TOPIC: Grading - do you ever recommend an evaluation by a specialist?

Hello all,
I just had an inspection with a grading issue.  This was a 9 year old ranch home with a full unfinished poured basement.  There was one small wall crack in the back wall that had been recently sealed.  The crack went from the bottom corner of the window to the floor.  No evidence of moisture anywhere.    The owner said they bought the house new and the crack was there.  There was a slight grade in the back yard from the house out about 16 - 20 feet for about half the length of the house.  The soil was up to the vinyl siding so it wasn't going to be a simple just add top soil and slope it away job.   
The grade on the side of the house appeared to be flat.  The top soil was right up to the siding there too.  The neighbor's house was about 3 feet higher (12 feet away).  Would you recommend an evaluation by a specialist or just note what you saw?
Would you ever recommend an evaluation by a specialist for a grading issue?
Thank you

No, because it literally is just a "weak mind, strong back" type of correction. If it involved more than just shoveling dirt, like say a retaining wall or drainage system, then I would suggest a landscape contractor but that doesn't even rate as much of a "specialist". You should at least suggest a correction, but I wouldn't feel obligated to say who should do the work.

Hey Cameron,

How would you suggest correcting this issue if the soil is already up to the vinyl siding?

Thank you

It doesn't need "evaluation", it needs to be "fixed"!

As you make it seem that the grade can not raise against the house, than it needs to go down in the middle and sub-surface drainage installed.

Ditto what David suggested. They would have to shave off or dig out to create a shallow ditch known as a swale, which would redirect water around the home. Not every situation has a perfect solution, and the more complicated it would be to direct water away the more likely it is they will need more than just a change in soil level. It may seem over the top to suggest they need to move yards and yards of dirt, but that's the result you get when the final grading done by the landscape contractor is performed with no thought to site drainage.

Thank you for your answers. 

The reason I asked is because I recommended a specialist take a look at the yard grading to give my clients a good idea of what is going to be involved to correct the issue and how much it will cost them.  The listing agent had a cow.  Re-grading/excavating can be expensive.
