We used John several years ago, (moved away, decided to come back). The D/G was old and no window that would open incase of a fire (bungalow). The A Team arrived 0800Hrs thur morning. They had to sort out a few problems removing the old bay window. On fri they completed all the other work replacing the windows in the conservtory and replacing a door lock. All work left clean and tidy and always polite. When it comes double glazing I would have no problem in recommending J C Windows

2nd job by JC Windows

Just had whole house front and side replaced by JC Windows (door, windows, soffits, gutters, dry verges). This is the second job they have done for us - they did the back including a lightweight roof on the previously uninhabitable orangerie. On both occasions they have done a great job - Martin and Mark (did both jobs 6 years apart) are professional and really friendly and the quality of work is exceptional. I would highly recommend JC Windows to friends and family. All aspects - quoting (honest, clear, fair) to completion have been a pleasant experience.

Had JC Windows fit two sliding patio doors to the rear of our house. From initial contact to final installation, the job was perfect. The fitters were punctual, polite and respected our property. Would definitely recommend.

JC Windows fitted my bi-fold doors, a canopy and a front door. Mark came to provide advice, assess and work out a quote. He was knowledgeable and helpful and provided sound advice. The quote arrived within a day or two, with a full breakdown. No deposit was required. John did the technical survey and provided another opportunity for me to double check some things and to seek further information. Both John & Mark were very professional and patient. Martin & Mark the fitting team were excellent. Very tidy, very skilled leaving a high quality finish. Both were very friendly and didn't seem to mind me asking them about progress. JC Windows have been very easy to contact each communication has been friendly and straightforward whether over the phone or by email. . Everyone i have dealt with has been a credit to the company.

I had 8 condensed windows; different sizes, different glass, upper and lower levels. From start to finish, this company has exhibited absolute professionalism. One employee, Mark came to assess and give a quote; which i found to be a fair and competitive price. He was informative and friendly. His visit was followed promptly with a well- presented quote; giving me a breakdown. No pressure was put on me and no deposit was required. John came to do the technical survey and I was very confident that the work would be completed with absolute professionalism and integrity; which it was. Today, the windows were changed efficiently and withno fuss. It has been very easy to contact John and Mark and every communication has been friendly and straightforward.

Moved to a new property without realising the windows needed replacing. Decided to go with JC Windows as Mark was the friendliest and most helpful of the reps we spoke to. They were also the only company that would do the windows the way we wanted. We weren’t looking forward to the actual work being carried out, as the thought of having the house disrupted and there being strangers in your home is never nice. Turns out Mark and Martin were 2 of the nicest workmen I’ve ever encountered. They cracked on with the work from the moment they arrived and left each room tidier than it had been before. The windows were fitted with care and attention to detail and they have improved the noise insulation, security and warmth of the house. Thanks again to John, both Mark’s and Martin for improving our home.

JC Windows did a fantastic job replacing all my windows and doors. Throughout they attended as scheduled and their thorough quote was adhered to, with clear and helpful advice on what was required. Compared to other larger local companies their price was significantly lower, with a high quality product and no pressured sales techniques. The fitters were experienced, professional and friendly. Their knowledge ensured the most difficult of windows were fitted correctly and with care. JC Windows are FENSA registered which provides essential reassurance and documentation for the future. I would highly recommend this excellent local company.
