What Is House Power Washing?
House power washing uses pressurized—often heated—water to lift heavy buildup from durable, non-painted surfaces. Think oil, rubber, salt, and baked-on grime on concrete, brick, stone, and pavers. It’s different from soft washing, which uses low pressure and detergents for paint, trim, and roofing. On most jobs, we soft-wash the house and power-wash the hardscapes so everything looks even and stays cleaner longer.
Who Power Washing Is For
Power washing helps when you’re maintaining, selling, or managing property. Here’s who gets the most value:
Homeowners: keep the place looking cared for, prep for photos or inspections, and stretch the life of paint, roofing, and hardscapes.
Property managers & HOAs: keep entries presentable and safer underfoot, manage algae in shaded areas, and follow a simple maintenance cadence.
Light commercial: restaurants, storefronts, and parking garages where curb appeal and safety both matter.

Why Hire Local St. Louis Pros for House Power Washing?
Hiring local pros prevents costly mistakes and keeps your place in good shape. Around St. Louis, heat, humidity, shade, and freeze–thaw make runoff control and a consistent finish trickier than they look. We match method to material, tune chemistry to the surface, and manage water so plants, paint, and foundations stay safe.
CleanPro uses the right method for the job. We soft wash on paint and trim; wood-safe pressure on decks and fences; pretreat and rotary clean concrete and pavers, use low-pressure washing and shingle-safe treatments for roofs. We keep water moving where it should with smart hose runs, rinses that follow the grade, and vacuum recovery on hardscapes when it matters. Landscaping is protected with pre-wet treatments, shields, and other methods to prevent damage to shrubs and turf.
You get an even clean that holds up between seasons—no damage, no streaks, no headaches.
Seasonal Patterns in St. Louis
Weather in St. Louis has a big impact on your home’s exterior. In the spring, you might be dealing with pollen films on your windows, patio furniture, and siding, plus leftover salt and winter grime on steps, porches, and walkways, and algae waking up on the north and east sides. Summer heat and humidity can accelerate that growth on shaded walls and lower courses; roof streaks may darken, and patios pick up everyday spills—sunscreen, grease, and drinks—that set into porous surfaces like concrete and pavers.
As fall hits, leaf tannins can stain concrete and pavers; you might see mud splash on lower siding and fences, and entries can get slick after rain. In winter, salt and ice-melt can mark driveways and walks, freeze–thaw can drive grime into hairline cracks, and enclosed shade may keep mildew active. We time cleanings around these patterns so results last longer.

Benefits of Home Power Washing
Exterior washing is a whole-property play, not just walls. Done right, a balanced mix of soft wash and power wash slows organic regrowth, protects finishes, restores traction on walk areas, and brings concrete and pavers back to an even read—so curb appeal holds between seasons.
- Reduce regrowth: treatments target algae/mildew at the source
- Protect finishes: shingle-safe and paint-safe methods prevent damage
- Safer underfoot: clear film and slick spots on decks, steps, and entries
- Uniform look: match color and tone across the front approach and hardscapes
Roof Cleaning
Dark trails on shingles are living growth that hold heat and moisture. Roof cleaning treats at low pressure with a shingle-safe mix so granules stay put and streaks stop feeding onto clean siding. Expect a roofline and fewer runoff trails after storms.
Fence Washing
Sun and irrigation overspray drive oxidation and algae. Fence washing resets both so coatings last longer and property edges look sharp. It also evens out color panels for cleaner sightlines from the street.
Deck Washing
Rain sets stains deeper; it doesn’t remove them. Deck washing restores traction on steps, evens traffic lanes, and preps boards so stain or sealer bonds evenly. You’ll feel the difference underfoot the next time it rains.
Driveways
The biggest slab sets your first impression. We pretreat spots, use rotary surface cleaners for an even pass, and finish with a clean rinse. Driveway cleaning lifts deep oil, leaf shadows, and rubber arcs for a uniform approach that reads well in photos.
Porches, Patios & Walkways
Porous hardscapes trap grime and grow film in shade. Porch, patio, and walkway cleaning flushes pores, treats joint growth, and protects paver sand. The result is better traction and more consistent color across the slab.
Exterior Windows
Clean siding with cloudy glass still reads tired. Exterior window cleaning is the finish pass so daylight looks crisp inside and the exterior reads clean outside. We time the rinse to follow nearby washing and cut spotting.
Frequently Asked Questions
Below are some of the most common questions we get about house power washing in St. Louis.
How often should I have my house washed?
Most homes do well with a spring reset and a fall touch-up. Add a mid-summer visit if you have heavy shade, trees, or high foot traffic on decks and patios.
What’s the difference between power washing and soft washing?
Power washing uses pressure—often with heat—for tough surfaces like concrete and brick. Soft washing uses low pressure and detergents for paint, trim, and roofing. We typically soft-wash the house itself and power-wash the hardscapes in the same visit.
Will this damage my plants, paint, or windows?
We pre-wet and shield landscaping, use low pressure on siding and trim, and rinse windows after nearby work. The process protects finishes and helps prevent spotting on the glass.
Do you pressure wash roofs?
No. We use a shingle-safe soft wash on asphalt roofs at low pressure so granules stay put. That treats streaks without shortening roof life.
Can you remove oxidation or “tiger stripes” on vinyl and gutters?
Yes. We treat oxidation and gutter streaks with the right chemistry and a gentle rinse. Spot-cleaning with high pressure causes stripes—so we avoid it.
What should I do before you arrive?
Close windows, move small items and doormats, and keep pets inside. We handle hose runs, cover sensitive electrical points, and move light furniture as needed.
How long does a typical house wash take?
Most single-family homes finish in a few hours, depending on size, access, and add-ons like roof, decks, and hardscapes.
What about runoff and environmental rules?
We manage water flow, protect storm drains, and dispose of wastewater in line with EPA guidelines. On driveways and patios, we use vacuum recovery when needed.
How do you price a house wash?
Pricing depends on size, access, and the mix of surfaces (siding, roof, decks, hardscapes). We’ll give you a clear quote up front and a simple plan for ongoing maintenance.
