We had this company recommended to us they were also Which recommended and they are a local family firm. From getting our first quote to the installment of our door and windows we received courteous and helpful service. We were very pleased with the final look and quality of the product. The fitters were very good at their work and they have been with the company a long time always a good sign. They always tidied up as they went along and we are very happy with the results

Contacted John at JC Windows to provide a quote for secondary glazing in our front room and upstairs bedroom. Happy with the quote and arranged an installation date. Martin arrived on time to install the secondary glazing and what an amazing difference it has made. We live on a busy main road and for the first time in 20 years of living here the noise from traffic has been greatly reduced. Martin was friendly, professional and left the house clean and tidy and I thoroughly recommend this Company.

We are deeply saddened that you are unhappy with the Kitemarks on your toughened glass, these are not a decoration but a necessity by law, they cannot be hidden out of sight. We have to abide by rules and regulations set by Glass and Glazing Federation. The Kitemarks are a statutory requirement to be positioned in a corner of the glass with adequate visibility. All glazing companies have the same standard throughout the U.K. Please contact the office for any assistance you require.

The survey was carried out at the agreed time and in a professional, friendly manner. Useful advice regarding the type of glass was also given freely. The two fitters who installed the roof were obviously competent and completed the job with no problems. They were also very helpful and wanted to be sure that we were happy with the finished article. The site was left tidy, with all rubbish removed. I would certainly recommend this company and will use them again for any future work.

Overall I was very pleased with this company. They came to survey the job at the time they arranged. The estimated time for the work to commence and be completed was accurate. The estimated cost was entirely correct. The men who did the job were very hard working and they did an excellent job. I am happy to recommend this company.

John visited me on request as I needed a new roof on an existing conservatory. John advised me when needed and arranged to have a new roof a new patio door and two badly needed windows. The guys that carried out the work, were great guys, very hardworking (not even had a lunch break) very polite and clean workers, I am more than pleased with the result and would recommend this company, The guys cleaned up after themselves leaving no mess. The work was carried out and completed on the time given.

JC Windows built a small orangery for us. John who is the owner kept an eye on the work every step of the way. He is always on the end of a phone if you need him. He helped advise us on what would look good based on his expertise. He uses quality tradesmen who are polite and get on with the work. The work was completed in a timely manner considering the bad weather we have had and we are thrilled with the new room. The work came in bang on budget with no hidden extras. I would not hesitate to recommend J C Windows.

We have had all the windows in our house replaced by JC Windows - eleven in total. The work was done with a high degree of professionalism and skill by the “A Team”, aka Martin and Mark. They arrived promptly each morning and worked hard the whole of every working day, not even pausing for their coffee breaks, nor did they stop for lunches. At the end of each working day, the site was left immaculately tidy and in addition, each room they worked in was scrupulously cleaned. Pleasant and cheerful, they kept us apprised of their progress throughout. It was a privilege to have such excellent workers doing our job. Thanks too to John and Chris for their help and advice in the planning stage.

Shopped around, researching many manufactures/installers before selecting JC Windows, from the initial contact, through to installing the last pane of Glass, the service was first rate. The job carried a degree of difficulty but the installation team handled it with complete professionalism, at every stage we felt like we were in safe hands. Many thanks to all at JC

The two tradesmen who installed our new triple glazed windows were friendly, courteous and very obliging. On arrival they protected our carpets and got straight on with the work. When each room was complete they left it clean and tidy behind them. The job was completed within the planned time schedule and given the way everyone at JC Windows conducted themselves from start to finish, we have absolutely no hesitation in recommending this company.

JC Windows have just replaced all of our windows and exceeded all of our expectations. From the initial contact with Mark (salesman) to the visit from John the owner to discuss the finer points and the excellent fitting team of Martin and Mark, we have experienced a trouble free process. A special thanks to the fitting team of Martin and Mark whose professional approach to producing a quality job is much appreciated and carried out the work even during some inclement weather.

This is the fourth time we have used JC Windows and, as usual, we are extremely happy with the work. We had new patio doors and windows, a new window in the utility room and a new back door fitted. We also asked for the doorway to be widened, which the installers did to our requirements. The installers were professional, knowledgable and skillful. They completed the work on time despite terrible weather and conditions. I highly recommend this company.

I contacted JC windows in order to get a conservatory built onto the rear of my property. I asked for slanted disabled doors as I have a son who is wheelchair bound and a disabled daughter this was agreed upon consultation and paid for in full!!! however this was not completed and after contacting JC windows they informed me that they were not able to do so as the garden slabs were too high and if I wanted this to be done I would have to order and pay for another door, even though my requirements were discussed during the consultation. The floor base was not made level and upon contacting JC windows AGAIN this still hasn’t been rectified and there is a gap between the floor and the base of the wall, the staff that completed the base of the conservatory would come for 2 hours (if that) and then disappear without notifying us! John was extremely rude in his mannerisms and the way in which he spoke to us! We have since contacted JC windows yet again as a crack has appeared on the ceiling and we were asked to send photos over, to which we did however as usual there has been no contact from the company regarding this! Extremely poor customer service and even worse workmen-ship. I paid £26,000 for this conservatory for my wishes not to be followed and for bad work with extremely rude and unhelpful service! I do not recommend this company to anyone

Dear Mrs B when we ordered and discussed the conservatory, we wasn't made aware of your intentions regarding the landscaping of your garden which was done after the build work had been done, unfortunately your landscaper has installed the paving sloping back to the conservatory which is very odd as usually the ground would slope away from the new dwelling allowing water to flow away from your house not towards it. we offered to lower the doors but you would have to slope your paving away from the conservatory allowing the doors to open at 90%. we have tried to contact you regarding the hair line crack in the plastering, this can some times happen if the plaster dries to fast, please contact us through email or ring the office and we will call out at an arrange time to suit your self.

JC Windows- Nightmare

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.

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.

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.
