About mitigation
To learn how Radon Mitigation Systems, LLC can lower the Radon levels in your home, call us for a free in-home estimate at (605) 261-4440.
We will design a radon reduction system as an integral part of your home. The system will be designed so as not to create additional environmental, health, or safety hazards, nor will it compromise the integrity and comfort of your home environment. Installation, operation, and maintenance cost will be determined and discussed during the design stage.
What to expect
The most cost-effective of the approaches we use is sub-slab depressurization. This system integrates PVC pipes with an exhaust fan. We connect a PVC pipe to the soil either through a hole in the slab of your basement floor, a sump pump lid, or beneath a plastic sheet in the crawl space. This system creates a lower pressure in the soil both in and around the structure when compared to the indoor pressure, thus preventing the transference of radon and other soil gases to the inside of your home.
Additionally, we seal cracks, holes, and other openings to the substructure of the building to reduce the amount of flow necessary for controlling the pressure difference between house and soil. This increases system effectiveness, while also reducing thermal losses and fan requirements.
After completing the installation, a professional independent testing lab should re-test your indoor Radon levels. This post-completion test provides proof that we have done our job correctly, and will remove any conflict of interest (from both Radon Mitigation Systems and the homeowner).
Questions to ask
How far away from windows and the eve of the house should the Radon discharge vent be, and why?
Answer: Above roof eave - 12 inches is good practice and a minimum of 10 feet from any opening, less than 2-feet below exhaust to prevent re-entry of radon into the home.
Why does Radon Mitigation Systems, LCC never use schedule 20 PVC pipe or rectangular downspout in their Radon removal systems?
Answer: Schedule 40 reduces noise from air turbulence.
Can a Radon reduction system remove the need for dehumidifiers?
Answer: This is possible because the system vent moist air out of the home prior to it entering your home.
Why is it important to have an in-home estimate?
Answer: All home structures are different and designs vary. We want to install the most efficient system. One that is custom designed for your home. Costs will vary with design.
Why is it a good idea to use a professional testing company for a re-test within 24 hours to 30 days after the work has been completed?
Answer: The physics of Radon takes 24 hours to stabilize to a testable level after a mitigation system is installed.
I'm selling my house, and my contract calls for a certified contractor. How do I know you are certified?
Answer: You can find my certification on the website for the National Enviromental Health Association, www.neha.org
