What Gutter and Window Cleaning Costs in Islip

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 window cleaning services by the number of stories and the approximate window count. Booking the gutters and the exterior glass in one visit costs less than booking the two jobs separately, and the number we give on the phone is the number on the invoice. The washing services on the quote cover both the gutters and the window washing, so nothing gets added at the end.

On the day, the crew finds what moves the quote: a third story or a roof too steep to walk, a large number of window panes or oversized picture windows, gutters that have not been opened in years or are packed with needles and leaves, a layer of grime on the glass that has built up for years, gutter guards that have to be lifted and reseated, and hard-water spotting from a sprinkler line that no cleaning removes. Quotes cover the exterior only, so a request for interior and exterior glass gets its own price. Downspout flushing, screen rinsing and sill wiping are part of the job and are not billed as extras.

Getting the exact number is simple. Send us the number of stories, your approximate window count and a photo of the front of the house by text, and we will give you a price before anyone climbs a ladder. Call (866) 435-6328 if you would rather talk it through. If you have a sense of how many regular cleanings a year you need, tell us that too, since a house on a schedule is easier to plan around than one called in after a problem. Our crew will confirm the window count from the ground, and any difference is discussed before the work starts, not after.

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.

Why We Do the Gutters Before the Windows, Every Time

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.

What's Included in the Price

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.

When to Book Gutter and Window Cleaning in Islip

Twice a year for both, and the same two months, which is why one visit covers it.

Most of our customers here book window and gutter work twice a year, in late spring and in fall, which is why one crew in one visit makes sense for the calendar.

In spring we find pollen on south-facing glass and pollen paste packed in the gutters, and our cleaning solutions are chosen for the film each season leaves behind. In fall it is the leaf load, and on houses that skipped the fall visit we see gutter runs that sagged under the weight of wet debris. Clogged gutters are the early warning, and water damage at the fascia is what follows if they go too long. Across New York, leaf timing and seasonal grit affect residential and commercial buildings alike. Storm and wind seasons can move these dates, so we confirm the timing with you before we book the crew.

Some houses need a third visit. If heavy tree cover hangs over the roof, needles and grit pack the downspouts between visits. If a sprinkler line hits the glass, the spots come back a day after cleaning. A house near a busy road or a construction site collects more film on the glass than the same house in a quiet street, and those are the ones we put on a shorter schedule. Multi-story buildings take longer on the ladder, so the stories count sets the length of the visit.

Cleaning windows inside the house is not part of this schedule. The haze you notice from the sofa is almost always the outside of the glass, and that is what we clean. You know the windows need attention when you see a haze that only shows up when the sun is low. You know the gutters need attention when water sheets over the edge during rain instead of running into the downspout.

How Long It Takes and What to Do Before We Come

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.

If It Streaks, Spots, or Overflows After We Leave

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.

Where We Work Around Islip

Neighborhood by neighborhood, with a lead time we say out loud, and a call before the truck turns in.

Our crew works across Islip, and we book by phone or text. Call (866) 435-6328 or send the number of stories and a photo of the house front, and we will tell you when a slot opens. Most estimates turn into a booked date within the lead time shown on our calendar, and the busy weeks in spring and fall fill first, so it helps to ask early.

Nobody needs to be home for exterior work. We call before we come, and the crew does not enter the house. If you need to schedule service around a school run or a shift at work, tell us when you book and we will plan the arrival window around it. The crew checks every window from the ground, sill to top, before the ladder goes up. Clean glass and clear gutters do a lot for curb appeal from the street, which is one reason we keep the two jobs on one calendar.

We are a crew that does gutter cleaning and exterior window cleaning as one job, so the same people who clean the gutters are the window cleaners who do the glass. Our professional window cleaning runs from the same truck as the gutter work, which keeps the visit to one arrival. The window cleaning services and the gutters share one quote, and our cleaning services stay on one invoice. If you already have a regular service on the property, we can schedule around it so the two do not overlap.

Frequently asked questions about window and gutter cleaning in Islip

Do window cleaners also clean gutters, and is it the same crew?

Yes. For a residential property, the same two people clean the gutters and the outside of the windows in one visit. We start with the gutters and finish with the glass, so nothing dirty washes onto clean panes.

What does it cost to clean the gutters and windows on a two-story house in Islip?

The number comes from the stories and the window count, whether it is a house or one of the condos. Send us both by phone or text, along with a photo of the front, and we give you the number before we book.

Is it worth having the outside of the windows cleaned if the inside stays as is?

On a residential window, the outside carries dust, rain film and sprinkler spots that you do not see from indoors. Cleaning the outside gives you a clear view and stops those deposits from building up on the frames.

When should I book gutter and window cleaning in Islip?

Most of our customers here book in late spring and in fall. We confirm the exact timing with you based on the leaf load and the film on the glass.

Will dirty gutter water end up on the clean glass?

No. We clean the gutters and downspouts first and the glass last, so runoff and debris from the gutters never land on panes we have already cleaned. That is the reason the order matters.

Do you clean screens, sills and tracks, or are those extras?

Screens are rinsed to remove dirt, and sills are wiped as part of the job. Tracks are included in the visit as well, and nothing is billed as an add-on for them.

Do you clean inside the windows or do pressure washing?

On this visit we clean the exterior glass only. We do not clean inside the windows or do pressure washing on this visit.

Do I need to be home, and what should I do before the crew arrives?

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 the ladders are up, and leave the side gate unlocked.
