Quick Answer
For the whole house, especially if it's two stories, has delicate siding, or a wood exterior, you're generally better off calling a pro. A pro will cost you $300 to $800 but will use the correct pressure and detergents, minimizing the risk of causing thousands in damage while achieving a more thorough and lasting clean.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Do a walk-around and identify all the surface materials you need to clean, like vinyl, brick, wood, or stucco.
Step 2
Look closely at the type of grime – is it just dirt, or is it living growth like mold and mildew?
Step 3
Decide on the right machine and pressure. For most houses, a low-PSI electric washer is better and safer than a big gas one.
Step 4
Pick the right nozzle (start with the white 40-degree) and test it on a hidden spot to make sure you won't cause damage.

When to Call a Professional Handyman
- Call a pro if you need to clean second-story walls or any high, hard-to-reach areas that would require a ladder.
- Call a pro if your house has delicate surfaces like stucco, painted wood, or old, brittle siding that can be easily damaged.
- Call a pro if you have significant, deep-set mold and mildew that requires specialized chemical treatments (soft washing).
- Call a pro if you don't have a full day to waste and want the job done quickly, safely, and with consistent, professional results.
Prevention Tips
- Clean your gutters regularly to prevent overflows that stain the siding.
- Trim back trees and bushes at least a foot away from the house to improve airflow and reduce mold growth.
- Give the house a quick rinse with a garden hose a few times a year to wash off loose dirt and pollen.
- Make sure your sprinklers are aimed away from the house to prevent constant moisture and water spots.
