Chris and team were professional, worked very hard and to a very high quality, also importantly to us they worked to the budget and timetable despite issues with other subcontractors.
Chris and his team did an excellent job of renovating our 5 bedroom house. The finish was great quality and reasonably priced.
The site was kept tidy & well organised during the work and good progress was made each day. All the team were positive to deal with and the end result is excellent.
Everyone at PBC without exception is professional and kind. It was a pleasure working with the whole team.
The project was completed on time, to a high standard and with the minimum of fuss. I would have no hesitation in recommending Chris and PBC.
Their professionalism, transparency and finish are to be highly commended.
Chris and his team did an outstanding job, willing to be creative and practical when solving the magnitude of decisions and problems that had to be navigated. It was delivered on time and to budget.
It was great to have a team you can trust and you can rely on to do a top quality job.
Great work from Chris and the team, always proactive in finding solutions to any issues encountered.
All the work has been carried out exactly as I wanted and with as little inconvenience as possible.
Extremely happy with our new kitchen, everyone went above and beyond our expectations.
