"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."

"I can wholeheartedly recommend Crestshield Windows. They installed six uPVC sash windows and a casement window in my flat in Autumn 2025 and were professional, friendly, helpful and informative from start to finish. They managed to meet the rather precise timescale that I asked for, which was a great help. 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 is a pleasure to look at from inside and outside."
