    Hi

    I’m wondering if I could get some advice on the best course of action for some external rendering that appears to be deteriorating.

    It covers the entire rear of a 3 bedroom terraced house and as can be seen from the photos below, has started to crack in a number of places.

    However the majority of the rendering seems to be ok and I’m wondering if it’s a shame to remove all of it when it’s only deteriorating in certain areas.

    Can this be repaired? Or am I best just removing it all completely and replacing?

    What about removing and repointing? Would this be a good idea or should it be avoided?

    Many thanks

    Cracked rendering is difficult to repair.

    Ideally you'd break it all off and start again.

    For small cracks you could dig out and fill.

    But some of your cracks look like the render has blown from the wall and needs to be removed from the wall and then re rendered

    for me i'd take itall off including replacing
    all bellcasts and the rusting corner bead with plastic beads and bellcasts.
    If possibledoing the samework at the same time with the left hand neighbour would be best for you boht.

    Close examination of the side wall might show you more cracks and blown render.

    Thanks guys, I haven’t a clue about any of this so wasn’t sure if it could be repaired.

    Knock it all off and start again it is then

    What’s the typical life span of rendering? how long can I expect a properly rendered Job to last for before it needs doing again?

    totally depends who you get to do it.
    You’ll need to employ someone who knows what they’re doing . You should get 50 years+ from traditional render mixed and applied correctly.
    Your existing render looks fairly recent actually.

    yes that’s why I was unsure over whether it could be repaired because it doesn’t look too old albeit has definitely blown in certain spots
