I have a 2016 Bailey motorhome, I am in the marine industry so I do my own damp checks & I also know a little about the ingress of water. I have damp at the rear of the vehicle, underneath the gas locker and underneath the water tank, this is on the wooden floor. Having investigated the issue further I can see that the edges of the wooden floor have not been sealed, so the edge is basically "raw" - the water is getting in when driving on wet roads and through puddles from up and under. The rear panel housing the lights is not watertight & water is running down the rear of the vehicle & through a gap straight to the wooden floor. In my opinion this is a build fault which could easily be rectified using a composite floor or at the very least sealing the edges of the floor.
I have a shipwright coming over to help me , my damp is not too serious, so we're going to remove the rear bumper to access the edges of the wooden floor and seal all this with resin.@@MotorhomeMatt We may remove the water tank and gas locker to see how bad it is, if the wood isn't rotten/soft we'll seal it properly rather than replace.
Hi guys… talking about the seals getting old is there anyone around that replaces all your seals that you know about? Thanks for the time you put into helping others out with your knowledge and experience it’s priceless thank you 🙏 😊
Thanks for watching and for your kind words Claire. The seals are usually just a bead of sealant which most body shops, caravan or motorhome service centres or mobile habitation engineers can apply. The key is to remove the old sealant, clean really well then reseal. Google NCC Approved Workshop Scheme for businesses near you.
My 1st motorhome was tested and deemed to have damp around all the skylights. I let a dealership repair it . After the next rain there was an enormous pool on the roof , l can only assume they climed on the roof causing the aluminium to bow . I now have a self built van with nothing cut into roof
My Hymer has a flat roof and also pools water when it rains - if the vehicle is level. I am thinking this is to be expected with a flat roof, but I am sure the design of the vehicle allows for roof maintenance by allowing for climbing onto it. I would be surprised if manufacturers didn’t allow for this.
@@TheIrishMegaphone Pooling on a roof can be common depending on the material its built from. Walking on a roof however should not be deemed safe or possible without knowing the what and how its constructed. Van conversions will dent very easily. Equally an older motorhome with timber construction can be prone to 'knee' or 'foot' damage. Thanks for your comments and for listening in!
I firmly believe a roof timber was broken by the dealership ( no longer trading) . I was able to push it back into place from the inside and brace it . I would never climb onto a roof unless it was described as a walk on roof . Have seen self builders on ytube posing on their roofs and then wondering what caused them to leak
@@vincentzielinski7157 yes. I will definitely do some research about my Hymer’s roof. I probably will email them. It would be good to know. It’s an SL aluminium model 2008.

Also thinking of buying first motorhome, so super grateful for Matts question

That’s a common problem on many models using this build technique. It’s also quite involved to repair!

@@MotorhomeMatt Thanks for that tip. I must look in to that regarding my own motorhome and see whether it is possible. I’ve never been on the roof.
