Let’s be honest—your exterior windows take a beating out here. Between the marine layer rolling in from the Pacific, the mineral-heavy tap water, and the salty air drifting up from the Bay near SFO, it doesn’t take long for that chalky film and stubborn grime to settle in. You look through them and everything’s just… hazy.
That’s where we come in. Fox Window & Gutter Cleaning has spent nearly two decades tackling exterior window cleaning across San Mateo County. We know exactly what it takes to cut through the hard water spots on a mid-century ranch in Lomita Park or get the soot off a double-hung window on Broadway. We’ll leave your glass spotless, streak-free, and clear enough that you’ll forget the fog even exists.
Here’s the thing about exterior windows: they’re the first thing people see, and they’re also the most neglected. Rain and fog might rinse away loose dust, but they actually make hard water staining worse. And when the summer wildfires kick up ash and soot from the North Bay or Santa Cruz Mountains, that fine layer of debris bakes onto the glass. We see it every late summer.
Professional exterior window cleaning doesn’t just make your view better. It protects the glass and frames from corrosion—especially those older aluminum frames on the 1950s and 60s homes in Taylor Estates. It cuts down on allergens that collect on the sills. And honestly, when you’re in a neighborhood like Hillsborough or Burlingame, curb appeal matters.
We handle exterior windows on every type of home in San Mateo County. From the classic split-levels scattered around Green Hills to the larger estates in Hillsborough, we’ve got the right approach for your specific setup. Sloped lot? No problem. We use proper ladder stabilization techniques that keep us safe on the hillside neighborhoods near Lomita Park.
The truth is, exterior work requires different products than interior glass. We use specialized, eco-conscious solutions—including the right acid-based cleaners for Millbrae’s hard water residue—that won’t harm your landscaping or leave runoff behind. And because some of the older sewer mains in the Green Hills area can’t handle heavy water, we’re careful about how we rinse and where the wastewater goes. That’s the level of local know-how you’re getting.
We’ll also clear sticky pine sap from the trees that crowd many of these older properties, and we’ll handle the fine ash that the wildfire season tends to deposit on glass. Your windows won’t just be washed; they’ll be handled by people who understand San Mateo County conditions.
A clean storefront, office, or building exterior reflects the professionalism of your business. Clients notice when glass is sparkling clean—and they notice when it’s not. We work around your business hours to minimize disruption, and we’re fully insured for your peace of mind.
Whether you’ve got a handful of windows in a Burlingame bungalow or a sprawling Hillsborough estate with 100 panes, we’ve got you covered. Our team has cleaned just about every style you’ll find in San Mateo County—and we handle each one with the right technique and care. Here’s what we regularly work on:
We don’t just spray and wipe. When you book exterior window cleaning with us in San Mateo County, we follow a process that’s been refined through years of dealing with coastal fog, hard water, and that salty air drifting in from the Bay. Every appointment includes:
Honestly, figuring out how often to schedule exterior window cleaning in San Mateo County isn’t a one-size-fits-all answer. It depends on where you live, what’s growing around your property, and how much you actually notice the buildup. If you’re in Millbrae’s Taylor Estates, those eucalyptus trees dropping sap and needles mean your windows are working overtime compared to a home near downtown. That’s why we offer recurring service plans — we set a schedule that makes sense for your specific spot, knock the work out, and send you a friendly reminder when it’s time to book again. No stress, no remembering, just clear glass all year. Here’s what we generally recommend:
