Crawl space encapsulation questions & answers

Should I encapsulate my crawl space?

Yes, you should encapsulate your crawl space as a preventative measure. Crawl space encapsulation comes with the following benefits:

  • Improved indoor air quality
  • Fewer pest problems
  • Usable storage space
  • Greater energy efficiency
  • More comfortable living conditions

Encapsulating your crawl space prevents water intrusion, making it so you don't have to worry about wood rot, mold growth, and so many other costly issues down the road.

When should you not encapsulate a crawl space?

Though it is beneficial to encapsulate your crawl space in most cases, you should not encapsulate your crawl space when you have standing water. When you have an excessive amount of water in your crawl space, placing plastic over it could be worse than doing nothing. The water will find its way on top of the plastic, leaving you with the same issue you started with.

Is crawl space encapsulation worth the cost?

In short, crawl space encapsulation is worth the cost.

When you don't have a properly encapsulated crawl space, you may notice a variety of issues, including sinking floors, pest infestations, mold growth in the crawl space, and poor indoor air quality in your entire home. These issues can wind up being more expensive to fix than it is to have your crawl space encapsulated in the first place.

It is particularly important to encapsulate your crawl space if you live in an area where the water table is higher or if you live in a humid climate.

What is the difference between a vapor barrier and encapsulation?

The difference between a vapor barrier and crawl space encapsulation is that encapsulation includes a dehumidifier while a vapor barrier does not. Crawl space encapsulation describes a whole system that is designed to keep your crawl space clean and dry. Encapsulation keeps water out and prevents water vapor from seeping into the crawl space from the ground up.

What is our crawl space encapsulation process?

The CleanSpace® Crawl Space Encapsulation System addresses each of the main threats to your crawl space: outside air, excess moisture, water, mold, and pests. A dry, clean crawl space means a healthier, more comfortable home overall.

1. Stop Water Intrusion

Before encapsulating your crawl space, it's important to take care of any water intrusion issues, including plumbing leaks, foundation leaks, and drainage problems to prevent water damage and keep your crawl space dry. Clean CrawlSpace Inc. can help stop water from coming into your crawl space by installing a perimeter drainage system and sump pump designed specifically for the crawl space.

2. Prevent Moisture Seepage

Moisture enters your crawl space through the ground and foundation walls. Adding a vapor barrier in your crawl space helps prevent mold growth, wood rot, and pest infestations.

We cover the crawl space floor and walls with the heavy-duty CleanSpace® vapor barrier. CleanSpace is a 20-mil reinforced polymer liner that's offered with a 25-year warranty against rips and tears. When installed as part of a complete crawl space encapsulation system, CleanSpace provides a dry, healthy crawl space that can be safely used for storage.

3. Seal Air Leaks

Research shows that crawl space vents let in humid outside air that raises the relative humidity in the crawl space. A damp crawl space is the ideal environment for mold and pests. Adding crawl space vent covers will help keep your crawl space dry and pest-free. CleanSpace® vent covers are insulated, will never rot or need paint, and provide an airtight seal against unconditioned outside air.

During your crawl space encapsulation project, we will also seal the rim joist and all penetrations to the outside, such as around pipes and electrical wires.

4. Condition the Air

We offer crawl space dehumidifiers to deal with the air in your crawl space. Installing a crawl space dehumidifier is the best way to control the humidity level in your crawl space. The SaniDry Sedona dehumidifier is designed specifically for basements and crawl spaces.
