Fencing- 21 Jul 2026
Lucian arrived on time. He explained what he would do and what materials and got on with the job. A lot of shrubs to cut and clear and he tidied and swept up as he went along rather than all at the end. Fence was erected neat and secure. Job well done.

Extensions- 29 Apr 2026
Heera, Jagthar and team was my first personal experience with builders. Let me tell you, it was a pleasure to have them do our porch and other renovations in the house. They are so courteous, hard working and provided a great service. Firstly, I had a comprehensively written quote breaking down all of the steps required. Heera then ensured to keep me in the loop of any developments/any changes of plan required, outlining the reasons why and options, making it easy to understand and work together to completion. Their finish was to a high quality and they would always go the extra step to ensure this. I highly recommend AS Builders for any job and will definitely use them again in the future, and would recommend to my friends and family also. If you are considering them, grab a free quote and go from there... That's what I did! Thank you AS Builders for our renovations!

Restoration & Refurbishment- 13 Aug 2019
David and his team were excellent. They are always on time and very professional. They always cleared up at the end of the day thereby leaving very little dust or dirt around the house. No query or issue was ever insurmountable; the answer was always "no problem", which was a joy to hear when having such a large project to do. Each different team i.e. electrician, plumber, arrived exactly on schedule so there were never any delays. The end result was amazing. I highly recommend David and his team.

I've used Facundo's team to install a new shower, including wall and floor tiling, massage jets, and concealed shower equipment. Facundo was the person we dealt with at all times, although someone else was assigned to do the job. The quality of the work and finish is extremely good. I was also impressed with Facundo's professional attitude at all times, being very polite and respectful, as well as proactive in addressing any potential issues affecting our planning and execution. Highly recommended.

Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy

Extensions- 28 Jul 2017
Tony and his team recently completed a large ground floor extension. The guys were polite and courteous, on time every day, worked hard through the day and kept a clean and tidy site. Tony was very good at anticipating issues before they arose, making useful suggestions and giving us time to plan. We had a previous bad experience with a cowboy builder and Tony was especially sympathetic and understanding. Tony and his team were always transparent and upfront and very easy to work with. Tony was recommended by neighbours that he had worked for and we would also highly recommend him.

Emir did a good job. The company did a bathroom refurbishment after water leak, repaired the damaged ceiling downstairs and painted the room. Emir’s attention to detail is very good and he went the extra mile to do the job properly. I will recommend his services.
