Types of Basement Damage in Southern Ontario and Southern Alberta

Common Causes of Basement Damage

Weather

Heavy rain and surface flooding can easily find its way into your basement. If your property’s soil and drainage cannot handle excessive water, it’s going to go somewhere—most likely inside your basement.

Poor Foundation Drainage

Your first line of defense against water leaks is exterior waterproofing solutions like gutters and downspouts. If either system is clogged, damaged, or unable to direct water away from your home, your basement will likely leak.

Hydrostatic Pressure

When soil around your foundation becomes saturated with moisture, it expands and exerts hydrostatic pressure, the constant force of water pressure on the foundation walls. If this force exceeds what the walls can withstand, it will cause cracking and inward bowing, compromising their structural integrity. Water then seeps through any available openings, including cracks and gaps around pipes or windows.

Internal Leaks

Your basement may contain plumbing pipes and appliances including washers and water heaters. If these essential items malfunction, leak, or burst, your basement could be inundated with water.

Sump Pump Failure

In the same vein, an outdated or failing sump pump system allows water to collect in your basement. If it lacks a proper lid, water can flood the floor, water vapor evaporates into the basement, and objects can fall into the pit and damage the pump.

Basement Waterproofing FAQs

Yes, by controlling moisture and humidity levels, basement waterproofing can help improve energy efficiency by reducing the workload on HVAC systems and preventing insulation from becoming compromised.

In most cases, standard homeowner’s insurance policies do not provide coverage for basement waterproofing or water seepage. However, if you have separate flood insurance, it may cover certain water damage resulting from flooding or excessive water intrusion into your basement. 

The cost varies depending on factors like the extent of damage and the specific solutions needed. You’ll receive an accurate price breakdown and financing options during a free inspection with a Groundworks expert.

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.
