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.

These sill covers are the best thing yet! I have a kitten who continually jumps up into my windows and uses her claws to grab on. All of my windows were getting clawed up until I got these. They really work and the customer service is outstanding. I couldn't ask for anything more.

Absolutely awesome!!
These sill shields are PERFECT!! I purchased the clear ones for ALL my windows. Came back for more when I finished my addition. They are great protection from cats and dogs. The clear is great they blend right in.

Excellent product!
I have 3 large dogs and was hesitant to purchase this product. I am so glad I finally did! I purchased several months ago and it has withstood very playful dogs! I had a couple of questions and Gary was quick to respond! Highly recommend! Thank you Gary!

Great product!
I wish I'd known about these years ago. Two window sills in our home have been completely destroyed by our dog jumping up to look outside. I ordered a custom size, which fit perfectly, and they look great. The dog still jumps up to look out the window, but can't damage the sill. Worth every penny!

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.
