FAQ’s

Why do my windows get condensation on the inside?

Condensation on the inside of a window is caused by excessive moisture in the house. This occurs mainly in the winter when the warm air inside the house condenses on the cold windows. Double glazing can reduce this problem.

How long does it take to replace a double glazed unit?

Depending on the glazing system and size of the pane, a standard uPVC or aluminium window would take around 20-40 minutes to replace correctly. A timber-framed window may take twice as long to replace.

Is a window survey free or do I need to pay anything?

LN Glazing provides a free glazing/window survey. However, it is quite possible that you could pay up to £50.00 from some companies.

Why are my windows so draughty?

Broken Hinges
The most common reason for draughts coming through your windows are broken window hinges.

Hinges can become stiff and rusty if they are not kept clean and lubricated eventually causing them to break and forcing the window out of alignment. This will prevent the opening part of the window known as the sash from closing correct against the rubber gaskets (window seal) allowing air to travel through the gap between the gasket and the sash.

There are a number of ways to test whether your hinges are working in the correct way.
By simply opening the window and taking a look at the window hinges just to see if you can notice any kinks or bends in the hinges.
The push test by opening and then closing the window, gently push your hand against the top corner (hinge side) of the opening part of the window and then repeat this to the bottom corner. if the window has any movement then this is a sign of damaged hinges.
The flame test (please take extra care if you choose to do this) simply by holding the flame of a lighter close to the window seal. If the flame moves or goes out then this is another sign of hinge damage.

The Solution
You can buy a pair of friction hinges from most window shops they should not cost you any more than £25.00 and replace them yourself. As a top tip always remove the glass from the opening window before removing any screws from the hinges and ask a friend to lend a hand. We would always recommend calling a professional. LN Glazing offers a hinge replacement service starting from £80.00+vat per pair. We always fit plastic hinge protectors as standard give you new hinges a longer life span.

Rubber Gasket
Another reason your windows may be letting in a draft is that the rubber gasket on the window frame has gone flat or cracked.
What is the gasket?
you may be thinking the gasket lines the window frame itself, with one gasket on the sash of the window and another on the outer frame so the open sash window and the out frame need to be push firmly against the gasket to prevent any drafts.

The Solution
This is not a big issue and can be solved quite simply just by replacing the rubber gaskets on the window frame and the opening sash window this is a service that we at LN Glazing provide from Just £40.00 per window
