Ness Alarm and Security System Maintenance

We regularly maintain thousands of alarm systems throughout Sydney and the surrounding suburbs on a monthly basis – book an appointment before 8:59am and we’ll see to your project on the very same day!

Regularly servicing your alarm systems ensures the utmost protection for you, your family and your business – as with most things in life, an industry-leading security system requires due care and attention, missing out on essential maintenance can end up costing you more than just a new alarm system.

Arrange to have a one-off maintenance service or organise to have your property serviced by a specialist on a regular basis.

Most insurance companies and leading security firms recommend that you have your domestic alarms and security products serviced at least once a year and at least twice a year for commercial or industrial properties. If your alarms were to fail as a result of not performing essential maintenance, you may lose the right to an insurance claim, depending on your policy’s terms and conditions.

Book your maintenance service today to avoid any confusion and save yourself a world of worry – just call us on 1300 003 746 and see what we can do for you.
