Residential power washing is an exterior cleaning method that uses pressurized water to remove dirt, algae, stains, and other buildup from surfaces around a home. It can be used as part of routine exterior maintenance or when surfaces need a deeper cleaning.
St. Louis weather, shade, moisture, and pollen can leave exterior surfaces stained, slick, or visibly dirtier over time. Power washing gives homeowners a way to address that buildup as part of routine exterior maintenance or before heavily used areas become harder to clean.

Why Do Homes Need Power Washing?
Homes need power washing to remove exterior buildup that can make surfaces slippery, stained, harder to clean, or less attractive over time. St. Louis weather and everyday use continually expose outdoor areas to moisture, shade, traffic, and debris from nearby trees.
- Algae on walkways, patios, and steps creates slick surfaces and a greater risk of slipping, especially in shaded areas that stay damp.
- Mold and mildew can spread across siding and outdoor surfaces, creating larger areas of visible growth and discoloration.
- Dark stains and discoloration can make an otherwise maintained home look neglected and drag down curb appeal. Some exterior stains also become harder to ignore as they spread.
- Oil, grime, and organic stains that sit on concrete and other porous surfaces may become harder to remove over time.
The right cleaning schedule depends on the property. How often your home should be power washed varies with shade, moisture, surface type, and exposure.
How Does St. Louis Power Washing Work?
Residential power washing uses pressurized water to loosen and remove buildup from exterior surfaces around a home. The equipment, cleaning method, and amount of pressure should change according to the material being cleaned and its condition.
A professional does not simply turn the pressure as high as possible. Nozzles, water pressure, cleaning distance, and technique change so tougher surfaces receive enough cleaning force without treating more delicate materials the same way.
For homeowners, the process generally includes:
- Identifying the surfaces being cleaned and their condition
- Adjusting pressure, nozzles, and technique to match the material
- Cleaning and rinsing each area without treating every surface the same way
What Is Residential Power Washing Used For in St. Louis?
Residential power washing removes buildup from exterior areas that gradually get dirtier through weather and everyday use. The goal is to clean each area without damaging the material underneath.
Driveways, Walkways, and Hard Surfaces
Hard surfaces usually show wear in a different way. Traffic and outdoor exposure gradually darken concrete or leave uneven staining around frequently used areas.
- Driveways often show oil spots and tire marks.
- Walkways collect grime in high-traffic areas.
- Concrete near garages and entries may discolor unevenly.
Decks, Patios, and Outdoor Spaces
Outdoor living spaces get dirty partly because people actually use them. Foot traffic, meals outside, wet weather, and seasonal debris all leave their mark, especially on areas used heavily during warmer months.
Material matters here. Wood needs a different touch than concrete, while stone may call for a different approach from either one. Poolside cleaning also changes with the material surrounding the pool and the type of buildup present.
Fences, Gates, and Property Boundaries
Some buildup shows up first along the edges of a property. Shaded fences, gates, retaining walls, and other exterior features often stay damp longer and receive less direct sun, giving algae and discoloration more opportunity to develop.
Windows, Railings, and Exterior Details
Smaller exterior features often need more surface-specific cleaning. Exterior window cleaning targets spots, streaks, pollen, and buildup on glass, while concrete walls, metal railings, and ironwork may tolerate a more direct wash.
What Chemicals Are Used in Power Washing?
Power washing may use detergents, degreasers, surfactants, or sodium hypochlorite-based cleaners depending on the surface and the type of buildup being removed. Water pressure already provides substantial cleaning force, so chemicals are not necessary for every job.
- Sodium hypochlorite-based cleaners are commonly used to break down algae, mildew, mold, and other organic growth.
- Degreasers can help loosen oil, grease, and vehicle-related staining on concrete and other durable surfaces.
- Surfactants and detergents help cleaning solutions spread across the surface and lift dirt before rinsing.
- Some surfaces need little or no chemical assistance. Pressurized water can remove dirt and buildup from many durable hard surfaces on its own.
House soft washing relies more heavily on cleaning solutions combined with lower water pressure on surfaces that need a gentler approach.
Can I Do My Own Power Washing in St. Louis?
Homeowners can handle smaller power washing jobs themselves, especially on durable surfaces such as concrete. Hiring a professional makes more sense when the job involves delicate materials, stubborn buildup, hard-to-reach areas, or several different surfaces.
| DIY Power Washing | Professional Power Washing |
|---|---|
| Lower upfront cost if you already own equipment or only need a small area cleaned. | Less time and equipment to manage for larger jobs or several areas around the property. |
| Works well for straightforward hard surfaces when you know how the material responds to pressure. | A professional is better equipped for mixed surfaces, delicate materials, and larger projects. |
| Using too much pressure or the wrong technique creates a greater risk of surface damage. | Professional equipment and experience help with stubborn stains and heavier buildup. |
| You handle the setup, cleanup, equipment, wet surfaces, and access yourself. | Better suited to large, awkward, or mixed-material jobs where the cleaning approach changes across the property. |
Residential Power Washing FAQs
How much does residential power washing cost in St. Louis?
Pricing changes with the size of the job and the surfaces involved. Access, buildup, and the amount of cleaning also affect the final price. Residential power washing costs depend on the property rather than one flat price for every home.
What should I look for in a St. Louis power washing company?
Look for clear quotes, straightforward scheduling, experience with residential exterior cleaning, and proof that the company is properly insured.
- Clear information about what the quote includes
- Cleaning methods appropriate for the surfaces around the property
- Insurance coverage for work performed around the home
- Service guarantees or other commitments that show the company stands behind the work
CleanPro also offers an 18-month mold-free guarantee. Choosing a residential power washing company involves more than comparing the lowest price.
Is power washing the same as pressure washing?
The terms are often used interchangeably, but there is a technical difference. Power washing commonly refers to pressurized water that may be heated, while pressure washing typically uses pressurized water without added heat.
For residential cleaning, the exact equipment, pressure level, temperature, and cleaning solution matter more than the label alone. CleanPro’s pressure washing services are matched to the surface and the type of buildup being removed.
How long does residential power washing take in St. Louis?
The time depends on the size of the job, the surfaces being cleaned, and how much buildup needs to be removed. In general:
- Smaller concrete or exterior cleaning jobs may take an hour or two.
- Decks, patios, and several outdoor features may take a few hours.
- Whole-property or mixed-surface jobs may take much of the day.
Total power washing time also changes with access, surface condition, and the cleaning method required.
