass

Windows that appear foggy or frosted are often a sign that the seal on your window is broken and moisture has found its way inside. Call a professional to determine whether a whole window replacement is necessary, or if it’s possible to replace just one pane and re-seal.

How to Refinish Wood Window Frames

Last, but certainly not least, every wood window frame should be refinished every two to three years to protect it from the elements proactively. You’ll find the exterior will require refinishing more often than the interior, but doing them both at the same time is a good practice.

Start by sanding the entire window frame with some fine-grit sandpaper. Wipe the dust away with a clean, dry cloth.
