Basement Waterproofing questions, answered by experts

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

Water damage always poses the risk of mold, but if you act quickly enough (within the first 24 hours), you may be able to avoid mold growth resulting from water damage. Clean up the water quickly and thoroughly dry the area. If the issue is more extensive or you didn’t act quickly enough, it’s always safer to assume mold has grown and hire a mold inspector to examine the area.

Yes, you can enclose your crawl space. Enclosing your crawl space can promote energy efficiency and reduce the risks of pests and mold by limiting factors like humidity. It can also reduce heat loss, which is why doing so for the winter can make your home more comfortable.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

The easiest methods for waterproofing your basement include installing a gutter system to direct excess runoff away from your foundation and grading the soil away from your home to pull water away from the concrete. In some cases, these methods alone can be enough to eliminate water intrusion and moisture problems in your basement. If you have excessive rainfall in your area, though, you might need to employ more complicated solutions, like installing a French drain and a dehumidification system inside.
