New Conservatory Roof
Customer Service
Despite the supply chain difficulties that everyone is experiencing at the moment, JC Windows completed the job within 2 weeks. The workers were professional and friendly and cleaned up every evening. We are very pleased with our new conservatory roof and would definitely recommend them.

JC Windows- Nightmare
Customer Service
We invited JC Windows to advise us on the construction of a conservatory/orangery on the rear of a house we had recently moved into and Mark came on 8 April 2021 to carry out a survey and discuss the construction with us. We were assured that they had employees who formed 2 teams so there would be no problem with the supply chain. What we got was something totally different. The tradesmen carrying out work were in fact sub-contractors, not employees and we finished up having to deal with and contact these direct in order to have continuity of the job. As part of the agreement we requested that the level of the floor in the conservatory be made the same as the kitchen as we intended to remove the doors and have the kitchen flow into the conservatory and to have a continuous floor and were assured this would be done. We agreed a price of over £23,000. The ground was cleared and made ready to build but a number of delays arose due to supply problems with concrete for the base. When the bricklayers arrived to commence, they were abusive, rude and kept disappearing from the site. On completion of the work we requested a visit from JC Windows and they agreed to knock down the walls and pillars as the workmanship was of poor quality. We have now found that the original base was not level or the same height as our kitchen. as a result the skirting boards left gaps and we have a slope between the two rooms. We have had this put right ourselves. JC Windows gave little support.

The trader replied (on 09/09/2021)
Dear Mr H We were saddened to read your review and apologise for any inconvenience caused due to the current Brexit and Covid 19 pandemic, this has affected the construction industry on a huge scale and some materials have become scarce or difficult to source with long lead times arising from this; affecting the time spent on site. We apologise profusely for any inconvenience caused and can understand your frustration wholly. We do subcontract all building and plastering work, it would not be cost-effective for any double glazing company to employ their own builders and plasterers, that being said we have worked alongside them for many years. You asked if you could change the colour of your chosen bricks during construction. This wasn’t a problem at all as it was in the very early construction stages, it wasn’t based on the quality of build, it was a personal choice and we agreed that the colour selection could be changed. We hope that you are now entirely satisfied with your new colour selection. We kindly absorbed all costs in materials and labour to make the change. The 5mm variation is standard and allows for under-floor heating and tile adhesive. Once this is completed the flooring will have a fluid continuous flow and will look incredible. Your woodwork should be fitted after a tiled floor. Thank you for your review; once your flooring is complete we would love to arrange for our photographer to visit to shoot the installation for our media content.
Very professional job.
Customer Service
We had a patio door, front door and some cladding fitted. Both fitters were exceptional, very polite, did an excellent job of fitting and lots of attention to detail in finishing off an all-round brilliant fit. Arrived on date given. Price paid was as quoted. Cleared up all the mess, nothing too much trouble. Looks fantastic would highly recommend JC WINDOWS.

JC Windows fitted two windows in our flat. We used them again as we were entirely satisfied with the windows and doors they replaced on our home earlier this year. Once again great service and product and keenly priced.

Happy customers
Customer Service
J C windows have done an excellent job in raising our pitched glass roof to a flat roof and installing a lantern. The original roof, windows and patio doors needed to be removed in order to build higher brick columns to support the new roof as well as change the original window sizes. The job was complex as we needed to retain the original kitchen units and were very concerned about water ingress. Rather than removing the roof John insisted it was put on acro props with visqueen nailed to it to protect the kitchen from rain damage and thank goodness for that decision because we had terrible weather and lots of rain but thankfully our kitchen units were fine. John’s fitters Gaz and Byron have been excellent, nothing has been too much trouble and they even cleaned the windows and plastic as part of the service. Thank you JC windows for an excellent job well done 👏👏👏

Excellent job done
Customer Service
We had all of the front Windows replaced the guys were punctual professional and very knowledgeable we felt easy as soon as they started. When we go on to have the back of our house windows replaced we won't hesitate to go with. JC Windows again and will be recommending them to friends and family.

First Class from start to finish
Customer Service
I found JC Windows in a local advertising booklet dropped through the letterbox. I contacted JC Windows via their website and received an acceptable quote within an hour or so. I agreed on the price and within a week or so John arrived for an on-site meet, talked through the job and agreed on the final project. As agreed, within 6 weeks the door and additional work were completed. The quality of work, door and additional work was first class. The two fitters were very polite, talked through the job with me and were extremely tidy both during and at the conclusion of the job.

Professional service and a quality product
Customer Service
I would highly recommend JC Windows for all your door and/or window needs. From start to finish they provided a competent and professional service. During the initial meeting with Mark he gave us several ideas for both our new front door and a internal one. On the day of the fitting of both products the fitters arrived on time and throughout the day updated me as to where they were up to. At the finish of the job they thoroughly cleaned up and removed all rubbish. The doors we have had fitted have an excellent finish and are exactly what we had ordered. The price was as agreed during our initial consultation. Overall, a professional and efficient service backed up with a great quality product that has improved and enhanced our property.
