Moisture has been wreaking havoc in this crawl space. Mold and mildew are growing on the floor joists and the insulation has fallen and is damaged from the moisture. Efflorescence and staining on the foundation walls tell us that moisture is not only entering through the open vents but also through the block walls.
The homeowner wants to seal and insulate the crawl space to prevent future moisture damage and microbial growth. We began by treating the mold and mildew growth with shockwave, and antimicrobial that kills the microbial growth. Then we set to cleaning the space out then sealing all vents, penetrations to outside through the foundation walls, and the sill plate. CleanSpace Vapor barrier is installed, wrapped and sealed around all piers, attached to the foundation walls, and sealed at all seams. Finally, the rim band is insulated and foam board insulation is installed on the foundation walls and sealed at all seams. A dehumidifier is installed to control the relative humidity and help prevent future microbial growth.
We installed dense packed cellulose insulation in the attic rafters of a Hampton, VA home. As you can see, the attic was completely bare before our insulation was added. If the attic is left like this, the home can become extremely uncomfortable. It makes the adjacent rooms ridiculously hot in the summer, wasting the conditioned air seeping through the cracks. The energy bill can become way more expensive than it should be. By insulating this home, we have created a barrier so the homeowners can save on their energy bill in the long run.
This homeowner had concerns about water entering their crawl space. At our inspection one of the concerns, we found that the existing vapor barrier was not sealed, allowing moisture in. As part of the solution, we installed a 20mil Heavy-duty, Vapor Barrier with UltraFresh Antimicrobial built-in, called CleanSpace. We ran it up the walls sealing it and leaving a 2" viewing strip for a termite inspection and sealed and wrapped all the piers.
This Lancaster, VA homeowner has several improvements happening in their crawl space. Installing a new CleanSpace Vapor Barrier (aka moisture barrier or crawl space liner) is just one piece of that, but a very importiant one.
This 7 ply, poly string-reinforced vapor barrier is combined with a 4-inch wide liner tape that seals the crawl space off from the earth's moisture. The product is durable enough to withstand servicepersons crawling around in your crawl space without worry of it becoming detached or torn.
This Williamsburg, VA homeowner opted to have their attic insulated from the rafters with closed cell spray foam insulation. This solution is ideal for attics that house HVAC equipment, are used for storage, or that the homeowner would like to convert to a finished space. Insulating from the rafters extends the thermal barrier of the home and helps control attic temperatures.
