Pressure Washing in St. George, Utah
Pressure washing services in St. George — driveways, walls and roofs, and why hard water and delicate desert surfaces need a careful operator.
Dust, hard water and sun
Three things make surfaces here dirty in specific ways. Fine wind-blown dust settles on everything continuously. The water is mineral-heavy — the City of St. George's 2025 Drinking Water Quality Report records total dissolved solids of 118 to 936 ppm from city groundwater sources — so sprinkler overspray leaves persistent white mineral staining on walls, windows, fencing and hardscape. And intense sun bakes both onto the surface over time.
Mineral staining in particular is not simple dirt, and pressure alone often will not shift it. It responds better to appropriate chemistry than to force, which is a useful test of whether an operator knows the local conditions: someone who proposes only to turn the pressure up may cause damage without solving the problem.
Pressure is not always the answer
The most common damage in this category comes from too much pressure on the wrong surface. Stucco is widespread on houses in this region and is easily damaged. Soft stone, mortar joints, older concrete, painted surfaces, window seals and wood all have limits. Roofs should generally never be pressure washed — the correct approach for a roof is a low-pressure soft wash, and anyone proposing to blast an asphalt shingle roof is proposing to shorten its life considerably.
Ask an operator what pressure and what method they intend to use on each surface, and whether they soft wash. A good answer distinguishes between surfaces rather than treating the property as one job.
Practical points
- Ask about water source and volume. Pressure washing uses a lot of water, and in this region that is worth a conversation.
- Ask what is done about runoff, particularly where chemicals are used near planting.
- Confirm insurance. Damage from over-pressuring is the most common claim in this trade.
- Establish what is included — is a driveway priced separately from walls and walkways?

Frequently asked questions
What causes the white staining on my walls and windows?
Mineral deposits, usually from sprinkler overspray. The water in this area carries a substantial mineral load — the city's 2025 water quality report lists total dissolved solids of 118 to 936 ppm from its groundwater sources — and when that water dries on a wall, window or fence, the minerals stay behind. Over time the deposits bond to the surface. Pressure alone often will not remove them; appropriate cleaning chemistry generally works better, and adjusting the sprinklers so they stop hitting the surface prevents recurrence.
Can pressure washing damage my house?
Yes, and over-pressuring is the most common problem in this trade. Stucco, which is widespread on houses in this region, is easily damaged, as are soft stone, mortar joints, older concrete, painted surfaces and window seals. Roofs are a particular concern: asphalt shingles should not be pressure washed at all, since it strips the protective granules and shortens the roof's life. Ask what pressure and method an operator intends to use on each surface, and whether they offer soft washing.
How often should I have exterior surfaces cleaned here?
It depends more on exposure than on a calendar. Surfaces that catch sprinkler overspray develop mineral staining relatively quickly and benefit from more frequent attention, as do north-facing surfaces where anything organic can persist. Driveways and walkways accumulate dust and vehicle residue steadily. Many households here find an annual clean adequate for general appearance, with targeted work where staining is worst. Fixing the underlying cause — usually irrigation aimed at the house — reduces the frequency substantially.
