Fixing leak coming down pipe in small lean to Tips, tricks and information on how to spot rogue and cowboy builders and also a platform for you to post and warn others of cowboy builders you may have encountered and help to spread the word of their dodgy dealings

Hi all,

We had a small lean to constructed. Generally all is ok, I fixed most problems my self but I am stuck here.

Water continues to leak through, and comes down on the pipe...

What can I do about this? Internally / Externally...?

Happy to buy and hopefully easy enough to DIY...

THanks

Hi makingalife
Presumably a U cutout was made in the plastic roofing to fit around the pipe. Also presumably a length of flashing has been fitted along the roof/wall join with a cut out around the pipe.
Suggest you fill in above the roof and all round the stack with silicone mastic.
