A clear path.
From the start.

From your free assessment to follow-up measurements: we guide you through every step, with a clear quotation and written guarantees.

Our process.
One step at a time.

Assess

We visit your property and establish where the moisture comes from. Your personal on-site assessment is free and non-binding.

Plan

Together, we discuss the right solution for your building. You receive a written quotation covering device selection, the scope of work and guarantee terms.

Measuring instruments and tools for the on-site work.

Install

We install OMBRELLO and establish the measurement points. Installation requires no chemical injection, and your rooms remain usable.

Measure again

After 6 and 18 months, we measure at the same points. You receive the documented results. Both follow-up visits are included in the purchase price.
