Types of Egress Window Wells

These wells are generally easy to install, fairly light weight and their single piece construction make them nearly completely leak proof.  Due to the size and symmetrical shape, it’s easy to purchase a tight fitting cover for these wells.  Typically, they’re the most economical and combined with a polycarbonate cover it’s easy to keep leaves, debris, rodents from falling in the well.  Steel wells are usually white but can be found in various painted options including a stone look.   Sizes and shapes vary from square to rounded corners and are offered in a variety of sizes that meet code requirements.

Like steel wells plastic wells are typically easy to install, lightweight, and have a single piece construction that minimizes leaks and penetration of water and debris.  They can cost twice as much as a steel well but offer several options and colors that mimic a natural stone or rock retaining wall.  Many of the manufacturers’ designs incorporate steps in the well itself that eliminates the need to buy a ladder since the steps are built directly into the well itself.  These wells are very rigid and offer a virtually maintenance free option for egress window wells.  Some designs even offer terraced steps that you can utilize for planting and gardening beds to offer some colorful interest just outside the basement window. Like steel wells there are limitations to maximum available widths and depths.

Custom wells offer endless possibilities and options for window wells. Timber wells are generally constructed using treated 6”x6” timbers and can create virtually any size well and have minimal limitations in relation to height, width, or depth. It’s uncommon for timber wells to be any other color than natural wood. Steps can be constructed using the timbers so it’s not necessary to purchase a ladder. Like the plastic or fiberglass wells, timber well construction can offer terraced steps to be utilized for plant beds.

Man-made or concrete blocks can offer a beautiful well that also has little to no limitations in regard to height, width, or depth. However, it is important to understand that these materials do require geogrid or some type of tie-back when the wall design exceeds a certain height. A general rule of thumb is when the wall is greater than 4’ it’s necessary to incorporate geogrid or tie back. This translates into more excavation of soil and more labor for proper wall construction. The available array of colors, textures, and sizes allow the homeowner a multitude of options to create a personal look that’s unique to them.

Natural stone wells, like block wells, offer stunning opportunities to craft an amazing natural back drop and a one of a kind view out the basement window. Certain stones will work better than others but like timber and block, larger spaces can be constructed verses the pre-made single piece wells.

Poured concrete walls also offer another option when larger wells are necessary and have a clean simple look.
If you decide to go with a custom egress window well, the most important aspects that need to be addressed are drainage and the base/foundation. Often, wall failures are caused by an inadequate base or lack of drainage behind the wall. An insufficient drain zone behind the wall can cause hydrostatic pressure and eventually cause the wall to fail.
Also, keep in mind that a custom wall will be harder to cover due to the size and potentially with natural stone an inconsistent surface for the cover to rest on. Be prepared to clean leaves, debris, rodents, trash, and whatever else may blow across or roam through your yard.
