Intercom installation and replacement in Brussels

An intercom that crackles, a handset that no longer rings, a door release that's stopped working? We install or replace your intercom (street panel, handsets, electric strike), in houses and blocks of flats.

On the installation

Signs it's time to replace your intercom

  1. 01

    Crackling or cutting out

    Voices you can't hear, interference, calls that cut out: the components or the wiring are wearing out.

  2. 02

    It no longer rings

    A silent handset, or a ring that only works every other time.

  3. 03

    The door release doesn't respond

    A faulty electric strike or control: your visitors are left standing at the door.

  4. 04

    Damaged street panel

    Worn buttons, unreadable labels, a panel that's been vandalised or weathered.

  5. 05

    Parts you can't find

    On older installations, replacement handsets are no longer available: replacing the whole system becomes simpler.

  6. 06

    You'd like to see who's ringing

    Depending on the system in place, switching to a video intercom can reuse part of the existing wiring.

House or building: two setups

  • Single-family house

    A street panel with one call button, a handset (or one per floor) and control of the front door's electric strike.

    • One-button street panel
    • One or more indoor handsets
    • Door opened from the handset
  • Block of flats

    Co-owned buildings

    A panel with one button per flat, a handset in each flat and a shared power supply. We coordinate the work with the property manager.

    • Multi-flat panel
    • A handset in each flat
    • Work coordinated with the property manager

    Intervention très rapide un vendredi soir et un jour férié pour une fuite urgente sur notre chaudière. Le technicien a identifié le problème et est revenu le lendemain pour remplacer la pièce et tout remettre en service. Service efficace et réactif dans une situation d'urgence.

Frequently asked questions

Frequently asked questions about intercoms

Can't find your question? Ask it on WhatsApp, with a photo if that helps, or leave your number and we'll call you back.

Often, yes: many recent systems work on two existing wires. We check the condition and type of wiring during the visit before advising you.
