Pressure Washing in Thornton, CO

Pressure Washing in Thornton comes with a water question this year. City Council declared a Stage 1 drought effective March 15, 2026, after Thornton Water reported Colorado's lowest snowpack in 20 years and critically low snowpack in the Upper South Platte and Clear Creek watersheds that supply the city. The rules mostly target lawn watering, but they are a good reason to think about every gallon used outside, including the water used to clean a house or driveway.

How we keep water use low

A pressure washer pushes water through a small nozzle at high pressure, so it is designed to clean with far less running water than an open garden hose left on for an hour. We add to that by pre-treating stains so we are not rinsing one spot over and over, using rotary surface cleaners on flatwork, and shutting the flow off between sections. On siding, soft washing lets the cleaning solution do most of the work, so the rinse is short.

Thornton's water-waste rules

Thornton Water says leaks and water waste must be fixed within 10 days of a notice, and that fines for uncorrected waste start at $100 for residential customers and $250 for commercial customers, rising with repeat violations. Water running down the street for no reason is the kind of waste those rules address. We keep runoff on your property where we can and recommend checking the current drought stage with Thornton Water before booking a large outdoor cleaning.

First planned community, and everything since

Thornton began in 1953 as the first fully planned community in Adams County, with homes off Washington Street about seven miles north of Denver. By the end of 1955 it had about 5,500 residents in more than 1,200 homes. Houses from that era carry decades of weathering on brick, painted siding and concrete, while neighborhoods built much later toward the north end of the city often have stucco, stone veneer and long driveways. Each gets its own pressure range and detergent.

What we clean in Thornton

• Brick, painted lap siding and trim on older homes
• Stucco and stone veneer, soft washed at low pressure
• Concrete drives and patio slabs marked by sprinkler rust
• Wood and composite decks, fences and pergolas
• Gutters, fascia and roof soft washing

Scheduling around drought rules

Because Thornton limits lawn watering to set hours, yards may be drier than usual and plants near the house may be more stressed. We wet down and cover beds before applying any cleaner, rinse them again afterward, and avoid the hottest part of the afternoon when solutions dry fastest. If you would like the cleaning timed close to one of your two watering days, we can plan the visit that way.

Protecting the water supply downstream

Thornton stores its water in reservoirs along the South Platte River and in Standley Lake. Storm drains are built to carry rain and snowmelt, not soap and grime, so we keep rinse water away from curb inlets and keep cleaning solutions from leaving the property. Before we start, plants near the house are wet down and covered as needed, and windows and outlets are closed off.
