  We used Kolong for our whole-house renovation in the inner west and we are really happy with the outcome. We appreciated the wholistic approach and the various hiccups along the way were addressed to our satisfaction. The whole team were good to work with and kept the site clean and tidy. A special shout out the the project manager Sean who was fantastic - a calm and clear communicator, followed up our questions and proactively looked for solutions to meet our expectations when challenges inevitably arose. Thanks Tony and Sean!

  At short notice, Tony was available to advise on a sagging gutter that turned out to require remedial work to our front awning. From beginning to end, Tony and his team were swift to respond, clear with plans, and expert in their work. At all stages, communication was clear and reassuring. Kolong were happy to answer any questions we had, and delivered a flawless result at a busy time of year (pre-Christmas). Scaffolding was erected and down within a week, with minimal inconvenience. I can confidently recommend Tony and his team at Kolong.

  I cannot recommend Kolong highly enough for any building or renovation project. Tony and the team have been extremely attentive and accommodating in our renovation, which began as a simple kitchen and bathroom re-do but ballooned into extensive remedial works through the whole house. Kolong have been fantastic throughout the project, with thoughtful insights and solutions from their experience. They know and understand the quirks and personalities of older Victorian and federation houses across the Inner West and Sydney. And they have continued to be wonderfully accessible and helpful in follow-up with minor additions etc since the project concluded.

  We completed our renovation and extension with Kolong this year. We chose them among a few other builders. Even though their quote wasn't the cheapest, it's detailed and they are always very responsive. The build process was swift and they're always here to listen to our concerns in an empathetic and professional manner. When problems come up, they are willing to explore ways to solve the issue. We're very appreciative of Tony, Sean and team's work that enabled us to move into our new family home. We have since recommended them to a few other friends.

  Kolong provided a professional waterproofing and deck solution ahead of time. The team was punctual, professional and pro-active in discussing the solution with us for the best possible outcome. They left the site clean at the end of each workday and we would highly recommend Kolong Building Services.

  We can’t thank Tony, Sean, and the team enough for the fantastic job they did renovating our terrace in Stanmore. The quality of the workmanship was excellent, they communicated clearly throughout the whole process, and were upfront and transparent at every stage. The result is exactly what we hoped for, and we wouldn’t hesitate to recommend them.
