I have been using Trevor Porter for 11 years to clean windows at blocks of flats. Always done well and on time. In that time, only once was a window missed (out of about 90 in that block) and they were back the next day to rectify. First class service, thoroughly recommended.

We have been using Trevor for many years to clean our windows at home and at our office. We have never had any problems with the work carried out and would definitely recommend him to others. Always friendly and the work is excellent !
