Patio and paver cleaning in Oregon City, matched to the surface.
Pavers, flagstone, and poured concrete all grow the same moss — but they don't take the same cleaning. We match treatment and pressure to what your patio is actually made of, so the growth dies, the joints survive, and the space is safe to walk on again before barbecue season.
Every patio and paver cleaning job is priced individually — text a photo and you’ll have an exact number before we ever show up.
Every surface gets its own approach
A poured concrete patio can take the same surface-cleaner treatment as a driveway. Interlocking pavers can't — too much pressure strips the joint sand that holds the field together. Flagstone sits in between: durable stone, fragile joints, and the occasional soft piece that will scar if you treat it like concrete. The mistake low-bid outfits make is cleaning all three the same way.
Our process starts with a pre-treatment that kills moss and algae at the root, which means the rinse can be gentler — the growth is already dead, so we're washing it away rather than blasting it off. Edges, steps, and shaded corners where the growth anchors deepest get hand attention.

Joints, sand, and keeping the moss from coming back
On a paver patio, the joints are the battleground. Moss doesn't root into the paver — it roots into the sand between them. After cleaning a badly overgrown field, the honest next step is often re-sanding: sweeping fresh joint sand (polymeric if the patio suits it) so the gaps are filled with something growth can't easily colonize. We'll tell you in the quote whether your patio needs it or can skip it.
A note on decks
Wood and composite decking are the one backyard surface we deliberately don't pressure wash like stone. High pressure furs wood grain and scars composite boards permanently. Decks get the soft-wash approach we use on siding — solution does the killing, low pressure does the rinsing. If your patio and deck connect, we'll clean both in one visit with the right method on each.
Patio and paver questions, answered.
Will cleaning blow the sand out of my paver joints?
Aggressive washing does, which is why pavers need a lighter touch than a concrete slab. We work at reduced pressure and keep the spray angle shallow to preserve as much joint sand as possible — and when some loss is unavoidable on a badly overgrown patio, we'll tell you about re-sanding before we start, not after.
What is re-sanding and do I need it?
Joint sand is what locks pavers in place and keeps weeds and moss from rooting between them. If your joints are already washed out or full of growth, the patio benefits from fresh sand after cleaning — ideally polymeric sand, which hardens and resists the next invasion. We'll flag it in your quote if your patio needs it.
Is flagstone safe to pressure wash?
With the right technique, yes. Natural stone varies — some sandstone is soft enough to scar under a tight jet. We treat first so the growth is already dying, then rinse at a pressure matched to the stone. The mortar or joint material between stones gets the gentlest handling of all.
Can you clean my wood or composite deck the same way?
Not with the same settings — wood fibers tear under concrete-level pressure and composite boards can scar. We clean decks soft-wash style, closer to how we treat siding. Mention the deck when you text and we'll quote it as its own line with the right method.
How slippery is a mossy patio, really?
It's the most common way people get hurt in their own backyard here — wet moss on smooth stone is close to frictionless. Cleaning isn't just cosmetic: killing the growth and clearing the film gives you the traction the surface was built with.
