Siding & House Washing in Kirkland
Many of the ramblers and split-levels in Rose Hill, Kingsgate, and Juanita have been standing since the 1960s and '70s, often on wooded lots. The wall that faces north or sits next to the trees is usually where the green shows up first.
The north wall turns green and stays that way
Painted siding that never sees direct sun stays damp from fall to spring, and algae settles into the paint's surface. On older Kirkland homes with a few coats of paint already on them, that film holds moisture against boards that have less margin left.
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.
One color of siding again, all the way around
The shady wall matches the sunny ones again, and the paint isn't spending another winter under a wet green film, so the next repaint can wait until it's actually due.
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
- Pre-rinse & pre-treat. A gentle detergent breaks down algae and mold before any pressure touches the siding.
- Soft wash. Dirt and growth lift off at low pressure, without forcing water behind panels or trim.
- Full-house rinse. Every wall is rinsed clean, with care around windows, outlets, and landscaping.
- 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
We're planning to sell. Is house washing worth it before listing?
It's one of the quicker ways to make a house look cared for in listing photos, especially when one wall has gone green. Text us your listing date and we'll aim to finish before the photographer comes.
Will you need to get into our backyard?
Usually, yes, since the shady back wall is often the one that needs it most. If you have a locked gate or a dog, let us know when you text for a quote and we'll plan around it.
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.
