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.

Quality & Beauty in One Product!
I recently had the interior of my house painted and needed to protect my bright white window sills. These sill protectors are awesome!! Not only are they pretty to look at, they’re extremely functional. I no longer worry about my 2 dogs ruining my sills and a good paint job. The protectors stay in place and I LOVE them!! I highly recommend these protectors for anyone who takes pride in their home. THANKS for such a great product!!!

The Sill Shields look beautiful!
I recently bought Sill Shields for our newly finished window sills. The sills had previously been scratched up by our cat, which was why we needed to re-finished them. The Sill Shields look great and are keeping the sills like new..

Super great product
Even though my window sill is larger than the product maximum size, it still helps a great deal in protecting it and it makes it look even better. Service, delivery and product quality is 10 star! It's well worth it and I cannot say enough how I was more than happy with the look, and the efficacy of this shield. Thank you!
