Had lots of rooms fitted out by Benchmark Windows over the years. The biggest project was our kitchen extension with bifold windows, atrium and windowed roof. Outstanding ideas, outstanding customer service and fitting, and perfect after sales service. Can highly recommend them and we wouldn't look anywhere else for our windows.
