While quality wood windows tend to be more expensive and require more maintenance than PVC windows, they may be worth considering for your home due to their longer life expectancy.

Do Manufacturers sell directly ?

What is the Lifespan of uPVC Windows in the UK ?

uPVC windows are the most durable window material. New uPVC windows bought in the UK usually come with a 10-year warranty, but have a longer life expectancy, averaging 10 to 35 years. 

Can uPVC windows be repaired?
