We were very impressed with Dan’s attention to detail, standard of workmanship and care taken. We were happy with the original installation but it is a tribute to Dan that he identified an issue and came back to do more work until he was satisfied it was just right. Dan kept us informed of progress and was very pleasant to deal with. When we had an issue with planning permission Dan provided detailed drawings of the sash window specifications. No hesitation in recommending. Windows look lovely.
