''We just wanted to say a huge thank you for all the effort that you and your team put in to building our homes at Green point. I couldn’t speak highly enough of Coastline Building and team.
Prior to meeting with John, we had shopped around and visited many different builders always leaving feeling confused and frustrated. Constanly being fed “hook” prices to get us in the door and finding out that to fully complete the home was considerably more expensive then once told. However, after speaking with John, we felt at ease. We knew what we could expect without any hidden costs. John quoting was very detailed nothing was left out, which gave us the reassurance that the quoted price was exactly what was expected to pay with no hidden costs. Thank you so much John and team one very happy client. Coastline building is definitely Number one builder central coast ''

''John and his coastline building team rectified a previous builder's mistake in our house on central coast. John and his team were very professional, punctual and they did a great job. We are very happy with the result, happy too, with the cost, which we felt was fair and very reasonable. We would recommend John and his team to anyone''
''John and the boys from coastline building did a fantastic job on our extension/renovation at our place. The attention to detail was 2nd to none and the boys were very professional and punctual.
John made the white process smooth and stress free Highly recommend these guys

"We couldn’t be happier with our new home. The Coastline Building team took the time to understand exactly what we wanted, and the results speak for themselves. Their professionalism and attention to detail were outstanding throughout the entire process."
— Emma & David, Central Coast
''John and his team completed a challenging restoration job on my house at almost 1/3 of another competitors quote, with a very quick turnaround time and a first class result. John was an absolute pleasure to deal with from the minute he received my first call, to conducting the thorough quote and then completing the job whilst I was away on business travel. I highly recommend coastline building and his team and will no doubt use him again in the future when I need further work done - Especially on the Central Coast of NSW where finding decent, RELIABLE trades-people is almost impossible! ''
Thanks again John, Cheers Aaron.
