Dom and Mel are in Bradford, where a hard-working Dad has been toiling day and night to fix the mess left behind by a cowboy builder. In 2002 Naheem and Faye Khan bought a three-bedroom bungalow. Back then they had just one child, Ava, now thirteen - but since then the Khans have added five little boys to their brood. The family decided on an extension, but the stress of all living under one roof caused Faye and the kids to move out – making getting the work done all the more important. But having paid their builder £44,000, he walked off – leaving the Khan family with a half built wreck: without windows, doors, heating or electricity. Melinda has a huge task on her hands to prepare for a family of eight to move back home – with thirteen rooms in need of TLC, not to mention there being no kitchen and no bathroom. Meanwhile, Dom is on the trail of the builder who appears to have left a trail of devastation across Bradford. A pattern emerges of the cowboy giving low quotes, and then demanding more money before the job is finished. When he finally comes face to face with Dom, he makes a startling admission...
