House washing in New Orleans, Louisiana lifts green algae, pollen and organic streaks from vinyl, wood and painted siding on older homes where the finish calls for a gentle approach. A rinse matched to each surface clears the growth without forcing water behind the walls, so the exterior reads clean through the humid season.
New Orleans has a lot of older housing stock, and the age and the material of that stock is what shapes the wash. Siding and trim on older homes can be fragile, so the rinse is set lighter than on newer construction, and the growth lifts with the rinse and gravity rather than force. 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. Painted trim is treated with the most care, because older paint cuts and lifts more easily than newer finish. 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 the age of the siding 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 any fragile or older trim 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.
Yes, when the rinse is set for the material. Older siding and trim are washed with a lighter approach than newer construction, so the finish is not cut and water is not driven behind the walls. The walk-through is where the right setting for each wall gets settled.
It does. The heavy rain and the humidity keep algae and mildew active on shaded sides through the year, so the growth returns sooner than in a drier climate. A wash lifts what is there, and the walk-through gives an honest read on how soon the next one is likely to be needed.
Most homes here benefit from house washing once a year, and older or heavily shaded sides may need it sooner because the growth holds faster. A walk-through shows whether the siding is at that point or whether it can wait. There is no fixed schedule.
