Mold Growth in Homes under Wet Conditions

Atlanta Mold LLC News and Information

Interior environments of homes can be insulted by water events in a variety of ways. The most common include roof or exterior wall rain water penetration. Another common source of water includes water and waste water plumbing leaks.

Roof leaks are often associated with penetrations through the roof. This includes chimneys and associated flashing, vent pipes and gutters. Exterior wall defects leading to water entry are numerous. Windows, doors, exterior siding, and brick defects are often found to be the source. Both types of leaks may be hard to find and identify.

Anytime water staining is observed on the interior surface, it should be investigated immediately.

Self Help Recommendations

To identify possible moisture intrusion around your home, carefully inspect the perimeter of your foundation. Look for areas where the earth ground looks to have settled next to the foundation. Landscaping by planting trees and bushes next to the house usually results in a loose and permeable soil.  Overtime this loose soil will settle resulting a downward slope towards the house.This allows rain water runoff to saturate the soil hence the foundation.
