Crawl Space Encapsulation

For Contractors, Builders, And Homeowners

The crawl space is one of those “out of sight, out of mind” areas of the home, but an unencapsulated crawl space can affect home comfort, safety, and performance. Threats include: intrusions of outside air and water or moisture, radon gas infiltration from exposed ground, mold, and pests.

Crawl space encapsulation helps protect homes from these threats and improve indoor air quality by creating an impenetrable barrier between the ground and the home.

The RVI Process

  • Remove debris
  • Grade floor
  • 100% coverage of the ground with a vapor barrier
  • Seal seams and penetrations of the vapor barrier
  • Air seal and insulate foundation walls and rim joists

// The Benefits of Crawl Space Encapsulation

Crawl space encapsulation of Wisconsin homes and cabins turns an open, exposed environment into a controlled environment. RVI’s crawl space encapsulation contractors utilize the latest building science research and techniques to create safer, healthier, and more comfortable homes.

After crawl space encapsulation, you can expect:

  • Better air quality throughout the living space.
  • Energy efficiency improvements; some studies indicate a 20% reduction in energy costs after crawl space encapsulation.
  • Fewer pest and critter problems.
  • Improved durability of flooring, HVAC equipment, and other components in the crawl space.
  • Greater home comfort due to improved temperature balance.


I would recommend these folks to everybody

Sam and his crew did a terrific job of cleaning out 45 years of debris from our “rathole” of a crawlspace and turning it into what I now refer to as our “surgical suite”. The space is now totally dry, level, insulated and sealed. We could eat off the new plastic floor which covers our old sand base. I now even look forward to going down into what I used to refer as my personal pit from hell. It’s totally dry, clean and habitable. Sam even said that he would take care of any problems that might arise for the indefinite future. I would recommend these folks to everybody. Thanks from a totally satisfied homeowner.

I feel the cabin is dryer and more comfortable!

Sam did a good job for us. He stayed within the original quote, which we appreciated! He completed the work as he said in the timeline he gave us. And most of all, even though our work is “under the cabin and out of sight”, Doug and I feel the cabin is dryer and more comfortable! We also appreciated the finished pictures he sent and his communication with us was very helpful as we live nearly 7 hours away from the cabin!
