Damp (caravan damp report) is the biggest misconception in the caravan industry. It strikes fear into the hearts and minds of pretty much every caravan owner.
Lets get this straight, not all water ingress or damp is going to end up with the inside of your caravan being dismantled or costing you thousands of pounds. 95% of all cases which we see are easily rectified and relatively inexpensive.
Another misconception is that you can smell damp, again this is not the case, you can only smell damp if the wood behind has rotted which only takes place over many years of water ingress. There are a number of different stages, all of which has a different cost of repair.
Stage 1: At this point any ingress/damp is not visible and can only be detected using a moisture meter. During this sage only a reseal is required, most commonly windows or awnings rails. This is most likely in caravans, new and old.
Stage 2: This stage usually occurs when the owner has missed a service or two. It is quite possible that it is visible under the window rubber or there is pimpling on the wallboard. It may also not be visible and depends on the location. Method of repair will include resealing the area which is causing the leak ie window, awning rail, roof light and may also require some wallboard to be stripped and replaced. This can be expensive but should last a good few years.
Stage 3: This stage is why caravan owners are terrified of the word ‘DAMP’. It may well be noticeable by smell, the walls could be soft to touch and it will certainly be visible either by pimpling or water marks. The walls could also be unstable due to the rotten wood behind. The cause is neglect, due to lack of servicing and proper maintenance. Most cases which are at this stage are beyond economic repair.
A Annual Full Caravan Service and Habitation Service includes a full damp report, should highlight any areas that may need attention. Please speak to the engineer at the time of the service for further details.

Readings between 15 - 20% may require further investigation when compared with the average of all readings taken.
Consideration should be given to re-checking the area in three months.
Readings greater than 20% will identify areas needing remedial work.
There may be early signs of water ingress or evidence of moisture.
Again, consideration should be given to re-checking the area in three months.
When readings go above 30% structural damage may be occurring and deterioration is inevitable.
Water Ingress, the awning rail had been over sealed. A breakdown of sealant, a hole in the join.
