MOISTURE Control Services
There are many different ways moisture can enter a crawl space.
- Wicking through the concrete block foundation.
- Surface runoff into the crawl space.
- Subterranean spring.
- Humid air entering through foundation vents.
- Leaking pipes.
- Leaking roof or siding.
- Soil moisture vapor from crawl space floor.
Most homes in the SE United States have inadequate ventilation, so any moisture that enters the crawl space will have a difficult time exiting.
- In crawl spaces, wet fiberglass insulation does more harm than good. Insulation retains moisture and then holds it against the wood. It also prevents air flow that would dry it out. This long-term exposure to moisture will cause wood decay fungus and/or mold.
Once the insulation is wet, it becomes heavy and begins to separate and fall to the ground. Even when it remains in its position, once wet it no longer acts as an insulator. The R-value drops from R-19 to an R-2.
- When humid air enters the crawl space due to a lack of cross ventilation, it condenses on the cool HVAC duct system and then “rains” in the crawl space, further elevating the moisture level.
Many times, water can find its way into a crawl space and may never dry out. Due to the dark environment and inadequate ventilation, it can stay forever, and build over time. The high moisture levels can and will lead to damage to the wood structures.
It is impossible to stop water flow! However, it can be controlled, blocked and redirected.
Possible Solutions:
- In some cases, a standard 6-mil vapor barrier is sufficient to reduce the moisture level.
- In other cases, additional ventilation or forced air ventilation may be the answer.
- In more severe cases, a dehumidifier may be needed.
- When wet, damaged insulation is present. It is no longer effective and will need to be removed and hauled away.
- In some instances, the outside grade may need to be altered to prevent runoff from entering the crawl space.
Any standing water can be ejected using a sump pump installed at the lowest point in the crawl space.
Many times, one or more of these services can solve the issue. However, in some cases it is necessary to encapsulate a crawl space to completely solve the problem.
My father, Billy Gardner (Our company founder) told me long ago, "Treat your customers fairly, serve them well and show them respect and they will never consider using another company." That simple philosophy has proven to be true, over the last 54 years.
To be able to compete with large international, billion dollar corporations and win, we can't be merely as good, we must be better than they are. We have to be punctual, treat our customers with respect and do a great job every time!
