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.

Window saver!!
So far this is working great to protect our window from claws and paws of our dog! Custom size worked well, clear cover is barely noticeable and stays in place.

You need this product! Trust me!
If you're reading this review, then you need something to protect your windowsills. The Sill Shield does exactly that, and is exactly as it appears on the site. I am so impressed with the quality. I had mine custom sized to make sure they hung over and covered the whole sill. Their thick plastic, totally transparent and just work, really, really well. My only regret is not finding this product earlier and ordering it right away. Oh yeah. I think it was like four days from time of ordering to receiving and this was for a custom size.
