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.

They work great!!
Ordered 2 white sill shields cut to custom width. Fast delivery. Our beagle/pit (36 lb) mix goes crazy when somebody walks a dog past house. These shields fit very well, perfectly protect the window sill & I was skeptical if the Velcro dots would keep them in place, but they do. White silicone caulk can be applied where shields meet window sill to really secure them in place, but I did not do this because it wasn't necessary. Great product!!

Totally worth the cost!
I wish I knew about this sooner! It's simple and does exactly what it says it will do! I have 3 small dogs who jump at the windows to see outside and some of my windowsills show plenty of wear because of that. I purchased a custom size for our window and it came quickly exactly the measurement I needed. i highly recommend this product and plan to purchase a few more.

Need met!
Perfect for my needs! My dog bites the windowsills. This prevents that and covered the damage he already inflicted on the wood! Thanks and I will be ordering more.
