Home Inspection vs. Radon/Mold Testing: What's the Difference?

A general home inspection covers a home's overall structure and systems — roof, foundation, electrical, plumbing, HVAC, and similar components — through a visual, walkthrough-based assessment performed by a licensed home inspector. It's a broad, foundational check meant to surface major issues across the whole property.

How Radon and Mold Testing Are Different

Radon and mold testing are different in kind, not just in scope.

Radon testing requires specialized electronic monitoring equipment left in place for 48 hours — it's not something that can be assessed visually during a walkthrough, since radon has no visible or detectable presence at all.

Mold testing similarly requires physical air and surface samples analyzed by an accredited laboratory — a level of specificity a general visual inspection doesn't provide.

Are Radon and Mold Testing Included in a Home Inspection?

Some general home inspectors do offer radon or mold testing as an add-on service, and some don't offer either at all — it varies by inspector and market.

When a home inspection includes a radon or mold add-on, it's worth understanding whether that add-on is performed by an appropriately licensed radon professional or accredited lab process, versus a more basic visual check that doesn't carry the same reliability as dedicated testing.

A Specialized Testing Approach

DezAir focuses specifically on radon and mold testing — we don't perform general home inspections — which means our process is built entirely around getting an accurate, documented answer for those two specific concerns, rather than folding them into a broader walkthrough.
