Vigilant homeowners can also inspect their building for telltale signs of crawl space moisture.

If you have any of the aforementioned home characteristics that make your property susceptible to crawl space moisture intrusion, it’s a good idea to connect with a professional contractor to start discussing your crawl space insulation. Lastly, climates that are particularly humid are also more susceptible to crawl space moisture intrusion. Unfortunately, this ventilation tend to be problematic, allowing moisture located beneath the home to remain trapped there. Older homes are also more likely to require crawl space vapor barrier insulation because they tend to have small openings for ventilation built into the crawl spaces to facilitate easy access of air. Homes that reside atop exposed dirt crawl spaces are often in need of crawl space insulation since this situation makes it very easy for water to seep into the home. When it comes to determining if your home needs a crawl space vapor barrier, there are several factors that could make your property in need of moisture insulation. The less permeable material is, the lower the perm rating will be. Another term to be familiar with when it comes to vapor barriers is “perm.” The perm rate is used to represent the likelihood of water vapor passing through materials. Each mil is the equivalent of 0.001 inches of thickness, with 6 mils of reinforced poly often being recommended for the standard crawl space insulation project. Crawl space vapor barriers are a minimum of 6 mil and a maximum of 20 mil in thickness, with the latter offering the most fortified and heavy-duty protection. Teaming up with a trained contractor will help you determine which vapor barrier thickness is best for your project. On the other hand, reinforced ploy sheeting offers a variety of different thicknesses for a range of strengths that can match your project’s needs. Poly sheeting is preferred because it offers the dual benefit of durability and value, making it ideal for providing vapor barriers for many cases of water intrusion that are operating within a budget. The most commonly used vapor barrier is reinforced polyethylene plastic sheeting, or poly for short.
A pest control specialist is recommended to provide a plan to resolve the current infestation and prevent future pest infestations.Rodent feces, urine, and other associated debris may harbor bacteria, parasites, and odors. Evidence of past or present rodent infestation was noted, contaminating the insulation and vapor barrier, requiring removal and replacement.Current ventilation is adequate to exhaust normal amounts of humidity.Contaminated – Vapor barrier shows evidence of past flooding or is extremely soiled.Damaged – Vapor barrier damaged and missing in areas, allowing excessive moisture transfer from damp soil into crawlspace framing.
