This really is a difficult question because it depends on so many things.
The type of carpet.
How dirty it is.
How accessible is it?
What type of staining?
What does the customer want?
I prefer to speak to each customer and find out as much as possible before quoting. I am a very experienced carpet and upholstery cleaner, confident in my own ability and will happily quote over the phone or visit to assess.If you prefer send me an e-mail with details of the cleaning you require.
Give me a ring and i will happily discuss your requirements.
