Finding people to do maintenance on rendered external insulation

Our house retrofitted in 2016 as part of the Green Deal programme and the render needs to be maintained as it is starting to crack. We have been trying to find someone to do the work, but to no avail as I believe that it is a fairly specialised job. Any suggestions would be greatly appreciated as we have tried to contact the original contractors, but to no avail.

Cheers,

Julian

I know of a couple of plasterers doing internal plastering with lime plaster - not sure if they have experience with external but you could ask.

Thanks Eric, at this stage I think we might just need a few minor patches and a repaint.

Hmm, is it not something you could try and learn how to do yourself?
