Every homeowner wants to avoid basement flooding. In a previous article, we discussed how to prevent and repair basement water leaks. This page answers the question, “Is a flooded basement dangerous?” Before you worry, learn the facts and what to do if you face this worrisome situation.

Is Basement Flooding Dangerous?

Basement flooding can be extremely dangerous for several reasons and should be avoided until a basement waterproofing expert examines the situation. Electrical wires, fixtures, and appliances that are in contact with water can pose a risk of electrocution. Standing water should be avoided until it can be safely removed and the source can be accurately identified. 

Is it Safe to Live in a House with a Flooded Basement?

It is unsafe to live in a house with a flooded basement for these reasons:

  • Mold and Bacteria Presence: Floodwater is a breeding ground for mold growth and bacteria, which can cause significant respiratory and other health issues.  
  • Water Contamination: Floodwater can contain toxic chemicals, sewage, and bacteria and pose dangerous safety and health risks. 
  • Potential Carbon Monoxide Poisoning: Using portable generators indoors during a power outage can cause carbon monoxide poisoning.
  • Electrical Hazards: Standing water poses an electrical hazard. If electrical outlets, appliances, or wiring come into contact with water, electrocution risks increase.    

Evacuate your home and avoid entering the flooded basement until a basement waterproofing professional can assess and address the situation safely. Following these recommendations prevents dangerous outcomes for you, your family, and your home.

Exceptional Service and Trustworthy Company I want to express my heartfelt gratitude to Cody and his remarkable team at AFS. When the initial installation fell short, they stepped in with unwavering dedication. Cody personally assessed the situation, and his team worked tirelessly to fix all the issues. The best contractors were mobilized, and they expedited the resolution. Not only did they address the technical aspects, but their commitment to customer satisfaction was extraordinary. Cody went above and beyond, ensuring that we were completely satisfied. He met with us face-to-face, patiently addressing our concerns and making certain that every detail was taken care of. Itâ  s rare to encounter such personalized service in todayâ  s business landscape. What truly sets AFS apart is its integrity. It stands by its product and its word. Its veteran-friendly ethos isnâ  t just a marketing ployâ  itâ  s genuine. But it doesnâ  t stop there. AFS is also family-oriented, inclusive, and rooted in human values of faith. I wholeheartedly recommend it for its exceptional work, outstanding team, and unwavering commitment to its customers.

My experience with GroundWorks was AWESOME! Michael came out within a week for an estimate, made a quick and thorough survey, and explained my options with recommendations in detail. Clem, Garrett, and Nick came out, less than 2 weeks later, to install sump pumps in the crawl space and encapsulate the lower portion. Right from the start they had a great attitude, clearly described what they were going to be doing, and attacked the project. They completed the work in half the estimated time! I was given progress reports with detailed pictures each step of the way. After the work was completed, they tested the system and gave me easy to understand information on how to check the status of the components and basic upkeep. I was NOT looking forward to getting this work done as it was a complex, extensive problem I wasn't sure had a good solution. The way they broke it down, communicated, and completed the work so efficiently not only put me at ease, but also made it a joy. The work solved that problem of excess water AND added significant value to the house overall. I'd buy stock in these guys if I could!
