The Only NO-Mold Limited Warranty in the Industry

Visits

Mold may be most easily controlled by maintaining moisture at levels that molds cannot grow. Water vapor transported unintentionally through a building's matrix can easily condense on a cooled surface, even within wall cavities where it cannot be seen. Identifying and correcting such unfortunate issues can be done quickly and economically by the use of specialized, rare instrumentation.

With only rudimentary testing, some radon mitigators claim that air conditioning systems will remove all moisture necessary to prevent mold growth  from the radon systems they install. This is NOT SO. Just because you have cooling does not mean that you have dehumidification. Many air conditioning systems have little or no reserve capability of dehumidifying additional ventilation air. "The straw that broke the camel's back" and indoor moisture begins its march to levels that support major mold blooms and destruction.

Key Benefits

Capabilities

Building Science Knowledge

We have studied under the best building scientists in the United States and performed our own experiments for over ten years. We have developed protocols, technologies, electronics and hardware to put our knowledge to work.

Building Exterior and Interior Envelope Pressure Testing

We have acquired the skills and necessary instruments to evaluate exterior and interior envelope integrity quickly and accurately. Once set up, our computerized blower door can provide an accurate report indicating a building's leakage issues by performing 800 tests in about seven minutes. There is no substitute for such data when undertaking to solve building problems. Guesswork does  not work.

Zone Pressure Testing

We utilize new software developed by Renowned Building Scientists to evaluate building pressures by zone. The resulting data provides additional insights into the origins of sick building, moisture, mold and radon problems allowing us to more quickly and effectively solve indoor air quality problems.

Duct Leakage Testing

Our Duct Leakage capability allows us to quantify and locate air leaks in both the supply and return ducts of air conditioning systems. Duct leakage can result in attics that are cooler than the breathing zone, causing high utility bills and serious mold issues. Duct leaks can result in transportation of fiberglass insulation, mold spores and other contaminants throughout a home.

Air Handler Flow Rate Measurements

Air handler flow rates are important. If the air passes too quickly through them, they do not perform well. If the air passes too slowly through them, likewise they do not perform well. Using our True Flow Gage Instrument, we are able to evaluate the actual airflow and tune it as necessary to achieve optimal system performance.

MultiChannel Data Acquisition

Our sixteen channel data acquisition system allows us simultaneously to monitor a building's operating characteristics in real time including temperature, humidity, dewpoint, and micropressures as low as 0.02 pascals and to log such data to charts for our careful evaluation in identifying what is wrong to make a building sick. To be able to monitor so many points simultaneously allows us to reach conclusions in a fraction of the time required by lesser instrumentation.

Delta t Datalogging

Air conditioners need to cool and heat the air passing through them at optimal rates. If they fail to do so, poor performance results. By testing for delta t, we are able to predict if a home is likely to develop mold or other air quality issues long before they occur.

Carbon Dioxide Datalogging

Our CO2 datalogging instruments allow us to accurately measure actual ventilation rates when buildings are occupied by varying number of occupants. In hot,  humid climates, when buildings are over-ventilated, they tend to have odor, moisture, microbiological and mold problems. If a ventilation system is not performing properly, we can immediately identify and document the origin and choose a corrective measure. VERY often, ventilation systems perform poorly and indoor air quality suffers.

Temperature, Humidity and Dewpoint Datalogging

Using our individual dataloggers, we are able to evaluate and document building operation for over 8000 data points over a period of time. We are able to determine and document what area in a building is operating poorly.

Power and Voltage Datalogging

Our power dataloggers allow us to measure the power consumption and timing of operation of air conditioners, pumps, dehumidifiers, fans and heaters during normal building operation. The resulting charts assist us in finding the true causes of building operational problems.

Digital Micromanometers, Thermohygrometers, Thermometers

These instruments allow us to take accurate spot measurements to guide us in short term measurements.

AOC Mold Measurement Systems

This system allows us to make accurate measurements of airborne, non-viable mold samples for comparison with outdoor samples. We find that it is not unusual to record exposures of 29,000 mold spores per cubic meter of outdoor air in SW Florida. We like to see indoor levels of 300 mold spores per cubic meter indoors. A radon system without HEPA filtration can easily deliver 29,000 spores with every cubic meter of outdoor air brought into the home. Mold Spores are Seeds. It is not unusual for an unfiltered radon mitigation system delivering 80 cubic feet per minute to deliver two cubic meters of air per minute containing 29,000 mold spores in each cubic meter.
*2 cubic meters of outdoor air per minute X 29,000 mold spores per cubic meter X 60 minutes per hour X 24 hours per day = 77,760,000 mold spores (seeds) per day injected into a radon mitigated home each day.
*In addition, it is not unusual for an uncontrolled radon mitigation system to inject 100 to 200 pounds of water a day into the ductwork and the interior of the home where only a part of it is removed by the air conditioner. The rest soaks up into the furniture, drywall, drapes, photographs, shoes, etc. and continues to soak up as long as the radon system continues to operate.
*Sooner or later, the moisture is high enough to support mold growth ,and by planting 77 million mold spores a day into the home, is it a surprise that mold starts to grow as a result of radon mitigation system operation?
