Two August 2026 jobs where the debris was not the problem
Quick answer: In late August 2026 DT Cleaning ran two eavestrough jobs on opposite sides of Toronto. In Scarborough the client wanted the clogging to stop for good, so the system was cleaned and then fitted with Leaf Guard Protect. In Etobicoke a straightforward full clean billed $240. On both houses the debris was the routine part of the visit. What mattered was the fault underneath it that no amount of cleaning would have corrected.
Neither homeowner had called about a leak, a slope or a blocked pipe. One called because the gutters kept filling up, the other because it was time. Both jobs found a defect that a cleaning alone would not have fixed and that nobody could see from the ground. That is the ordinary case, not the unusual one, and it is the reason a proper visit ends with water rather than with a look.
Eavestrough cleaning in Scarborough: four failed seams under the debris
Quick answer: On the Scarborough house in August 2026 the crew found 4 separate points where the sealant had failed, spread across the system rather than clustered in one corner. All 4 were stripped and resealed the same day, and the whole house was resealed rather than just the leaking joints. None of it was billed, because the repairs were found during work the client had already paid for.
This client's complaint was simple: the eavestroughs kept clogging and the cleaning bill kept coming back. Guards were the answer, but guards never go onto a dirty or leaking system. Anything left in the trough gets sealed under the panels where nobody looks at it again for years, so the system was cleaned end to end first and then inspected properly.
With the trough empty the joints became visible for the first time. Four of them had sealant that had given up. On an aluminum eavestrough the corner miters and the end caps carry the load, and once the bead cracks the water leaves through the joint instead of the downspout. The fix is not a smear over the old material, it is cleaning the joint back and rebedding it.
The one section sitting out of level, and why cleaning would never have fixed it
Quick answer: One run on the same Scarborough house in August 2026 was pitched wrong, so water stood in it instead of moving to the outlet. Standing water is the reason that run held debris longer than the rest of the system. It was brought back to level on the spot at no charge, before a single guard panel went down, because a guard over a flat run only hides the puddle.
A trough needs a fall towards the outlet. When a section sits level or pitches backwards, water stops moving, silt drops out of it, and the debris that a straight run would have carried away stays put and composts. The client experiences that as one part of the house always clogging first, and reasonably concludes they need more frequent cleaning.
More frequent cleaning would not have fixed it. The slope would. This is the fault that most often gets cleaned around for years instead of corrected, and it is only visible when the trough is empty and someone puts a level on it or runs water through it.
"Before we install anything, we clean the system out completely and check what is underneath. On this house we found four places where the silicone was leaking, so we redid the sealant on the whole house, and one section was out of level, so we corrected it on the spot. Both of those were free. Then the guards went on."

A $240 Etobicoke clean and a downspout blocked in the middle of the pipe
Quick answer: The Etobicoke job in August 2026 billed $240 for a full eavestrough cleaning. The house sits under a mature blue spruce, so the troughs were carrying needles rather than leaves. Several runs were awkward to reach and were cleared with an extension pole. After the troughs were clean, a hose test found one downspout blocked mid-pipe, with nothing visible from the top opening or the bottom outlet.
Conifer debris behaves differently from leaf litter. Needles are small, they travel further into the system, and they pack rather than mat, which means they can move down a downspout and then wedge partway along it. A leaf jam usually shows itself at the top opening. A needle jam can sit in a closed section of pipe where neither end tells you anything.
The downspout came off the wall, the blockage was cleared by hand, the pipe went back on, and it was flushed a second time to confirm it ran. The client was shown the before and after photographs at the end of the visit, which is standard on every DT Cleaning job.
Why a hose test finds what looking down the pipe cannot
Quick answer: Every downspout on both August 2026 houses was flushed with a hose rather than inspected by eye. A visual check confirms the opening is clear and tells you nothing about the closed length of pipe running below it to the ground. On the Etobicoke house 1 of the downspouts backed up under water when it had looked completely normal from above.
This is the step most often skipped, because it takes longer and because the trough already looks finished. A downspout is a sealed pipe from the outlet to the ground. Light gets in at the top and at the bottom. A blockage sitting between the two is invisible from both, and the only thing that reports it is water refusing to come out the far end.
Why finding a blocked downspout in August matters more than finding it in January
Quick answer: A blocked downspout holds water inside the pipe. Toronto crosses the freezing mark repeatedly through winter, and each freeze expands whatever is trapped in that closed section. That is what splits seams and pulls brackets off a wall. The Etobicoke blockage was found in August 2026, months before the first freeze, which is the difference between a hose test and a repair bill.
The city treats this as a drainage problem rather than a cosmetic one. The City of Toronto's basement flooding guidance lists blocked eavestroughs alongside sewer backups, and its mandatory downspout disconnection program exists because roof water pushed into an overloaded sewer raises the flooding risk for a whole street.
The freeze-thaw pattern behind the damage is not folklore. The Canadian Climate Normals published by Environment and Climate Change Canada record how often this region crosses zero through the winter months. Water sitting in a sealed pipe does that crossing with it.
What these two jobs cost
Quick answer: The Etobicoke full clean billed $240 in August 2026, including every downspout flushed and one downspout taken apart and cleared. On the Scarborough job the 4 sealant repairs and the slope correction were not billed at all, because they were found during work the client had already booked. Guard installation is quoted separately by the linear foot.
| Job, August 2026 | What it included | Billed |
|---|---|---|
| Etobicoke, full eavestrough clean | Whole system cleared, extension pole on the awkward runs, every downspout hose-tested, one downspout disassembled and cleared | $240 |
| Scarborough, repairs during the visit | 4 failed sealant joints stripped and rebedded, whole house resealed, one section brought back to level | No charge |
| Scarborough, Leaf Guard Protect | Full clean first, then guards installed over the cleaned system, 5-year warranty | Quoted per linear foot |
The reason the Scarborough repairs were free is not generosity, it is sequence. The ladders were already up and the trough was already empty. Charging separately for a fault found during work the client had booked anyway would mean charging twice for the same climb.
When to book, and why the calendar is the wrong guide
Quick answer: Most Toronto homes need 2 cleanings a year, one in late spring after the seed pods drop and one in late fall once the leaves are down. Houses under conifers are the exception. The Etobicoke house needed a proper flush in August 2026 because a spruce sheds through all 12 months rather than in a single window.
Timing follows the trees on your lot, not a date. Toronto's yard waste collection schedule is a reasonable proxy for when the leaf drop finishes in your neighbourhood, and the right visit is after it rather than during it. Book during it and you pay to clear a trough that fills again the following week.

Frequently asked questions
How much does eavestrough cleaning in Scarborough cost?
A bungalow with 40 to 60 feet of trough runs $130 to $200, and a two-storey detached home with 80 to 120 feet runs $200 to $350. The Etobicoke house described here billed $240 in August 2026 for a full clean with every downspout flushed. Prices are flat rate and confirmed after a photo or video review, not billed by the hour.
How do I know if my downspout is blocked?
You often cannot tell by looking. A downspout is a closed pipe, so a blockage sitting partway along it is invisible from the top opening and from the outlet at the bottom. The reliable test is water: run a hose into the trough and confirm it comes out the far end at full flow. On the Etobicoke job in August 2026 the blocked downspout looked completely normal from above.
Do you charge extra for clearing a blocked downspout?
No. Flushing every downspout is part of a standard eavestrough cleaning, and taking one apart to clear a blockage during that visit is included. On the Etobicoke house one downspout was removed from the wall, cleared, refitted and flushed again, all inside the $240 clean.
What do you do if you find a leaking joint during a cleaning?
We reseal it during the same visit at no charge. On the Scarborough house in August 2026 four sealant joints had failed, and the whole house was resealed rather than only the four leaking points. The ladders were already up and the trough was already empty, so charging separately would mean charging twice for the same climb.
Why does one section of my gutter always clog first?
Usually because that run is not pitched correctly. A trough needs a fall towards the outlet. A section sitting level or pitched backwards holds standing water, silt drops out of it, and debris that a correctly sloped run would have carried away stays and composts. More frequent cleaning does not fix it. Correcting the slope does.
Do gutter guards mean I never need cleaning again?
No. Guards stretch the interval, they do not remove maintenance. Fine debris still works through over time, so we recommend a light check every two to three years instead of the usual twice a year. The honest way to compare guards against cleaning is annual cost over several years, not one invoice against another.
Can gutter guards be installed on a system that leaks?
They should not be. Panels seal in whatever is underneath, including a cracked joint or a flat run holding water, and nobody looks under them again for years. On the Scarborough house the system was cleaned, four seams were resealed and one section was brought back to level before any guard went down.
What warranty comes with a Leaf Guard Protect installation?
Five years. The Scarborough installation in August 2026 carries a five-year warranty, and the cleaning, resealing and slope correction that preceded it were done at no charge as part of preparing the system.
How often should eavestroughs be cleaned in Toronto?
Twice a year for most homes, once in late spring after the seed pods drop and once in late fall once the leaves are down. Houses under conifers need a different schedule, because a spruce or pine sheds through the whole year rather than in one window. The Etobicoke house in this article sits under a mature blue spruce and needed a flush in August.
Why is a blocked downspout worse in winter?
Because it holds water inside a sealed pipe. Toronto crosses the freezing mark repeatedly through the winter, and each freeze expands whatever is trapped in that closed section. That pressure splits seams and pulls brackets away from the wall. Finding the blockage in August rather than January is the difference between a hose test and a repair bill.
Are your crews insured and certified?
Yes. Every DT Cleaning technician is Working at Heights certified, and the company carries $2 million Commercial General Liability insurance with full WSIB coverage on every job. We have served Toronto and the GTA since 2023 and hold 500+ five-star Google reviews.
Do you send photos of the work?
Yes. Every job includes before and after photographs, and on the Etobicoke visit the client was walked through them at the end of the appointment. The photographs in this article come from those two August 2026 jobs.
Tired of the same section clogging every year?
DT Cleaning clears the whole system, flushes every downspout with water rather than checking it by eye, and reseals or re-levels what we find while the ladders are already up. Scarborough, Etobicoke and the rest of the GTA.
