Caravan Damp Test The Ultimate Guide. 

Hi Mark awesome vlog once again thanks👏🏻 It was myself who won the Extech MO55 damp meter when you all done the competition on the Halloween special of the motorhome show. I've got to honest it is a superb bit of kit and well worth the money for ordinary caravaners/motor homers like myself. I had my caravan serviced by the main dealer where I bought it. It was Lunar which didn't have the manufacturer warranty when I bought it as they had just gone bust, but this meter proved its worth as it found a slight reading of damp on the front left side near the roof strap, which was then dealt with by the dealer and re-sealed before it got out of hand and expensive for me to deal with. In fact due to this I spoke with the dealer and negotiated to a have the whole van re-sealed under their warranty and I paid a small labour charge which I didn't mind doing as at least I knew it was done properly. Since this I use a mobile technician, who is absolutely amazing, and the meter gave me a heads up on a potential issue before hand, so at least I could tell hime before hand. So when he came to do my annual service on the drive he also dealt with the issue of the higher reading at the same time as he then had factored in the time to deal with it on the day. Great bit of Kit well worth the money👍🏻

That's very useful. Thank you Mark ! Good to see how honest and thorough you are as a dealer. Some years ago we bought a used c'van from a main dealer here in the NW. In the washroom not just damp but rot had been hidden with fresh matching wall boards...😳 We fixed it ourselves at a cost but once bitten twice shy !

A very good video Mark... honest and very helpful as ever......we really must come along and see your place again ..... cheers 'The Camp Caravanners'

Hello Mark, bought the protimeter because of your video. I’ve got two questions and hope you’re willing to answer them: 1) sometimes the back section and very often the pins don’t seem to measure at all. Is this because the material is to dry? 2) my van is new from the factory. I’ve got two 20 ish readings. The pins don’t measure at all at those spots. Can I assume that it’s a false reading and probably some metal in the wall? Thanks a lot!

Hi Mark. Very informative video. What setting would you recommend for a 2017 Bailey on the Extech. Thinking of getting one as a service picked up possible damp starting around the toilet. As you say, maybe environmental factors at play there. I'm wondering as there isn't wood in the caravans construction. Unless the floor is some sort of wood. Many thanks.

Hi, could you please tell me the make & name of the damp meter you use.

Is that cheaper damp meter worth getting or is there better for same price.

Hi Mark, if the meter shows no reading at all does this mean it is full of water?

Hi. Mark. What about caravans that are GRP outside and inside? I believe our dealer just checks the floors on these models.

Would I be correct in saying below 20% is acceptable, also I have a Swift elegance 2015 is it right that these do not have any wood in the build including the floor.

Hi Mark, just had my caravan serviced and it showed 22% damp between 2 of the front windows. They've recommended a retest in 3 months but this goes against their policy and is more inline with 15 to 20% damp. Having had a damp disaster with a bailey in the past, this is my worst nightmare. What do you reckon? Should I insist it's looked at again? It's still under warranty.

Excellent video as usual. Regarding newer carans with modern building techniques, do you find any particular make of caravan worse than others? We have a 2019 Bailey Phoenix, I would love to see how you would carry out a damp test on one.

Hi mark so my question is if the prongs give you a reading of let’s say 15 but the non invasive gives a reading of 50 to 60 what’s does this mean ?

Hi what damp meter do u recomend as there so many out there

If I get a high reading, find the leak and seal it, would that be ok?

Hi Mark , we have a Bailey Cadiz 2015 S3 and have found damp on both rear underside corners about an inch in from the edge. It’s ‘softish ‘ but seems to be drying out. What would you recommend to treat this ? Thanks

What readings are high and low

Could you tell me what sealant you recommend for this thanks

Bought an extech dual prong and scanner MO55 not sure which setting for scan is it wood or building materials" plasterboard,concrete etc" it has pins..wood or building materials or scan wood or building materials....also if checking floor from underneath do I use wood or building materials BUILDING MATERIALS SAYS..WALL BOARDS,SHEETROCK,CARDBOARD,PLASTER,CONCRETE,MORTAR. SORRY I'M CONFUSED...regards Ian

Hi Mark If a pinless damp !eter had density settings 1 - 10 which setting would you recommend putting it on when testing caravan

If u find damp how is it fixed? Thanks

Just for your reference Never slide damp meter over the testing surface!!! Readings won’t be accurate Please read protimeter instructions 😂👍
