What It Costs to Power Wash a House in Frontenac: A Breakdown by Surface

What National Cost Guides Say House Washing Costs

As a reference point before you compare quotes: national cost guides put house washing at roughly $0.15 to $0.75 per square foot, with most fixed-price residential jobs quoted between $150 and $500 and the average landing around $250 to $400. A typical whole-house wash is commonly quoted between $300 and $600, and most contractors carry a minimum charge, usually $100 to $150, to cover drive time and setup on a small job.

Other surfaces are quoted separately, and commonly land around $200 to $475 for a driveway and $200 to $480 for a patio.

Those are national aggregates, not our price, and they are wide for a reason. The same house sits at the bottom of the range in vinyl on one story and near the top in stucco on two with restricted access. Use them to sanity-check a bid; use an actual estimate to get your number.

Cost to Power Wash a House: Siding Is Priced by Material, Not Just Size

Siding is measured by wall area and number of stories, but the material decides the method, and the method decides the labor. Vinyl and painted lap siding are washed at low pressure with the cleaning solution doing the work. Stucco, EIFS, brick with soft mortar joints and stained cedar need lower pressure still, and much more careful rinse control.

Second stories cost more than first stories because reach costs more than area — an extension wand, a taller ladder set, or in some cases staging.

Driveway and Concrete Restoration Is Priced by Condition

Flatwork is the one surface where area really is most of the number, but condition is the multiplier. General dirt and algae come off in a single surface-cleaner pass. Oil, rust, tannin staining from leaves and tire marks are separate treatments applied before that pass.

Sealed and stamped concrete is its own line. It cannot be cleaned as aggressively as broom-finished concrete without damaging the seal, and resealing afterward is a separate decision rather than an assumed part of the wash.

Pool Decks Cost More Per Square Foot Than Driveways

A pool deck is usually smaller than a driveway and usually costs more per foot. The surfaces around a pool tend to be textured — cool-deck coating, exposed aggregate, travertine, pavers — and texture holds growth and takes longer to clean without stripping the surface.

There is also containment. Runoff cannot go into the pool, and equipment, coping and surrounding plantings all have to be protected before the work starts.

Deck and Fence Care Is a Different Job Than Washing

Wood is the one surface where washing is usually the first half of a two-part job. Cleaning a deck or fence raises the grain and opens the wood, which is exactly what you want before a stain or sealer, and exactly what you do not want if nothing goes on afterward.

So a deck wash quoted on its own and a deck wash quoted as prep for staining are different numbers with different follow-up. It is worth being clear which one you are asking for.

Why a Single Low Number for Everything Is Worth a Second Look

The most common bad quote in this category is a flat bundle — one round number for the house, the driveway and everything else, offered at the door. It is not always wrong, but it is a number set before anyone measured anything.

The specific risk is pressure. A bundle price only works if every surface is done fast, and fast means high pressure. That is how stucco takes on water, how soft mortar joints get opened, and how concrete ends up with faint overlapping arcs etched into it that never wash out.

A quote broken out by surface is easier to compare, easier to trim back, and much harder to hide a shortcut inside.

What Is Actually Covered

We are licensed and insured with $2M coverage, and the crew on your property is our own — no subcontractors.

Each surface is quoted separately against a defined scope and the condition we found it in, so you can take the whole property or just the driveway. If conditions differ once we are on site, you hear the revised number before the work happens.
