Like Stuart says,
Yes people do expect it to cost less but remember this.
1) Your working up a ladder.
2) You cleaning gunge and smelling debris out of gutters!
3) The end job is a long process
4) The client is normally too lazy or scared of height!!
Its your time, so charge for it.
Think how many houses you could clean in the same time. If your out of pocket cleaning gutters then why do them?
Best of luck,

p.s. squeegees are here today and can be gone tomorrow. You could fit a brand new blade, clean a window, miss a bit of sharp grit on the glass and put a nick in your blade straightaway!! Its just pot luck how long they last.
