First impressions were very favourable when we approached this company to build a Conservatory extension. The survey was carried out by Mark in a very friendly and professional manner. He freely gave useful advice and inspired confidence by explaining the steps, creating a graphic design and offering a history of the company and long-term staff. The company have a great relationship with the builders from T-Build. There was good communication and they were always concerned that we were happy with the progression of the build. All in all we were provided with a bespoke service by a professional, polite and courteous team. They excel themselves with their competence, attention to detail, helpfulness and a sense of care. The site was left clean and tidy with all rubbish removed. All work was carried out to the agreed schedule and budget and we have to thank John, the owner, for his great organisational skills in getting the project completed. We would most definitely use the company again and recommend to any others. Thank you

Excellent work by a great team. From the first meeting with Mark (sales) to John (boss) to the work team everything went smoothly. The guys who worked on changing our conservatory roof to a solid/lantern roof did a great job, were very polite and cleaned up behind themselves regularly- never leaving any mess. Two guys came to finish the inside by plastering. They worked hard for a full day, were polite and cleaned up at the end, leaving no mess whatsoever. We also had two new bedroom windows and a front door. Can we recommend JC? Yes. Yes. Yes.

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.

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.

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.
