Top centre pivot replacement and structural realignment

Commercial Door Maintenance and Security Ltd was instructed to attend a Grape Tree branch in Sudbury following issues with the operation of their double aluminium entrance doors. The transom unit serving both doors had failed, resulting in poor control, inconsistent closing action, and increased strain on the door leaves and surrounding framework. As the entrance serves a busy retail environment, it was essential to carry out a permanent repair that would restore both functionality and safety while minimising disruption to daily trading.

To complete the repair correctly, a full transom replacement was required. Both aluminium doors were carefully removed to allow safe access to the existing transom assembly. The failed unit was removed in its entirety and replaced with a new, correctly specified transom system designed to handle the weight and usage demands of double commercial doors. Precision alignment and fixing were critical at this stage to ensure the new transom would operate smoothly and evenly across both door leaves.

“True security starts with precision. When alignment, structure, and control work together, a door becomes more than an entrance – it becomes a reliable safeguard for the space it protects.”

Enhancing security, performance, and reliability in a busy commercial setting

As part of the wider repair, works were also carried out to the automatic door system. This included the installation of a new drive arm and associated components to restore consistent and controlled door movement. Fixing points were adjusted to increase clearance where required, allowing additional security hardware to be fitted centrally to the door. These adjustments were completed with precision to ensure compatibility between the mechanical door operation, locking mechanisms, and access control systems.

Following completion, the door was refitted, fully aligned, and tested to confirm smooth operation, correct locking engagement, and reliable automatic function. The entrance was left in good working order, providing Bloc with a secure, compliant, and professionally functioning door system suited to a busy commercial environment. This project demonstrates Commercial Door Maintenance and Security Ltd’s expertise in complex aluminium and automatic door repairs, combining mechanical precision with security-focused solutions.
