MURSAIN
Who are we?
A family business putting its expertise at the service of one conviction: keeping French heritage alive by treating moisture at its source, never on the surface.
In brief
MURSAIN is a family business specialising in building moisture issues since 2020. Founded by Louis, Ythier and Delphine de la Guéronnière and trained directly by Jack LECARPENTIER, inventor of the process.
One family
First and foremost a family business
MURSAIN is first and foremost a family story. Louis and Delphine de la Guéronnière had this process installed in their own home by Jack and were convinced by the exceptional results.
Proven for more than 40 years, MURSAIN promotes the process developed by Jack Lecarpentier, an expert in moisture pathology and an international court expert. Our goal is not to sell one single solution for every wall, but rather to identify the issues and their causes before taking action.
That is why MURSAIN starts by analysing the causes of moisture before recommending the equipment suited to your moisture problems.
Direct transmission
Trained directly by Jack LECARPENTIER
Jack Lecarpentier, inventor of the process marketed by MURSAIN and a court expert in moisture pathology, trained the La Guéronnière family. He introduced the methods we use today to stop moisture in buildings: methods proven for more than 40 years. Today, we are their heirs and guardians.
Understand the cause before proposing the solution
We do not hide the visible effects of moisture. We go back to their origin in order to propose the most appropriate response, consistent with the building, its materials and its context.
