    Just had v heavy rain in Polstead ( thank you big Bertha ) and now the window by the gas hob is running with water. Anyone got any experience of this and how it might be cured ?
    My van is an Autotrail Apache 2009 with the folding / concertina type blinds

    Should clarify, it's coming out of the blind cassette and running down the wooden wall board onto the work top

    Check the sealant round the window frame. An extra bead might work.

    Had the same problem on a kontiki....no wise cracks, i loved that van.
    The water was running off the bottom of the frame and down the wall.
    It was entering at the top and running around the frame and running over the edge.

    To be safe i removed the whole window frame, cleaned off the old mastic and re-bedded the frame.....only took a couple of hours.

    No point putting more mastic on if it might rain soon.....it isnt waterproof until its cured.

    Better to dry the outer wall as best as possible and put some gaffa tape around the window frame.

    Sort it properly when the sun is out and likey to stay out for the day.

    the only way to fix it long term is do it properly as mentioned above.
    remove blind and window
    clean up old mastic
    dry out the surfaces
    treat any soft wood to prevent rot
    reassemble using the correct mastic on a tape

    never ever use silicon sealant to try and seal a leak, it wont work and will trap damp in causing rot. much much more expensive than doing it right

    Thanks for all the tips, will try a temp repair with white sealant for now ( we're on hols for 2weeks) and do it properly when we get home .
    What's the best type , brand of mastic to use for the permanent repair ?

    creeping jack and captain tolleys are both great for windscreens and fibreglass, but useless in the joint between windows and van walls. the joint on these is constantly flexing
