Mold grows when the humidity level stays around 60%. The goal is to reduce that humidity level to 30-40%. However, a moisture barrier can be combined with a sump pump to reduce standing water and humidity. Think of how water droplets form on a glass of iced tea in the summer.It's important to note that a moisture barrier is ineffective against problems with standing water.Also, differences in temperature cause condensation.

Clear plastic lets you see how the barrier is functioning and detect termites or other problems. Your home especially needs one if the home inspector finds signs that water intrusion is a chronic problem or has mold appearing on several wooden structures. No one wants any of that.For the long term health of your home and those who live there, add a moisture barrier to the crawlspace. That's because detection and prevention of mold in a home presents challenges for everyone. Moisture comes in, rather than going out as it was meant to. Mold causes various health problems and its ongoing presence could even lead to lawsuits.Your home inspector dreads seeing mold in your home just as much as you do. It reduces the relative humidity in the crawlspace, and that reduces the potential for organic growths like molds and rot. It's not necessary to fasten or anchor the plastic with rocks or gravel, since there shouldn't be any breezes or foot traffic to move the plastic.

The moisture barrier collects those water droplets that would otherwise form on wood or concrete. Water droplets form on surfaces, such as concrete or wood.. Unfortunately, the outside air is often too moist to let the crawlspace dry out.When it comes to mold, your home's crawlspace is one of the worst offenders, but there's a simple, relatively inexpensive solution known as a moisture barrier to keep that space dry that can make a big difference. This will cut down on mold growth.First, it's important to understand that there has extrusion blow mold Factory to be a certain amount of ventilation around the foundation of a home to allow moisture to evaporate.

As a result, the condensation problem is minimized, and the humidity level stays lower.Believe it or not, the moisture barrier is nothing more than plastic sheeting laid over 100% of the crawlspace floor. Condensation in the crawlspace can be prevented by sealing it out with a moisture barrier, sometimes called a vapor barrier. When enough moisture collects on surfaces such as wood, mold readily grows as a result.Ideally every crawlspace should have a moisture barrier. It's only good at keeping water vapor from coming up through the ground and condensing on crawlspace surfaces. Water collects on the underside of the barrier and will go back into the soil.

Here's how a moisture barrier works. The concept may not sound logical at first, but you'll soon see how it makes sense. Plastic should be at least 6 mils thick to last over time, and sections should overlap by a foot. It's amazing what a difference a simple solution can make. Water vapor from the ground evaporates, causing the humidity level in the crawlspace to go up. There should be no gaps
