If you’ve had wood or vinyl windows, you’ve probably had to deal with problems caused by warped windows at one time or another. Renewal by Andersen of Denver takes a look at the causes of warped windows, and how our replacement windows can be your long-term solution.

The Causes of Warped Windows
Long-term exposure to changes in humidity and temperature can cause warping in materials such as wood and vinyl, which are commonly used for building window frames and sashes. Wood, in particular, exhibits uneven expansion and contraction because of natural irregularities in fiber size. It also absorbs moisture, which causes swelling that doesn’t revert and instead results in further warping. This is why wood windows, as well as other wooden parts of the house’s exterior like siding and decking, have to be painted or treated with waterproofing. Vinyl windows can become permanently warped when exposed to high heat.
Fixing Warped Windows
Fixing a warped window involves planing parts of the window frame to return it to its former shape. However, this must be done with care, as planing it too much can result in gaps, resulting in leaks. Also, repairing warped frames and sashes is generally not an option if you have vinyl windows.
The best solution is taking the preventive route and investing in windows that are resistant to warping. Composites are the best choice because they expand and contract evenly. They’re also resistant to rot and other problems inherent to wood.
