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. If you have questions, you can call 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.

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 custom size Sill Shield page.

Pet Guardian

The clear plastic sill cover was shipped quickly and works great. Puppy was already jumping on the sill, so the shield is saving the wood and paint. The plastic attaches with small Velcro circles, which are not very noticeable. Thanks!

Great Product

This product is made solid and does what it says it will do. Protect your window sills. Gary is great to work with also. These are worth every penny.

Perfect!

These are exactly what I needed to prevent my puppy from chewing my windowsills. Great fit, easy to install, and they look nice too.

Does what it says!

Works like a charm. Better yet, Gary was helpful and responsive. Happy to have saved my window sills and bought from Gary.

Owner Tested, Pet Approved. Both Very Pleased

I recently moved into a larger apartment in a 1962 building. There are layers of paint over worn wood from decades of nobody replacing the sills. I had 3 rooms of long sills I wanted to refresh, protect, and also make easier to wipe down after my cat lays on the window sill all day in the sun. Gary’s WHITE SILLS, which I laid down directly, ignoring the supplied disc pads for now, really did the trick. (Nothing to it! Just remove from box and lay over sill.) I have 5 pieces in front of 4-windows in the living room, and 2 pieces in front of each bedroom’s 2-windows. Even in the late afternoon, the shine glistens from feet away. So happy I chose this sill solution. Gary is so easy to work with and the box arrived overnight each time. We couldn’t be happier with this very inexpensive sill solution.
