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.
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.
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.
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.
Their professionalism, transparency and finish are to be highly commended.
