``Hi John,
You asked for some comment on the glass curtains you fitted:
This is the best investment in the villa we have ever made. It has transformed how we use it particularly in winter. We have a new ‘whole year round’ living space.

Doris und Hans Pietsch Happy client | 25th January 2021
``Thank you so much, Crystal Windows for the superb security of your Doors and windows.
We are so grateful for our patio doors and Windows security preventing burglars gaining access to our Spanish home. There had been a number of local break-ins and the burglars tried forcing our patio door and windows in three different places and could not gain access.
I want everyone to know the quality of Crystal Windows products prevented my wife and I suffering breaking. We understand the burglars moved to other villas locally and gained entry in those homes without such a good level of security.
Even more impressive was that Crystal Windows attended the next day to repair the damage caused and secure our home fully again.
Absolute peace of mind
Thank you so much ``

Peter Walsh Happy client | 16th July 2020
Could you please pass on my thanks to John regarding the installation of windows at our Villa. The product is of a very high standard, the teams were professional and worked hard against the timescales for our short visit to Spain. Callum and Ryan were both fine ambassadors for Crystal windows. I would have no hesitation in recommending Crystal to other perspective purchasers of double glazing.``

Mr.and Mrs. Wijnands, Costa Blanca Happy client
``I had meant to get in touch to say how happy we are with the new windows.
We were very impressed with the process from sales right through to installation. Everyone was professional, we were always kept informed and it’s a great job.``
Steve Wright, Costa Blanca Happy client
``We used Crystal Windows Spain to replace the original windows in our property on the Costa Blanca because, several years ago, they had replaced our original Spanish wooden door with one which allowed light to penetrate the winter darkness. At that time they went over and above just replacing the door and improved the whole appearance of the entrance. Their technicians replacing our windows showed just as much care and attention to detail as those who had replaced the door. We would have no hesitation in recommending Crystal Windows Spain.``
Yvonne and David Keir, Tuelada Happy client
``Hi Robin - just a note of appreciation for the excellent job you did in replacing all our mosquito nets - right from the start when the measurements were being taken it was clear that your company was very professional and this was exhibited all the way through the entire job which was completed in a timely manner and to a very high standard.
I can recommend your company to anyone.
Thanks again,``
Mike Renucci, Lliber Happy client
'Now that the final work as been completed on our new glass curtains my wife and I would like to express our gratitude for a job well done.
From the meticulous attention to detail of the design process through to the professionalism and cleanliness (and above all politeness) of the installers the whole process from start to finish has gone smoothly like clockwork.
As for the finished product we couldn't be more please. Far more than we ever hoped for, the glass curtains have transformed our home and look absolutely wonderful!
Thank you so much.``

Maureen Barrett Happy client
'The glass curtains from Crystal Windows transformed a windy curved naya into a year round useable room.
At first the family were doubtful as they thought the area would feel closed in and the view would be spoilt, but they have now completely changed their minds. The glass curtains are versatile and easy to slide, arranging them from fully open or closed and any combinations in between, so the view can be enjoyed whatever the weather.
We chose Crystal because of product quality and the slimline frame design. They also installed glass balustrade on the pool deck, two french doors and a single entrance door. Their engineers were punctual, had good knowledge and experience of the product and worked tidily.
A good professional company that we highly recommend.
Penny and Ev. Happy client
'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.
Ruth Ferenczy Happy client
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.
Joachim Hartz Happy client
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.
Alison Pate Tormos
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.

Nigel Merchant New Conservatory
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.
Christopher Replacement Windows
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.
Horst Daverkausen
Many thanks. Very happy with our door. A very big thank you to the 2 fitters. Excellent job.
