How Much Does It Cost to Power Wash a House in Delaware County?
The cost to power wash a house typically starts in the several-hundred-dollar range, but the final price depends on the size, design, condition, accessibility, and cleaning method required. A straightforward one-story vinyl-sided home will generally cost less than a tall house with dormers, heavy algae, delicate exterior materials, and difficult access.
At Simple Clean LLC, our minimum service call is $350. That does not mean every house wash costs the same. It means we bring the proper commercial equipment, cleaning solutions, insurance, training, and property-protection process to every project rather than pricing a professional service like a quick rental-machine job.
After more than 20 years of working on homes throughout Media, Delaware County, and Chester County, I have found that homeowners usually care about two things: what the work will cost and whether their property will be treated carefully. Both questions deserve a clear answer.
Here are the five biggest factors that determine the cost to power wash a house.
1. How Large Is the Home?
The size of the home affects the price, but square footage alone does not tell the whole story. A wide ranch home may have more exterior surface area than a compact two-story house with the same interior square footage.
Contractors also need to consider attached garages, additions, walkout basements, enclosed porches, tall gables, and other exterior sections that increase the amount of siding being cleaned. A listing that describes a home as 2,000 square feet does not necessarily describe the amount of exterior surface involved.
This is why Simple Clean LLC uses scope-based pricing instead of relying on a rigid price-per-square-foot formula. We look at the actual home, the surfaces being cleaned, and the work required to complete the job safely.
In many cases, clear exterior photos are enough for us to provide a fast, contactless estimate without scheduling a separate sales visit.
2. How Tall and Complicated Is the House?
A taller or more complicated house usually costs more to clean because it requires additional time, equipment, hose management, and careful application. Three-story rear elevations, steep hills, dormers, turrets, roofline peaks, and narrow spaces between homes can all affect the scope.
Access matters more than many homeowners realize. A two-story home on level ground may be relatively straightforward. The same home built into a steep Chester County hillside could have a rear wall that effectively reaches three or four stories from the ground.
After hundreds of local house washing projects, I have learned that the hardest-looking section is not always the biggest one. A small upper dormer above a roofline can require more planning than an entire open side of a house.
Professional soft washing equipment allows us to clean most siding safely from the ground. That reduces unnecessary ladder use and avoids blasting upper siding with excessive pressure.
3. How Dirty Is the Exterior?
Normal green algae is usually easier to remove than years of heavy organic buildup, black streaking, lichen, artillery fungus, oxidation, or deeply embedded staining. The type and severity of the contamination can affect both the price and the expected outcome.
Most routine house washing involves treating organic growth with an appropriate cleaning solution and then rinsing the surface using low pressure. However, a neglected home may need additional dwell time, repeated applications, or more detailed rinsing around trim, gutters, and shaded areas.
Not every mark is removable through standard house washing. Oxidation, rust, paint failure, sprinkler stains, and artillery fungus may require specialized treatment or may not be safely removable at all.
As a PWNA-certified House Wash Specialist, one thing I tell homeowners is that an honest contractor should explain the difference between dirt that can be cleaned and permanent surface damage. Promising that every stain will disappear is not professional. Setting accurate expectations is.
4. What Exterior Material Is Being Cleaned?
The correct cleaning method depends on the material. Vinyl siding, painted wood, aluminum siding, stucco, brick, stone, Dryvit, and fiber-cement products should not all be treated the same way.
Most residential siding should be soft washed rather than cleaned with aggressive pressure. Soft washing uses properly selected cleaning solutions and controlled rinsing to remove algae, mildew, and other organic growth without carving lines into siding or forcing water behind it.
Delicate surfaces may require lower solution strength, reduced pressure, additional testing, or a different cleaning approach. Loose paint, failing caulk, damaged siding, open electrical fixtures, and pre-existing leaks also need to be identified before work begins.
Because I personally work on every Simple Clean LLC project, the person evaluating the property is also involved in cleaning it. There is no disconnect between a salesperson’s promise and a subcontractor’s decision once the job starts.
5. What Is Included in the House Washing Quote?
A professional house washing quote should clearly explain which surfaces are included and which services are separate. Homeowners should not have to guess whether the price covers siding, exterior gutters, soffits, fascia, porches, foundations, chimneys, or detached structures.
A standard house wash generally focuses on the exterior siding and other accessible surfaces included in the written scope. Roof cleaning, interior gutter cleaning, concrete cleaning, deck cleaning, and specialty stain removal are usually separate services because they require different equipment, solutions, and processes.
The cheapest quote may also exclude important preparation. Before cleaning, we inspect the property, identify potential water-entry points, protect sensitive areas, and thoroughly pre-rinse nearby grass and landscaping. We continue managing and rinsing vegetation during the work rather than treating plant protection as an afterthought.
With 200-plus five-star reviews, we have found that homeowners value a clear scope more than a vague bargain price. A detailed quote makes it easier to compare contractors fairly and prevents surprises once the work begins.
Frequently Asked Questions
How much does it cost to power wash a house near Media, PA?
Professional house washing generally starts in the several-hundred-dollar range, with Simple Clean LLC maintaining a $350 minimum service call. The final price depends on the home’s size, height, siding material, buildup, access, and included surfaces. Exterior photos are often enough to prepare an accurate quote.
Is soft washing more expensive than pressure washing?
Soft washing is not necessarily more expensive, but professional pricing reflects the complete process rather than the amount of pressure used. The price includes commercial equipment, cleaning solutions, training, insurance, preparation, plant protection, application, and rinsing. Soft washing is generally the safer method for residential siding.
How long does it take to wash a house?
Most routine house washing projects can be completed within a few hours. Larger homes, difficult access, heavy organic growth, complicated architecture, or multiple added services can extend the timeframe. We provide a more specific expectation after reviewing the property and confirming the complete cleaning scope.
How often should I have my house washed?
Most homes benefit from professional house washing every one to three years. Properties surrounded by trees, located near shaded or damp areas, or exposed to heavy pollen may need cleaning more frequently. Washing before growth becomes severe can also make ongoing exterior maintenance easier.
Can power washing damage vinyl siding?
Yes, excessive pressure can damage vinyl siding, force water behind the panels, mark the surface, and disturb loose sections. Professional house washing should normally use a low-pressure soft wash process. The cleaning solution addresses the organic growth so high pressure is not needed to produce a clean result.
Does house washing include the roof and driveway?
Roof cleaning and driveway cleaning are usually separate from a standard house washing quote. Each surface requires a different cleaning method, equipment setup, and amount of labor. Ask for an itemized estimate if you want the house, roof, concrete, deck, or other exterior areas cleaned during the same visit.

Yes, Simple Clean LLC serves homeowners throughout Delaware County and Chester County from our base in Media, Pennsylvania.
