What our customers say
Testimonials
Your team did a great job with the new cylinder and a nice clean and tidy install. The tenants also commented how nice and friendly the people who came on site were. So thanks for a job well done.
I want to feedback to you how impressed we were with Jason and the work he did for us on the 6th of May. His communication was great. He clearly explained what he was doing and the number of potential outcomes with potential costs. He was really quick to respond and was really friendly.
Derek and DT Plumbing have been our sole go to plumbers for years and will continue to be so. Throughout Derek kept us informed on progress and checked on the job when it was completed. Bloody marvellous response again.
