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 SILLSHIELD@YAHOO.COM and please send a picture if possible.

Excellent Solution!
My dogs really go at the window sills when almost anyone walks by outside. I've gone through many tubes of wood filer and cans of white paint. This is a simple and very effective solution to those fur babies' craziness. If your dog is large/strong, I would recommend applying more adhesive/velcro along the Sill Shield to make sure it stays in place.

Exactly what I needed
My overzealous dogs have completely trashed my windowsills so I was eager to find a product that could protect them from scratches. This was the only vendor I could find that does custom sizes. They fit perfectly, were shipped quickly, and have worked wonderfully. My only regret is that they don't come in longer sizes or I would order them for every window sill in the house. I am very pleased with this product!

It works!
I bought these shields to protect our newly remodeled windows from our dog's attack against the mail carrier or any other moving object outside. We put them up, and they are fantastic! They actually work. I figured as soon as the dog hit the sill, the shields would fall down, but they didn't! I would definitely recommend this product for dog owners. Fast shipping, too.

Also great for plants!
I ordered this product to protect the window sills where I place plants. Even with saucers under the pots, the sill still needs protection. I didn't need to use the peel-and-stick Low Profile Dual Lock Coins. The plants keep the sill protectors in place.

Perfect solution!
We just finished a complete makeover on our house which included repairing our window sills from paw marks. We have two active beagles that love to go from window to window checking out all of the activity in our neighborhood. We ordered the window sill shields to put on all of the windows that are low enough for the dogs to put their paws on. They are working perfectly to allow the dogs to keep tabs on the neighbors without damaging the window sills. We are happy and the dogs are too. Our order arrived quickly and everything was correct. Thanks so much for having a great solution to prevent dog paw damage on our window sills.
