We're having our render redone and the builders came on Tuesday and hacked all the old render off. They worked solidly for 6 hours, did a very good job and tidied up really well. I asked when they were coming back and they said to check with their boss. The boss is on holiday and hasn't responded to my text about when they're returning. The exposed brickwork is old (1930s semi-detached) and it's raining a lot. We're getting this redone due to damp issues and I'm worried about the impact of this being left exposed for nearly a week. I know literally nothing about building work of any sort so I'm likely being dramatic but the way the bricks look I feel like my house is about to crumble! Will this be okay? I thought they'd do the whole job at once. I had no idea the blokes were even coming that day to take it off, they just turned up and when I rang the boss he apologised for forgetting to let me know the night before.
