Yes, the same two people do our window cleaning services and your gutters in one visit, gutters first and glass last. We price it by the number of stories and the approximate window count, and both jobs done together cost less than booking them as two separate trips. Across Maryland, most of our customers book this in the spring and in the fall. Call (866) 435-6328 and we will give you a number from your stories and window count.
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.
Our washing services are priced by the number of stories and the approximate window count, and window washing done with gutter cleaning in one visit costs less than booking them as two separate jobs. The number we give on the phone is the number we charge, so tell us the stories and the window count and we will say the figure before anyone climbs a ladder.
On our jobs, the things that move a quote are consistent. A third story or a roof too steep to walk takes more time on the ladder. Oversized panes and a high window count add to the glass, and grime that has built up for years takes longer than a light film. Gutters that have not been cleaned in years, or that are packed with needles and leaves, take longer to clear. Gutter guards have to be lifted and reseated before we can reach the run underneath. Hard-water spotting from sprinklers is a separate issue that a normal cleaning does not remove, and we will tell you about it on the visit. Clearing the gutters and downspouts, rinsing screens and wiping sills are part of the job, not extras billed later.
Here is what we have found on our North Potomac work. Most of the cost difference between two houses comes down to how many stories there are and how much glass sits above the first floor, and when a house has tree cover over the roof, the gutters fill faster and the run takes longer. Condos and townhouse rows with shared roof lines are quoted per building, not per unit, so the crew sees the whole roofline and the runoff path before giving a number. A crew can usually remove dirt from a lightly soiled run quickly, but a full house with heavy buildup takes longer. The fastest way to get an exact figure is to text us a photo of the front of the house and tell us how many stories it has.
| 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 of our customers book window and gutter cleaning twice a year, in the spring and again in the fall, and one crew in one visit keeps those regular cleanings simple. On our North Potomac jobs the pattern holds for most houses, so the fall visit lands after the last leaves come down and the spring visit comes once the pollen season has settled.
What we find at each visit is predictable. In the spring, a film forms on south-facing glass and a paste in the gutters, and the downspout elbows are packed with seed and grit. In the fall the leaf load is heavy, and it sits wet in the gutters until the first cold snaps. Storm and wind seasons can move the dates, and a hard summer thunderstorm can leave the gutters full of debris that was not there a month before. Our crew does not use cleaning solutions on the glass, only purified water.
Some houses need more cleanings than the usual pair. Heavy tree cover over the roof keeps the gutters loaded through the summer, and a sprinkler line that hits the glass leaves spots that come back a day after cleaning. A house near a busy road or a construction site picks up a film that builds faster than normal. The same schedule logic applies to residential and commercial buildings, though a commercial site is quoted on its own. When we see any of these, we tell you what we found and suggest the visit schedule that fits the house, but the decision is yours.
Two signs tell you the windows need a visit: haze you only notice when the sun is low, and the film that shows up on the glass after a few weeks of spring weather. Large picture windows are usually where the haze shows first. Two signs tell you the gutters need one too: water sheeting over the edge of the run during rain, and the sound of water running behind the fascia instead of into the downspout. This visit covers exterior glass only, so interior and exterior work is a separate booking.
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.
We provide professional window cleaning on the residential streets of North Potomac, and we are happy to give a quote for any house in the area. To schedule service, call (866) 435-6328 or text us the number of stories and a photo of the front of the house, and we come back with a number and a date. Our typical lead time depends on the calendar, and we will tell you the first open slot when you call.
The two busy windows of the year are the spring season and the fall leaf drop, and our calendar fills during both. Clogged gutters are often the reason a fall call comes in early, and a clogged run that overflows is one of the first ways water damage starts at the fascia. If you want a particular week, book early. We also do residential gutter cleaning for homeowners on the same visit when a house needs it, and we handle commercial properties and multi-story buildings as the same kind of crew on a per-building basis. Clean glass and clear gutters both add to curb appeal, and both show from the street. We call before we come, so you know the day and the window.
Nobody needs to be home for exterior work. Our crew does not come inside, so windows inside are never part of the visit, and the photos of every gutter run and the finished glass go to your phone before we leave. Our cleaning services are built around the same routine on every job, which is why the work reads the same from one house to the next.
Yes, the same crew cleans the gutters and each residential window on one visit, so you get one schedule and one bill. The gutters are cleared first and the glass is done last, so nothing falls back onto clean windows.
The number comes from the stories and the approximate window count, and we give it by phone or text before the visit. We do not quote it on this page because each house is different.
For most houses here, yes. Every window carries the spring film, the rain dust and the sprinkler spots, and those sit on the glass whether or not the inside is clean.
Our customers here book in the spring and the fall, which is when the pollen and the leaf load are heaviest. The same spring and fall pattern holds for residential properties across Maryland.
Not on our visits, because we clear the gutters and flush the downspouts first, let the wall dry, and only then start on the glass. That order is the whole reason both jobs go to one crew.
Screens are rinsed and sill wiping is included on exterior work. Tracks are cleaned on the visit when they can be reached from the outside.
No, this visit is exterior glass only. We do not clean inside the windows or do pressure washing on this visit, and we say so before we start.
You do not need to be home. Turn the sprinklers off the night before, move cars off the driveway, keep pets inside while the 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.
