“Outstanding craftsmanship, helpful, informative, brilliant work ethic, attention to detail and all round nice guy with a competent and efficient team… competitively and fairly priced… Five-star recommendation!”
Amanda Knight

We cannot thank Jamie and his team enough. During what became a lengthy renovation due to termite damage Jamie was always onsite or a phone call away when there was another curve ball thrown our way. A Master Builder who works with other trades held to the highest standard. We are incredibly happy with the end result, finished to a high standard. The process was helped along because Jamie is just a downright nice guy too. Five-star rating from us!!”

“JAK Building Services were on quote, on time, produced quality work, provided great service. We were really happy with their work”

Ian Naylor

“Jamie is an excellent builder and I would thoroughly recommend him and his team. We worked together over the course of 9 months on a challenging residential renovation with very tight time deadlines. Jamie’s technical skill, ability to develop quick rapport and trust with the client was impressive. No problem was too much trouble for Jamie and he remained approachable and efficient, even when under pressure. I’d be happy to speak further with anyone considering engaging Jamie.” 

Fiona Shakespeare, Shakespeare Design

“Jamie was friendly, hardworking, delivered the final product on time and cleaned up everyday!!! Best builder we have had!!”

Bree Young

“Jamie renovated our terrace in Summer Hill after a tree fell on it and damaged it. He did an amazing job. The finishes were beautiful. Jamie is very trustworthy and his work was outstanding. I would recommend him to anyone looking for an experienced and quality builder… Thanks Jamie it is incredible.”

Susanna Hardy

Michelle McAndrews

“I highly recommend Jamie. His work is exceptionally high quality and is always thinking about the big picture. Jamie’s attitude towards his work has been always what is best for the project, the clients and is mindful of how much the work costs. His value shows in his experience and knowledge, and the exceptional tradesmen he uses.”

Aaron Hunter

“Jamie and his team renovated our house nearly ten years ago and it still looks fresh and contemporary today. His team are reliable, honest, highly skilled and just good fun to interact with each day. Jamie has clever building solutions to complex design problems. He listened carefully to our architect’s ideas and made them a reality. Our project was within budget and ahead of time because he and his team show up early every day to get the job done. We would (and do regularly) recommend JAK to anyone with a build project, large or small.”

Tim Moore

“Jamie has completely renovated our home at different stages and did an awesome job every time. He has replaced all our windows and external doors, built a gorgeous merbau deck, laid lovely blue gum floor boards, blue boarded our upper level and rendered our whole house and redid our bathrooms. Everything was expertly finished and we were so pleased with the result. Jamie is very easy to talk to, completely reliable and cleans up after himself like no other tradesman we’ve ever seen!”

Nicola Don

You’ve probably all heard the stories about the builder or the tradesman who is really hard to work with. The sort of person who overcharges or adds extra things into the job that you didn’t expect. Well, Jamie Kuschert is none of those things. He is professional and always has his clients’ best interests at the heart of his work. His workmanship is excellent and he is a builder that you never need to watch closely because you know you’re always getting an excellent result. A large part of the job that Jamie completed for us was a garage and driveway that is located below a hill with considerable runoff. Even during the cyclonic storm in January, when the hill beside us turned into a river, we had absolutely no flooding issues. We said to each other, “Thank you Jamie!”
