"I was glad John's Waterproofing was recommended to me to resolve the serious water problem in my large crawl space. With Jake's Design and Jeremy's remarkable crew, who were able to efficiently perform the many tasks needed to fix the problem, I now have a dry, clean and healthier crawl space under my home. Thanks to John's superb 5 star Company! Virginia Rossman"

"Great to work with! The crew came with many skill sets to accomplish a complete front and backyard landscape design project with sod, irrigation, flagstone fire pit area, and landscape lighting. The plants and trees provided were a good variety, healthy, and a great value given the size of the trees. Hope to work with them again on future projects."

Basement Waterproofing questions, answered by experts

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

Pooling or standing water in your basement should be cause for alarm and action. This indicates that there is a leak or a drainage issue, and until you repair the root of the problem, the situation will only happen again or grow in severity. It’s important to deal with water damage as soon as it occurs.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage.
