Automatic Door Repair Harlington

Welcome to Automatic Door Repair UK, the leading specialist in **automatic door repair services for Harlington**. In today's fast-paced commercial environment, a reliable, safe, and fully functional entrance is not just a convenience—it is a critical necessity. Whether you operate a busy retail store, a corporate headquarters, a healthcare facility, or a hospitality venue in Harlington, a breakdown in your automatic door system can cause severe disruption, compromise security, and impact accessibility for your customers and staff.

Our team of highly skilled, **BS EN 16005 accredited engineers** is strategically positioned in and around Harlington to provide rapid response times for all emergency repairs and scheduled maintenance. We specialise in the diagnosis, repair, and servicing of all major automatic door brands, including **Dorma, Record, Geze, Assa Abloy, and Tormax**. From sliding doors that fail to close to swing operators losing hydraulic pressure, we possess the deep technical expertise to resolve your issues quickly, safely, and cost-effectively.

Advanced Fault Finding & Electronic Repair

In Harlington, we frequently encounter automatic doors that behave unpredictably due to sensor conflicts, power fluctuations, or component degradation. Our engineers are trained to troubleshoot complex **logic board failures** and input/output circuit issues. We rigorously test the **battery backup units** to ensure the door fails safe in the event of a mains power cut, and we verify the integrity of the **electric locking systems** (maglocks or strike releases).

For older installations in Harlington, mechanical component fatigue is a common cause of failure. We inspect the bottom guide channels for accumulated debris and wear, which is a leading cause of motor burnout. By addressing these underlying mechanical issues during our visit, we extend the operational lifespan of your operator and prevent costly premature replacements.

Mandatory Safety Checks & Upgrades for Harlington Businesses

As a building manager or owner in Harlington, you have a legal duty of care to ensure your automatic doors are safe for public use. We help you meet this obligation with rigorous compliance checks. Our safety audits involve testing the **breakout functionality** for emergency escape routes and ensuring that **side screen safety sensors** are active and correctly positioned.

If we identify a high-risk failure in Harlington, such as a blind spot in the sensor field or a defective reverse-on-obstruction mechanism, we will advise on immediate remedial action. We install state-of-the-art combined radar and infrared sensors that offer superior pedestrian protection compared to older technologies, ensuring your doors stop immediately if a person is detected in the threshold.

Common Automatic Door Faults We Fix

In Harlington, we frequently resolve issues such as:

• Door stuck open or closed: Often caused by dirty sensors or power failure.
• Noisy operation: Indicates worn floor guides or motor bearings.
• Erratic movement: Usually a sign of encoder errors or belt slippage.
• Failure to lock: We adjust electric strikes and maglocks for secure locking.

The Value of Planned Maintenance in Harlington

Reactive repair is often more costly than proactive care. We recommend our **Planned Preventative Maintenance (PPM)** service for all businesses in Harlington. Regular servicing (typically twice a year) allows us to clean the bottom guides, tighten drive belt tension, and lubricate the gearbox. This prevents the common 'grinding' failures we see in Harlington and significantly extends the lifespan of your expensive automatic door assets.
