Great work
Customer Service
We contacted JC Windows after our windows started leaking, John came out to have a look the next day and advised what he believed to be the problem. We had x2 large bay windows fitted, and for aesthetic purposes, we decided to get the medium-sized single-window changed on the front of the house also. It was all done very efficiently and tidily, I was most impressed by the lads fitting the windows as we have recently had the house re-rendered and they didn’t leave a mark; no mess on it, no damage to the rendering, it’s a smashing job. So far Johns advice was spot on and no leaking whilst the rain has been heavy and the windows look great. We recommend John and the lads, and not to mention great value for money with the work you receive.

Quality professional installation
Customer Service
We chose JC windows for their attention to detail and professionalism. They certainly deserve their place as a Which? Trusted Trader. We got a detailed quote of the work which was taking place which was a new window installation. The job was done to a outstanding standard using quality materials. They were very polite,friendly and helpful too. We would not hesitate to recommend them.

First class company.
Customer Service
The final installation of remaining windows of Dining room completes the whole house. Everything from initial consultation through installation was everything you hope for. To say I'm delighted seems insufficient praise. The house is transformed.

Excellent and professional survey

The work was carried out during lockdown. Two fitters came and installed the window and left having completed the task also taking their debris with them

As a subscriber to which magazine when we required new bay windows upstairs and downstairs we looked on the which magazine Site And we chose JC Windows to do the work. The job did not go smoothly. Some of the windows were manufactured the wrong size and we spent two days with a boarded up the bedroom window. On completion we were not satisfied with the workmanship and complained to the owner of the firm who visited and agreed it was poor. Arrangements were made to come and put the work right but the fitters made excuses and it was never completed we decided not to have anything else to do with the firm.This morning I woke To find a 5 foot piece of my upstairs window lying on top of my car,the section appeared to be extremely warped. I have photographic proof of all details mentioned here. We have contacted the company to repair the window under the warranty and I will review these comments after they have come to the property and put the job right.However They were not the cheapest and I would certainly not recommend them to anyone.

Dear Mr & Mrs latham I'm really sorry to view a bad review regarding work we installed for you last year, unfortunately the double glazing for your bay windows was damaged (broke) in a vehicle accident and no replacement was available in such short notice, hence we had to temporarily board up, We glazed the bay window within a couple of days with the correct toughened safety glass which normally takes 6 working days to manufacture. we responded to the trim that had come adrift from the window at your earliest convenience.
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.

Thank you from all at JC Windows
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!!
