Brushing entire house?

[Tim S]

I have been asked by a homeowner to give bid on washing his 2-story house. He states that he rented a power washer before to clean it himself, but "it didn't work." He advised that the entire house will probably need to be "washed with a brush."
Before going out to look at house, I asked what cleaning chemicals he used, type of siding, if he had tried to brush, last time cleaned, etc. His answers:

cleaning chemicals - "non used" (huh?)
type of siding - "textured (vinyl) covering over aluminum siding"
prior brushing - "no"
last time cleaned - "a long time"

Some advice/experience in the following areas:
What special problems (if any) with this type of siding?
How to price with/without brushing?
Special problems (access around house, porch, etc) -
see pictures by clicking link below
Homeowner is especially concerned about flowers around house
Paint peeling around most windows (release of liability?)
Type of lift to use if customer insists on brushing? (have x-jet)

Havent been able to do test wash due to homeowner out of town for a few days. Will do that when he returns, which may answer most of the questions. In the mean time any advice or suggestions would be greatly apppreciated.

Thanks in advance.

Tim, forget about the brush and lift. The X-Jet and chemical should be all you need. The X-Jet should deliver about 1,000 psi with a 3,000 psi @ 4 gpm machine. The best place to check your pressure output is between your hose and gun. If you don't have a ball valve install one at the end of your hose. Just a tip.

Tim,
If you do a search on this board, you can find recipes for some good house washing brews.

As Steven stated, you don't need a lift. Just shoot your chems on with the x-jet, and wash using an extension wand. If the gutters need a little brushing, use a small 12" brush on an extension pole.

It should be a piece of cake.
