4 Types of Water-Intrusion Problems in Rental Properties

Water-intrusion problems in rental property can be a major cause of alarm for property managers, so this week’s maintenance tip from Keepe offers some helpful ideas.

This can be caused by many things, including faulty waterproofing during construction, poor drainage, incorrect water structure, and more commonly, the age of the property.

Next time you need to tackle water intrusion at your rental property, take note of these areas of concern.

Problems caused by water intrusions problems in rental property and leakages

Water intrusion in rental property can be disastrous on many levels, especially any part of the structure that is wood. Water damages wood, making leakage a major concern.

Secondly, water leakage causes a health threat to the occupants of the rental property; it can enable mold to grow when it goes undetected, and it provides a breeding ground for mosquitoes and other insects. If a substantial water leak comes in contact with electricity, there’s also the danger of electric shock or electrocution.

Why basements and crawl spaces leak

Basements and crawl spaces are the places most susceptible to water intrusion. In property management, it is critical to be keen about the following:

  1. Construction codes: These are the regulations that govern the design, construction, alteration and maintenance of structures. By adhering to these standards, you will uphold the health, safety and welfare of building occupants and, in this case, avoid water intrusion.
  2. Proper drainage: A faulty drainage system can result in water intrusion in your property. This is why it is important to make sure your drainage is well-structured, because while a water intrusion may take a long time to manifest, when it does, it will cost more to repair.
  3. Problems with water vapor: A family of 4 people yields about 3.5 gallons of water vapor on a daily basis, aside from the water vapor generated by activities like cooking, ironing and other heat-generating activities. Indoor air quality is affected by moisture. If water vapor is not managed well, the result is that mold can form in the room. There is also condensation and an increase in dust mites, which can be a big cause for concern.
  4. Waterproofing: Water intrusion can sometimes come through the floor of the basement. This is an indication that the waterproofing part of the original build of the floor was not efficient. If your property is in the process of being built, there is still time. However, if it is an existing property and you notice water intrusion from the floor, the floor has to be replaced.


The water-intrusion in rental property threat should always be considered because of potential consequences to both occupants and property. To be vigilant, routine maintenance practices are a must.
