Does home insurance cover rising damp?

Home insurance usually does not cover rising damp. Insurers treat it as gradual damage and a maintenance issue rather than a sudden, one-off event, and gradual problems are almost always excluded. There are narrow exceptions where damp results from an insured event, but rising damp itself is normally down to the homeowner.

Why rising damp usually isn’t covered

Buildings insurance is designed for sudden, unexpected damage: a burst pipe, a storm, a fire. Rising damp develops slowly over months or years as a damp-proof course fails, so insurers class it as wear, maintenance and gradual deterioration, all of which are standard exclusions. The same logic applies to penetrating damp and condensation.

When damp might be covered

There are situations where the underlying cause is an insured event, and then the resulting damage may be covered, even if the damp itself isn’t:

Escape of water — a burst or leaking pipe that soaks a wall
Storm damage — a roof or rendering failure in a storm that lets water in
Accidental damage — if you have that optional cover and it applies

Even then, insurers typically pay to fix the cause and the damage from that event, not pre-existing damp or the long-term damp-proofing work. Always check your policy wording and speak to your insurer.

What to do if it isn’t covered

If your damp is the usual gradual kind, the cost falls to you, but it’s often less than people fear once it’s correctly diagnosed. The key steps:

Get a proper damp survey so you know exactly what you’re dealing with, not a worst-case guess.
Make sure it’s genuinely rising damp and not cheaper-to-fix condensation.
Get a fixed-price quote for the actual work needed.

Frequently asked questions

Will making a claim affect my premium?

If the damp results from an insured event and you claim, it can affect your premium and excess like any claim. For ordinary gradual damp, there’s usually nothing to claim against.

Does landlord insurance cover rising damp?

Generally no, for the same reason: it’s treated as maintenance. Landlords are responsible for keeping a property free of damp and mould.

Can I claim if damp was hidden when I bought the house?

That’s usually a matter for the seller’s disclosures or your survey, not your insurer. A specialist damp report can clarify the situation.
