Custom width windowsill protectors, available in clear or white. Enter your custom Sill Shield™ width (left to right along the length of the windowsill - maximum 35 1/2 inches long), and choose a standard depth (front edge of the sill toward your window: 2.25", 3.25", or 5.25").

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 of my original Sill Shield™ is superior to any imitation product, 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 these for the exam room windows in my new veterinary hospital (the dogs were already jumping on the window sills and scratching the paint!)--they fit perfectly, attached nicely, and are working out very well. Highly recommended!

Satisfied, multi-dog household!
I love my sill shields! My sills were totally destroyed by my three permanent dogs and dozens of fosters dogs. They love to jump up and look out the front windows (of course). After repeatedly repairing the drywall and repainting, I was so thankful to find a better solution. Gary is very helpful, shipping was super fast, the sill shields fit perfectly and are a snap to install. I definitely recommend this product.

Great Product!
Our Maltipoo, Frank, loves looking out the windows to bark and enthusiastically scratch up the sills. He even clawed through layers of white duct tape. Gary Castelle and Sill Shields came to the rescue! Gary made sure he understood the dimensions of our sills, and made custom shields that were easy to install. They blend in nicely with the painted woodwork, and Frank not only cannot damage them, he just slides off, which has the added benefit of less barking!

Sill Shield to the rescue!
We recently remodeled our living room and put in big, beautiful new windows. Our dog was jumping up onto the windowsill and scratching the new white trim. I found Sill Shield online and thought it was worth a try to save my new sills. I ordered two custom shields. Within minutes, Gary emailed me with suggestions to ensure a great fit. He had them in the mail the next day. They have saved the day!
