How to Repair a Leaking Basement Window Well
A leaking basement window well must be repaired as soon as possible to avoid basement floods. While basements are extremely useful rooms in a house, they are susceptible to damage from flooding and dampness. Most of the maintenance and repair work in a house targets the basement.
If you have a flooded basement, the two mostly like reasons are either that water is seeping through a crack in the foundation or that water is coming through a leak in the basement window well.
Concrete foundations usually do not crack and let in water. Your flooded basement is most likely caused by a leaking basement window well. Fortunately, basement window wells are not hard to repair. Here’s a step-by-step guide for repairing a leaking basement window well.
Step 1 - Examine the Windows
Closely inspect all of the windows for damage including cracks and holes around the windows. If you find a crack, make it slightly bigger. Use a chisel to dig it open some more and a sledge hammer to chip away the sidings. Wear protective eyewear to prevent injury from stray cement chips.
Step 2 - Fill the Cracks
Once you have enlarged all the cracks and holes, fill them with cement. Combine 5-parts cement with 1-part water into a homogenous mixture. Use the cement mixture immediately after you have mixed it; the cement will begin to set within 15 minutes. Use a trowel to make sure that the cracks are tightly filled.
Step 3 - Install the Drainage Duct
If your basement has a large window well, drill a hole right under the window sill. Leave a few inches between the window sill and the hole that you have drilled. Drill the hole in such a manner that it opens right outside the home. Doing so will allow you to drain the water from the basement completely.
Place the metal pipe that will act as the drain into this hole. The hole should be the same size as the diameter of the pipe so that the pipe can fit snugly into the drilled hole.
The pipe should rest halfway between the inside and outside. Place the metal grate over the pipe’s exterior end so that dirt and debris cannot block the outlet. Finally, install the well duct over the protruding pipe.
