Crawl Space Repair Before & After Photos

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 crawl space in Lancaster was suffering from many outside moisture issues. One of these issues was that the old liner covering the dirt floor was torn in many places, allowing the earth's moisture to rise and affect the relative humidity of the crawl space. An excessive moisture content can lead to condensation, material damage, and even mold or mildew growth. Our installers removed the existing vapor barrier and any debris from the crawl space, then placed a 20-mil vapor barrier, called CleanSpace, over the dirt floor of the crawl space. This heavy-duty liner covers the entire crawl space floor, gets wrapped around all piers, and mechanically fastened to the foundation wall, six to eight inches above outside grade. The CleanSpace will help protect the crawl space from any moisture rising from the earth, and it allows service personnel to maneuver freely throughout the crawl space. This solution is one of many to help encapsulate and seal off any outside influence. If you are interested in our vapor barrier, then please give us a call today to schedule your free estimate.

The old vapor barrier in this crawl space was not effective. It was loose and unfastened to the walls or wrapped around piers and did not protect the crawl space from the earth's moisture. The vapor barrier was replaced with the CleanSpace Encapsulation System. CleanSpace is a 20mil vapor barrier with UltraFresh antimicrobial built-in. It is durable for service persons to crawl on without worry of tearing. CleanSpace is wrapped around and sealed to all piers and sealed to the crawl space walls 6-8 inches above outside grade. 

This home had water seeping into its crawl space. The high humidity and warm temperatures in our area result in microbial growth on joists, falling insulation, cold floors, and poor indoor air quality in many crawl spaces and homes. To repair this crawl space, we cleaned it out, treated the joists with an antimicrobial, installed a drainage system and sump pump, laid down and sealed a 20mil vapor barrier to the walls, piers, and floor, and insulated the walls with spray foam. 

Efflorescence on the walls and moisture stains on the block indicates that moisture has been working its way into this crawl space through the cinderblock foundation. 

As part of the encapsulation, Foamax foam board insulation has been installed on the walls of this crawl space creating a continuous R-10 of insulation on the foundation walls. A 2-inch viewing strip has been left at the top of the foundation wall per VA building code for termite inspections. The foam board is mechanically fastened to the wall and sealed at seams with foam.
