Wet crawl space insulation negatively impacts air quality and increases energy bills, which are both major concerns for Alberta homeowners. If ignored, a damp crawl space will damage the structural stability of your home, which costs tens of thousands of dollars to repair.

Unfortunately, simply replacing the damaged insulation won’t fix the problem. Only a trained professional can identify the underlying moisture problem and safely enter the crawl space to repair it.

Groundworks’ comprehensive crawl space repair provides a safe and long-lasting solution. After a free inspection, we will seal water entry points and install patented waterproofing products to protect your home against further moisture.

What Is Wet Crawl Space Insulation?

Crawl space insulation can get wet and deteriorate when it soaks up moisture. Fiberglass insulation, which builders often use in crawl spaces, is most susceptible to moisture damage.

Wet insulation loses its efficiency, allowing the following problems to happen:

Causes of Wet Crawl Space Insulation

Insulation in your crawl space gets wet for various reasons:

  • Open vents allowing rain, melting snow, and humid air into your crawl space
  • High humidity and condensation
  • Plumbing leaks
  • Inadequate drainage
  • Flooding due to inadequate land grading or overflowing gutters

These factors can saturate your insulation, preventing it from working correctly. Persistent moisture without proper insulation or sealing makes the problem worse.

Can You Repair Wet Crawl Space Insulation?

Yes, but replacing your current insulation is just a temporary fix. You need to deal with the root cause of the problem—moisture intrusion.

Groundworks offers a complete home solution that tackles both the causes and symptoms of wet crawl space insulation. One proven method is to seal crawl space vents and other openings to prevent moisture from entering this area.

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.

The service provided was excellent. From the start when we installed the tester to the end when we got the mitigation system installed. The installers came on time, cleaned up, and was super friendly. Definitely will contact them again for our next house!

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.

Fantastic service from start to end. Professional sales call, follow up, and terrific work crew on site. Did an amazing job of raising and leveling my driveway. The crew took great pride and were even excited with the outcome. I HIGHLY recommend their work.
