Why Tacoma Homes and Businesses Need Power Washing Services

OneGard, Tacoma’s local pressure washing company, has served homeowners and business owners across the South Sound for years. Rain falls on Tacoma roughly 150 days each year, and those wet months encourage moss and algae to grow on roofs, gutters and driveways. The damp climate combines with our region’s clay‑rich soils to leave red or orange residue on patios and walkways. Older neighborhoods like North End, Proctor, Hilltop and Stadium District have mature trees that shade roofs and trap moisture. In nearby areas such as Gig Harbor, Port Orchard and University Place, salty marine air adds another layer of grime.

These regional challenges mean that routine power washing is not just cosmetic; it’s preventative maintenance that protects your home’s value. Removing moss and mildew preserves vinyl siding, wood decking and shingles; flushing gutters and downspouts prevents foundation damage; cleaning patios and walkways reduces slip hazards. OneGard’s local technicians understand Tacoma’s building materials, HOAs and municipal regulations. We know which cleaning methods are safe for cedar shake roofs, vinyl siding, stamped concrete or stucco, and we follow city guidelines to ensure runoff never reaches Puget Sound.

What Power Washing Does for Your Home

Power washing (sometimes called pressure washing) uses a high‑pressure stream to blast away dirt, algae and stains from exterior surfaces. OneGard adapts the pressure and technique to each material, ensuring a deep clean without damage. Our service includes:

  • Driveway & walkway cleaning: Remove tire marks, oil stains and organic buildup from concrete, brick, pavers and asphalt. Perfect for driveways, walkways, parking lots and garages.
  • House & building washing: Safely clean siding, stucco, vinyl, brick or wood with a combination of soft‑wash detergents and controlled pressure. Our house washing removes mildew and grime, bringing back vibrant color and boosting curb appeal.
  • Roof cleaning & moss treatment: Gentle soft washing kills moss and algae on shingles, cedar shakes and metal roofs. Our process lifts dark streaks without stripping granules, and we apply treatments to delay regrowth.
  • Patio, deck & fence restoration: Wash away winter grime and mildew from wood or composite decks, patios and fences. We use low pressure on softer materials to preserve paint and stain.
  • Gutter & downspout cleaning: Flush debris, leaves and needles from gutters and scrub away the “tiger stripes” on the exterior. Clearing downspouts prevents water from overflowing and seeping into your foundation.
  • Window washing & solar panel cleaning: For a complete exterior refresh, bundle window cleaning or solar panel washing with your power washing service. Clean glass lets more light in and improves energy efficiency.

Our services are ideal for homeowners seeking to maintain property value, landlords preparing rentals for new tenants, business owners who need clean storefronts and sidewalks, and HOA boards aiming to uphold community standards. Commercial clients include retail centers, office parks, restaurants and industrial facilities. We tailor every job to the material and environment—whether it’s high‑pressure cleaning to remove oil in a parking garage or soft washing delicate vinyl siding.

Why Tacoma Homeowners Choose OneGard

Choosing a pressure washing company isn’t just about price—it’s about trust, protection, and long-term peace of mind. Every job is completed using high-quality equipment and surface-specific techniques to deliver the highest quality results without damage. Tacoma homeowners and business owners rely on OneGard for three key reasons:

Best Prices Guaranteed — With Membership Savings Built In

We believe professional pressure washing should be affordable and predictable. OneGard offers competitive, transparent pricing backed by our best-price guarantee, along with optional monthly and annual membership plans. These plans allow homeowners to bundle power washing, roof cleaning, and gutter maintenance into one cost-effective program—helping you save money over time while keeping your exterior clean year-round. Free, itemized quotes ensure there are no surprises, pressure, or hidden fees.

Fully Licensed, Bonded & Insured for Total Protection

OneGard is fully licensed, bonded, and insured, carrying comprehensive liability coverage and workers’ compensation to protect your home and our team. Proof of insurance is available on request. Our certified technicians are professionally trained in soft washing, high-pressure cleaning, ladder safety, and site protection. Crews arrive on time, in uniform, respect your property, and follow strict safety and quality standards—so you can feel confident from start to finish.

HOA-Guaranteed, Local Expertise You Can Rely On

Our technicians live and work in the South Sound, giving us firsthand knowledge of Tacoma’s neighborhoods, HOA requirements, and storm-water regulations. We understand where moss builds up fastest, which cleaning methods HOAs approve, and how to protect nearby landscaping and Puget Sound using eco-friendly practices. Our HOA-compliant service packages are designed to keep homes in communities like Fircrest, University Place, and Gig Harbor consistently clean and violation-free—delivering true peace of mind.

Why Tacoma Needs Specialized Power Washing

Tacoma’s wet climate, shaded streets and clay‑rich soils create unique challenges for exterior surfaces. Moss thrives in north‑facing roof valleys, algae streaks form under cedar eaves, and clay residues leave orange stains on patios. Here’s how these issues appear in different neighborhoods and how our team responds:

North End & Proctor District: Older homes with cedar shake roofs and mature fir trees experience heavy moss overgrowth. We apply a gentle soft‑wash treatment that kills moss at the root, followed by installation of zinc strips to slow regrowth.

University Place: A mix of newer vinyl siding and stamped concrete driveways suffers from mildew and clay staining. Our crew uses high‑pressure cleaning on concrete and low‑pressure detergents on vinyl to avoid surface damage while eliminating stains. We finish with a biodegradable protectant that resists future buildup.

Ruston & Point Defiance: Salt spray from the Puget Sound causes grime and oxidation on metal railings, decks and seaside walkways. We combine heated power washing with eco‑friendly, salt‑neutralizing solutions to restore surfaces without harming marine life.

Hilltop & Downtown: Commercial properties deal with graffiti, gum on sidewalks and oil spills in parking lots. Our industrial machines remove gum and oil quickly with hot water and enzyme technology and collect wastewater to comply with city codes.

No matter the neighborhood, we match the pressure, nozzle and detergent to the material. For example, we never use high pressure on asphalt shingles or vinyl siding, and we protect landscaping by pre‑wetting plants and using runoff barriers. For clients in Bremerton, Silverdale and Port Orchard, we schedule maintenance around rainy seasons and provide optional gutter guards to reduce debris.

Local Statistics

Rainy days: ~150 per year in Tacoma.

Average precipitation: ~40 inches annually.

Moss growth season: October through April, when roofs stay damp and receive little sunlight.

Top 7 Reasons Your Lawn Keeps Turning Brown

Pricing & Expectations

Every property is unique, and the cost of power washing depends on several factors:

  • Size of the area: Larger surfaces (driveways, siding, parking lots) require more time and water. We price per square foot for clarity.
  • Material & condition: Soft surfaces like wood and vinyl require gentler techniques and may take longer. Heavy buildup of moss, oil or rust will also increase time and detergent use.
  • Accessibility: Multi‑story homes, steep roofs or obstructed areas may require additional equipment and safety measures.
  • Location: Travel time to outlying areas like Bremerton or Port Orchard may add a small trip fee.

Typical Price Ranges

Our subscription plans start at $55 per month for routine power washing of small patios or driveways. Stand‑alone projects usually range from $0.15–$0.30 per square foot depending on surface and severity. Roof and gutter cleaning packages include moss treatment and start around $300 for a one‑story home. Commercial work (parking lots, storefronts, apartment complexes) is custom‑priced after an on‑site evaluation.

What’s Included

  • Free on‑site estimate and written proposal
  • Full surface evaluation to determine appropriate pressure and solutions
  • Plant and property protection (tarps, runoff barriers, pre‑soaking plants)
  • Complete washing of the agreed‑upon surfaces
  • Post‑service cleanup and debris removal
  • Preventative treatment for moss and mildew when applicable

We believe in transparency: you’ll receive a detailed breakdown of costs and timeline before any work begins. We’ll explain what could raise or lower the price (e.g., combining services reduces per‑item cost) and offer financing or subscription options.

How Our Power Washing Works

Schedule & Plan

Getting started is easy. Call or text (253) 900-2220 or complete our online form. Our office gathers details about your property, the surfaces you want cleaned, and your preferred timing. One of our technicians then performs an on-site assessment—inspecting surfaces, measuring square footage, and identifying problem areas like moss buildup, oil stains, or delicate landscaping. We walk through your goals and answer any questions.

Customized Cleaning & Professional Service

After the assessment, you receive a clear, written proposal outlining recommended services, pricing, estimated duration, and simple prep instructions. On service day, our crew arrives on time, prepares the area, and protects plants, lighting, and surrounding surfaces. We use high-pressure cleaning for concrete and brick, and low-pressure soft washing for siding and roofs. Driveways, patios, walkways, gutters, and downspouts are thoroughly cleaned using plant-safe detergents and surface-appropriate techniques.

Final Walk-Through, Follow-Up & Peace of Mind

Once cleaning is complete, we rinse all surfaces, remove protective coverings, and leave your property clean and tidy. Your technician reviews the results with you, provides maintenance tips, and sends before-and-after photos along with your invoice electronically. Subscription clients receive reminders for future visits, and qualifying roof services include our moss-free warranty, offering long-term protection when paired with preventative maintenance.

FAQs

How often should I pressure wash my home in Tacoma?

Most homes benefit from power washing every 12–18 months. Roofs often require moss treatment every 2–3 years, depending on shade. Gutter cleaning is recommended at least twice a year.

What’s the difference between power washing and soft washing?

Power washing uses high‑pressure water to clean durable surfaces like concrete and brick. Soft washing uses low‑pressure water and specialized detergents to remove mold, mildew and algae from delicate materials like shingles, vinyl siding and painted wood.

Can pressure washing damage my siding or roof?

If done improperly, yes. High pressure on asphalt shingles can strip granules or force water under shingles. That’s why we adjust pressure based on the material and often use soft washing on roofs and vinyl.

Do you use eco‑friendly detergents?

Yes. Our cleaning solutions are biodegradable and safe for plants and pets when used as directed. We also employ water‑recycling equipment to minimize runoff.

Do I need to be home during the service?

No, as long as we have access to the work areas and a water supply. We’ll send before‑and‑after photos and can lock up gates when finished.

Is your work insured?

Absolutely. We carry full liability and workers’ compensation insurance and can provide certificates upon request.

Are there any Tacoma regulations around pressure washing?

Yes. The city prohibits discharging contaminated water into storm drains. We capture and redirect runoff, use approved detergents and comply with municipal codes.

Do you service business districts like Downtown Tacoma or Tacoma Mall?

Yes. We handle commercial properties including storefronts, restaurants, parking lots and multi‑unit buildings throughout Pierce and Kitsap counties.

What does a typical driveway cleaning cost?

The price depends on size and degree of soiling. A 1 000 square‑foot driveway with moderate buildup typically costs between $150 and $250. Combining it with house washing or gutter cleaning reduces the overall cost.

Do you offer discounts for recurring service?

Yes. Monthly or annual plans provide significant savings compared to one‑off bookings. Our packages start at $55 per month.

Do you guarantee your work?

Yes. We offer a satisfaction guarantee—if you’re not happy, we’ll return to fix it at no cost. Our moss treatment includes a two‑year moss‑free warranty when paired with our annual maintenance plan.
