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.

Great idea and solution
Our dog was tearing up our window sills, and nothing seemed to make a difference, until I found these! Getting the custom sized pre cut from Gary was awesome. They fit perfectly, look nice, and protect our window sills so we can now keep our blinds open!

A real answer
We have two Westies that have done a number on our sills. We researched and found Sill Shield. We could not be happier. It looks great and has solved our issue. The custom size sill shield makes our sills look like new. Wish everything was this easy,

Life Saver!
We have 2 window jumping dogs and 2 grandchildren. These shield guards are window savers. Before finding them we had sanded and repainted the window sills several times in 4 years. You can hardly see them, they fit right into the existing sill and wipe clean with a damp cloth! Wish I had them 4 years ago. Thank you so much. Delivery was fast - couldn't ask for more!
