Contact the Housing Section of your Local Authority for further information. Where a suite of works is being grant aided under this scheme, Local Authorities may also, as part of the package of works, assist with the provision of radon remediation works, where applicable. However, the most suitable method will depend on the radon levels and on the type of building.Ī Scheme of Housing Aid for Older People is available to assist older people, generally over 65 years, to have repairs or improvements carried out to their homes. Other less expensive options are available, for example, improving the ventilation in your home by installing extra wall vents. However the typical price of retrofitting a radon sump into a standard house is approximately €925 (ranging from €400-€1500). Some radon reduction techniques are more expensive than others and each one will need to be assessed on a case by case basis. The most accurate and expensive devices are continuous radon monitors that can take radon samples every hour and average them into a meaningful reading in.
#RADON SYSTEM MONITOR READINGS INSTALL#
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.There is no grant available to cover the cost of radon remediation. 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. 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. During any extended absence, the mitigation system should be turned off. The mitigation system should only be running when the property is occupied, is "closed up", and with the air handler on. You) that adds resistance to radon gas, and makes it more difficult to enter in the We do this for two reasons:ġ) The outside air has an average radon level of 0.4 pCi/l, so bringing this air into aĢ) Bringing fresh air in creates a slight, positive pressure change (unnoticeable to 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. 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.Ī mitigation system is essentially a ventiliation system that brings fresh outside air into the property, to the return air supply of the air handler. Any short-term test result can be a little higher or lower than a long-term test average. Although the average was 3.5 pCi/L (pico-curies per liter of air), the readings ranged from 1.0 to a peak of 8.1. The correction, or process of reducing radon levels, is called mitigation. The graph below shows the hourly change of radon levels over a two-day standard test for a recent real estate transaction.
When an elevated level of radon is discovered (4.0 pCi/l or above), it can easily be corrected. 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.

At that time, a determination can be made as to proceeding with a full survey, or if remediation is needed. Should these suspicions arise or visible mold problems become apparent, our clients will be informed immediately. A report is provide that identifies the fining, laboratory analysis, descriptions, and pathogenicity of organisms detected in testing. We also check for signs of water intrusion (upon request) that present a potential mold contamination risk. Mold concentrations inside should be less than, or relatively equal to (very slightly higher) than the outside concentrations. The inside sample is then compared to the outside sample, which establishes the normal or baseline. 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 process starts with retrieving an inside air sample(s), and then an outside air sample. The purpose of a screening is to ascertain if a present mold problem exists within a residence that is being considered for purchase/sale.
