Highly recommended
Customer Service
We have just had 10 new windows and the roofline replaced. From the initial survey and quote until completion of the work the communication from John and Mike was excellent. The two fitters, Martin and Mark, were brilliant. No fuss, hard working, tidy, and friendly. The standard of work carried out exceeded our expectations, the finishing touches just enhanced everything. We had no decorating necessary at the end of the job, i don't think that's always the case with many companies. We get great pleasure in looking at our 'renewed' house, and have already had compliments from neighbours. I highly commend this company to anyone, and thank them for work.

Excellent work
We have had windows fitted in our previous houses but J C Windows are on another level. The fitters were superb, their workmanship was on a far higher grade than the previous firms. We now understand why JC Windows are recommended by Which.

Another Great Job
Customer Service
John did such a good job on our four bay windows a decade ago that I had no hesitation in asking him to quote for four new windows and a back door this year. Two of our bay windows had been badly fitted by another company and caused some structural damage. John's extensive experience as a joiner and fitter meant that he was able to recognise the problem straightaway and get the job done properly. This time one of John's fitting teams did the work and I was equally happy with the high standard of workmanship. The men worked for two days without even a break for lunch and rose to every challenge which included fitting two windows on a second floor without scaffolding. A scaffolding tower was used for the window on the first floor. I can now enjoy a new back door with more light and no draughts and have already recommended JC to someone else looking for a company which offers quality and good value.

We are ‘over the moon’ that we found JC WINDOWS. Having dealt with some companies in the past who had turned out to be a huge disappointment I really didn’t know what to expect. I need not have worried. John and Mike who we dealt with were absolutely first class from start to finish. I rang for a quotation for 2 bay windows, plus three additional windows. I received a call back almost immediately. An appointment was made for measurements to be taken and they arrived exactly when they said they would. It’s such a refreshing change to have such a reliable company to deal with and such friendly and professional staff. The materials used for the windows is extremely high quality, and the workmanship is outstanding! Also, inside we expected to have to decorate were the old windows were removed, not at all, not one piece of wallpaper was destroyed they have left the inside in perfect condition and were so clean and tidy. I would not hesitate in recommending JC WINDOWS, they were a joy to deal with and their prices extremely reasonable. If I could give them a 10 star rating I would!!

We had 8 windows and patio doors fitted to our property. A+++ service fantastic from start to finish. Gary and Steve the fitters were just brilliant and did a fabulous job. I would have no hesitation in recommending this company and would use them again in a flash.

Excellent service & workmanship.
Customer Service
I needed 4 Windows replacing and a new Back Door, so I first contacted a Company that sends a "Newspaper" through your Door and arranged a Visit. Sadly, it was a Salesman with all the baggage that comes with it... Overpriced and Pressure Sell and he kept coming down in Price to get the Deal... I wasn't having it. So after briefly looking online I found JC WIndows who promptly came out and gave me a quote and I decided to go with them. The 2 Installers came early and didn't stop throughout the whole time they were here. They offered advice and explained very clearly the options I had when the odd minor obstacle was needed to be overcome. Even with just the Windows, before the Back Door was fitted, I noticed the difference in Heat retention and the reduction in noise from outside and with the Back Door added, this was further improved. My only regret was not having them replace all my other Windows and Front Door, but when I do, I won't hesitate to get JC Windows back to do the work. In one word...Quality.

Great work all the way!
Customer Service
Really pleased with the whole process of having our windows and front door replaced. From the initial contact, the visit leading to a quote and the installation, the service was perfect. Nothing was too much trouble and all work was completed tidily without any cause for concern. Martin and Mark worked non stop to improve our home and just needed coffee and the occasional sandwich to keep them going. Wouldn't hesitate to employ your company again!

Full replacement crumbling 1930's leaded lights with triple glazed powder coated aluminium tilt and turn.
Customer Service
In every respect; from customer service to quality of installation J C Windows surpassed expectations. The completed installation is a joy. The look and feel of the house is immeasurably improved. Everyone should include John and his team on their shortlist of installers and if chosen will provide a first class service.

Excellent work and customer service once again.
Customer Service
We previously had all house windows replaced and conservatory refurbished by JC Windows, so on this occasion we had no hesitation in asking them to replace our garage door and window. Once again excellent work and customer service.
