What to ask, and why
Will treatment fix my holding-tank smell?
Not if the cause is a seal, vent, or plumbing problem. That needs an RV technician first; lingering odor can be treated afterward.
Mice got into the RV over winter. Can the smell come out?
Usually. Nests and droppings are typically removed, affected materials treated, and the interior treated as a whole. Sealing entry points prevents a repeat.
Will chemicals damage my upholstery?
Ask which products touch which surfaces. Also ask whether ozone will be used; it can crack rubber seals and vinyl.
Will a provider come to my storage lot?
Some will. Ask about logistics and whether the lot allows the work; arrangements vary.
Should I get a quote first?
Yes. Ask for a written quote after the rig is assessed and before any treatment.
