How to prepare a room for a new flooring installation

Getting a new floor laid should be the easy part of a renovation, but most delays begin before the fitter reaches the door. Furniture left in place, an underestimated measurement or a damp subfloor can hold up the job and leave you with a room you cannot use. A little preparation makes the installation cleaner, safer and far less disruptive.

Dickinson's Furnishers has been furnishing homes since 1878, and its designers, sales advisers and fitters understand how floors behave as well as how they look. The same basics apply in Australia, where timber, engineered timber, bamboo, laminate, carpet and vinyl planks are all popular. Local conditions simply make them worth taking seriously.

Think of preparation as clearing the workspace, checking the surface beneath the old floor and agreeing on the finish with your installer. This guide explains how to prepare a room for a new flooring installation, from the first measuring tape to the moment you move the furniture back. The aim is a smooth handover, not a DIY shortcut around work that needs the right tools or qualifications.

Plan the layout before anything is moved

Start with the room, not the sample. Sketch its shape, note doors, alcoves, columns, stairs and the direction in which the boards or sheets will run. Measure the length and width in several places, including narrow sections near wardrobes and built-in cupboards. Record the floor-to-ceiling height of door openings as well, because thick timber or underlay can change the clearance at a hinged door.

Ask your flooring supplier for the installation requirements that apply to your chosen product. They may specify room-size limits, expansion allowances, the type of subfloor, moisture limits, a particular underlay or a required acclimatisation period. A written checklist also prevents a dispute later: some timber boards need to condition inside the building, while resilient flooring may need a flat, clean and suitably dry slab.

Keep the plan practical. If the floor continues into a hallway or another room, decide whether the installer will handle the joint and what trim will be used. For patterned carpet, tiles or herringbone boards, allow for more cutting waste than a straight plank layout. Ordering an extra ten per cent is sensible for a straightforward rectangular room, but complicated layouts should be calculated by the installer.

Check the subfloor and existing finishes

A new floor can only be as good as the surface underneath. Remove loose carpet, underlay, staples, protruding nails and old adhesive, then sweep away dust and grit. Fill holes and repair cracked or displaced boards. Do not cover damp patches, water marks or mould with the new flooring; have them investigated and fixed first, and keep the ventilation going while any wet trades dry the area.

Concrete slabs are common in Australian homes, so ask the installer how the slab will be assessed for moisture and whether a suitable membrane or levelling compound is needed. The flooring maker may set a moisture limit; readings should be taken and recorded before the slab is covered. Timber subfloors need checking for movement, squeaks and fixing points that could telegraph through the finish. Expansion joints must remain in the same position in the finished floor rather than being hidden.

The climate matters. Sydney's humid coastal conditions, Melbourne's damp winters and sharp temperature changes, and Brisbane's muggy, storm-prone summers can each affect how timber, bamboo and vinyl move or bond. Expansion gaps, moisture control and the flooring manufacturer's guidance are not optional details; they protect the installation through the seasons that follow.

Clear the room and protect what remains

Move furniture, rugs, curtains and pictures out where you safely can. If a wardrobe or a large cabinet is built in, ask the fitter whether it must be removed or can be worked around. Empty drawers, release fixed appliances and protect any item that has to stay. Heavy pieces should be lifted with enough help rather than dragged over the old floor, which may be weak, wet or uneven.

Leave a clear route from the entrance to the work area, with enough room for tools, offcuts and a safe place to store materials. Keep extension leads and hoses out of walkways, cover any surviving floor with heavy-duty protection, and check that the installer has access to power, ventilation and a suitable water point if needed. Keep the job site secure from children and pets, and give your flooring tradie a clear brief on what must stay in place.

If the room contains a fireplace or bio-ethanol heater, confirm the hearth protection and ventilation before work starts. Glass, ash and moving screens can mark timber, vinyl or carpet, while hot equipment needs safe clearances. Browsing contemporary fireplace designs can help you picture how the finished floor will meet the feature, but the appliance instructions and local fire-safety rules should govern the layout.

Recommendations for a smooth installation day

Use the final walk-through with your installer as a shared checklist. Keep your measurements, product details and floor plan nearby, and make sure everyone agrees on the direction, trim, transitions and any preparation that remains to be done.

• Confirm the flooring, underlay, trims and adhesive or fixing system match the written order, and check the delivered batch or dye lot before installation begins.
• Photograph the empty room, subfloor, skirting and junctions with adjoining floors so there is a clear record of their condition beforehand.
• Ask the installer to flag boards that lift, split or look inconsistent, and agree whether offcuts should be stored for possible future repairs.
• Remove the final obstacles, including doormats and loose cables, while keeping an accessible path and a protected position for tools and materials.
• Check that the room is ventilated and the product's safety instructions are available, especially when adhesives, primers or wet trades are involved.
• Agree on when furniture and foot traffic may return; newly bonded floors often need longer than the fitting itself, particularly over a long weekend.

Arrange the return of furniture thoughtfully. Use felt pads or suitable protective feet beneath every leg, and keep rugs away until the adhesive has cured and the maker's stated traffic period has passed. Heavy chairs should not be rolled directly across a finished floor, and kitchen appliances should not be dragged into position.

Coordinate the finish and the handover

Keep the room clear until the finish has settled and the installer has completed a final inspection. Some adhesive-based installations need ventilation and a prescribed curing period before rugs, furniture or heavy traffic return. Timber may need a settling period too. If the flooring is underfloor heated, follow the heating supplier's commissioning schedule rather than switching it on immediately, and have electrical work carried out by a licensed electrician.

Ask for care instructions, spare boards or offcuts, product documentation and written details of both the flooring warranty and installation warranty. Some Australian flooring is sold as supply only, with installation quoted separately; others come as a package, so compare the full scope rather than the advertised square-metre price. Keep receipts, the signed quote and records of any outstanding issues together in one folder.

A good handover also includes knowing how to clean the new surface without damaging it. Vacuum timber and carpet gently, use the approved cleaner for vinyl, and wipe spills promptly rather than letting them sit. Note the recommended maintenance schedule and any products to avoid, especially for coated timber and delicate carpet fibres.
