Hi guys,
A bit of background, recently built a house in a newer area and moved in and now they are building a house 2 lots down from mine with a lot in between.
I discovered on the weekend a yellow stain on the pavers near the fence line of my house, i figured it was caused by yellow sand (happens with all the yellow sand around, it gets everywhere then when it rains it can stain) so i got out the pressure cleaner to get rid of it but it wouldn't budge.
On closer inspection the yellow was also stained on the plastic downpipe nearby, and seemed to be caused by something else.
I went out to look at the other side of my fence, it meets the wall of my house at the boundary on the empty lot between my house and the house being built - and i've found someone from the building site next door has tipped a bucket of something that has stained the wall of my house yellow, and it's splashed by under my fence to stain the pavers.
The empty lot is littered with there waste, and concrete and other stuff is dumped everywhere - as well as concrete and other splatter over the other side of the fence.
I took some pictures of the issue, it seemed pretty obvious what had happened, and since the builder is the same one we recently built with I got in contact with them to let them know - expected they'd be apologetic and send someone out to clean it.
Unfortunately they've decided to go the other path and tell me they cannot see how the stain could have possibly been caused by them.
What are my options now? has anyone had any experience is anything similar?
Edit: as requested here is a picture - https://imgur.com/f1RwAmx the stain in question can be seen near the shovel, and you can see the whole lot is used as a dumping ground.
MS Paint diagram of the lots plz.
