Double Glazing Locks Repair

If a double-glazed window does not shut, it creates drafts that allow heat to escape. It also reduces the security of your home and exposes you to burglary.

Double glazed window seals, hinges and handles may break down over time. If this is the case, it could affect the way your windows function and invalidate any warranty you may have.

The locks are not working properly

Many people install anti-burglar devices on their main doors and gates However, they tend to overlook that windows are the most frequent targets for burglars. A poor lock can cause drafts inside the house, allow valuable heat to escape and also weaken your home's security.

If you notice that your uPVC window locks aren't working, there is a good chance that the lock mechanism has become stuck. This is usually due to a slit in the gearbox component. This can cause the handle to rotate 360 degrees, but not fully open. This is a problem that is common with uPVC windows, however it can also occur in tilt-and turn windows and sliding sash windows.

In this situation you can unlock the lock by applying pressure on the lever handle. This can allow you to free the gear box and allow the opening of the window. If this does not work, you may need to replace the window lock mechanism entirely.

Most modern uPVC windows use espagnolette locks. They are a locking system inside the window that secures the window utilising mushroom-like locking cams that are built into the frame. The handle controls the gearbox that then triggers the cams to either move upwards or downwards. A common issue is when the spindle on the lock has been damaged, causing the handle to turn freely but not move the window open or close.

A faulty transmission can also make your window appear to be locked, but it is not. This could happen when the centre rods, also known as crocodile tooth fixings, within the gearbox break off. Misty Glaze will supply and install replacement rods if this happens.

It is crucial not to force a stuck or broken lock. This can cause the lock to snap or break - especially with a uPVC window because it expands and expands as it warms and cools. To avoid this, it is best to call a locksmith professional to determine the problem and fix it.

Sticky Doors/Window

It's a nuisance to have windows and doors that are stuck and sag, but they can also be indicative of more serious structural problems. If you're having difficulty to open or close a window or door it is crucial to seek help from a professional whenever you can. The problem could result from a variety of causes like foundation settlement or an absence of support for the crawl space.


Humidity or frame problems could cause windows and doors to become stuck. If your frames are wood for instance, they can become brittle when exposed to moisture. Even if the hardware looks nice, it can make it difficult to open and close your frames. The wood swells when this happens, and it is pushed up against the hinges, causing friction.

If your window or door is sagging in summer and you are unable to get it to close, try using bar soap to lessen the friction. It will shrink and may help temporarily solve the issue. This solution may need to be repeated frequently during times of high moisture.

A more permanent fix involves making the door or window frame down to a smooth finish. This can be done by hand or using the power tool. A professional can also sand and paint, or stain your frame or door to make it look brand new and fresh.

If sanding and soap aren't helping it's likely that your problem stems from foundation settlement or a damaged crawl space. The first thing to do is check for cracks in the area. If double glazing window repairs spot these indications, you need to call a foundation repair specialist. Foundation damage can lead to uneven floors and a misaligned interior wall and, in turn, sticking doors and windows. It's important to tackle these issues as early as you can to avoid costly and dangerous repairs in the future. If ignored these issues can escalate to the point where your entire home is structurally unstable.

Cracking/Blowing Issues

When double glazing begins to wear down, it could cause cracks to appear. This could be a disconcerting sight and also allow the heat inside your home to escape. It also poses a safety risk for your family members, as the glass's sharp edges could injure them in the event that they break. It is recommended to fix any double glazing windows that have cracks before they get worse, as this may increase the cost of replacing the windows.

Window seals are crucial to prevent drafts from entering the home and keep air between your window panes. Over time, these seals may shrink or even become perished due to changes in weather. Unchecked, it can result in condensation, moisture and draughts within your home.

This issue can usually be solved by a professional. They can repair the window seal to restore your windows to their original state of repair. They may also suggest additional features that will decrease the possibility of a stress fracture occurring in the future, such as trickle vents to improve ventilation.

You can also lubricate the hinges and handles of your doors and windows. This will allow them move more smoothly and allow the lock to perform as it was intended. Apply lubricating oil to a clean cloth and rub it into the hinges and handle mechanism as well as places where they pass through the frame (for example, for windows with sash). It can also be helpful to remove handles from their frames and wash them with warm water to rid them of any dirt or grit which has become stuck to them.

It is crucial to contact a professional if your uPVC doors and windows aren't working as they should. They will be able to find the issue quickly and then resolve it within a short amount of time. It's a lot safer and more affordable than attempting to fix it yourself and possibly damaging the mechanisms. You'll also be able to rest in peace of mind knowing that your home is secure and safe.
