The worst affected victim, a 70-year-old single man from Great Ayton, North Yorkshire, lost £58,000 and was left penniless by the repeated con.
Another victim, from Billingham, Teesside, lost £40,000 for work on her bungalow, while a couple from Northallerton were conned out of almost £8,000.
Richard Bennett, prosecuting, for North Yorkshire Trading Standards, told the court: 'They would finish the working day at 11 in the morning and they would go to the pub for the duration of the afternoon and drink until the money ran out.'
Mr Phillips, 41, of Redcar, pleaded guilty to conspiracy to defraud today, after he initially denied the charge.
Mr Richards, 51, also of Redcar, said to be the ringleader, and Mr Chaffer, 45, pleaded guilty to the three-year conspiracy at a previous hearing and were not in court today.
The case was adjourned until this afternoon when the court will hear Phillips's basis of plea.
