How to Maintain Bifold Doors


Bifolding doors make a big impact in a home, usually in terms of a significantly improved rear aspect and in also terms of the valuation of the property. Simply put, a good set of bifold doors makes the living space that much more appealing to be in and increases the value of the home, as a result. High-quality bifolding doors should be properly maintained, however, because a set that has seen better days is just as likely to put potential buyers off than attract them. As with other window and door problems, it is always better to deal with potential trouble before it gets out of hand. The old adage that a few pounds spent earlier on will save you plenty of cash down the line applies with bifold doors. Having said that, uPVC and aluminium bifold doors are not very reliant on a regular maintenance regime and most people find that their doors go on for year after year with no work carried out.


When it comes to painted aluminium or uPVC frames, cleaning is not a big chore and is done really to keep them free from grime. A damp cloth with a little soap or washing up liquid is all that is needed to wipe off external dirt, but avoid scrubbing, especially around the glazing seals. Although steam cleaners are fine for the glass, these should not be used on delicate areas. To clean the track, simply run a dry cloth or a duster around it to pick up any particles.


In order to keep the bifolding mechanism of your doors working well, it is important that you actually open them fully once in a while. This allows any lubrication to reach every area of a hinge, for instance. Most installers will give you specific information on what sort of lubricant to use, because this can vary from manufacturer to manufacturer. They may also advise of exactly where to apply it, too. However, if you don’t have specific instructions, then a little WD-40 or similar non-abrasive lubricant applied at the hinges, runners and locks usually does a very good job indeed of keeping bifolding in good working order.

Hinge Considerations

Whenever a bifold door is opened or closed, it is a good idea to get into the routine of watching the glazing panes carefully. For example, should you see a glazing section twist or look like it is leaning when the frame is either pushed or pulled, then it could be a sign that a hinge has loosened. In other cases, it might be that there is a dent in the runner or that hinge has a missing screw.

Overcoming a Blockage

At times, bifolding doors get stuck in a partially opened position. Even when properly lubricated, you may feel resistance at certain points as you open and close the doors. This is usually because something has become lodged in the lower running channel and prevents the doors’ roller from passing through easily. Try to fish out any dropped items that may have fallen in. The narrow attachment of a vacuum cleaner is usually ideal for the job of sucking unwanted items out.

Security Concerns

Bifolding doors are usually great in terms of home security, but for your complete peace of mind it is a good idea to check the handles, locks and other fittings once in a while. Make sure that they are securely attached and have not become loose in any way. You should also make a visual inspection to confirm that all of their screws are present.
