Rusting gutters and excessive rain water flow causes overflowing which will lead to  major issues underneath and likely water damage to ceilings walls and roof space 

Gaps at the top of windows not flush with their brick lintel due to faulty workmanship or building movement.  Results in inadequate seal on windows, compromising heating and cooling and potential leakage during wet weather

Pathways with inadequate fall and drainage. Ponding to low lying areas causing heaving to the  dwellings foundation materials and causes structural instability

Downpipe base PVC connections pulling away. Insufficient drainage connections which can cause settlement & cracking to the dwellings brickwork and their slab floors.

Inadequate down pipe base connection points which will cause flooding and cracking and instability to the concrete pathways around a dwellings perimeter.

Internal flooding to garages where the external ground level is higher than the internal floor level.  Mould growth on internal wall surfaces!

Failing boundary retaining walls causing side pathways to collapse which cause trip hazards.  All retaining walls over 750mm high must be certified by a Structural Engineer.  Inadequate fencing

Make sure all leaking gutters and downpipes are appropriatly sealed.

When concrete patios or slabs are placed around drainage pipes and the slab settles it can pull the pipe connection apart.
