Relocate to Wisconsin : No Basement...No Radon...'Right ? Wrong !

No Basement...No Radon...'Right ? Wrong !

      In  southeastern Wisconsin, and many other parts of the country, Radon gas is prevalent and if a property does not have a mitigation system in place, a radon test is veRadonry often included in the offer to purchase.  Most properties in southeastern Wisconsin have basements...often with elaborate finishes from media and game rooms to wet bars, kitchens, offices, bedrooms, full baths, saunas...every square inch of the house that can be used is...for things other than just storage or the laundry room.  All the more reason to include a radon test in an offer...OR ...have your home tested for radon if it does not currently have a mitigation system.

     When a house is tested, the meter is usually placed in the basement where it remains undisturbed for a couple days and then the results are read.  Radon is a gas and the levels will vary during any given time period. If the average exceeds the governmment's recommended level.Radon mitigation sytem

     Radon gas is created fron the natural breakdown of uranium in the soil, rock and water and moves through the ground and into the home. It can come n thru the sump pump, cracks in the foundation AND thru well water.

   IF the property is located in an area where levels of radon are can also enter through windows and floor drains....which do not have to be in the basement...this can be in a condo or home that does not have a basement.

    While this may not be a "glamorous" part of a home....getting a test and if necessary, having a mitigation system installed is a good investment in your health since some research indicates the presence of radon can be linked to some kinds of cancer. 

        Just because your home may have had a test below the recommended goverment standard at one time...Remember radon is a gas and that level can change at any time.  There are monitoring systems that can be installed as well to protect you from changes that may occur in these levels.

       Home radon opposed to those done by professionals have been shown to have varying degrees of effectiveness and we recommend having the test done professionally.

     This is a safety reminder post brought to you by Sally K. & David L. Hanson, Broker Associates with Keller Williams Realty honored to be of service for all things real estate in southeastern Wisconsin.

Good morning Sally. Radon, radon everywhere! A test is critical even in highrise condominiums with granite finishes. Granite has radon! Enjoy your day!

Good morning, Sally K. & David L. Hanson we often see readings within the home .... rarely on the second floor but often on the first.... very high in the basement....

One time (only) did I have a house on a slab found to have radon.

However, if you read all the EPA and radon literature (which I have, and it's as exciting as a washing machine repair guide) it is only "suggested" that radon "may" have a "possible" link to cancer.  And there is no empirical evidence that low-dose radiation causes cancer (see dental x-rays...).

Good morning, Sally and David. Radon inspections/ testing/ev idence is not as common in our area as in other parts of the country. It's good to be aware what's happening in other places especially for those relocating outside the area.

Hi Sally, if I lived in your area, I'd definitely have a radon test and recommend to all of my buyers. It's not such a big factor in my area and while some percentage of buyers do radon tests, I've only had one instance where there was ever a problem noted and remediation was required.

There are a lot of agents who incorrectly think this way and advise their clients accordingly !

Radon gas testing is not common here on Long Island. As a matter of fact, 6 months ago we had a buyer from out of state who told us he had to have an inspection for it before purchasing a home. His attorney assured him that it would not be necessary, but we do realize this is prevalent in other areas.

Sally, great post, and when I have buyers buying into a condo complex on the ground floor, I always recommend a radon test.

The cost of getting a radon test is what likely leads to them not getting it, but they need to realize that the cost will be much steeper if there is radon in their new home and they didn't get it taken care of.

We don't deal a lot with that here but, on occasion, a buyer will have a radon test done - it's not often though. We did have two complexes here in our area that were sealed so tightly, even the radon levels on the top floors were significantly elevated, Sally. One of the complexes was able to sue the developer and had him remediate. The other one is still a work in progress - many homeowners have had it done but, some remain that have not been remediated.

The cost is not that significant - I don't know why homeowners don't just do it!

We have high levels of radon in pockets of Clark County and it's always wise to get a radon test done when purchasing ( or selling a home to be proactive). We had one last year with radon a tiny bit over the recommened safe levels - and yes the sellers had to install a system for mitigation. The good news it can be managed.  The more people are aware, the safer they will be...

Several years ago that was a very hyped test around here. We are lucky not to have this gas avail in our area. I have never had a positive result in 19 years Sally K. & David L. Hanson

This is an important topic and radon tests are usually part of the process in our market.

Hi Sally - when we bought in Northern VA our home was tested and passed. Then when we sold it about 4 years later, we had it. So, you're right, you don't know even though it was tested earlier.

Sally and David just like a home inspection Buyers should consider a radon test a must to do.
