Welcome to my Sill Shield window sill protector site, the only site for custom shields and standard shields in both clear and white. 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
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.
It worked so well that I decided to offer it to everyone in a few standard sizes. They were an instant success but I began to get requests for more standard sizes, so now there are 9 and from those people with colored or natural wood, requests for a clear version. For the clear, I chose a material called PETG, a tough, clear material best known for making blister packs.
I asked a few select pet product companies to help distribute the standard sizes of my product and of course, there have been a few copycats but none of those approach the quality of my original Sill Shield. That’s why I’m the only one to offer my exclusive lifetime guarantee: As long as I’m alive, they’re guaranteed - When I’m gone you’re on your own.
Please see the size chart below to check out the standard sizes. If none of the standard sizes work for you, then check out my

This product is amazing! I wish I would have found it sooner! It blends in well, I purchased the clear because I have stained wood sills. It will save me so much work as I’ve had to sand and poly my sills several times to keep them looking good. Finally, it was so easy to install! If you have a dog that jumps on your windowsills you NEED to get this product!
Let me begin by saying, I don't write reviews. However, this product far exceeded my expectations. At first, I thought I would save myself a few bucks by buying my own vinyl corner trim and cutting it into place but I'm glad I didn't. That's not what this is. This is a smooth, heavy-duty plastic that fits perfectly over your window ledge. I didn't have to cut, I didn't have to measure, they just went into place right out of the box. They arrived faster than I had expected (in a matter of days) and they took about 10 minutes to install in four windows. They look great, you can hardly tell they're there. But best of all, they work. One dog hates the way they feel and has stopped jumping up on the windows and the other two, when they do jump up to look out, cause absolutely no damage. I couldn't be happier. This was well worth the money.
Worked great immediately. Although slightly longer than I expected, after I cut it and mounted it with the included 3M velco coin stickers, they were perfect. WIthin 10 minutes of install, my 50 pound dog went to town on the product and it withstood without issue!

These are great. My dog has separation anxiety and is constantly jumping on the window sills when we leave the house. I saw them getting scratched up - given that I’m in an investment home and plan to sell in a few years, I want to keep everything in good shape. The sill shields are affordable, easy to use, and work. I called with questions before ordering and Gary was very helpful and honest. Great communication, and product arrived quickly.

Save the window sills!
I am so glad we bought these. We recently remodeled our home and the window sills were all banged up because of three dogs who like to say hi to the mail carriers. :). After we fixed them we wanted to protect them and I came across Sill Shield in an internet search. We bought some to try out and they were so good we bought another set for our family room! You might see something similar at other stores or Amazon, but I highly recommend these. They're thick and durable! A great decision to buy these. Thanks!
