A customer has asked if i can remove the paint that covers the bottom half of her house.Is there a chemical i can apply then blast with my turbo nozzle or is sand blasting her only option.

Nightmare job as some of the initial coat of paint will have penetrated the brickwork. If you take it on get a caveat signed that there might not be total removal, even with sand blasting which can also damage the face of the bricks.
There have been threads before about this, do a search and they might come up.
