SOME OF THE MANY TYPES OF BIFOLD DOOR WE REPAIR:

How long will Sunflex Bifold Door repairs take?

Repair times vary depending on the issue, but most Sunflex bifold door repairs can be completed the same day.

Minor adjustments, such as alignment or lubrication, usually take 20–30 minutes.
Hardware repairs — such as replacing rollers, hinges, or locks — can take 30 minutes to 2 hours, depending on parts availability.
If specific Sunflex components need ordering, we’ll secure your door and arrange a next-day delivery where possible.

Sunflex Bifold Door Isn’t Locking – Would Integrity be able to help with this?

Absolutely. Our engineers regularly repair Sunflex locking systems and alignment issues. We understand the precision engineering behind Sunflex doors and carry compatible replacement parts for most models.

We’ll diagnose the issue within minutes and carry out the repair to get your door locking and operating like new again.

How much do Sunflex bifold door repairs cost?

Costs vary depending on the fault and parts required.
For example:

Alignment or servicing starts from a standard callout rate.
Gearbox or lock mechanism replacements typically take an hour of labour plus parts.

We’re happy to provide a quote from photos or a brief description, and we’ll always confirm costs before starting any work.

Want to Save Money With Sunflex Bifold Door Repairs?

Don’t wait until the issue worsens — if your door starts to feel heavy, sticks along the track, or the handle becomes stiff, it’s best to get it checked early. A quick service or alignment can often prevent more expensive repairs later.

Why Do Sunflex Bifold Doors Seize or Jam?

Sunflex bifold doors can seize or jam for a few common reasons:

Expansion and contraction due to temperature changes can cause panels to tighten within the frame.
Worn rollers or hinges can make the door difficult to glide.
Misalignment — even by 1mm — can stop a door from locking or closing properly.
Age and lack of lubrication can cause the locking mechanism to seize.

Frequently Asked Question's

What types of Sunflex bifold doors do you repair?

We repair and service all Sunflex systems, including the SF55, SF75, and SVG30 models. Whether it’s aluminium bifolds or sliding Sunflex doors, we can restore smooth operation and alignment.

My Sunflex doors are stiff and won’t slide properly — what could be the problem?

This is often caused by misalignment, dirt in the track, or worn rollers. We’ll inspect your system, clean the runners, and adjust the doors to glide freely again.

Can you fix a Sunflex door that has dropped or won’t close properly?

Yes — dropped doors are one of the most common issues. Our engineers can realign the panels, replace worn hinges or rollers, and ensure the door locks and seals perfectly again.

Do you use genuine Sunflex parts?

Yes. We carry a range of Sunflex hardware and can order genuine components directly if required, ensuring a long-lasting, reliable repair

How much does a Sunflex bifold door repair cost?

It depends on the issue. Minor adjustments and servicing are affordable, while more complex repairs such as replacing a gearbox or lock mechanism will take longer. We’ll always provide a clear quote before starting work.

Can you repair Sunflex bifold doors in one visit?

In most cases, yes. We keep common rollers, hinges, and locks in stock. If specialist parts are needed, we’ll secure your door and return as soon as they arrive — often the next day.

How often should Sunflex bifold doors be serviced?

We recommend a professional service every 12–18 months, especially if the doors are used daily. Regular maintenance prevents wear, protects the mechanisms, and keeps them running smoothly year-round.

Do you charge a callout fee for Sunflex repairs?

No — we never charge a callout fee. You only pay for the repair or servicing work completed, with no hidden extras.

My Sunflex door won’t lock — is it safe?

If your door won’t lock, avoid forcing it. The mechanism may be out of alignment or jammed. Contact us as soon as possible, and we’ll make it secure and repair the cause of the issue.
