​

Bifold doors are a fantastic way to bring light, space, and style into modern homes. But like any moving system, they rely on multiple components working smoothly together. Over time, everyday use, weather exposure, or poor installation can lead to faults that stop your doors from sliding or locking properly.

​

Our specialist bifold door repair service is designed to diagnose and fix all common issues quickly and effectively. Below is an overview of the main types of work we carry out and what you can expect from our service.

​

Roller and Track Repairs

 

The rollers and tracks are the heart of any bifold door system. If they wear down, bend, or become clogged with dirt, the doors can stick, scrape, or jump off their guides. We commonly:

​

• Replace worn or broken rollers with high-quality replacements

• Realign or adjust tracks to ensure smooth running

• Clean, lubricate, and service the running gear to prolong life

​

This work restores effortless opening and closing, even on heavy or older door sets.

​

Alignment and Adjustment

 

Misalignment is one of the most common bifold door problems. Panels can shift out of place due to movement in the property, ground settlement, or repeated heavy use. Symptoms include draughts, uneven gaps, or doors that don’t sit flush when closed.

Our engineers:

• Adjust hinges and tracks for perfect alignment

• Re-set panels so they seal tightly and operate correctly

• Check frame fixings and correct any movement

• ​

Toe and Heel – Why It Matters

 

One of the most frequent causes of bifold misalignment is incorrect toe and heel support. Bifold door panels are large and heavy, and without the right internal bracing, the weight of the glass and frame will naturally drag downwards over time.

​

Toe and heel refers to the diagonal bracing technique used inside the door sash, where packers are placed at opposite corners (top hinge side and bottom lock side). This balances the load and keeps the door square within its frame.

​

If toe and heel packing is missing or has been done incorrectly:

​

• The door may drop on the handle side, making it difficult to close or lock

• Gaps can appear between the panels, allowing draughts or water ingress

• The locking mechanism can fail due to misalignment

• Over time, the structural integrity of the door set is compromised, leading to more serious faults

• ​

Correct toe and heel adjustment is vital to the long-term performance of any bifold door system. It ensures the doors remain properly supported, aligned, and secure.

​

Lock, Handle and Hinge Repairs

 

Security is essential. Faulty locks, stiff handles, or worn hinges can leave your doors insecure or difficult to operate. We often:

​

• Repair or replace broken locking mechanisms

• Upgrade locks to modern 3-star anti-snap cylinders for added security

• Replace damaged or corroded hinges and handles

• Adjust strike plates and keeps to ensure smooth locking

​

Seal and Gasket Replacement

 

Over time, rubber seals and gaskets perish or shrink, allowing draughts and water ingress. As part of our service, we:

​

• Replace worn gaskets and weather seals

• Fit new brush or compression seals where required

• Test the doors for a snug, weatherproof closure

​

This improves insulation, reduces energy loss, and keeps your home comfortable all year round.

​

General Servicing and Maintenance

 

Prevention is always better than cure. As well as targeted repairs, we provide routine servicing that extends the life of your bifold doors.

This includes:

​

• Cleaning and lubricating all moving parts

• Tightening fixings and hardware

• Checking seals and weatherproofing

• Identifying small issues before they become costly problems
