Chimney Sweep Cost Calculator
A chimney sweep is a cheap job that gets expensive when access is hard or the flue has been neglected. Choose your flue type, roof access and service level for a realistic Australian price.
Creosote builds up fastest when you burn unseasoned wood or run the heater choked down overnight for a slow burn. A hotter, shorter fire with dry hardwood produces far less deposit than a smouldering one, which means fewer sweeps and a safer flue.

💰 Ways to save
- Book in late summer or early autumn rather than on the first cold snap. Sweeps are quiet in February and March and often discount, whereas from late April the phone runs hot and you are competing for a booking with everyone else who just lit their first fire and smelled smoke in the room.
- Have both fireplaces done in the same visit if you have two. The travel, sheeting, vacuum setup and roof access are already paid for on the first flue, so the second typically adds only $120 to $200 rather than a full service price.
- Burn only properly seasoned hardwood, ideally split and stored under cover for twelve months or more. Wet or green wood roughly doubles creosote deposition, which turns an annual sweep into a twice-yearly one and increases the odds of paying for glazed tar removal at more than double the standard rate.
- Fit a cowl once rather than paying for nest removal repeatedly. A stainless cowl or bird guard costs a couple of hundred dollars fitted and eliminates both the annual nesting problem and the rain that accelerates corrosion inside a steel flue.

Understanding chimney sweep costs in Australia
What a chimney sweep costs in Australia
A standard chimney sweep in Australia costs between $200 and $400 in 2026 for a single accessible flue, with most metropolitan sweeps sitting around $250 to $330 for a freestanding wood heater on a single storey home. An open masonry fireplace usually costs slightly more because there is more surface area and more mess to contain, and a built-in insert or heat exchanger unit costs more again because the baffles have to come out to reach the deposits behind them. Gas log fire flues are the cheapest of the group, generally $150 to $250, since they do not accumulate creosote and the visit is really an inspection with a light clean. Regional pricing varies more than metro pricing, largely because travel is a bigger share of a country sweep's day.
Why access changes the price so much
The number of storeys and the roof pitch are the biggest multipliers after flue type. A single storey home with a low pitch lets the sweep work efficiently from a ladder with a straightforward setup. A two storey home requires longer ladders, more time to set up safely and often a spotter, and typically adds 25 to 35 per cent. A steep tile roof, a three storey terrace or a chimney set back from the roof edge can push the job to one and a half times the base rate, because the sweep may need a harness, a roof anchor or a second person on site. Some operators will decline steep tile roofs entirely rather than take on the risk, which is worth knowing before you spend a week ringing around.
Creosote, glazed tar and neglected flues
Creosote is the condensed residue of unburnt wood gases and it comes in stages. Light, flaky stage one deposit brushes out easily and is what a well maintained annual sweep removes. Stage two is harder and more granular. Stage three is glazed creosote, a shiny tar-like coating that has effectively baked onto the liner, and it will not brush off. Removing it requires rotary chain or whip tooling and sometimes chemical treatment applied over several burns, which is why that service is priced at roughly double a standard sweep. A flue that has gone several years without service frequently arrives at stage two or three, so the first visit after a long gap is rarely a standard price. Glazed creosote is also the main fuel for a chimney fire, which is the reason the price difference matters less than getting it out.
How often a flue needs sweeping
The general Australian guidance is once a year for a wood heater or open fireplace used through a normal winter, timed before the season starts rather than after it. Households that burn heavily, burn softwood, or run the heater choked down overnight for a slow burn should consider twice a year, because low-temperature smouldering is the fastest way to build creosote. A useful practical test is to look up the flue with a torch: if the deposit on the liner is more than about three millimetres thick, it needs sweeping regardless of how long it has been. Gas log flues are on an inspection cycle rather than a cleaning cycle, but they still need checking annually for blockages, corrosion and correct draught.
What a sweep should actually do
A proper service is more than running a brush up the flue. Expect the sweep to sheet and seal the appliance opening, use an industrial vacuum to contain soot, brush the full length of the flue from the appropriate end, remove and clean baffles on an insert or wood heater, clear the firebox and ash pan, and then check the visible condition of the flue, the cowl, the flashing where the flue passes through the roof, and the door seals. A written report matters if you are buying or selling a home, or if your insurer has asked for evidence of maintenance. Camera scanning of the liner is an optional extra that is genuinely useful on an older masonry chimney where cracked parging or a failed liner is a real possibility.
Safety, insurance and what neglect costs
Flue fires are the reason this job exists. A chimney fire burns at temperatures that can crack a masonry flue or warp a steel one, and the damage is frequently not visible from inside the room afterwards. Many Australian home insurance policies expect solid fuel heaters to be maintained in accordance with the manufacturer's instructions, and a claim following a flue fire in a chimney that has not been swept for years is an argument you do not want to have. Keep the invoice or the inspection report each year. Set against a replacement flue at $1,500 to $3,000, or the consequences of a house fire, an annual sweep at around $300 is one of the cheapest pieces of home maintenance on the calendar.
Frequently asked questions
How much does a chimney sweep cost in Australia?
A standard sweep costs $200 to $400 in 2026, with most metro operators charging $250 to $330 for a single accessible flue on a single storey home. Gas log flues are cheaper at $150 to $250, while heavy creosote or glazed tar removal can reach $450 to $650.
How often should a chimney be swept?
Once a year for a wood heater or open fireplace used through a normal winter, ideally before the season starts. Heavy users, anyone burning softwood, and households that run the heater choked down overnight should consider twice a year. As a practical test, deposit more than about three millimetres thick on the liner means it needs sweeping.
Why does a two storey chimney cost more to sweep?
Access drives the labour. Two storey homes need longer ladders, a more careful setup and often a spotter, which typically adds 25 to 35 per cent. A steep tile roof or a three storey terrace can push the price to one and a half times the base rate because a harness or roof anchor is required, and some sweeps decline steep tile roofs entirely.
What is glazed creosote and why is it more expensive to remove?
Glazed creosote is a shiny, tar-like third stage deposit that has baked onto the flue liner and will not brush off. It requires rotary chain or whip tooling and sometimes chemical treatment over several burns, so it is priced at roughly double a standard sweep. It is also the main fuel for a chimney fire, which makes removing it a safety issue rather than a cosmetic one.
Can I sweep my own chimney?
You can buy a rod and brush kit, but the risks are the roof and the mess. Without an industrial vacuum and a sealed appliance opening, soot ends up through the room, and DIY sweeping does not remove baffles on an insert, inspect flashings, or identify a cracked liner. If your insurer expects documented maintenance, a professional invoice or report is also worth having.
What does a chimney sweep include?
A proper service sheets and seals the appliance opening, vacuums to contain soot, brushes the full flue length, removes and cleans wood heater baffles, clears the firebox and ash pan, and checks the flue, cowl, roof flashing and door seals. Ask whether a written condition report is included, particularly if you are selling or your insurer has requested evidence.
