Honestly, the roof wasn't expensive. - Knowledgeable - Scaffolding - PPE with an FFP2 mask is not enough - Packaging - Tools You somehow add all that up and it costs. The handling, the disposal, etc. The panels can't be put into the BigBag via a chute, the BigBag can't go on a trailer. Are they even allowed to be transported like that? I don't think so. Our BigBags were standing there for days. If you want to comply with everything, you won't come much cheaper. You can gut the building yourself, you just need a lot more time than a company. Besides, I would have removed much more and sorted more precisely. Every move is precise. Our demolition company has their own crews for gutting. It just looked effortless.
