One customer said after 5 years of cleaning £19 job all day long,they've had a cheaper quote and he will also clean the sills or cills depending on you choice of spelling,so did I ffs,ground floor cills/sills can be cleaned to a good standard with wfd,as we all know,first floor is a bit of hit and miss as you can't see,or should I be getting my ladder out to do first floor,,,? Not for me
