Its very simple, if you need to put your prices up, just do it. You will lose customers over it, but its do that and stay profitable or be an apologetic bottom feeder and go out of business in 5 years I see it all the time. Its that simple. Keep your prices low, you will keep customers who do not respect you, value you, and you will loose heart, lose interest and your quality of work will decline.
I'm going back to work on the 18th April, and I have a very close friend who has been covering some customers for me who still insist on having the windows cleaned and paying him directly. On average I am 40-60% more expensive than him. 4 of my jobs are 10 or 11 of his, and they take less time. Its opened his eyes and he now sees the light, he put his prices up the same, lost a bunch but is making more money for less work.
