Sewer lines cleared and filmed, and the gutters, downpipes and pits cleared too, because on this edge of the suburb they fill faster than anywhere else.

Does it only happen when it rains? That single question sorts almost every drainage call on this side of the suburb into one of two entirely different jobs.
If the answer is no, it is the sewer. Fixtures inside the house behaving badly regardless of the weather, and the causes are the ordinary ones: wipes, fat and hair. A cable through an access point deals with it and the camera afterwards says whether anything down there caused it.
If the answer is yes, it is almost certainly leaf load. A property against bushland collects an amount of leaf litter that inland suburbs simply do not have to deal with, and it accumulates in exactly three places: the gutters, the downpipes and the stormwater pits. Once a pit packs down it stops taking water long before it looks full.
That version matters more than people expect, because of where the water goes instead. Water coming over the front of a gutter lands against the wall and goes into the ground beside the building, every time it rains hard. That is drainage rather than weather, and it is worth treating as such.
Then say so first. It moves the whole visit from inside the house to the outside of it.
A sewer blockage does not care whether it is raining. Something is in the line, it was there yesterday, and it will still be there once the sky clears. A fixture that is slow on a dry Tuesday has an obstruction in it, and clearing that is the whole job.
Trouble that only turns up in a real downpour and settles once the rain eases is usually the stormwater side rather than the sewer, and on a property under this much canopy that almost always means something is loaded with leaf litter. Tell us which one it is when you ring, because the two get different equipment off the van.
It is worth being specific about it. Heavy for ten minutes and gone is different from two days of steady rain, and a property that only misbehaves in the second case is telling you the ground around it is already full rather than that anything is broken.
The gutters, the downpipes below them, and the stormwater pits in the ground. All three fill faster on this side of Hornsby than they do on an open block further in, and they fill in roughly that order.
Clearing the gutters and stopping there is the common half job. Litter that has already washed down sits at the bend at the foot of the downpipe, where nobody can see it and a garden hose will not shift it.
The pits are the ones that get forgotten, because they are in the ground and they look after themselves right up until they do not. If you have not had the grates off in two years, that is where to start.
Pennant Hills sits on a shale-capped ridge that carries tall forest, and the gullies running east towards Devlins Creek and the Lane Cove valley keep that tree cover more or less unbroken. It is most of why people move here and all of why the drainage needs attention.
A mature blue gum or angophora drops a genuinely surprising volume over twelve months, and not only in autumn. It is not a tidiness problem. It is a real load arriving on a roof that was sized for a much lighter one.
Lift the grate on a stormwater pit and it can look perfectly serviceable while passing almost nothing. Once leaf litter has wetted and packed down it behaves like a mat rather than a loose pile.
So pits are worth clearing on a schedule instead of on appearance. Once a year, before the wet months rather than during them, and it is the cheapest thing on this page by a wide margin.
The other reason to do it early is that a pit which has stopped passing water sends it somewhere else, and the somewhere else is usually across a path or against a wall. By the time you can see the consequence, the cause has been building for a season.
Ground that drops away towards a gully sheds water quickly, so properties on those streets rarely sit in it. The trade is speed. Water moving fast carries litter along with it and packs it hard into the first restriction it meets.
Which is why the failure here is rarely a flat line silting up over years. It is sudden, in a real event, at a pit or a bend that had been quietly filling for two seasons with nobody looking at it.
It also means the access points on these blocks are frequently well below the house, at the low corner near the boundary. Knowing where yours is saves us walking the property before we can start.
A gutter that cannot take what the roof is delivering does not spill evenly along its length. It goes over the front edge in sheets, into the ground beside the building, in the same spot every time.
Repeated often enough that is what becomes damp, movement and a subfloor smell. It is the reason a blocked gutter counts as a drainage problem rather than a wet afternoon.
Downpipe capacity is the usual culprit rather than the gutter itself. A roof this size under trees this size needs the outlets kept clear more often than a builder ever assumed, and adding one more outlet is sometimes the whole fix.
Wipes are still the largest single cause of what we cut out of house drains, whatever the packet claims about flushability. They stay intact, they catch on anything slightly out of line, and they hold everything that arrives behind them.
Kitchen fat is the slow version of the same story. It cools on the pipe wall, narrows the line a fraction at a time, then starts collecting whatever comes past. A drain that has been getting gradually worse for a year is usually this rather than an object.
Neither is a moral failing and neither is unusual. They are simply the two things that reliably turn a working drain into a slow one, and both are cheaper to deal with while the line is still moving.
The older housing here drains through clay lines with a joint every metre or so, and a mature tree will put roots through a joint that has already moved. They do not break sound pipe. They find an opening that was there first.
If a drain has blocked more than twice in a year, that is a defect describing itself, and it is worth filming rather than clearing a third time. Footage of a clear pipe is as useful an answer as footage of a fault, and it is the one that saves you money.
Where the camera does find an open joint, it can usually be repaired from the inside with a liner instead of opening the ground. On a block planted like these that matters more than the difference in price.

Water going over the front of a gutter in a downpour usually means the gutter or the downpipe below it cannot take the flow, and on a property carrying a heavy leaf load that is nearly always because something is packed with leaf litter rather than because anything has failed.
Because of where the water goes instead. Overshooting a gutter puts roof water straight down the wall and into the ground against the building, repeatedly, and that is a different problem from a wet afternoon. It is worth treating as drainage rather than as weather.
They do, faster here than in most places. A pit with a grate over it collects everything that lands near it, and once the leaf litter packs down it stops taking water long before it looks full. It is a straightforward clear and it is worth doing before the wet weather rather than during it.
No, and telling them apart matters. A sewer blockage affects fixtures inside the house and does not care about the weather. A leaf-loaded gutter, downpipe or pit only misbehaves when it rains and does not touch anything indoors.
Wipes, well ahead of everything else, whatever the packet claims. They do not break down, they snag inside the pipe and they gather everything behind them. Fat and hair make up most of the rest.
Yes, and keep it, on any line we put a camera down. It is the evidence behind whatever gets recommended.
Clearing a blocked drain is $150 to $400. Clearing gutters, downpipes and pits is $250 to $550 depending on the property. A camera inspection is $250 to $450. Jetting is $400 to $700.
