    • Windows and door excellent. Did not think I would have such a good job done, workmen never stopped working till they had finished what they were doing. People passing comment on the colour and ask who did the work. Certainly recommend this company no dust or debri on carpets in bedrooms or round the outside of the house. All left clean.
