The locks are not working properly

Many people install anti-burglar devices on their main doors and gates however, they overlook that windows are prime targets for burglars. Incorrect locks could cause drafts to enter the home, allowing valuable heat to escape, and weaken your home's security.

If your uPVC windows locks don't work, it is likely that the mechanism of the lock is blocked. This is typically caused by the gearbox breaking in one component. This could cause the handle to not open, but instead to turn 360 degrees. This is a common problem with uPVC casement windows, but is also present in tilt and turn windows, and even sliding sash windows.

If this happens you can unlock the lock by applying pressure to the lever handle. This will allow you to open the gear box and restore the window's opening. If this doesn't work then you might need to replace the entire mechanism for locking windows.

Most modern uPVC windows use espagnolette locks. These are a locking system inside the window that secures the window using locking cams that resemble mushrooms that are inserted into the frame. The handle is the one that operates the gearbox which then activates the cams, causing them to move upwards or downwards. A common fault with these is when the spindle on the lock is damaged which causes the handle to turn freely but not move the window open or close.

double glazing repairs can also cause your window to appear locked, but isn't actually. This can occur when the rods in the centre, also referred to as crocodile teeth fixings in the gearbox snap off. Misty Glaze will supply and install replacement rods if this happens.

It is important to not try to force a stuck or broken lock. This could cause a lock to snap or break, especially if you have windows made of uPVC which expands and contracts when temperatures change.

Sticky Doors/Window

It's annoying to have windows and doors that are stuck and sag, but they can be a sign of more serious structural problems. It's important to get professional help if you have difficulties closing or opening the door or window. The issue could be the result of various factors such as foundation settlement and inadequate support for crawl spaces.

Doors and windows often get stuck due to humidity or the frame itself. When exposed to moisture, wooden frames can warp. This can make opening and closing them difficult, even if the hardware in good condition. The wood swells when this happens and pushes against the hinges creating friction.

Rub the window or door with soap to lessen friction if it sticks in the summer. This will allow it to shrink and can resolve the issue temporarily. This solution will need to be repeated frequently during periods of high humidity.

Sanding the frame of the door or window to a smooth surface is a more permanent solution. This can be done either by hand or with the power tool. A professional can also sand down and stain or paint your door or window frame to make it appear new again.

If soaping or sanding doesn't aid, the issue could be caused by foundation settlement or a compromised crawlspace. Examine for cracks in your area. If you notice these indications, you need to contact a foundation repair specialist. Foundation damage can lead to uneven floors, misaligned walls and stuck windows and doors. It is important to address these issues as early as possible in order to avoid costly and dangerous repairs in the future. These issues can get worse until your home is unsafe to live in if it is not taken care of. Contact the Southeast's most renowned foundation repair experts today to arrange an inspection and repair!

It is recommended to fix any double-glazing window with a crack before they get worse. This will increase the cost of replacement.

Window seals are essential to prevent drafts from entering your home and keep air between the window panes. As time passes, these seals can shrink or get damaged due to changes in weather. If not checked, it can lead to moisture, condensation, and draughts in your home.

Rub lubricating oils onto a lint-free cloth and rub them into the hinges, handle mechanism and areas where they pass through frames (for instance, a sash window). It is also beneficial to remove the handles from the frames and wash them with warm water to rid them of any dirt or grit which has been sunk into them.

It is essential to speak with a professional if your uPVC windows and doors aren't functioning as they should. They can pinpoint the issue quickly, and repair it in a brief time.
