Pressure Washing Driveway Cost Calculator

Professional driveway pressure washing typically costs $0.20 to $0.40 per square foot, so a standard 2-car driveway of 500–600 sq ft usually runs $150 to $250 — about $180 in this calculator's default for a 600 sq ft concrete driveway. Most jobs carry a minimum charge (around $150) because it's not worth a crew's time to set up for a tiny area. The surface type (asphalt is cheapest, pavers cost most for re-sanding), the condition (heavy oil, mold, or moss adds a per-foot surcharge), and add-ons — sealing, oil or rust treatment, or adding a sidewalk — move the total. Enter your driveway size, surface, and condition above for a localized estimate.

Standard pressure washing lifts surface grime and lightens light oil, but it often won't fully remove deep, set-in oil stains on its own — the oil has soaked into the concrete's pores. Removing significant oil requires a degreaser or a dedicated oil-spot treatment applied and dwelled before washing, which is why it's billed as a separate add-on (about $75 here). The same goes for rust, which needs an acid-based treatment ($60 add-on). If your driveway has obvious oil or rust staining, plan for the treatment rather than expecting a plain wash to erase it — and know that very old, deep stains may lighten rather than vanish completely.

Asphalt needs a gentler touch than concrete. Full high pressure can blast away the fine aggregate and surface binder, leaving the asphalt rough or pitted. Professionals use a lower-pressure 'soft wash' technique — often with cleaning solution and a surface cleaner attachment rather than a concentrated wand — to lift dirt, algae, and stains without stripping the surface. That's why asphalt is priced slightly lower per foot than concrete in this calculator: it's actually cleaned at lower pressure. If you're DIY-ing, keep the tip well back and moving; getting too close to asphalt is the most common way to damage a driveway.

Sealing is highly recommended for concrete and pavers, and washing first is what makes it work — sealer bonds properly only to a clean, dry surface. A quality sealer protects against water penetration, oil and stain absorption, freeze-thaw damage, and UV fading, and it makes future cleaning easier. It adds about $0.50 per square foot here and is best done as part of the same project since the driveway is already clean, though it requires the surface to fully dry first (often a return visit). Asphalt is 'sealcoated' rather than sealed with a clear sealer, on a different schedule. For most concrete and paver driveways, washing plus periodic sealing is the combination that keeps them looking new and lasting longer.

Most driveways benefit from a pressure wash about once a year to remove built-up dirt, tire marks, algae, and the grime that dulls the surface. Shaded, damp areas prone to moss, mold, or algae growth may need cleaning every six months, since organic growth returns faster and can make the surface slippery. Climate matters: humid regions and north-facing driveways under trees green up quickly, while sunny, dry areas can go longer. Regular cleaning isn't just cosmetic — removing algae and moss reduces slip hazards, and clearing oil and organic buildup before it sets makes each wash easier and helps sealer last. Pair the annual wash with re-sealing every few years for the best protection.

Yes, if it's done incorrectly. Too much pressure, or a tip held too close, blasts the joint sand out from between pavers, which can leave them loose and prone to shifting or weed growth. Done right, pavers are washed at controlled pressure and the joints are re-sanded afterward with polymeric or jointing sand to lock everything back in place — which is why paver driveways are priced highest per foot in this calculator (the re-sanding is part of the job). If your pavers have shifted or grown weeds, a proper wash-and-re-sand restores both the look and the stability. Skipping the re-sanding after a wash is the most common mistake and leaves the pavers worse off than before.

Usually the base quote covers the driveway only. Sidewalks, walkways, curbs, and paths are typically added for an extra fee based on their area — this calculator includes an 'add sidewalk/walkway' option (about $50) since the crew is already on-site with equipment set up. Because most of the cost of a small job is mobilization and setup, bundling the connected concrete — the front walk, a path to the backyard, or the garage apron — into the same visit is far cheaper than booking it separately later. If you want more than the driveway cleaned, mention it up front so the whole area is quoted together and you're not paying a second trip charge.

The core difference is heat. Pressure washing uses unheated water at high pressure and relies mainly on mechanical force to blast away dirt. Power washing uses heated water, which breaks down grease, gum, oil, and stubborn grime far more effectively — the heat does chemical work the pressure alone can't. For a typical residential driveway, standard pressure washing (often with a cleaning solution and a flat surface cleaner) is plenty. Power washing shines on heavy grease, oil, chewing gum, or commercial surfaces. In practice many companies use the terms interchangeably and adjust pressure, heat, and detergent to the surface and stains, so it's more useful to describe your driveway's condition than to ask for one term specifically.
