Jason fixed our oven, and the service was prompt and did as expected. Unfortunately now a few months later I'm getting cold calls to take up free member benefits and have tradies come to our house to look for faults that I haven't found yet. To be honest I found the attitude of the caller rude and disconcerting, questioning why I didnt want to take up the service.. based on the cold call alone I doubt I'll use Fallon again.

We have just completed a full day’s work with the Fallon Team of Kyle M, Dave Y, Kyle Callum H, and Max K. My wife and I cannot speak too highly of the service that the team supplied and the way that they went about their business. Nothing was too much trouble, we were able to make a couple of minor adjustments to the work plan, simply and easily. Thank you for a job very well done.

Very happy with technician, Luke. He was prompt, professional and a pleasure to deal with. I was particularly impressed with his tutoring of his apprentice. I would not hesitate to engage with him again.

Jessy came to install our cold water unit under the sink. He did a great job despite not having seen one of these units previously. We can now enjoy cold water "on tap".
