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.

Good product, amazing support
We have a picture window looking out on a beautiful river, with about 200' of trees and grass between house and river. The dogs think this is "squirrel TV". Same channel everyday. This product was simple to install. Delivery to Canada only took a week, but the best part was the support from Gary. Highly recommend both company and product!

We recently replaced all the windows in our living room, which consist of an oversized window seat, where our dogs spend a lot of time, and windows that are about seven feet tall on either side of our fireplace and are only about 6” from the floor, that the dogs look out all the time. We love our dogs, and they love looking out the windows, and we didn’t want to affect the quality of their lives by taking this away from them. Not wanting the sills of the new windows to suffer the terrible fate of the old windows, I started a search for a solution. There were a few options I found that didn’t impress me at all, and then I found the Sill Shields site. After fully studying all the information available, watching Gary’s video (a few times), and reading the reviews, I contacted Gary with some questions. He responded right away, and I decided these were worth a try. My first order was for 2 standard-size Sill Shields and 2 custom-size for the window seat. They arrived promptly and fit perfectly. Then I ordered 2 more custom-size for the long windows on the sides of the fireplace; these also arrived promptly and were perfect. Then I ordered 2 more custom-size to cover some trim, and Gary had those to me in just a couple of days. All I ordered are clear and are only noticeable if you’re right up close to the windows and actually looking for them, so basically not noticeable at all, and they totally cover and protect the sills (and trim). I can’t stress enough how pleased I am to have found these, as they have already proven their value. Add to this the fact that you deal directly with Gary, who was very prompt in all his personal responses, and all orders arrived very quickly. BOTTOM LINE: IF YOU’RE LOOKING FOR A SOLUTION TO PROTECT YOUR WINDOW SILLS, LOOK NO FURTHER AND ORDER THESE ASAP!!!

Very Happy with this product! Did exactly what we needed and expected.
We have two Boxers who love to look out the windows. These 8 Sill Shields were installed in under ten minutes on all our windows and now our dogs will never scratch our window sills again. Thank you Sill Shield!
