The retaining wall on Elaine and Bert's property was starting to fail when a contractor working next door offered to help. As the job gets underway, the contractor is never there to supervise and it quickly becomes clear that the work being done isn'... (more)t up to par. Elaine and Bert contact an engineer who confirms what the couple already suspect: it’s all wrong. Instead of making it right, their contractor completely gives up and literally picks up his tools and goes home. Mike Holmes takes on the challenge of finishing the job the contractor started and shows exactly what can go wrong when you don't do the homework that leads to the right pro.
