Unnoticed water seepage in your crawl space is a silent threat that demands immediate attention.

This page explains the intricacies of water infiltration in your crawl space and why it’s crucial to fix the problem right away to keep your home safe and strong. 

What Is Crawl Space Water? 

Crawl space water indicates unwanted moisture accumulation beneath the main living area of your home. This may involve standing water or dampness on the soil or other surfaces of the crawl space. 

This water and crawl space moisture can lead to many problems, such as: 

Allowing water to linger in a crawl space deteriorates the structure over time. BQ Basements & Concrete understands the intricacies of crawl space challenges, addresses existing water problems, and prevents ongoing water intrusion. 

Why Your Home Has Water in the Crawl Space 

Many factors contribute to crawl space water infiltration, such as:  

  • Unsealed Vents: Open crawl space vents allow outdoor air to enter, causing moisture to condense on surfaces. 
  • Weather Effects: Intense rain, snowmelt, or flooding can lead to leaks through walls, corners, the ground, and open vents. 
  • High Water Table: A high water table surrounding the crawl space exterior can result in water infiltration. 
  • Drainage Problems: Issues like negative grading, downspout problems, clogged drains, and insufficient moisture barriers allow water runoff to enter the crawl space. 
  • Plumbing Issues: Leaks in pipes, malfunctions in water heaters, and pinhole leaks in supply lines contribute to the accumulation of water in the crawl space. 
  • Waterproofing Failures: Outdated or improperly installed systems and drainage issues in the crawl space can facilitate water intrusion through walls and floors. 

BQ Basements & Concrete identifies the underlying causes of water intrusion by conducting a free crawl space inspection, ensuring that all factors contributing to water infiltration are pinpointed. Our solutions effectively address the root causes of crawl space water infiltration. 

Can You Fix Crawl Space Water? 

Yes, water in a crawl space can be remedied with effective solutions. However, while water infiltration can be addressed effectively, removing standing water isn’t a lasting remedy. A comprehensive approach is crucial for long-term protection. 

BQ Basements & Concrete specializes in whole-home solutions that eliminate existing water and prevent future infiltration. Our approach goes beyond temporary DIY fixes and addresses the entire crawl space environment, creating a dry, healthy space. 

How BQ Basements & Concrete Fixes Crawl Space Water 

We resolve crawl space water issues by following several crucial steps: 

  • We begin with a free inspection to identify the sources of water intrusion and formulate a repair plan. 
  • Seal open vents in the crawl space and replace access doors to prevent further water intrusion. 
  • Implement interior drainage systems along the perimeter to capture leaks and groundwater. 
  • Install a crawl space sump pump in the lowest point of the area to collect and expel water. 
  • Apply drainage matting on the dirt floor to guide water toward the drainage systems. 
  • Affix insulation panels to the walls of the crawl space for temperature control. 
  • Encapsulate with a crawl space vapor barrier to isolate it from the ground. 
  • Integrate a dehumidifier in the crawl space to regulate humidity levels. 
  • Establish a regular schedule of annual maintenance inspections for continuous protection of the crawl space.
