New installations 

Crestshield Windows Ltd

The team were great - from Sam and Elaine arranging an appointment for Peter to come and assess and survey to then having the new door fitted by Owen.  Amazing customer service!

The care and attention to detail provided by putting customer at ease.

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!

Great service and prompt installation!

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.

All Windows Replaced, Upper Ground Floor Flat

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.

Brilliant

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 quality installation of double glazing

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!
