Welcome to my Sill Shield window sill protector site, the only site for custom shields and standard shields in both clear and white. 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
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.
It worked so well that I decided to offer it to everyone in a few standard sizes. They were an instant success but I began to get requests for more standard sizes, so now there are 9 and from those people with colored or natural wood, requests for a clear version. For the clear, I chose a material called PETG, a tough, clear material best known for making blister packs.
I asked a few select pet product companies to help distribute the standard sizes of my product and of course, there have been a few copycats but none of those approach the quality of my original Sill Shield. That’s why I’m the only one to offer my exclusive lifetime guarantee: As long as I’m alive, they’re guaranteed - When I’m gone you’re on your own.
Please see the size chart below to check out the standard sizes. If none of the standard sizes work for you, then check out my

Just what we needed
My dogs were doing significant damage to the window sills on the windows overlooking the driveway, since they have to try to get at anyone who comes to the house. No more worries with these sill guards. So glad I found them.

Solved the problem!
Our dog’s nails had destroyed the window sill in his never ending quest to watch for squirrels. After fixing our sills and installing the Sill Shields, the problem has been solved. We noticed our dog doesn’t even go up on the windows as often.

Love this product. My dogs actually avoid touching it at the moment ha but it's a life saver for my windows. I originally ordered wrong color and it was super easy to switch out! Already ordered more!

Exactly what we needed to protect our brand new window sills from our animals. Will be ordering a few more for the rest of our windows. Thanks for putting out a great product!
