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.

I purchased this product to "test" it on one window a year or so ago. Loved it so much that I just purchased 7, custom sized, Sill Shields for our new home. the order was delivered so quickly that I could hardly believe it! Especially for custom work! Awesome product! Fits perfect! Thank you so much!

Great product, fast service!
I desperately needed something to protect the window sills in my new house from my overexcited dog. These were the best option on the market, and they came FAST (even the custom sizes). Thrilled to be able to support a small business doing great work!

Great product!
We just moved and we have an anxious older dog and a puppy. We were very concerned that our custom built newly constructed home would sustain some damage in adjustment. We love this product. It is sturdy, well-priced and the service is exceptional.

Exactly what I was looking for
My dog gets excited when she sees animals running around in our backyard and ultimately totally scratched up the window sill pretty badly. When I had it patched and repainted, I knew I needed something to protect the surface and still allow my dog to have fun. This product does just that. It is elegant looking and very very easy to install. It took a total of two minutes. It matches very well with the window sill paint and fits perfectly. I also appreciate Gary's quick response to my questions before purchase. I definitely recommend this product. Thank you so much!

Just what I was looking for and more
I am so thankful to have found the window sill protectors. We have two German Shep. dogs who love to protect our home but will put their paws on our wood sills when anyone approaches our home. The sills are fabulous and are truly not that noticeable. Thank you for such a fabulous product.
