Radon Is the #1 Cause of Lung Cancer in Non-Smokers. Most Homes Have Never Been Tested.
Radon is an invisible, odorless radioactive gas that seeps into homes from the ground. The EPA estimates 1 in 15 American homes has elevated levels. NRPP-certified testing is the only way to know your home's status.
What Is Radon?
A Radioactive Gas You Can't Detect Without Professional Testing.
Radon is produced by the natural decay of uranium in soil, rock, and water. It enters your home through cracks in the foundation, gaps around pipes, sump pits, and construction joints. Once inside, it accumulates in enclosed spaces — especially lower levels — and your family breathes it in with every breath.

Local Risk
"We're in California — Radon Isn't a Problem Here."
That's a common misconception. While Orange County is classified as EPA Zone 3 (lower potential), individual homes can and do test above the EPA action level. Radon levels vary block by block, house by house. Soil composition, foundation type, ventilation patterns, and even recent construction can all elevate radon concentrations in your specific home.
The only way to know your home's radon level is to test it. Period. Zone maps tell you about geology — not about your family's exposure.

Slab-on-grade homes are not immune
Remodels and additions can change radon pathways
New construction can trap radon more effectively than older homes
Coastal proximity does not eliminate risk

Entry Points
How Radon Gets Into Your Home
Radon is driven into your home by pressure differentials between the soil and your living space. Your home acts like a vacuum — pulling soil gas upward through every available pathway.
Foundation Cracks
Even hairline cracks in concrete slabs or basement walls create pathways for radon gas to enter from the soil beneath.
Pipe Penetrations
Gaps around plumbing, electrical, and HVAC penetrations through the foundation are common entry points.
Construction Joints
Where walls meet the floor, expansion joints, and cold joints in poured concrete allow radon to seep through.
Sump Pits & Drains
Open sump pits and floor drains connected to soil provide direct pathways for radon to enter living spaces.
Building Materials
Some granite, concrete, and stone materials can emit radon directly, though soil gas is the primary source.
Well Water
In homes with well water, radon dissolved in groundwater can be released into the air during showering and water use.
Why It Matters
Knowledge Is Protection. Here's What Smart Parents Know.
Children breathe faster than adults and their lungs are still developing, which means indoor air quality matters even more for young families. The EPA classifies radon as a Group A carcinogen, and exposure is cumulative over time. The good news: testing is simple, and mitigation is highly effective.
The EPA and the Surgeon General recommend testing every home below the third floor. A professional radon test gives you the data to make informed decisions about your family's environment — and if levels are elevated, proven mitigation systems can reduce them by up to 99%.
Children & Infants
Higher respiration rates and developing lungs mean air quality has an outsized impact on young children — another reason testing matters.
Cumulative Exposure
Radon exposure is cumulative over time, which is why the EPA recommends proactive testing. Early detection means early action.
Combined Exposure Factors
EPA research shows radon exposure combined with tobacco smoke has a compounding effect. Testing gives you the data to make informed decisions.
Preventable
Unlike many environmental risks, radon exposure is entirely preventable with proper testing and mitigation.
Our Process
How We Test Your Home for Radon
No guesswork. No cheap mail-in kits. NRPP-certified professionals using continuous monitoring equipment that gives you real data — not a single-point snapshot.
Initial Consultation
We discuss your home's construction type, age, foundation, and any concerns. We explain exactly what we'll test, how we'll test it, and what the results will tell you.
Continuous Radon Monitoring
We deploy NRPP-approved continuous radon monitors (CRMs) in the lowest livable area of your home. Unlike charcoal canisters, CRMs provide hourly readings so we can see patterns — not just averages.
48-Hour Minimum Test
The monitor runs for a minimum of 48 hours under closed-house conditions. This gives us a statistically reliable short-term reading that accounts for natural fluctuations in radon levels.
Data Analysis & Report
We analyze the hourly data, calculate the average concentration, and deliver a clear report with your results, EPA/WHO comparisons, and specific recommendations if action is needed.
Mitigation Planning (If Needed)
If your levels exceed 4 pCi/L (or 2.7 pCi/L by WHO standards), we design a mitigation strategy — typically sub-slab depressurization — tailored to your home's construction and soil conditions.

If Action Is Needed
Radon Mitigation That Actually Works
If your home tests above the EPA action level, mitigation is straightforward and highly effective. Most systems reduce radon levels by 80–99%.
Sub-Slab Depressurization
The gold standard. A pipe and fan system creates negative pressure beneath your foundation, pulling radon from the soil before it enters your home. Works on slab-on-grade, basement, and crawlspace foundations.
Sealing & Caulking
Sealing cracks, joints, and penetrations in the foundation reduces radon entry points. While sealing alone rarely solves the problem, it improves the effectiveness of active depressurization systems.
Ventilation Enhancement
In some cases, improving ventilation in crawlspaces or lower levels can reduce radon accumulation. This is typically combined with active systems for maximum effectiveness.
