Executive Summary: House Washing Houston
House washing in Houston removes dirt, mildew and algae from siding, stucco, brick and trim, using low-pressure soft washing on anything painted.
The work is prep-only: soft wash, rinse and plant protection. Most homes take an estimated 2 to 6 hours with 1 to 3 technicians. Typical Houston-area pricing is $400 to $600 for a 1,500 to 2,000 sq ft home, up to $1,600 for larger homes (estimates).
Weather can delay a wash, and siding and painted surfaces always get soft washing, not high pressure. Washing is not mold remediation.

Stop Letting Fading & Damage Hurt Your Property Value
Mildew and algae on shaded walls
Houston humidity grows mildew on north walls and under eaves. A soft wash with a cleaning solution removes it without forcing water into the walls.
High pressure on the wrong surface
Too much pressure strips paint, etches stucco and pushes water behind siding. We keep higher pressure for brick and concrete only.
Dirty walls before a repaint
Paint will not stick to dirt or chalk. Washing comes first; see Exterior Painting Houston TX.

House washing usually requires an estimated 2 to 6 hours for most Houston homes, depending on size, stories and how much mildew is on the walls. Plants get wet down before and after, and windows get a final rinse. Two-story homes and heavy mildew sit at the long end.
The driveway can be cleaned the same day; see Driveway Cleaning Services.
Yes, we do, and it is the first step of every exterior repaint. Washing removes dirt, chalk and mildew so primer and paint bond, and the surface then dries at least a day before any scraping or priming. Concrete gets washed and dried before coatings too.
