What to charge per sq ft to pressure wash a building and parking lot.

No quick answer, look at the job details, like what kind of siding on the bldg, is it on a hill or flat land, easily accessible, if your first job of this kind, estimate how long it will take, how many people do you need, one or two, build in the profit you expect, then take time and measure the sq. footage to be power washed, divide that by the total of your time and profit. I have done power washing commercially and ea job is different. But I do think you can come up with some sort of price per sq foot.

In Atlanta, those with hot water washers, normally get about 5 to 10 cents a sq foot for paking lots. They will be using of course flat surface cleaners which clean alot better than just the wand.

Since cold water will not clean as well, most parking lot cleaning is always done with hot units which will clean the oil and grease better.

For single familiy homes, most charge a flat fee of about 100 to 125 dollars for a home.

next of course doing commercial buildings will be different but they will get about 10 cents to 20 cents a running foot for one story commerical buildings,

also remember that the standard unloader can handle a two, and maybe a three story building, but over that, the unloader can not handle the increased back pressure.

But also the type of cleaning, merely washing it off is one thing, but on some buildings, you have to bush soap on, and use a brush to clean, since pure pressure can't be used just by itself on brick and wood, since it can also gouge.

Also there make a smaller flat surface cleaner for walls, that are used on other various surfaces for a more uniform clean.

And lastly you did not ask for one of the largest paying item, semi trucks and thier trailers.

Also there are alot of jobs taking decals off of trailers and the such, most of these are bid jobs.
( you will need hot water with at least 3000 PSI and 4000 PSI works better for decals off of trailers)
