Great service from Steve from start to finish, helpful advice and hassle free ordering. The installation of the bifold doors and windows by Dennis and Robbie was very efficient and tidy. I’m very happy I chose to use Cristal Windows and would recommend them to anyone.
I had the roof of the conservatory completely replaced in March 2025 and was very satisfied with the standard of service and the quality of the building work at the time and was happy to provide a review then. After more than a year I can confirm that the replacement structure has performed well as have the new doors that I had installed into the garden. I would use the services Cristal Windows again and am also pleased to recommend the business.
From start to finish the information and communications from Steve were excellent. The Rehau products chosen and supplied are of a premium range of windows and doors that we are extremely happy with. Dennis and son Robbie fitted them with an attention to detail that is unfortunately, not always found nowadays and cleaned up afterwards on a daily basis. We have no hesitation in recommending this company and their workmanship to anyone considering this kind of home improvement.
I had all my windows and doors replaced by Steve and his team. From the initial contact right the way through to completion the communication was spot on. Dennis and Robbie who did the installation were very friendly and worked efficiently keeping the place clean and tidy as they worked. I did encounter a problem with one of the products but it was dealt with quickly and professionally.
After much research we chose Cristal to replace some of our windows. I found them very easy to work with right from the start. They were very accommodating when I made some slight changes to the requirements and came up with a very competitive quote which was not accompanied with the “hard sell” attempts I got from some other companies. The installation was completed smoothly by Dennis who left everything clean and tidy at the end.
We’ve had Cristal Windows carry out several installations over the years and have been really pleased with both the service and the quality of workmanship throughout. They first fitted new soffits and fascias in September 2020. This was followed by new front windows and a front door installed in September 2023, and finally all rear windows and a back door fitted in February 2024. The workmanship on every job has been excellent.
I have used Steve and the team from Cristal Windows on 3 separate occasions across 3 properties. I used Steve every time because he delivers a quality product, in a professional way at a great price. I can definitely recommend them.
We chose Cristal Windows to replace our conservatory roof and install a new front door. Steve was prompt to measure the site and provide a competitive quote. Dennis and Robbie carried out the work (sometimes in bad weather conditions) and at all times were friendly and professional. The work was carried out to a very high standard and the site was left tidy at the end of each day. I cannot recommend the service and work carried out highly enough.
When we decided to replace our existing windows and doors, we chose Cristal because of the excellent reviews we found on this site. We were not disappointed. From our very first phone call enquiry we experienced prompt, friendly, knowledgeable and efficient service. Steve came to us, gave us lots of helpful advice and showed us examples of the most suitable installation for our particular requirements.
We recently had a new front door and side panel installed. This is the third time we have used this company, having previously had our house windows replaced and a new conservatory built. We highly recommend Steve, Dennis and Robbie for their professionalism, high standard of workmanship and attention to detail. Any issues that arise after installation are always dealt with promptly and efficiently.
