Testimonials
Crystal Windows recently installed/fitted and had a few minor teething problems. I spoke to customer services who I must say were very fast at dealing with the issues/points I had raised and acted on things immediately. I would without a doubt recommend Crystal to others without hesitation.
Nikolas Keegan - RomfordRated us: 4 out of 5
We chose Crystal Windows because we had used them before in our previous house. We had exactly the same professionalism this time as the last. Very fast yet precise. The windows are of a very high standard. Would fully recommend them.
