Damp. It’s the one word that can wipe thousands off the value of your motorhome overnight. In Episode 8 of The UK Motorhome Market Show, we are diving deep into the “Silent Killer” of motorhome value.
We explain the difference between condensation and true water ingress, why the UK’s climate makes regular checks essential, and how the industry-standard Habitation Check works. Plus, we show you the tools of the trade—including the Protimeter SurveyMaster—and break down the damp reading percentages that every owner needs to know.
In this episode:
Condensation vs. Ingress: Why your damp reading might not be as scary as you think.
The £10,000 Repair: A look at how structural damp can lead to 100+ hours of labor.
The Pro’s Toolkit: How to use a damp meter correctly and where to look for failures.
