Skylight Cleaning

Brighten Your Skylight. Let the Light In. See the Bay Area Clearly.

Skylights are one of those things you don’t think about until they’re dirty. Then one day you look up and notice that hazy film, those water spots, maybe a few dead bugs trapped in the corners. It’s not just about looks—a grimy skylight blocks the natural light that makes your home feel open and airy. And here in San Mateo County, where the sun is a big part of why we live here, a cloudy skylight is a real disappointment.

That’s where Fox Window & Gutter Cleaning comes in. With nearly two decades of experience serving San Mateo County, we provide detailed, professional skylight cleaning that gets your glass crystal clear—inside and out. We handle the tricky angles, the steep roofs, and the stubborn hard water spots so you don’t have to.

Why Clean Skylights Matter (Especially Here)

Let’s be honest—skylights are a magnet for grime. Between the coastal fog that rolls in from the Pacific and the mineral-rich tap water we’ve got in Millbrae and the rest of San Mateo County, that glass takes a beating. The fog leaves a fine mist that dries into a chalky residue. The hard water leaves those stubborn white spots that just don’t wipe off with a cloth. And if you’ve got eucalyptus or pine trees near your roof, you’re also dealing with sap and needles that cling to the glass.

We’ve cleaned skylights in just about every neighborhood in this county—from the sloped lots in Taylor Estates to the older ranch homes in Lomita Park. And we’ve seen it all. That’s why we don’t use a one-size-fits-all method. We assess what kind of buildup you’ve got, whether it’s hard water, soot from wildfire smoke, or just plain dust, and we pick the right cleaning solution for the job.

Residential Skylight Cleaning

Your home is your sanctuary, and a clean skylight makes a huge difference in how that space feels. We get it—not everyone is comfortable getting on a ladder and scrubbing a sloped glass panel on their roof. But that’s exactly what we do, and we’re good at it.

Whether you’ve got a fixed skylight in the living room, a vented one in the kitchen, or a solar tube in the hallway, we clean it safely and thoroughly. We use eco-friendly cleaning solutions that won’t harm your landscaping or your family, and we’re careful not to leave any mess behind. We respect your home—we’ll take our shoes off or wear shoe covers, protect your floors, and make sure everything looks better than we found it.

And for those of you in San Mateo County with older aluminum-frame skylights, we know how to handle them. The salt air from the Bay and SFO can cause corrosion, so we treat those frames gently and make sure they’re not damaged during cleaning.

We Clean:

  • Interior and exterior skylight glass
  • Solar tubes and tubular skylights
  • Skylight frames and seals, checking for wear
  • Hard-to-reach or second-story skylights
  • Windows and doors that might also need a little TLC while we're up there
  • Post-construction or move-in windows

We’ll get them so clean, you’ll feel like you’ve added a new window to your home.

How We Clean Your Skylights

Here's what you can expect when you book us for skylight cleaning in San Mateo County:

1. Inspection

We start by checking your skylight for any cracks, leaks, or loose seals. Given the salty air near SFO, we're also on the lookout for corrosion on the frame. We'll point out any issues before we start scrubbing.

2. Prep & Safety

Skylights are tricky—they're up high and often on a slope. Our team sets up ladders with stabilizers, especially for those sloped roofs in Lomita Park or Taylor Estates. We also protect your landscaping below; we don't want to drip soapy water all over your prized hydrangeas.

3. Gentle Cleaning

We use a soft brush and an eco-friendly, ammonia-free solution to lift off the grime, pollen, and that sticky sap from the eucalyptus trees that are everywhere in Millbrae. Then we rinse and squeegee to a streak-free shine. No harsh acids unless you've got serious hard water spots—and if we do use something stronger, we'll tell you and make sure it's safe for your roof.

4. Detail Work

We wipe down the edges, clean the surrounding roof area if needed, and make sure no debris is left behind. If you've got multiple skylights, we'll do them all so they match in brightness.

5. Final Walkthrough

Before we wrap up, we walk around with you and check the skylight together. Because the truth is, we want you to see the difference — especially with all that ash and sap from the eucalyptus trees in Millbrae. If it's not streak-free and spotless, we'll make it right. Choosing the best window cleaning service in Millbrae means finding a team that pays attention to these details.

Skylights We Clean

Skylights aren’t just another window. They’re overhead, angled, and catch every bit of dust, pollen, and that fine Bay Area grime. Whether you’ve got one above the stairs or five in a great room, we’ll get them clean—safely and without you worrying about a ladder on a sloped roof. We handle all styles and setups, including:

We Clean:

  • Fixed skylights on flat or pitched roofs
  • Vented and solar-powered skylights
  • Tubular skylight shafts
  • Skylights with hard-to-reach angles
  • Old skylights with fragile seals and frames
  • Skylights on vaulted ceilings in Taylor Estates
  • Custom architectural skylights near downtown Broadway

What's Included in Every Skylight Cleaning Appointment?

We know what happens to skylights in Millbrae. The marine layer rolls in, leaves a fine mist, and suddenly that clear glass above your kitchen looks foggy and dull. Plus, if you’re anywhere near the Lomita Park neighborhood, the pines are dropping needles and sap that just bake onto the glass in the summer. When you book with Fox Window & Gutter Cleaning for skylight cleaning, we handle all of that. Every appointment includes:

  • Full inspection of the skylight, frame, and flashing
  • Interior and exterior glass cleaning
  • Gentle removal of hard water spots and mineral residue
  • Clearing debris from the surrounding roof area
  • Streak-free finishing, even on those sloped angles
  • Detail check for any seal cracks or potential leaks

How Often Should You Get Your Skylights Cleaned?

Honestly, keeping skylights clean around here isn’t just about looks—it’s about letting that Bay Area light in. But if you’re like most folks in San Mateo County, you probably don’t think about your skylights until they’re streaky or fogged over. That’s where we come in. We offer recurring skylight cleaning plans with discounts and easy reminders, so you never have to remember. How often should you schedule? It depends on your home, your trees, and how much coastal fog you deal with. Here’s what we usually suggest:

  • Every 3–6 months for homes in coastal or high-traffic areas—think Millbrae hills or anywhere west of El Camino Real where salty air and fog leave a film
  • Quarterly for businesses or storefronts with skylights that need to look sharp for customers
  • Twice per year for standard home maintenance—perfect for many split-levels in Lomita Park or Taylor Estates
  • Before special events, home listings, or seasonal transitions—especially after wildfire season when ash settles on everything
