DAMP.wiki is not-for-profit

We care about accurately identifying the root cause of damp every time. Once identified the cost of the remedy is normally low, sometimes taking minutes to fix. The skill is in the identification, rarely the remedy.

Do RICS surveyors work for free?

For an unbiased opinion on the cause of damp and remedy, expect to pay an independent damp surveyor. Damp proofers (builders) offer “free” or subsidised “damp surveys”. These are biased and profit motivated quotes.

30 year guarantee​

Is a damp proofer’s guarantee valuable? The catch is the guarantee is only if there is rising damp and since rising damp is exceptionally rare, these guarantees have no value.
