How To Tell If Your Special Doors Need Replacing

There’s no denying the importance of Special Purpose Doors, they are crucial for providing protection and insulation in numerous industrial, commercial and residential applications. Problems can arise if doors are not functioning at their full capacity, which can be caused by wear and weathering or could be due to common mistakes that businesses make that damage doors.

If doors are damaged or altered they man no longer be compliant, and could pose as a problem for occupants. For example, a sound insulated door without a proper door seal may cause noise complaints, or a dysfunctional fire door could cause smoke and flames to spread within a building.

To ensure that your doors continue to operate at their full capacity it is important to be able to recognise the signs that Special Purpose Doors need replacing. Here’s what to look out for.


Do your Special Purpose Doors creak or groan when they open and shut? This could be a sign that their hinges are no longer in proper working condition and may point towards issues such as corrosion. If your doors begin to scrape or squeak, they will likely only get worse so it’s best to arrange an inspection as soon as possible.

Difficult to Open

Special Purpose Doors such as Fire Doors and Sound Insulation doors may be heavy in their own right, but if you begin to notice more resistance than usual, this may also be a sign that they are beginning to wear, and may require attention.


Special Doors are built to last, however over time, they may take damage, especially if they are used in a high traffic location or industrial purpose. Dents and scratches can become worse, and if the door is constructed from steel it may corrode, forming cracks within the door. Doors can also warp over time, which can compromise their functionality.

Delamination can occur between the composite layers that make up the inner and outer layers of special purpose doors, this can be due to cyclic stress or continual exposure to the elements, and if the core becomes damaged the door will need replacing.
Inspect You Doors Seal

Proper door seals are crucial for many types of Special Purpose Door. In fire doors, they prevent smoke from spreading throughout a building and in Sound Insulated doors they stop sound from escaping. Seals also help to keep inside temperatures stable in buildings that use air conditioning, however, seals may degrade over time, so it’s important that you check that they are still functioning.

If you can see light penetrating through the sides and the bottom of the door, or you can feel cool or warm air entering or exiting this may be a sign of your door’s seals not functioning correctly. To be sure try holding a flame near the gap in the door, if it flickers, this means that there is most definitely a problem with your doors seals. Another telltale sign is if your soundproof doors are letting more sound escape that when they were first purchased.

Signs of Moisture in Glass

Does your Special Purpose Door have glass panelling? It is possible for moisture to become trapped within double-paned glass in older doors, which if left unaddressed can lead to mould and rot. If attended early panels may be able to be replaced.
