Quick answer
Test the lowest level you regularly use, or have an inspector do it during a home purchase. EPA says to fix a home at or above 4 pCi/L and to consider fixing it from 2 to 4. For mitigation, ask for the installer’s current certification and call around early, since some crews travel over the mountains.

Radon testers and mitigators to compare
The first three are local testers, typically inspectors. The other three do mitigation and travel or may travel to Bend. All are listed alphabetically within their groups, and you should confirm that a company will serve your address.
Company details were reviewed in October and November 2026. License numbers are shown as the company publishes them or as they appeared in state records at that time. Services, staff and license status change, so confirm what matters directly and in writing.

What your number means
Radon is measured in picocuries per liter (pCi/L). EPA’s guidance:
- Below 2: EPA says reducing radon below this level is difficult. Retest every couple of years, or after big changes to the house.
- 2 to 3.9: consider a fix, since no level is risk-free. If this came from one short test, a longer test can give you a better year-round average.
- 4 to 8: you’re at or above EPA’s action level. Do a follow-up test, then fix the home if the follow-up or average of two short tests is 4 or more.
- Above 8: follow up quickly with a second short-term test rather than a long one.
Levels can move with season, weather and how the house is run. Heat, fans and blower use can all matter.
Getting an accurate test
- Test low. Place the test in the lowest level you regularly use, away from drafts, kitchens and bathrooms.
- Close up. Short-term tests need closed-house conditions, starting ahead of the test. Avoid whole-house fans.
- Buying a home? Put the test inside your inspection window and use a tamper-evident or continuous monitor. Ask the seller not to open things up. See our home inspection guide.
- Doing it yourself? Kits are inexpensive and work well if you follow the directions. The Oregon Health Authority also offers free kits to households in qualifying ZIP codes, usually ones with few test results, and updates the list each December. Check whether your ZIP currently qualifies.
How mitigation works, and hiring from a distance
A common system pulls air from under the slab or a crawl space membrane and vents it above the roof with a fan. Your house style largely decides the approach: crawl spaces, common in Bend, usually need a sealed membrane. A good contractor will explain where the fan and pipe go, how the system is monitored and how much it may cost to run.
When no certified company is local, the following checks count even more:
- Check the Oregon Health Authority’s radon pages for its current list, which may have changed.
- Ask for the installer’s NRPP or NRSB credential, and look it up.
- Verify the CCB license for the business.
- Find out what happens if the system needs adjusting: who comes back, and at whose cost?
- Require a post-install test by a third party, or at least an independent test you arrange yourself.
Cost
Test prices vary by method and how far someone has to travel. JustRadon’s posted $150 to $450 range is the clearest we found, while DIY kits cost less and inspectors often price radon as an add-on. We don’t publish a mitigation average here because we couldn’t find enough Bend pricing to make it reliable. Expect the total to depend on foundation type, the membrane area, the pipe route and travel, and get more than one written quote.
How to get comparable quotes
Ask every mitigation company to spell out the following in writing:
- Installer’s certification number and CCB number
- System type and diagnostic testing done before install
- Fan location, pipe route and where it vents
- Crawl space membrane area and how it’s sealed
- Monitoring gauge or alarm
- Electrical work, and who performs it
- Target level and post-mitigation test
- Trip charges and callback terms
- Warranty on the system and the fan
Our contractor bid comparison checklist gives you a simple way to line those details up side by side.
Red flags
- A guarantee of a specific reading with no diagnostics
- A vague answer on certification
- No retest after the install
- A pipe that vents near windows or a place people gather
- A fan placed in living space
- A decision to skip testing based on a neighbor’s result
- Pressure to mitigate after one questionable short test
Common questions
Is there a certified radon mitigation company in Bend?
The Oregon Health Authority’s certified list, as revised October 13, 2026, had no Bend or Central Oregon company. That can change, so check the current list, and verify the credentials of any company you consider.
What radon level should I fix?
EPA says to fix a home at or above 4 pCi/L and to consider fixing it from 2 to 3.9 pCi/L. It recommends follow-up testing before making a decision in most cases.
Can I get a free radon test kit in Oregon?
Possibly. The Oregon Health Authority offers free kits to households in qualifying ZIP codes, generally areas with few results, and updates the list each December.
How long does a radon test take during a home purchase?
Local inspectors here list tests of about 48 to 72 hours. Schedule early enough that results arrive before your inspection period ends.
Does a crawl space home need radon testing?
Yes. Any home type can have elevated radon, and the only way to know is to test. Crawl space homes usually need a sealed membrane if a mitigation system is installed.
