See why our customers love us

Cris and team were professional and immaculate in solving my nbn issue, from working with the building manager, being respectful to noise level to my apartment neighbours and carrying out the work efficiently! Would definitely recommend them for any electrical/ data cabling work!

Thanking Jordan and James from CMK Electrical & Data for the install. No fuss, arrived on as promised time while displaying a professional, friendly and courteous attitude whilst performing the work. Definitely will seek to have this company perform my future electrical or data cabling work

These guys were quick and efficient and did exactly what I asked them to do. They cleaned up after themselves and were very courteous. They were on time and the office kept me informed of arrival times etc. I would use them again any time.
