"I was very pleased with the work that the Enviropro team completed in my basement with the installation of the drainage system. Mike took the time to really walk thru project details and answer any questions prior to the project. The team arrived onsite the first day of the job and walked thru to explain the work they would start. They communicated any questions throughout the project and I was highly pleased once the job was completed. I would definitely recommend Enviropro for basement waterproofing needs."

"Working with Just Dry Basements was best described as no-nonsense, fast, and high-quality. In a highly-charged emotional situation like a basement flooding - it is easy to just pick someone to do the work out of desperation. I was lucky enough to work with JDB, who not only rapidly assessed, made a plan together on how we would approach the job, and accommodated a difficult situation where the basement was mostly finished, and they had to carefully deconstruct some of the walls to put in the proper mitigation. A year plus later and a LOT of rain past, the work truly stands the test of time and whatever the elements can throw at it. I have since worked with JDB on other projects, and not just because of the quality of work, but also their fair pricing, friendly and predictable communication, as well as standing behind their work 100%."

Basement Waterproofing FAQs, answered by experts

Yes, a crawl space can add value to your home. However, there is a higher chance of it adding value if it is an enclosed crawl space, as this reduces issues caused by excess moisture in the home. That being said, a basement does add more value than a crawl space.

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

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.
