Carpet Installation
Carpet Installation near you
Carpet is the soft floor in an Australian house: bedrooms, lounge rooms, a home office, the hallway upstairs and the stairs themselves. Laying it well has less to do with the roll you picked in the showroom than with what happens underneath and around it — lifting the old covering, checking and preparing the base, laying underlay, fixing gripper around the perimeter, stretching the carpet tight, and finishing it neatly at the doorways and against the skirting.

Two Australian realities shape the work more than the fibre does. The first is the age of the house. Pulling up an old floor covering in a home built before the late 1980s can disturb asbestos, which appears in old vinyl flooring, in the paint-on adhesive that stuck it down, and in the bituminous felt underlayers once laid below carpet and linoleum. The second is moisture. Carpet is absorbent, so a damp slab, a slow leak or a run of humid coastal weather becomes a mould problem rather than something that quietly dries out.
Where carpet may go is partly settled by the building rules as well. Wet areas carry their own requirements under the National Construction Code housing provisions, and carpet belongs outside them. On stairs, the code sets slip-resistance classifications for tread surfaces and nosings, which is worth knowing before a deep pile is chosen for a staircase in a house with small children or older adults.
Carpet constructions and fibres sold in Australia
- Cut pile: the loops are sheared so the yarn tips stand up, giving the plush and textured carpets that feel softest underfoot and show footprints most readily.
- Loop pile: the loops are left uncut, which wears well in a hallway but can be snagged and unzipped along a row by a pet's claws.
- Twist pile: tightly twisted cut yarn that hides footprints and vacuum marks, a sensible choice for a lounge room that actually gets used.
- Wool and wool-rich blends: naturally resilient and good at disguising soil, and they need cleaning methods and products suited to wool.
- Solution-dyed fibres: the colour runs through the fibre rather than sitting on the surface, which matters in rooms taking hard sun through large windows.
- Polypropylene: shrugs off moisture and fades slowly, but it crushes underfoot in a busy hallway and tends to hold oily soil.
- Carpet tiles: laid as squares and lifted individually, so a stained or damaged patch can be swapped out without disturbing the rest of the room.
Underlay, gripper and everything the carpet actually sits on
Underlay is not cushioning for comfort alone. It absorbs the impact of each footfall so the carpet backing and fibres wear more slowly, it adds warmth and quiet, and it gives a stretched carpet a consistent surface to lie on. Thicker and softer is not automatically better: an underlay that is too soft lets the carpet flex at every step, which works the seams loose and brings on ripples, and a firmer, denser underlay generally suits loop carpets and stairs.
Around the perimeter goes gripper, the thin timber strip of angled pins that holds the stretched carpet at the wall, nailed into a timber floor or fixed with masonry fixings into a slab. The gap left between the gripper and the skirting is where the carpet edge is tucked, so it is set to suit the thickness of the carpet being laid. Ask what happens where the carpet meets tile, timber or a doorway, because transition strips and stair nosings are separate items and a thin quote is often thin precisely there.
How a carpet is measured, seamed, stretched and finished
Carpet comes off a roll of fixed width measured in metres, so the installer measures each room and works out a seam plan before anything is ordered. A good plan keeps the pile lying the same way in every piece, allows extra for matching a pattern, and puts seams out of doorways and away from the strongest window light, where a join shows most. Ask to see it, because it explains the quantity on the quote.
On the day, the base is cleared and made sound: squeaking boards refastened, a rough slab ground back or patched, and any damp patch investigated rather than covered over. Gripper is fixed around the room, underlay is laid inside it and joined, and the carpet is cut and joined with heat-activated seaming tape so the backings bond and the join settles into the pile.
Then it is stretched. A power stretcher braced across the room pulls the carpet tight so it hooks onto the gripper and stays flat. A knee kicker alone cannot tension a room-sized carpet, and carpet that was never properly stretched ripples within a season, wears along the ridges and turns into something to trip over. Doors may need to be taken off and trimmed where the new carpet and underlay sit higher than what came out.
Asbestos under an old floor covering, and the tools that must not touch it
Before an old covering comes up, what sits beneath it has to be identified, and on a carpet job the risk is usually one layer further down. The national asbestos product register records vinyl flooring and tiles produced prior to the 1980s and in use prior to 1990, with an asbestos content that could range between 20 and 45 per cent, underlays of asbestos cement flat sheeting or asbestos felt, and paint-on adhesives that may themselves contain asbestos, particularly if black in colour. The same register notes that non-asbestos flooring was often overlaid on top to reduce the cost and workload of removal, so a newer-looking floor proves nothing at all.
The register lists a second material that belongs squarely to this trade. Bituminous membrane in felt rolls and compounds, made from the 1900s through to the 1970s, was used for waterproofing and termite prevention as well as a durable underlayer below carpet or flooring such as linoleum or vinyl. If your house is of that era, the black felt under the old carpet is something to test rather than tear out.
Who may remove it is set by work health and safety law rather than the building rules, and it differs by state. In New South Wales a homeowner can remove less than 10 square metres of non-friable asbestos themselves, or a tradesperson can remove less than 10 square metres on the homeowner's behalf. Removal of more than 10 square metres of non-friable asbestos, or of any amount of friable asbestos, requires a licensed asbestos removalist, and all friable asbestos must be removed by a Class A licensed asbestos removalist.
- High-pressure water spray, jets and compressed air should never be used on asbestos material.
- High-speed power tools such as angle grinders, sanders, saws and drills — and even brooms, which also raise fibres — may only be used where the tool is enclosed during use, or is designed to capture or suppress airborne asbestos and is used in accordance with its design.
- SafeWork NSW puts the era plainly: if you are renovating or working on a home or building built before the late 1980s, it may contain asbestos.
- Agree in writing what happens, and who pays, if a sample comes back positive once the carpet is already up — it is the most common reason a flooring quote changes.
Carpet on stairs: slip resistance, nosings and what the code asks for
Stairs are the one place where a carpet choice runs into a building requirement. The housing provisions require treads to have either a surface with a slip-resistance classification not less than that listed in Table 11.2.4 when tested in accordance with AS 4586, or a nosing strip with a classification not less than that listed. The table sets P3 or R10 for a dry tread surface and P4 or R11 where the surface is wet, with P3 dry and P4 wet for a nosing or landing edge strip.
There is a matching requirement at landings: where the edge of a landing leads to the flight below, the surface must meet the classification for not less than 190 millimetres from the stair nosing, or a nosing strip must do it instead. What follows for a homeowner is practical rather than technical. A dense, low pile stretched tight gives surer footing on a stair edge than a deep plush, every tread needs underlay cut to fit rather than one loose sheet running over the nosings, and open sides, winders and landings all add cutting time — so mention them when you describe the job.
Who needs a licence to lay carpet in your state
There is no national carpet-laying licence, and carpet is not a separate trade class in most states. Queensland is the clearest illustration. The QBCC's list of trade licence classes runs from air handling duct installation through to waterproofing and includes floor finishing and covering (hard sector), wall and floor tiling and waterproofing — but no soft-flooring or carpet class at all.
New South Wales licenses by the value of the work instead of by the trade. You must have a contractor licence to carry out, advertise or contract for building or trade work valued above a set figure in labour and materials including GST, so carpeting a whole house commonly needs a licensed contractor while a single bedroom may not, and carpet laid as part of a renovation falls inside general building work regardless of its own value.
The licensed work on a carpet job tends to sit on either side of the carpet itself: asbestos removal above the unlicensed limits, any plumbing, and any electrical work. Ask which licence the business holds and in which state, then check the number on that regulator's public register before you accept a quote. A trade association logo is not a licence number.
Carpet, humidity and mould in an Australian home
- Vacuum before soil works its way down into the pile, since grit cuts fibres and dulls a carpet faster than foot traffic does.
- Deal with a spill or a leak the same day, because water that reaches the underlay and the base below will not dry out on its own under a stretched carpet.
- Keep rooms ventilated: NSW Health notes that mould may grow indoors in wet or moist areas that lack adequate ventilation, and lists carpets among the places it grows.
- Run air conditioning or a dehumidifier through a humid summer or a northern wet season, when a closed-up house holds moisture in its soft furnishings.
- Treat a mouldy carpet as a decision rather than a scrub — NSW Health advises that absorbent materials such as carpet may need to be professionally cleaned or replaced if they are contaminated with mould.
- Put mats at external doors and felt pads under heavy furniture, and lift rather than drag anything heavy so the carpet is not pulled off its gripper.
- North-facing and west-facing rooms take the strongest sun in the southern hemisphere, so unshaded glass fades a carpet unevenly and leaves a line where a rug once sat.
Consumer guarantees, a written scope, and finding carpet installers on LokalMatch
Australian Consumer Law gives you guarantees on the service that a business cannot take away. Service providers must carry out all services using an acceptable level of care and skill, services provided and any resulting products must be fit for any stated purpose, and services must be supplied within a reasonable time if there is no agreed time frame. The ACCC is blunt about it: the basic rights covered by consumer guarantees cannot be taken away by anything a business says or does. A written scope then adds the detail those guarantees cannot supply — who lifts and disposes of the old covering, what happens if it needs testing first, which underlay is being used, whether the carpet is power stretched, who moves the furniture, and what is included at doorways and on the stairs.
LokalMatch is how homeowners reach the businesses that do this work. You describe the job once — the rooms, the stairs, the floor that is there now, the age of the house and your postcode — and carpet installers covering your area get in touch with you directly. Those businesses pay LokalMatch for the requests they take on; describing a job costs a homeowner nothing. LokalMatch does not lay carpet, does not quote or set prices, and does not vet, rank or recommend any of the businesses that respond, so checking licences, insurance and past work stays with you.
Carpet Installation: frequently asked questions
Can carpet be laid straight onto a concrete slab?
Yes, and it is ordinary in most of the country. The gripper is fixed to the slab with masonry fixings instead of nails, and the underlay is laid inside it as usual. The thing to settle first is moisture, because carpet and underlay are absorbent and a slab that is passing moisture upward has nowhere to vent it. Any damp patch, efflorescence or musty smell should be investigated before the carpet goes down rather than after.
Is it safe to pull up the old carpet myself in an older house?
Not until you know what is under it. SafeWork NSW warns that a home built before the late 1980s may contain asbestos, and the national product register records asbestos in vinyl flooring and tiles made prior to the 1980s, in the paint-on adhesives beneath them particularly where black, and in bituminous felt used as an underlayer below carpet from the 1900s to the 1970s. Testing comes before lifting, and power tools and compressed air are the wrong response to a suspect layer.
Do I need a licensed contractor to install carpet in Australia?
It depends on the state and the size of the job rather than on carpet itself. Queensland's list of QBCC trade licence classes has no soft-flooring or carpet class, covering floor finishing and covering (hard sector), wall and floor tiling and waterproofing instead. New South Wales requires a contractor licence for building or trade work valued above a set figure in labour and materials including GST, so a whole-house job commonly needs one while a single room may not.
Can carpet go in a bathroom or laundry?
It should not. The housing provisions treat wet areas separately, requiring building elements in them to comply with AS 3740, the shower floor to be waterproof including any hob or step-down, and the floor of the room to be water resistant where it is concrete or fibre-cement and waterproof where it is timber. Carpet is absorbent, holds water against the floor and is exactly the sort of material NSW Health flags as needing professional cleaning or replacement once mould gets into it.
What underlay should I choose?
Match it to the carpet and the room rather than picking the softest one available. A very soft underlay lets the carpet flex at every footfall, which strains the seams and backing and encourages ripples, so loop carpets and stairs generally call for something firmer and denser. Carpet manufacturers often specify the underlay their warranty depends on, so choose the two together and keep the paperwork.
Why do carpets ripple, and can it be prevented at installation?
Ripples mean the carpet is no longer under tension. Usually it was never stretched hard enough in the first place, because a knee kicker alone cannot tension a room-sized carpet the way a power stretcher braced across the room can. An underlay that is too soft, gripper that has let go of a slab, or heavy furniture dragged across the floor will all loosen it as well. Ask directly whether the carpet will be power stretched.

What affects the cost of carpet installation
Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Floor area and the number of rooms
- Type and grade of flooring
- Removal of the existing floor
- Subfloor repairs or levelling
- Stairs, angles and custom cuts
- Trim, transitions and baseboards
How to compare carpet installers before you hire
- Choose an installer who works regularly with the type of flooring you want, since hardwood, tile, vinyl and carpet each need different skills.
- Ask them to check the subfloor and moisture levels before giving a final price.
- Get a written quote that covers removal of the old floor, subfloor prep, underlay, trim and transitions.
- Ask whether you or the installer will supply the flooring, and who is responsible for ordering extra for waste.
- Look at recent work in person or in photos, paying attention to seams, edges and transitions.
Questions to ask carpet installers before you hire
- Will you remove and dispose of the old flooring?
- How will you check and prepare the subfloor?
- Is my space suitable for this type of flooring, especially in a basement, kitchen or bathroom?
- Are baseboards, transitions and stair nosings included?
- Will you move the furniture and appliances, or should I?
- Does your workmanship warranty cover problems like lifting, gaps or cracked tiles?
Carpet installation permits and local rules
Some carpet installation work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
