How much mess does exterior rendering usually make?

[SomethingElseCausingAKerfuffle]

Does anyone have experience of exterior rendering? The neighbours are gearing up to have their house rendered, and I was wondering how much of a mess it's likely to make. They've got a lorry load of "PBS Superbrut" on their driveway ready to go and the scaffolding is up. There's about 2m between his house and ours, and a patio with plants and garden furniture about 1m away.

Is this PBS stuff likely to make a huge mess on our side?

Are there any precautions we should take (other than the obvious moving of patio furniture), or that we should ask the builders to take?

There's been an ongoing neverending renovation and whilst the neighbour is a good chap, I've been less than impressed with his builders, so would rather chat to neighbour before work starts to head off any potential problems...

Our new render went on with absolutely no mess whatsoever. The guys that did it were absolute legends even working in the dark in a Scottish winter with big lights to get the job done.

i thinks ours was K rend.

It's knocking off old render that makes the mess. To be safe I would move the garden furniture and the plants if they are in pots that are moveable. They should (but probably won't) establish a marked and signed dropzone around the base of the scaffolding, usually a radius of 25% of the scaffold height.

Thanks, this is really helpful. We've already had the "fun" of the old render being taken off, I'm still finding dust and debris weeks later 🙄 The 25% of the scaffold height worries me as that encroaches onto our side of the fence... It sounds like we need to ask the neighbour to ensure our side is covered with a tarp or dust sheet or something, I don't want it splattering our paving.

Most of the patio furniture has been pushed away from the fence already (after a brick fell from roof height and narrowly missed our table!) but we'll definitely move the rest out of the way.

The actual application can make a lot of mess on their ground/windows if the builders are not careful but shouldn't;t affect your house. As pp said, its the knocking off of the old stuff that makes the mess.

I would make it clear to the neighbours that any damage will need to be paid for and you have been "taking advice" because of the mess that was left after the rendering was removed. The legal term is "consequential loss".

But then I hate neighbours just because they exist.

Thanks for the further responses. I'll keep an eye open - hopefully they'll start on a non-adjoining part of the house so I can see the extent of any splatter. I'm honestly so over this building work, it's been going on for ages. The neighbour is a decent chap who has been messed around by the various builders he's had in. I'm trying to be accommodating as I know he's not had an easy time of it, but it's exhausting trying to anticipate what the next buch of cowboys are going to do. It's all very well getting compensation if there's a mess or something gets damaged, I'd rather they took more care in the first place! Anyhoo, rant over. I've repositioned my desk so that I can keep an eye on what they're up to 👀
