Highly recommend Dinas Windows! I ordered a door under supply only. The quality and pricing of the unit was excellent. The team were very helpful throughout the whole process, in choosing the most suitable door and arranging fast delivery.

We had all of our windows on the back and side of our house replaced by Dinas Windows, including a French door. We were very impressed by the speed, efficiency and courtesy with which the work was done. And we are very happy with the results.

The whole process from start to finish was faultless. All staff we had the pleasure of dealing with were most professional and polite. The door was installed quickly and cleanly and has made a tremendous difference to noise and draft problems. Extra keys could be ordered as we needed more than the 3 supplied. We would not hesitate to recommend Dinas windows or use them for future projects.
