Cost-Effective Ways to Implement a Crawl Space Vapor Barrier

The most effective way to reduce moisture buildup in crawl spaces or “caves” is to install a vapor barrier along the walls and ceiling. The CrawlSeal Crawl Space Moisture Barrier system is fast and easily attached to the wall with plastic stakes. Installing a crawl space moisture barrier is often one of the best ways to revitalize your home and avoid the need for additional crawl space repairs in the future. Installing the vapor barrier is not a do-it-yourself project, but if you have the proper tools, the job is easy enough to do by yourself.

crawl spaces are moisture-filled rooms that are below ground level. Most homes have at least one such space and many more throughout the house. These moist spaces can be comprised of basements, attics, crawlspaces, and laundry rooms. Moisture penetration into crawl spaces is a leading cause of mold and mildew problems, as well as allergic reactions, asthma, and damage to the respiratory system. Allowing humidity to remain high in these areas can result in health problems for family members living in the home.

Some homeowners believe that the only way to effectively protect their homes from penetration of moisture is to have structural drywall installed. Unfortunately, this approach does not work in all spaces. Basements, attics, crawl spaces and laundry rooms that are below ground level may not be effectively protected by drywall alone. There are other options available for water damage protection in these spaces, including crawl space moisture barriers.

The most effective crawl space moisture barrier system has two parts. The first part consists of an air gap, which is an area where air can flow. This allows any moisture to escape without being trapped or blown out. A second part of this system is an impermeable membrane. This membrane can be installed on the interior or exterior walls and performs the same function as the air gap.

When moisture penetrates the exterior wall, it can create a layout. A dryout will not affect the inside of your home, but it will affect the outside. During a dryout, the moisture will drip or seep into the walls, and may cause mold or mildew to grow. A continuous wet environment can also promote the growth of mildew and mold. A crawl space water barrier prevents these conditions from occurring. The following is a common occurrence that can indicate a need for a new crawl space moisture barrier:

Any spaces in your house that are lower than floor level should have foundations that are reinforced. Cracks, openings and misalignments in the foundation can allow water to get in while the house is sitting empty or during times when there are no trains. Cracks in the foundation, especially at corners, will allow cold air to get in, causing a heating loss. This will lead to more leaks and more humidity, which increase the chance of mold or mildew growing.

Any spaces that connect rooms will often become moist due to floor heat. If this is the case in your home, then you might want to consider adding a crawl space moisture barrier to all of these connecting areas. A small moisture barrier will likely do the trick to prevent the formation of mildew or mold, because mold needs moisture to grow. When this happens, you will have leaks and you will have water damage.

There are numerous cost-effective ways that you can implement a new crawl space moisture barrier, but they all have the same goal in mind: prevention. By putting up a barrier that prevents water from reaching your walls, you will prevent future mold and mildew problems from occurring. When you are ready to invest in such an investment, you can shop around for the best price and get it installed by a professional. This is also one of the smartest ways to make sure that you are protecting your most valuable asset, your family, and saving yourself money in the long run.
