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.

Just what I was looking for and more
I am so thankful to have found the window sill protectors. We have two German Shep. dogs who love to protect our home but will put their paws on our wood sills when anyone approaches our home. The sills are fabulous and are truly not that noticeable. Thank you for such a fabulous product.

Would buy again
Great customer service, Gary went above and beyond throughout the whole process, and even sent me a sample to see if it would work on my windowsill. Would highly recommend this product. Fit underneath my window cranks and works perfect. White color blends in well with my white window trim also.

Amazing fix
I have 4 large dogs who LOVE to look out the windows and 'znnounce" passers-by. Their claws have done an awful number on the window sills (which i tried to protect with custom cut acrylic but that didn't protect the edges). Gary's product completely cover the top and edge of the sills and they fit perfectly!
