Fence & Deck Cleaning and Sealing in San Mateo County, CA

Fence & Deck Care That Brings the Outdoors Back to Life

Let’s be honest—your fence and deck take a beating. Between the salty air drifting up from the Bay, the fog that rolls in most mornings, and the eucalyptus sap that seems to find every surface, wood and composite materials in San Mateo County age faster than they should. We see it every day.

That’s where Fox Window & Gutter Cleaning comes in. We’ve spent nearly two decades cleaning and restoring fences and decks across Millbrae, Burlingame, Hillsborough, and the rest of San Mateo County. We know exactly what this climate does to wood, and we know how to bring it back. No guesswork, no generic treatments—just real, hands-on care that extends the life of your outdoor investment.

Why Your Fence & Deck Need Professional Attention

If your deck is starting to look gray, chalky, or covered in green patches, you’re not alone. The marine layer keeps things damp well past sunrise, and that moisture sinks into wood fibers. Over time, it breaks down the surface and invites mildew and rot. Your fence takes the brunt of it too, especially on the west-facing sides that get all the wind and weather.

We hear this a lot: “It just looks old.” But the truth is, it’s not old—it’s dirty. And sometimes a deep clean is all it takes to make it look brand new again. Other times, it needs a little more. That’s why we offer both thorough cleaning and protective sealing, depending on what your specific setup needs.

Fence & Deck Cleaning for Homes in San Mateo County

Every neighborhood in San Mateo County has its own quirks when it comes to outdoor surfaces. On the hills near Lomita Park, decks sit at an angle and collect water in spots you can’t easily see. Down closer to the flats, the salty air from SFO and the Bay leaves a fine corrosive film on railings and posts. And in neighborhoods full of mature eucalyptus and pine—like parts of Millbrae and San Bruno—sap and needle buildup can cling to horizontal surfaces and trap moisture against the wood.

We approach each job with that local knowledge in mind. We adjust our pressure, we watch how water flows across your lot, and we make sure we’re not driving runoff onto driveways or patios where older sewer lines are already struggling. It’s the kind of detail that comes from doing this work in this specific area for years. So when we say we’ll treat your fence like it’s our own, we mean it.

What We Can Work On:

  • Wood fences—cedar, redwood, pine—and composite or vinyl fencing
  • Decks, patios, and covered porches of all sizes and elevations
  • Railed walkways and staircases with tight corners or multiple levels
  • Hard-to-reach spaces under overhangs or close to landscaping
  • Surfaces with stubborn mineral stains from Millbrae's hard water supply
  • Post-construction or move-in windows, especially in newer developments around San Bruno or near the bay

Fence & Deck Cleaning in San Mateo County, CA

Let’s be honest—your fence and deck take a beating out here. Between the salty air blowing in from the Bay, the marine layer that rolls in most mornings, and that sticky sap from the eucalyptus trees that line so many Millbrae yards, wood surfaces in San Mateo County get dirty fast. We’re not just talking about a little dust either. We’re talking about that greenish-gray film that makes your deck look old before its time. We strip all of that away so your outdoor space actually looks inviting again.

Our fence and deck power washing services are ideal for:

  • Redwood and cedar decks that have turned gray from sun and moisture exposure
  • Privacy fences along property lines in Lomita Park and Taylor Estates that are covered in green algae
  • Composite decking that needs gentle cleaning without harsh chemical damage
  • Pool decks and patios where slippery surfaces are a genuine safety hazard
  • Stained or painted fences that need a good scrub before their next coat

How We Tackle Fence and Deck Cleaning

We don't just blast water at things and hope for the best. Our process is methodical, and it's built specifically for the conditions here in San Mateo County:

1. Surface Assessment

First, we walk the whole area. We check for loose boards, raised nails, or rotten spots on your deck. We also look at what kind of wood you have—redwood, cedar, pressure-treated pine—because each one needs a different approach. And we check the slope of your yard, especially on those hilly lots in the Green Hills area, so we can manage water runoff properly and avoid flooding your neighbor's driveway.

2. Choosing the Right Pressure Level

Here's the thing about power washing: too much pressure and you'll gouge the wood. Too little and you're just moving dirt around. We adjust our equipment based on what we find. A soft wash works better on older, weathered wood, while a stronger stream handles that caked-on grime near the ground. We also keep in mind that our older sewer mains in the Green Hills area struggle with heavy water flow, so we're mindful about where wastewater goes and how much we use.

3. Cleaning Solutions & Treatment

We use eco-friendly, biodegradable cleaners that break down mildew, algae, and sap without harming your plants or your pets. For those stubborn hard water stains around sprinkler heads or the mineral deposits left by our local tap water, we've got targeted treatments that handle it. We let the solution sit for a few minutes to do its work before rinsing—this is where the magic actually happens.

4. Rinsing and Detail Work

We rinse thoroughly, making sure no cleaner residue is left behind. Then we go over the details: the corners, the gaps between boards, the areas under railings. We clear out the debris that accumulates where your fence meets your house. And we pay extra attention to the side of your fence that faces the wind—if you're west of El Camino Real, that side takes the brunt of the salty air and needs a more thorough rinse.

5. Final Inspection

Before we wrap up, we'll walk the property with you and inspect the fence and deck work together. We want you to see the difference up close—and if anything isn't perfect, we'll make it right on the spot.
