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.

Perfect Product!
This is a perfect product! I love that you can order custom dimensions, and now my window sills are protected from my cats claws! Gary even reached out to me to double check that I ordered the right color, which was very helpful!

This is a wonderful product to help protect my windowsills from my furpups. I wish I found this product sooner. It was easy to order, quick delivery and easy to install.

Looks great and works great
I have a 65 pound dog that put a hole in my window sill/stool while being a terrific guard dog. I patched up the hole and put this in place. It protects the wood, looks great, and it’s easy to clean. I highly recommend it!

Perfect Product
Having in our past house to twice refinish the wooden window sill immediately above the kitchen sink due to water spray, we found this product for our new house. EXACTLY what we wanted. Got it customer sized and it is working just as we wanted. Can not recommend it highly enough. There will be no need to ever refinish this window sill from water damage due to the “Sill Shield!”
