Mold Information for Property Owners

Mold Information for Property Owners, Managers, & Landlords

Maintaining a healthy indoor environment free of mold means that you respond to water leaks immediately. Water leaks can cause mold growth on materials, like the paper backing of drywall, carpeting, or wood products, in as little as 48 hours, causing health problems for your tenants and property damage for you.

Good Practice Recommendations for Mold

  1. Immediately fix the cause of the water leaks.
  2. Fully dry water-damaged areas and items within 48 hours to prevent mold growth.
  3. Use stainless steel, braided water fill line hoses for washing machine installations. Instruct tenants to shut off the hot and cold water feeds to the washer when leaving the apartment for extended periods of time.
  4. Inspect areas with high potential for water damage frequently:
    • Inside walls located at an exterior windows
    • Bathroom shower walls
    • Kitchen sink areas
    • Rooms containing washing machines
  5. If present, inspect landscaping sprinkler systems frequently for proper operation.
  6. Always vent clothes dryers to the outdoors.
  7. Even if not required, provide outdoor exhaust to bathrooms containing showers.
  8. Prior to extensive renovations due to water damage, perform analyses of the asbestos and lead content of building materials used in the house. Improper renovations that do not consider asbestos content of building materials and the lead content of paint can lead to contamination and violation of asbestos control regulations.
  9. Conduct a long-term radon evaluation of the building. Radon is considered the second leading cause of lung cancer in America, after smoking.

Mold Inspections

Although comparisons of indoors mold spore levels with levels outdoor may be helpful in determining risk, this type of air sampling can cost between $1,500 – $5,000.
