Drainage Issues: Why it Should Matter


So, the inspector has been to the property and discovered there are drainage issues. What does this mean? Well, for starters, if water is not properly draining away from the home, this means the water is settling somewhere within the home, most likely the basement or crawlspace. Why is this important to note? Not because we don’t want the deal to follow through, but because we as inspectors do not want to see the client subjected to one of the leading promoters of mold growth. After all, nobody wants to inhale mold spores for an extended period of time (at least not that I am aware of).


Mold, according to the CDC (center for disease control) causes noted symptoms in otherwise healthy adults and children. There is  ” sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheeze in otherwise healthy people; with asthma symptoms in people with asthma; and with hypersensitivity pneumonitis in individuals susceptible to that immune-mediated condition” (CDC.gov).


Since mold thrives in damp, humid atmospheres, it is a good idea to find out in advance if the home you wish to purchase has a drainage issue that will promote mold growth which could lead to serious health issues.



While detection of water intrusion may be a game changer, it is not always a deal breaker. There are solutions to issues that arise. Sometimes all that is needed is a better ventilation system or a change in humidity level. Small changes can help eliminate the risk – such as not carpeting lower level areas.  Drainage issues can sometimes be fixed by landscaping around the home. By grading around the home, this will shift the surface water. Sometimes, it is imperative to place a barrier in the water shedding layer of the soil to route the drainage in the proper direction away from the home.  Sloping away from the home’s foundation is the key.


Remember that water damage in a basement or crawlspace can be caused by any of the following:


  1. faulty plumbing
  2. failed sump pumps
  3. improper window installation
  4. leaking walls and foundation 


If the water is within the walls, then they most likely will need removed and replaced in order to prevent the growth of mold. Also, a professional waterproofing company may be able to assist in warding off any further water damage. There are 4 Types of Interior Waterproofing and a professional can help determine which type of drainage issue may be present and which type of interior or exterior waterproofing may be needed.
