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 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 and water bottles..

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.

Love my Sill Shield!
I absolutely love my new sill shields! It covers the sills perfectly and so far the dogs have not managed to dislodge them or even damage them. The stickies you provided were better than average so I am happy about that. Thank you!

Already tested
The shield works great and looks good. Very fast delivery. My 2 GSD's decided to jump in my new bay window the same day i installed my shield. Saved me big time...

Exactly what we needed
The Sill Shield is a quality product and is exactly what I needed to protect my window sills from my two Aussie's nails when they jump up on the window to kindly bark like heck at anything or anyone passing by. We just repainted and I was desperate to find something to protect the sills from their nails and these are perfect. This is a small company with excellent customer service. I made a mistake on my order and they promptly called me to question me about what they thought may be an error rather than just make it up and send it out and stick me with. I really appreciated their attention and excellent customer service. They arrived very quickly with good instructions and were very easy to install. No one even notices them on the sill and now I don't have to worry about the dogs jumping up and they don't get yelled at constantly to get down. You will be very happy with this product if you need your window sills protected.

Great Product and Great Service
Quick delivery , no damage. The sill protectors fit perfectly, stay in place, are very easy to clean and don't scratch - and they look great (blend with the trim). I have an Aussie that fiercely (!) guards our suburban neighborhood . Highly recommend!
