Apex Window Werks restored stained casement window sashes in Wheaton, IL
What causes this?
This is a case of water damage and rot; an incorrectly angled sill or lack of a lip above the window could have caused rainwater to pool on the surface and rot away the frame.
Keeping stained casement windows in your home that have a natural wooden finish on the inside, like the one in the image above, looks great and adds a dimension of rustic beauty to any home- when new. The problem is that factors like moisture, temperature fluctuations, and sunshine will eventually leave your windows looking faded and deteriorated, especially on the lower sash and sill. This windows had the same fate and the lower sash needed to be replaced and repaired while the rest of the frame and trim simply needed to be sanded and re-coated (repainted on the outside). The stain and finish of the repaired window sashes had to be matched to ensure that it fitted in with the other windows in the home and the rest of the frame to restore the aesthetic quality these kinds of windows can add to any building.
Wooden casement windows (that is windows that are attached to a frame by one or more hinges on one side singular or paired within one frame) are great for natural air flow and ventilation, especially in warmer climates. Ensuring that your stained wooden windows are well maintained and scheduling regular checks for signs of weathering can save you a lot of time and money in the future.
