Hello guys, I've made an offer on a house and recently did a B&P inspection. It uncovered some major issues in the plumbing of the house. The one most worrying is that there is evidence of possible water pipe leaks behind the brickwork (white efflorescence and brick spalling/crumbling). Such white kind of "salt" is visible in many places on the walls of the house (see photos attached). However, there are no visible leaks on the inside of house walls. Has anyone dealt with this? Is this a huge pain to fix? There is also a significant moisture reading behind the shower wall which probably means that the shower tiles were not sealed properly. While not that expensive to reseal if the plumbers are saying that if significant damage was done to the wall itself (which can only be uncovered by opening it up) it may require significant money to fix. Also, there are issues with drainage with down pipes are not connected to storm water. On top of that there is no chemical barrier around the exterior perimeter of a structure to prevent termites (got quote of $2850 to do the treatment). Initially wanted a low maintenance house (and thought that it was the one) but now have significant doubts. My thinking is that it's better to let it go based on unsatisfactory B&P inspection results. Thoughts?
