Custom width windowsill protectors, available in clear or white. Enter your custom Sill Shield™ width (left to right along the length of the windowsill - maximum 35 1/2 inches long), and choose a standard depth (front edge of the sill toward your window: 2.25", 3.25", or 5.25").

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 imitation product, 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.

Perfect solution
This is a great product and a perfect solution to scratches on our widow sill from our dog jumping up to monitor sidewalk traffic in front of our house (She takes her job of "watchdog" seriously!). The sill shield is made of high quality material and fit perfectly. Website instructions were clear regarding measurements, and the ordering process was smooth and easy. Quick delivery. I highly recommend this product.

Best investment ever
I have always had to fix and repaint my window flats but these are the best protectors ever. Dogs can not scratch up you woodwork with these on. I have not even put stickies on and they stay in place I can even put plants and Knick knacks up without ruining the woodwork. Thank you Excellent product.

Simple Sill Solution!
Sill Shield was a simple yet sure solution for paint peeling on my window sills due to rain encroaching into the window and on the shield mainly during summer thunderstorms. I think Sill Shield is an excellent value and would recommend it to anyone looking for sill protection!
