Need Your Bifold Doors Realigned in Northwood HA6?

Bifold doors can become misaligned due to many factors. We repair & refit the following to realign your bifold doors. Loose Hinges • Worn Trolleys • Poorly Fitted glass • Movement Of The frame Or Threshold  Often poorly fitted glass is the cause of doors dropping & scrapping. The weight of the glass moves to one side of the door and this causes the door to catch the bottom track. Making it very hard to open and close your doors. Correct fitting of the glass prevents this and should be done at the initial installation. Unfortunately general builders often fail to do this. This procedure is called toe & heeling and involves correct positioning of packers to stop any movement of the glass. Hinges & trolleys also move or become worn and this will also cause the doors to drop. We repair & replace all bifold hinges & trolleys.

Need Your Bifold Door Locks Repaired in Northwood HA6?

When bifold doors become misaligned,the locks will usually fail shortly afterwards. Most bifold door locks operate a top & bottom rod. These rods are usually operated by turning a handle from 12 to 6 o'clock. When the door is out of alignment excessive pressure will be applied to the bottom rod. This will cause the lockcase (where the handle is,see lockcase image) to break. The rod will then not retract when the handle is turned. Sometimes the handle will break due to a design feature to prevent excessive force being used in an attempted burglary. It is vital to service bifold doors to ensure you do not need to replace bifolding door mechanisms.  Multipoint locking mechanisms are also used. Locking top, bottom & centre,often with rods and hooks (see multipoint lock image). These too become misaligned with the frame(strike plates) and cause the handle and lock to be stiff. These are usually operated by lifting the handle from 9 to 12 or 3 to 12 depending on the handing of the door. Then pushing down to open the door. We realign the door so that the lock operates smoothly. Maintenance of bifolding doors is crucial to stop expensive bifold door lock replacements.

Poorly fitted or worn bifold door hinges will prevent the bifold doors from operating correctly. We replace bifolding door hinges that have become worn or have snapped due to poor installation. We will always try and adjust them first but that is not always possible. The bifolds run across the track on what are known as trolleys. These can be fitted top & bottom and adjusting these affects the height of the doors. If they are too high or low the doors will drag on the bottom or top track. We have a lot of experience in adjusting these to the right setting. Allowing for movement due to weather or wear and tear. Which is why we are happy to guarantee our work for a minimum of one year.

Bifold Door Realignment in Northwood HA6?

What does bifold door realignment involve ? What do we do when realigning bifold doors in Northwood HA6.

1)We first check hinges & trolleys to make sure they are not worn too much. Washers and wheels can ware out and cause the bifold door to drop or not run smoothly.

2) We then check the glass has been correctly packed out. Toe & heeled correctly. Using the correct packers in the right position . If this is not done right the glass will move within the frame and this will cause the door to go from a rectangle to a parallagram. The door drops to one side and this then causes several issues, see below.

3) The door catches the bottom of the frame. Ripping rubber gaskets and making it difficult to close the door. Needing a lift to get it shut.
4) The locks are then misaligned with the door jamb and strike plates. Putting pressure on the locking mechanism, resulting internal damage in the bifold door lock.
5) Excessive force may then be used and the handle will snap or become rounded off.
6) The bifold door can then pivot on the bottom frame and crack the hinge.
Getting your bifold doors realigned in Northwood HA6, can save future costly repairs.
