Mold & Moisture

Mold is not only unsightly, it can also cause structural damage, allergic reactions and respiratory problems. Clark’s is certified and insured as a mold remediation company, and all our work meets EPA and OSHA guidelines.

Protect Your Home & Your Health

Mold spores play a significant role in nature by breaking down dead organic matter, like the fallen tree in the woods. However, these same spores, left unchecked in your home environment, can lead to significant damage and/or health concerns.

Not all people react the same when they come in contact with mold. However, mold has the potential to cause health problems, especially in people with immune deficiencies or those with respiratory conditions. Also at risk are infants, children and the elderly.

What is the difference between mold and fungi?

Fungus is a microscopic substance that exists in the air around us all the time. It is neither plant nor animal, nor a type of bacteria – it's a separate type of living organism that occupies its own kingdom of classification.

Mold is one type of fungus. There are hundreds of thousands of species of fungi. The only way you can be 100% sure a certain fungus is indeed "Mold" is by having it tested to confirm that it is a mold.

How moisture levels affect growth

  Surface fungi can grow on the wood of the floor system in a crawlspace if the wood moisture content is 20% or greater.
  Wood-destroying fungi will occur if the moisture content is 28% or greater.
  If the moisture levels are below 20% but surface fungal growth is present, it is considered "Inactive."
  If the moisture levels are below 28% but wood-destroying fungi are present, it is considered "Inactive."

Crawlspace Systems

Moisture control in your crawlspace is the key to preventing mold and wood-destroying fungi. We feature the ATMOX Crawlspace Ventilation System as an economical and effective alternative to Encapsulation.

ATMOX uses a combination of fans installed in the crawlspace vents and dehumidifiers. A controller is installed that measures wood moisture content, crawlspace humidity and outside humidity, and determines when air from the outside should be circulated through the crawlspace, or the crawlspace should be closed off and the dehumidifier used. A control is mounted in a convenient location so you can monitor the status of your crawlspace at any time.

For Your Information

Homes used to be relatively simple in their design: rectangular in shape, with nothing to block air flow through the crawlspace. Crawlspace vents were spaced so many feet apart on all sides so that air could flow through and somewhat effectively help control moisture.

But today’s homes are increasingly more complex with large garages, multiple garages, large porches on many sides and limited space to install vents. This creates large pockets of dead air in the crawlspace. The ATMOX system includes fans designed to hang from the floor joists and circulate the once-dead air so that it can be processed by the dehumidifier or replaced with acceptable outside air.

Controlled ventilation for the entire crawlspace! Our ATMOX Crawlspace Ventilation System uses a series of intake and exhaust fans strategically placed in select crawlspace vents to ensure air circulates through the entire crawlspace.

Vents that do not require fans are closed off. Sensors measuring dew points inside and outside the crawlspace feed the controller information where it determines whether to exchange air, dehumidify or simply keep the status quo. It’s a smart system that’s simple to operate.

Vapor barriers, drains, sump pump service in South Carolina

Barriers, Drains & Pumps

All homes with crawlspaces should have a vapor barrier because the ground contains moisture, and that water naturally evaporates from the soil.

A vapor barrier prevents the moisture in the ground from escaping where the vapor barrier is installed. But sometimes, a vapor barrier isn’t enough. Runoff (surface) water can penetrate foundation walls and ground water can seep up through the soil into your crawlspace. Then a French drain is needed to divert the water to a drain system which directs the water from under the crawlspace and away from the house. Sump pumps are sometimes needed when there is not enough “fall” on the outside of the house for a gravity drain to work properly.


Vapor barriers are simply sheets of polyethylene placed in the crawlspace in a way that prevents moisture from escaping into the air. A minimum of 6 mil is recommended to reduce the opportunity of ripping or punctures. In all cases, the edges of each sheet overlap the other sheets to complete a solid barrier. In crawlspaces where moisture is not really an issue, a simple vapor barrier with overlapping edges covering all areas up to the foundation walls can be sufficient. In other cases where ground water is present or surface water is suspected of penetrating the foundation walls, a super vapor barrier may be needed. The super vapor barrier overlaps the other sheets of poly and the edges are tapped. The poly is extended up the foundation wall until it is at least 6 inches above the exterior grade. This configuration forces the moisture below the barrier and into the drainage system.


Our French drains include corrugated pipe surrounded by 57 granite stone and wrapped in filter fabric. These pipes channel the water to either a catch basin with a sump pump installed or to a discharge line dug under the footer and piped away from the house where gravity lets it drain naturally.


All water in a crawlspace is captured by French drains and diverted either outside via a gravity drain or to a catch basin. Sump pumps are used to pump the water from the catch basin to an area far enough away outside so the water can’t re-enter the crawlspace.
