Woke this morning to find a leak coming in on the inside of the join between kitchen window and plaster wall, as per photos.

How can I repair this please?

It is still raining at the moment but there is the chance according to the weatherman of a dry spell tomorrow morning, would hope to do something then as there is more rain to follow!!

Thanks for any replies.

We had this very problem last week! DH cleaned out all of the old mastic on the outside of the door and resealed after making sure it was completely dry and did the same on the inside beading of the door.

Since this has been done, no more water has been trickling in so it may be that your mastic has got old and cracked.

your image in picture 3 looks like it's the area that's causing the problem , but i would wait until it has all dried out , then remove all that sealant along the top edge and then reseal it , make sure you use a top quality frame sealant ... dow corning or similar , don't get something cheap from homebase etc

don't do this raining , get a good quality sealant , after drying roughly sand up the area first , though a trick might be to get one of those blow drying hair dryers outside on a lead and give it some heat to really dry it out first, then using a gun for sealant you may find that you need to chop off more than you would for a bath to give a thick solid covering , grease in with spot of washing up liquid

Many thanks for all your replies and advice.

As yesterday was dry I took a good look at the brickwork above the window and all looks fine, all morter intact, then took a quick look at the roof and that looked OK as well.

Therefore decided to seal both joints above the window, lintel to brickwork and lintel to wooden frame, does not look very pretty, but we will replace the window in the better weather for a UPVC type instead of the alluminium.

Now will wait and see and hope that has done the trick.
