House Power Washing

What House Power Washing Actually Includes

A proper house power washing job is not just "point a wand and rinse." Real pros pre-inspect the surface, protect landscaping and adjacent finishes, apply the right cleaning chemistry at the right dwell time, then rinse at pressure appropriate to the substrate. Skipping any of those steps is how you end up with etched concrete, oxidized siding, or shingles missing granules. We use the same process on every property whether it's a $300 driveway or a $6,000 multi-building commercial route.

Pressure Washing vs. Soft Washing — Which You Need

The single most important choice on any exterior job is water pressure. Concrete, brick pavers, and unpainted masonry tolerate 2,000+ PSI through a surface cleaner. Siding, stucco, painted surfaces, and roofs need soft washing — under 500 PSI with a sodium-hypochlorite blend that kills the biofilm at the source. Using pressure on the wrong surface is the #1 cause of exterior damage; it's also why cheap outfits leave you with problems six months later.

Real Pricing You Can Expect

For house power washing, most residential jobs fall between $179 and $899 depending on square footage, access, and how much biological growth has taken hold. Driveways are typically $179–$429. A single-story house wash is $279–$549. Two-story homes with attached driveway packages run $499–$899. Roof soft-wash adds $349–$799. Commercial and multi-tenant work is quoted flat after a walkaround. We never charge by the hour — that incentivizes going slow, which is not what you want.

What Drives the Price Up

• Heavy algae or gloeocapsa magma requiring a stronger soft-wash mix and longer dwell time
• Two- and three-story elevations that require extended reach and safety setup
• Rust removal or oxidation stains on concrete (specialty chemistry, more labor)
• Post-storm mud, tree sap, or bird debris that must be pre-treated
• Historic finishes, delicate coatings, or delicate landscaping requiring extra protection

How to Vet the Right Company

Ask three questions before you book anyone for house power washing: (1) Are you licensed and insured — can I see a certificate of insurance? (2) Do you use hot-water surface cleaners on flatwork and soft-wash chemistry on siding and roofs? (3) Do you guarantee your work in writing? A professional outfit answers yes to all three without hesitation. If the answer is vague or the price seems too low, the shortcuts are being taken somewhere — usually on chemistry, insurance, or the tech's training.

How Long the Result Should Last

A properly executed house power washing clean should hold up for 12 to 24 months depending on climate and surroundings. Homes in the humid Southeast tend to sit at the 12-month mark; drier climates and open lots stretch to 18–24. If you're seeing biological growth return in under 6 months, the previous job used pressure alone without soft-wash chemistry — the growth was never actually killed at the source, just physically knocked back.

When to Schedule

Most homeowners get the best results scheduling in late spring after pollen season, or early fall before winter closes in. Mid-week appointments (Tuesday–Thursday) are usually easier to book and often route more efficiently, which keeps the quote tighter. Peak weekends in spring and late summer book 2–3 weeks out — plan accordingly, especially for pre-listing washes or event prep.

Bottom Line

House Power Washing is one of the highest-ROI exterior maintenance projects a property owner can commission. Done right, it protects paint, extends roof life, and adds real curb appeal at a fraction of the cost of repainting or resealing. Done wrong, it damages the exact surfaces you're trying to protect. Hire a licensed, insured crew that knows the difference between pressure and chemistry — and don't chase the cheapest quote.
