[steveing]

Hope some body can help i had my garden done last july the contractor used Bradstone 600mm textured grey and blue which all looked great.

But they have started to fade around the edges and before i ask him to come and look i wanted to see if anybody could give me some advice is it normal or it there a problem with the slabs just to add thye have not been washed with a jet wash just a stiff brush and bleach solution as per the instuctions from him
