Hi

Been to view an Eriba Triton 1994 today. Loved it apart from some bubbling on the interior under a side window. The current owner says the window was replaced 2-3 years ago but I am concerned there is damp. Any ideas if this can be dried out/repaired and the approx cost. I have attached a picture to try to show the problem. IMG_1466.JPG - Bild entfernt (keine Rechte)

It's hard to say where the damp is coming from, however I can see from the picture that the window seal joint is at the bottom. When replacing the window seals it is advisable to put the joint at the top. The reason for this is that as the condensation collects it runs to the bottom of the window seal and then down the crack where the joint is..

The cure for it will be to take the seal off and place the joint at the top,and try and dry the board out with a hair dryer.

Other than that it could be the belly band seal on the outside has been compromised and that is a bigger job to fix.

Thank you for the reply. Seemed fine from the outside so think you might be right about the joint as all the bubbling is under the joint.

Sorry it went on side ways. It's the inside under the side window

No it's a runner for the curtains. They have been added on every windows.

That's outside nothing to do with the Eriba you can just see it through the window. It's stored in a car port type thing and it's part of that.

Looks like that warping to the hardboard panel is on the lower half behind the bench cushion, which I would say is down to bad ventilation.

There is always a tell tail sign with water ingress in hardboard, ply and timber, it will swell and deform more at the source and reduce with less deformation as the ingress gets absorbed into the material. This give you an indication of the source.
Unless the window seal is leaking with the water bypassing the top part of the internal hardboard panel, dripping or running down behind the polly insolation, then working back up the panel, only inspection would tell.
