Radon testing
Short-term and long-term testing done properly — closed-house conditions, the right placement, and results you can actually read.
Radon is invisible and odorless, and it varies house to house — even next door. The only way to know your level is to test. If it comes back high, mitigation is a proven, quiet system that vents radon from beneath the home before it gets inside. We test, explain, and, when needed, install and retest.
Worth a closer look if you notice…
- You have never tested, or it has been years since the last test
- You finished a basement, added a room, or changed how the home is heated or ventilated
- A neighbor or a nearby home tested high — radon varies house to house, but it is a good prompt to check yours
- You are buying or selling a home and want a documented result, not a guess
- An existing mitigation fan has stopped, gotten loud, or the system monitor shows a problem
If any of that sounds familiar, a call or a form message is the right next step — tell us what you are seeing and we will talk through what to check first.

Radon mitigation systems
Sub-slab depressurization: a quiet fan and pipe system that pulls radon from beneath the home and vents it safely above the roofline.
Mitigation for slabs, crawl spaces & basements
Different foundations need different approaches, from a single suction point to sealing and covering a crawl space.
Post-mitigation retesting
Testing again after a system goes in, to confirm the level actually dropped — not just assuming it did.
System checks & fan replacement
Checking an existing system, replacing a failed fan, and making sure the vent and seals are still doing their job.
Real estate & pre-purchase testing
Testing on a timeline that works for a sale, with clear documentation of the method and the result.
How it works
- Tell us what is going on. Call or send the form below with what you are seeing, where, and how long it has been happening.
- We take a proper look. We assess the system in person, take photos where it helps, and explain what we found in plain language.
- You get a clear plan. What needs doing now, what can wait, and what it will involve — before any work starts.
What this kind of work looks like

Tips & tricks from the trade
Stuff worth knowing whether you hire us or not — the kind of things that save homeowners money and headaches when they are caught early.
Test first, worry second
Radon is common enough that testing is just sensible housekeeping, like checking a smoke alarm. Most homes test low, and the ones that do not can usually be fixed with a straightforward system.
Test where you actually live
Test on the lowest level you use regularly — a basement bedroom counts, a storage-only basement is still worth testing, but the number that matters most is where people spend time.
Follow closed-house conditions for short tests
For a short-term test, keep windows closed and avoid unusual ventilation for the test period, except for normal coming and going. That gives a result you can compare honestly.
One short test is a start, not the whole story
Radon levels move with weather, seasons, and how the house is used. A high short-term result deserves a follow-up test. A low result is reassuring, but retesting every few years, or after major changes, is smart.
Know the number that matters
The EPA uses 4 picocuries per liter (pCi/L) as the action level — at or above that, mitigation is recommended. Below that, the risk is lower, and many homeowners still choose to reduce it further. We will explain your number, not just hand you a lab sheet.
Mitigation is quieter than people expect
A typical system is a pipe and a small fan, usually outside, that runs continuously and draws radon from under the slab. Most homeowners forget it is there until the retest comes back.
Retest after mitigation, always
A system should be proven by a test, not just by the fact that a fan is running. If the level has not dropped enough, the system needs adjusting — and you should know that, not assume it worked.
Questions people actually ask
What is radon, in plain terms?
Radon is a naturally occurring gas that comes from soil and rock breaking down. It is invisible and odorless, and it can seep into a home through cracks and gaps in the foundation. It is the reason testing exists — you cannot see, smell, or feel it.
How is a test done?
A small device or canister is placed in the home for a set period — a few days for a short-term test, months for a long-term one. It is then read or sent to a lab, and you get a number in picocuries per liter (pCi/L).
What level should worry me?
The EPA action level is 4 pCi/L — at that level or above, mitigation is recommended. Levels below that still carry some risk, and the decision to mitigate is yours, with the number in front of you.
How does mitigation actually work?
Most often, a pipe is run through the slab to a fan that pulls air — and radon — from beneath the home and vents it above the roof, where it disperses. Sealing major entry points helps the system work better, but sealing alone rarely solves a high level.
Will mitigation change my house?
Visually, very little: a pipe, usually on the outside of the house, and a small fan. Inside, you should notice nothing except, hopefully, a much lower test result. The system runs continuously and uses about as much power as a light bulb.
