alot of the carpet cleaners window clean and window cleaners carpet clean
I started carpet cleaning 12 years ago but added window cleaning 2 years ago
I also sub my self out as a flood restoration technician (i was a IICRC and BDMA Tecnician many moons ago) as and when needed (it was the last floods and builders cleans that paid for my new van and system)
jack of all trades is the best way to go
cant fault it
