Yes, the same two people clean your gutters and the outside of your windows in one visit. We do the gutters first and the glass last, so the runoff never lands on clean panes. We price by the number of stories and the approximate window count, and booking both jobs together costs less than two separate trips. Most of our Foster City customers book this in the spring and fall, when leaves and grime build up fastest.
Priced by stories, not by a visit. The bundle costs less than two trips, and the number on the phone is the number on the invoice.
We price by the number of stories and the approximate number of windows, and the bundle, done in one visit, costs less than booking the two jobs separately. The two people who work your house are our window cleaners and our gutter crew, so one quote covers both. The number we give you on the phone is the number we charge, so tell us your stories and window count and we will give you the figure from our professional window cleaning rate before anyone is scheduled. Downspout flushing, screen rinsing and sill wiping are part of the window washing and gutter job, not billed as extras. Clean gutters and glass also help curb appeal, which is why many owners book both.
What moves the quote on the day is usually what the crew sees when it gets up the ladder. A third story or a steep roof takes longer to work safely, and multi-story buildings with several roof lines take the longest. Oversized picture windows and a high count of small panes add time at the glass. The windows inside stay out of the quote because we clean the exterior only. Gutters that have not been cleaned in years, or that are packed with needles and leaves, need more passes. Gutter guards have to be lifted and reseated before the run can be cleared, and hard-water spotting from sprinklers is a stain that no cleaning removes, so we flag it rather than promise it away. If clogged gutters have already let water run down the fascia, we photograph the damage and tell you what we saw, because water damage is not something a cleaning fixes.
On a recent Foster City job we took one look at a two-story house with a sprinkler line hitting the front glass and the gutters full at the corners, and that combination moved the quote on the stories and the spotting, not on the window count. We now ask every customer for the number of stories and a text photo of the front of the house, because that gets us to an exact figure faster than any estimate from memory. Send the photo and we will tell you what we are looking at.

For context, nationally. Angi puts the average US gutter cleaning at $168, most homeowners paying $119 to $234 (Angi, 2026). Exterior-only window cleaning runs roughly $4 to $10 per window, or $100 to $250 for a typical home, with $3 to $5 per window more on upper stories (Angi, HomeGuide, via Google AI Overview, Oct 2026). Priced by stories, the most common model, a two-story gutter cleaning sits around $150 to $300 nationally. If a quote you are holding sits far outside these, ask what is driving it.
On every house we work, the first scoop out of a gutter ends up on the wall below it. We put the glass last so it ends up there once.
Gutters first, glass last. That is the order on every job our crew does, and it is the reason we book both with one crew instead of sending two.
What we see from the ladder. When we clear a run, the leaves, the grit and the black water that sits under them come down the wall and across any window below it. Flushing a downspout throws more of it, in a stream, onto the panes beside the outlet. If the glass was washed first, someone has to wash them again before we are off the ladder. So we do the roof blow-off, clear the gutters, flush every downspout, give the wall a few minutes to stop dripping, and only then start on the glass. The panes under the downspout outlets are the last ones we touch on the house.
Two things we do differently from a window-only crew. We rinse the siding under each run before we move to the glass, so nothing left on the wall washes down onto it in the first rain. And we do the top-floor glass from the same ladder position as the gutter run, one setup per side of the house, which is where the bundle saving comes from: no second trip, no second setup.
Downspouts flushed, screens rinsed, sills wiped, bags hauled. None of it shows up as a line item.
Gutters. Roof blow-off where debris sits above the gutter line. Every run hand-cleared, not just the visible stretch from the ground. Every downspout flushed with water until it runs clear, and a blocked one cleared on the spot where it can be reached from above. A downspout that feeds a buried drain line is checked at the outlet; clearing the buried line is a separate job, quoted before anyone touches it. Debris bagged and taken away. Before-and-after photos of each run, sent to you before the crew leaves.
Windows, exterior only. Every reachable pane on the outside of the house, cleaned with a water-fed pole and purified water so the glass dries without streaks or towel lint. Frames wiped. Screens taken down, hand-rinsed and put back on request. Sills wiped. Upper-story windows done from the pole, not from a ladder leaned on the siding.
Not included, and we say so up front. Interior glass. Hard-water or sprinkler staining etched into the glass, which needs a separate mineral treatment and is quoted after the crew sees it. Post-construction paint, stickers or stucco. Skylights and solar panels. Pressure washing of siding, decks or driveways. Gutter guards: if a run is covered, lifting and reseating the guard adds time and is quoted by the foot before the visit, never on the day.
Twice a year for both, and the same two months, which is why one visit covers it.
Most of our Foster City customers book both twice a year, in the spring and in the fall, and that is why one crew in one visit makes sense for this city. Cleaning services scheduled at the same two points in the year keep the calendar simple, and a schedule service visit each season catches the build-up before it gets bad.
In the spring we find a pollen film on the south-facing glass and a sticky paste of blossom packed into the downspout elbows. By fall the leaf load is what we are clearing, and the wet mat sits in the gutters through the rainy months. Storm and wind seasons can move the dates by a few weeks in either direction, so we set the visit off what the roof looks like rather than the calendar alone. The clean windows you get in the spring are the ones that stay clear through the summer haze, and every window on the south side picks up the dust first. A sill that has collected grit in the winter is easier to wipe the day it is cleaned than after a season of rain.
Some houses need a third visit. Heavy tree cover over the roof is the most common reason, since needles and grit pack the downspouts between cleanings. A sprinkler line that hits the glass is the other, because those spots come back a day after a cleaning, and a residential window in that spot is the first to show it. Residential properties on a busy road or next to construction collect dust faster than the rest. On the windows, the sign you need a visit is a haze you only notice when the sun is low. On the gutters, it is water sheeting over the edge in a rain.
Most two-story homes are done in a morning. You do not need to be there, and you get the photos either way.
The crew calls the day before with a two-hour arrival window, and again when they are on the way.
How long. This Old House puts a professional gutter cleaning at 30 minutes to an hour on a typical house. Exterior windows on the same house run about the same again or a little more, so plan on a morning for a two-story home and most of a day for three stories or a house with a lot of glass. Gutters that have not been touched in years, steep roofs and wraparound porches run longer.
Before the crew arrives. Turn the sprinklers off the night before, so the glass is dry and the ground is not mud. Move cars off the driveway if windows face it. Keep pets inside while ladders are up. Unlock side gates. Nothing else; the crew brings its own water and power.
While they work. Gutters first, glass last, as described above. Nobody needs to be home for exterior work; the crew does not come inside. If something cannot be reached safely (a pane over a sunroom roof, a gutter run behind a tree limb) the crew photographs it and tells you rather than guessing.
After. Photos of every gutter run and the finished glass, sent by text or email before the crew leaves. The invoice matches the number quoted on the phone.
Send a photo and we tell you what it is. No argument about whether it rained.
Streaks. Purified water dries clean; a streak means something was missed, and that is on us. Send us a photo of it and we tell you what it is.
Spots that come back. Round white spots that return a day after cleaning are mineral deposits from sprinklers or hard water etched into the glass, not dirt. Cleaning cannot remove them; a mineral treatment can. The crew flags it on the visit so you are not surprised.
Rain the next day. Rain is distilled water and does not dirty clean glass by itself; what spots glass after rain is dust already on the frame or screen washing down. That is why frames and screens are done, not just the pane. If it looks worse after a storm, send the photo and we look at it.
Overflow after a cleaning. If a gutter runs clean and still sheets water over the edge in the next rain, the cause is slope, a sagging hanger or an undersized downspout, not debris. The crew notes what it saw and tells you; cleaning it again will not fix it, and we will not sell you a second cleaning for a slope problem.
Your house. Ladder stand-offs on every ladder so nothing rests on the gutter lip or dents the siding. Screens go back in the window they came out of.
Neighborhood by neighborhood, with a lead time we say out loud, and a call before the truck turns in.
Our washing services cover gutters and exterior windows across Foster City and the neighborhoods around it, and the crew knows the lot sizes and roof lines that come up most often here. Window cleaning services start with an estimate: call (866) 435-6328 or text us the number of stories and a photo of the house front, and we will confirm the number and the date. Lead time depends on the season, and we will tell you the first open slot when you call instead of guessing from a calendar we do not control.
The two busy windows are the spring and the fall, because that is when leaves and rain dust hit the houses hardest. Booking early in those months gets you a slot without waiting. Between those windows the calendar opens up, and owners of condos on a once-a-year schedule can usually get in on short notice.
Nobody needs to be home for exterior work. Our crew works outside, does not come inside, and we call before we come so the arrival time is never a surprise. The gutters and downspouts get the first pass, the runoff drains away before the glass is touched, and every run is cleared down to the outlet. We haul the debris away with us rather than blowing it onto the lawn or into the next yard, and we remove dirt and grime from the sills and frames as part of the visit, not as an add-on.
Yes, and it is the same crew. Our two people do the roof blow-off, the gutters and the downspouts first, then the glass, so one visit covers both and nothing is cleaned twice.
We do not give a figure or a range here, and that holds for residential and commercial buildings alike. The number comes from the stories and the size of the building, and we give it by phone or text before anything is booked.
For most houses here, yes. Pollen, rain dust and sprinkler spots collect on the exterior panes, and regular cleanings in the spring and fall keep that grime from baking onto the glass.
Our Foster City customers mostly book in the spring and the fall, the two windows when the leaves come down hardest and the dust builds up fastest. Booking in either of those windows gets you a slot soonest.
No. We clean the gutters first and the glass last, so the grit and the black water that come off the gutters drain away before anyone touches the windows.
Screens are rinsed, sills are wiped, and the frames are done as part of the visit. We use purified water rather than cleaning solutions on the glass, so nothing is left behind to streak. Tracks are included on the exterior side as well, and we do not bill them as extras.
We clean exterior glass only on this visit. We do not do interior glass or pressure washing, so if you need those, tell us and we will point you to the right service.
You do not need to be home. Turn the sprinklers off the night before, move the cars off the driveway, keep pets inside while the ladders are up, and leave the side gate unlocked. Call (866) 435-6328 to book, or text us a photo of the roofline and we will confirm the visit.
Stories, rough window count, a photo of the front by text. That is a real number, not an appointment.
