I did a couple of inspections for people who's property had been "finished" while they were still in the UK. Quite frankly the quality was absolutely abysmal.
Basically, everything that could be wrong WAS wrong. In one property I looked at there were workers living in the property and they'd lit a fire and had a BBQ on the newly tiled lounge floor. There was water running down a bedroom wall where they'd dug into the hillside but hadn't tanked the walls prior to bricking and plastering. Water was also running out of a live light fitting. Patio doors were either smashed or cracked. It was heartbreaking to see what people had paid good money for.
