Look beyond the speed setting
The closer, hinges, latch and frame work together. An adjustment may not solve worn hardware or a door that binds, and a leaking unit may need replacement. Any planned change must take account of access needs and the door's safety role. Ask what will be checked at handover, including closing from different opening positions where appropriate.
The assessment for hydraulic door closers
We consider the door weight, closer setting, fixings and latch action together. Fire-door function and access requirements need appropriate assessment.
Information to prepare
Describe slamming, failure to latch, visible oil leaks or difficulty opening. Let us know if the door is a fire door or accessible entrance.
