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 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.

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 custom size Sill Shield page.

You will not be disappointed

You can not ask for more from this company. The quality of this product is much better than the competitors. Ordering is easy and they even offer custom sizes. Product arrives quickly and is securely packed. Pricing is also lower than competitors. My only mistake is that I did not find them and order years ago.

I've been thrilled with every item I've purchased from Gary, but this one is exceptional. I just wish I had bought it sooner before all the damage was done! The product fits our scratched up windowsills perfectly, and it looks lovely to boot. Can't recommend highly enough.

Mr.

Gary provides an excellent and durable product at very reasonable prices. The sill shields can be custom cut to provide a tight and confluent fit on the sills and the shipping is lightening fast as well. I have used Sill Shields on several occasions and I highly recommend them for this service.

The clear plastic sill cover was shipped quickly and works great. Puppy was already jumping on the sill, so the shield is saving the wood and paint. The plastic attaches with small Velcro circles, which are not very noticeable. Thanks!
