If you have a basement with windows that are below ground level, you probably have window wells. Window wells are necessary to provide access to the windows and allow natural light to enter the basement. However, without proper protection, they can become a hazard and a source of water damage. Installing window well covers is an essential step in protecting your basement and increasing your home’s safety. In this article, we will guide you through the process of installing window well covers.
Measuring the Window Well

Before you start shopping for window well covers, it’s essential to measure the window well’s dimensions accurately. You’ll need to measure the length, width, and depth of the window well. Don’t assume that all window wells are the same size. They can vary significantly, even in the same home.
To measure the window well, start by cleaning any debris or dirt from the interior of the well. Use a measuring tape to measure the length and width of the window well at the top. Then measure from the top edge of the well to the bottom to determine the depth. Record the measurements accurately, as they will be used to select the right size cover.
It’s essential to measure the window well correctly to ensure that the cover fits snugly and provides adequate protection. A poorly fitting cover can allow debris and water to enter the window well, defeating the purpose of installing a cover in the first place.
Choosing the Right Cover
Once you have the measurements, it’s time to choose the right cover. There are several types of window well covers available, each with its advantages and disadvantages. The most common types are made of polycarbonate, acrylic, or metal.
Polycarbonate and acrylic covers are lightweight and durable, and they allow natural light to enter the basement. They also come in different colors and styles, so you can choose one that matches your home’s exterior. Metal covers are stronger and more durable than polycarbonate and acrylic covers. They can support more weight and provide better protection against debris and intruders.
When choosing a cover, consider your budget, the level of protection you need, and the type of window well you have. Make sure to measure the cover to ensure a proper fit. A cover that’s too small won’t provide adequate protection, while a cover that’s too big can be difficult to install and may not look aesthetically pleasing.

When choosing a cover, consider your budget, the level of protection you need, and the type of window well you have. If you live in an area with high precipitation, a cover with a slope can help direct water away from the window well. If you have a basement egress window, choose a cover that can be easily removed in case of an emergency.
Measuring the cover is also crucial to ensure a proper fit. Place the cover on top of the window well and make sure it covers the entire well. The cover should not extend beyond the well’s edge or interfere with the window’s operation. If the cover is too big, it may be challenging to install and may not provide adequate protection. If it’s too small, it won’t cover the entire well, leaving some parts exposed.
Preparing the Window Well
Before installing the cover, it’s essential to prepare the window well. Cleaning the window well is the first step in preparing it. Remove any debris such as leaves, rocks, or dirt from the bottom of the well. This will prevent the cover from resting on top of debris, which could damage the cover or prevent it from fitting correctly.
Next, remove any obstructions from the window well, such as branches or shrubs that may interfere with the cover’s installation. If you have a window well liner, make sure it’s securely fastened to the foundation and doesn’t move when you place the cover on top.
Ensuring proper drainage is also vital to prevent water from pooling in the window well. If the window well doesn’t drain correctly, it can lead to water damage in the basement. Check the drain for any debris or clogs and make sure it’s functioning correctly. If necessary, install a drainage system to direct water away from the window well.
By preparing the window well correctly, you’ll ensure that the cover fits correctly and provides adequate protection. It will also prevent potential water damage and increase the safety of your home.
Installing the Cover
Once you have chosen the right cover, it’s time to install it. Start by cleaning the window well thoroughly and removing any debris or obstructions. Place the cover on top of the well, making sure it’s centered and level. If the cover comes with clips or fasteners, secure it in place according to the manufacturer’s instructions.
Check for proper fit and seal. The cover should fit snugly against the window well and provide a tight seal. You can test the seal by pouring water over the cover and observing whether water seeps through the edges. If the cover isn’t sealed properly, you may need to adjust it or add weatherstripping to create a better seal.
Maintenance and Safety
Regular maintenance is essential to keep the window well covers in good condition. Check the covers periodically for cracks, holes, or other signs of wear and tear. Clean the covers with soap and water to remove dirt and debris. If you notice any damage, replace the cover immediately to ensure continued protection.
While window well covers provide significant benefits in terms of safety and protection, they can also pose some risks. It’s essential to take safety precautions when using window well covers. Keep the covers free of debris and snow to prevent them from collapsing under the weight. If you have children, make sure they don’t play on or around the covers, as they can be slippery and dangerous.
During the winter months, you may need to remove the covers to prevent snow and ice buildup. Store the covers in a dry, secure location to prevent damage. When reinstalling the covers in the spring, inspect them for any signs of damage or wear and tear before installing them.
