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 white outdoor grade vinyl, the same durable, U.V. resistant material used in vinyl siding. 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 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.

Works perfectly!
We ordered custom window sill protectors for an abnormally shaped window that our 55 lb dog LOVES to look out and scratch. I looked everywhere for something that would protect the sill, look nice and hold up to our dog when the UPS guy comes! ;) These were perfect! Gary worked with me so customize it exactly how we needed it and they look great- you can hardly notice them and are holding up well to our dogs abuse! The only suggestion/request I would have would be to include more of the sticky/velcrow things to secure the covers- we added some command strips to ours as our dog knocked them off a few times. Otherwise absolutely great product!

works great
I was able to custom order sill covers for my mahogany-trimmed windows. They fit really well and are holding up great with 5 dogs that love to look outside! Wonderful product, easy to install.
