Pressure washing costs in Dallas-Fort Worth

Summer at the Dallas-Fort Worth airport is mostly 90-degree days. NOAA's 1991 to 2020 normals count about 79 of them from June through August, out of 92 days, and about 106 over a whole year.

That heat changes how a house wash goes. On a hot wall, a soft-wash cleaner can dry before anyone rinses it, and dried cleaner can streak siding and spot glass. A careful crew works the shady side first, in short sections, and keeps the wall wet until the rinse.

Spring is the easier season here. The same normals put only about 8 days at 90 degrees or more from March through May, against about 20 from September through November. Cooler walls give a crew more time before the cleaner dries, which makes spring a kinder season than fall for a full-house wash.

Who's holding the wand matters in Fort Worth. Anyone who does mobile power washing for pay there needs a city permit, a program the city says exists to keep detergents and other pollutants out of its storm drains. Permitted crews can't let wash water leave the property, and they're told to soak up puddles of oil or grease with absorbent clay before they wash. Every truck and trailer that carries a rig has to be registered and show its number on both sides, in figures at least 3 inches tall. Those numbers and the city's sticker are what Fort Worth inspectors look for on a job, and you can read them from your own driveway.
