Floor Sanding & Polishing FAQs — Auckland
Clear answers about timber floor sanding, polishing, refinishing, coatings, cost, drying time, dust, repairs and aftercare for Auckland homes and businesses.
Quick answer: Most timber floors can be sanded, polished, recoated or refinished if the boards are still sound and thick enough. The right option depends on the floor condition, coating wear, stains, repairs, timber species and the finish you want. This FAQ is designed to answer the real questions Auckland homeowners ask before booking a floor sanding job.
Useful floor sanding tables
| Floor size | Typical timeframe | Notes |
|---|---|---|
| 40–75 m² | About 3–4 days | Common for a unit, small home area or part-house job. |
| 75–100 m² | About 4–5 days | Common for a larger open-plan or whole-home floor area. |
| 100+ m² | About 4–6+ days | Repairs, stairs, staining or slower coatings can extend timing. |

Quick answers
How much does floor sanding and polishing cost in Auckland?
Most Auckland timber floor sanding and polishing jobs are priced by square metre, with the final quote depending on floor size, timber condition, coating choice, repairs, access and whether staining or gap filling is needed. As a broad guide, full sanding and refinishing often sits around $45–$75 per m², while lighter screen-and-recoat work may start lower. For a faster estimate, use our floor sanding cost calculator.
Is floor sanding cheaper than replacing timber floors?
Yes, in most cases sanding and refinishing is much cheaper than replacing sound timber boards. If the floor still has enough thickness and the boards are stable, sanding can remove worn coatings, scratches and dull patches before a new protective finish is applied. Replacement is usually only needed when boards are rotten, badly cupped, too thin or structurally damaged.
How long does floor sanding and polishing take?
A small-to-medium Auckland home often takes 3–5 days, depending on floor size, coating system, repairs, weather and drying time. Larger homes, stairs, staining, repairs or multiple rooms can take longer. The coating type also matters: some water-based finishes dry faster, while oil-based or solvent-based systems may need more airing and curing time.
Can I stay in my house while the floors are being sanded?
You may be able to stay during early sanding stages if only part of the home is affected, but most people arrange alternative accommodation during coating and drying. You cannot walk on wet coatings, and some finishes can have a strong smell while curing. It is best to plan around access, pets, children and ventilation before the job starts.
What is the difference between sanding, polishing, refinishing and recoating?
Sanding removes the old surface and levels the timber. Polishing usually refers to applying the final protective coating and sheen. Refinishing is the full renewal process, which may include sanding, repairs, staining and new coatings. Recoating is lighter: the existing finish is cleaned, lightly abraded and coated again when the timber underneath is still sound.
Cost and quote questions
What affects the price of a floor sanding job?
The main price factors are floor area, timber condition, coating type, number of coats, repairs, stain work, gap filling, stairs, edge detail, carpet or vinyl removal, staple removal, furniture handling and site access. A clean open room is quicker than a floor with old glue, tacks, water stains, heavy wear or many edges.
Is there a minimum charge for small floor sanding jobs?
Many floor sanding companies have a minimum charge for small areas because travel, setup, machines, edging, vacuuming and coating time are still required. A hallway, bedroom or small repair area can take less square metres but still needs proper preparation and drying time. Ask for the minimum charge before booking a small job.
Can you give a quote over the phone?
A phone estimate is possible if you know the approximate square metres, timber type, current condition and finish you want. It is still only a guide. An on-site quote is more accurate because the floor can be checked for coating wear, old staples, board damage, stains, height differences, repairs, access and whether the boards are suitable for sanding.
Does carpet, lino or staple removal cost extra?
Usually yes. Removing carpet, vinyl, lino, tacks, staples, smooth-edge strips or old adhesive can add labour before sanding begins. Staples that snap off may need grinding or careful removal so they do not damage sanding equipment. This should be discussed during the quote so the preparation cost is clear.
Is sanding a rental property worth it?
Polished timber floors can be a practical option for rentals because they are easier to clean than carpet and less likely to hold stains, dust mites and odours. For rental properties, a durable satin or low-sheen finish is often a good choice because it hides minor marks better than high gloss and is easier to maintain between tenancies.
Before the job
Do I need to move furniture before floor sanding?
In most cases, furniture and personal items need to be removed before sanding starts. Heavy furniture, appliances, curtains and fragile items should be moved or protected. This gives the sanding team clear access and helps prevent dust, coating marks or accidental damage. Confirm furniture responsibilities before the job begins.
What happens to the sanding dust and rubbish?
Modern floor sanding machines collect much of the dust through vacuum systems, and the floor is usually vacuumed between sanding and coating stages. There will still be some fine dust around the work area. Rubbish from sanding, old coatings, removed staples or flooring waste should be discussed in the quote so you know what will be taken away.
How much dust does floor sanding create?
Floor sanding is much cleaner than it used to be, but it is not completely dust-free. Professional machines with attached dust extraction remove a large amount during the process. It is still sensible to cover electrical appliances, remove curtains where needed, close off nearby rooms and expect some fine dust after the job.
How far in advance should I book floor sanding?
Book as soon as you have a firm renovation or move-in date. Around two weeks may be enough for some jobs, but busy periods, larger homes, staining, repairs or tight renovation schedules may need more notice. If carpet, painting or moving dates are involved, book earlier so the floor work fits the wider project.
Should painting or carpet installation happen before or after floor sanding?
Floor sanding is usually best done after messy building work but before new carpet is laid in nearby areas. Fresh carpet can create dust that may settle into wet coatings. Painting timing depends on the project: walls are often painted before floors, with touch-ups after, but skirting boards and final details should be planned carefully.
During sanding and polishing
What is the floor sanding and polishing process?
The usual process is inspection, preparation, coarse sanding, edge sanding, medium and fine sanding, dust removal, optional repairs or staining, then application of the chosen coating system. The exact process changes with timber type, age, old coating, moisture, damage, stain choice and the finish required.
How many coats of finish do you apply?
Many timber floor jobs use three coats of polyurethane or a product-specific coating system, but the right number depends on the finish type, traffic level, timber condition and manufacturer instructions. High-use homes, rentals or commercial spaces may need a more durable system than a low-traffic bedroom.
Can nail holes and gaps be filled before polishing?
Yes, nail holes, small cracks and some gaps can often be filled before the final finish. Not every gap should be filled, especially on older native timber floors that naturally move with moisture and seasons. The best approach depends on the size of the gaps, floor age, timber type and the look you want.
Can loose or damaged floorboards be repaired before sanding?
Often, yes. Loose boards, squeaks, damaged sections, split boards and localised problems can sometimes be repaired before sanding and refinishing. If boards are rotten, too thin or badly water-damaged, replacement may be needed before the floor can be finished properly.
Will sanding remove deep scratches and dents?
Sanding can remove many surface scratches, old coating marks and shallow damage. Deep dents, heavy gouges, burns, black water marks or stains that have soaked deep into the timber may not fully disappear. In those cases, repairs, board replacement, staining or a darker finish may be recommended.
Finishes, smell and drying
What finish options can I choose?
Common timber floor finish options include water-based polyurethane, oil-based polyurethane, moisture-cured polyurethane, hardwax oil and natural oil systems. Sheen options often include matte, low-sheen, satin, semi-gloss and gloss. The best choice depends on timber species, sunlight, traffic, smell sensitivity, maintenance and the look you want.
What is the difference between water-based and solvent-based polyurethane?
Water-based polyurethane is usually lower odour, faster drying and clearer in colour, so it can suit lighter timbers and homes where smell is a concern. Solvent-based or moisture-cured polyurethane can be very durable but has a stronger smell and can amber the timber. The best option depends on the floor and how the space is used.
How long does the smell last after floor polishing?
Water-based coatings usually have much less lingering smell. Solvent-based or moisture-cured coatings can smell stronger during and after application. With good ventilation, the strong smell may reduce after 24–48 hours, but curing continues for longer. Always follow the product and contractor guidance before sleeping in the space.
How soon can I walk on newly polished floors?
Light foot traffic is often possible after 24–48 hours, depending on the coating, temperature, humidity and ventilation. Socks are safer than shoes at first. Furniture, rugs, pets and heavy use usually need longer. Full cure can take days to weeks depending on the product, especially with oil-based systems.
Which sheen hides scratches best: matte, satin or gloss?
Lower-sheen finishes such as matte, low-sheen or satin usually hide dust, small scratches and everyday wear better than high gloss. Gloss can look striking but reflects more light, which makes marks and imperfections easier to see. Satin or low-sheen is often a practical choice for busy Auckland homes and rentals.
Can you make sample patches before choosing a stain or finish?
Yes, sample patches are a smart way to see how a stain, coating or sheen looks on your own timber. Rimu, matai, kauri, pine, oak and engineered timber can all react differently. Samples are especially useful when matching old and new boards or choosing between a natural, darker or warmer colour.
Floor problems and suitability
Can old timber floors be sanded and polished?
Many old Auckland timber floors can be sanded and polished if the boards still have enough thickness and are structurally sound. Older villa and bungalow floors may need repairs, careful sanding, gap decisions, stain correction or a finish suited to native timber such as rimu, matai or kauri.
Can engineered timber floors be sanded?
Some engineered timber floors can be lightly sanded or refinished, but only if the top timber veneer is thick enough. Thin veneer floors may not be suitable for full sanding. The floor should be inspected first so the sanding does not cut through the wear layer.
Can black water stains around nails be removed?
Sometimes they can be reduced, but not always removed completely. Black stains around nails or wet areas can penetrate deep into the timber. Sanding may reveal how deep the stain is, but there is no guarantee. Options may include board replacement, darker staining, colour blending or accepting some character marks.
Can pet stains or dark marks be sanded out?
Light surface marks may sand out, but deep pet stains, urine marks or dark moisture staining can be difficult because they may sit below the surface. After inspection, the options may include extra sanding, stain blending, board replacement or using a finish colour that reduces the contrast.
What happens if my floorboards are too thin to sand again?
If the boards are too thin, heavily cupped, previously over-sanded or structurally weak, a full sand may not be safe. In that case, a light screen and recoat, local repair, board replacement or full replacement may be recommended. A site inspection is the safest way to decide.
Which timber floors can you work with?
Common Auckland timber floors include rimu, matai, kauri, pine, oak, kwila, parquet, engineered timber and other hardwoods. Each timber sands and finishes differently. Native timbers can have strong colour variation, while oak and modern hardwoods may suit different coating and staining systems.
Maintenance after polishing
How long do polished timber floors last?
A well-sanded and properly coated timber floor can last many years, and the timber itself can last for decades when cared for. The coating life depends on foot traffic, pets, sunlight, cleaning products, grit, furniture pads and maintenance. Many floors benefit from a maintenance recoat before the finish wears through.
How do I care for floors after sanding and polishing?
Use soft pads under furniture, sweep or vacuum grit regularly, clean with a suitable timber-floor cleaner and avoid soaking the floor with water. Do not use harsh chemicals, steam mops or abrasive pads. Keep rugs off until the coating has cured enough, and follow the contractor’s aftercare advice.
Can I wear high heels or stilettos on polished timber floors?
Pointed heels can dent timber floors because they place a lot of pressure on a very small area. Stilettos, stones in shoes, dragging furniture and pet claws can all mark the finish or timber. Use door mats, furniture pads and regular cleaning to reduce wear.
When should a timber floor be recoated?
A floor should be recoated before the protective finish wears through to bare timber. Signs include dull high-traffic areas, fine surface scratches, patchy sheen or a finish that no longer cleans well. If the timber is still protected, a screen and recoat may be enough. If bare timber is exposed, full sanding may be needed.
Are polished timber floors good for allergies?
Timber floors can be easier to keep clean than carpet because they do not trap dust, mites and allergens in the same way. Regular sweeping and damp cleaning with the right product can help keep the floor cleaner. This is one reason many homeowners and landlords prefer polished timber over old carpet.
Auckland homes and service areas
Do you sand floors for both homes and businesses?
Yes, floor sanding and polishing can be done for Auckland homes, rental properties, villas, apartments, offices, shops, halls and other commercial spaces. The finish system should match the traffic level, maintenance needs and how quickly the space needs to be used again.
Do Auckland weather and humidity affect floor sanding?
Yes. Temperature, humidity and ventilation can affect drying, curing and how timber moves. Auckland homes near the coast, older villas, damp subfloors or poorly ventilated rooms may need extra care. Coating choice, timing and airflow should be considered before and after the job.
What Auckland suburbs do you service?
Floor Sanding Auckland Experts services suburbs across Auckland, including West Auckland, Central Auckland, North Shore, East Auckland and South Auckland. Availability depends on job size, timing and access. If you are unsure whether your suburb is covered, ask for a quote.
How do I know whether to sand, recoat, refinish or replace my floor?
If the floor is dull but the coating is still mostly intact, recoating may be enough. If there are deeper scratches, bare timber, old coatings or colour problems, refinishing may be better. If boards are rotten, too thin or badly damaged, replacement may be needed. Our recoat vs refinish vs replace guide can help you decide.
Important: Every timber floor is different. The safest recommendation comes from checking the actual boards, old coating, repairs, moisture, access and the finish you want.
