Custom width windowsill protectors, available in clear or white. Enter your custom Sill Shield™ width (left to right along the length of the windowsill - maximum 35 1/2 inches long), and choose a standard depth (front edge of the sill toward your window: 2.25", 3.25", or 5.25").

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.

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 of my original Sill Shield™ is superior to any imitation product, 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.

These look great and are holding strong a month in to use. We ordered three in white with a custom width for the windows in our dining room where our wheaten had scratched the paint off the sills and exposed the wood. Very happy with the white -- blends right into the paint. The order arrived quickly and seamlessly. Great product and service :)

Phenomenal product
Where have these been?? I have 2-3 dogs at all times and my window sills are always terrible looking because my larger dogs hate UPS/FED EX trucks and go crazy at the window. I sanded and painted them and put the SIll Shields on and absolutely love them!! Mine were custom fitted and look great!!
