Frequently Asked Questions

The short answer is… probably yes. If you have water that is seeping in from around your foundation walls or up from the ground because of hydrostatic pressure, then absolutely yes! In fact, a sump pump alone will not take care of the water. You also need a complete drainage system installed along the inside perimeter of your foundation walls. Some grading of the dirt under your home will also need to be done. If the water is not remedied correctly, then it will be able to stand and flow freely throughout your crawlspace. Water will pool and stand in the low areas of your home if a proper drainage system is not installed. Pooling and standing water can cause your foundation piers to sink or lean, which will cause structural damage. Mildew and wood rot will grow due to the excessive moisture which is due to the water.

No. They are two different problems and how you deal with each of them is completely different. Water problems typically are caused by water seeping in from around the foundation walls in the crawlspace. A water problem requires a complete drainage system along the inside perimeter of the crawlspace and a proper sump pump to be installed. Moisture problems can be caused by water seepage, but they can also be caused by plumbing leaks in the crawlspace, condensation from your HVAC and sweating ductwork under your home, your foundation vents letting humid air under your home, fiberglass insulation under the subfloor in your crawlspace staying wet or damp. There are many different things that can moisture issues in your crawlspace. The only permanent solution for dealing with moisture in your crawlspace is our Doctor’s Choice Encapsulation System.

1000% YES! A true encapsulation system should include a dehumidifier. It should not be an option. When a crawlspace is encapsulated properly using the right products, it still is not 100% airtight. The encapsulation will seal off your crawlspace from the dirt ground and the outside humid air, but it doesn’t dry out the crawlspace by itself. A proper dehumidifier is necessary to dry out the wood and the contents in your crawlspace. A dehumidifier will filter out mold spores and keep your crawlspace dry regardless of how high the humidity is outside. To prevent mildew and moisture, the relative humidity needs to be less than 50% and that can only be achieved and maintained with the help of a proper dehumidifier.

It depends on what you are wanting to achieve for your crawlspace. If you are wanting to completely dry out your crawlspace, treat for and prevent mildew and wood rot, eliminate odors and smells, prevent moisture, high humidity, and condensation, have cleaner, breathable air in your living space, and an overall healthier home, then you need our Doctor’s Choice Encapsulation System. If you are not having any of these issues and want to have something cleaner to crawl on in your crawlspace, then a simple plastic barrier on the ground will be sufficient.

It’s a 100-year-old idea. Starting many years ago, when crawlspaces were built, builders believed you should keep the vents open in the summer and close them in the winter. You closed them in the winter to keep the cold air out and opened them in the summer so you could air out the crawlspace and keep it dry. This theory works in certain parts of the country. However, in the south, this theory is completely wrong! Over the past 25 years, there have been numerous studies done. There is now a Crawlspace Science. The building industry has changed its recommendations for building crawlspaces in the south.

They have realized that you don’t want outside airflow under your home in a humid climate. In Arkansas, for 8-9 months out of the year, we have a lot of humidity and moisture in our air. When your foundation vents are open, it’s that humid air that is blowing under your home. Over time, mildew will form and even wood rot (wood decay fungus). Once wood rot is growing, you will have significant structural damage. Once the mildew increases, this can cause significant health issues for you and your family. Once you apply science, it just makes sense.
