★★★★★ South Florida's Top-Rated Home Inspector
Radon is the second leading cause of lung cancer in the U.S. — odorless, invisible, and completely undetectable without a test. The only way to know is to test.
EPA-Approved Radon Testing
Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil and rock. It enters homes through foundation cracks, slab openings, and construction joints — and it accumulates in indoor air without any smell, taste, or visible sign. The EPA estimates radon causes approximately 21,000 lung cancer deaths in the United States every year, making it the second leading cause after cigarette smoke.
TruView's radon inspections deploy EPA-approved testing devices at the lowest livable level of your home, collect them after the required test period, and send them to an accredited laboratory for analysis. You receive a written report with your pCi/L results and EPA guidance on next steps — and if levels are elevated, TruView provides referrals to licensed Florida radon mitigation contractors.

Complete Testing Process
EPA-approved charcoal canister or electret ion chamber placed at the lowest livable level of the home — typically the ground floor or first occupied floor — in the location most likely to have the highest radon concentration.
Testing requires closed-house conditions — windows and exterior doors kept closed except for normal entry and exit — for 12 hours before and during the 48–96-hour test period. TruView advises on protocol at scheduling.
After the test period, TruView collects the device and immediately ships it to the accredited laboratory. Lab results are typically returned within 24–48 hours of receipt.
All radon samples are processed by an EPA-approved accredited laboratory. Results are reported in picocuries per liter (pCi/L) — the standard unit used by the EPA and Florida health guidelines.
Your complete radon test report includes your pCi/L result, the EPA action level comparison, and clear guidance on next steps based on your result — including when mitigation is recommended.
If your result is at or above the EPA action level of 4 pCi/L, TruView provides referrals to licensed Florida radon mitigation contractors. After mitigation, a follow-up test confirms the system is effective.
Testing Coverage
Device placed at the lowest regularly occupied area of the home — ground floor, first floor, or any basement-level living space where occupant exposure would be highest.
Multi-story homes may require testing on multiple levels. Additional device placements available for complete characterization of radon concentrations throughout the home.
TruView uses charcoal canisters or electret ion chambers depending on test conditions — both are EPA-recognized short-term testing methods with accredited lab analysis.
Short-term tests require 48–96 hours under closed-house conditions. This timeline is compatible with standard real estate inspection periods and new construction closeouts.
Radon testing requires windows and exterior doors closed (except normal entry/exit) for 12 hours before and during the test. TruView coordinates proper conditions with sellers and listing agents at scheduling.
All devices are shipped directly from the property to the accredited lab with documentation of test period, placement location, and collection date — ensuring results are defensible for transaction purposes.

Florida Radon Risk
Florida's radon risk is often underestimated. While lower than high-risk northern states, elevated radon levels occur throughout Florida — and the EPA recommends testing in all regions regardless of perceived risk.
Central Florida — particularly Orange, Osceola, Polk, and Hillsborough counties — has the highest radon potential in the state due to phosphate-rich soils and underlying geology. The FDOH (Florida Department of Health) identifies Central Florida as a Zone 2 radon area, meaning average indoor levels are predicted to be 2–4 pCi/L. Properties in and around Orlando, Kissimmee, and Sanford should be tested as a standard part of pre-purchase due diligence.
Many buyers assume new construction homes are safe from radon — this is incorrect. Radon enters through the slab, and a new slab has the same potential for radon entry as an older one. Florida building code (Florida Radon Protection Requirements, F.S. 553.98) requires radon-resistant new construction features in certain counties, but these features reduce risk, not eliminate it. New construction homes in Central Florida should be tested before occupancy.
Florida's energy-efficient, impact-resistant, and hurricane-code construction often produces tightly sealed homes with limited natural air exchange. While this is excellent for energy efficiency and storm resistance, it can allow radon to accumulate to higher concentrations than in older, leakier construction. Homes built to Florida's post-2000 building codes with high-efficiency impact windows and continuous AC operation are more likely to accumulate radon if it enters from the slab.
In Florida real estate transactions, radon testing is not universally required — but it is increasingly requested by buyers' agents, particularly in Central Florida. TruView's radon tests are conducted using chain-of-custody protocols that make results defensible in transaction negotiations. If testing reveals elevated levels, a mitigation system typically costs $800–$2,500 and reduces levels by 50–99% — a small cost relative to the health risk and the transaction value.

Learn More →"We were buying a new construction home in Orlando and our agent recommended adding radon testing. I honestly didn't think it was necessary for a brand new house. TruView came back at 5.2 pCi/L — above the EPA action level. Builder installed a mitigation system before closing and post-test came back at 0.8. Glad we tested."
"TruView handled everything — placed the device during the home inspection and picked it up 48 hours later. The written report was clear and the EPA comparison was easy to understand. We came back at 1.2 pCi/L — well below the action level — and had complete documentation for the transaction file."
"As a buyer's agent in the Orlando market I include radon testing in every offer I write for ground-floor or single-story properties. TruView is fast, professional, and their lab turnaround is quick enough to work within standard inspection windows. Never had a problem with the reports being accepted."
Common Questions
Radon is a naturally occurring radioactive gas produced by the decay of uranium in soil and rock. It is odorless, colorless, and tasteless — completely undetectable without a test. Radon is the second leading cause of lung cancer in the U.S., causing approximately 21,000 deaths per year. It enters homes through foundation cracks and slab penetrations and accumulates in indoor air.
South Florida's overall risk is lower than northern states, but elevated levels occur throughout Florida — particularly in Central Florida (Orange, Osceola, Polk counties) where phosphate-rich soils increase radon production. The EPA recommends testing everywhere because individual properties can exceed the 4 pCi/L action level even in lower-risk areas.
TruView deploys EPA-approved testing devices at the lowest livable level for 48–96 hours under closed-house conditions. Devices are sent to an accredited lab for analysis. Results typically return within 24–48 hours and TruView delivers your written report as soon as they're available.
The EPA action level is 4 pCi/L. At or above this level, mitigation is recommended. The U.S. average indoor level is 1.3 pCi/L. Between 2–4 pCi/L, the EPA suggests considering mitigation. There is no completely safe level, but risk decreases as levels decrease.
At or above 4 pCi/L, the EPA recommends a radon mitigation system — typically sub-slab depressurization, costing $800–$2,500. These systems typically reduce levels by 50–99%. A post-mitigation test confirms effectiveness. TruView provides referrals to licensed Florida radon mitigation contractors.
No. New slabs have the same radon entry potential as older ones. Florida building code requires radon-resistant features in certain counties, but these reduce risk without eliminating it. New construction homes in Central Florida should be tested before occupancy.
Add-on to a home inspection: $100–$150. Standalone radon test: $125–$175. Post-mitigation clearance test: $100–$150. All pricing includes device placement, collection, accredited lab analysis, and written report.
TruView provides radon testing in all five regions — particularly recommended for Central Florida properties on slab foundations.
