CALLING ALL OLD HIRED HANDS!! I NEED YOUR ADVICE ON THIS ONE!!
Now dont laugh too hard i'm new at this. But i need some good sound help.
I have had my own buisness here in San Antonio for almost a year now and have paid my dues cleaning alot of some nasty driveway's and sidewalks around town and i think i am starting to move up a bit.
Recently i got a call to look at a real nice house in town about 3600 sq. ft.
What they want is an exterior cleaning of the house as well as back patio.
The thing is all the low areas of the house as well as some high are covered with what looks like mildew and mold! Now, i have cleaned mold and mildew
but, this appears to be some serious stuff!

Im not one who's afraid to work hard, But on a job like this i think it's time to work smart!
If you look at the pic's i've posted you can see there are areas of the house you just don't want to use alot of pressure hell, if anyone has a tried and true chenical mix they use without fail i am all ears!!

I have checked out the archives looking for a good recipe and i think i found one but if anyone has something better please tell me!!

Here it goes:
from: JR Wood up in Pa.
2 gallons bleach
1 cup clear rinse tide
1/2 cup sodium hydroxide
the rest water in 5 gallon bucket
then spray through shurflo, let sit and rinse.

Once you see the photos what would you base your pricing on or would you run away from it!! I use a Northstar system that has 9hp. and delivers 3 gallons a minute under 3100psi.

Help! I need advice. check out the attachments.

On this one I'd use an X-Jet and 12% sodium hypochlorite. Brick and stone usually require higher levels of sodium hypo then say a vinyl sided house. The tide may leave a film on the brick. Use a car wash soap instead for cling. Definitley low pressure if you can help it. High pressure will cause efflorescence.

I agree with the xjet method. That's pretty much exactly what I would have said. Plus, here's THE best part about taking the time to do this job right. The before and after pictures will look amazing. I'm actually jealous of you.

sodium hypochlorite mix...

I can't tell anything from the pics except there's a lot of growth on everything.

Get some bigger pics, and I bet someone can help a little better with pricing.

Either way, I'd downstream.
