It is usually the first big autumn storm that does it. Water pours over the front of the gutter instead of down the downpipe, there is a line of gum leaves hanging off the edge like a fringe, and you realise nobody has been up there since last year. So you start ringing around for a gutter cleaning cost, and every website quotes a different number from a different city.
We are not going to add another national average to that pile. A gutter clean on a flat block in the suburbs and a gutter clean on a two-storey house under a stand of gums in the upper Mountains are not the same job, and they should not be priced as if they were. What we can do is explain what actually moves the price, what a proper clean should include, and why the cheapest quote is sometimes the dearest one by the end of winter.
The same house can cost very different amounts to clean
Most of the price of a gutter clean is time on the roof. How much time depends on a handful of things you can mostly see from your own backyard.
How much gutter there is, and how high
Length is the starting point. Every run around the house, every verandah, carport and extension adds to it. Height matters just as much. A single-storey gutter is a fairly quick job to reach and work along, but a two-storey gutter means more setting up, more safety gear and slower, more careful work at the edge.
How hard the roof is to get onto
Plenty of homes up here sit on a slope, so a house that is single-storey at the street can be a long way off the ground at the back. Steep roof pitches, tanks or garden beds hard against the walls, and nowhere sensible to stand a ladder all add time. None of that is padding. It is the part of the job that keeps people from falling off your roof.
What is actually in the gutter
This is the one that surprises people. Dry leaf lifts out quickly. A gutter that has sat full through a wet Mountains winter is a different story. Fine gum leaf packs down into a heavy, wet mat, and given long enough it turns into something closer to compost. We regularly find seedlings growing in gutters that have been left for a few years. Getting all of that out cleanly takes far longer than a light seasonal clear, and the bags of waste have to go somewhere.
Whether the downpipes are blocked too
Clearing the gutter is only half the job if the downpipe below it is choked. Leaves and grit collect at the outlet and in the bends, and a blocked downpipe will make a freshly cleaned gutter overflow in the next storm. Flushing each downpipe and checking the water actually runs away is part of a proper clean. If the blockage turns out to be further down, in the underground stormwater line, that can become a separate job, and a good quote should say so up front.
Why the rainfall up here raises the stakes
The Bureau of Meteorology station at Katoomba sits at 1,017 metres and records mean annual rainfall around 1,411 mm, and a lot of it arrives in short, heavy bursts. The lower Mountains is drier, but it still gets the storms. When a half blocked gutter meets a downpour, the water has nowhere to go. It spills over the front or, worse, backs up under the roof edge and into the eaves.
So we think of a gutter clean as cheap protection against much bigger repair bills. Water sitting against the fascia board rots the timber. Water backing up under the tiles turns up as a stain on the ceiling. Gutters that stay wet keep the whole roof edge damp, and that is exactly where moss gets a start. A clean costs a fraction of fixing any of those.
What a proper gutter clean should include
When you compare quotes, the price only means something once you know what is in it. A clean we are happy to put our name to covers:
- Every gutter run cleared by hand, verandahs and carports included
- Debris bagged and taken away, not blown onto the garden or next door's roof
- Each downpipe flushed and checked for flow
- Valleys and the area behind chimneys cleared, since leaf piles up there too
- A look at the empty gutters for rust, leaking joints and loose brackets
- Photos of anything that needs attention
Those last two matter more than people expect. A gutter full of leaves hides its own condition. We often clear one and find the base has rusted through underneath, or a joint has been leaking for years. You want to hear about that while it is a small fix, not after the fascia behind it has gone soft.
The cheapest clean can turn out to be the dearest
A very low price usually means something has been left out. The shortcuts we see most are a quick scoop of the easy runs with the downpipes ignored, debris blown off the roof and left on the lawn, and nobody looking at the gutters once they are empty. The house looks fine from the street. Then it overflows in the first storm because the outlet is still blocked.
A roofer also notices things a general cleaner may walk straight past. Cracked or slipped tiles near the edge, a ridge cap starting to lift, rust spreading on a metal roof, a valley holding water: we spot them because fixing them is our everyday work. You are under no obligation to do anything about what we find, but you should at least know about it.
How often a Mountains block needs doing
There is no honest one size answer. It comes down to what is hanging over your roof. A house with no trees nearby may only need an occasional check. A house under gums, which drop leaf, bark and twig all year rather than in one tidy autumn fall, can fill its gutters several times a year. Most of the treed blocks we work on, from Glenbrook up to Blackheath, sit at the busy end of that.
Rather than going by the calendar, watch for the signs. Water spilling over the front edge in moderate rain. Plants sprouting out of the gutter. Gutters sagging or pulling away from the fascia under the weight. Damp marks on the eaves. Downpipes that stay dry while it is pouring. And if your property is in a mapped bushfire area, a gutter full of dry leaf heading into summer is fuel sitting on your roof, so check it before the warm weather rather than after.
If you are paying for a clean every few months, it is probably time to think about keeping the leaves out instead. We cover that honestly in whether gutter guard is worth fitting on a treed Mountains block. Guard does not do away with checks, but it can turn a regular clean into an occasional one.
Sometimes the clean shows you need more than a clean
Once the gutters are empty, now and then the honest answer is that they are past saving. Rust right through the base, joints that leak again after every reseal, or gutters that overflow even when they are clean because they are too small for the roof: all of these mean cleaning is just buying time. If that is where yours are heading, our breakdown of how new gutters are priced explains that side of things.
We handle cleaning, repairs, replacement and leaf guard as part of our gutter and downpipe work across the Blue Mountains, so there is no reason for us to push you towards the bigger job. Most of the time, a clean and a couple of small repairs are all a gutter needs.
Booking it with other roof work saves a second setup
If you already have roof work coming up, such as repairs, repointing or a restoration, ask for the gutters to be done at the same time. The access equipment is already on site, the roof is already being looked over, and you are not paying for the same setup twice. It is also worth booking a clean after any tree work near the house. A pruning job can fill a clean gutter in an afternoon.
Get a real price for your own gutters
The only way to turn all of this into a figure is to see your roof, the trees above it and how full the gutters are. We inspect and quote for free, and the quote spells out exactly what is included, downpipes and disposal and all. If your gutters are spilling over or have not been touched in a while, book a gutter clean and check or call (02) 4742 0922.
