Three Signs of a Wet Basement

Three Signs of a Wet Basement - Image 1

With many homeowners stuck inside due to the current pandemic, the timing is perfect to educate and prepare yourself for how to deal with a wet basement. Of course, no one wants a wet basement, but spring showers are on their way and we want you to be confident that your basement will stay dry!

We want to share some common signs that might indicate a wet basement in hopes you can identify them and give us a call for a permanent solution. If you can identify any of these signs (especially more than one!) or If you notice any type of water or moisture problems in your basement, then consider contacting TerraFirma, and we’ll provide you with a free evaluation of your home’s basement waterproofing problems.

Sign #1: Flooding Through Wall Cracks

One of the most common areas of water or moisture leakage in a basement is through the walls. Usually a side effect of the natural curing process of concrete, these cracks usually do not threaten the foundation. Even though this is a common problem, it does not mean it should be left untreated. When water starts to leak through your basement walls, it can quickly lead to a very serious flood in your home.

Be on the Lookout For:

  • Visible vertical cracks on the walls of your basement.

  • Water residue on the walls of your basement. This can look like an orange, minerally substance, reference photo below.  

  • Start by taking a walk through your basement…this is the time to do it! 

Many homeowners will often try to repair cracks by applying caulking material or epoxy. Unfortunately, this superficial fix does not stop water from filling the crack.

Sign #2: Leaky Basement Windows

A leaking basement window is another common sign of a wet basement. Maybe even a bit more obvious than a leaky wall crack, a leaky window is of equal concern.  Basement windows are often made using inexpensive steel or wood frames. As these materials age, they will begin to break down, showing signs of rust, corrosion, and decay. This can lead to windowpanes and even the frame itself to hang loosely causing an opening in your basement wall.

Be on the lookout for:

  • Water residue underneath your basement window.

  • Any openings around your basement window.

  • Consider the age of your basement windows. Have they ever been replaced?

Sign 3: Basement Leakage through Stairway

A leaking hatchway door can be a nuisance for homeowners who'd like their basement to be dry -- especially in a finished basement! A hatchway entrance is typically constructed separately from the rest of the home. This makes it vulnerable to flooding from many different areas.

Be on the lookout for:

  • Underneath metal hatchway doors.

  • Where the hatchway and foundation meet.


  • Through cracks in the concrete.

Now that you are aware of three identifiable signs that can indicate a wet basement, it is your turn to evaluate your space! But keep in mind that these are three common signs of a wet basement. Each basement is unique and therefore other signs may indicate that there is an issue with water or moisture.

The easiest way to create a peace of mind that your basement is the driest it can be is to walk through your basement and see if you can identify any of these signs. If there are no indications, then great! But if you have a concern, you know who to contact for a permanent solution.
