I am interested in adding Graffiti removal to my business.
Could some one tell me, Is there much call for this service or do the councils handle most of it?
Is it a profitable add on?
Any advice would be appreciated 
a lot of the council work is tied up so you would find it very difficult attaining this type of work, we carry out a bit of this work and it is great as an add on as the jobs we get are well paid but not enough work to keep you going on its own.
i would advise going on a training course first as although it seems simple enough if the wrong chemical is used on some material you could cause a lot of damage, graffittihotline do a good course and their technical department always ready to give you good advice with any problem tags you will come accross.
