House washing in Metairie, Louisiana lifts green algae, pollen and mildew from vinyl, wood and painted siding on homes that sit close together and shade each other. 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.
Metairie is a dense residential area with small lots, and the close spacing is what puts the most growth on the siding. Homes shade each other, so the walls between buildings stay damp and grow algae and mildew faster than an open property would. 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. The siding that faces a neighboring wall is treated with the same care as the broad fields, because it stays wet longer and the growth there is heavier. Pollen settles across every face through the spring and adds to the film. The work does not include roof cleaning, deck restoration, or repairs to damaged siding, and it does not seal the surface. What any single home needs depends on how close the next building sits 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 walls that stay shaded between buildings 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 close spacing here means the walls between buildings stay shaded and damp, which is exactly what algae and mildew need. A wash lifts that growth, and the walk-through shows which walls are worst. Homes that sit tighter together usually need the work sooner than ones with more open sides.
Yes. The gentle rinse is matched to the surface, so the finish is not cut and water is not driven behind the walls. The walk-through sets the right approach for those tighter walls, and the crew works so sediment sheets off rather than drying in streaks.
Most homes here benefit from house washing once a year, and the walls that stay shaded between buildings 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.
