Commercial and Residential Window Cleaning in San Mateo County, CA

Brighten Your View. Boost Your Curb Appeal. Protect Your Investment.

Windows are more than just glass—they’re your connection to the outdoors. They pull in that soft California light, frame the hills of Millbrae, and give your property a whole different feel. But let’s be honest: between the coastal fog, the mineral-heavy tap water, and the occasional wildfire smoke drifting down from the North Bay, windows around here take a beating. That chalky residue, those stubborn spots—it’s not just dirt. It’s a buildup of everything San Mateo County throws at your glass.

That’s where Fox Window & Gutter Cleaning comes in. With nearly two decades of experience serving San Mateo County, we handle both commercial and residential window cleaning with the same level of care. We’ve cleaned everything from mid-century ranches in Lomita Park to second-story commercial units above Broadway. The result? Streak-free, spotless glass—inside and out—that actually looks clear.

Why Clean Windows Matter

Most folks don’t realize how bad their windows have gotten—until they see them clean again. Then it hits you. That view you thought was permanently foggy? It was just buildup. Clean windows don’t just look better; they make your whole space feel brighter, healthier, and more efficient. Whether you’re dealing with salt air corrosion from being west of El Camino Real, sticky eucalyptus sap from those big trees near your roofline, or just the regular dust that settles on everything, professional window cleaning helps.

Residential Window Cleaning

Your home is your most important space, and clean windows help it look and feel its best. Our residential window cleaning is designed to be efficient, thorough, and safe for all home types—from single-story ranches to multi-level estates. We get it: homes in San Mateo County aren’t all the same. Those split-levels from the ’60s and ’70s? They’ve got aluminum frames that need a gentle touch. The older double-hungs downtown? We’ve handled sash cords that needed replacing mid-clean. So we adapt. We treat your home like it’s our own—removing shoes or wearing covers indoors, protecting floors and furniture, and using safe, eco-conscious products that won’t harm your landscaping or your family.

We Clean:

  • Interior and exterior window glass
  • Skylights and solar tubes
  • Sliding glass doors and French panes
  • Screens, sills, and tracks
  • Hard-to-reach or second-story windows
  • Post-construction or move-in window cleaning in San Mateo County

Our Window Cleaning Process

We don't just spray and wipe. Here's our step-by-step approach that gets windows spotless and keeps them that way:

1. Assessment

First, we walk the property. With homes in Taylor Estates or commercial spots near SFO, we check window size, how they open, and any tricky spots. We look for hard water stains—common with Millbrae's mineral-heavy tap water—or oxidation on older aluminum frames. This helps us plan the right approach for your specific situation.

2. Prep & Protection

We lay down drop cloths on your floors, cover furniture, and protect landscaping outside. Because we know many homes here sit on sloped lots with mature eucalyptus trees, we're careful about where we step and what we set our equipment on. We don't leave a mess, period.

3. Screen & Track Cleaning

We pull out each screen, give it a gentle scrub with a soft brush and solution, then rinse it clean. The tracks? We vacuum out the dirt and wipe down sills—something a lot of companies skip. It's the details that make your windows look brand new.

4. Glass Cleaning (Interior & Exterior)

We use eco-friendly, ammonia-free cleaners that cut through the grime without harsh fumes. For stubborn hard water spots—those chalky white deposits from our local groundwater—we apply a safe, acid-based solution that breaks them down. Then we hit the glass with professional-grade squeegees for a streak-free shine, even on those fog-affected panes that seem to attract every mineral in the air.

5. Final Inspection

Before we wrap up, we walk the property with you, checking every pane and frame. The truth is, we want you to see the difference yourself—if something's not right, we'll make it right, right then and there. That's our promise for every commercial and residential window cleaning job in San Mateo County, CA.

  • Full inspection of windows and screens — we'll point out any cracked seals or worn sash cords before they become a problem
  • Interior and exterior cleaning — we use acid-based solutions for that hard water residue from the Santa Clara Valley Basin, not just soap

How Often Should You Clean Your Windows in San Mateo County?

Honestly, there’s no one-size-fits-all answer. It depends on your home’s exposure, how much time you spend looking out those panes, and what your schedule allows. But here’s a rule of thumb we give folks in San Mateo County: when you start noticing that hazy film or those stubborn spots, it’s time to call. For most of our clients in Millbrae and the surrounding neighborhoods, that shakes out to a few times a year. We make it easy to stay on top of it with recurring service plans — you get a discount, and we send you a friendly reminder when you’re due. No need to keep track yourself. Here’s what we typically suggest:

  • Every 3–6 months for homes in coastal areas like Millbrae or near the Bay — the marine layer and salt air do a number on glass.
  • Quarterly for commercial storefronts, especially along Broadway in downtown Millbrae or in downtown San Mateo, where first impressions matter.
  • Twice a year for standard home maintenance — once after the rainy season ends (think May) and once before the holidays.
  • Before open houses, listing photos, or big events — if you're selling or hosting, sparkling windows can make all the difference.
