Custom depth windowsill protectors, available in clear or white. Enter your custom Sill Shield™ depth (front edge of the sill toward your window - maximum 5 1/4"), and choose a standard width (left to right along the length of the windowsill: 23.5", 29.5", or 35.5").

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 other windowsill protector, 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.

Fantastic product. Bought these a year ago and just had all of my windows replaced and immediately ordered new ones to fit the new sills. Highly recommend! I will be ordering more.

Works perfectly!
I had purchased several window shields that I needed to proctect the window sills from my dog damaging them. I had also also contacted Gary about a custom order for a door protector where my dog scratches the molding around the inside of the door molding where my dog had scratched . He made a sill shield for me but made the lip shorter so it fits PERFECTLY over the molding around the door! I am a very happy & satisfied customer!!

Perfect and easy solution
We have a lower large window in our front room. Our dog spends most of her time waiting patiently for someone to walk by so she can massacre the wood sill. No matter how many times I’d patch and paint, it would always end up a scratched and chipped mess. Enter SillSheild. I needed a custom depth and order 3 pieces to best fit my oversized sill. They came so quick and installed so easy. Couldn’t be happier with the product. It’s just nice to get something that works in such an easy and fast transaction. Now my dog can scratch and bark to her hearts desire with no damage at all.
