PhilR Posted September 25 Share Posted September 25 Morning all, I'm after you advice please on the poor/well aged finishing on the front exterior wall to flat roof flashing in the attached photos. I'm about to repaint the front of the house and found this after a thunderstorm and a small leak. My question is do I remove all the old sealant and just refill with mortar down to the flashing or do I need to consider anything else? I am certainly no builder but do have a basic DIY understanding. Thanks any help appreciated. 1 Link to comment Share on other sites More sharing options...
Russell griffiths Posted September 25 Share Posted September 25 Do not re fill with mortar it will crack and become loose. pull out all the old sealant and clean the gap out, re-seal with lead sealant. in a perfect world the render should have a bell cast drip above that sealant, but you probably don’t want to be hacking that off.

PhilR Posted September 25 Author Share Posted September 25 Thanks Russell. Any particular brand stand out as much better than others or are they all pretty much the same? Up close there does seem to be a small lip still there to shed water over the lead. So I'll be careful clearing it out and try and keep it if it is still ok. Thanks again Link to comment Share on other sites More sharing options...
