Walking around back I saw a custom-fit patio.
There's nothing wrong with that, if it is professional and takes common sense into account.
In this case there is not a lot that takes common sense into account.
For example, a small pocket was created in the patio to house the AC compressor.
OK, it's custom fit.
Is there a problem with that? In my opinion yes.
1. The compressor is 16 years old. How much longer will it last?
2. When it is replaced, will the new unit have exactly the same footprint as this one? Will it fit so precisely into this pocket? Not likely.
So then what? We have a built-in issue.
The other thing bothering me is not so obvious in this photo. But it is there.
The entirety of the siding along this wall, and the adjacent wall 90 degrees to this one, is buried by concrete.
And the patio is angled to divert water toward the basement door.
If the siding needs replacement how do you do it?
And, probably worse, this creates two protected, dark, perpetually-wet walls that will be very moist and attractive to rot and termites!
And look, there is a present water source!
There is a large gap where the AC lines enter the house. But even without this hole there is a continual moisture source for rot and the termites.
To me this is a big deal!
I'm not a termite professional, but this patio is 9" deep and that seems like difficult material to control insofar as termite activity.
My recommendation: taking a class on how to do something may not give you all the information necessary to do a job in a professional manner. And if a "professional company" did this work, they did no favors for the homeowner(s) of this house! I do not regard this as a professional job. There are too many built-in problems! So, what to do now? Is it possible to prevent moisture intrusion into these walls, and therefore structural rot or mold? And, very importantly, find out from a termite company if this built-in moisture problem can be controlled and termite infestation prevented. As good looking as the patio may be, it could be the Trojan Horse of Perpetual Problems.
