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.

Excellent Product
I purchased this product to protect the windowsill next to my front door and so far so good. Processing and Shipping was prompt. Received my order within less than 5 days. I had questions about product measurements and received a call back immediately after leaving voicemail. Product was so easy to install, instructions were included in case it was needed. So far the windowsill protector is holding up well and when my almost 50 lb pup stands on it I know feel relieved to know the windowsill is protected. Completely recommend this product.

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.
