Yes — soft washing is actually the recommended method for pavers and natural stone. High-pressure washing can dislodge paver joints, strip sealant, and etch the surface of natural stone, causing damage that's costly to repair. Soft washing uses gentle, low-pressure water paired with specialized cleaning solutions that break down moss, algae, and organic staining at the source without disturbing the surface. At Dowers Power Wash LLC, our soft washing technique effectively cleans all paver and stone surfaces without voiding manufacturer warranties or causing structural damage common with DIY pressure washing attempts.

Absolutely. Moss removal from concrete requires the right balance of cleaning solution strength and pressure settings. Too much pressure can pit or etch the concrete surface, while the wrong cleaning agents can leave residue or cause discoloration. Our team uses professional-grade, eco-friendly moss removal solutions specifically formulated for concrete surfaces, applied at appropriate pressure levels to lift and eliminate moss without harming the concrete. Our solutions also continue working after the job is done, slowing the return of organic growth.

For most Olympia area homeowners, we recommend professional patio cleaning every one to two years. However, the right frequency depends on several factors specific to your property — including how much shade your patio receives, proximity to trees, surface material, and drainage. Patios in heavily shaded or tree-lined yards, which are common throughout Olympia's neighborhoods, tend to accumulate moss and algae significantly faster and may benefit from annual cleaning. During your free estimate, our team will assess your patio's condition and recommend a maintenance schedule that makes sense for your specific situation.

It can — if done incorrectly. High-pressure washing directed at paver joints can dislodge the sand or grout that holds them in place, leading to uneven surfaces and long-term instability. That's why Dowers Power Wash LLC uses surface-appropriate pressure settings and techniques for every job. For jointed paver surfaces, we use softer washing methods that clean thoroughly without disturbing the joints. If we identify any existing joint erosion or damage during our assessment, we'll flag it so you can address it before it becomes a larger problem.

Yes — moss on a patio is both a safety hazard and a long-term surface threat. Moss creates an extremely slippery surface when wet, which is a serious concern in Olympia's rainy climate where patios stay damp for much of the fall and winter. Beyond the slip risk, moss holds moisture against your patio surface, accelerating deterioration, loosening paver joints, and breaking down grout and sealants over time. Removing moss promptly and applying a preventative treatment is the most effective way to protect your patio and keep your outdoor space safe year-round.

You can, but there are real risks to DIY patio cleaning that often lead to more problems than they solve. Consumer-grade pressure washers frequently deliver inconsistent pressure that can damage pavers, etch concrete, strip sealant, or dislodge grout. DIY cleaning solutions also tend to address surface-level growth without killing the roots, meaning moss and algae return much faster than with professional treatment. Without the right equipment and technique, it's easy to cause damage that costs far more to repair than a professional cleaning would have. Dowers Power Wash LLC brings professional-grade equipment, surface-specific expertise, and eco-friendly solutions that deliver lasting results safely — without the risk.
