This page explains how water can seep into your crawl space, why it’s crucial to tackle it quickly, and how Bay Area Underpinning can help resolve these issues. 

Understanding Crawl Space Water

Water in a crawl space refers to any kind of standing water found beneath your house. This might be puddles of water brought on by flooding, or even just damp soil. 

Water in your crawl space can lead to several problems, including: 

If not addressed, these issues can worsen. Bay Area Underpinning is adept at handling moisture concerns in crawl spaces, removing existing water, and preventing future water entry. 

Why You Have Water in Your Crawl Space 

Most crawl spaces have outdated designs that make it easy for water to get in. There are several ways water can get into your crawl space: 

  • Open Vents: These can allow moisture-laden air inside. 
  • Weather Conditions: Rain or floods can seep through walls, corners, the ground, and vents of the crawl space. 
  • High Groundwater Levels: High water tables or rising groundwater can contribute to moisture issues under your home. 
  • Inadequate Drainage: Poor landscaping, gutter problems, clogged drains, and missing moisture barriers can lead water into your crawl space. 
  • Plumbing Issues: Leaks from pipes or water heaters and minor breaches in supply lines can cause water pooling. 

Bay Area Underpinning conducts thorough assessments to pinpoint all contributing factors, ensuring comprehensive solutions that address the root causes of crawl space water.
