Highlights
"The team were fantastic in fitting our door at a competitive rate, great service from the initial meeting from Peter and throughout with the wider team always at hand and responsive and managed to fit us in for a prompt installation. Will definitely be using Crestshield again and recommending; my referral was off of a family member recommendation who had their door fitted a number of years ago. Thanks all!"
"We had a great experience with Crestshield Windows from start to finish. Communication was excellent throughout, and everyone we dealt with from the sales staff to the surveyors and fitters was professional, friendly, and genuinely lovely. The quality of the windows is exceptional, and the pricing was very competitive compared to other quotes we received. We’re extremely happy with the end result and wouldn’t hesitate to recommend Crestshield Windows to others."
"Just had whole house double glazed and external doors replaced. Bradley, Ian and Sammy were polite, friendly and extremely hard working. The windows and doors look great! Really pleased and would highly recommend."

Just had all windows and external doors replaced. Brad, Ian and Sammy were polite, efficient and very hard workers. Windows and doors look great. Would highly recommend.
I can highly recommend Crestshield Windows. They installed six uPVC sash windows and a casement window in my flat in Autumn 2025 and were professional, friendly, and helpful from start to finish. They managed to meet my rather precise timescale request, the windows they supplied are of very good quality and the installer Brad was meticulous in his work, and in his care and respect for me and my home. Both internally and externally the work that Crestshield have done is excellent; it has made a major improvement to the sound and heat insulation in my flat, and it all looks really good, too.

I was convinced I had to purchase a new door until Peter came to take measurements. When I explained the issue, he immediately took the time to investigate, fixed and, to my surprise, he discovered that my door was working perfectly fine. He told me honestly, “You don’t need a new door — it works!” I was genuinely moved and deeply impressed by his honesty and professionalism. Other companies told me I needed a new door, but Peter’s integrity saved me from making an unnecessary and expensive purchase. Thank you Peter!!! I will absolutely recommend your services to everyone I know!
Crestshield Windows Ltd, very friendly staff. We had replacement French door fitted. The team were punctual and polite, cleaned up afterwards, excellent work. I was kept informed all along until the work was complete. Highly recommended, and would not hesitate to use again.
Shout out to Peter! (who did the initial consultation) he worked with me to get the windows I wanted within my budget. The windows look great and the work was done in the time frame planned. Every time I rang in I got such a warm and friendly response from office team(Sam and Elaine). The guys fitting the windows always told me when they would be arriving and cleaned up after themselves (Kieran and Brad). The surveyor did arrive much later than was arranged but it was eventually resolved and he was a lovely chap, who clearly knows his stuff. so I would definitely use their services again.
I couldn’t be more impressed with Crestshield Windows Ltd. From the initial consultation to the final installation, the entire process was seamless and professional. Their team were punctual, courteous, and clearly skilled at their craft. The quality of the materials used is first class, durable, sleek, and built to last. It’s refreshing to see such attention to detail and pride in workmanship. I highly recommend Crestshield Windows to anyone seeking high-quality windows and expert installation. They exceeded all expectations, and my home feels brighter and better. Thank you Ian!
Very good job. Painless experience from quoting to installation. Would use again definitely. Even fixed my front door free of charge.
Very good service. Great products. I highly recommend Crestshield Windows. Having tried three other companies, I chose Crestshield Windows. Not only are they a local company, they're dedicated to doing a good job. During my enquiries, all of my questions were answered, the prices were laid out very simply and a timeline made clear. Throughout the job, communication was incredibly easy, deadlines were met and the work carried out smoothly. A year later, the window and door are still working very well without any issues at all. I'll be choosing Crestshield Windows in the future.
Peter did the initial visit and fully explained the various choices of doors etc. They kept us informed of the progress as the doors were being prepared and the date for installation. Brad and Scott who did the job were punctual, totally professional and did an excellent job. Overall a great experience from beginning to end.
Great work. Good communication, fair price. Would certainly use them again. Thanks
Excellent service. The installation time from when Peter first came to measure up was very quick. The fitters arrived on time and were first class. They cleared all rubbish and installed the window professionally. I would definitely use Crestshield again. I can highly recommend them.
Punctual, friendly and high standard of work done with everything explained as they went along
We have had all our windows in our 4 bedroom house done by crestshield and we are so pleased with the high quality, excellent, professional and clean workmanship. The staff are so friendly, helpful and very knowledgeable with a great price. Thank you guys you are all amazing. 👏 🤩 ❤️
Crestshield came to see me after an attempted break in and arranged for the windows to be replaced as a matter of urgency. They were professional and sensitive at the sane time. Great job done.
A huge thank you to the Crestshield team. The admin, scheduling and payment was really well organised by Samantha and Elaine, who were always available to chat. Peter was brilliant. He came to the flat, made some measurements and detailed the cost, as well as his opinions. The surveyor was just as good, when it came to doing the proper measurements. Really grateful to Brad and Scott who conquered fitting the double glazed windows on a hot day. Crestshield were brilliant from start to finish. Even when I had some project delays, they were flexible. An excellent and trustworthy service.
I researched local companies quite thoroughly and got several quotes. We ended up choosing Crestshield and were not disappointed. The measuring visit, office organisation and fitting were all done with care and any queries we had were addressed swiftly. Billing was clear and there were no unexpected costs. All staff were very friendly and helpful, and the fitters also tidied up well. A good experience, and would definitely use Crestshield again.
