Overall I am very happy with the entire experience of dealing with Dolphin Windows. From the start the communication was at an excellent level and I never had to chase for anything. The cost of the windows was very reasonable with no unexpected costs involved. They were also very helpful in suggesting cheaper options for window style choice. The windows were installed on time and they cleaned up very well after the work was complete. All timelines were met through the process. A super job!

Gave an honest appraisal of the door which will need replacing and still managed to get the lock to work as a short term measure. Many thanks.

Amazing service From Alen and his team. His quote beat the competition by far, but without any compromise on the windows. We were only planning to have new wooden double glazed windows for the front of the house, but were actually able to have new windows for the whole house. Alen also made suggestions which we had not thought about. He said we would have beautiful new windows and he has delivered. Clean, polite and kept informed throughout the process. Wholeheartedly recommended.
