How To Tell Where Water Is Coming Into Basement

Finding out where water is getting into your basement is key to fixing the problem. Try these tips to find leaks and protect your basement from water damage.

Leaking basements can lead to musty odors, mold and mildew growth, and structural damage to your home. To prevent these problems, it's important to fix basement leaks as soon as possible. But before you can fix a leak, you need to find out where the water is coming from.

Check the Foundation Walls

One of the most common places for water to enter a basement is through the foundation walls. Cracks in the foundation can allow water to seep in, especially during heavy rains or when the ground is saturated. To check for cracks, inspect the foundation walls carefully. Look for any signs of water damage, such as efflorescence (a white or chalky substance that forms on the surface of concrete) or mold growth. If you find any cracks, seal them with a hydraulic cement or epoxy.

Inspect the Window Wells

Window wells are another common entry point for water. If the window wells are not properly sealed, water can seep in around the edges and enter the basement through the window. To check the window wells, remove the covers and inspect the wells for any cracks or gaps. Also, make sure that the window wells are properly graded so that water drains away from the house.

Look for Leaks in the Plumbing

Leaks in the plumbing can also cause water to enter the basement. Check all of the plumbing pipes in the basement for any leaks. Also, check the water heater and sump pump for any signs of leakage. If you find any leaks, tighten the connections or replace the pipes.

Inspect the Sump Pump

The sump pump is responsible for removing water from the basement. If the sump pump is not working properly, water can accumulate in the basement and cause flooding. To check the sump pump, make sure that it is plugged in and that the discharge hose is clear. Also, test the sump pump by pouring a bucket of water into the sump basin. The sump pump should turn on and pump the water out of the basin.

Check the Grading Around the House

The grading around the house can also affect whether or not water enters the basement. If the ground is graded towards the house, water can pool around the foundation and seep in through the walls. To prevent this, make sure that the ground is graded away from the house so that water drains away from the foundation.

Call a Professional

If you cannot find the source of the water leak, call a professional. A professional plumber or basement waterproofing contractor can help you find and fix the leak.
