Here's what the contractor says:Parging crack, DIY after first year, this is normal house maintenance, $1700, well, have you ask why ?
Wall crack within 7 years, asking for your builder to have a look first. If you lucky, and get water leakage within 2 years, your builder has to fixed it.
Crack wall and Crack Parging are different. But Parging crack could be an early signal for wall crack. But please understand the issue before pay the contractor !
