Help Second hand shed looked dry but now it is up in the garden the walls are all leaking! It is horizontal tongue and groove no sign of rot. Anyone any good ideas of how to leak proof it??

Hi Jackie
Is it the walls letting in the water or the roof absorbing the wet and it running down the walls?
The roof may need new felt - that's a pretty straightforward job http://www.youtube.com/watch?v=1mo5PyRRZm4
If you're sure that the rain is coming through the walls, check that they're the right way up - with tongue and groove, the tongue should be at the top.
Has the wood been treated in any way?

Hi, Jackie......I've had this problem in the past and to be honest most sheds with ship-lap or tongue & grooved boards have a little seepage during very heavy rain. However, you could seal the gaps (during a dry spell) with either clear silicone sealant or weatherproof caulking......both applied with a mastic gun.
Good luck.
Just another thought - was the shed under cover when you bought it? If it had been stored in the dry the wood might have shrunk and loosened the joints. If that's the case a good soaking in a few downpours should swell the joints and cure the problem

Perhaps it would be apt to add this to this thread.
The cheap mineral felt sold & used for shed roofs has a very limited life.....it usually succumbs to high winds or rotting after a very short while.
I have a large/ish shed and summerhouse, both were felted as above when new. When they needed re-felting, I decided to have them both 'hot felted' by professional roofers...it cost £100 per building and came with a 25 year guarantee.
The process involves the roof being stripped clean, an under-felt being applied, this is heated & melted with a flame-gun, next a heavy duty mineral felt is laid on to this and both are fused together, again with the flame-gun.
No nails are used and it's a really neat job.
Hope it resolves itself without too much dampness. If it continues it's possible to put an outer cladding of weatherboard on the walls - you could even introduce some insulation when doing it - just think how cosy that'd be
Good luck!

I'd also find out if the freezer is suitable for being outdoors. You can't just put a standard freezer into an outbuilding of that sort.
