I have a deck to powerwash. one deck is 10' x 10' second story with stairs that go down the other deck is 5' x 8' on the ground. has lattice sides flat railing on top. any ideas for price. homedepot has a power washer 2600 psi 5.5 honda motor, will that be enough to do the job

I can't help on price(never actually done a paying pressure washing job), but I can tell you that even the cheapest electric pressure washer can do decks. Wood is the easiest material by far to clean using pressure washing.

We get $1.15 per sq ft to clean only and $2.25 per sq ft for full restoration.2600 psi is WAAAAYYYYY to much psi to use on wood.With the right chemicals and 800psi they will come super clean.
Does the deck have stain on it now or is it unsealed wood?Measuer every peice of wood you see,not just the floor boards.There is almost as much sq footage in hand rails,lattice and ballisters as theer is in the floor surface on most decks.

thanks tim and scott, I been reading up on pressure washing, I hope this power washer has a pressure regulater on it. I think I will do this one to practice on. she has very low income, but Ill charge 150.00 for it.

Just use a tip that isn't so narrow in it's spray pattern.
