When an elevated level of radon is discovered (4.0 pCi/l or above), it can easily be corrected. The correction, or process of reducing radon levels, is called mitigation. The method of mitigation we use in Southwest Florida is called Mechanical Ventiliation, Pressurization, and complies with the State of Florida Standard for Mitigation of Radon in existing buildings, Chapter 9b-53, F.A.C., June 1, 1994.
A mitigation system is essentially a ventiliation system that brings fresh outside air into the property, to the return air supply of the air handler. The air handler then draws the outside air in, removing the humidity, as it is recycled evenly through the existing duct, and supply registers around the property. We do this for two reasons:
1) The outside air has an average radon level of 0.4 pCi/l, so bringing this air into a
property will dilute the radon levels.
2) Bringing fresh air in creates a slight, positive pressure change (unnoticeable to
you) that adds resistance to radon gas, and makes it more difficult to enter in the
The mitigation system should only be running when the property is occupied, is "closed up", and with the air handler on. During any extended absence, the mitigation system should be turned off. During the the fall and winter when temperature and humidity are lower, and the property is "opened up" while occupied, you can turn the mitigation system off. For those of our clients who, knowing this, and are still uncomfortable with the air handler removing the humidity brought it, we can also offer an additional dehumidifier.
In single family homes, we can install the system(s) in the attic space, and in condos (without garages) we can install the system above the existing drywall ceiling, or conceal the duct within a framed and finished soffit.

The purpose of a screening is to ascertain if a present mold problem exists within a residence that is being considered for purchase/sale.
The process starts with retrieving an inside air sample(s), and then an outside air sample. This will tell us how many individually identified mold spores, pollen, dust mites, insect parts, fibers and miscellaneous particulates that are airborne per cubic meter. The inside sample is then compared to the outside sample, which establishes the normal or baseline. Mold concentrations inside should be less than, or relatively equal to (very slightly higher) than the outside concentrations.
We also check for signs of water intrusion (upon request) that present a potential mold contamination risk. A report is provide that identifies the fining, laboratory analysis, descriptions, and pathogenicity of organisms detected in testing. Should these suspicions arise or visible mold problems become apparent, our clients will be informed immediately. At that time, a determination can be made as to proceeding with a full survey, or if remediation is needed. For times where a visible, questionable substance is discovered, we also offer a swab analysis to determine if the substance in question is mold, or not.
We use the most sophisticated radon test monitors available. Offered by Radalink, an accredited, and nationally recognized analytical laboratory located in Atlanta, GA,
these monitors cost around $2,000 each to manufacture, and are recalled regularly for re-calibration in a laboratory with a controlled radon concentration.
They detect any unusual readings of radon, temperature and humidity caused by opening the surrounding doors or windows. Tilt and power sensors detect if the monitor is moved to a different location. Hourly barometric pressure readings will even help detect unusual radon averages due to extreme weather conditions. All data is reviewed for any sign of suspected tampering by Radalink's team of trained professionals.

Radon Mitigation Systems
*Radon Testing (Available upon request)
*Termite Inspection (Available upon request)
Whenever buying (or in some cases, selling) a property, it is of the utmost importance to hire a licensed, experienced Home Inspector to protect your investment.
We hold licenses through the Department of Business & Professional Regulation for Home Inspections and Mold Analysis, and prior to that, had been members of N.A.C.H.I. (National Association of Certified Home Inspectors) for years.
A thorough home inspection covers everything from A to Z with only a clearly defined list of exceptions. When we perform an inspection for you, we look at the things you may not have seen or have the skills to recognize as problems.
Items that are included in our inspection:
A/C and Heat
Chinese Drywall (Available upon request)
Garage Doors and Openers
*Mold Testing (Available upon request)
