House washing in Kenner, Louisiana lifts green algae, pollen and organic streaks from vinyl, wood and painted siding on homes that sit on flat lots where water stands after rain. A gentle rinse matched to each surface clears the growth without forcing water behind the walls, so the exterior reads clean through the humid season.
Kenner is a mix of residential blocks and commercial corridors on flat ground, and that flat grade is what puts the most growth on the siding. Water that stands after rain keeps the lower walls and the shaded sides damp, so algae and mildew hold there longer than on a sloped lot. House washing covers vinyl, wood and painted siding, the trim, the window frames, the soffits and the fascia boards reachable from the ground. The dark streaks that run under the roof edges from gutter overflow lift with the rinse, and the exterior gutter faces are wiped as part of the work. Siding near a busy road collects a gray film of dust and exhaust that lifts with the rinse. Painted trim is treated with the same care as the broad siding fields, because the finish there is thinner and cuts more easily. The work does not include roof cleaning, deck restoration, or repairs to damaged siding. What any single home needs depends on how water moves across the lot and how long the growth has been left, and a walk-through settles the scope before any price is set.

The job starts with a walk around the home to read what is growing on each wall and where the worst streaks sit. The siding material and the sides that stay damp on the flat grade are noted, then a straightforward price is given before anything gets wet.
Delicate areas are masked or routed away from, and a gentle rinse is applied to the siding, trim and soffits. The crew works from the top down so sediment moves off the walls rather than back onto clean sections below.

Every wall gets a final rinse and a walk-through. Anything missed is handled before the crew leaves, and the work area is left clear of debris and equipment.
The flat grade here lets water stand after rain, so the lower walls and the sides that stay shaded hold moisture longer than on a sloped lot. That damp is what algae and mildew feed on. A wash lifts the growth, and the walk-through shows which walls are worst and whether they need the work sooner.
Yes. Siding that faces a busy road collects a gray film of dust and exhaust on top of the algae, and the gentle rinse lifts both. The method is matched to the surface, so the finish is not cut, and the walk-through sets the right approach for those walls.
Most homes here benefit from house washing once a year, and sides that stay damp on the flat grade may need it sooner. A walk-through shows whether the growth is at that point or whether it can wait. There is no fixed schedule.
