Types of Crawl Space Damage in Southern Ontario and Alberta

Common Causes of Crawl Space Problems

Stack Effect

The stack effect is a phenomenon where warm air inside your home rises and escapes, causing a vacuum that pulls colder air into your crawl space. 

This leads to high humidity and energy costs if your crawl space is not properly sealed and insulated. Humid air drawn condenses, causing mold, wood rot, underscoring the importance of ensuring your crawl space is well-maintained.

Soil Washout

When soil erodes, it reduces the support for the foundation, potentially causing settling or uneven floors above. This destabilization not only threatens the structural integrity of the home but can also lead to gaps and cracks in the crawl space walls, inviting moisture and pests that can further damage the 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.
