Soft washing that kills it, not just moves it.
Siding, stucco, and painted brick cleaned at low pressure with the solution doing the work — so the mildew doesn't come back in six weeks.
It's alive, and it lives in the north side
The grey-green film creeping up the shaded side of a Houston house isn't dirt. It's algae, mildew, and lichen — living organisms feeding on moisture that never fully dries out between rains.
That's why the north and east elevations always look worse than the front, why it comes back faster every year, and why rinsing it off with a hose is a temporary fix at best. The visible growth is the top of a root structure that's already into the surface.
Pressure alone removes what you can see and leaves what you can't. Worse, on stucco and painted brick, enough pressure to strip organic growth is also enough pressure to strip the finish.

- —Dark runs below gutter seams and downspouts
- —Mildew in the mortar of painted or unpainted brick
Low pressure. Real chemistry. Full rinse.
Soft washing applies a professional cleaning solution at roughly garden-hose pressure, lets it dwell long enough to kill the growth at the root, then rinses the whole elevation clean. It's the method siding and stucco manufacturers actually recommend.
- 01 Pre-wet. Plants, beds, and turf saturated before anything is applied.
- 02 Apply. Solution laid on from the bottom up so nothing streaks ahead of the wash.
- 03 Dwell. Time on the wall is what kills the growth. Rushing this is why it comes back.
- 04 Rinse. Top down, wall by wall, including windows and beds underneath.

A brighter, more even brick exterior.
Low-pressure treatment lifted the organic buildup while protecting the brick, mortar, windows, and landscaping.
This is algae—not ordinary dirt.
Green algae thrives on shaded siding that stays damp. A proper soft wash treats the organic growth at low pressure, then rinses the siding clean without blasting water behind the panels.

What we soft wash
If it has a coating, a texture, or a seam that water can get behind, it gets soft washed — not pressure washed.
- —Hardie and fiber cement siding
- —Stucco, including EIFS
- —Painted and unpainted brick
- —Vinyl and wood siding
- —Soffits, fascia, and eaves
- —Columns, trim, and shutters
What we protect while we do it
- —Landscaping pre-wet before and rinsed after
- —Exterior outlets, fixtures, and cameras covered
- —Doors, weep holes, and vents kept clear of direct spray
- —Vehicles and patio furniture moved or covered
What actually changes
- 01 The house reads its real color again. Most homeowners are surprised how much lighter the paint or brick was underneath.
- 02 Growth stays gone longer. Killing it at the root buys months over rinsing it off.
- 03 Paint and caulk last longer. Organic growth holds moisture against the surface. Removing it slows what that moisture does.
- 04 It photographs. If you're listing, a house wash is the cheapest exterior change that shows up in every listing photo.
Do it in the right order
House washing goes first. Everything the wash rinses down onto gets cleaned after — which is why we like to bundle it.
Window Cleaning
Wash first, glass second. Otherwise the windows get dirty twice and cleaned twice.
After the washConcrete Cleaning
Whatever comes off the walls lands on the drive. It's the natural second half of the visit.
Same visitGutter Cleaning
The dark runs under the gutter line usually mean the gutters are part of the problem.
Houses we wash
Brick, stucco, and Hardie are the three dominant exteriors across our service area — all three soft wash.
Older Bellaire and Meyerland homes with painted brick are the most common call. Newer builds in West U and Memorial are usually Hardie and stucco.
