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.

I can't tell you how pleased I am with my custom sill shield! It fits on my windowsill absolutely perfectly. It is thick, sturdy, and covers the windowsill so well. We have two large dogs who like to jump up and look out of our front window, and they were tearing up the windowsill pretty badly in our new home. Our Sill Shield protects the windowsills so well, I will seriously never have to worry about them again! AND you're supporting a small business, and not the "other guys" on that big website (you know the one).

Great product and service!
I bought this product to protect and prevent rot on the window sill behind our kitchen faucet, which was constantly getting splashed during dish washing. I had a few questions before ordering and customer service was excellent in helping me identify the correct custom sill shield to order. Delivery was fast, application was easy, and I'm very happy with the results.

It is perfect!
The entry of my house is the only room with a window looking out onto the street. This is the only window my dog has any interest in looking out. It also gets direct sunlight so my dog loves spending time in there. The SillShield is the solution I have been looking for to protect my windowsill from getting damaged by her claws! I absolutely love it and will recommend it to my friends. I am going to get a 2nd one--my windowsill is long and I wanted to make sure a 2nd would fit before ordering.
