How to Explain Radon Mitigation to Homeowners Who Can't See, Smell or Taste the Problem

Plain words a radon mitigation company can use to explain a problem nobody can see, from the first phone call to the kitchen table.

Most homeowners have never thought about radon, and when they do, it sounds made up. A gas in the basement that you can't see or smell, that a little box on the shelf says is there? You know it's real. Your job is to help them believe it without scaring them off the phone.

This is a guide to the words that work, from the first call to the day the fan goes in.

Why is radon so hard to explain?

Every other trade has something to point at. A roofer points at the water stain. A plumber points at the drip. You point at a number on a test report.

That makes people suspicious in a particular way. They don't think you're lying, exactly. They think it's one of those things the inspector found so the buyer could knock a few thousand off. Or they figure their grandparents lived in the house for fifty years and were fine.

So don't argue with the feeling. Give them something solid to stand on instead:

• A source that isn't you. The EPA says radon is invisible, that you can't see or smell it, and that testing is the only way to know your level.
• A number that means something. The EPA recommends fixing a home at 4 pCi/L or more, and says to consider it between 2 and 4.
• A plain picture of where it comes from. It rises out of the ground under the house and comes in through cracks and gaps, the way the EPA describes it.

Once those three are on the table, you're not selling. You're explaining.

What should you say on the first phone call?

Keep it short and calm. People call you after they get a number they don't understand. Something like this works:

"Thanks for calling. First thing, this is fixable, and it's a common fix. What did your test say? Okay. The EPA says to fix anything at 4 or above, so you're in the right place. Here's what we'd do, how long it takes, and what it costs."

Notice what's missing. No lecture on lung cancer, no pile of numbers. If they ask about health, answer honestly and point them to the source. The EPA's health risk page says radon is the number one cause of lung cancer among non-smokers, by its estimates. Say it once and let it sit. Repeating it makes you sound like you're pushing.

How do you explain the fix itself?

This is where most explanations go wrong. The installer knows every part of the system, so the explanation turns into a parts list. The homeowner just wants to picture it.

Try a picture they already know: "The gas is coming up from the dirt under your floor. We put a pipe down through the slab and a quiet fan that pulls it out and sends it up above the roof, before it gets in the house. You'll see a pipe and a small gauge. That's it."

Then answer the three questions they're actually thinking:

• Will it be ugly? Show photos of past installs on houses like theirs, with the pipe run where you'd run it on their house.
• Will it be loud? Tell them honestly what they'll hear, and where.
• How will I know it worked? Explain the retest and what the gauge shows. This is the part a doubter cares about most.

What about the buyer, the seller and the realtor?

A lot of radon work happens during a home sale, and you're often explaining to three people at once who want different things. The buyer wants to be safe. The seller wants it done fast and cheap. The realtor wants the closing to stay on schedule.

Give each of them one sentence. To the buyer: "Here's what the retest will show." To the seller: "Here's the date we can be in and out." To the realtor: "Here's the paperwork you'll have for the file." Then put all of it in one short email they can forward. Who pays for what is between them and their agents, and it's worth saying that out loud.

Where a song fits

Here's the honest trouble with radon: people forget about it until a test makes them think of it. A two-minute story that a homeowner can watch on your website or Facebook page does some of the explaining before they ever call. It can tell the whole thing in order: the gas they couldn't see, the test, the fix, the quiet fan, the retest.

We made a sample like that, The Stranger in My Basement, a country blues song for an example radon company. You can watch it on this page. Here are two example lines, written fresh for this post, to show the idea:

There's a stranger in my basement, never knocked and never came in by the door. / Couldn't see him, couldn't smell him, but the little box said four.
