The joint at the stone/ trim does not allow for expansion/ contraction where dissimilar materials meet. This joint is to be a backer rod/ sealant style joint. The sill lacks the metal flashing.
The sealant joint at he window/trim is not done to correct specifications for a vinyl window. Most manufacturers of vinyl windows specify a joint width of 1/4″ to 3/8″ minimum to be sealed with a backer rod and sealant-style joint to allow for thermal expansion of the window.
In addition to this detail being incorrect in the first place, the sealant is not applied in a complete manner. This is missing the metal flashing at the top of the sill.
The trim at the window lacks a correct joint at both the window and the masonry veneer. The top trim lacks both the metal protective flashing as well as a drainable weep screed detail.
A 4″ clearance is recommended from grade to the masonry veneer. Also suggested is the use of a weep screed to promote drainage of incidental moisture.
The dirt is backfilled over the face of the masonry veneer, ignoring the 4″ clearance of stone to grade.
