Our Services

Milliken Builders is an Illawarra custom builder with over 30 years’ experience in the carpentry and trade industry and over 20 years’ experience building. We specialise in big and small extensions and renovations but can also provide building solutions for small projects and new homes.

We pride ourselves not only on our quality workmanship but also our friendly, reliable and professional approach.

Whether you’re planning an extension/renovation or a whole new build, talk to Milliken Builders. Our experienced team can manage your building project – large or small – from beginning to end, ensuring that the finished product is exactly what you want.

You may wish us to take the project completely out of your hands and see it through, or you may prefer to organise part of the building work yourself. Either way Milliken Builders can assist and you will love that you get to talk to the same person throughout the whole project.

Why Choose Milliken Builders Illawarra NSW
“Did a quality job on our renovation”

Did a quality job on our renovation. Communication was good especially with covid restrictions not allowing us to be at the property while renovation was occurring. Gave me some good ideas to use in the bathroom. Quality work from both the Millikens and their contractors. Would definitely recommend Milliken Builders.

"Milliken Builders did a great job"

Milliken Builders did a great job. It was done with quality, strength, reliability and neatness and all of the tradesmen were courteous and polite to work with. I would highly recommend this Company for any building or renovation work to anyone wishing to employ them.

John – Robertson

"Friendly & professional"

Troy and his team recently did a cedar window replacement and another small structural job for me. They are friendly and professional and as the jobs weren’t straightforward Troy gave advice and options to resolve some small unforeseen issues. They worked safely, kept me informed, were punctual and importantly cleaned up any rubbish daily. Recommend.

"Your professional attitude was outstanding"

I thank you so much, it was really great dealing with you and your company. You were always there to help in any way you could, your professional attitude was outstanding.

Kate – Shellharbour

"Your team were very efficient"

Your team were very efficient! My neighbours also commented on this, and asked where I’d found them, so they represented your business well. The neighbours were also pleased that someone moved their bins to where the truck could still access them. Sometimes it’s the little things that can make an impression!

"Overwhelmed by the teamwork of the employees"

I contacted Milliken Builders to install aluminium windows and they did such a great job I then got them to do a complete bathroom renovation. I was overwhelmed by the teamwork of the employees – they were polite, cleaned up after themselves, were on time and I was kept up to date with the progress.

Marie – Gwynneville

"Flexibility and willingness"

The design grew as work progressed so I was happy with their flexibility and willingness to work in with me throughout the job.
