Be thankful you're not doing my "project".
It's a f**king nightmare.
Took 2 years to get the same neighbour to disconnect an old lead pipe buried under concrete.. they joined a copper pipe to it & that too was buried under concreted... f**ker leaked and leaked water into our foundations..
Only after the threat of litigation did they disconnect..it was that bad when we had our rear extension done we used a pure dry mix for footings, poured it in to 1ft of water, floor collapsed so we had to shutter it, and practically built the rear of the house in the wet..
They have been a nightmare neighbour who never take responsibility for the utter state of their home..it’s almost derelict.. 😂
Edit.. sitting st Heathrow right now waiting to collect my sister.. 😡
