‘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. Yours sincerely,  Ruth Ferenczy


‘I would like to take this opportunity to say a big thank you to everyone at Crystal windows. The service we have received has been second to none and we are very pleased with the quality of the product.

Unfortunately you were called in to rectify a bad job made by another company which made us wary but I can thankfully say we are no very satisfied. The guys who fitted the windows were two very polite and professional people. Big thanks to them for their patience.


We will defiantly be using Crystal windows again in the future and will certainly recommend you to our friends and neighbors. ‘


Kind regards

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!

And a great thank you to your sons Ryan Glen and Mark who are a great credit to you and your firm. They were very courteous and helpful.

We have replaced all of the windows and doors in our apartment in Alicante, so quite a job and inevitably we were anxious that the end result worked well for us practically but also looked the part externally. As Spanish is not our 1st language we have found it difficult to convey the things that were important to us or have those conversations around what are, after all, technical details that would leave us confident that there would be no surprises at the end, be that functional/appearance or financial.  That unease led us to contact Crystal Windows where we quickly gained the confidence that our requirements had been understood, challenged where necessary and a proper survey undertaken. We were also able to visit the factory and see the products we were buying which was reassuring in itself. The process from contract to installation has been very smooth and we’re delighted with the end result, you sense for them that reputation is everything and that they are motivated to ensure you’re satisfied, we certainly are.

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.

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.

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.

Just a short note to thank you for sorting out the problem with the front door so quickly and efficiently. Ryan immediately identified the problem and sorted it out, and the door is now opening and closing perfectly! We are very pleased with the job now that this has been sorted and would be happy to recommend Crystal Windows to anyone thinking about changing to PVC.

I am writing with regard to your visit this week to attend to my casita door. I would like to thank you for your prompt attention and quick response to my call. My house was fitted with new windows and doors almost 8 years ago and we have been more than satisfied both with the product and the excellent quality of the workmanship and your guarantee of ten years really is valid. This is what I call great after sales service. Wishing you every success in the future.

Hi, Just a quick note to say how pleased we were with the windows and the team who did the work on our villa. It was remiss of me not to do a photo of before and after – but then I am not sure you would spot the difference.

Just a short note to say how pleased we are with our new windows. They have already made a great difference and we are sure the tilt and turn will be a real positive feature in the hot summer months. The screens on the doors are both clever, robust and practical. Many thanks on a job well done!
