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 [email protected] and please send a picture if possible.

Awesome! Everything perfect!

Great communication, great price, perfectly cut, shipped quickly. We are so happy we found him and love our products! Now our dogs won’t keep ruining our window sills. Highly recommend! We got the clear and love them!

Peace At Last

I almost never review goods or services, but I was so impressed with Gary’s work that I couldn’t pass up the opportunity to write this review. Gary is incredibly responsive and fast. He patiently worked with me to develop customized protectors not only for my sills but also for vertical portions of my sills throughout the entire first floor of my house. The protectors are high quality and fit perfectly. Gary is a true craftsman. I can finally relax when my dog runs to the windows. No more destruction.

Excellent product, Great Service

Having seen what our dogs toenails can do to the window sills in our previous house, we wanted to protect them in our new house, before the dogs got there! With a little back and forth emailing, Gary did a great job in accommodating the narrow depth of our sills and provided us with the perfect custom fitting protectors. And we got them in less than a week! That meant I had them installed before the dogs arrived. Thanks so much Gary!

Sill Shield

This was just what we needed to protect our windowsills from the dog's nails. It was easy to install, it looks nice, and shipped very quickly. We will definitely be ordering more.

Homeowner

Our dogs love to stand on a window seat and look at the window. Mostly to bark at everyone walking across the street. The window sill was pretty scratched up. I researched options for this and am glad I selected Sill Shield. The ability to customize the length is huge. We needed three pieces to perfectly cover the sill. While it might have worked with buying stock sizes, I really wanted a professional finished look. It might be a simple thing, but it matters. I also want to mention the customer support i received from the company owner (also named Gary). I emailed him for advice on how to divide up the window section and the proper depth. He responded that same day (Saturday night). On Sunday, he emailed me with the shipping information. Later that week, they were installed. I would recommend this product to anyone that has this problem.
