Generation Windows are a fantastic company. Excellent communicators and very good value. They did a wonderful job replacing two windows in all of conversion. They came on time, they were cheerful, they worked in subzero temperatures and had a fabulous job. They cleared up brilliantly after themselves, and we are 100% pleased with the finished result.

Striking a balance between Service, cost and quality is always going to be hard, but I feel Generation Windows did just that. I would also like to shout out to Paul and Mark for looking after us as customers for the duration of the installation and encourage them to keep up the good work.

Generation Windows replaced our patio doors. They did a fantastic job, really tidy workers, cleaned up everything. The price was almost half of the other quotes we had. The quality of the doors is excellent. Highly recommended!

We recently employed Generation Windows to replace our old sash windows with double glazed units. We were keen to retain as much of the original Victorian look of the property and Generation Windows worked with us to ensure the old sash windows were replicated perfectly in more modern and energy efficient units. From the initial site visit, through quotation phase and fitting, they were responsive, listened, addressed any concerns. The fitters were incredibly polite and respectful and did a first class job. The house looks amazing. Rooms are warmer and quieter. Impressive work!

I can not recommend Generation Windows highly enough! Excellent products and service from everyone. I had 3-fold bifold doors and a new kitchen window fitted. The work was done quickly, cleanly and efficiently. They were happy to come back and check that I was operating the doors properly! I am delighted with the result!

I chose Generation Windows as my son had recently used them for replacement sash windows and was very pleased. I had porch doors fitted and I am delighted with them. The quality is excellent and the service throughout was fantastic. They were always punctual for appointments and kept me informed throughout of progress. Would definitely use them again and have no hesitation in recommending them.

We were recommended Generation Windows by our builder who recently used them on his own house. In regards to the work; we were astonished at how fast they worked considering how many windows we had. The installers Jim and Ryan were polite, friendly and always cleaned up at the end of the day. David stopped by to check all was going well and we happy. Please do give them a call. We would recommend them without hesitation.

Absolutely delighted! perfect Job--Don't use anyone else! We had another company replace our front door and frame 2 months ago which was disastrous the door frame was to big they bent the frame using a crow bar!! scratched our wood floor and hacked loads of plaster off. Needless to say we paid them nothing! We asked Generation Windows to save us! and not only was it less money but there SOLIDOR front door was double the quality! They turned up on time and made good all the damage the other company had caused. We are recommending Generation Windows to all our friend.

Generation windows replaced the sash windows in my first floor flat. They were exceptionally helpful and accommodating throughout the whole process. The works were carried out quickly to a very high standard, and the area was kept immaculately tidy throughout the works. Everyone that I dealt with was kind and polite and responded to any queries that I had (however silly) quickly and with respect. I would happily use them again, and cannot recommend them highly enough.

This company did a brilliant job replacing all of our doors and windows. Everyone we met was so friendly and professional, they made sure they protected any parts of the house they were working in and tidied up completely after themselves. Everything was finished to a really high standard as well. We’re very happy with the work done and wouldn’t hesitate to recommend them!

This is the 4th time we have returned to use David Flynn and his team. Initially to full double glaze the house, then six external doors (which have received many compliments), a small conservatory and now a bi-fold door. They offer quality products at a reasonable price. In additional David Flynn and his team at Generation Windows are pleasant to work with (although very demanding on the tea making!)

The lock on my front door was broken, only locking from the inside. A locksmith advised it would be cheaper to get a new door. I visited generation windows to get a quote and they replaced the lock barrel saving me lots of money, excellent! Will recommend them for sure.

I obtained a few quotes from several window installers but decided to go with generation windows. This was not only because their prices were competitive, but I found them to be professional and friendly. I had two large bay windows fitted, one set of french doors, and another small bedroom window. Generation windows were very patient and thorough in ensuring that my full requirements were met. During the day they installed, they were very professional and very careful in keeping mess and dust at bay. Can't fault them and they were very good at communicating with me and making sure I was satisfied with their work. I would definitely recommend Generation Windows and would use them again. I would like to get my front door changed soon, so may just well be in touch with them again very soon. Thanks for a good experience.

Generation Windows replaced the roof panels in our conservatory which turned out to be specialist and needed more than previously expected. Despite this the team made everything really easy and even simple by helping us pick the best products for us, keeping us informed and really going above and beyond. So easy to communicate with.
