Custom sized windowsill protectors, available in clear or white. Choose your custom Sill Shield™ width (left to right along the length of the windowsill) and depth (front edge of the sill toward your window). 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 white outdoor grade vinyl, the same durable, U.V. resistant material used in vinyl siding. 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 and durability of my original Sill Shield™ is superior to any alternative, 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 SILLSHIELD@YAHOO.COM and please send a picture if possible.

Just what I was looking for!
I have 3 dogs at home that love looking out the windows in our front office, but when they notice anyone walking by with other dogs or strange vehicles, they have a bad habit of standing on the window sill. This was destroying our window sills! The paint was coming off and there were scratches from their nails. I was searching for anything I could put down to protect the wood and came across this product. It was exactly what we needed to protect from further damage. The package arrived in less than a week, and my custom sized sill shields fit perfectly! We are so happy with this product!

Exactly what I was looking for!
This is a genius product! I searched and haven't found anyone that does what Sill Shield does! I thought I'd only need one for the window my dog jumps up on, but now I want to order more for my other windows. The white color blends in so well you can't tell it's there.

Great company to work with!
Great product, more rigid and sturdy than expected. Very surprised how amazing they look! They blend right in. I was worried they would look cheap, definitely not the case here! Their design actually looks better that my original sill. Tried two to try and will be ordering the rest of the sills for sure. Two big dogs jumping on them for a few weeks now, not one scratch on them. Love this product and would definitely recommend it! Also love the way they treat their customers!

Excellent Product
I purchased this product to protect the windowsill next to my front door and so far so good. Processing and Shipping was prompt. Received my order within less than 5 days. I had questions about product measurements and received a call back immediately after leaving voicemail. Product was so easy to install, instructions were included in case it was needed. So far the windowsill protector is holding up well and when my almost 50 lb pup stands on it I know feel relieved to know the windowsill is protected. Completely recommend this product.

Works perfectly!
We ordered custom window sill protectors for an abnormally shaped window that our 55 lb dog LOVES to look out and scratch. I looked everywhere for something that would protect the sill, look nice and hold up to our dog when the UPS guy comes! ;) These were perfect! Gary worked with me so customize it exactly how we needed it and they look great- you can hardly notice them and are holding up well to our dogs abuse! The only suggestion/request I would have would be to include more of the sticky/velcrow things to secure the covers- we added some command strips to ours as our dog knocked them off a few times. Otherwise absolutely great product!
