Patio cleaning

Patios are made for relaxing, gathering, and enjoying the outdoors — but over time, they collect grime, moss, and stains that can make them slippery, unsightly, and hard to enjoy. Whether your patio is poured concrete, brick, pavers, or natural stone, we clean it using the right pressure and technique for the surface type and condition. Our cleaning restores your patio’s original look without dislodging pavers or damaging grout lines.

At Snohomish Pressure Washing, we clean patios with a careful, surface-specific approach that protects your hardscape while delivering powerful results. Whether you’re getting ready for summer, planning a gathering, or just want a space that feels fresh again, we’re here to help.

Bigfoot-tough cleaning. Small town service.

Why clean your patio?

Your patio takes a beating from the weather and foot traffic year-round. Cleaning improves how it looks, how safe it is, and how long it lasts.

Improve safety
Slippery surfaces caused by moss, algae, or mildew are a common hazard — especially in shaded areas or near water.

Restore the surface’s color and texture
Dirt and organic buildup dull natural color and beauty. A good cleaning brings out the original look of stone, pavers, or concrete.

Protect against long-term damage
Buildup holds moisture that can lead to staining, surface breakdown, and even freeze-thaw cracking during colder months.

Risks of not cleaning your patio

You might not notice the grime building up day to day — but your patio does. And over time, a little neglect can turn into a bigger (and slipperier) problem.

  • Surfaces become slippery and hazardous, especially in rainy conditions
  • Moss, mildew, and algae cause staining and accelerate material wear
  • Organic buildup can lead to water retention and surface cracking
  • Neglect reduces the life and appearance of your outdoor living space

Sometimes, but we always use them responsibly. For tougher buildup, we may apply eco-friendly, biodegradable cleaners to loosen dirt and organic material. We rinse thoroughly and avoid harsh chemicals that could harm nearby landscaping or runoff into drains.
Yes, we specialize in removing organic growth like moss, algae, and mildew. These are especially common in shaded or damp patio areas. Our cleaning process lifts buildup while also helping prevent early regrowth by removing the spores at the source.
Most patios benefit from cleaning once per year, especially in damp climates like Snohomish County. If your patio is shaded, heavily used, or prone to moss growth, more frequent cleanings may be needed to keep it safe and looking its best.
Yes. Once the patio is dry, it’s safe for kids and pets to return. We use pet-safe, plant-friendly cleaning products and rinse everything thoroughly. If we use any spot treatments or stronger solutions, we’ll let you know if extra drying time is needed.
Yes, we also clean steps, sitting walls, retaining walls, and vertical stone or concrete features around your patio. These areas collect just as much grime as the flat surfaces and deserve the same level of care and attention.
