Frequently Asked Questions
In the glass and glazing business, there are a few questions that we get asked all of the time.
Hopefully, we will be able to answer these common problems here on the site. This way you will get a bit of a better idea and know exactly what’s wrong, and then how it can be dealt with.
Total replacement is not always necessary, most of the time we will be able to repair part of a window unit, the hinge or lock, or even just the window putty. With misty glazing where condensation has entered the individual unit, we can replace the affected pane and leave the rest alone.
We will always offer, you the customer, answers and advice so that you can make an informed choice on how to proceed with the replacement or repair.
If you need us, we are only a phone call away on 07872 147 269.
Why won't my uPVC window close
The most common reason for a uPVC window not to close is that there is damage to the hinges or lock. It could be the case of the sash has dropped and just needs replacing.
All of the above are repairable and should take no longer than one hour to fix by a competent window engineer.
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.
Why does my double glazing have condensation in between the panes?
Condensation between window panes occurs when the seal between the panes is broken. This is caused by either the glass breaking/cracking or the life span of the seal expiring. Double glazed units have a life span of approximately 10 Years
Do my windows need to be made of toughened glass?
Any door side panels or any type of window within 300mm of any door must be safety glazed i.e. laminated or toughened. Windows that are within 800mm from the finished floor level must be glazed with safety glass. Any glass balustrade or canopy should also use safety glass.
How long will new uPVC windows last for?
Your new uPVC windows may be guaranteed for 10 years but they usually have a far longer life expectancy. With the correct and professional installation of high-quality uPVC windows and with good maintenance they can easily last up to 20 years.
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.
