"Service was great from sales, to installation, to post installation support. Very responsive, very professional. It's hard to find in this 'space'--there are a lot of shady people in basement water damage/repair, and this place exceeded expectations. We've had our repair in place for 4+ years, with only 1 small issue on a wall seam crack, and that was fixed within 24 hours of reporting the issue. Stand up place! Thank you for such great service and support."

Basement Waterproofing questions, answered by experts

In most cases, yes, because the large majority of basements leak or will have moisture issues at some point, and waterproofing methods can mitigate that risk or eliminate it entirely. Plus, water and moisture issues can be quite problematic, as they can lead to mold growth, rotting of building materials, structural damage, poor indoor air quality, increased electric bills, and other problems.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

Crawl space encapsulation typically lasts between 10 to 20 years. If you experience a catastrophic event, like a flood, or poorly encapsulate your space with low-quality materials, it may only last a decade. Otherwise, as long as you properly maintain your crawl space, a high-quality encapsulation can last more than 20 years.

In many cases, yes, a damp basement can be bad for your health. Not only can damp air affect your lungs, but it can promote mold growth and pest infestation. Mold spores can be dangerous to breathe in, as can waste particles from insects and rodents attracted to the moisture. Damp, moldy air can also move up into your living area. As such, it’s crucial to fix any basement moisture problems as soon as they crop up.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.
