Genuinely Impressed with standard of work

I can’t express how genuinely impressed I am with this company. Firstly the my fitted my parents Bi folds and the work was spot on. We asked them for something special for a door and entrance to our home and we got that in abundance. They turned up when they said they would to quote. They emailed when they said they would and even turned up early to start the install. Have your ever heard that one before craftsmen turn up on time! They also cleaned up after themselves and they genuinely worked their socks off. Very impressed with our entrance and cannot snag anything - it’s just got the wow factor . Perfect job thank you to everyone at JC windows - you are the best.

Patio doors
From start to finish this company was excellent. Mark and Martin turned up at the agreed time and carried out the removal of the 50 year old existing patio doors in a careful and efficient manner. They fitted the new doors to a very high standard always checking we were happy with the work. They cleaned up after there work leaving the site spotless. We have no hesitation in recommending this company. Martin and Mark are a great asset to the company with there attention to detail.

First job was in 2020, and they were superb. Second job,Johns team were great. Unfortunately the builders they used were a complete nightmare. Third job was signed and ready to go, and I was happy to wait 2 months for a builder as I didn't want the last ones back. I had completely stripped out most of my kitchen to facilitate for the build and then having chased them up for days, the builder said he couldn't do it. I now live in a bomb site thanks to these charlatans especially Mark!! Disgusting

The trader replied (on 14/07/2025)
The last communication you had with the office was to cancel due to insufficient funds and no contract was signed for by yourself. Our protocol is to make sure every detail is itemised so the client and our team know exactly what will be the finished works. Unfortunately you regularly change what it is you want us to do for you late at night with our sales team and not the office. Our aim is to deliver a professional completion for both customer and JC Windows, if we feel this isn’t the case we will not start any contract.
Fantastic!

Spot on from start to finish! Upvc sash windows fitted to 2 bays and 3 singles. Mark and Martin ("The A Team") are a joy! Clearly happy in their work, extremely hard working, and their attention to detail is second to none. A perfect job done! I wouldn't hesitate to use JC Windows again. Highly recommended.

First time I’ve used JC Windows This was through a recommendation. I am very pleased with the conservatory. The installation team were fantastic including the subcontractor (plastering), and the service from John and his team. No hard sales pitch and a very good price. All polite, courteous and extremely tidy. I definitely will use them again in the future and only wish I had done so in the past.

I have just had a porch built by JC Windows. I hadn't used this company before but they came highly recommended and I can see why. Everything went smoothly from start to finish. Everybody I dealt with was friendly and efficient. Best of all I love my new porch. Will most definitely be using this company again for further jobs.

Company very easy to deal with. Easy to contact and quick to respond. Had double glazing replaced in lounge windows set in hardwood frame. The survey beforehand was very helpful and the work was carried out with no inconvenience to us, no mess at all during or after completion. Would definitely recommend this company.
