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 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 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.

Great Product and Customer Service!
Gary was very prompt and helpful in guiding me to the right custom order for my window sill protectors. I emailed him twice to make sure I was ordering correctly and he responded quickly and was very friendly and helpful. The custom protectors look great and fit perfectly!

Highly recommend if you have dogs
We have 3 big dogs that like to look out the window and unfortunately also like to jump on the sills when squirrels go by...we were replacing the window and did not want the new sills to be destroyed so did some research and found this company. I can't say enough good things ! First of all the service was outstanding - we needed custom sill covers and Gary was fantastic (and patient!). We sent him the measurements along with some pictures and he was able to fit them perfectly. They came with adhesive tabs - we put one on and didn't really like the look so removed them - they were so easy to remove and didn't damage the wood - they fit so well we don't need any adhesives so have just left them off. We went with the clear and while you can see them they don't take away from the window - they look much better than having a gate in front of the window, they are easy to clean and most importantly- they are saving my window sills! I have already recommended these to family members and will be placing an order for some for another room soon - you can't beat the price or the durability!

I love this. I wish I would've had one years ago.
I have a nosey dog who rushes to the window. We just installed a new one and this sill shield does the job.

Great product!
We had just gotten our whole house painted and within a week our dog had scratched off much of the paint on our oversized windowsill. After a bit of searching, I found sill shield. Gary was great to work with — super responsive and had our custom order out to us within days. Installation was simple and so far so good. Dog’s nails can’t scratch our paint off anymore! We got the clear, and it is hardly noticeable if you are standing at a distance away from the window.
