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 Product--Great Company
The sill shields are exactly what we needed. All of our windowsill are deep and made of drywall, and none are the same size. We ordered a custom Sill Shield for each window. Our order arrived in about a week. All of the Shields were made to our specifications. We highly recommend using this company and their product.

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!
