Why Is My Window Sill Warping?
Why Is My Window Sill Warping?
Window sills and wooden frames that are warped, cracked, or rotting is common in older homes. One of the reasons for this is that wood expands and contracts in response to changing weather conditions, causing the wood to warp over time.
Warping is most commonly seen in the Northern United States and Canada. The extreme cold in these regions can cause wood to expand more easily. Another reason for warping is that a window sill or frame can become wet when water leaks into the home through windows that are not properly sealed or when the water inside the home freezes and expands.
Water on wooden siding and shingles also makes it easier for wood to shrink and warp. In addition, the high humidity in these regions caused by frequent rains can accelerate the development of warping.
Trim and molding on the exterior of a home can warp from weather conditions and from moisture that collects in the walls of your home. Warping is also common in areas where there are large temperature fluctuations throughout the year, like tropical climates or areas near mountain ranges.
Warping of wooden window frames and sills can occur in older homes but is more common in new homes. Those with unheated attics have a greater risk of warping compared to those with central heating systems.
There are a variety of products and products that you can use to try to prevent or eliminate warping on your siding or window trim.
How Do You Fix A Warped Window Frame?
There are a few ways to fix a warped window frame, depending on the severity of the warp. For minor warping, you can try gently sanding the frame until it is level.
If the frame is more severely warped, you may need to remove the frame and reset it. To do this, you will need to remove the window sash and then the stops.
Then, you can unscrew the frame from the wall and reset it, making sure to level it before screwing it back in place.
Another solution is to fill the gaps around the warped windows with additional weatherstripping.
Another way is to use a clamp to hold the frame in place while you use a hammer to gently tap the frame back into shape.
