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

If you need special customization, such as a notch for a crank, email me at
and please send a picture if possible.

Love this product!
This is my 2nd order from Gary. I had them in my previous home. I contacted him for custom sizes and they fit perfectly, look great! I have the clear over natural wood and he sent clear fasteners to minimize seeing the attachment. It's barely noticeable. I put these on all my windows, they are so worth having to protect your sills, durable, and stay on even with pawing at them they are secure. Gary is wonderful to work with!

The sill covers work great! Dogs havent knocked them off once. My window sills were deeper than the protector but it still makes a huge difference. I wish that custom sizes could be deeper since I have another window sill that needs to be protected from cats but it is very deep. Great product!
from Loomis, CA.
Such a great idea! My dog had clawed all the way through the drywall on the sill. I had fixed the drywall and painted the house so I wanted some protection. This product did exactly that. The white actually gives a finished look to the window. Have had for about 3 weeks and the dog has not been able to claw it off! Very fast shipping and quality product.
from Ohio .
Product arrived quickly exactly how it was described. Our boxer mixed had done a pretty good job of scratching up the sill, which is now covered by the protector and now (because of the plastic I guess) she won't even jump up to look out the window, which is just fine!
from LIttleton CO,.
I am very pleased with the sill shield. It ordered easily, came quickly and works perfectly. My newly painted sills will stay un-scratched. Will order soon for my other window sills.
