What does a door closer do?

A door closer controls how a door closes after it has been opened. A correctly selected and adjusted closer helps the door close steadily and reduces slamming.

Door closers are used on apartment building entrances, business premises and office doors, among other locations. Reliable operation depends on a closer that suits the door and on properly functioning hinges, locking hardware and strike plate.

When does a door closer need adjustment or replacement?

Have the closer checked if the way the door closes changes or the door becomes difficult to use. Common signs include:

The door closes too quickly or slams.
The door stays partly open or fails to latch.
Opening the door feels unnecessarily heavy.
Closing is uneven or jerky.
The closer, arm or fixings show visible damage.
Oil is leaking from the closer.

Adjustment cannot resolve every problem. A damaged closer may need replacing, while door alignment, seals or locking hardware can also prevent proper closing. We assess the cause before recommending the work.

Choosing a closer that suits the door

The choice of closer depends on factors including the door’s width, weight, construction, frequency of use and available installation space. The needs of the people using the door and the force required to open it also matter.

We check how the closer can be fitted to the door and frame, and whether existing fixings can be reused. Wooden, metal and glass doors may require different mounting solutions. Suitability is assessed before installation.

Installation and closing adjustment

We install the agreed closer and adjust its operation using the settings available on that model. We check closing speed, the final stage of closing and whether the door latches correctly.

The aim is controlled closing without unnecessary slamming. We then test the door and check whether other work, such as hinge or lock adjustment, is also needed.

Doors in housing companies and business premises

Shared entrance doors need to work reliably through repeated use. A poorly closing door can create noise or leave an entrance unintentionally open. We check how the closer, door and locking hardware work together.

If the door is a fire door or has other specific requirements, let us know when contacting us. The closer and installation method need to suit those requirements. A hold-open function is not assumed to be appropriate for every door.

How much does door closer installation or adjustment cost?

The price depends on the selected closer, door construction, required mounting components and scope of work. Adjusting an existing closer, replacing it and fitting a closer for the first time involve different amounts of work.

When requesting a quote, describe the door, the existing closer’s make or model if known, and any symptoms you have noticed. We agree the scope and price before starting. Any additional work is agreed separately.

Door closer installation FAQs

Can a slamming door be fixed by adjusting the closer?

Adjustment can often help if the closer is in good condition and suitable for the door. A damaged unit or a problem with other door components may require different work.

Why does the door stay partly open despite having a closer?

Possible causes include the closer’s settings or suitability, door alignment, resistance from seals or the operation of the latch and strike plate. We assess the complete door before recommending a solution.

Can a closer be fitted to an old door?

Often, yes, but the door’s construction, condition and mounting options need checking. Some installations require additional mounting components or other modifications.

Can an oil leak be fixed by adjusting the closer?

An oil leak may indicate damage that adjustment cannot resolve. We assess the closer’s condition and whether replacement is needed.

Will the closer make the door harder to open?

A closer adds resistance when opening the door. Choosing suitable equipment and settings helps balance closing performance with ease of use. Tell us about any accessibility needs when discussing the installation.

Does a door closer open the door automatically?

A standard door closer controls closing; it does not open the door for the user. Automatic opening requires a separate door operator system.
