Drainage issue and Cracks

prats · 7 Aug 2020

We are in the process of purchasing a house. The sale is dragging on for a few reasons but there is one sticking point that is preventing us from committing. We recently did full building survey The house is 1970s build and the surveyor has raised drainage issues as he noticed few cracks inside the bedrooms and one crack outside where the bathroom is . According to surveyor the crack could be due to drainage issue and is fixable. There is no evidence of subsidence.

We will go for drainage survey what else are our options. Please pour in your experiences and suggestions. Thank you so much!!

That's contradictory. A leaking drain causes foundations to move, to subside, which causes walls to crack.

What's below that crack in the first image?

In the first picture, you can see the down pipe from the guttering, start from there.

There is flat roof attached garage , so should we back off or should we proceed? The only think i am worried is are these major structural issues?

Our Building surveyor assured us these are not bad cracks they are quite common and fixable.

Thank you so much. Should we proceed with sale or investigate more? Is this subsidence?

Cracking in the same place on the internal and external face of external walls could be a sign of foundation movement.

Cracking on internal walls is normally something else.

You may be better off getting the opinion of a structural engineer,who would be more qualified to comment than a typical building surveyor.
