Thousands of American homes today are situated in areas that are at risk of radon gas intrusion. Radon gas has become a health threat to many Americans with it being the second leading cause of lung cancer and other lung complications second only to smoking. Radon gas comes from underground which rises up to the surface and eventually finds its way into homes through cracks and crevices. High concentration levels of radon can build up indoors increasing the health risk of the household.
Thankfully, this problem is not unsolvable. The radon gas that builds up in people’s homes can be vented out into the open air outdoors thus reducing the levels inside the house. This process is known as Radon Mitigation. Today, we are going to go through common questions that people have regarding radon mitigation and help increase understanding around this important topic.
1.) What’s the common process in radon mitigation? – The most common process in radon mitigation is sub slab depressurization which uses a system that prevents further radon intrusion and sucks any remaining gas indoors.
2.) What are the costs of mitigation? – On average installing a radon mitigation system in your home will cost you around 1.5k dollars. The amount can vary depending on the type of mitigation system used and the amount of radon.
3.) Will radon levels decrease if cracks are sealed? – The cracks in the home aren’t the only entry point of radon so sealing them would do next to nothing. Radon gas can still intrude through the concrete slabs.
4.) Does painting help in preventing radon intrusion? – You might find paint brands that have advertised their paint as something that helps keep radon out. Well just like sealing cracks, this is virtually useless and Radon Mitigation is still the best option.
5.) Can radon intrude even without a crawlspace? – Crawlspaces are the most vulnerable areas, but as mentioned, radon can have more than one entry point into your home such as the slab, walls, etc.
6.) How long will installation take? – When done properly by a licensed professional (radon contractor), you won’t need to wait more than a few hours. After which, your system will be set up and ready to use.
7.) What is the ideal place to set up the fan? – In line with EPA protocol, the fan should be set up in the exterior of the house allowing it to work more efficiently in removing radon gas.
8.) Are big PVP pipes necessary – PVP piping is so far the only type of piping that is approved for use in radon mitigation systems by the EPA as other materials have had some complications.
9.) How long will the fans last? – The fans that come with your Radon Mitigation system come with a 5-year warranty upon installation. In terms of lifespan, fans have been found to last eleven years on average.
10.) Why do the pipes need to reach the top? – The reason why the other end of the pipes need to go up to the top is so that the radon gas can be vented out into the air much further from the ground.
