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 SILLSHIELD@YAHOO.COM and please send a picture if possible.

Sturdy Material, Perfect Fit
Got a custom width to fit the sill behind my kitchen sink, fit just right and does a great job of protecting the sill from water damage!

Great product!
I recently purchased the Sill Shield guards for three of my new windows. I placed two sill protectors side by side as my window was too wide. Gary Castelle was a great guy to deal with and he responded right back to me re: a question on depth size. I received the order in just a couple of days. I would highly recommend this product and look forward to purchasing more as the new windows are installed.

Great Product
My dog was shredding our window sill. I measured the sill and ordered a custom fit product - it's amazing but I measured well and Sill Shield cut well, it fits perfectly. There was on place I needed to cut to fit a custom molding in the window, and a quick tap with a chisel worked perfectly.

My dogs were jumping on the window to look outside, and the wood was getting scratched. The Sill Shields provided a perfect, and attractive solution. I don't worry when I see them jumping up now. The clear Sill Shield is nearly invisible. Customer service was great when I decided to change from white to clear. This felt like something I had never imagined before - a personal connection while making an internet purchase! I am SO happy with these - a wonderful product and solution!
