Custom width windowsill protectors, available in clear or white. Enter your custom Sill Shield™ width (left to right along the length of the windowsill - maximum 35 1/2 inches long), and choose a standard depth (front edge of the sill toward your window: 2.25", 3.25", or 5.25").

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 a white outdoor grade U.V. material to resist yellowing. 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 of my original Sill Shield™ is superior to any imitation product, 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 [email protected] and please send a picture if possible.

Amazing fix
I have 4 large dogs who LOVE to look out the windows and 'znnounce" passers-by. Their claws have done an awful number on the window sills (which i tried to protect with custom cut acrylic but that didn't protect the edges). Gary's product completely cover the top and edge of the sills and they fit perfectly!

An easy permanent brilliant fix!
Night and day. I rent this house from my sister and she saw the damage on the windowsill and never said anything until I showed her the before and after and she said “thank god! I was wondering how I was going to fix that come time to sell! Like new and will stay that way. Awesome awesome awesome.

You can actually talk to the owner
I called on a Monday morning with several questions. Gary answered and all my questions were satisfied. I put in an order for eleven sills in three different custom lengths. I received the order on Friday. They were cut exactly as ordered and plenty of the 3M coins were included. I won’t have to worry about repairing the sills and the little guy can now have free run of the entire first floor.
