Pressure Washing Deming, WA

The frequency of deck, path, and driveway cleanings depends on things such as whether it is shaded or in a sunny spot, how much mileage is seen on said surface, as well as the type materials used. For most properties, pressure washing should be done once every year depending on your desired look.

The main difference between cleaning a wooden deck versus a concrete surface like a driveway comes down to equipment. We don’t use high-powered machinery on wood — this is to protect the deck’s grain. Instead of the pressure washers we use on harder surfaces, we apply a mixture of soap, water, and hypochlorite, then scrub with a long-handled brush to remove dirt and debris.

No, pressure washing alone doesn’t permanently eliminate algae and moss. These organisms leave behind spores that survive even aggressive cleaning, so regrowth is inevitable over time — especially in shaded or damp areas.
The hypochlorite-based solution we use is more effective in this regard. The bleach kills the algae and moss at a biological level rather than just removing the visible growth, which significantly slows regrowth. That said, periodic reapplication is still recommended as part of a regular maintenance routine.

The main ways to prevent damage while pressure washing are using a surface cleaner to evenly distribute pressure across a wider area, selecting the right nozzle — a wider fan tip like 25 to 40 degrees rather than a zero-degree tip — and always keeping the pressure setting appropriate for the material being cleaned.

That depends on a few factors — the size of the area, the type of surface, and the level of buildup. A standard driveway or patio can typically be done in a couple of hours, while a larger property or heavily soiled surface will naturally take longer. We always assess the job beforehand so we can give an accurate time estimate.
