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. If you have questions, you can call
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

My 94 lb lab mix loves to jump and look out the window. He was already leaving claw marks so I found this. My window was 46" but I got the 36" and centered it. Works great. Picture showing claw damage before it was installed, then one in use.

Great protection against dog paws
I had several windowsills that were chewed up from my German Shepherds putting their paws on them while protecting the house. After sanding and painting, I put these protectors down and they are keeping the sills looking new. (Pictures attached.) The transparency helps the cover blend in with the rest of the woodwork, although the glare can give away its presence. The 5-1/4 protectors are a perfect fit for all but one of my windows, which need one a little deeper -- but 5-1/4 seems to be OK. I needed custom widths, and they came cut within 1/16 inch of what I ordered, which was quite acceptable. Each cover comes with five pairs of Velcro-like discs, which are noticeable. Thus, I recommend putting two pairs on each end of the cover, as close to the ends as possible. Shipping is the same for one or several pieces, and it is pricy. Thus, try to order everything you need at once. I just found two more window I need to protect. :(

A Non-Pet Related Use of Sill Shield
Since I repainted the window above my sink and didn't want the paint job to be ruined or the wood moulding to be damaged I searched for some way to protect it. The installation easier than easy and due to its placement and the fact that it would not be a barrier for animals who would possible knock it off, it was not necessary to use the supplied "coins." The Sill Shield not only protects but the clear model allows the paint to show through. The only thing I would have liked would be more choices in length and width. I have a deep bay window where I keep plants and it would be great if a sill shield could be cut for use in that location as well. Thanks Gary for inventing and solving a simple need.

Saved My Window Sill!
I bought these to keep my dogs nails from digging into the sills. I LOVE THEM! Truly, they have saved my windows. They are sturdy, low profile and clear. They are hardly visible and yet provide all of the protection. Thank you Sill Shield.

We have an ottoman in front of our front window that our Great Danes like to lay on. They would drool when they got excited seeing dogs walk by, and the puppy chewed them a time or two. We had already planned on replacing the windows, but I knew I needed something to protect them. I googled window sill protection and found these. They work great. I didn’t even have to tack them down. I just laid them across the window sill. I can see drool on the protector, which means it’s not on my new window sills, and the puppy hasn’t tried to chew at all. I highly recommend these!
