I was very pleased with the whole experience for the following reasons.
The quote was quick, reasonable and detailed.
They started on the day agreed.
I was kept fully informed of progress, and asked my opinion on issues.
They worked continuously except for bad weather, but informed me when the weather was to bad to come.
They came on two weekends to make up for time lost.
The team were friendly and helpful.
The finished work was of a high standard with an eye for detail.

I am hoping to use the again for a future extension this year.
