  Brilliant

  Posted 4 days ago

  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.

  High quality installation of double glazing

  Posted 18 November

  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.

  High Standard of Trust and Excellence

  Posted 25 October

  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!

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.

  New bedroom window and front door

  Posted 04 June

  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.
