Siding & House Washing in Bellevue

House Exterior Soft Washing

Removed algae and grime without harming siding.

House siding with algae and grime buildup before soft washing in Kirkland, WA

In Bridle Trails, homes sit on large lots under tall evergreens, and some walls barely see the sun from October to May. Those walls are where green algae shows up first, often in a band near the ground where splashback keeps the siding wet.

Splashback and shade are growing algae along your walls' base

Rain bouncing off the ground soaks the lowest courses of siding, and on a wall shaded by tall trees, it never really dries. Algae settles into that damp band first, then works its way up the wall a little more each season.

Full-house soft washing, not high-pressure blasting

Starting at $200 We pre-treat with detergent to break down algae and mold, soft wash at low pressure to lift it without forcing water behind panels, then rinse every wall clean and check the shaded, high-buildup spots.

Walls that dry out after the rain instead of staying green

With the algae lifted off, the siding sheds water and dries between storms again, and the green band along the base stops creeping upward through next winter.

Neglected algae leads to repainting or re-siding, not a wash

Skip a season or two and that colonized siding won't just need washing — paint starts lifting and, on wood siding, rot sets into the boards themselves, turning a wash into a repaint or re-siding job.

What's included

  1. Pre-rinse & pre-treat. A gentle detergent breaks down algae and mold before any pressure touches the siding.
  2. Soft wash. Dirt and growth lift off at low pressure, without forcing water behind panels or trim.
  3. Full-house rinse. Every wall is rinsed clean, with care around windows, outlets, and landscaping.
  4. Walk-around inspection. We check the shaded, high-buildup spots — north-facing walls and under eaves — where algae collects most.

Worth knowing

Soft washing is gentle by design, but siding with existing gaps, damaged caulking, or already-peeling paint can let water in or lose more paint than usual. We'll let you know if we spot anything like that before we start.

Frequently Asked Questions

Can you wash just the shady side of the house?

Yes. If only one or two walls have gone green, text us photos of those sides and we'll quote just that part.

We're under tall evergreens. How often will the house need washing?

Homes under heavy shade usually need it more often than open lots, roughly every year or two depending on how fast the green comes back. Text us a photo and we'll give you an honest read.

What's the difference between pressure washing and soft washing my house?

Pressure washing uses high force to blast dirt off hard surfaces like concrete. Siding is more delicate — vinyl, wood, and fiber cement can crack, streak, or let water behind the panels under too much pressure. We soft wash siding instead: lower pressure, a cleaning solution that does the actual work, then a gentle rinse.

Will soft washing damage my paint or siding?

Soft washing is specifically the technique used to avoid that. High-pressure washing is what causes paint stripping and cracked siding — soft washing is the safer approach for painted or older siding.
