Yes, the same two people clean your gutters and the outside of your windows in one visit. We clear the gutters first and do the glass last, so nothing runs back onto clean panes. We price the job by the number of stories and the approximate window count, and doing both in one visit costs less than booking two separate trips. Most of our Gaithersburg customers book this in the spring and fall, and we keep the same order of work on every house.
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 window count. Doing both jobs in one visit costs less than booking them separately, and the number we give you on the phone is the number we charge. Downspout flushing, screen rinsing and sill wiping are part of the job and are not billed as extras. Our quote covers exterior glass only, so there is no interior and exterior line on the invoice.
On our jobs, the things that move a quote are the same ones every time. A third story or a steep roof means a boom or scissor lift and more time on the ladder, and multi-story buildings with a lot of glass take the longest. Oversized panes and a high window count add time to the glass. The gutters and downspouts that have not been opened in years, packed with needles and leaves, take longer to clear, and clogged gutters add time even when the glass goes quickly. Gutter guards that have to be lifted and reseated add time. Hard-water spotting from a sprinkler line hitting the glass is something no cleaning removes, so we flag it on the visit instead of pretending a wipe will fix it. Separate cleaning solutions for hard-water spots are a treatment we quote after the crew sees the glass. Window washing and the washing services that go with it are priced the same way: we look at the house first, then give you one number.
For professional window cleaning, the question we ask most often is how much glass sits above the reach of a pole, because that decides how long the crew stays on the house. Picture windows and tall sidelights count as separate panes, not a single line, so tell us about them when you call, and mention any residential window that sits above the reach of the pole. Most of our customers get a firm number the same day they ask, from a short phone call or a text with the number of stories and a photo of the front of the house. The grime on glass that has sat through a full season of pollen costs more time than a light film, and we say so before we start. Customers on regular cleanings keep the same crew and the same notes from the last visit, so the next number is easy to predict.
On our Gaithersburg jobs, one house we cleaned had three stories, a steep front roof, and a gutter run that had not been opened in several years. The customer called about the glass and asked us to look at the gutters while we were there. Once the crew saw the packed downspouts and the back run, the quote moved up because the gutters took most of the morning, not the windows. The number we gave on the phone was the number on the invoice, and the photos of each run came before the crew left. Ask us for the same kind of breakdown on your house: stories, window count, and a photo of the front.
| Gutters only | Exterior windows only | Both in one visit | |
|---|---|---|---|
| One story | from $150 | from $170 | from $275 |
| Two stories | from $225 | from $240 | from $375 |
| Three stories | from $295 | from $330 | from $495 |
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.
Across Maryland most customers book window and gutter cleaning twice a year, and regular cleanings in the spring and the fall keep both on the same calendar. On our Gaithersburg jobs the spring visit lands after the seed drop, and the fall visit lands after the leaves are down and before the first hard freeze.
What we find at each visit follows the calendar. In the spring month the south-facing glass carries a yellow film, and the downspout elbows are packed with pollen paste that turns to mud when it rains. In the leaf month clogged gutters hold a wet mat that backs water over the edge, and the glass under it is streaked with runoff, and a run that stays wet is where water damage shows up first. Storm and wind seasons move the dates a little, usually as a week or two either way, and we book around the weather rather than around a fixed date.
Some houses need a third visit. Heavy tree cover over the roof keeps the gutters packed between visits, so those customers are on every three to four months. Multi-story buildings under the same tree cover get the same schedule. A sprinkler line that hits the glass leaves round spots that come back a day after cleaning, and those houses need a mineral treatment on top of the regular cleaning. A house near a busy road or a construction site picks up a fine film faster than the average house, and we add a visit for those as well.
On our Gaithersburg jobs we see two customer patterns. One house with no large trees and an open lot is on twice a year, and that is enough to keep the gutters flowing and the glass clear. A second house under mature trees, with a sprinkler line hitting the front windows, is on three or four visits a year. Both get photos of every run and every pane after each visit, and the crew tells you which pattern your house matches on the first visit.
You can tell the windows need attention when you see a haze that only shows when the sun is low. You can tell the gutters need attention when water sheets over the edge in the rain instead of running down the downspouts. Waiting only means more grit to remove dirt from, and a clogged run is where water damage starts at the fascia.
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.
On our Gaithersburg jobs we have cleaned residential properties close to the tree line, where the gutters take the most work, and we keep a crew close enough to reach every part of Gaithersburg without a long drive. Our window cleaners handle professional window cleaning from the outside only, and our cleaning services stop at the exterior, so the crew arrives with the pole, the purified water and the boom or scissor lift for the taller houses. Each residential window on the outside of the house is reached from the pole or the lift.
Booking is simple. Call (866) 435-6328 or text a photo of the front of the house with the number of stories, and we give you a firm quote the same day you ask. Lead time depends on the calendar at the time you call, and we tell you the next open date on that call. The two busy windows of the year are the spring month and the fall leaf month, when our calendar fills first, so a booking made early in those months keeps its date.
Nobody needs to be home for exterior work, and our crew calls before they come, so you know when the truck will pull up. The schedule service runs on a date you pick, and we keep the same crew on the same house so the next visit starts from the notes of the last one. Every window on the outside of the house gets the same treatment, and every sill gets wiped on the way out, so the glass and the frame come out even. Clean glass and clear gutters do a lot for curb appeal, and that is the part most owners notice from the street.
Yes, on our jobs the same two people do both, and they do it in one visit. We clear the gutters and downspouts first and do the glass last, so nothing from the gutters washes back onto clean panes. For condos, tell us when you call whether the gutters are yours or shared, because that changes the plan before the crew comes.
We give the number from the stories and the size of the house, including multi-story buildings with more glass. Text a photo of the front of the house with the number of stories, or call (866) 435-6328, and we quote it from there. Quotes for residential and commercial jobs are given on the call, so say which one you have.
On our Gaithersburg jobs the outside carries most of the dust, rain spotting and sprinkler spots, so the outside is where the haze comes from. The windows inside can stay as they are, and the outside still needs its visit.
Most of our Gaithersburg customers book in the spring and the fall, after the spring growth settles and after the leaves are down. Booking early in those months keeps your date, and regular cleanings get the same crew each time.
No, because we do gutters first and glass last. When the glass gets washed first, the runoff from the gutters streaks it again, which is why the order matters. Flushing each downspout is how we remove dirt before the glass is touched.
Screens are rinsed and put back on request, sills are wiped, and frames are done as part of the job. Tracks are included in the outside work when they are reachable from the outside.
We clean the outside of the glass only on this visit, so interior and exterior work is never bundled into one number. We do not clean inside the windows and we do not do pressure washing.
You do not need to be home. Turn the sprinklers off the night before, move cars off the driveway if windows face it, keep pets inside while ladders are up, and leave the side gate unlocked.
Stories, rough window count, a photo of the front by text. That is a real number, not an appointment.
