    Default Water getting into new window

    I bought this 8 x 6 Tiger potting shed in Feb of this year and sealed all the windows with clear waterproof, mold resistant silicone sealant. For the life of me I cannot see how water is getting into the shed (the darker dry water stain is a result of my own from painting with acrylics) as the flow runs off down past anywhere rain can get in. I know we had a downpour last night but when I stood in the shed yesterday while it really poured hard there was no water. It seems that somehow, water always gets in. There is also black mold around the bottom of the windows too. There is no condensation inside the shed on the pvc windows either which rules that out. Pretty gutted as I don't want this thing to go downhill with damp. I could strip it again and re-seal but there are no dry days ahead.

    Any people with better experience of these type of shed windows and stopping water ?

    Is it blowing in under the window frame?
    Have you sealed that?

    The window frame overhangs considerably and it would mean water would have to defy gravity and run backwards and upwards to get in. There are no winds at all and the shed is close to the house which shelters it from wind.

    I'd go out on a dry day with a hose pipe or watering can and try dribbling water in different places to see if I could duplicate the leak and so isolate exactly where the water is getting in - sometimes water will get sucked in to a narrow crack due to capillary action.

    Perhaps exceptionally forceful rain just gets in and normal weather will be ok. I have done this a couple of times already, thinking I have sealed it and no water for weeks and then it gets in. I did yesterday squirt jets of vinegar water at the bottom of the windows from inside to try and eradicate mold but I wouldn't have thought that would pull rain in from outside or would it ?

    It only needs one drop of water to get in and all the other drops follow.

    From the photos my guess would be under the frame somewhere.

    water can very easily go up/down/sideways - whichever way you don't want it to...

    I'd have a close look for cracks/gaps etc all round and then do the watering trick
