    We have just had a number of windows and doors installed by Crystal Windows. We chose them after seeing their work on Facebook and their customer reviews; … read more we can now add our names to these glowing reviews. From the very first contact with the company and John, we were impressed by their professionalism and attention to detail. The team that carried out the work (led by Ryan) were a joy to be around and always left us with a tidy house. The product is fantastic and, because we had old persianas removed, the finishing around the windows was excellent.
    We have had replacement windows in the UK in previous houses, but this experience was by far the best, and we would not hesitate to recommend them to our friends.

I can 100 per cent recommend Crystal Windows.
