An intercom buzzing with no picture, or showing a picture with no sound, is in some ways worse than none.

You still get up. You still walk to the window, in the dark, to see who is standing at the gate. Then you go back upstairs, still not knowing who it was.

What is an intercom repair?

An intercom repair finds and fixes faults on an audio or video intercom, such as no sound, no picture, a gate not opening from the handset, or a dead unit. Common causes are damaged cables, power faults, lightning, worn buttons and failed handsets. If the unit is too old to repair, the technician quotes for a replacement.

We find and fix faults on audio and video intercoms at gates and doors, for homes, complexes and businesses. Most faults are small and give a warning first. If a repair isn't worth it, we tell you, and quote for a new unit.

Faults we see often

Most intercom faults start small. A crackle on the line, a flickering picture, a button sticking in the cold. Left alone, they turn into an intercom nobody trusts.

  • No sound, or sound in one direction
  • A blank or blurry screen
  • The gate won't open from the handset
  • Weather damage to the gate station

What causes them

Weather is the first suspect. Rain gets into a gate station and the sun cooks the screen. A lightning storm can take out the electronics in one night.

Wiring is the second. A cable under the driveway gets damaged by roots, digging or a garden service with a spade.

Power is the third. Load-shedding and surges wear out power supplies, and a dead supply looks like a dead intercom.

We test all three, in that order, because the cheapest fix is the one we look for first.

Repair or replace

Some intercoms are worth fixing. Others are so old the parts are hard to find, or the repair costs more than a new unit.

We test the system first, then tell you which one it is. If a new intercom makes more sense, we quote for an audio, video or GSM unit to suit your gate.

A GSM intercom calls your phone, so you can answer the gate from anywhere.

Intercoms for complexes

When a complex intercom fails, it fails for everyone. Visitors can't reach anyone, deliveries pile up at the gate, and residents start leaving it open.

We repair multi-unit intercoms for complexes, estates and office parks, including the panel at the gate and the handsets in each unit.

Send us the make and the fault, and photos of the gate panel if you can.

A gate left open "until the intercom is fixed" stays open for weeks. Every resident knows it, and so does everyone else. Fixing the panel closes the gate again.

We offer service level agreements and finance for your intercom repairs. Each one is a service contract with 24-hour support at night and on weekends.

Frequently asked questions

Can you upgrade my old intercom instead?

Yes. If a repair isn't worth it, because the intercom is old, badly damaged or its parts are no longer made, we quote for a new one instead. You can choose an audio intercom, a video intercom or a GSM intercom. A GSM intercom calls your phone, so you can answer the gate from anywhere, and it needs no cable from the gate to the house. A video intercom lets you see the visitor before you open. Some newer systems combine both, ringing a screen inside and your phone. Where possible, we reuse the existing cable to save digging. We recommend what suits your gate, your house and how you'd like to answer on the site visit. The written quotation sets out the repair and upgrade options side by side.

Can my intercom ring my phone?

Yes, with a GSM or smartphone intercom. When a visitor presses the button at the gate, the call comes through to your phone, wherever you are. You can talk to them and open the gate from there. A GSM intercom uses a SIM card and calls your phone like a normal call. A smartphone intercom uses an app and your Wi-Fi or data, and a video model shows you the visitor's face. It suits people who are out during the day and want deliveries, family or contractors let in without rushing home. If your current intercom can't do this, we can upgrade it, often using the same gate panel position. We check the signal at your gate first. Our intercom systems page has more.

Why does my intercom have sound but no picture?

When an intercom has sound but no picture, the fault is usually in the camera at the gate, the screen inside, the cable between them or the power supply. A failing power supply often shows up as a flickering or dark picture before it fails completely. Weather damage to the gate station is common too. Rain, sun and heat break down seals over time, letting moisture reach the camera. Lightning and power surges can damage the camera or screen without affecting the sound. Cables damaged by digging, rodents or age can carry sound but not a clean picture. We test each part to find which one failed, then tell you whether to repair or replace it. A photo of the gate station and the screen helps.

Why will my gate not open from the intercom?

If your gate won't open from the intercom, the intercom may have lost its link to the gate motor, or the relay inside it, which sends the open signal, may have failed. A damaged cable between the intercom and the motor causes the same problem. A flat gate motor battery or a motor fault can cause it too, so test whether the gate opens with a remote. If the remote works but the intercom doesn't, the fault is likely in the intercom or its connection to the motor. If neither works, the problem is likely the motor or its power. We test the intercom and the motor together, because the fault can sit on either side. Once we find it, we tell you the cost before any parts are ordered.

Do you repair complex intercoms?

Yes. We repair multi-unit intercoms for complexes, estates, apartment buildings and office parks. When the gate panel fails, every resident loses the intercom at once, so visitors and deliveries can't reach anyone. The most common faults are damaged gate panels, failed power supplies, lightning damage, faulty handsets in individual units and cable problems. We test the gate panel first, then trace any fault through to the affected units. Tell us it's a complex when you send your message, along with the make if you know it and how many units are affected. Photos of the gate panel help us bring the right parts. A service level agreement gives complexes regular servicing and 24-hour access to our technicians, so a failed panel doesn't wait.
