Within an hour of taking my call Nathan was on-site and resolved my plumbing issue. Prompt, attentive and friendly service. Also provided advice and options on a separate issue for a future plan. I have used JSW many times previously and will continue to do so.

Had a couple of water leak issues. They were able to come within a few days and actually arrived earlier than expected on the day! Nathan fixed everything within an hour with friendly and professional service. Would recommend to anyone!

It was two days before the Easter 2026 break, I had to replace my fourteen year old hot water system, and rang up Belinda from JSW as I was desperate to have the system working prior to the Easter holidays. Belinda from JSW immediately arranged a booking for me and got someone to come up on site the next day and do the job. I am extremely satisfied with how Nathan handled the entire process from start to finish. The entire thing took approximately two hours and all systems up and running. Truly Nathan did an excellent job and was very professional. I will recommend JSW for any future plumbing and hot water systems requirement. JSW and team thank you very much for an excellent job!
