Crawl Space Repair - Detecting Signs of Water Damage in the Summer

Thursday, July 6th, 2017 by Jessica Dingle

SOMETIMES A WATER ISSUE IS OBVIOUS

OTHER TIMES YOU NEED TO LOOK FOR THE SUBTLE SIGNS THAT CAN SLOWLY CAUSE DAMAGE 

When someone calls our office, we have a set process that we follow. This helps us gather some information to best assist our design specialists. One scenario we often see during the summer goes as follows:

stains on foundation wall

"Do you have water or moisture under your home?" 

"No, I looked down there and don't see any water, it is just dusty and the vapor barrier is a little torn." 

The issue with this is if you are only checking the crawlspace when the weather is warmer, there is less rain and ground saturation present, so it ends up more difficult to see water issues. For this reason, we like to teach people the signs that can be found during the warmer months so they can keep an eye out for water problems year-round. 

  • Sagging and falling fiberglass insulation: If you are under your home and see sagging and falling insulation it is likely due to moisture that has evaporated from the dirt under the home and that water weight is pulling it down. 
  • Look for mud or caked-on dirt on the existing vapor barrier or foundation walls: This is an indication that water has been on top of the vapor barrier repeatedly. 
  • Look for rust-colored lines and streaks along foundational walls, or for white chalky residue. This is an indication of water or moisture that has begun to seep through walls and create mineral deposits. 

These are indicators that water intrusion is an issue in your home and could lead to foundational issues as well as mold and other harmful indoor allergens. If you see any of these signs when you are quickly screening your crawlspace, call us for a free inspection on cleaning and protecting your crawlspace.
