Mould Remediation: Costs, Process and Who Pays

What mould remediation costs

Professional mould remediation in Germany typically costs between 300 and 15,000 euros,

depending on how far the growth has spread. The growth itself is rarely the large item.

The cost sits underneath it: stopping the moisture, removing the affected layers and

rebuilding what was taken out.

Why published prices vary so much

Search for a square metre price and you will find anything from about 10 to 500 euros.

That is not the trades being inconsistent, it is the same word covering very different

work. Surface treatment of a small dry patch sits at the bottom. Proper remediation

behind a sealed containment runs in the order of 120 to 160 euros per square metre.

Deep growth with removal of the affected build-up is quoted at 200 to 500 euros per

square metre. None of those figures include fixing the cause, which is a trade of its

own.

Where do-it-yourself ends

The German Environment Agency draws the line at area and depth: small growth, as an

example under half a square metre and only on the surface, can be removed by a

layperson. That figure is explicitly an example, not a rule. Do not do it yourself if

you are allergic to mould, have a chronic respiratory illness or a weakened immune

system. The moisture cause has to be found and removed in every case, or the growth

returns. Disinfectants are generally unnecessary, and firms that fight mould with

nothing else are rated as unreliable by the agency.

Berlin building stock

Much of Berlin sits on sand with a regionally high water table, and many pre-war

cellars have no continuous damp course. Damp cellar walls here are often the state of

the building rather than a usage error. Where a refurbishment is happening anyway, it

is worth clearing the growth during the gutting works.
