Portland Radon Map – 2020 Update, Plus Free Tests (for some)

June 1, 2020

Portland Radon rates change. A perennial hot topic in Portland is the influx of Californians, but it’s really the Montana and Idaho migrants that we should be worried about, according to health officials. Actually, they’re not talking about people, but rocks. “In the Portland metropolitan area, a lot of the rocks and soil underneath the Willamette Valley were carried down from parts of Idaho and Montana,” said an Oregon Health Authority official quoted by OPB. These long-ago geological travelers carry radon, a radioactive gas that is drawn into homes and buildings, leading to cancer and other health issues.  As real estate agents, we do a lot of education about the risks of radon and the importance of testing, and in...

July 5, 2019

When it comes to choosing a home to buy in Portland — or anywhere — it’s all about location. Is it near a good school? What’s the neighborhood like? Can you see Mt. Hood?  There’s an aspect of location that most people don’t think about right away, but should be just as important in the decision-making process: The home’s proximity to natural hazards.  You might be thinking: Natural hazards? Portland? It’s true — Portland’s climate is mild, we do have a volcano in city limits but it’s very dormant, and overall this is a pretty safe place to live. On the other hand, there are some serious risks that home buyers — and owners — should take into consideration. Some,...

You never know until you test. Radon is a radioactive gas, invisible and odorless. You can’t see it, smell it or taste it.

Portland Radon – New Map 2015

March 25, 2015

As home shoppers tour your home with their buyer’s agent, they’re probably thinking about how big the bedrooms are, whether the kitchen appliances are updated, and how many people can fit on the back deck. What they might not know to ask is, “What’s the radon level like here?” That’s because radon is invisible and odorless, and is one of those things that home buyers expect to be taken care of before they close on a home.

Running radon tests well before you list your home with a...

Portland Home Tests: Radon Gas

May 14, 2014

What’s invisible, odorless, creeps in your basement, and kills 21,000 people a year in the US alone according to the EPA? The answer is radon gas, and to be more specific, it comes from naturally occurring uranium in the rocks and soil underneath homes, including many in the Portland, Oregon area. And homes without basements can have a radon problem, although it is less likely. Pro tip: If your Portland home is on a crawlspace, be sure that all the crawlspace vents are open and not blocked with debris. If the crawlspace is open and well ventilated the chances of failing a Radon test drop to nearly zero in the Portland area. Here’s what you need to know: Radon gas...

Portland Oregon Radon Map 2013

March 21, 2013

As a Portland real estate agent I’ve noticed that Radon testing is a growing trend, it has become more and more popular to test every home for Radon levels in the greater Portland Metro Area. It seems these days you can hardly find a home inspector that does not also include a Radon test option (for more money of course). I do not expect this trend to go away. If you are selling a Portland home you can expect the buyer will most likely test your home for Radon levels! It is to your advantage to be prepared and perhaps conduct the test ahead of time so you know what you’re dealing with. (Surprises are never good for real estate...
