See and speak to whoever is at the door before it opens — from reception, from an upstairs office, or from a mobile on the other side of town. We install new door entry systems and repair the ones that have stopped answering.
Wired systems are the workhorses: a door panel, a power supply, handsets or monitors inside, and cabling in between. Nothing to charge, no signal to drop, decades of service life. If you are refurbishing, already have containment, or the run from door to desk is short, wired is almost always the right answer — and the cheapest to keep running.
Wireless and GSM systems earn their keep where cable can’t sensibly go. A gatehouse a hundred metres from the office. A listed frontage nobody is allowed to chase. A yard entrance answered by whoever is on shift. GSM panels call a phone number rather than a handset — so deliveries get answered even when the building is empty, and the door can be released from a mobile.
Video adds certainty. An audio intercom tells you someone claims to be the courier; a video panel shows you the uniform, the van and the parcel. For premises with lone workers or cash on site, we consider video the default, not the upgrade.
We install and service systems from the established door-entry manufacturers — and because intercoms are half electrics, half door, the same visit can correct the closer, alignment or release that the panel is wired to.
Intercoms fail piecemeal: a handset that no longer buzzes the door, a panel button worn through, a hum on the speech line, a power supply that quietly died in a riser cupboard. Each of those is an individual fix. Before anyone sells you a new system, we diagnose which link in the chain has failed:
Wired wins on reliability and is the right call on new builds, refurbishments or short cable runs. Wireless and GSM systems win where cabling is impractical — listed buildings, gatehouses, split sites — or where the person answering is not always in the building.
Usually, yes. Failed handsets, door panels, power supplies and call buttons are all repairable or replaceable individually on most systems. We quote the repair first and only recommend replacement when parts are obsolete or the fault is in buried cabling that costs more to trace than a new system.
Yes — that is the point of door entry. The intercom is wired to an electric release or maglock, so reception, a flat, or a mobile phone on a GSM system can see or speak to the visitor and release the door. We install and maintain the lock side as well as the intercom side.
Yes. Multi-way panels with a handset or monitor per unit are a core use case — offices, serviced buildings and flats above commercial premises. We can also add trade buttons and keypad or fob entry alongside the intercom.
Send a photo and a short description of the fault and we’ll come back with a fixed-price quote the same day. Most diagnoses don’t need a site visit.
