The roughcasting on the front of my house is crumbling. Does it need replacing?

Yes it needs hacking of and replacing, patching isnt a good idea. You may be able to have it done via your insurance company, they will probably want you to get at least three prices.

Hi I'm guessing this is due to an ingress of water that has frozen and blown the render from the substrate?? Or is it a simple case of tired and old giving way? Dependant on the overall condition it may well be a case of patching in (use a specialist or you'll see the patch from the moon) Or the surrounding area removed and patched in. It would be worth breaking out the ladders and going round it's entirety tapping to hear if the majority of the render is still affixed firmly to the substrate or hollow sounding, meaning removal will be needed at some time in the future. If it's a case of 50% or so of the area is blown, I would consider having the area renovated with a new external finish, this depends on budget of course. If it is time to replace i digress Try to seek out a skilled plasterer or rendering specialist who's work you can view in person and possibly some work from a few years back. Not internal work but the kind you require and the quality you are seeking. Quality external finishes really last the test of time. You may find this person is far from cheap, but quality rarely comes in a small price bracket. Pay once, sit back and forget. Hope this helps Matt

patching up is not a good way it will need stripping and 2 coat rougcast it is not a building insurance job regards kelvin

no not an insurance job and yes it does need replacing

Blown render needs to be cut back as far as needed , if not problems will arise again. Any blown render which has happened due to water intake . Must be accessed And water proof render applied. Hope this helps R, Carrigan
