Custom sized windowsill protectors, available in clear or white. Choose your custom Sill Shield™ width (left to right along the length of the windowsill) and depth (front edge of the sill toward your window). All of my Sill Shields have a 1” drop in the front to wrap around the corner of the sill. You can order online, or by phone at 845-477-0737.

After years of constantly repainting my sills, they finally got to the point where the wood was so damaged, they had to be replaced. I wasn’t able to find a product to protect the new ones, so I created the first Sill Shield™. My sills are white, so I chose a white outdoor grade U.V. material to resist yellowing. For the clear Sill Shields, I chose a material called PETG, a tough, clear material best known for making blister packs and water bottles..

It worked so well that I decided to offer it to everyone in several standard sizes that fit many common window sills. Be sure to check out the Standard Sill Shields in case a stock size works for you:

The quality and durability of my original Sill Shield™ is superior to any alternative, and that’s why I’m the only one that offers my exclusive lifetime guarantee: As long as I’m alive, they’re guaranteed - when I’m gone, you’re on your own.

If you need special customization, such as a notch for a crank, email me at [email protected] and please send a picture if possible.

Good product, amazing support
We have a picture window looking out on a beautiful river, with about 200' of trees and grass between house and river. The dogs think this is "squirrel TV". Same channel everyday. This product was simple to install. Delivery to Canada only took a week, but the best part was the support from Gary. Highly recommend both company and product!
