Quite simply, all grassrootDESIGN work is guaranteed for 12 months. If something breaks because of the work I have done, let me know and I will fix it free of charge. Even if it's not the fault of my work, and even unrelated to my work, let me know and I will have a go for you. My thinking is that if I look after you, you'll come back with more paid-for business down the line.
You can read more about the guarantee and why I brought it in here.
