Basements provide additional storage space, places to gather and entertain, or other uses. They are often the colder part of a house and weather elements can seep in without your knowledge. Buying a home with a basement? Here are some tips on what to look for and how to fix a home that may have basement waterproofing issues in the Belmont, Denver, Charlotte, NC area.

Dampness and Cracks in Foundation

It is exciting to look for a new property and home! When you walk into the basement, you want it to have a nice smell, as this will be a place to possibly entertain guests or spend time in. If you smell a musty odor or it feels damp, there may be an issue. Look around on the floor and walls for water stains and cracks in the foundation. According to U.S. Waterproofing, if there are hairline cracks, they can be fixed easily by using a sealant to ensure you are waterproofing the basement walls from the inside. If the cracks are wider or show water stains, these will need to be tended to quickly, and you may need to call a professional for assistance.

Basement Windows

If you see a water line or water that has accumulated around the area of the window, this is not a good sign and you may be looking at a clogged window well drain or a more extensive problem. Thompson Exterminating recommends also looking around the outside of the house where the foundation meets the lawn and take note if the water is pooling. If it is, this will be an area of concern.

Walk Through After a Snow or Rain Storm

If you can walk through the house after a rain or snowstorm, check to see if there are leaks, water on the walls, or puddles where the floor and walls meet. Sometimes there may be ice freezing on the walls. If any of these things are happening, an expert should be called in to assess the extent of issues. This may help you decide if this home is a good buy for you or not. If you have already moved in, an expert can help you with an inspection of the basement to find the origin of the problem and give you estimates and advice for any needed repairs.

Mold Growing?

This is something that is NEVER good to see in a home. It can be black, green, white, or any color and indicates that there is an existing issue. Unfortunately, this means there is already a water problem to deal with and now a mold matter to treat. Refer to our article about Mold Here.

Preventative Measures

Putting preventative measures into place is the best way to avoid issues in the basement. According to Best Pick Reports there are a few ways to prevent basement waterproofing matters such as installing gutters, sump pump maintenance, air flow correction, using a dehumidifier, and regular inspections of the foundation.


If you decide to try to fix the issues yourself, there are basement sealers you can buy such as waterproofing paint and concrete coating. Contacting a basement-waterproofing contractor will be helpful for an inspection and treatment plan. No house will be perfect, but doing an extensive walk-through and inspection will save you headaches, time, and money down the road.
