What is Radon Mitigation?
Radon mitigation is the method for reducing Radon in your home. There are many ways Radon can be reduced. A Radon Professional can help you decide which method is the best and most cost effective for your home.
Why Radon Mitigation?
The goal of a radon mitigation system is to reduce the indoor radon levels to the lowest possible levels for your home.
Types of Radon Mitigation Systems
As of June 2009, all new construction homes in Minnesota are required to have a passive Radon system per the energy code. However, 25% of those homes will still test high. A test is recommended prior to closing.
The most common method used today. A suction point is created under the slab of the home, a pipe is routed from the suction point to the Radon fan which pulls the air from under the slab and exhausts it harmlessly to the exterior. The Radon fan can not be installed in the living space . It must be installed on the exterior of the home or in an attic. A Radon professional can help you decide the best option for your home and budget.
Crawl spaces with dirt floors can be a major Radon entry point. They are normally sealed with a vapor barrier that is air tight and a suction point under the barrier can be added if deemed necessary by the system designer.
Often a combination of these methods will be employed to reduce the Radon. A Radon professional will perform diagnostic testing to detemine the best system for your home and budget.
Some homes may require specialized methods to reduce the Radon. Block wall depressurization, Sub-sump depressurization, and others.
Questions To Ask Radon Contractor
Do they use Quality parts?
- Some contractors will use schedule 20 pipe instead of the more expensive schedule 40. Schedule 20 pipe can freeze and break in our rough winter conditions. The AARST/ANSI standards call for schedule 40 in cold weather climates like ours.
- Some use cheaper Radon fans, that just won’t last as long as the quality fans used by the Radon professionals.
- We use the highest quality fans and only quality components. Our fans average a lifespan of 12-15 years. Pretty good for device that runs 24/7!
Are They Certified Through NRPP and follow the new AARST?ANSI standards?
- Minnesota does not license Radon Mitigation Contractors. YET It is essential that the contractor you hire is certified by the NRPP. It ensures that there has been some basic training and requires a passing score on a National Exam. Certification also requires annual Radon continuing education.
- Companies that do not follow the new AARST/ANSI standards expose their clients to elevated Radon levels from improper installation all the time. The systems also will not last and will need to be fixed and brought up to standards at a greater cost. The Radon Guys have fixed many of these “cheaper” installations by contractors who simply do not know what they are doing. The client ends up paying more to have the work redone correctly.
- The Radon Guys installation crews have been certified and are current with the NRPP. We insist on annual training and no one does a job without certified supervision.
Experienced with Radon installations
- We have seen many installations that work right away but will not last. The systems are not properly installed for condensation issues and will cause premature system failure and need to be repaired within a few years.
- We have been helping homeowners with Radon issues since 2000. Radon mitigation is the Radon Guys’ sole focus. It is all we do, and we have done it thousands of times.
Do they offer a warranty that covers parts and labor? How Long?
- Some companies offer a lifetime warranty. Ask them what that covers. Likely not the fan nor the labor to repair a faulty fan.
- All systems installed by the Radon Guys are backed by a Five Year “No Quibble” Parts and Labor warranty. If at any time during the first 5 years, your system does not work…you call us we fix it! No charge for labor, travel, or components! If testing after the installation is above 4.0 p/Cil, we fix it until it is below 4.0 p/Cil. We simply stand behind our work.
Do they do a post installation test?
- The Radon levels HAVE to be checked after the installation to ensure proper operation of the system. Some companies give their clients a long term test, which has to run 90 days. That means if the system isn’t working properly, you will continue to be exposed to high levels of Radon during the testing period. A short term test should be done within 1 week of installation. Some companies do not test at all. That is unacceptable.
- The Radon Guys will give you an approved, highly rated test kit to test for Radon after the installation. You do the test and the lab reports the levels. Simple. Honest. Complete. That’s how we work!
