Intense tropical UV year-round (UV Index 10–11 common at elevation)
Occasional seismic activity and ashfall from volcanic eruptions
Common Home Types We Service
Single-story ranch homes in Kona subdivisionsOlder plantation-era homes in Hilo and PunaCustom homes on large agricultural lots in North Kohala and WaimeaNewer homes in Waikoloa Village and resort communitiesOff-grid and self-sufficient homes in rural Puna and Ka'u

What You Get

Reduces radon levels by 90–99%
Most systems installed in one day
Sub-slab depressurization — proven, EPA-recommended method
Quiet operation — most homeowners don't notice the system
Post-mitigation testing included to verify effectiveness
System lifespan of 20+ years with minimal maintenance

Our Radon Mitigation Process

01

Radon Testing

If you don't have recent test results, we conduct or recommend short-term (48-hour) or long-term testing before and after mitigation.

02

Diagnostic Testing

We perform suction/pressure field extension tests to determine the best system placement and pipe routing.

03

System Installation

A PVC pipe is installed through the floor slab (or membrane) and connected to a continuously running fan that draws radon from beneath the home and exhausts it above the roofline.

04

Post-Mitigation Test

A follow-up radon test confirms the system is achieving adequate reduction — typically to below 2.0 pCi/L.

Radon Mitigation FAQ for Big Island Homeowners

How often should Big Island homeowners get radon mitigation?
Given Big Island's active volcanic activity producing vog (volcanic smog) across kona and ka'u districts, most homeowners benefit from radon mitigation at least once a year. Year-round vog cleaning of surfaces on the Kona and Ka'u sides often makes spring or fall the optimal time to schedule service.
What home types in Big Island most need radon mitigation?
Single-story ranch homes in Kona subdivisions and Older plantation-era homes in Hilo and Puna are the most common home types in Big Island and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
What radon level requires mitigation?
The EPA recommends mitigation at levels of 4 pCi/L or higher. Consider mitigation at 2–4 pCi/L as there is no truly safe level of radon exposure.
How much does radon mitigation cost?
Most residential mitigation systems cost $800–$2,500 installed, depending on house construction and foundation type. This one-time cost provides lifetime protection.
How does a radon mitigation system work?
Sub-slab depressurization (SSD) is the most common method — a fan creates negative pressure beneath the slab that draws radon away from the home before it can enter, exhausting it harmlessly above the roofline.
Will a mitigation system affect my heating and cooling bills?
Sub-slab depressurization removes a small amount of air from beneath the slab, not from inside the home. The impact on energy costs is negligible.
