The Ranking
Our top 5 pressure washing companies in San Antonio
San Antonio is hard on the outside of a house. Long, humid summers feed mildew and green algae on shaded north walls, stucco and roof tiles, and live oak pollen coats driveways, patios and screens every spring. Limestone dust from construction and caliche roads settles on everything, and older homes in neighborhoods like Alamo Heights and Monte Vista have painted wood and brick that will not take high pressure.
That is why most good crews here split the work. Soft washing uses low pressure and a cleaning solution to kill mildew and algae on siding, stucco and roofs, then rinses it off. Pressure washing, with a surface cleaner and more force, is for concrete driveways, walks and pool decks. A crew that blasts stucco or tile at full pressure can etch the finish, force water behind siding or crack tiles, so ask which method each surface will get.
Water rules matter too. The San Antonio Water System treats runoff from washing that reaches a gutter, ditch or storm drain as water waste, and city rules bar wash water from going into the storm sewer. SAWS requires anyone who power washes for pay to register with it and to collect wash water or send it to the sanitary sewer. During drought stages, SAWS limits washing of driveways, sidewalks and other hard surfaces, so check the current stage before you book a flatwork cleaning.
Texas has no state licence for pressure washing, so the check falls on you. Ask for a certificate of general liability insurance, ask whether the crew carries workers' compensation, which Texas does not require, and ask for the company's SAWS power washing registration. A written quote should name each surface and the method used on it.
We set out to find ten companies but only five passed every check. Most San Antonio washing outfits run from homes or have no street address on Google, and several others listed coworking suites, mailbox numbers or addresses in Boerne, Bulverde and other nearby towns.
