There is absolutely no money in pressure washing even down south, I'd stick to what you are doing at the moment, Look at Mike Halliday doing this for years, 85% of customers over retirement age, packs his kit away at the end of October the latest, what chance do we have down here in London with all these city types , Rich Russians, Arabs, CEO's living in private estates, buying up houses and not spending any money? Might have to re-think my career!!!!
