Radon Mitigation

I ran a short term 3 day test and a long term 128 day test in my basement. Got a reading of 3.9 from both tests. EPA says 4 or above, fix it. If between 2...

Canadians have more inherent radon resistance. What's a little lung cancer risk when you can survive arctic temperatures?😂

Ya we have thicker skin. More biological sheilding. 😂

Houses are built too air tight today compared to the past...Open a window

raggmann54 Opening basement windows is mitigation.

raggmann54 I remember seeing this elaborate air exchange system that my sister had installed in her first house. I'm not going to say anything negative about radon, but I will say it seems to be more of an issue in the last 30 years....as houses have become tighter. Nearly every building product in your house is emitting formaltihyd or some other harmful chemical compound. The regulations on those have gotten tighter as well...all the way to the inside of the building membranes.

When we sold our house in Haverhill MA in 2002 the Radon test came back above the limit. Had to have a fan installed in the basement. Cost ~ $1000 dollars.

We had the "sub slab depressurization system".....I think that was the name?.... put in our first house and it was already in the next house. I have no doubt some company made some good $$ in this area when homeowners could have just installed a cheap fan. Better safe than sorry?

KCee could have just installed a cheap fan. Better safe than sorry?

The "regular" radon mitigation "system" is a PVC pipe running from the sump pump well in the basement, through the basement wall, up the side of the house and to the roof, with a simple electric exhaust fan somewhere in the pipe (outside, 5' above ground). Runs 24x7. Probably a few hundred bucks in parts.

Read this awhile back so I'm going by memory but if you have your house tested you must supply that information if you sell. So if you're on the cusp as someone said 3.9 with 4.0 being actionable and you don't fix it, you must make the buyer aware. If you don't they can come after you later. Something like that.
Also have heard just opening the basement windows if you have them is enough.

I know folks who were on the margins of the numbers but put in the system so they're resolved when they sell.

I don't have a basement and we do have a crawl space. So..... scot-free???

Tests are cheap. Get one at Lowe's. Place it in your crawl space for 3 days. Mail it in. Lab results are included in the test kit price. They email you the numbers. AlphaEnergy.com

rsvman2 In theory radon can escape out from the crawl space since they typically have vents. Depends how old your house is and how tight the floor is.

So today's choices are radon or sleet/snow/freezing rain and a massive heating bill.🤔🤔🤔

sdandrea1 Sounds like what we have and had in the old house. Yes it's not exactly a complex system.

sdandrea1 @rsvman2 Also free from the state. Did both in VA and New Mexico-bought one and got onr from the state. Never wrong to test then some info if to fix. When I sold my house they did not ask for a test and I did not offer. Agent did say if I know radon level is above the state recommended level, I have to disclose. Mine was below state level.

Bravopilot I'd venture to guess, if you don't have it by now.... Especially if you're already over the age of 70.

I've a feeling that in Pennsylvania we've got much higher rates of Radon. I know through personal experience, along with many relatives, that Thyroid disease in my region is twice the national average. As well, all real estate sales and purchases require Radon mitigation.
