We were called to look at a dangerously closing aluminium door on the main entrance at the Royal Albert Docks Trust in London.

On initial inspection we found that the transom closer had failed and the door was closing without control slamming into the frame. This was obviously a concern to the staff and visitors as there could be a risk of impact and crushing. It was also apparent that the door had dropped making it difficult to lock and not close.

This required removal of the door to allow us to inspect the transom closer, so we carried out a risk assessment and deployed our yellow men barriers to designate a safe working area. Once the door was removed it was apparent that the closer seals had failed and had to be replaced.

We installed the new Dorma RTS85 closer, then refitted the door and checked the alignment with the seals and locks, adjusting where necessary. The door closer was tested for opening and closing, adjusting the closer for a smooth closing action.

Finally, we cleaned the door, glass and frame completing the repair and provided documentation as all of our work comes with a 12 months guarantee.
