Basement Waterproofing questions, answered by experts

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.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

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.

Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile.

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.
