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", 4.25'' 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.

Great guards!
Our cats were shredding the drywall sills in our apartment. These guards are perfect and look great. We had irregular shaped sills, and Gary was able to make custom sizes. He was very responsive and professional and shipped almost next day. Highly recommended if you have fur babies who like to look out the window!

Great Product
This product does a great job of protecting our new casement windows from the dog perching on the base of our five new living room windows every time a squirrel runs across the back yard! Easy ordering process and fantastic customer service service!

Super Product
Had a custom order for 2 large windows in my dining room. Our 2 dogs are constantly on these window sills watching the wildlife in the forest bordering our back yard. My order came very promptly in just a few days and was extremely easy to install. I ordered the solid white, and unless you tell someone about them, they don't even notice anything's different. My wife is very particular, and she is very pleased with this product. Thanks Gary for your excellent service and great product!
