Radon only, and it shows.

The brief

Teaching an invisible problem without scaring anyone

Excalibur does one thing. In a market where most radon work gets sold as a sideline, that focus is the whole competitive argument, but it only counts if a visitor can tell the difference immediately.

The subject itself is the harder problem. Radon is invisible, the units mean nothing to a homeowner, and the honest version of the pitch involves lung cancer numbers. Lean too hard on that and it reads like a scare ad. Leave it out and nobody has a reason to act today.

The design

Education as the conversion path

A stat band anchors the four numbers that actually mean something, and a cutaway diagram does more work than three paragraphs would.
