Hear what other’s have to say…

“P J Cook has an exceptionally professional manner. With his technical knowledge, expertise and work ethic – you won’t find a better builder.

You are destined for greatness in the building trade and roused me to the challenge of how I can make my own customers experience better. Excellence all the way through.

Our front deck was completed with no fuss. We have had so many positive comments about the deck and it is obvious to everyone that looks at it that the workmanship is flawless.

“I never thought adding a granny flat to our block would be this easy. I’d recommend P J Cook to anyone keen to add value to their property.”
“We love our new granny flat. In fact, we love it so much we’re moving into it ourselves and renting out our home!”
“Peter always arrived when expected and arranged other tradesmen to complete specialised sections of the work. His attention to fine detail was first class. I am extremely satisfied with the final result!”
“We didn’t have to do much homework at all – P J Cook provided all the information. Even the Council approval process was simple and easy – Peter looked after the lot.”
“It all went to the required timelines. Peter gave us an estimated date of handover and stuck to it. Our build didn’t run over at all.”
