5 FAQ About Basement Waterproofing

No one wants to find water seeping into their basement. It can lead to property damage, structural issues, and even harmful mold and mildew growth. Basement waterproofing can help you avoid this situation in the first place. If you’re thinking about investing in this service, here are answers to some frequently asked questions to help you make an informed decision.

Answers to Common Questions About Basement Waterproofing

1. What Are Some Signs That My Basement Is Leaking?

The most obvious sign is if you see water in your basement. However, there may also be a musty smell, saggy insulation, or moldy spots on the wall or other basement structures. It’s a good idea to look through your entire basement periodically, especially after major storms, to keep an eye out for any of these signs.

2. What Causes a Basement to Leak?

The most common reason why water makes its way into a basement is a buildup of water around the home, usually due to heavy rainfall, and an open entry point where it can seep in. Usually, this entry point or vulnerability is at the top of the basement wall, around the window wells, in cracks along the wall, or sewer pipes.

3. How Do I Know if My Basement Is Already Waterproofed?

waterproofingIf you’ve recently bought a house and aren’t sure if the previous owners had it waterproofed, there are a few signs you can look out for, like wall cracks that have been filled in or grading on the outside of the house to drain water away from the basement. However, it’s always a good idea to have a home inspection when you purchase so you can have a professional determine the level of waterproofing and what additional protection might be necessary.

4. What’s the Average Cost of Waterproofing a Basement?

The total cost of waterproofing a basement depends on the size of the space and the type of waterproofing service you need. You can expect to spend a few thousand dollars to complete this type of service for an average-sized basement.

5. How Long Does Waterproofing Last?

There are many different factors that impact how long a waterproofing solution can be effective. However, many waterproofers offer a 10-year warranty, so you can feel confident about it lasting for at least that long, or even more if it’s properly installed.
