Top tips for looking after your bi-folding door

You’ve had the bi-folding door installed and it’s looking fantastic. You’ve invited all your friends and neighbours around to admire it. You’ve opened it up to show just how simple it is to pop outside, and you’ve watched the sunrise – or the stars – from the comfort of your sofa on a frosty day.

It’s lovely, isn’t it?

Here’s how to keep it that way.

Cleaning the frames:

Wash the frames with a mild detergent solution, using a soft cloth. Don’t use abrasives or solvents, wire wool or brushes.

You’ll soon find out how often you need to do the job. If you live in an area with lots of traffic fumes for example, or in a particularly exposed or windy spot, you may need to do the job more frequently.

Cleaning the glass:

With a lot of surface area to be cleaned, hopefully you’ve got a professional window cleaner for the outside. If not, get yourself a squeegee!

Inside surfaces can often get smudged by fingerprints, especially if there are children at home. Try a proprietary brand of glass cleaner – or a mild vinegar solution – and the old-fashioned, but very effective, method of using scrunched up newspaper.

Glass is tough but it can get scratched. If you wear rings, it might be a good idea to remove them before you start.

Cleaning the tracks:

It’s important to keep tracks free of debris. A soft brush or vacuum cleaner should suffice.

Be careful if you’ve got a gravel area outside as loose stones can get trapped in the treads on your shoes and find their way into the tracks. If you notice any resistance when you try to slide your doors open or closed, check it out and remove the obstruction. Forcing a door could cause damage to the frame, track or roller mechanism.

Looking after the locks:

The shootbolts and moving parts of the locking mechanism should be lubricated with light machine oil.

Do not attempt to lubricate the lock cylinder which will already be packed with a protective grease.

Bi-folding doors are usually reliable and trouble free, but if you have any other problems or queries, you can always check with us or your installer.

If you’re feeling daunted, don’t be. Looking after a bi-folding door is very simple. To sum up:

  • Wash the frames
  • Clean the glass
  • Keep the tracks clear
  • Lubricate the locking shootbolts


  • Don’t use solvents
  • Don’t use abrasives
  • Don’t lubricate the lock cylinder

Okay, that’s the job done and your door is looking great again. It’s time to pop the kettle on, put your feet up and enjoy your beautiful surroundings.
