Basement Window Leaking Problem? Window Wells Can Help
Window installations in a basement are great for natural light and ventilation, but improperly draining window wells can spell disaster during heavy rains. Due to improper grading and lack of waterproofing, rainwater can start to collect around foundation walls and leak through the window frame. Then, in no time, your basement starts to flood, and we all know the horrors of a leaky basement.
The solution: properly waterproofed window wells! Plus, correctly installed window wells allow for a larger basement window installation, better ventilation, and more natural light in your basement. Essentially, window wells are recesses in the ground that are dug around the foundation walls to help you install windows below the ground. However, more than replacing a window well alone is needed to solve the problem of a leaky window seal. When combined with a properly waterproofed foundation wall and vertical drainage system, window wells are the solution to a leaky basement window. Additionally, the weeping tile system needs to be in working order at the window wells’ base, allowing the proper drainage of water collected in the well.

Benefits Of Window Wells With Drainage

Natural Lighting
A fantastic benefit to a properly functioning window well is the natural light they provide to your basement. Most basements are below the ground and receive minimal lighting, but properly installed window wells allow you to install larger window openings in your basement to get more natural light all year!

Better Air Circulation
Basements can be musty and have a very damp smell due to the walls being constantly wet, but having more oversized windows can allow for better air circulation.

Emergency Exit
Basement window wells also serve as an emergency exit for dangerous situations like fire or burglary. Installing window wells gives you enough space to exit and reach a safe place in times of crisis.

Compliance with Law
Building codes and insurance policies now require residential buildings with basement windows to install window wells for safety.
Our Interior Basement Waterproofing Process
01
The first step in a window well repair is excavation. We manually excavate the soil to the required dimensions until we reach the weeping tile system at the footings. Then, we check the weeping tile and replace it if necessary.
02
We repair any cracks in the exposed foundation wall and apply a layer of primer to the exposed walls after thoroughly cleaning them with a wire brush. We then use a rubberized membrane, a fiberglass mesh layer, and another layer of rubberized membrane.
03
A layer of plastic is then applied, followed by a drainage board installation over the plastic layer. This helps to drain ground water towards the weeping tile system and protects soil backfilling.
04
The next step is to install a fresh 4-inch vertical drain from the weeping tile to the bottom ledge of the window well opening (at grade level). This vertical drain is vital to draining the window well during heavy rains.
05
We installed the window well in the pit and fastened it to the foundation walls. Then, the window well is appropriately installed and tightly attached to the foundation walls.
06
We then put around 8″ inches of ¾” clear gravel on top of the 4” vertical drain, and the exterior of the window wells are backfilled with the native soil. We then power tamp to ensure the natural grading is recovered.
