Do You Need to Prep a Patio Before Pressure Washing?

A patio doesn't need much done to it before we show up, but the little bit of prep that does happen makes a real difference in how the final result looks — and how long it lasts. Here's what we actually check for and what you can do ahead of time if you want to get a head start.

Clear the surface

Furniture, planters, grills, toys, rugs — anything sitting on the patio needs to move before washing starts. It's not just about getting it out of the way. Anything left in place blocks water and cleaning solution from reaching that section, and you end up with an obvious clean/dirty line once everything's moved back. If you can clear the space yourself before we arrive, that saves time; if not, we're happy to move lighter items ourselves.

Sweep loose debris

Leaves, dirt, pollen, and loose grit sitting on top of the concrete or pavers should get swept off first. It's not that pressure washing can't handle it — it's that a pile of wet leaves just turns into sludge that has to be worked around, and loose grit under a pressure washer wand can act like sandpaper against the surface. A quick sweep first keeps the wash focused on what's actually embedded in the surface instead of what's sitting on top of it.

Check for oil, rust, or heavy staining

Grill drippings, motor oil, and rust spots from patio furniture are common on Pittsburgh-area patios, especially ones near a driveway or under a covered area. These usually need a dedicated pre-treatment before pressure washing, since plain water pressure alone won't lift set-in oil or rust. If you know a spot has been there a while, point it out — we'll treat it separately so it doesn't just get pushed around and re-settle somewhere else on the slab.

Protect nearby plants and surfaces

Garden beds, mulch, and delicate plantings that border the patio can be sensitive to cleaning solution runoff. We take care to rinse and dilute as we go, but if you have anything especially delicate right at the edge of the patio, a light cover or a quick relocation beforehand adds an extra layer of protection.

Know what's underneath

Sealed pavers, stamped concrete, and plain broom-finished concrete all respond differently to pressure and cleaning solution. If your patio has been sealed, stained, or recently repaired, let us know — it changes the pressure, distance, and chemical approach we use so we clean the surface without stripping a sealant or discoloring a patch.

What you don't need to do

You don't need to scrub the patio yourself, pre-rinse it with a hose, or buy a separate patio cleaner before we arrive — that's the part we handle. Prep on your end is really just clearing the space and flagging anything unusual, like a stain you've been fighting for months or a section that was patched last year.
