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", 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.

Gary was great to work with and he confirmed custom sizing before completing. I can't say enough good things about this product. It's a tough material that has finally protected my window sills from my huskies' curiosity and sharp nails.

Just what I was looking for!
Between the cats and the dogs, the window sills were really marked up. Because we were getting new windows, I ordered these shields to prevent the scratches from damaging the new windows. They fit perfectly and the stickers are helpful in keeping them in place, thanks!

Fit my needs perfectly
Someone recommended getting a sill shield. When I ordered the shield from Gary he told me it would arrive in five days. It did. The shield fit my needs perfectly. Should have gotten one years ago.

Awesome product, answer to our prayers as our dog w as s tearing up our lower sills every few months requiring total refinishing. Now it protects them, inconspicuous, and easiest application ever. Cut to size perfectly and we had it within free days. Owner even caught that I had ordered on of the items in white instead of cleat, thanks!!

Great product , excellent value
Easy to place order and it arrived very fast. Product exactly as shown . Love the lifetime warranty . I emailed to ask a question prior to purchasing and received prompt response. I have dogs that love to sit at the windows and patrol our house. They mean well but when anyone comes to the door or too close to the property they have always jumped on the sills and inadvertently scratched up the wooden sills. Thank you, thank you thank you!
