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.

Seasonal Considerations for Maui

Year-round salt air corrosion cleaning on coastal properties
2
Mold and mildew on north-shore and windward properties year-round
3
Post-trade-wind debris and plant material cleanup
4

Radon Mitigation FAQ for Maui Homeowners

How often should Maui homeowners get radon mitigation?
Given Maui's extreme microclimates: kihei averages 9 inches of rain, haiku averages 80+ inches, most homeowners benefit from radon mitigation at least once a year. Year-round salt air corrosion cleaning on coastal properties often makes spring or fall the optimal time to schedule service.
What home types in Maui most need radon mitigation?
Plantation-style homes throughout upcountry Maui and Luxury oceanfront homes and condos in Wailea and Kapalua are the most common home types in Maui 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.
