Exterior cleaning in Bothell, WA

Less moss, but more of everything else

The tradeoff for open subdivisions is hard surface. Bothell homes have big driveways, wide walkways, patios, and often a second parking pad — considerably more concrete per house than an older Everett lot. Concrete in this climate greys and grows algae in the expansion joints regardless of how much sun the roof gets.

Newer neighbourhoods also mean composite decking rather than cedar, which is its own category. Composite will not rot, but the textured surface grows mildew in its grain readily — often more visibly than real wood — and it must not be pressure washed, because composite scars permanently under pressure.

Roofs still need attention, just less often. A well-exposed Bothell roof can often go three to four years between cleanings where a shaded Shoreline one wants two.

Fiber cement, vinyl and the joints in between

Fiber cement — HardiePlank and similar — is the dominant siding on newer Bothell homes and is genuinely durable. Its face handles washing well; its vulnerability is the cut ends and joints, which is where water gets in. We work those carefully rather than treating the wall as one uniform surface.

Modern vinyl is forgiving but it laps, and water driven upward under a lap has nowhere to go and no realistic chance of drying out. Low pressure, working downward, always.

The other Bothell-specific factor is HOA and community standards in the newer developments, which tend to be stricter about visible exterior condition than older neighbourhoods. It is a common reason people book here before it becomes obviously necessary.
