We Manufacture “Unbreakable” Window Well Covers – Any Shape & Size


The short answer is – Yes. They are made of high-grade polycarbonate. Due to being a window well cover manufacturer for over 40 years, we special-order this extended life clear unbreakable sheet. Other manufacturers will state their plastic has a UV inhibitor, but this will only last about four years when it turns yellow and eventually brittle.

Our clear polycarbonate covers can withstand the force of a sledgehammer blow. Even better, they withstand the challenges of any weather conditions! Guaranteed resistance between 130 and – 40 degrees Fahrenheit.

All of the covers on are custom-engineered and made to fit your window well perfectly, no matter the shape, size, or style. We’ve helped clients solve their unique window well problems that traditional covers could not. Our window well covers come in various styles, including clear polycarbonate covers and aluminum grates.


Our window well covers are custom-engineered to fit ANY shape and size! They can be extra-large for industrial and community buildings and extra small, suitable for a family home. One of the smallest covers made so far is a polycarbonate cover 17″ x 5″, almost the size of a sheet of paper.


Window well located in an unusual place? We can help by creating custom egress solutions with hinged tops to allow easy emergency exit. We can build not only an egress-compliant window well cover but provide a complete egress window kit that is just right for you.


Don’t worry! Our experts will help you decide on the right window well solution to cover your basement wells beautifully.
