Building exterior washing from Raincrest.

Exterior walls collect more than people realize: road dust, soot from traffic, cobwebs under the eaves, bird droppings on ledges and dark streaks where rain runs off the roofline. From the parking lot, it all adds up to a building that looks older than it is.

Raincrest washes the whole envelope or just the elevations that face the street. Crews match the pressure to the surface, using a gentler wash on painted stucco, signage and trim and more working power on bare concrete and block. Windows, doors and fixtures near the work are protected, and the wash water is rinsed down and away from entrances.

Keep exterior washing on a yearly or twice-yearly schedule so the building never slides back to gray.

Step by step

How it works.

01

Walk the building

We look at each wall, the materials and the streaks and stains you want gone.

02

Set the approach

Pressure and method are matched to stucco, block, brick, metal or siding.

03

Protect, then wash

Doors, windows and fixtures are protected before walls are washed from the top down.

04

Rinse and check

Walls are rinsed clean and the work is checked before the crew packs up.

What builds up on commercial walls.

Every wall collects something different. Street-facing stucco picks up a gray film of road dust and exhaust. Walls under rooflines and gutters grow dark vertical streaks where rain runs off. North-facing and shaded elevations hold onto a green or black film, and ledges, sills and light fixtures gather droppings, nests and cobwebs.

Knowing what is on the wall tells us how to wash it. Loose dust and cobwebs rinse away with a lighter touch, while streaks and shaded-wall film take repeated, slower passes. Every elevation is written into the quote, so you know which sides of the building are being washed and when.

Working around tenants, windows and planting beds.

Exterior washing often happens with people still nearby, so we plan it carefully. Doors, vents, light fixtures and electrical boxes near the work are protected, planting beds below the wall are rinsed, and the crew works one elevation at a time, moving cones and signs as it goes so entrances stay usable.

Office and retail buildings are washed early in the morning or on weekends, and apartment communities one building at a time with notice to residents. When the walls are done, the walkways below get a rinse. Add sidewalk and plaza cleaning so the whole frontage looks finished.

When to book exterior washing.

Good times to book are a repaint, a lease-up, a property sale or simply a building that looks tired. A wash before painting gives the painters a clean surface. A wash before a lease-up or sale makes the building look sharp in photos and tours. And for owners who just want the property to look cared for, a yearly or twice-yearly wash keeps the walls from sliding back to gray. Pair it with graffiti removal on walls that get tagged.

What does commercial building exterior washing cost?

Exterior washing is priced by the square foot of wall surface cleaned on each visit. At 2026 market rates, most building washes land between $0.17 and $0.35 a square foot, and tall, heavily streaked or delicate facades climb toward $1.00. Our commercial pressure washing cost guide shows how walls compare with lots, walkways and enclosures.

Take a two-story R&D building with about 7,500 square feet of stucco and block across its four elevations. Washed at $0.22 a square foot, one full cleaning comes to $1,650. Washed twice a year, before the rains and again in spring, that comes to $3,300 annually. Washing only the two street-facing sides cuts the visit roughly in half.

Height is the first lever: anything past what a crew can reach from the ground adds lifts and setup time. Surface matters next, since painted stucco and signage take a slower, gentler pass than bare concrete block. Heavy soot, bird droppings on ledges and dark runoff streaks under the roofline add passes. Glass, doors, light fixtures and planting beds that need protecting add prep, and night or weekend work around tenants shifts the schedule. Labor is the largest cost, so Bay Area walls price above the same work in Sacramento or Reno. An on-site walkthrough measures your walls and turns all of this into a written quote.

A few useful answers

Common questions.

Which wall surfaces can you wash?

Stucco, painted block, brick, tilt-up concrete, metal panels, siding and trim, with pressure set for each one.

Will washing harm our paint?

Painted surfaces get a gentler wash that removes dirt while leaving the finish in place.

Can you wash only the front of the building?

Yes. You can start with the street-facing elevations and add the rest later.

Do you wash wall signs and monument signs?

Yes. Signs get a gentle wash suited to their finish, so lettering and paint stay crisp.

Should we wash before repainting?

Yes. Painters get a clean wall to work on, so a wash belongs ahead of every repaint.

Can you wash covered walkways and overhangs?

Yes. Columns, soffits, overhangs and the ceilings of covered walkways are washed along with the walls.

Will exterior washing disturb our tenants?

Very little. We wash one elevation at a time, keep entrances open and schedule around the hours your tenants keep.

How often should a commercial building exterior be washed?

Once or twice a year suits most buildings, with street-facing walls and entries sometimes washed more often.
