Had some work done on the house, scaffold went up a couple of days before, work took a week and is now complete. Work was 8k,They added and extra 400 for unforeseen work. Now they want the remaining 5k but have said the scaffolding will be up for around 2-3 weeks due to the owner being busy. Somehow this doesn’t sit right with me. I know there’s probably a cost saving having it on a house and they are trying to secure some more work on our road and so I’m thinking they just want to keep it up for convenience and cost saving to them. I said I’d hold payment until it’s down and they are arguing saying it’s not right. I’m concerned the longer it’s up it could damage the building and so want this as leverage but not sure if I’m being unreasonable. Is there a compromise here?
