I have done a lot of interior and exterior finish work and know how very challenging some of these jobs can be. There's no doubt in my mind that they are doing the work for the amounts and frames of time stated, and the outcomes are in wonderful, in some cases spectacular.
I think the most impressive remodel was the 3rd episode for season 1, the Clegg Family. First, I have to say that I was kind of floored that the mother in this family was nervous the end result would take longer than a week and not be to her taste, considering the state of the bathroom, the work they took on for the kitchen, and the monster of a wardrobe in the bedroom. It was all such a disaster, anything would have been an improvement, to taste or not. You could actually say that about all three living spaces. Truly daunting projects.
The designer has the ability to look at these messes on top of messes and create a vision, but the really amazing part is the drive she brings to meeting the challenge of both time and cost, even when the scope seems to do nothing but escalate. As someone who has a tendency to get out the charge card, it was an education to watch.
