Service and Maintenance
A door with worn gaskets can be very costly when trying to keep a room at a low temperature. We can service all types of Sliding, Hinged, Steel and High-Speed Doors, Roller Shutters and Sectional Doors to prevent these extra and unnecessary costs. We can replace Gaskets, Guide Rails, Handles, Locks, Hinges, Rollers and much more.
We can modify existing doors with upgrades like protective Kick Plates to prevent damage to your door leaf. We can also fit new heaters to Hinged doors in a freezer environment.
We can replace damaged door leaves or supply an entirely new door complete with frame if needed.

Damaged gasket due to heater being turned off and door leaf freezing up

Door damaged by impact
Impact Damage
Doors do not fail simply because of wear and tear. Quite often we are called to site after a collision with a Forklift Truck or a wagon has led to severe damage of a door or loading bay area. Quite often this damage can prevent the door or dock leveller etc. from working properly. We can assess the safety of the existing products while taking measurements for replacement parts. We will try to match the colour of the existing products or the surrounding area if it is colour coded.
