I received terrible customer service when enquiring about the condition of my white wood grain door which is 6 year old. The door has become yellow and I enquired whether this could be resprayed. I was never inform these doors would lose there colour, if I knew this I would have bought a coloured door. I was rudely told to just wash my door which I had already done. The gentleman I spoke to was rude and dismissive. I have since sent a letter to the chief executive and it's has now been one month with no response. I am very disappointed with the customer service I received.

I have just had my conservatory refurbished by Global Windows, they replaced the whole structure above the dwarf wall, including installing a new glass roof. They also did the electrics, flooring and plastering. Throughout the process Billy and team have been brilliant. Everything ran according to schedule and everyone we encountered were friendly and professional. There were a few issues along the way caused by issues with the original structure (nothing to do with Globals work) and they were dealt with quickly, effectively and without quibble.

The new glass roof has made a big difference too, I was sceptical but it actually does work to retain heat on cold days and it blocks the sun on hot days. I can't recommend them highly enough, great company.
