Tips to Repair a Chipped or Cracked Bay Window Seat

It’s something that more than a few property owners have run into – the bay window seat, a wide sill for a larger bay window, can get chipped, cracked or otherwise damaged. This damage can come from excessive moisture that warps the boards, contact that chips off pieces or other kinds of problems like mildew or rapid temperature changes. Carpentry pros and others offer some neat tips for a do-it-yourself solution for your bay window seat. These address many of the common problems with excessive wear on a window seat, where damage may lead to less enjoyment of the home area and a compromised visual appeal for visitors.

1. Add Insulation


If your window seat cracked because of the cold air coming in against a heated environment, one way to keep it from happening again is to add insulation. Lots of property owners choose a blown insulation and simply seal up any inlets from the outside where cold air gets through.

2. Caulking


Along with insulation, some professionals recommend caulking to seal up air flow under or around a bay window seat.

3. Replace Materials


Many window seats are made with plywood. One solution when that wood becomes scored, chipped or cracked is to just replace the whole panel with new plywood. Double reinforcement can help deal with some potential problems of damage over time.

4. Address Moisture Problems


In some cases, excessive moisture can cause a window seat to warp and crack. Experts who visit homes with this issue often ask if the residents use a window sill or seat for things that can cause moisture buildup, such as watering plants. Changing the uses of a window seat, or putting down water catching layers, can alleviate these problems and keep all of the window trim in good shape.

5. Consider Flexible Woods


Some pros like to recommend a flexible wood such as birch for replacing damaged window seat installations. These kinds of wood may provide a more durable solution for future wear.

6. Look for Good Bonding Materials


If the window seat is tiled, adding more powerful bonding materials can make a difference. For example, some recommend using Keralastic/Kerabond, a system of flexible acrylics and premium mortar, for tiles and other types of coverings.

7. Change the Grade of Wood


The advice of some experienced carpenters is to use specific kinds of plywood for vulnerable installations. The use of “marine grade plywood” over cheaper forms has been a recommendation for chipped, cracked or otherwise destroyed window trim systems.

All of the above can help direct you to a solution for a damaged bay window seat. Looking at the installation, you can evaluate whether you may be able to cut out a portion and replace it, or whether the whole piece has to come off and be replaced. With the right fixes, your large and sunny bay window will be restored to its original glory.
