I live and work within a few miles of Tihlson and clean nurseries on a regular basis, usually three times per year.
They are always cleaned on a Saturday, or Sunday morning and are straightforward, with the carpeted areas cleared in advance.
Takes about two hours for each, working alone, using Texatherm and I charge €120 for each clean, which I regard as a good return.
I've been involved in letting cleans for many years and really hate them. Just did a renovation clean in a rented flat at the weekend, which had been supposedly cleaned by someone else.
Cleaned properly, the result was excellent and well beyond the owners expectations, but, due to the circumstances, I undercharged a little, my autopilot looking forward and considering credibility, before profit.
Good luck Tihlson .
I presume you're new to the business, whereas I 'm trying to escape.
