What people don't expectPeople expect a lot of mess with insulation. Sheeted properly and cleaned down at the end of every day, it's far less upheaval than they think.

In Lee's words
Walking back through a house once it's finished. You can't see insulation when the walls are boarded, but the people living there feel the difference straight away.
Clear the rooms we're working in before we arrive, and ask us anything. After this long in the trade I've heard every question, and there's no such thing as a daft one.
