Pressure washing in Dallas

Pavement wash water may go into the street or a storm drain only if it has no soaps or chemicals, is clean enough not to harm the receiving stream, and causes no erosion or muddy runoff. That applies to driveways, sidewalks, parking lots and building walls.

• Washing with chemicals: the city tells washers to block the storm drains and collect all contaminated water by wet vacuum or a similar method.
• Washing with water only: block the drains and divert the water onto landscaping or grass.

Ask the company which method it uses on your job and whether it brings drain covers and a recovery vacuum. A crew that plans to use degreaser on an oil-stained driveway and let it run to the gutter is putting the violation at your curb. Dallas Stormwater Management takes questions at 214-948-4022.

Pressure washing questions to ask in Dallas

• Will you use any soap, detergent or degreaser, and if so, how will you recover the water?
• Do you bring storm drain covers or filter socks for water-only washing?
• Where does recovered water go when the job is done?
• Is sales tax included in the quote, and do you hold a Texas sales tax permit?

HomeGuide's national figures are the guide here. Washing a house runs $170 to $360, most often about $265 (April 2024). A standard two-car driveway costs $100 to $350, usually around $200, and many companies charge a minimum of $75 to $150 even for small jobs (June 2026). Sealing a driveway afterward adds $100 to $300. Renting a machine yourself costs $40 to $100 a day.

Texas taxes pressure washing of buildings, sidewalks and parking lots as building or grounds cleaning, residential or not, and a company doing it must hold a sales tax permit and collect tax. Expect tax on top of any quote. The Texas pressure washing guide has the full price picture.

Runoff shapes a Dallas pressure washing job. Sending water-only rinse onto a lawn is the city's own suggestion, and muddy water running down the gutter isn't allowed, so bare beds next to a driveway may need covering. Pair the job with gutter and roof checks from Dallas roofers if the house is due for both.
