Fairfax VA Patio and Deck Washing Services.

Decks and patios take a beating in Northern Virginia. Between spring pollen, summer humidity, fall leaves, and year-round foot traffic, that outdoor space you use for grilling and entertaining starts looking pretty rough. Algae grows in the cracks. Wood turns gray. Composite materials get streaked with mildew. And before you know it, you're avoiding your own backyard.

Here's the thing about cleaning decks and patios: the wrong approach causes real damage. Too much pressure splinters wood, etches composite boards, and can even strip sealant you paid good money to apply. The wrong cleaner? That can discolor surfaces or kill the plants around your patio.

We know what we're doing.

Our team has cleaned hundreds of decks and patios across Fairfax, Woodbridge, Manassas, Bristow, and Gainesville. We've worked with pressure-treated lumber, cedar, composite decking, stamped concrete, pavers, and natural stone. Each material needs a different approach—different pressure, different cleaning solution, different technique.

What to expect:

  • We inspect first to spot loose boards, damaged areas, or problem spots
  • We pre-treat stains with the right cleaner for your surface
  • We use low-pressure soft washing on wood and composite (no splintering, no gouging)
  • We use surface cleaners on concrete and pavers for even results
  • We post-treat to prevent algae and mildew from coming back too quickly

If you've been putting off cleaning your deck or patio because you're worried about damage—or because you tried it yourself once and hated the results—give us a call at 703-853-4738. We'll walk you through what we'd do, answer your questions, and give you a free quote.

Let's get that outdoor space looking good again.

Driveway Pressure Cleaning in Fairfax VA.

Your Driveway is the first thing that friends and neighbors see. Concrete driveways are perfect for pressure washing to keep them looking great for years. Curb appeal is important in Fairfax, VA and one of the easiest ways to maintain curb appeal is keeping the exterior of your home and surrounding property as clean as possible.

Driveways get dirty quickly and are a pain to clean. At Diamond Power Washers, we use a unique mix of cleaning solutions along with the latest power washing equipment to restore your driveway to its original condition. Our power washer Technicians are trained in cleaning all types of concrete and walkways. Let us show you just how great they look under that dirt and grime.

Commercial Power Washing in Fairfax VA

Your storefront, parking lot, and sidewalks say a lot about your business before customers ever walk through the door.

If the entrance is covered in gum stains, the windows are streaked, or your parking lot has oil spots and tire marks everywhere—people notice. And in Fairfax, where you're competing with every other business on Route 50 or Fairfax Boulevard, first impressions matter.

Here's what most business owners don't realize: that buildup isn't just ugly. Algae on sidewalks becomes a slip hazard (and a liability). Grease on loading docks violates health codes. Mold and mildew on exterior walls can work their way inside. And the longer you wait, the harder everything is to clean.

We handle commercial properties differently than residential.

We schedule around your business hours so we're not blocking your entrance during the lunch rush or scaring off customers. We know which cleaning solutions are safe for different surfaces—brick, concrete, metal siding, glass, awnings. And we manage water runoff properly because Fairfax County has regulations about what goes into storm drains.

What we clean:

  • Storefronts and entryways
  • Parking lots and garages (oil, grease, tire marks)
  • Sidewalks and walkways (algae, gum, stains)
  • Building exteriors (brick, siding, stucco)
  • Dumpster pads and grease traps
  • Graffiti removal

If you manage a retail center, restaurant, office building, or any commercial property in Fairfax, we've probably worked on something similar. Call us at 703-853-4738 for a free quote. We'll come look at your property, tell you what we'd do, and schedule it at a time that works for your business.

Fairfax Power Washing Frequently Asked Questions

It depends on the size of your property and what you need cleaned. House washing for a typical Fairfax home runs $300-$600. Driveway cleaning is usually $150-$300. Roof cleaning starts around $400-$700. The biggest factors are square footage, how dirty the surface is, and what material we’re cleaning.  Call us at 703-853-4738 or get an instant quote here.

Late April or early May, right after pollen season ends but before summer humidity kicks in. That yellow pollen coating stains everything, and our humid summers accelerate algae growth. A fall cleaning (September or October) is also smart—it removes leaf debris and prepares your exterior for winter. If you can only clean once a year, do it in spring. Twice a year is better for Fairfax’s climate.

Soft washing uses low pressure (like a garden hose) plus specialized cleaning solutions to kill algae, mold, and mildew at the root. Pressure washing uses high pressure to blast away dirt and stains. We use soft washing on delicate surfaces like vinyl siding, roofs, and painted wood. We use pressure washing on tough surfaces like concrete driveways, sidewalks, and parking lots. Using the wrong method damages your property—we’ve seen plenty of DIY disasters from people who didn’t know the difference.

Not if it’s done right. High pressure will absolutely crack vinyl siding, force water behind panels, or strip paint. That’s why we use soft washing on all siding—it’s gentle enough to protect the material but strong enough to remove years of buildup. We’ve cleaned thousands of Fairfax homes without damaging a single panel. If someone shows up with a pressure washer set to maximum and starts blasting your house, stop them.

Once or twice a year for most homes. If your house is in a shaded area or near lots of trees, you might need it more often—shade and moisture create perfect conditions for algae and mildew. Properties along busy roads like Route 50 or Fairfax Boulevard accumulate more dirt and exhaust grime. HOA communities often require annual cleaning to meet community standards. Bottom line: if you see black streaks, green algae, or heavy pollen stains, it’s time.

You can, but it’s risky. We see DIY damage almost every week—cracked siding, stripped paint, water forced behind exterior walls, splintered decks, broken windows. Consumer-grade pressure washers from Home Depot don’t have adjustable pressure or the right nozzles for different surfaces. If you use too much pressure, you’ll cause permanent damage. If you use too little, you won’t actually clean anything. And if you don’t kill the algae and mildew properly, it comes right back. Most people try it once, hate the results, and call us to fix it.

Yes, if we use hot water and the right cleaning solution. Oil soaks into concrete, so cold water pressure washing alone won’t cut it. We pre-treat oil stains, use hot water power washing, and then post-treat to prevent staining. Old, set-in stains (especially on unsealed concrete) might not come out 100%, but we’ll get them significantly lighter. Sealing your driveway after cleaning helps prevent future stains.

Yes. We’re fully licensed and insured in Virginia. We’re also veteran-owned, which means we bring military discipline and attention to detail to every job. You can check our reviews and credentials before hiring us.
