About this service
Skylight Cleaning Pasadena CA: What the Work Actually Involves
Skylight Cleaning Pasadena CA is the roof-access glass service that removes hard water stains, dust, mold, and debris from skylights and reseals the frame so water stays outside. We climb the roof, hand-scrub the glass with purified water and a squeegee, clear the surrounding gutter line, and check the flashing and sealant while we are up there. Most homes take 45 to 90 minutes per skylight, and we never walk a tile or slate roof without fall protection.
Pasadena sits under a dry, sunny climate that bakes mineral deposits onto skylight glass, and the winter rains then find every failed seal. That combination is why so many homeowners search for skylight cleaning in Pasadena CA near me after the first storm of the season. If you live near Linda Vista or Bungalow Heaven, tree sap and dust add a second layer that blocks daylight and traps heat. We remove both, then re-seal the frame so the glass stays clear through the next wet season.

What's included
What Our Skylight Cleaning Service Includes
Every skylight visit covers roof-safe access, glass cleaning, stain removal, and a seal check. We tell you upfront what is included and what is a separate add-on, so there are no surprises on the invoice.
Glass and Frame Cleaning
We clean the skylight glass inside and out, plus the frame and curb. Purified water and a squeegee leave a streak-free finish. Dust, pollen, and cobwebs come off in the same pass.
Hard Water Stain Removal
Mineral spots get treated with a hard water remover and glass scraper. We lift the calcium and silica film without scratching the pane. Heavy etching may need a second visit, which we quote upfront.
Seal and Flashing Inspection
We check the sealant, flashing, and fasteners while we are on the roof. Failed sealant gets reapplied with roof-grade material rated for Pasadena heat. We photograph anything that needs a follow-up.
Gutter and Debris Cleanup
Debris we knock loose gets bagged and removed, and we clear the gutter line near the skylight. Your roof drains properly when we leave. We haul everything away with us.
How it works
Our Skylight Cleaning Process, Step by Step
We start with an extension ladder and OSHA-compliant fall protection, then lay down drop cloths to protect your roof and landscaping. You get a quick walkthrough of what we found up top, including any cracked glass or loose flashing. Setup takes 10 to 15 minutes.
Leaves, twigs, and dust come off first with a soft brush and gutter scoop. We bag the debris rather than washing it into your gutters or flower beds. On Pasadena homes with mature oaks, this step alone can fill half a bucket.
We scrub the skylight with purified water, a soft wash solution, and a microfiber cloth, then use a glass scraper and hard water remover on mineral spots. A squeegee finish leaves the glass streak-free. Expect 20 to 40 minutes per skylight depending on buildup.
While we are on the roof, we inspect the frame, curb, and flashing for gaps, cracked sealant, or rusted fasteners. We reapply roof-grade sealant where it has failed. If we find a problem we cannot fix that day, we tell you before we leave.
You get a look at the finished skylight from inside and out, plus photos of the roof work. We clear the gutters we disturbed and haul away all debris. The whole visit usually runs 60 to 120 minutes for a typical Pasadena home.

Tools & methods
Tools and Methods We Use on Pasadena Skylights
Ettore and Unger squeegees
Professional-grade squeegees with fresh rubber leave skylight glass streak-free. We swap blades between jobs so you never get a smeared finish.
Water-fed pole
Reaches high or steep skylights with purified water, cutting the time we spend on a ladder. It is ideal for tall atrium glass and second-story skylights.
Glass scraper and hard water remover
Lifts baked-on calcium and silica without scratching the pane. Essential on Pasadena skylights that face the sun all summer.
Microfiber cloth and towels
Wipe frames, sills, and screens without leaving lint or streaks. We color-code cloths so glass and frame rags never mix.
Extension ladder and OSHA safety gear
Gets us safely onto every roof pitch, with harnesses and stabilizers. Required on every skylight job, no exceptions.
Gutter scoop and screen repair tool
Clears the gutter line above the skylight and replaces torn vent mesh in the same visit. Small tools that prevent big water problems.
Real results
Before and after.
Skylight Cleaning
Cloudy Bungalow Skylight Restored
A 1924 Bungalow Heaven home had two skylights with 15 years of hard water stains. The glass looked frosted from inside, and the hallway felt like a cave. A previous cleaner had quoted a full replacement at $1,800.
After: We scraped the mineral layer, polished with purified water, and resealed both frames. Light transmission improved noticeably, and the homeowner measured the hallway as visibly brighter. Total cost was $340, a fraction of the replacement quote.

Skylight Cleaning
Leaking Kitchen Skylight Sealed
A Linda Vista home had a skylight dripping onto the kitchen counter after every storm. The ceiling showed a spreading brown stain, and the homeowner was worried about mold. The glass itself was intact.
After: We cleaned the glass, cleared the clogged weep channel, and reapplyed roof-grade sealant around the flashing. The drip stopped through the rest of the rainy season, and the ceiling stain dried out. The repair cost $260 versus a $1,200 ceiling repair.

Skylight Cleaning
Office Atrium Glass Cleared
A South Lake Avenue District office had six atrium skylights with dust, water spots, and one torn vent screen. Tenants complained the lobby felt dim, and a small drip was forming near a light fixture.
After: We cleaned all six skylights, replaced the torn screen mesh, and resealed two frames. The lobby brightened, the drip stopped, and the property manager scheduled us for an annual visit. The job took one early-morning shift.

Skylight Problems We Fix for Pasadena Homes
Pasadena skylights fail in predictable ways: mineral stains, dried seals, torn screens, and clogged gutters. Here are the problems we solve most often, and what happens if you leave them alone.
Ask a pro →Cloudy, etched skylight glass
We strip the mineral layer with a glass scraper and hard water remover, then polish with purified water and a squeegee. Most panes come back clear in one visit. If the glass is too far gone, we tell you before you spend money on a cleaning.
Leaking skylight after rain
We clean the glass, clear the weep channel, and reapply roof-grade sealant around the frame and flashing. Skylight cleaning for leaking skylights Pasadena CA customers call about is one of our most common jobs. Most drips stop after one visit.
Torn vent screens and clogged gutters
We replace torn screen mesh with new material and clear the gutter line with a scoop. It is a small fix that prevents bigger water problems. We handle both in the same roof visit.
Mold and algae on the frame
We treat the frame with a soft wash solution that kills mold without damaging roofing material. Then we clean and reseal the area. It keeps the skylight looking new and stops the spread.

What Skylight Cleaning Costs in Pasadena
$150 - $450 per skylight, with resealing adding $60 - $150
Typical 2026 pricing for skylight cleaning in Pasadena runs $150 to $450 per skylight, with most single-skylight homes landing near $200. Roof pitch, height, stain severity, and skylight count drive the number. Resealing adds $60 to $150 when the flashing needs work. We quote a flat price before we climb, so you know the total before any work starts. No hourly meter, no surprise add-ons at the door.
A $200 cleaning that prevents a $1,200 ceiling repair pays for itself the first rainy season. Add the daylight and lower cooling load, and the math gets even better.
•affects cost
A steep second-story roof takes longer and more safety gear than a flat single-story roof. That labor shows up in the price. Homes in the hills above Linda Vista often sit at the higher end.

Light dust wipes off in minutes; years of baked-on hard water takes scraping and repeated passes. Heavy etching may need a second visit, which we quote upfront rather than surprising you later.

The first skylight carries most of the setup cost. Each additional skylight on the same roof is cheaper because we are already up there with gear in place. Bundle them in one visit to save.

If the sealant has failed, resealing adds $60 to $150 depending on the size and access. We photograph the problem and quote it before touching anything. Skipping the reseal usually means a leak later.

Customer reviews
What Pasadena Customers Say About Our Skylight Work
★★★★★
“Our 1920s bungalow has two original skylights that had gone cloudy and started dripping last winter. The crew cleaned both, scraped off years of hard water stains, and resealed the flashing. No leaks through the whole rainy season, and the hallway is noticeably brighter. They even cleared the gutters while they were up there.”

“I called after a skylight leaked onto our kitchen ceiling. They found a failed seal, not a broken pane, and fixed it the same visit. The glass came out streak-free and they showed me photos of the resealed frame. Fair price, no upsell, and they were careful on the tile roof.”

✓ Verified★★★★★
“We manage a small office building with atrium skylights that were blocking light and showing water spots. Rose City cleaned all six, replaced a torn vent screen, and resealed two frames. Clear glass, no more drips in the lobby, and they worked around our tenants without a complaint.”

Priya S.Property Manager, South Lake Avenue District
✓ VerifiedMost Pasadena skylight cleanings run $150 to $450 per skylight in 2026, depending on roof pitch, height, and stain severity. A single easy-access dome skylight sits at the low end; a steep tile roof with heavy hard water stains sits at the high end. Resealing adds $60 to $150 if the flashing needs work.
Clean skylights once a year in Pasadena, ideally in early fall before the rainy season. Homes under oak or sycamore trees should book twice a year because sap and dust build faster. If you can see a cloudy film or mineral spots from inside, that is your cue to call.
No, skylights require roof access, and we always use an extension ladder with OSHA-compliant fall protection. We never clean skylights from the ground with a long pole alone because you cannot inspect the flashing or seal that way. Roof access is what lets us catch leaks before they stain your ceiling.
A skylight that leaks after rain almost always has a failed seal or clogged weep channel, not cracked glass. Pasadena's summer heat dries out roof sealant, and the first storm finds the gap. We clean the glass, clear the channel, and reapply roof-grade sealant, which stops most drips in one visit.
