Quick questions before starting

Here are two quick questions we think are worth covering before we get too ahead. 

How difficult is this to do? 

Pressure washing vinyl siding is an easy task for a professional. However, it lies in the easy to medium category for a beginner because you have to be careful with certain things, which we’ll discuss later.

Items needed

Other than a pressure washer, here’s what you’ll need:

  • Detergent: $20 to $25
  • Extension wand (if you have a 2-story home): $12 to $18

What PSI level is best for vinyl siding?

Vinyl siding can bear higher pressure than wood or window panes, so 2000 to 3000 PSI  is a good range

Too much pressure can cause damage, and water can seep into the walls.

Here’s a step-by-step process to pressure wash vinyl siding

For single-story homes

1. Examine the walls

First, take a careful look at the exterior walls of your home to understand how dirty they are. 

Look for cracks or breaks; if you find any, restore them before washing, or you’ll do more harm than good. Applying low pressure (about 1500 to 1700 PSI) is best if your siding is old or brittle.

2. Clean up the surrounding area  

Next, start by preparing the surrounding area. Remove any outdoor lights and if you have any furniture or plants, move those too or cover them. Be on the lookout for electrical outlets as well.

3. Prepare your pressure washer 

Now we have to set the correct PSI and nozzle. 

As mentioned above, the optimum PSI range for this project is 2000 to 3000 PSI. 

As far as nozzles go, 40 degrees is the most appropriate for vinyl siding.

Lastly, prepare your cleaning solution. You can use mild all-purpose detergent or solution specifically made for vinyl. 

Just be sure to avoid the following:

  • Corrosive cleaning solutions
  • Detergents having a high quantity of bleach

4. Spray soapy water

Here comes the fun part. Let the water flow, and spray your solution from bottom to top. Then, just take care of the following:  

  • Stand almost 5 feet away 
  • Don’t hold the nozzle perpendicular to the siding (always spray at an angle)

5. Rinse

Let the soap sit for 2 to 3 minutes, then rinse. Remember, don’t wait too long because we don’t want the soap to get dry. When rinsing, start from the top to get a streakless finish.

For a 2-story house 

All the steps are the same here, but there are a few minor adjustments. 

For a 2-story house, increase the pressure and reduce the angle. Doing so will allow you to access those hard-to-reach spots near your roof.

Tips and safety considerations

Safety first! Be sure to follow these tips: 

1. Don’t use too much pressure

Using too much pressure can crack or damage vinyl. Stick within our suggested range and always test a small section before moving to the main area.

2. Avoid using a ladder

Don’t use a ladder to wash second-story siding. It’s risky- Instead, use an extension nozzle to reach the height. Only use a ladder to secure electrical outlet and protect specific areas from potential water damage.
