Cement poured against Hardi Siding

I know I’m a little late on this thread, but…
Your answer is it’s nobody’s fault?? That’s a contractor’s answer…
Sure it is. Every single one of them compounded the problem. Each one further along the line is more to blame than the previous until the “builder” is informed. Then it’s 100% his fault. Your builder doesn’t typically build the house, he coordinates the trades. It’s that person’s responsibility at the end of the day. Sticking homebuyers with delayed problems should be a punishable crime. No joke.
I had an identical situation on a covered porch. Cost to do it correctly the first time: exactly $30. Cost for me to repair the problem: $3,865.11
