Radon Testing in Syracuse, NY

The only way to know your home’s radon level is to test. Because Onondaga County is an EPA Radon Zone 1 area — the highest-risk designation — every home in the Syracuse region should be tested, regardless of age, foundation type, or whether a neighbor’s home tested low. Radon is invisible, odorless, and varies house to house. Certified professionals who provide fast, accurate radon testing across Syracuse and the surrounding towns.

How Radon Testing Works

We use continuous radon monitors (CRMs) for fast, tamper-resistant results — typically within 48 hours — rather than slower passive charcoal kits that leave more room for error. The monitor is placed in the lowest livable level of your home under closed-house conditions, and it records radon levels hour by hour, giving you a reliable, professional-grade reading.

Once testing is complete, you receive certified results showing your home’s average radon level. If the result is at or above the EPA action level of 4.0 pCi/L, we’ll walk you through your mitigation options. If it’s below, you have documented peace of mind.

How Our Radon Process Works

When You Should Test for Radon

Testing is especially important in two situations. First, any Onondaga County home that hasn’t been tested in the last few years — radon levels can change over time as a home settles or as seasons change. Second, any home being bought or sold in New York, where radon is addressed on the state’s Property Condition Disclosure Statement. Buyers frequently request a radon test during the inspection period, and testing before you list removes a common last-minute surprise.

Frequently Asked Questions

How long does a radon test take?
A short-term test with a continuous radon monitor typically takes about 48 hours under closed-house conditions, followed by certified results.

Do I need to leave my house during the test?
No, but you’ll be asked to keep windows and exterior doors closed as much as possible during the test (closed-house conditions) so the reading is accurate.

What if my radon level is high?
If your home tests at or above 4.0 pCi/L, a mitigation system will bring it down. We can explain your options and provide an estimate.
