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.

Great for dog owners!
We ordered sill shields for one window and we were so happy we ordered for the rest of the house and our door! Great solution to prevent our Great Danes from scratching the wood window sills and also keeps the drool from pooling on the wood as they sit in the window and watch outside.

The answer to my prayers!!!
I had been putting off painting my windowsills because I didn't know how I was going to keep them from getting destroyed by my dog who loves to go crazy barking at the window whenever another dog goes by our house. I searched and searched and finally came across the Sill Shield website and my prayers were answered. Gary, the owner, was so helpful during the ordering process and I was able to get my sill protectors custom made to the sizes that I needed. They look great and I am so happy with my purchase. I highly recommend these to any dog owner out there that wants to keep and protect their window sills from their crazy dog!!!!

Works perfectly
Gary made us custom sill shields - they perfectly fit my windowsill and prevent my puppy from chewing the edges. Because they are clear, they are not very noticeable. On top of that, Gary is extremely responsive to emails and professional. Even the custom sill shield was reasonably priced and definitely worth it.

Excellent product
Ordered custom size sill protectors and couldn't be happier. Dimensions were exact, received sills in three days, and had a chance to speak with Gary, as nice a fellow as you could ever want. By the way installation was fast, foolproof, and clean looking.j

Well made product!
Our kitty loves to sit in our kitchen window to watch the birds and we wanted to protect our window sill while letting him enjoy the view. We did a search on Amazon and found the Sill Shield but only in fixed sizes that wouldn't work for our kitchen window. Then we discovered your website and found we could order custom sized Sill Shields. We ordered the sizes we needed, the product arrived in record time and they fit our window perfectly! Our window sill is now purrfectly protected from kitty. Thanks for the wonderful product!
