What is the best & easiest way to Power Wash our House?

Looking to Power Wash our House and wanted to do it myself to save on the Money of hiring someone else to do it as I have in prior years.

So was wondering what is the best way and the easiest way to Power Wash a House?
That is what Power Wash system & Detergent do you think is the best?

Well lololooo,

After reading through all of the comments and suggestions regarding cleaning the exterior of your house, I am curious. How much money did you save taking into consideration your time spent to acquire the needed tools and supplies, the cost of the supplies and the rental, and the time spent for the actual cleaning?
Thanks

I don't know the best way, but you want to be careful not to spray the water up under your siding. The insulation behind the siding is not supposed to get soaked and the pressure from a power washer can force the water up and under the siding. It can cause a mold problem later. You want to spray directly at the house, not up on an angle which may force the water under the siding.

These are lots of good Answers to my Questions and I thank you all.
So just to be sure, let me put in one place what I need to do as per your suggestions and please let me know if I am right or any if you have different suggestions.

So to Power Wash our House I need do:

1- Apply Soap/Detergent via the Pressure Washing machine to one section of the House from bottom to the Top of the House.

2- Then change the nozzle head to a much more powerful pressure and then Wash with Water only from Top to bottom.

3- Repeat the process in the next section of the House.

My Questions then are:

1- What should be the width of the House that I Soap & Wash one a time?
2- What about the 2nd Floor? Do I change the head for each Soap & Wash cycle as I go from lower floor to 2nd floor?

3- What about irregular surfaces such as the ceiling of the enclosed Deck?

Thank you all.

I would wash with the TSP the one side at a time . Rinse with clear water as you finish
each 20-foot section. as for the 2nd floor, if you're spraying from ground level just
increase the pressure on the Power washer. Keep in mind that if you do use a Ladder the
start-up can possibly knock you off the ladder,You should always spray horizontally (3-4
feet wide area) Never let the detergent sit on the surface for more than 10 minutes.and
the ceiling spray on an angle so that you do not get sprayed

lopolooo 6 years 5 months ago

Hey Vince.
1st, just to be sure: so you have lots of experience with Power Washing?

If yes, Just to be clear:

1- what is "TSP "?

2- So you are saying Power Soap spray 20 Feet of the House and then Power Wash that 20
feet section and then move on to the next section?

3- About reaching the 2nd floor, I think it is too unsafe to use a ladder, and been told
same by others, so then how can one possibly spray the 2nd floor section horizontally?
Not possible.

vincespagoli 6 years 5 months ago

Make sure you cover all electric outlets and always avoid lights since water can create a
short circuit. Before you pressure wash black spots and clean top corners, identify
whether you are dealing with fungus or just extremely dirty areas. Use more focused nozzle
for areas with heavy mildew, dirt or fungus. You're Welcome

vincespagoli 6 years 5 months ago

Don't use a ladder if you're not sure . spray the second floor diagonally to be safe and
if necessary use a more focused nozzle. just be careful not to get sprayed
yourself...(Spraying horizontally keeps the solution from going in in window and door
Frames and between glass.) but if you're not experienced, Stick to doing it from the
ground and Power Spray Diagonally.

vincespagoli 6 years 5 months ago

TSP is.TRISODIUM PHOSPHATE... just uttering the name sends chills down the spine, doesn't
it? For those of you who don't know, trisodium phosphate was a synonym for pure cleaning
power!! For many years, compounds similar to this were used in clothes and dishwashing
detergents. These compounds could get any stain out of your custom sweatshirts and get
all the grime off of those dirty dishes...

I hope All Goes well and that this Information Helps...Good Luck....Vince

lopolooo 6 years 5 months ago

vince, thanks for all the good info. Very helpful.
With your help I think I am going to give this a try tomorrow.
Hopefully I wont destroy our house or kill myself.
One question though:

Should I go with low or high Pressure?
And if I rent a 2500 PSI pressure washer from say HD, how do I set it at low vs high?

vincespagoli 6 years 5 months ago

Rent one that is adjustable and start with a low setting and as I mentioned test first and
adjust or increase the pressure till it cleans as you want....there should be a Knob and
by turning it Clockwise - that should increase the pressure.. explain to the clerk at the
rent - all that you want to rent one that is adjustable...most of the are.. but the
cheaper ones aren't...good Luck!!

lopolooo 6 years 5 months ago

Man I beginning to think that may be I should hire someone to do it.
This seems to me more work that I bargained for.
We shall see. Fingers crossed :)

lopolooo 6 years 5 months ago

It depends if your home has Aluminum siding, Stucco, Brick or if its painted. Don't power wash your home if you think its been painted with lead paint (before 1978). It depends on what is being removed. I would rent a pressure washer from a tool rental center or even at Home Depot. A good pressure washer will make it easy to reach second story of a home without the use of scaffolds or ladders and I think a 2500psi minimum would be enough. You can use a number of industrial strength materials but for small jobs I would use KRUD KUTTER Concentrated Multipurpose Cleaner ($11 to 13) or KARCHER Concentrated Multipurpose cleaner which you spray on and leave for 5-10 minutes to penetrate and then wash off. It is recommended for use on aluminum, vinyl and wood siding, awnings, gutters, porch screens, driveways, pool areas etc... and is safe for people, pets and plants. Any tool rental center or representative at a Home Depot or Lowes Store will be knowledgeable and willing to help.

I concure with vincespagoli. The only thing to add would be make sure the pressure washer' s power is at least 2500 psi.

If you don't own a Power washer, You need to go to a rent al store and rent one. make sure it has detergent spraying capabilities and that it has a high power jet spray.
Use a ladder and start at the top of the House and work your way down . now if the material you're washing is wood that's painted be very careful as the power washer can also remove the Paint...if it colored vinyl you should be OK...test a small out of the way area first. keeping in mind that a power washer can remove paint from a car. so if its material that's been painted don't spend to much time on one spot. if you can turn down the force then do so.. but test a small area first. Any hard to remove dirt clean by Hand.

Vince, yes I will be renting.
So Question is what machine or machine spec should I insist on?
And what Detergent should insist on?

Also I was told by many to apply the Detergent not from the top of the House but from
bottom to the Top. And when power washing with water then go Top to Down. And not to use a
ladder but an extender to reach 2nd floor.

vincespagoli 6 years 5 months ago

Rent a Power washer with at least 2500 psi and if the house isn't too high, an extender
may be sufficient, I prefer to use ladders as it will give you a closer view and with an
extender, the pressure depletes as you reach for the top. as for detergent TSP (
TRISODIUM PHOSPHATE) Is a great cleaner. if you have a lot of mildew add some bleach The
TSP and bleach act in concert to both kill the mildew and remove its characteristic
stains. TSP is a strong cleaner make sure you Read the Instruction

vincespagoli 6 years 5 months ago

As I mentioned in earlier comments ALWAYS test an out of the way area or a piece prior to
doing anything. TSP is a strong base and can cause severe eye damage and can burn
unprotected skin.Wear suitable clothing and eye protection. Keep away from skin and out of
gloves....as far as starting from the bottom up (the Idea is that way the Detergent has
more time to work before being rinsed off. If the home has a lot of dirt and mildew, then
I would agree. Just make sure you rinse from the TOP DOWN

I believe that the exact procedure is going to depend upon several factors:
What is the surface material that you are going to wash- (Wood, Concrete, Stuco, etc.)
How high is the house-
What is being removed - (Mold, Dirt, Rust, Moss, etc.)
Since you have not done this before, I assume that you will need to either rent or purchase a Power Washer ..The rental agency or dealer should be knowledgable and able to provide you with the details that you require.

allbrands, In reply to your answer:
1- Hardy Plank mainly, plus Wood
2- What is being removed is normal dirt & mildu
3- And yes, I have not done this before, my 1st time! Fingers crossed :)
And yes, I want to rent a machine since I am selling this House and moving into a High
Rise Apt.

allbrands 6 years 5 months ago

I am not an expert in power washing but I would think that you need a machine that will
generate 2500 to 3000 psi & probably plain old TSP as a detergent. As posted above testing
a small not highly visible area is extremely important for determining the pressure
required and evuating the sucess of the process. I still also strongly suggest
obtaining
the advise of the dealer or rental store ! Good Luck !
