How Much Does a Radon Test Cost in Birmingham? ($295 Flat, Explained)
No range, no quote request, no "call for pricing." Our radon testing cost is $295 flat — one price, every home. Below: exactly what's inside that price, and how it compares to the cheaper (and pricier) ways to test a house for radon in Birmingham.
The short version: A professional radon test in Birmingham usually runs $150–$300. Ours is $295 flat, and that includes drop-off, a two-day test with a professional monitor, pickup, an independent lab reading, and a written report you can hand to anyone. No add-ons. A $20 DIY kit is fine if you're just curious, but not if you're buying or selling a house.
What you get for $295
What $295 Actually Covers
A radon test isn't just a gadget sitting in your basement for two days. Here's every step included in your flat price:
- Drop-off visit — we come to your home, walk the lowest floor you actually live on, and place the monitor at the right height and distance from windows and HVAC vents.
- Two-day (48-hour) test on a professional monitor — a calibrated continuous monitor (basically a small logging air-quality device), run under the national testing standard (ANSI/AARST). It records the radon reading every hour, along with temperature, humidity, air pressure, and a flag if it gets bumped or moved — not one guess at the end.
- Pickup visit — we come back in person to retrieve the monitor and pull the data.
- Independent lab reading — no extra fee — the recorded data goes to a lab that has no relationship to the person who placed the monitor (that's us). The lab's fee is included in the $295; nothing gets added at pickup.
- Written report — the lab's PDF, showing the hourly graph, your two-day average measured against 4.0 pCi/L (the level where the EPA says to fix your home), any tamper flags, and where the monitor was placed.
- A plain-English phone call — we walk you through what the number actually means before you make any decision based on it, and we email the same report to anyone you want on it (agent, buyer, closing attorney) so nobody's waiting on a forward.
The $295 is the whole invoice. No travel charge anywhere in Jefferson, Shelby, or St. Clair counties. No rush fee. No weekend fee. No "lab reading" add-on later. The test either happens for $295 or it doesn't happen — the number on your invoice doesn't change on the way to the bottom.
Why one flat price?
Why the Price Is Flat, on Purpose
A flat price does two useful things at once. First, it takes the game out of it. Nothing to add on, nothing to skimp on, no cheap package that leaves out the lab and no premium package that throws in something extra. The service is the same on a $200,000 slab home in Pelham as it is on a $1.2-million basement house in Mountain Brook: same monitor, same two days, same independent lab, same report.
Second — and this is the bigger reason — a flat price removes any pressure on the number. Our fee doesn't go up if the reading comes back high. It doesn't go down if it comes back low. Nothing about our price rewards the test coming back one way or the other. That's the whole business model: the number is just the number.
The other thing a flat price does is keep scheduling honest. A homeowner just curious about their own house pays the same $295 as a buyer racing a 10-day closing. The equipment, the standard, and the lab don't know which of you is on the phone — and neither does the price.
How does this compare?
How Radon Testing Cost Compares in Birmingham
We won't name specific competitors, but here's the honest range of what a radon test actually costs around Birmingham right now:
- Standalone professional tests in Birmingham generally run $150–$300, using a professional continuous monitor and an independent lab reading — the same category we're in.
- Add-on tests bundled with a home inspection typically run $150–$250 on top of the inspection fee — and the equipment used varies a lot depending on the inspector.
- DIY charcoal kits from the hardware store run $15–$40, plus a separate lab fee to mail the canister in for a result.
The price difference isn't just markup. A professional continuous monitor records hourly data and flags anyone bumping or moving it — if a window gets opened mid-test, the data shows it. A mail-in charcoal kit gives you one average number with no record of what happened during the test, and the lab reading it is often the same one that sold you the kit. Inspection add-ons are all over the map — some inspectors use a real professional monitor and send it to a real lab, others run a $20 charcoal kit and average it themselves. What you're really paying for at each price point isn't the number — it's whether that number will hold up if anyone questions it.
That's what matters most in a real estate transaction. A buyer's attorney, a listing agent, or a fix-it contractor can all reasonably ask, "how do we know that number is right?" A professional monitor run to the national standard and read by an independent lab comes with an hour-by-hour graph and a chain of custody — the paper trail showing who handled the monitor and when — already inside the PDF. That's a very different answer to the same question than "we averaged the charcoal reading in-house."
Compare at a glance
Radon Testing Cost by Method
| Method | Typical Cost | Who Reads It | What You Get |
|---|---|---|---|
| DIY charcoal kit | $15–$40 + lab fee | Mail-in lab, you set it up yourself | One average number, no way to prove test conditions |
| Inspection add-on | $150–$250 | Often the inspector | Depends on the device; rarely hour-by-hour |
| Independent lab-read test | $295 flat | Independent lab, not the tester | Hourly readings, tamper-flagged, full report |
When a DIY kit is fine
When a $20 Kit Is Actually the Right Call
There's a real, honest case for a DIY charcoal kit, and it's worth saying so on the pricing page instead of pretending every homeowner needs the professional version. A DIY kit is fine when you're just curious — "I've never tested this house, I want to know roughly where I stand, nothing is closing." A $20 charcoal canister and a mail-in lab fee will get you a rough, directionally useful answer. If it comes back well under 2.0 pCi/L, that means something — a professional test would almost certainly come back in the same neighborhood.
A kit is the wrong tool when the number has to hold up in a home sale, when it's going to decide whether you install a radon fix, when a first-round result came back near or above 4.0 pCi/L (the level where the EPA says to fix your home), or when a buyer, seller, or agent needs to be able to defend the reading later. A charcoal canister gives you one average number, no hourly data, and no chain of custody (that paper trail again) — which are exactly the three things a home sale, a mitigation quote, or a "wait, are you sure?" challenge will ask about first.

Common questions
Frequently Asked Questions
Is $295 really the final price? No hidden fees?
Yes — $295 is the whole invoice for a standard two-day test. That covers drop-off, pickup, the independent lab reading, and your written report. No surprise "lab fee" tacked on at pickup, no travel surcharge, no weekend charge.
Why do some home inspectors charge less as a radon add-on?
Cheaper usually means a small charcoal canister (like the DIY kits at the hardware store) instead of a calibrated professional monitor, and the inspector may read the result in-house instead of sending it to an independent lab. Lower cost usually means less data — not a different number.
Can I just buy a DIY radon test kit from the hardware store?
You can, and if you're just curious about your house it's a fine starting point. A DIY kit is a small charcoal canister — it gives you one average number, with no record of what happened during the two days. For a home purchase or sale, you generally need the hour-by-hour, tamper-evident data a professional monitor gives you.
Does the price change based on the size of my house?
No. The $295 price covers a standard single-family home with one monitor. Really large homes that need a second monitor location are quoted before scheduling — no surprises.
