Dan, in these time you have to be multi skilled to make your money. My bread and butter like most on here is carpet and upholstery cleaning, but i could not survive on that alone.
So i have ad on,s to my business which all together ad up to a good income over the year , these are,
Curtain cleaning
Rug cleaning and repairs
Fire and flood restoration
Fogging and ozone treatments
Leather cleaning and repairs
Pressure washing
Tile and grout cleaning and restoration
Leather work i get around one or two jobs a month on average, which prob pays about £5k a year.
