Our sloped window well covers are built from heavy-duty polycarbonate with 250 times the impact resistance of glass. The self-cleaning slope sheds rain, snow, and yard debris before it can pool on top of the cover or clog the well.
Sloped covers are Window Well Experts’ best-selling product of all time, and for good reason. The clear polycarbonate panel is lightweight enough to lift by hand and still lets full daylight reach the basement window. Each one is sized for metal, concrete, plastic, or composite wells, and every sloped cover ships with a lifetime warranty.
The one-piece cover clips onto the lip of the metal well with stainless steel hardware and releases with a push-up from below or a pull-up from above for routine maintenance or emergency egress. Other well types use Dual Locks™ made by 3M as a velcro-type fastener that opens and closes easily. Larger egress-sized covers can be ordered with a hinge, prop-up bar, or escape hatch to meet local code, and locks are available for added safety.

Polycarbonate has 250 times the impact resistance of glass and roughly 30 times the impact resistance of acrylic, which is why a sloped polycarbonate cover built from these high-quality materials outlasts the plastic window well covers sold at big box stores. The 2″ slope sheds rain, snow, leaves, and other debris on its own, while clear polycarbonate lets natural light reach the basement window below.

Sloped covers sit at up to a 2″ angle and shed off water and debris, which makes them a strong choice for wells where you want the cover sitting close to the ground. Bubble covers are not customizable, made for specific-sized metal wells, and are ideal when the window extends above the lip of the well. If your window sits at or below ground level, a sloped cover is usually the better call.
The cover safely holds 400 pounds of static weight, so heavy snow accumulation, an accidental step, or a fallen branch won’t break it. Sloped covers aren’t built for foot traffic, but the strength is more than enough for what most wells see across a year. If you need a cover rated for walking on, a steel grate is the right pick.
Yes. The cover releases with a push upwards for emergency egress. Larger egress-sized covers can also be ordered with a hinge, prop-up bar, and escape hatch to meet your local code. Always check your local egress codes before installing any cover over an egress window.
Sloped covers are built for nearly any shape, size, or material of window well, including metal, concrete, plastic, and composite wells. Send your measurements through our free estimate form, and our team will engineer a cover for the well. Larger or irregular wells can be built in a two-piece or split design to make the cover easier to handle.
The lifetime warranty covers cracks or splits in the polycarbonate panel, broken aluminum parts, hinges, locks, and the clips that attach the cover to the well. If a covered component fails under normal use, we replace it.
Each sloped cover is built to your specific well, so the timing depends on the size and complexity of the order. Standard sizes typically ship in a few weeks; larger or more involved builds take longer. Our team confirms the timing when we send your estimate.

Well covers fit perfectly.
There was a young raccoon living in this well when I went to clean out the leaves in it.
He lost his winter home!

My experience with Window Well Experts was very pleasant. The measuring and installation instructions were easy to follow. You can tell that the window is quality engineered and manufactured. Candi and Matthew were very helpful every step of the way. My wife and I love how the window turned out and how it looks on the window well after I installed it.
Thank You Window Well Experts! You can count on us to give you excellent word of mouth advertising in the future.

Working with Window Well Experts was a joy! Their detailed instructions for measurement were very easy to follow. There customer service is fantastic as they followed up on our measurements just to make sure everything was correct. The covers arrived quickly and were super simple to install. I wish I would have know about them years ago, as I have been buying the cheap covers from the hardware store, which I had to replace almost every year. These should last forever!
