The pugnacious pair investigate an OAP builder.
Dom and Melinda go to Bradford to help a couple who hoped to build an extension which would provide a bedroom to each of their children. Ayaz and Shazia spent £30,000 with a father and son building team to do the job. Instead they were left with a whole host of problems – including an extension without a roof, exposed live electrics and a number of inadequate steel beams. The parents and two daughters are forced to camp in their lounge, while their two sons are stuck sharing a freezing, damp-ridden bedroom.
It's Dominic's mission to find out how a supposedly experienced builder – with three decades of building under his belt – could have made so many basic errors. It's not long before he uncovers a string of unhappy customers, a suspicious lack of paperwork, and a wayward son whose work - and behaviour - on site is a major cause for concern.
Meanwhile, Melinda's got her hands full with the massive building project. Hampered by the problems she uncovers, Melinda appeals to the local community to help the family. She's inundated with offers – including one from the local rugby league team.
When Dom finally catches up with the builder, he finds a man in denial about both his building work and the actions of his son.
