Does buildings insurance pay for mould in Germany?
In short
Does buildings insurance pay for mould in Germany? Only if an insured event caused it, usually a burst pipe. The mould removal is then normally part of the pipe water claim. Mould from condensation, poor ventilation, building defects or rain getting in is not an insured event. Mould remediation usually costs EUR 1,500 to 5,000.
What mould reports and mould remediation cost in Germany, based on published price examples, 2026.
Example
Typical range
Mould report, small scope
about EUR 200 to 400
Full report with search for the cause
about EUR 500 to 1,200
Disinfection by a specialist, average infestation
about EUR 1,000 to 4,000
Mould remediation in total, report and treatment
usually EUR 1,500 to 5,000
Complex case with badly fitted insulation
around EUR 13,100

Worked example
Detached house, leaking pipe behind the bathroom wall, mould found after weeks
How the claim adds up when the mould results from insured pipe water damage.
Leak detection
about EUR 200 to 600
Drying, area up to 20 square metres
about EUR 400 to 800
Mould remediation with report
about EUR 2,500
Opening the wall, new pipe, tiles
about EUR 2,000
Excess, if agreed
for example EUR 500
Around EUR 5,000 to 6,000 of damage, paid by buildings insurance minus the excess. If the mould had come from condensation, you would bear the full amount.
When buildings insurance pays for mould
Buildings insurance (Wohngebäudeversicherung) does not pay for mould as such, but for damage from insured perils such as pipe water, storm or fire. If a pipe bursts inside a wall and the damp goes unnoticed, mould grows. The mould is then a consequence of the pipe water damage and is normally settled together with leak detection, drying and repair.
So the cause of the moisture is what counts. Have a specialist establish it before the mould is removed, and take photos. Without a proven insured cause, the insurer will reject the mould claim.
Mould, dry rot and wood decay
The German model terms exclude damage from dry rot (Schwamm) and all kinds of wood decay fungi in the pipe water section. This means wood destroying fungi such as true dry rot, not the usual mould on walls or ceilings. Mould resulting from a burst pipe is therefore not caught by this exclusion.
Some policies deviate and limit or exclude mould expressly, others list mould removal as a benefit. Read the exclusions of your policy before reporting mould damage.
Mould without an insured cause
A lot of mould grows without any insured event: condensation on cold outside walls, too little ventilation, thermal bridges or moisture coming through masonry and basement. No buildings insurance pays for that, because rain and groundwater are excluded from the pipe water cover.
Cause of the mould
Buildings insurance
Who else pays
Burst pipe in a wall or floor
normally yes, as a result of the pipe water damage
neighbours' liability cover if they are at fault
Leaking silicone joint in the bathroom
no, not pipe water according to case law
the owner, for a new bathroom the tradesperson
Condensation from ventilation and heating
no
whoever caused it, owner or tenant
Building defect, missing sealing
no
builder or developer under the warranty
Rain through a roof damaged by storm
yes, as a result of the storm damage
contents insurance for furniture
Damp basement from groundwater
no, only via natural hazards cover depending on terms

Tenants, landlords and mould
In a rented flat, tenancy law decides who removes the mould, not insurance. The landlord must keep the flat in a condition fit for use (section 535 Civil Code). If mould limits the use of the flat, the tenant may reduce the rent (section 536 Civil Code).
Tenants are not liable for wear caused by normal use (section 538 Civil Code). If they caused the mould themselves through poor ventilation, the landlord can claim compensation. A report on the building fabric and the way the flat was used is then often needed.
Why quick drying decides whether mould is paid
After an insured water damage you must prevent and reduce the loss as far as possible (section 82 Insurance Contract Act). If you delay drying for weeks, you risk a cut for the mould that grows as a result. Report the damage at once and start ventilating and drying without destroying the evidence.
The figures show how expensive damp can get: pipe water claims cost German buildings insurers around EUR 4.9 billion in 2024, more than half of all residential building claims. Every day the wall stays wet gives the mould more time.
Step by step
Have the source of the moisture found before removing the mould.
Photograph the mould, wet areas and surroundings.
If a pipe may be leaking, tell your buildings insurer or landlord at once.
Start drying and stop using the room if necessary.
Send reports and quotes to the insurer before remediation.
For condensation, change heating and ventilation and fix the cause for good.

Questions and answers
Frequently asked
Does contents insurance pay for mould?
For furniture and clothes only if an insured event such as pipe water caused it.
It does not pay for ventilation mould either.
Is mould after a burst pipe always covered?
Normally yes as consequential damage.
Some terms limit mould, and the insurer can cut the payment if drying was delayed.
Who pays for mould in a rented flat?
It depends on the cause: the landlord for building defects,
the tenant if poor ventilation is proven.
Buildings insurance only for an insured cause.
What is the difference between mould and dry rot?
Dry rot (Echter Hausschwamm) destroys wood and is excluded.
Mould on walls is a different fungus.
Does natural hazards cover pay for mould after a flood?
If your policy includes flooding, mould resulting from the flood may be included,
