Moisture in your crawl space spells mold growth, pest infestations, and wood rot on your floor joists. It compromises your home’s health and safety. Ignoring moisture intrusion isn’t advised as it might impact the structural stability of your property, leading to costly repair bills.

So what can you do? Store-bought dehumidifiers aren’t a sufficient solution and don’t address the causes of moisture in your crawl space, such as leaks, open vents, and high groundwater. Plus, entering this area of your home can be dangerous, especially if mold spores are present.

Groundworks’ crawl space repair solutions overcome these challenges. Our sump pumps, vapor barriers, commercial-grade dehumidifiers, and other patented products transform your wet crawl space into a drier and safer environment for your family.

What Is Crawl Space Moisture?

Moisture in your crawl space is any excess water that has accumulated in the area. Crawl spaces contain some moisture because they are close to the ground, but too much water from rain and other sources is a serious problem. If humidity exceeds about 55%, you’ll need help from an expert.

A wet, humid crawl space can cause these issues:

What Causes Moisture in Your Crawl Space?

Moisture might infiltrate your crawl space in the following ways:

  • Crawl spaces are naturally moisture-prone because of their exposed dirt floors and location in your home.
  • Alberta often experiences heavy rain and snowfall. This adverse weather can contribute to crawl space moisture problems.
  • Open vents allow moisture to enter your crawl space, while cracks around pipes and electrical conduits invite humid air into this part of your property.
  • Humid air condenses on cooler surfaces in your crawl space.
  • Leaks from walls and vents are often an entry point for rain and groundwater.
  • Damaged pipes in your crawl space could lead to additional moisture.
  • High groundwater might saturate the soil under and around your crawl space.
  • Inadequate drainage can cause rainwater and surface water to gather near your foundation, resulting in seepage.

Can You Fix Crawl Space Moisture?

The good news is that you can repair moisture in your crawl space. However, dehumidifiers and other products from the hardware store won’t do much. Besides, you should leave DIY crawl space repairs to professionals with the proper safety gear. 

Groundworks offers a range of crawl space repair solutions, including sump pumps and heavy-duty wall panels, that dry out this area and prevent moisture from returning. We’ll also identify the underlying cause of your water issue so it doesn’t happen again.

Cory came to my house, thoroughly evaluated the situation, explained the options to me, and patiently answered all of my questions. He is amazing. There was a crack in my basement wall that needed to be repaired. Paul (I think) did a good and clean Job. The repair was scheduled and completed exactly as was described to me. Great team! I’d definitely recommend this company to others.

Excellent service. Sales was pleasant and quote was thorough enough to proceed. The crew that came out to excavate, and install the interior and exterior basement systems was absolutely top notch – their work was neat and tidy, they showed up on time, and worked hard. To top it off, they (and all the folks involved) have to be the most pleasant contractors I’ve ever dealt with – and this is house #5 for us over the years! Thank you, Basement Authority. Highly recommend.

Yesterday we had our sump pump service by Ben and was very pleased with the work. He was knowledgeable and took care in his work. He was very friendly and explained what he was going to do. Very good at his job and we’ll ask for him if we need any work done in the future.
