Crawl Space Vapor & Moisture Barrier

Some people call them vapor barriers and others call them moisture barriers, but they are one and the same and they are needed for the same reasons. So, how do vapor and moisture barriers work? Do you need one? The easy answer is to call our company and schedule a free crawl space inspection to determine if a vapor and moisture barrier is right for you.

Homes that are built over a crawlspace often suffer from moisture-related issues because of the crawlspace’s surroundings. Naturally, when moisture mixes with wood, it creates a recipe for mold and other problems, such as termite infestation, which often lead to the deterioration of a home. Because indoor airflow naturally rises, using a vapor and moisture barrier and dehumidifier together in the crawl space – installed by a professional company – can dramatically decrease the amount of moisture and soil gas present.

Crawl space vapor and moisture barriers can greatly reduce the risk for:

1. Mold
2. Mildew
3. Wood rot
4. Floor failure
5. Decreased insulation R-values
6. Increased heating & cooling bills
7. Odors
8. Insects
9. Dust mites
10. Aggravated allergies
11. Poor storage environment
12. Poor indoor air quality (IAQ)

Without a barrier installed by a professional company, moisture – as well as water vapor – can permeate the crawl space through the earth around your home from any number of plumbing issues or through moisture entering the crawl space vents. The result is a transformation from a crawl space to an actual breeding ground for mice, rats, snakes, and other creatures that can thrive in this damp, dark habitat. In addition, as warm air rises through your home and leaves through the upper levels, crawl space air is pulled up into your home with it. As the warm air rises, there is nothing to stop the humidity, mold spores, dust mite waste, and odors coming up with it – unless you hire Eco Pest Control, the leading crawl space vapor and moisture barrier company in the greater Richmond, Newport News, and Williamsburg areas.

Insulating a crawlspace that is vented is a sticky situation. Insulation will not keep humid summer air or cold winter air away from a structure’s floorboards. Most standard insulation vapor barriers installed in crawl spaces by building contractor companies will allow moisture and mold to soak through the material, weighing it down and causing it to crumple onto the floor. As you might guess, that is not good for your home.

Some contractors usually lay down a very thin, non-fire-retardant 4-mil or 6-mil plastic liner that does little good, because air can still enter from crawl space doors, vents, pipes, or other permeable openings. You need a 15-mil liner, which is even more reason to ensure your crawl space vapor and moisture barrier is installed by a company that specializes in this service.

Furthermore, most standard vapor and moisture barriers will either be attached by a seal tape or be stapled to the wall. The problem with these methods is that it not only defeats the purpose of the liner by injecting holes into it, but also creates a rumpled-looking effect in the crawl space. Using an adhesive liner – a technique generally offered only by companies that specialize in the installation of vapor and moisture barriers – ensures longevity; you will also appreciate the cleaner and tidier look. The vapor barrier must cover all areas, including the foundation walls and piers.

If you want the best solution for your problem, then the answer is yes. The bottom line is that a durable, 100% reinforced 15-mil vapor and moisture barrier that is waterproof, anti-microbial, fire-retardant, and puncture resistant – and installed using an adhesive strip – can transform a moist, unhealthy crawl space into a clean, sanitary environment that no longer promotes mold, odors, pests, and even potential infestation. You can rest assured that the crawl space can even be used for storage purposes and ultimately fulfill its purpose of promoting healthy air circulation and reducing overall humidity in the house.
