I'm no hard floor expert. Got a basic grounding through ServiceMaster (handy to be the only recommended company to maintain Amtico
) and watching/learning from the guys I started with (also recognising where they were going wrong!).
Asking lots of questions, always trying to understand in greater depth what exactly floors are and how to maintain them.
Trial and error
Not meaning I've ruined peoples' floors, although there have been a few close calls along the way! Always striving for perfection, so if a job doesn't go exactly as I'd wanted, I'd be asking why and how could I improve.
You learn a lot from going out to look at jobs, making no promises or commitments, and doing a little testing. In the past (and I'm sure I'll do the future too) I've taken an enquiry and thought "Ooh that sounds scary" but gone out to look, got as much info as possible from contacts, forums etc, then bought some stuff and gone back and done a bit of testing (free of course) to allow me to find out if I can do anything and how to price it.
To be honest I have never pushed hard floor work too much other than Amtico. Stone, slate etc are much harder work and you can never achieve the hourly turnover rates as with carpet cleaning.
It seems bonkers but I've encountered this situation many times: A customer might have a slate floor that cost them £100 a metre and carpet that cost them £30 a metre - you quote them a rate of e.g. £4/m for the carpet and they snatch your arm off but try getting £6/m for stripping and sealing the floor and they'll go into spasm :
There seems to be much less perceived value in hard floor work, maybe because folks don't think there's anything technical involved with it
A few times with stone etc I've ended up slogging my balls off for what has equated to as little as £20/hour turnover (margins are much less than CC due to materials) - it can be physically knackering too, giving you that "why am I doing this" sort of feeling at the end of the day. So that's why I use my acquired wisdom and quote high for these sort of floors - the few that I do get, I enjoy, and the others can "get the cleaner to run a mop over it" for all I care
Vinyl is a walk in the park, get to grips with the basics of it and start advertising Amtico/Karndean is my recommendation
