INVICTA are the best window cleaning firm I have experienced in 10 years managing buildings.
Competitively priced but worth their weight in gold, absolutely excellent standard of finish, beyond what I thought was possible in terms of "cleaned" from 7-10 other supposedly professional commercial window cleaning firms I have used serving Tayside. Professional and always on time, also flexible dependant on business needs with no price fluctuation.
Matthew and Pete always excellent and will even return to a job without additional charges if they are not happy with the finish, Matthew always his own most severe critic for standards, way beyond my expectations for large scale glass standard of finish...
If you pay someone else to clean your windows, you are wasting your money.
