How much does radon testing cost?

0:00 What This Video Covers
In this video, we are going to walk through everything a homeowner needs to know about radon, what it is, how to test for it, what the results mean, and exactly how much it costs to fix. We are building this one concept at a time. So even if you have never heard the word radon before, you will finish this video with a complete picture. Let’s get started.

0:22 Who Jeremy and PushLeads Are
A quick word on who I am, I’m Jeremy, I run PushLeads, and I built my career on getting homeowners buying, selling, or concerned about radon ranked and called. I founded PushLeads in 2012 after years of proving this on my own projects first. So let’s get into exact radon testing prices and the number that forces mitigation.

0:42 Four Key Radon Terms Defined
Before anything else, let’s lock down four key terms you will hear throughout this guide. Radon is a colorless, odorless radioactive gas. You cannot sense it in any way without a detector. PCIL stands for pico curies per liter, and that is the unit on every radon test result you will ever read. ASD stands for active soil depressurization, the most common and effective fix available, and action level is the concentration at which health authorities tell you to stop waiting and do something.

1:13 How Radon Enters a Home
So how does radon actually get into a home? It forms when uranium and soil and rock breaks down naturally underground, and then it seeps upward. The most common entry points are cracks in foundation floors and walls, construction joints, and gaps around pipes. Some pump openings are a direct, often unsealed pathway straight from the soil into your basement. The important thing to understand is that no foundation type is immune. Basements, slab on grade, and crawl space homes can all accumulate radon. The only variable is how much.

1:48 Health Risk and EPA Action Level
Here is why this matters so much. The EPA estimates radon causes 21,000 lung cancer deaths in the United States every single year. That makes it the second leading cause of lung cancer in the country behind only cigarette smoking. Roughly one in 15 homes has radon at or above the EPA’s action level, and because you cannot smell it, see it or taste it, millions of people are breathing elevated concentrations right now without knowing it. Testing is the only way to find out where you stand. Two different health organizations give you two different numbers to know. The EPA sets its action level at four PCI, meaning at that concentration, you need to act. The World Health Organization sets its threshold lower at 2.7 PC wash L because the WHO’s position is that there is no safe level of radon exposure at all. Risk rises in a straight line with both concentration and time spent in the home. If your result lands between two and four, you have a choice to make at four and above. That choice is already made for you.

2:56 Four Testing Options and Costs
Now let’s walk through your four testing options in order from least expensive to most. A DIY charcoal canister costs 10 to $30 including lab fees, sits in your home for two to seven days, and mails to a lab perfect for a first look. A long -term alpha track detector costs $15 to $50, runs for 90 days or more, and captures seasonal swings for a more accurate annual average. A professional 48 -hour test costs $150 to $300 and is the standard for real estate transactions. Finally, consumer electronic monitors like the AirThings Wave cost $150 to $250 as a one -time purchase and give you ongoing year -round readings. Let’s put the numbers side -by -side so they are easy to remember. A DIY charcoal canister with lab analysis runs 10 to $30. A long -term alpha track detector costs $15 to $50. And a professional certified test for a real estate transaction runs $150 to $300. The test type you choose should match your purpose a quick screen before deciding whether to go further, an accurate annual average for a mitigation decision or a certified result required by a transaction deadline.

4:10 How to Read Your Test Results
Once you have your results in hand, here is how to read it. Below two PCI shell is low risk. Retest every two to five years and move on. Two to four PCI shell is moderate. The EPA says consider mitigation and the WHO says act now. Four to eight PCI shell is the EPA’s official action level. At four, a non -smoker has a one -in -one 100 lifetime risk of lung cancer from radon alone. A smoker at that same level faces a one in 12 risk. At eight PCI well and above, the EPA compares the risk to smoking roughly half a pack of cigarettes per day. Treat that as urgent.

4:49 Mitigation Methods Explained
The most common and effective fix is an active soil depressurization system. And here is how one works. A contractor drills a suction point through the foundation slab into the gravel or soil below. PVC pipe routes radon from that point up through the house and above the roofline. An inline fan mounted on the pipe creates constant negative pressure beneath the foundation, actively pulling radon out before it can rise into the living space. That radon is then discharged above the roof where it disperses harmlessly into outdoor air. Installation takes four to eight hours for most homes. And the fan uses about as much electricity as a 75 -watt light bulb. ASD is not the only option. For crawl space homes, submembrane depressurization lays a polyethylene sheet over the soil and uses a fan to pull radon from beneath it. Effective and also good for moisture control. Heat recovery ventilators increase fresh air circulation, but only reduce radon by 25 to 50%. So they work best as a supplement to ASD, not a replacement. Ceiling cracks helps reduce entry points but is never sufficient on its own. And if you are building a new home, radon -resistant construction features, passive piping, vapor barriers, sealed penetrations, cost only $350 to $500, far cheaper than retrofitting a system later, cost depends heavily on your foundation type. For a standard basement or slab, active soil depressurization runs $800 to $1,500 with a national average of $1,200 in 2025 according to HomeAdvisor. Crawl space submembrane systems run $800 to $2,500 depending on size and access. Homes that need treatment for both a slab and a crawl space pay $1 ,500 to $3,500. Heat recovery ventilators, which are supplementary, run $1,500 to $3,000, but deliver far less radon reduction. In high -cost markets like New Jersey and New York, expect to pay $1 ,400 to $2,500 even for a single -point system.

7:02 Step-by-Step Mitigation Process
Here is the exact sequence most homeowners follow once they get a result at or above for PCIRL. First, confirm the result with a second test, especially if your first was a DIY kit not run under closed building conditions. Second, get at least two written estimates from AARST certified contractors. Each estimate must include system type, number of suction points, pipe routing, and whether post mitigation testing is included. Third, schedule installation, which typically happens within one, two, three weeks, and takes a single day. Fourth, run a post mitigation test at least 24 hours after the system activates. Your target is below four PCIRL, ideally below two. Fifth, retest every two years going forward to catch any drift before it becomes a problem again.

7:52 Radon in Real Estate Transactions
Radon has become a standard part of real estate transactions. Testing happens in roughly 40% of home sales nationally, and that rate is much higher in high -radon states. If a buyer discovers elevated radon during inspection, they can request the seller install mitigation before closing, negotiate a price reduction, or walk away. Sellers who test and mitigate before listing remove that negotiation entirely. A documented working mitigation system with post mitigation results below four PCIRL is viewed positively by buyers, their agents, and lenders. Illinois mandates radon disclosure on all residential sales, Florida, Pennsylvania, and several other states have their own disclosure requirements. Knowingly, concealing a radon hazard after testing creates legal exposure for sellers in most states. To put the risk in plain terms, the EPA’s own comparison chart says that a radon level of four PCIRL carries a one in 100 lifetime lung cancer risk for non -smokers. That is five times the risk of dying in a car crash. The outdoor air average across the United States is about 0.4 PCIRL. The average indoor level is 1.3 PCIRL. If your home tests at 8 or 10 PCIRL, you are breathing air with 20 to 25 times the radon concentration of outdoor air every day you spend at home. This is not a theoretical risk. It is a statistically significant hazard by any public health standard.
