    We had an extra data outlet installed in the house and the job was done neatly and without any fuss. The technician was friendly, tested the connection afterwards and left everything clean. Happy with the result 😊

    Really happy with the cabling works at my property. We had strata requirements for no visible cabling, and he did manage to run everything through the wall and roof cavities. Technician was very knowledgeable, professional, easy to deal with and did a great job. He went above and beyond to ensure everything was done properly. They back up their work and when requested, he also came back same day. Very happy with the result and would definitely recommend Data Cabling Guy.
