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 fit!
This did the trick for protecting my window sill from my Australian Cattle Dog’s sharp nails. Sill Shield cut the protector to size and it fit perfectly!

Better than I expected!
The window sill protectors are better than I could have imagined. I recently had my living room painted and was dreading my 3 year old boxer to ruin the freshly painted sill, so did some research and found Gary. I have an old house (over 100 years old) so my windows are not standard size. But that didn’t matter - Gary was able to custom fit and had them shipped out to me quickly. I am so happy with this product and the price is right! I recommend it to any dog owner - it will save and protect your window sill.

great product
Actually got this sill shield because my kitchen window is right above the sink. Anytime someone used the faucet the sill would get wet. This works great to keep it dry and looks really nice.

If you have have 15 lbs of terror wrapped in white fur, as I do, you get Sill Shields or you buy paint, lots and lots of paint. My first Sill Shields were purchased when I lived in NY. When we moved and built our home in SC , Sill Shield was my 1st purchase. My window sills are protected. Out of the box and on your sills in seconds! Thank you Gary :)

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!
