Patio stain damage (cypress)

[Peasgood]

If it is rust stains you can get stuff from Halfords to remove them. Probably worth a try anyway at this stage.

Use it when we get stains from moss treating lawns with iron. Give it a squirt, brush vigorously with stiff brush wash off with lots of water. Seems to make it even worse initially but does work, try it out of sight first if you are worried.

I don't get how the trees can have stained the patio in the first place, have you formally acknowledged that you have caused the damage yet? This sounds a bit like the famous sawdust causing car to need a respray, in which case you say you'll need to refer to your insurers and they will most likely tell him to go away, politely.

lots of these chemicals make the rust stain 'bleed', don't use it on natural stone. You'll end up with blood red stains far bigger than what's there now.

Some of my indian flags have that staining on from out of the pack new, i just put it down to a small content of already existing ore being in them from when they were formed. After all they are a sedimentary rock to start with

I went to see the job and offered to try to clean it later in the week. I have been working professionally in this business full time since 1978 and this is the first time I have come across this. It’s not actually the customer...she’s happy with the work. It’s the neighbour (who requested the work). He alleges that when he came back from a weekend away, that the patio was stained after we had been on site. The patio was laid 2 weeks ago.

My advice would be do not get involved/engage or you will open a can of worms. This is all hearsay and utter nonsense. If you have directly broken something then yes of course act in the correct and professional manner if you have some chancer trying it on, ignore!

What is he alleging has made the staining? Sap, chain oil? It looks more like rust marking.  Do you think it was actually you that caused it? Ive seen the metal straps used to strap flags cause  rust marks. But normally in a banding pattern. What is the pattern of the staining? Is it more prominent nearer where you were working? As for a remedy, if it's natural stone, it won't be easy, as whatever it is will have absorbed,  and most detergents will stain/alter the stones natural colour

The guys a chancer, you sound very honest!

  
best thing to do is pass your insurance details over and let him try his manipulation tactics on someone who deals with them every day!

  Not a nice guy like you! 

  Then block all his numbers and don’t beat yourself up about it.

Perhaps the problem is that the stones were not sealed yet so extra porous and therefore potentially  harder to remove stains etc .

as already said though seems more likely they are just a chancer or just assuming that the  oil marks must have came from the tree or a chainsaw .some diy shops sell similar  types of stones individually so could do a quick test trying to stain them .i bet it Would come off
