We recently got some work done on our trading estate in St.Albans by these guys, and I am more than happy to say that they did an excellent job of cleaning up the pavements and pathways. The wall opposite our main entrance was also covered in graffiti and paint, and wasn't very nice at all. They have since removed all traces of the graffiti and it now looks new again. We would definately recommend the services of Herts Pressure Washing to anyone thinking of getting work done.
