Have you watched it? Years ago, I saw several episodes. Probably more than several. Don't judge. It was on, and I had to sit there for hours.
Anyway, the thing that always struck me was all the 1-off things they did. This team of...people...came to the house of people who could not afford to care for their house. The owners were usually sitting around, watching TV in a house that was falling apart. This team then did a quick hack and slash of the house, and rebuilt it with a bunch of 1-off items. Basically, maybe 30% of the work was completely custom. The exterior of the house was dramatically improved. It didn't seem that the homeowners were involved in the work, or that the homeowners were given instruction on maintenance. So, a rush job, with a bunch of untested work, and then the owners are left to deal with whatever happened afterward. Many of the materials were closeout, or the last of whatever. The team was always so happy to have gotten the last one.
Yes, some of the houses started having problems instantly. Either way, property taxes went up. How do the owners afford this? Repairs come up. The only solution is to remove down to non-custom stuff, and start over. Who pays for that?
I'm no professional, but some of the work seemed to have been done incorrectly. Apparently, some of the electrical wiring was done incorrectly.
My question is, were the owners of those homes actually better off from the makeover?
