Angelina, it's a home renovation show. Mike Holmes is a contractor with great knowledge, skills, family, crew and gets things done. The episode I posted quotes from had a previous shoddy and ill-willed person who caused many problems and did damage to the home. Holmes stripped out the damage that was done. Everything was rebuilt in solid, skilled ways.
This is from a different episode:

dawnrising, I'm starting to be very grateful for the full renovation!! Structurally sound life, with expected good surprises as everything is rebuilt.
