Cleaning your gutters is a vital step in lowering the humidity in your crawlspace and entire home. Mold spores are everywhere and they are waiting for the right conditions to grow and give off spores that cause us breathing problems. 70% relative humidity is enough to activate dormant spores.
A home that has had the gutters overflowing has likely had many hundreds of gallons of water enter the crawl space. It can take years, if ever, under these conditions, for a crawlspace to dry out enough to stop mold growth. Building engineers estimate that thirty to as much as fifty percent of the air you breathe in your home has passed through the crawl space. This air may be picking up some undesirable things in its journey.
There is a simple way to check if your gutter drains are plugged up. Simply insert a water hose into the drain or gutter and turn it on. Water will back up if there is a blockage. However, this will not tell you if the drain is broken alongside of the foundation and pouring water into the crawl space.
Someone needs to inspect the outer edges of the foundation inside the crawl space for signs of water entry. Walk around your house and look for sunken areas of lawn right beside the house. These depressed areas are almost always caused by water movement or rodent tunneling.
Crawl Space Portland, and our parent company Nature First Pest Control, has over 27 years of experience in diagnosing these issues.
