'The guys arrived on time and completed the work in under nine hours causing very little disturbance or disruption. They were both efficient, very pleasant and polite and cleared up after the work was completed. All in all after my experience I would highly recommend your company.

We are over the moon with the product and would like to thank you for an excellent design & manufactured set of doors and complement the fitters for the absolutely perfect installation and very impressive cleanness of the work and clean-up after. We are very impressed and already recommended CW to friends & family.
Mark & Julie Przeczek Happy client
We have just had glass curtains installed from Crystal Windows and we are absolutely over the moon. Fantastic service from Crystal Windows from the beginning when they came to measure up. John Clements was very accommodating and explained all options that were available to us. The curtains were installed in the time that was originally specified and to a very high standard. We can now use our terrace during the winter as well as the summer – it has given us another room with beautiful views. Very very pleased customers.
Jan Lipscombe Happy client
We would like to thank you for the fine service with the purchase and installation of our sliding doors.
We are very happy with the delivered quality. Also the way you handled the glass break in one of the doors, that emerged after a year and which you replaced under full warranty, earned praise. We have recommended you to our friends.
Jan van der Linden Happy client

Hello John, Our house is like new. All the windows and doors are installed. Thank you for the perfect job. This all started in the first interview with Janina. She explained very well the advantages of your products and she also translated very well the technical things. Your technician Mike gave us an excellent consultation and we felt that he only wanted what was the best for us. You can be very proud of your sons two Ryan and Mark. Ryan was responsible and had perfect control about everything. The same goes for Marc, who worked perfectly as well. Also pleasant was the work that John did, and with him you have a very good colleague. Also because I worked in the construction industry, I know what I am speaking about.
Once again, my wife and I are very happy with the completion of the work carried out. I wish you and your family the best and may your order books for your company always be full.

Hi John, just a quick note to say that over several years now we have had an excellent service from initial visit to installation. Great products and professional work.
Indeed the glass curtains supplied have provided a year round space that is highly recommended!
John Taylor Happy client
Crystal Windows has literally changed the way we live! With their help, we've turned the garage into an office and put in massive arched windows and doors. We're thrilled with it. There was a bit of building work to do, but the whole team were fantastic. They went far beyond my expectations and I would thoroughly recommend them.

Just quick note to say what a good job your installation team did yesterday
They are an asset to your company. Secondly we have been unable to copy any of the new door keys - we have been to all the local locksmiths and all have said the key is a new style in
We need another 8 keys to cover our family - cleaners and rentals. I am more than happy to pay for them if you could arrange via your manufacturers. Once again many thanks for an excellent job.

Hello, We have just transferred the completion payment. Thanks to all at Crystal and particularly to Ryan for making the whole experience so easy. And, unbelievably neat and tidy. We’ll be in touch about the handle, mozzie screen and code lock nearer to Christmas for when we’re back for a few days in early January. I know about the New Year break so it may be mid February before our diaries match.

Hello Anja, Hello Janina, the work is done. We enjoy the result. The transfer takes place immediately. Thanks again for the always friendly accompaniment of this order. We would like to congratulate you on your work team: competent, thorough and friendly. We think about more minor work and will contact you before we arrive.
