If you have wall cracks in your basement, it is likely that your home has a leak and will require immediate attention. Water damage can cause major structural issues within your home and lead to the formation of black mold and other harmful substances that can threaten your health.

Luckily, Pittsburgh Drain Guys offer various waterproofing solutions to repair your leaks and help keep your home safe and dry.

Lack of Occupancy

If your home was left unoccupied for a long time before moving in, it could lead to wall cracks. While wall cracks can be a concern, they are not a significant issue if caused by a lack of occupancy.

When people inhabit a home, they change the internal climate using air conditioning, heating, humidifiers, and dehumidifiers to keep the home’s temperature and humidity at reasonable levels. Without people inhabiting the house, these factors go unchecked, causing fluctuations that can cause the drywall to crack. In most cases, this type of damage is just cosmetic, but be sure to have your home inspected to make sure there are no significant underlying issues.


Wall cracks can also be formed simply due to your home settling over time. All homes move subtly over time, which can lead to wall cracks in areas throughout the house. The most noticeable areas where wall cracks can be found due to settling is over windows and doors. Wall cracks from settling are not an indication of a more significant structural issue and are completely normal.
