Hire a licensed Security Installer for Intercom Install

Cost is driven by system complexity, whether existing wiring and power can be reused, and any compliance or multi‑unit coordination required. A straightforward like‑for‑like replacement is typically less costly than a first‑time install that needs new cabling or wall chasing. After‑hours attendance and difficult access can also increase the final cost.

• Intercom type and features

  Basic audio units are usually simpler than video systems or setups that include controllers, switches or integration with other building systems.

• Existing wiring and power availability

  If existing mounts and wiring can be reused the job is typically quicker, whereas first‑time installs that need new power or low‑voltage runs increase labour and materials.

• Extent of cabling and structural work

  Wall chasing, long cable runs or significant riser work add time and materials compared with surface‑mount or short‑run installations.

• Multi-unit and compliance requirements

  Strata, commercial or compliance‑driven projects usually include extra coordination, commissioning and paperwork that increase scope and time on site.

• Access, timing and after-hours attendance

  Restricted access, site complexity or work outside standard hours typically attracts higher rates and can extend the schedule.
