radon gas in my condo in naples (University: 2015, home builders)

[piuliano]

i just contracted to buy a condo (first floor of two stories) in naples. during inspection radon was found. a radon mitigation system is being installed by a reputable company. my question is once installed can i feel comfortable that this installation will correct the problem long term. just curious if anyone had this done and are satisfied or have they experienced problems that i should be aware of. thanks

You're good to go. They will tell you how to monitor that the system is working properly moving forward.

Radon mitigation is a pretty sure bet. Our son has dealt with it in the northeast with no issue.

Research conducted by the University of Central Florida's Solar Energy Center revealed that out of 21 ventilation systems they inspected, only one performed as it should.

If you have a ventilation (fresh air) system installed in your home, it would be a good idea to acquire a radon meter.
You can get one from Ebay for about $140.00.

Mold is a common occurrence after fresh air radon system installations in hot, humid climates
Do not rely on one of those U-tube manometers filled with blue oil.
They are not designed for nor do they provide correct indications of ventilation radon system operation.

Good luck on the new hope. It is very good the seller has to add the system before the close.

What were the levels before mitigation? The recommended EPA action level is 4.0.

I have a radon system in my new home (not in Naples) which I did for piece of mind as the test came out just over 4.

But here’s the rub - the risk factors are extrapolated from lung cancer rates experienced by miners who were in extremely high Radon areas, working many hours a day for decades.

The risk factors assume something like 18 hours a day in a closed environment. For DECADES. That’s not realistic.

Go outside? Reduces risk. Go out for some shopping and dinner? Reduces risk. Leave the doors and windows open to get a breeze when the weather is nice? Reduces risk. Go visit family for 2 weeks? Reduces risk.

While Radon is touted as the second leading cause of lung cancer I haven’t been able to find examples in an average home where lung cancer could definitively be pointed to Radon as a cause. I’m not doubting it’s dangerous, just that it’s not a death sentence, especially if the pre-mitigation levels are reasonable.

That’s why you need before and after readings.

I realize you are selling something here, but I think you are also being vague.

The manometer has nothing to do with “ventilation”. It’s for sub-slab depressurization and shows if there is negative air pressure in the system to draw away Radon from under the foundation. Any system using this method should have a manometer and it is ventilating nothing in the living space.

I do agree that no matter what system you use, a Radon meter is a good thing. I have a very large basement and have 2 from Airthings.

You are absolutely correct! These questions are always evaded. How long must you stay in your completely closed house before this radon level has an affect on you? Most people don’t realize that a test taken on Tuesday that falls below the acceptable level of 4.0 pCi/L can be above 4.0 on Saturday. If you look where radon is predominately high, you will find that cancer levels do not coincide. Is radon an overblown issue? You can decide for yourself.

You can also buy a twin radon kit at Lowes or similar. 2 small paint can type cups per package.

Very similar in size the model paint cups.

Follow easy directions.

Open on in on location , another in a 2nd location, leave undisturbed for a few days per instructions the cap the lids. Mail back to the company and get results back in a few days. Some states the radon company can charge a $10 fee or so for results, others states they can not charge a fee.

At least with these indications you can determine if your system is working or needs an adjustment.

I had to install a radon system back in the day for my new built home in PA. Worked as expected.

Good luck with your system!

Quick question, we are planning to relocate to Naples from Virginia (we will try not to add to the traffic congestion). Is radon a common issue on the newer single floor homes built on a slab? Do the new home builders offer radon solutions if too high? Thanks
