The installation was undertaken over two weeks in February by Rob Wood. The installation was completed in a timely manner and each day Rob ensured that everything was left as clean and tidy as possible. It was clear that Rob is diligent and hard working, and with quite extraordinary stamina and skill. He was unfailingly courteous, cheerful and considerate of our comfort. He demonstrated to our decorate the way the windows work and how they can be removed for painting. We are very pleased with the end result and our neighbours are quite envious. We would be very pleased to recommend Ventrolla to anyone considering having new windows installed.
