What our customers say
From beginning to completion customer care excellent, the fitters (Bob& Tony) were brilliant explained all what was going to happen during time they were here, tidy, courtias and a professional job. Well done
Right from the start Crystal Windows were great to deal with. Friendly, efficient and professional. The person who came to give us a quote was great, explaining the products, installation process and pricing very clearly. It only took a week from the quote to installation. The windows are a high quality product, as is the cladding we had done on our garden shed. All work was done to a high standard and the workers were courteous and cleaned up after the work. Communication and punctuality was great at all times. Highly recommend this company!
Great service from Crystal. Very charming people from the Sales team to the installers. Thanks to Darren and Luke for doing a great job and ensuring everything was done and met my expectations. I would recommend Crystal over other providers. Honest people, great price and an excellent job done.
