Our own crew cleans gutters in Ontario, every downspout flushed and flow-tested, debris hauled away, and photos of every run before we leave so you can see the trough is clean. The price comes from the number of stories, the size of the house and how much tree cover sits over the roof. Give us those three things and the number we quote on the phone is the number on your invoice. Across California we have found that most of our customers book in the spring and fall, when the seed drop and the leaf drop have settled.
Quoted from stories, size and tree cover, over the phone, with nothing added once the crew is on the roof.
The price depends on how many stories the house has, its size and what is sitting in the gutters. Most Ontario homeowners ask for the number first, and we give it over the phone at (866) 435-6328 or by text. As a homeowner you only need to tell us those three things. The number we quote is the number we charge. Other gutter cleaning services price by the linear foot, and that lands in a similar place per run, though it hides what the crew actually finds on the roof.
What moves the quote on Ontario homes is usually a third story or a roof too steep to walk, a walk-out basement that puts the back run well up in the air, gutters nobody has opened in years, and guards we have to lift and reseat. A packed gutter system takes longer to clear than a light fall of leaves, and a single clog at the elbow adds time as well. A run that has been holding water for a season tells us where the drainage fails before we ever touch the ladder. Downspout flushing, flow testing and debris haul-off are part of the job and never billed as extras, and they leave the lawn clean. If anything changes the job we raise it before work starts, never on the invoice.
On our Ontario jobs the houses with heavy tree canopy show the most leaves and debris in the troughs, along with twig and needle litter. Clogged downspouts are where it usually starts, at the elbow. The landscape around a tree-heavy lot tells us a lot before the ladder goes up. On one recent Ontario job the run had seeds and grit packed to the elbow, and the water flow stopped well before the corner; once we cleared it and flushed the line until the water came out clean at the bottom, the water away from the foundation ran clean. That is the kind of find that shapes the quote, and why we ask about the trees before we give a number.
Where we see a sag, a leak at a seam or a run pulled loose from the fascia, we photograph it and note it in the report, but we do not treat it as part of the cleaning. Structural damage is not something we quote as a cleaning. The same three questions set the quote for commercial properties as for a house, so ask for the stories and the size either way. Ask for a photo of the front of the house by text if that makes it easier, and we will tell you what we see.
| One story | Two stories | Three stories or steep | |
|---|---|---|---|
| Under 1,500 sq ft | from $150 | from $225 | from $295 |
| 1,500 to 2,500 sq ft | from $200 | from $260 | from $335 |
| Over 2,500 sq ft | from $235 | from $305 | from $395 |
For context, nationally: Angi 2026, US average $168, most $119 to $234, $0.95 to $2.25 per linear foot.
Downspouts flushed and flow-tested, debris hauled, photos of every run. The quote already has all of it in.
Our crew clears every gutter run by hand, not just the stretch you can see from the driveway. Roof valleys and the area above the gutter line are blown clear first, so the next rain does not refill what was just emptied. Every downspout is flushed with water and watched until it runs clear at the bottom; one that will not clear is worked from the top where it can be reached. Where a downspout feeds an underground drain line, the crew checks that water is leaving at the outlet and tells you if it is not; clearing a buried line is a separate job and is quoted before anyone touches it.
Debris goes into bags and leaves with the truck. It is not blown onto the lawn, the deck or next door. The ground is left as it was found.
Before the crew leaves you get photos of every run and every downspout, before and after, on your phone, whether or not you were home. Anything the crew sees that is not a cleaning problem, a hanger pulled loose, a seam dripping, a run sitting flat, is photographed and reported, not repaired and not sold on the spot.
What can change the number, and you hear it before work starts, never on the invoice: a third story or a roof too steep to walk; gutters that have not been touched in years; guards that have to come off and go back on.
Twice a year for most houses: once after the spring seed and pollen drop, once after the last leaves fall.
Across California, our spring visit lands in mid to late June and our fall visit in late November to December. Ontario CA houses under heavy tree cover tend to need the spring and fall visits most. In spring we find seeds, seed casings and pollen paste packed in the elbows, the buildup we clear first. In fall it is the wet leaf mat, and on houses that skipped the fall visit we see runs that have sagged or pulled loose before the rains are over. A clean run at the start of the season saves a second trip.
Under heavy tree cover we see the clog build faster. Needles and grit pack the downspouts between visits, so those houses are on a three to four month rhythm. Houses with a heavy canopy book more cleanings, while residential properties with few or no trees do well once a year at the fall visit. Gutter guards still need the surface cleared, though less often, and a clean trough under the guard is the goal. A rainwater backup from one missed visit is easy to miss from the ground, which is why we suggest a rain gutter check after the first heavy rainfall of the season. Regular gutter cleaning keeps the water moving, and gutter maintenance between visits keeps the job simple.
When a gutter stops flowing we can usually see the blockage from the roofline in one pass, and the rest of the house tells us what else needs a look. Each visit gives us an estimate for the next one, and the schedule follows from what we find. After the first visit we tell you which tier your lot actually needs. We run the same schedule for residential and commercial buildings. If you are not sure when to clean your gutters, ask us on the first call, and ask about a debris removal visit if a storm has dropped more than the usual load.
Water over the edge rots the board behind the gutter first. Everything after that is slow, and slow is what a policy excludes.
The three signs. Water pouring over the front edge in rain instead of out of the downspout. A run that sags, sits low or has pulled away from the fascia. Plants growing out of the trough. Any one of them means the gutter is full.
What happens next. Water that cannot drain sits in the trough and spills behind it. The fascia board rots, then the soffit. Water backs up under the first course of shingles and shows up as a ceiling stain. Siding stains and swells. Below, the overflow cuts a channel at the foundation and finds the basement. The wet debris itself weighs enough to pull the gutter off the house. Standing water breeds mosquitoes; dry debris houses wasps. Where winters freeze, the trapped water becomes an ice dam at the eave and lifts the shingles from underneath.
Why your policy will not pay. Homeowners insurance generally does not cover water damage traced to clogged gutters. Carriers class gutter cleaning as routine maintenance, and damage from skipped maintenance as preventable neglect, which a standard policy excludes. A limb that tears a gutter off in a storm is sudden and accidental and is usually covered; a fascia board that rotted over two years is not. This is general information, not insurance advice; read your policy or ask your agent.
Guards stop leaves. They do not stop needles, seeds, grit or the paste they turn into. The job gets shorter, not gone.
Yes, guarded gutters still need cleaning, less often, and it is a different job: clearing what sits on top of the guard and checking that water is actually getting in, rather than scooping out the trough. Mesh and screen guards hold whole leaves off. Pine needles thread through, seed casings and pollen mat on top, roof grit settles underneath, and once that mat is wet, rain runs over it and off the front edge. The gutter is empty and the water never went in.
Guards earn their keep under big leafy trees and on roofs too high to want to climb. They do not end maintenance, whatever the installer said. Our crew lifts the panels, clears underneath, flushes the downspouts and reseats the guards; tell us what is on the house when you get the quote and it is priced as a guarded system, which usually runs shorter than an open one.
Under an hour on most houses. Nobody has to be there, and the photos arrive either way.
The crew calls the day before with an arrival window and again when they are on the way. This Old House puts a professional gutter cleaning at 30 minutes to an hour on a typical home; bigger houses, steep roofs and gutters left for years run longer. Nobody needs to be home for exterior work; the crew does not come inside. Before they arrive: side gate unlocked, cars off the driveway if runs face it, pets inside while ladders are up. Ladder stand-offs keep the ladder off the gutter lip and the siding. After: photos of every run and downspout before the truck leaves, and an invoice that matches the quote.
Send us a photo or a short video in the rain. You hear what it is before anyone talks about money.
Still overflowing. A gutter that is clean and still sheets water over the edge in rain has a slope, capacity or downspout-size problem, not a debris problem. If that happens after a cleaning, send us a photo or a short video of it in the rain and we tell you what it actually is; we do not sell a second cleaning for a slope problem.
The number. The price quoted on the phone is the price on the invoice. If the crew finds something that changes the job, you hear it and agree to it before they start, never after.
Your house. Stand-offs on every ladder so nothing rests on the gutter lip, and screens and downspout extensions go back where they were.
Payment. The balance is charged when the job is finished and the photos are on your phone. Some dates take a small booking fee to hold the slot, and you hear about it before you book.
The whole city and the towns around it, booked by phone or text from the nearest crew.
We have cleaned gutters and downspouts across Ontario and the surrounding areas, and Ontario gutter cleaning is dispatched from the nearest of our bases. Describe your street and the house, and the crew knows what the typical house on that street looks like. Booking is simple: you call (866) 435-6328 or text a photo of the front of the house, give us the stories, the size and whether trees hang over the roof, and we quote the number that will be on the invoice. Lead time depends on the week, so we confirm a date when you call. Our calendar fills in the two busy windows of spring and fall, so those are the times to book early.
We call before we come, and nobody needs to be home for the visit. Our gutter services are scheduled around your week, and we keep the ladders out of your way. Keep your gutters clear between visits and you protect your home from water damage and keep the foundation dry. We also flush every downspout on every visit, because a clean run that drains into a clogged line is no help at all. A small leak at a joint is easy to miss from the ground, so we point it out when we see one. Clear gutters keep heavy rainfall moving away from your home.
The cost for a two-story house across Ontario comes from the stories and the size of the house. Our cleaning services in Ontario all follow the same gutter cleaning process, so we give the number over the phone or by text, and it is the number you pay.
Across California our visits land in mid to late June and late November to December, after the seed drop or after the leaves have come down. Waiting past those windows usually means a packed trough and a longer visit.
Most slots come up within the week, and we confirm the date when you call. We do not promise same-day service unless the calendar has an open slot that day. If you want to get your gutters done before the rains, call early.
Yes. We flush every downspout and check where it drains, including underground lines where we can see the outlet. Clogged downspouts get flushed from the top until they run clear, and a landscape that drops needles and seeds at the elbow gets checked on every visit. Cleaning and maintenance go together on every visit, so gutter maintenance gets checked with the cleaning. Clearing a buried line is a separate job, quoted before anyone touches it.
Yes, a guarded gutter system still needs cleaning, though less often. Under guards we find the grit and the seed casings that sit on top, and we clear them until the trough is clean and check that water is getting in.
If the gutter is clean and still overflows, that is a slope or downspout size problem rather than debris. Photograph the run and any fascia that looks soft or starting to rot, and text it to us during rain; we will say plainly what it is, with no second cleaning sold on top.
The price does not change once the crew is up the ladder unless something we could not see from the ground changes the job. If it does, you hear it and agree to it before work starts.
Stories, size and a photo of the front by text. That is a real number, not an appointment.
