Brian's quote was competetive and reasonable for the work required. He took time to listen to the type of door and positioning I wanted, and was well prepared with brochures of available door styles to choose from.
I wasn't around on the day of the installation, but my partner tells me that the fitting team were polite, considerate, hard working, and left the area clean and tidy.
The end result is exactly what I was wanting, well installed and will last for many years to come. Thanks Brian and team.
