It is an amazing fact that uPVC double glazing was sold by the industry as a maintenance free product. While it is true the uPVC frame will last approximately 10,000 years before degrading, the mild steal and cast Zink moving hardware parts will last an average of 10 years before they start to fail.
The problem with window company guarantees:
i) Many window companies have gone out of business leaving the guarantees worthless,
ii) Most guarantees last about 10 years so end just when you need them,
iii) The guarantee in most cases only covers the hardware for 12 months and the uPVC for 10 years.
I have known people who already have uPVC windows and doors getting them replaced with uPVC again at a cost of thousands of pounds (not to mention the cost to the environment) because the hardware is starting to fail. This is like scrapping your car because it needs new spark plugs and a couple of new tyres.
Why do people do this?
The answer is simple.
The home owner calls out uPVC window and door installers who only want to install a new window or door and will convince them it is un-repairable. Even if they wanted to repair it they wouldn’t know where to get the parts. You see window companies for instance will use 2 or 3 different types of locks on their doors while there are at least 140 different types.
What the home owner needs is a place where they can buy the spare hardware parts(locks, hinges and handles) so that they can maintain and repair their uPVC windows and doors.
