I don't usually do this but I was very disappointed with this company. I needed a quote for two smaller windows. After measuring up I was then led through the process of since I was retired I'd get 40% off. The quote came to £3,166 which I thought was astronomical. That was with the 40% off. I was told they needed to use scaffolding which pushed the price up. After much tooing and frooing the quote came down to £2,600. I said I would think about it as I had others coming for quotes. Finally had it all done for £1,200 & no scaffolding was needed. They were installed from the inside. Your windows might be top quality but the sales pitch is hard.
