Crawl Space Repair Before & After Photos

The existing 6-mil vapor barrier in the crawl space does not fully cover the ground and is allowing moisture from the earth to rise into the crawl space. This is a concern because it raises the relative humidity (RH). When the RH is above 60% and there are warm temperatures, mold and mildew can begin to grow on the organic materials under the home including the wood floor joists. 

As part of an encapsulation system, we installed a 20-mil vapor barrier called CleanSpace. The heavy-duty vapor barrier is attached to the crawl space walls 6-8 inches above outside grade, wrapped around all piers, and sealed at all seams, sealing the crawl space off from the earth's moisture. CleanSpace is more durable than the previously installed 6-mil, which is about as thick as a trash bag, withstanding service persons crawling and working in the space. 

Open vents allow the outside into your crawl space. In the winter cold air is pouring into the crawl space, and in the summer hot and humid air floods in. The disheveled and damaged 6-mil vapor barrier has been allowing moisture from the earth to rise into the crawl space. Staining and efflorescence on the foundation walls indicate that moisture has been traveling through the porous cinderblock. The excess moisture in the crawl space has allowed mold to begin to grow on the floor joists. 

As part of the encapsulation system, we installed CleanSpace Vapor Barrier sealing the crawl space off from the earth's moisture. We sealed all vents and insulated the crawl space walls with a continuous R-10 of rigid foam insulation. Preventing outside moisture from entering the crawl space is a big step in controlling the environment. We also installed a dehumidifier to help control the relative humidity in the space and prevent future mold and mildew growth. 

This Seaford crawl space had water running through it, after the installation of a drainage system, the crawl space was encapsulated with Spray Foam Insulation. 

This crawl space had standing water, mold, a damaged vapor barrier and falling insulation. Our team encapsulated the space with a new vapor barrier, we added spray foam insulation where necessary and installed a dehumidifier and sump pump. Now this crawl space is sure to be mold and water-free!

The exterior access to this crawl space was in good shape. However, it was uninsulated and it was not air tight. This means it allowed heat to radiate in and warm humid air to flow into the crawl space. We installed an interior friction fit door behind the access door. The interior door provides an R-10 of insulation and air seals behind the crawl space access. This seals a big hole that adversely impacts the crawl space otherwise.
