Since our beginning in 1979, the company has been a window cleaning thoroughbred, we do not offer window cleaning just as an add on service, unlike most of our competitors who are office companies subcontracting the window cleaning (normally to a couple of guys from the pub who have little experience, training and most importantly have inadequate insurance).
