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.

Awesome Product
I love this product. Wish I had discovered it sooner as my dog has damaged 2 window sills. The ordering process was easy. Just measured my sills and placed a custom order. Items were shipped quickly! Highly recommend this company and product!

Custom Sill Shield
Ordered a custom sill shield for a window with white trim that my two cats love to climb onto. After sanding and repainting, we installed the shield and it fit perfectly. The cats didn't notice the difference and still use the window, but now we don't have to worry about them scratching the paint. Will definitely by ordering for other windows!

Excellent product
This is the second purchase with this company and it was great service, fast delivery, and reasonable prices. I just recently told my friends and family about this site to help them save their sills from their fur babies. 5 stars and higher. Thanx Gary!!!

Quality product and service
I have large custom casement windows with painted wood frames and the sills were being destroyed by my dogs. I was looking for something that would fit on top of the existing sill and that I could paint to match the white wood frame. I placed an order for one window as a test. It arrived just a few days after ordering. The custom depth fit perfect and I used a table saw to trim the lip to the correct size. I roughed up the glossy white plastic finish with some light sandpaper so the paint would adhere and not scratch off. They look great. I will be placing an order for my other windows shortly.
