He done all the measurements gave me a price good price within a week they where fitting in my porch and can only say its the best thing I've done since lock down I have a smile on my face every time I come down my stairs Work men clean up all these mess. The one good thing is the company's call you to make sure your happy well I'm very happy you can be too.

If the rest of their Installation crews are as professional in the work as the 2 guys I had. Then I would recommend Crystal Windows time and time again. From Start to finish great care was taken in the fitment of our French doors. Constantly measuring and checking everything fitted perfectly. Looking forward for the installation of the rest of my windows. Funds permitting. Well done.

Sam and Paul were our fitters. They were brilliant. Everything was done cleanly. They were always on time, polite and helpful. Everything went smoothly and the windows and doors look amazing.

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.

Great service. Polite prompt. Tidied up after themselves and windows are great quality. So why do I have to haggle over the price? This is so old school and the original price I was given was really expensive . Eventually we got down to a reasonable price admittedly a pretend phone call was made and lots of reply on the calculator. Not happy at all with the sales process and the actual work was great. They should be proud if their product and behave honestly around the pricing

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!
