Crawl Space Solutions
The vast majority of homes built on crawl space foundations suffer from poor moisture management. Some of the common symptoms of a crawl space moisture problem are:
- Mold or moisture damage in the crawl space or living area
- Musty odors in the living area
- Condensation (“sweating”) on air conditioning ductwork or equipment
- Condensation on insulation, water pipes or truss plates in the crawl space
- Buckled hardwood floors
- High humidity in the living area
- Insect infestations
- Rot in wooden framing members
Prior to discussing these avenues for moisture entry into the crawl space, let’s look at how things dry, their dew point temperature, and mold.
The key component to water restoration is to understand the principles of drying. Water, as a vapor, always moves from a high concentration to a low concentration. For example, if we look at a wet towel on a rack, the moisture will move from the towel to the air around it because the air has a lower moisture concentration than the towel. The moisture in the towel eventually reaches equilibrium with the moisture in the air and would be considered “dry”. That same towel “dries” slower when the air is humid (or contains more moisture) than it would if the air was drier. Temperature also plays a part in drying, but that is for a later discussion.
Dew point temperature is also a key point in understanding moisture and mold. The dew point is the temperature at which the air can no longer hold any more moisture (becomes saturated) and water (dew) forms on a surface. The colder the surface is below the dew point temperature, the more water forms on that surface.
Simply speaking, mold only needs two things to grow: food and water. Mold spore (seed) is on every surface in the world and it virtually always has a food source (organic matter). Even on non-organic surfaces like glass or metal, there is a thin layer of organic matter which we call “bio-film”. The last component that is needed for the mold to start growing is water!
Moisture primarily enters the crawl space from three areas: the ground, the foundation, and vents.
Ground: The ground always contains moisture. When it rains the ground is wet and that moisture migrates to the ground under your home. This moisture in the ground under your home then “dries” to the air in your crawl space. This increased level of moisture in the air of your crawl space then condenses on the wood structure if the dew point temperature is reached. This condensed water is the last component that the mold spore (seed) needs to begin growing.
Foundation: Likewise, when it rains, your foundation absorbs the moisture from the ground. As the foundation moisture concentration builds, it too begins to “dry” to the air of the crawl space. Should the crawl space air come in contact with a surface that has a temperature that is below the dew point temperature of the air, then condensation occurs, allowing mold to grow.
Ventilation: For many decades, building codes and conventional wisdom have prescribed ventilation with outside air as the primary method of moisture control in crawl spaces, known as an “open” system; however, ventilation with outside air only makes moisture problems worse, allowing outside humid air to enter the cooler crawl space where it reaches its dew point and condenses.
Through building science and research, we understand why crawl space ventilation fails and why a “closed” crawl space system, with NO vents to the outside, can provide greatly improved moisture control and significant energy savings when properly installed.
The following “A Quick Reference: Moisture Mitigation Systems” is the solution to moisture in a crawl space. This reference lists the basic design considerations and information generated by research projects, diagnostic investigations, and collaboration with a variety of building science professionals and consultants across the country.
Trauma Scene Cleanup/Bio Recovery
Certified Restoration, Ltd. offers bio recovery cleanup. Federal and state agencies regulate the handling and disposal of blood and other bodily fluids, so it is important not to minimize the hazards associated with bio recovery and what is required to restore the property to a healthy environment. Certified Restoration’s ABRA (American Bio Recovery Association) certified technicians are prepared to handle small blood-stained carpets to large homicide, suicide, and decomposition scenes.
Poor indoor air quality and some health issues may be related to irritants found inside your home or business’s HVAC system. Our trained professionals will clean your entire HVAC system, eliminating common contaminates like pet dander, pollen, insects, and even rodent feces. Those who suffer from asthma or allergies can breathe easier knowing their duct work and furnace have been properly cleaned by Certified Restoration, Ltd.
Building a new home is relatively easy for an experienced contractor. Understanding how to repair/rebuild a property that has been damaged by wind, fire or water is a different process all together. Our team of experienced reconstruction professionals understands the way building components are assembled, and work hand-in-hand with property owners and their insurance companies to return their properties to a pre-loss condition.
