Many crawl spaces have moisture problems. A vented crawl space that has a dirt floor is certain to be a damp environment where mold, mildew and even wood rot can easily take hold.
Even a crawl space with a concrete slab floor can be excessively damp.
Drying out this damp environment is a smart move, for your home’s value and for family health as well.
Effective crawl space dehumidification can keep your crawl space dry enough to discourage mold growth and keep moisture-loving dust mites away.
The dehumidifier is designed to handle the tough moisture conditions in a crawl space. This photo shows a model that drains directly into a crawl space sump pump.
Building scientists (the experts who test and study how buildings perform under different conditions) recommend following two strategies to control crawl space moisture. First, the crawl space should be sealed or “encapsulated” to isolate the space from moisture in the soil and exterior air. The encapsulation process is completed using heavy-duty moisture barriers and covers for the crawl space access door and vent openings.
Sometimes the encapsulation process also needs to include a waterproofing system to prevent water from leaking into the space. Secondly, a crawl space dehumidifier is installed, if necessary, to dry out the air in the crawl space and maintain low humidity levels. The crawl space dehumidifier can drain into a crawl space sump pump (if there is one) or directly to the exterior.
For homes in colder climates, it’s often advisable to integrate crawl space insulation with the encapsulation process. Installing special rigid foam insulation against crawl space walls keeps the crawl space warmer in wintertime, limiting condensation (and moisture accumulation) on cool surfaces. The added benefit of crawl space insulation is that the home becomes more comfortable and more energy efficient.
Most standard crawl space products available from retail outlets and home centers are not appropriate for use in a crawl space. The dehumidifier is designed to provide many years of energy-efficient, trouble-free performance, even in tough crawl space conditions. It drains automatically, so there is no reservoir to empty. Our dehumidifier meets stringent requirements for energy efficiency, and its precisely calibrated controls allow you to dial in the desired humidity level.
It’s not always easy to remove humidity from your crawl space. What are the most important things to know about dehumidifying your crawl space?
How Common Is Crawl Space Moisture?
People often wonder whether crawl space moisture is just “normal.” It’s true that it’s very common for people to leave their crawl spaces completely untouched, resulting in musty, moldy, and damp crawl spaces, but that doesn’t mean it’s normal. It just means that it’s a common problem more homeowners should address.
Is Crawl Space Moisture Really a Problem?
There are many problems that crawl space moisture can cause. For example, if you have an area of high moisture, you can also end up with mold and mildew, either in the crawl space or in the rest of your home. Crawl space moisture can also cause warping and shifting, both of which are bad for your crawl space.
What Are the Best Ways to Dehumidify a Crawl Space?
Crawl space dehumidification can be a long process. Of course, a crawl space dehumidifier can help you avoid humidity, but you should only use it in conjunction with other processes, like crawl space encapsulation. It’s best if you approach crawl space dehumidification with the long term in mind, not just the short term.
How Can I Start with the Dehumidification Process?
Starting the process of crawl space dehumidifying can be a little daunting. After all, there are a variety of steps you may need to follow.
