Basement waterproofing is an important, often neglected service that is critical to the safety of your home. To understand the importance of waterproofing, you must understand what it is and what function it serves.

Most homes are built with basement foundations that are below ground level. As a result, it’s important to make sure the foundation is treated with proper water blocking methods. By waterproofing basement walls and floors, a barrier is created between the water and the interior of the structure preventing any water from entering into the basement. Blocking the water from entering must be backed by a functional water drainage system that can divert any water that makes its way in right back out. This is accomplished through sump pits with sump pumps that capture the water and redirected it back out of the property, releasing it at a safe distance away from the foundation.

The number one reason why people do not perform basement waterproofing is attributed to the cost of performing the service. However, you must consider the dangers associated with not protecting your home and how it can impact you both financially, and more importantly your health. Consider the following statistics released in a recent survey:

  • 65% of homes owners store valuables in their basement
  • Average basement flood recovery costs in Canada peaked at an all-time high of $43,000 per incident
  • The cost to waterproof a basement is less than half the average recovery cost
  • There are many government and not-for-profit organizations that are able to help subsidize some of the costs associated with basement waterproofing
  • Having a basement flood can create a substantial health risk in less than 24 hours after the initial flood occurs

It is a common misconception that insurance companies cover basement floods. Most insurance policies protect you when water originates from inside the house (burst pipe, overflowing sink, faulty appliance). However, most policies do not cover external sources such as severe floods, rains or overland water. Even if you opted for the additional flood protection in your policy, there are many exclusions to the coverage, and you can find yourself held financially liable for the damage.

If you were ever unsure if waterproofing a basement was something you should perform, you need to get a professional assessment of your property. You need to better understand the risks you are neglecting by not waterproofing your basement. We offer a free no obligations assessment that can help you better understand your risks and the benefits specifically suitable to your property. Not all structures are built the same and it is highly advisable you reach out and book your free assessment. It could end up saving you thousands of dollars in the future.
