Crawl Space Repair Photo Album: Great Falls VA Crawl Space - Humidity Reduction

This Great Falls VA homeowner was experience a number of comfort issues living in their home, one of which was excessive humidity in the living spaces of the home. The floors on their main level were often cold in the winter and the air quality inside the home wasn't what they wanted it to be. After calling us to have a free Home Performance inspection done by our Sale Pro Eric, it was found that most of the problem was originating from the crawl space, which was unconditioned with outside air coming in, cold and wet, dirt floors as well as failed insulation falling loose from the ceiling of the crawl space. Our Production Team removed the old insulation and then covered the dirt floors before insulating the walls, air sealing the insulation panels and using spray foam to close up the rim joists which were allowing air to come in. This resulted in a conditioned space, unimpacted by outside air and temperatures. It also eliminated the moisture and poor quality air in the crawl space from moving into the living spaces above.

Crawl Space Before

An open air vent in the wall was allowing external air and moisture into the crawl space. The dirt floors allowed moisture to settle and make the space humid.

Crawl Space Before

The cinder block foundation walls were uninsulated, allowing the cold temperatures outside to be transferred into the crawl space. This cold would make the floors above cold as well.

Pipes Exposed to Cold

The HVAC ducts and plumbing pipes were all passing through space that was the same temperature as outside. this could lead to freezing water pipes.

Bad Crawl Space Insulation

The old insulation intended to insulate the ceiling of the crawl space and keep the floors above warm was not work due to having fallen loose. This would later be removed and insulation would be installed on the walls rather than the ceiling.

Crawl Space Floor Covering

Drainage mating laid over the dirt floor to contain moisture and then Terra Block on top of that would help to insulate the floors and keep the air above cleaner and less humid.

Work In Progress

With Terra Block covering the floors and the old insulation removed from the crawl space ceiling, the area is now ready to be covered with Clean Space material to seal it all up.

Silver Glo Insulation Panels and Clean Space

Insulation panels, air sealed with Zyp Foam now cover the walls, protecting the crawl space from external air and temperatures. Clean Space covers the flooring and the base of the insulated walls.

Full Crawl Space Encapsulation

Insulation panels, air sealed with Zyp Foam now cover the walls, protecting the crawl space from external air and temperatures. Clean Space covers the flooring and the base of the insulated walls. This space in now able to be used for storage if needed.

Crawl Space Insulation

Silver Glo panel insulation covers the walls with Spray Foam having been used to seal up the rim joists at the top. This will keep external air outside of the crawl space.
