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

Great product!
We love the sill shields! We put them in the master bath and bedroom where our kitties like to hang out. They fit perfectly and you can barely see them! I think they’ll last forever. There was a little hiccup with the order that Gary resolved immediately. If we ever need more, I’ll certainly order again.

My dog has decided he prefers the windowsill to wreak havoc on visiting ups and fedex drivers. He destroyed my dill with his nails. I found this product on line, spoke to the owner in customizing them to fit my sill. It works beautifully. They are strong and withstand his nails. I highly recommend these.

Excellent Product!
This is the second time I've purchased the Custom Width and Depth Sill Shields and I will definitely do so again! Each time they've been cut to the exact measurements I've provided and installed perfectly! This is an excellent product that works to protect my window sills from my dog's nails and you don't even notice them. Definitely recommend!
