“Unbreakable” Sloped Window Well Covers

Our custom-styled sloped window well covers are made to shed water, dirt, and debris away from your home. Installing a Sloped cover is one of the best solutions for keeping basement window wells clean, dry, and clear. At Window Well Experts, we are incredibly proud of the performance of our custom-designed Sloped cover, which is our best-selling product of all time. 

Sloped window well covers are made from “unbreakable” Polycarbonate

Polycarbonate has 250 times the impact resistance of glass and 30 stronger than the other popular clear plastic, acrylic. The material is lightweight and easy to manage. In addition, the crystal clear Polycarbonate allows the maximum amount of light into the basement. Finally, the cover provides an easy exit in case of an emergency. 

This cover has up to a 2″ slope, and the sleek one-piece cover clips onto the lip of the well. The cover releases with a push-up from below or a pulling-up motion from above for routine home maintenance or emergency escape.


Product Features:

  • Safely supports 400 pounds.
  • UV treatment protects your custom-made window well cover from exposure to the sun and prevents yellowing over time.
  • With its clamshell design, it is self-cleaning—sheds water and debris away from your home.
  • Keeps snow and rain, dirt, yard debris, and animals out of your window well.
  • Made to fit your window wells, not someone else’s idea of “standard.”
  • Durability – lifetime warranty
  • Rust-free aluminum framing
  • Rust-free construction: aluminum – bracing, with stainless steel hardware supplied with every order.

Wonderful! The process was quite easy, and the customer service and communication was excellent. Candi and Rick helped us quickly and made sure we were satisfied with our order. We have huge window wells and we were very happy they were able to accommodate us! Most of all, I am very happy to no longer worry about people, or animals falling into the wells. They look BEAUTIFUL, so glad we chose the super slant, and it really finished off the look of our patio.

A big thank you, keep doing what you're doing, we need more companies like you.

The egress window well cover fits perfectly. I no longer have to worry about my kids and the neighbourhood kids playing near my front porch. During a big rainfall, the well stayed completely dry. The cover is lightweight, strong, looks amazing, and made in Wisconsin, USA.
