Dirty siding, algae stains, and bug marks make many homeowners start searching for how much to power wash a house before booking a service.
The confusing part is that prices can vary a lot. One quote may seem reasonable, and another can feel way too high for the same house.
In this guide, you’ll learn what pressure washing usually costs, what affects the price, and how to compare quotes so you know what’s normal before paying for the job.
Key Takeaways
- Most homeowners pay around $212 to $448 to power wash a house, with the average cost sitting near $311.
- A standard siding-only house wash often costs $300 to $500, especially for homes with easy access and light buildup.
- Pressure washing usually costs $0.10 to $0.50 per square foot, but height, stains, siding condition, access, and setup can change the final price.
- A 2,000 sq ft house may cost $200 to $1,000, depending on how dirty it is and whether extra services like roof cleaning are included.
- Two-story homes, roof washing, heavy mildew, and tight access usually cost more because they require more time, tools, safety work, and cleaning solution.
- Compare quotes by service, not just total price, and ask companies to separate siding, roof, driveway, and add-on costs before you decide.
How Much Does It Cost to Pressure Wash a House?
Most homeowners pay around $212 to $448 to pressure wash a house, with the average sitting near $311. But that number can move up or down fast depending on the house size, height, siding condition, and what’s included.
That’s why two quotes for the same house can look completely different.
- Basic house wash: A smaller or easier one-story home may cost less if the siding has light dirt and easy access.
- Average house wash: Many standard house pressure washing jobs land in the $300 to $500 range, especially when it’s just siding.
- Heavy buildup: Mold, mildew, algae, bug residue, and years of dirt can increase the price because the job takes more time and cleaning solution.
- Roof or soft washing included: This is where prices jump. Roof cleaning is usually more expensive because it involves chemicals, safety, slope, and careful treatment.
- High quote warning: Example, a homeowner with a 1.5-story, 1,800 sq ft home was quoted $2,200 for roof soft washing plus siding. Many people felt that was too high and suggested getting more quotes.
Simple rule: a normal house wash may cost a few hundred dollars, but roof cleaning, height, access, and heavy buildup can push it much higher.
How Much Does It Cost to Pressure Wash a House Per Square Foot?
Pressure washing a house usually costs around $0.10 to $0.50 per square foot. That range is wide because contractors are not just pricing the size of your house. They are also pricing time, difficulty, setup, water access, siding condition, and risk.
Here’s what affects the per-square-foot price:
- Easy siding: Clean vinyl siding with light dirt usually falls closer to the lower end of the range.
- Mold or mildew: Green algae, black streaks, and heavy buildup can push the cost higher.
- Two-story or tall areas: More height means more time, tools, and safety work.
- Tight access: Narrow side yards, landscaping, fences, or steep ground can make the job harder.
- Minimum service fees: Even small jobs may start around $150 to $175 because the company still has travel, setup, and equipment costs.
For example, a 2,500 sq ft home may cost around $350 to $425 if the job is fairly standard. But if the same home has heavy algae, second-story peaks, or extra surfaces, the price can climb.
How Much to Pressure Wash a 2,000 Sq Ft House
- For a 2,000 sq ft house: Using the common $0.10 to $0.50 per sq ft range, the rough cost can land around $200 to $1,000.
- For a normal siding-only wash: Many homes may fall closer to the middle if the siding is easy to reach and not heavily stained.
- For roof cleaning included: Do not compare it to siding-only pricing, because roof soft washing is usually a separate, higher-cost service.
How Much Does It Cost to Pressure Wash a Two-Story House?
A two-story house usually costs more than a one-story house because the job is harder to reach and takes more time. Around $120 to $1,600, depending on size, buildup, access, and difficulty. That does not mean every two-story job should be expensive. It means the setup matters.
- Basic two-story siding wash: If the home is easy to access and only lightly dirty, the price may stay closer to the lower or middle range.
- Tall peaks or awkward access: Steep ground, tight side yards, fences, or landscaping can increase the cost.
- Mold, mildew, or algae: Heavy buildup takes more cleaning solution, dwell time, and careful rinsing.
- Soft washing instead of pressure washing: Many two-story homes need soft washing to protect siding, windows, and trim.
- Roof cleaning included: This should be priced separately because roof work involves more safety risk and stronger cleaning methods.
Simple rule: a two-story house costs more because height adds time, difficulty, and safety work.
How Much Does It Cost to Power Wash a Mobile Home?
Power washing a mobile home usually costs around $50 to $150 for a basic wash, with many standard single-wide jobs landing near $75 to $125.
That price can go higher for double-wide homes, heavy dirt, algae, oxidation, skirting stains, or difficult access.
- Single-wide mobile home: Usually costs around $50 to $125, depending on size and condition.
- Double-wide mobile home: Often costs around $75 to $150+ because there is more siding, trim, and skirting to clean.
- Per-foot pricing: Some contractors may charge around $0.50 to $2.00 per linear foot, depending on the job.
- Vinyl or metal siding: These surfaces often need soft washing instead of strong pressure to avoid damage.
- Add-ons: Roof cleaning, oxidation removal, heavy algae, or deep skirting cleanup can increase the total.
Simple rule: a basic mobile home wash may cost $50 to $150, but bigger homes, fragile siding, and add-ons can raise the quote.
How Much Does It Cost to Pressure Wash a House and Driveway?
Pressure washing a house and driveway together usually costs more than a siding-only wash, but it may be cheaper than booking both jobs separately.
Driveway or sidewalk cleaning can often add around $100 to $300 or more, depending on the size and condition.
- House wash only: Often falls in the few-hundred-dollar range for standard siding cleaning.
- Driveway add-on: Usually adds cost because concrete needs different pressure, surface cleaning, and sometimes pretreatment.
- Oil or rust stains: These may cost more because they need extra treatment.
- Large driveway: More square footage means more time and water use.
- Bundle pricing: Some companies may offer a better total price because they are already on-site.
Example: If the house wash is $350 and the driveway add-on is $200, the total may land around $550. But if the driveway is large or heavily stained, the final price can be higher.
Simple rule: ask for the house and driveway prices separately so you know exactly what you’re paying for.
