About bifold doors.

Bifold doors are doors that fold back together and are fully glazed. When you have 3 or more doors, you may also have a main traffic door. It is very common to need a bifold door repair.

Bifold doors can often become problematic and you might find yourself needing your bifold doors repaired.

The most common problem with bifold doors in need of repair is a service and realignment. Due to the nature of bifold doors they often drop out of alignment. Realigning your bifold door when they drop out of alignment is very important. You should not ignore this problem. Bifold doors can drop out of alignment due to wear and tear over time. Bifold doors also drop out of alignment if the glazing has not been fitted correctly. If you do not resolve the issue promptly you might end up needing a bigger bifold door repair.

Bifold Door Realignment.

When your bifold doors drop out of alignment you might notice a number of issues. The bifold door might scrape along the bottom of the frame. There might be a gap at the top of the doors and the bifold doors could become draughty. When the bifold doors catch, this can dislodge the rubber gaskets. The door locks might no longer line up and you might find it difficult to lock the doors. If you have any of these issue you should call DWLG and book a bifold door repair.

Once your bifold doors have dropped out of alignment, a number of other issues might occur if you do not address the issue. When the doors drop out of alignment it can cause stress on other components of the doors. Below we will run through a few of the bifold door repairs you might end up needing.

Broken bifold door handle – main traffic door.

When the bifold doors drop out of alignment they can become stiff and you may struggle to lock the main traffic door. You might find yourself lifting the door to be able to get the doors to lock into place. Over time if you keep doing this you risk breaking the multipoint lock or the handle on the main traffic door.

You will then need a bifold door repair that would include a new handle and or multipoint lock. Bifold door locks are made for the specific brand of doors. DWLG will contact the manufacturer to source the correct lock needed. We would need to come over, remove the lock and take detailed pictures of the lock to make sure the manufacturer send us the correct replacement bifold door lock.

DWLG would replace the lock for you and also fully service and realign the doors to help prevent future issues with the bifold doors. DWLG can carry out a bifold door repair on all bifold doors.

Broken bifold door handle on the intermediate/middle door.

Another very common issue is a broken bifold door handle on one of the middle doors.

This can happen for a few reasons. The most common reason is that the lock/ gearbox behind this handle has broken. The handle will be stiff to use. When excessive force is used the handle will snap, you will then need a bifold door repair.

The handle could also be stiff if the doors have dropped out of alignment and the lock becomes misaligned. This is why it is important to get your doors realigned when they drop. If this happens you will need you will need your bifold doors repaired including a new handle and possibly a new shoot bolt gearbox mechanism. DWLG would give your doors a full service and realignment, replace your broken handle and gearbox if needed. We carry 95% of parts onboard. DWLG stock the most common parts you might need.

Bifold door will not open or is catching.

You may open your bifold doors one day and find they are catching at the bottom. This could be due to a broken lock.

The intermediate doors contain shoot bolt lock. Shoot bolt locks are where you turn the handle 180 degrees and a lock will move 2 shoot bolt rods. The shoot bolt rod will move into the top and bottom of the frame. Once the gear box has broken you may find the bottom rod does not contract back into the doors and it becomes caught on the bottom of the frame. You may also find the top shoot bolt may no longer pop out of the top of the door and lock into the frame, this will cause the doors to be loose at the top. DWLG would come over and fully service and realign the doors. We would also replace the broken gearbox. DWLG stock gearboxes to suit 95% of doors.

Broken bottom roller hinge.

There are a number of reasons a bottom roller hinge can break. Over time the washers between the hinge section can perish causing the doors to slightly drop out of alignment. this can then in turn snap or bend the hinge.

The most common reason the bottom roller hinge breaks is because the doors have dropped out of alignment. Once the hinge breaks this can cause a number of issue. The doors can become unsafe and wobble. The doors may no longer be able to open and close. This broken bottom roller can also put extra pressure on other parts of the door causing them to break too.

It is very important that the correct roller for the brand of doors is used when your bifold door is repaired. Every manufacturer uses specific roller hinges designed for their brand of door. You can not use a roller hinge from one manufacturer on another door as it will not work or fit.

Replacing Bottom Roller Hinges.

When DWLG repair your bifold doors we will make sure we come with the correct roller hinge needed, we do this by making sure have stock of 95% of parts, but we also double check by requesting pictures from yourself to make sure we have this hinge in on board on the day.

Although we carry most hinges onboard. Some roller hinges are special orders and will need to be ordered in from the manufacturer.

When your bottom roller hinge breaks you will need a bifold door repair including a full service and realignment of the doors and a replacement bottom roller hinge. It is important to always have your doors serviced and realigned when you replace the hinges. Not realigning the doors will mean the hinge will more than likely snap again.

Bifold door perished or missing gasket.

When your bifold doors drop out of alignment they can start to catch on the seals at the bottom or the door or the door frame. Over time the rubber gasket seals will begin to catch and be pulled out of the correct position. The seals may also carry on catching and cause damage to the gaskets. The gasket seals will then requiring replacing when you have your bi-folding door repair carried out.

Once the gaskets starts to perish or they have come out of the bifold doors, the bifold doors may become draughty. When it rains your bifold doors might let water in. This is because there is no longer a seal at the bottom of the doors.

Replacement bifold door gaskets.

DWLG can replace your damaged rubber gaskets. On one set of doors you may find as many as 5 different types of gasket.

The top/bottom of doors, sides of doors the top and bottom of the frame are where the gaskets are located. If you needs the gaskets replaced it is important to find out where the gaskets need replacing on the doors. We can then make sure we have the correct type.

We do carry the most common types of gaskets but sometimes need to order gaskets in from the manufacturers.

If the gasket is not damages we are able to re-fit the old gasket for you.

When DWLG carry out a bifold door repair where we replace the gasket. We will also service and realign the doors so they stop catching preventing further issues.

Bifold door main traffic door catching.

On a set of bifold doors with 3 or more doors it is common to find a main traffic door. This allows access through just the 1 door. Main traffic doors saves you having to open up the full set of bifold doors all the time. This will mean less wear and tear on the folding doors and extend there life.

The main traffic door will have the most wear and tear as it will have the most use. It is common for this door to start to catch or drop out of alignment from the fold back doors.

This can happen because of frequent use. A common problem when the main traffic door starts to catch is that the hinges have perished and would need replacing.

When this happens you would need a bifold door repair where we would replace all 3 hinges on the main traffic door. We would then service and realign the full set of bifold doors.

Bifold door repair – service and realignment

DWLG service and realign you bifold doors with every bifold door repair. This is because nearly all problems with bifold doors are cause by the doors being misaligned. Bifold door glass will be removed then refitted making sure the glass has been “toe and heeled”. All mechanical parts are checked cleaned and lubricated. DWLG check your hinges to make sure they have the correct fixings. The bifold doors are adjusted so they all line up correctly and run smoothly. DWLG often come across doors where the incorrect fixings have been used in the hinges. This can causes the doors to drop out of alignment, it can also make the doors dangerous to use.

Replacement toughened double glazed glass unit in bifold doors.

Bifold doors contain very large glass units. Toughened Safety glass must be used when replacing bifold door glass units. When the toughened glass breaks it will break into small squares and is less likely to cause injury.

You my need a bifold door repair to replaced the glass units for a couple of reasons.

Over time you may notice that there is a build up of condensation between the 2 panels of glass. This happens when the double glazed glass unit “blows” the seal around the glass perishes. This allows air and moisture in between the 2 panels.

Another reason you may need a bifold glass replacement is because the glass has smashed. The most common cause of this is when cutting your grass and a stone will hit the glass breaking it.

A less common reason for you to need your glass unit replaced is because it can spontaneously break. This has no known cause.

Toe and Heel Bifold Door Glass.

When getting your bifold door glass replacement it is important you make sure the glass unit is “toe and heeled” . If the glass is not toe and heeled back into the doors it can cause problems. Incorrect fitting can cause the doors to drop out of alignment and cause other issues.

DWLG sometime come across bifold doors which have been fitted with triple glazing. Triple glazing is very heavy and can cause a lot of pressure on your bifold doors. The pressure can make the doors misaligned more often. The extra force of the triple glazed glass can make your bifold parts wear quicker.

DWLG would not recommend the use of triple glazed glass on bifold doors. It can cause the doors to have issues more frequently due to the weight of the glass.

How long does it take to repair a bifold door.

The time it takes to repair a bifold door will differ from set to set.

Wooden doors typically take longer than Aluminium or upvc.

A 3 door bifold door set usually takes 1-2 hours to repair. Each additional door will add 30-45 min to the repair.
