Steps of Crawlspace Encapsulation

The construction engineers and scientists recommend to encapsulate, or seal, the crawl space to turn this dirty and moldy place into a comfortable area where there is no mold or damp.

This is one of the best solutions to avoid the issues with indoor moisture. How to encapsulate crawl space in your house?

Crawl space encapsulation (or sealing) is similar to the lining in swimming pools that prevents them from leaking. Every other crawlspace has its unique moisture challenges and issues.

  • Insulation
  • Vapor Barrier
  • Sealing & Ventilation
  • Drainage System
  • Dehumidifier

Insulation. The first task in the process is installing foam boards on the walls, and then, covering them with a vapor barrier. That is done to block moisture from penetrating into the crawl space.

Vapor Barrier. It is a thin sheet of plastic that is located under the house to cover the ground and the crawl space walls. It blocks out the moisture.

Sealing & Ventilation. Many contractors understand that the crawl space should be considered as the part of a living area. That’s because most of the air we breathe at home comes immediately from the crawl space. That is why this area should be treated appropriately with sealing, insulating, and keeping free from damp and moist.

Drainage System. That should be added to the encapsulation if your area has a high water table and/or the crawl space is located below the ground level and suffers from water seepage.

Dehumidifier. Protect your crawl space from extensive humidity and all the related issues penetrating into it with the help of installing a humidifier in this area.

  • Inspect, clean, and dry out the crawl space
  • Repair and seal foundation, cracks, and vents
  • Install drainage system, insulation, and vapor barrier

Additional Crawl Space Waterproofing

  • Water Removal
  • Finishing
  • Basement Encapsulation

Water Removal. Water that gets into the crawl space should be removed. The water normally penetrates into it because of heavy rains, cracks in the foundation, flooding, and misdirected or clogged gutters.

Finishing. The finished crawl space appears quite beneficial for a better house appeal while selling it as well as for saving energy and improving the quality of the indoor air.

Basement Encapsulation usually includes:

  1. The walls waterproofing with cement.
  2. The foundation sealing.
  3. A sump pump or drain installation.
  4. Repairing cracks with epoxy injections.
  5. The downspouts managing and soil grading from the outside of the house.

How we work

Why Should You Choose Tornado Plumbing & Drains?

Guarantees and warranties you can count on


  • Can I fix/repair/do it by myself?

    Yes, you can fix yourself one small area, but it really depends on your particular problem. As a full service crawl service contractor, we offer several solutions, both from the interior and exterior, as opposed to a one-size-fits-all system. Our Basement Advisors are trained to recommend the most practical and economical solution.

    Should I fully encapsulate my crawl space?

    The full encapsulation is needed when the amount of standing water is rather significant, and when moisture or high humidity creeps through the foundation. This type of repairs and installation provides a great bonus of saving energy as well as the possibility to fully control the moisture.

    Does an encapsulated crawl space need a dehumidifier?
