Custom depth windowsill protectors, available in clear or white. Enter your custom Sill Shield™ depth (front edge of the sill toward your window - maximum 5 1/4"), and choose a standard width (left to right along the length of the windowsill: 23.5", 29.5", or 35.5").

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 other windowsill protector, 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 Solution!
I wish I had found Sillshield sooner to protect a window sill where our dog likes to put her front paws and watch the world go by. My custom order was a perfect fit, shipped quickly, and well-packaged. Seller provides an excellent product and service.

Fantastic product. Bought these a year ago and just had all of my windows replaced and immediately ordered new ones to fit the new sills. Highly recommend! I will be ordering more.
