Covering Caernarfon and nearby
Homes, businesses and public buildings throughout the LL55 postcode district can arrange sensor upgrades and replacement with us. We are the contracting party and organise every visit; the engineer, who works under our management, travels in to Caernarfon for the job rather than working from premises in town.
Libraries, health centres and council buildings in Caernarfon still need accessible entrances, whatever their size. A single automatic door with a push pad or touch-free switch is often enough to give everyone easy access.
Nearby towns we also list for sensor upgrades and replacement (straight-line distance): Bangor (8.3 miles), Holyhead (18.8 miles), Llandudno (22.1 miles), Colwyn Bay (24.9 miles).
What to think about for sensor upgrades and replacement in Caernarfon
- Rain, snow and blowing leaves can trigger radar sensors over exposed doors. Some sensors filter weather better than others, which the engineer weighs up when choosing a replacement.
- Sensor changes on escape route doors must never stop the door opening when it needs to. The engineer checks the door's escape mode after any sensor work.
- Care settings in Caernarfon often need longer hold-open times and wider safety zones for residents who move slowly, use walking frames or pause in the doorway.
- If several doors at one site have the same old sensor, replacing them together keeps the doors behaving consistently and may reduce the cost per sensor.
- Shiny, wet or newly polished floors can confuse infrared safety sensors. Mention any recent floor changes at your building in Caernarfon so the zones can be set for the new surface.
Sensor upgrades and replacement in Caernarfon: guide prices
The visit price is agreed in writing before an engineer attends; parts and any further work are quoted before they are done. Guide price: typically £195 to £495 ex VAT.
| Item | Guide price | Notes |
|---|---|---|
| Add or replace a safety or activation sensor | £195 – £495 | per sensor fitted, ex VAT |
| Touch-free switch or push pad | £145 – £395 | per switch, ex VAT |
| Side-screen or light-curtain protection | from £295 | per door, ex VAT; on survey |
Sensor prices cover the part, fitting and set-up. If a sensor is fitted on a visit of its own, the visit charge (from £95 ex VAT) is added, and we confirm the total in writing before an engineer attends. Each sensor is set up for the door and tested before the engineer leaves.
Standards and rules in Wales
Workplace law (the Workplace (Health, Safety and Welfare) Regulations 1992) expects powered doors to have suitable and effective features to stop them trapping anyone and, where needed for safety, to open by hand unless they open automatically if the power fails. Doors at work must also be kept in efficient working order under a suitable system of maintenance. HSE guidance on those regulations says the frequency of maintenance depends on the equipment and the manufacturer’s information.
No law sets a fixed service interval. We recommend that a trained engineer checks the safety functions at least once a year, with service intervals set by the manufacturer’s instructions and how heavily the door is used, and that someone on site carries out simple regular checks and keeps a record.
How it works
- Share the details. Send the address in Caernarfon, the door type and make if you know it, and a description or video of the problem. For servicing, tell us how many doors there are and how busy each one is.
- Price confirmed in writing. We agree the visit price in writing before an engineer attends. Some straightforward repairs can be priced in full from photos and the make and model of the door.
- Diagnosis and repair. A specialist engineer attends on the agreed date, finds the cause, repairs or services the door, and tests its operation, sensors and safety functions with reference to BS EN 16005.
- Written record. Each visit ends with a written record for your files. Anything still outstanding, such as parts on order or recommended upgrades, is quoted before any further work is done.
Ask for a price on new safety or activation sensors in Caernarfon. Each one is set up for the door's hazard zones and tested before the engineer leaves.
Sensor upgrades and replacement in Caernarfon: questions
Will you record the sensor settings for our building in Caernarfon?
Yes. The job report lists each sensor fitted, its position, the settings used and the test results. Keep it with your service records, as it helps future engineers and shows the door's safety set-up was checked after the work. The same details are useful if an insurer or inspector asks.
What will sensor upgrades and replacement in Caernarfon cost?
Our guide is £195 to £495 excluding VAT (per sensor fitted), the same guide prices we use across the UK. We agree the visit price in writing before an engineer attends in Caernarfon, and quote any parts or further work before doing them. The price guide lists typical repair and service costs.
Can a risk assessment in Caernarfon tell us which sensors we need?
Yes. A safety inspection tests each hazard zone and records where sensor coverage is missing or poor. The report then lists the sensors or light curtains needed, and we can quote those items exactly as listed, or you can pass the report to another competent installer.
Can you upgrade sensors on an old door in Caernarfon?
Most older doors can take modern sensors. A few very old controllers cannot monitor current safety sensors. If yours is one of them, we explain whether a controller upgrade or a new drive unit is the better option, and quote it, before any work is done.
How often should automatic doors in Caernarfon be serviced?
No law sets a fixed interval. We recommend a trained engineer checks the safety functions at least once a year, with service intervals set by the manufacturer's instructions and how heavily the door is used; busy doors are often serviced more often. Site staff should also carry out simple regular checks and keep a record of them.
Are parts quoted before they are fitted?
Always. If a repair or service in Caernarfon needs parts, such as rollers, belts, sensors, a control board or a motor, we quote them in writing first. Some common parts may be on the engineer's van; others are ordered once you accept the quote and fitted on a return visit at a price already agreed.
Who is responsible for automatic doors on escape routes in Caernarfon?
The responsible person under the Regulatory Reform (Fire Safety) Order 2005. Automatic doors on an escape route need fail-safe opening or break-out, and sliding or revolving doors must not be used for exits specifically intended as emergency exits.
